Abstract This study investigated the effect of a social
and emotional learning skills curriculum, the You Can Do
It! Early Childhood Education Program (YCDI), on the
social-emotional development, well-being, and academic
achievement of 99 preparatory and grade 1 students
attending a Catholic school in Melbourne, Australia. One
preparatory and one grade 1 class were randomly chosen to
receive structured lessons in YCDI, delivered by their
classroom teachers over a period of 10 weeks, while the
remaining preparatory and grade 1 class served as the
control group. The lessons were designed to teach young
children confidence, persistence, organisation and emo-
tional resilience. The educational program consisted of
explicit, direct instruction lessons drawn from the YCDI
Early Childhood Curriculum taught three times a week,
supported by a variety of additional social and emotional
teaching practices. The results indicated that YCDI had a
statistically significant positive effect on levels of social-
emotional competence and well-being for the preparatory
and grade 1 students, a reduction in problem behaviours
(externalising, internalising, and hyperactivity problems)
for the grade 1 students, and an increase in reading
achievement (decoding text) for the lower achieving grade
1 students. These findings are discussed with regard to
issues concerning the role of explicit instruction in social
and emotional learning for the early years.

Introduction
The development of social-emotional competence is an
important foundation for young children’s later success and
well-being. The Center on the Social Emotional Founda-
tions for Early Learning (CSEFEL) defines social-emo-
tional development as the developing capacity of the child
from birth through 5 years of age to form close and secure
adult and peer relationships; experience, regulate, and
express emotions in socially and culturally appropriate
ways; and explore the environment and learn (Center on
the Social Emotional Foundations for Early Learning
2008).
The Collaborative for Academic, Social and Emotional
Learning (CASEL 2003) have outlined five core social and
emotional competencies that are important foundations for
young people’s well-being: self-awareness, social aware-
ness, self-management, relationship skills, and responsible
decision-making. Researchers and practitioners have
described key social-emotional skills that young children
need as they enter school, including self-confidence, the
capacity to develop positive relationships with peers and
adults, concentration and persistence on challenging tasks,
an ability to effectively communicate emotions, an ability
to listen to instructions and be attentive, and skills in
solving social problems (Shonkoff and Philips 2000). The
emergence of these social-emotional skills helps young
children feel more confident and competent in developing

relationships, building friendships, resolving conflicts,
persisting when faced with challenges, coping with anger
and frustrations, and managing emotions (Parlakian 2003).
The National Academy of Sciences reported that 60% of
children enter school with the cognitive skills needed to be
successful, but only 40% have the social-emotional skills
needed to succeed in kindergarten.
Research has indicated that, in conjunction with cognitive
competence (e.g., reading, writing, and critical thinking
skills), social-emotional competence (e.g., collaboration
skills, motivation, and study skills) is an important predictor
of academic achievement (e.g., DiPerna and Elliot 2002).
For example, based on a meta-analysis of 270 research
studies, Wang et al. (1993) found that affective and moti-
vational factors had greater influence on school learning
than peer group, school culture, or classroom instructional
methods. In another study, Bernard (2004b) found that
social-emotional competence was a significant predictor of
five-year-old children’s levels of reading achievement.
In addition, Bernard found that children considered to be
‘‘at-risk’’ for academic difficulties displayed significantly
lower levels of competence in the areas of confidence, per-
sistence and organisation.
There is some disagreement in the early childhood field
concerning optimum and developmentally appropriate
ways to teach young children social and emotional skills.
Some early childhood scholars assert that—for develop-
mental reasons—teacher-led, explicit curriculum lessons
are not appropriate for teaching social and emotional skills
to young children (e.g., Whitington and Floyd 2009). They
indicate that social and emotional development is best
fostered by placing children in carefully tailored, caring
environments with adults who respond in particular ways
(e.g., Hyson 2004). Many early childhood educators
advocate the use of games and stories as methods to teach
social and emotional competencies (e.g., Cohen 2001).
Studies have investigated the effectiveness of social and
emotional learning (SEL) programs that include formal
lessons and that begin during the preschool years and have
demonstrated positive results (e.g., Payton et al. 2008).
Joseph and Strain’s (2003) review of the efficacy of eight
social-emotional curricula found that the most successful
social-emotional approaches focus on social skills and
emotional development on a daily basis, use a systematic,
intentional approach for teaching critical skills, and
acknowledge the skills in context.
In a meta-analysis of 34 universal and targeted pre-
school prevention programs, Nelson et al. (2003) found
that, overall, SEL programs had positive effects on both
cognitive and academic outcomes in the short term (pre-
school), medium term (primary school), and long term
(high school). The results also indicated that the programs
that contained a direct teaching component (including
explicit lessons in curriculum format) and those that were
of greater intensity and longer duration had a bigger
positive effect on outcomes.
A recent review of research on the effects of pre-school
education yielded an integrated model of both approaches.
Effective teaching in early childhood education is seen to
require skillful combinations of explicit instruction, sensi-
tive and warm interactions, responsive feedback, and ver-
bal engagement or stimulation intentionally directed to
ensure children’s learning while embedding these interac-
tions in a classroom environment that is not overly struc-
tured or regimented (Pianta et al. 2009).
Some of the more popular early childhood social-emo-
tional curriculum written about in the literature include: I
Can Problem Solve (Shure and Spivack 1980), First Steps
to Success (Walker et al. 1997), and Second Step
(McMahon et al. 2000). There is some empirical evidence
about the effectiveness and implementation of these pro-
grams to teach social skills to young children and prevent
or address challenging behavior; the strength of the evi-
dence varies by program or approach (Hemmeter et al.
2006).
A SEL program that involves teachers presenting
activities from a formal curriculum that explicitly teach
young children social and emotional competencies and
which are currently being implemented in hundreds of
schools throughout Australia, is You Can Do It! Education
(YCDI) (e.g., Bernard 2002,2004a,2007). YCDI is a
cognitive-behavioural approach to teaching social and
emotional skills and competencies. It is based on a number
of social learning, educational, and cognitive-behavioural
theories, including those of Vygotsky, Ellis, Bandura, and
Seligman, which together highlight the impact of the
important role of children’s thinking and self-talk on their
emotions and behaviours.
The aim of YCDI (Bernard 2002,2004a,2007) is for all
young people to achieve positive, social, emotional, and
behavioural and achievement outcomes. According to
Bernard, these objectives can be achieved by providing
children with explicit instruction in five key social-emo-
tional competencies (the ‘Five Foundations’)—Confidence,
Persistence, Organisation, Getting Along, and Emotional
Resilience. These Foundations are supported by the explicit
teaching of 12 particular ways of thinking (‘Habits of the
Mind’)—I Can Do It, Accepting Myself, Taking Risks,
Being Independent, Giving Effort, Working Tough, Setting
Goals, Planning My Time, Being Tolerant of Others,
Thinking First, Playing by the Rules, and Being Socially
Responsible.
There have been a number of studies that have dem-
onstrated positive results for YCDI (Bernard 2006,2008;
Bernard and Walton 2011) with older school-age children.
In order to provide younger children with the opportunity

to further develop the competencies and skills emphasised
by YCDI, Bernard (2004a) developed the You Can Do It!
Early Childhood Education Program, a curriculum-based
program designed to be run by teachers with children aged
from four- to seven-years-old.
There has not yet been a controlled study that has
investigated the effect of the You Can Do It! Early
Childhood Education Program on the social and emotional
competencies, well-being, and academic achievement of
young children in Australia. This study was therefore
designed to address this issue. Three main hypotheses were
proposed. First, it was hypothesised that young children
who received the YCDI program would display signifi-
cantly greater gains in their levels of social and emotional
competence than those who did not receive the program.
Second, it was hypothesised that the young children who
received the YCDI program would also display signifi-
cantly greater gains in their levels of social and emotional
well-being than those who did not receive the program. If
this hypothesis was supported, then the YCDI group would
show a greater decrease in problem behaviours, as well as a
greater increase in positive social-emotional well-being.
Third, it was hypothesised that young children who
received the YCDI program would display significantly
greater gains in their levels of academic achievement than
those who did not receive the program. If this hypothesis
were supported, the YCDI group would show a greater
increase in their independent reading levels than the non-
YCDI group.
Method
Participants
The participants were four teachers and 100 students (from
two Prep and two Grade 1 classes) from a Catholic school
in the western suburbs of Melbourne, Australia. The par-
ticipating school had been identified as being of ‘low socio-
economic status’ according to the Catholic Education
Office (Melbourne). Approximately two-thirds of the stu-
dents who attend the school speak English as a second
language. One student departed the school during the
course of the study, leaving total of 99 (45 female and 54
male) students for whom a complete data set was available.
Of the 99 students, 42 (42.4%) were in preparatory classes
(five year olds) and 57 (57.6%) were in grade 1. English
was the main language spoken at home for 46% of stu-
dents. The next highest percentage of students (37.4%)
spoke an Asian language other than Chinese at home.
Comments written on the teachers’ questionnaires indi-
cated that the majority of these students spoke Vietnamese.
The remaining students spoke various African (4%),
Chinese (3.0%), European (8.1%), and Pacific Island (1%)
languages at home.
One preparatory and one grade 1 class were randomly
assigned to receive the YCDI curriculum. These students
received lessons from the You Can Do It! Early Childhood
Education program (Bernard 2004a,b) and delivered by
their regular classroom teachers over a 10-week period
during Terms 2, 3, and 4, 2009. The students from the
remaining preparatory and grade 1 class did not receive the
program during the study, thereby serving as a comparison
group. However, in order to avoid disadvantaging the
comparison group, the teachers of these classes began
implementing the program after the completion of the post-
program measures (in Term 4).
Measures
All four teachers participating in the study were asked to
complete two questionnaires for each student. These sur-
veys were completed immediately before and after the
implementation of the program for the YCDI classes, and
at similar times for the non-YCDI classes. Information on
the student’s gender and main language spoken at home
was also collected.
The first questionnaire used was the ACER Well-being
Survey (Teacher Form—Early Years) (Bernard et al.
2009). This survey consists of 50 items. Teachers are asked
to indicate their agreement or disagreement with each item
(e.g. ‘‘The student appears to do what is asked of him/
her.’’) on a four-point Likert scale (1 =strongly disagree,
4=strongly agree). Part 1 consists of 22 items and mea-
sures students’ levels of social-emotional well-being.This
is defined as the presence of positive emotions and
behaviours (e.g. ‘‘The student appears to be generally
happy and cheerful’’) and the absence of negative emotions
and behaviours (e.g. ‘‘The student appears to say ‘mean’
things to intentionally hurt someone else’’). Part 2 consists
of 28 items and measures students’ social-emotional
competence. Within Part 2, three clusters of items are
represented: Positive Self-Orientation, Positive Social
Orientation, and Positive Work Orientation. The Positive
Self-Orientation subscale measures resilience (in terms of
attitudes and coping skills). An example item is: ‘‘The
child appears to control his/her behaviour when he/she is
very angry and feels like lashing out’’. The Positive Social
Orientation subscale measures social skills and values.An
example item is: ‘‘The child appears to value doing things
to help others.’’ The Positive Work Orientation subscale
measures work management and engagement skills.An
example item is: ‘‘The child appears to raise his/her hand to
answer a difficult question even when unsure if the answer
is correct.’’ The ACER Well-being Surveys (Teacher
Forms; Student Forms) have been validated from data

provided by over 6,000 teachers. Cronbach alpha reliabil-
ities in the order of 0.9 are reported (Bernard et al. 2007).
Validity of the survey has been determined through the use
of Rasch measurement methods (Bond and Fox 2007),
including item characteristic curves confirming that all
items on the survey measured the construct of well-being
of students and that the requirements of measurement are
satisfactorily met (Bernard et al. 2007).
The second questionnaire used was the Social Skills
Rating System—Teacher Form (SSRS-T) (Gresham and
Elliot 1990). This survey consists of 57 items divided into
three scales: Social Skills, Problem Behaviours and Aca-
demic Competence. According to the manual, the SSRS-T
has demonstrated high internal consistency and test–retest
reliability as well as adequate content and criterion valid-
ity. On the Social Skills scale (30 items) teachers rate how
often the student engages in each of the behaviours
described (e.g. ‘‘Introduces herself or himself to new
people without being told’’) from 0 (never) to 2 (very
often). Within the Social Skills scale there are also three
subscales, each consisting of 10 items: Co-operation,
Assertion, and Self-control. Teachers can also rate how
important each of these behaviours are for success in their
classroom from 0 (not important) to 2 (critical); however,
these ratings were judged as unnecessary in this study, and
were therefore not used. On the Problem Behaviours scale
(18 items) teachers rate how often the student engages in
each of the behaviours described (e.g. ‘‘argues with oth-
ers’’) from 0 (never) to 2 (very often). Within the Problem
Behaviours scale there are also three subscales, each con-
sisting of six items: Externalizing Behaviours,Internaliz-
ing Behaviours, and Hyperactivity. Finally, on the
Academic Competence scale (9 items) teachers rate how
the student’s levels of academic achievement compares to
other students in the class, from 0 (in the lowest 10%) to 5
(in the highest 10%). This scale was judged to be inap-
propriate for investigating mean group changes over time
and was, therefore, not used in this study.
As an alternative to the SSRS-T Academic Competence
scale, teachers were asked to report each student’s Inde-
pendent Text Reading Level at each time point. These
reading levels range from 0 (lowest) to 28 (highest), and
indicate the text difficulty level that the child can read
independently. The school reported that they expect stu-
dents to achieve Level 5 by the end of Prep, Level 20 by
the end of Grade 1, and Level 28 by the end of Grade 2.
Treatment Integrity
A classroom observation form was developed to investigate
program implementation integrity. This observer rating
form measured the extent to which teachers: followed the
YCDI lesson plans, were well-prepared and presented the
lessons as intended in the lesson plan, provided helpful
feedback to children, checked understanding with indi-
vidual children and presented the lesson in a positive and
enthusiastic fashion. Each teacher’s behaviours in each of
these areas was rated on a three-point scale from 1 (=not at
all) to 3 (=very much). The first author completed this form
twice for each YCDI teacher while observing the lessons
being presented.
Education Program
Teachers in the YCDI groups were trained in the use of the
following different components of the YCDI Early Child-
hood program. (1) The YCDI Social and Emotional
Learning Curriculum consisting of many structured lessons
containing activities that presented the emotional, behav-
ioural and attitudinal (self-talk) characteristics of confi-
dence, persistence, organisation and emotional resilience.
The activities incorporate the following explicit and direct
instructional practices: operationally defining social and
emotional skills in terms of concrete, observable behav-
iours that are described, modelled and role played, com-
munication of behaviour-specific feedback when children
display social and emotional learning behaviour, explicit
teaching (e.g., present new material in small steps, giving
clear and detailed instructions and explanations, providing
active practice for all learners, asking questions to check
for understanding, guiding learners during initial practice,
continued practice until learners are independent and
confident) and explicit teaching of self-talk; (2) use of hand
puppets to explain and illustrate ideas to young children
(e.g., Connie Confidence, Pete Persistence) (3) four songs
for children to sing that contain lyrics supporting what
young children learn in their lessons (e.g., ‘‘I’m Connie
Confidence and I like to take a chance, I tell myself I can
do it.’’) (4) multiple colourful posters of each character
(Connie Confidence, Pete Persistence, Oscar Organisation
and Ricky Resilience) that illustrate each character learning
the relevant behaviours and positive self-talk, and (5) good
classroom practices for establishing a social and emotional
learning environment (e.g., select examples of stories from
young children’s literature to read aloud and songs to sing
that portray a character demonstrating one or more social
and emotional learning skills, daily reminders and reflec-
tions, wall displays).
Procedure
One Preparatory and one grade 1 class were randomly
selected to implement the program (the YCDI classes) and
the other two classes served as a comparison group (the
non-YCDI classes). All four teachers completed both the
two questionnaires and the reading levels for each student.

Following this, the teachers from the YCDI classes were
trained in the implementation of the You Can Do It! Early
Childhood Education Program, by Professor Michael E.
Bernard, the Founder of YCDI, during a 2-h professional
development session at the school. The YCDI teachers then
began implementing the program in their classrooms at the
end of Term 2. This involved running approximately three
20-min YCDI lessons per week, as well as supporting the
students to practice the YCDI skills they were learning on
an ongoing basis throughout the school day.
Preparatory and grade 1 teachers presenting YCDI spent
2 weeks (approximately six lessons) providing direct
instruction in four social and emotional competencies:
confidence, persistence, organisation and emotional resil-
ience. It is important to note that because the two YCDI
teachers independently selected the YCDI lessons that they
delivered to their classes, the Prep and Grade 1 students did
not receive exactly the same program content.
Data Analysis
The data collected from the two questionnaires, as well as
the teacher-reported student reading levels, were entered
into the statistical package SPSS v.15 for analysis. The
WBS was recoded from a four-point scale to a five-point
scale, and any missing data was estimated using the
Expectation Maximization (EM) method. Based on the
internal consistency and normality of each scale of the
WBS and SSRS-T, five variables (scales) were selected for
further analysis. Two variables were chosen to measure
social-emotional well-being: Positive Social-Emotional
Well-being (all items from Part 1 of the WBS) and Total
Problem Behaviours (items 31–48 from the SSRS-T). Two
variables were chosen to measure social-emotional com-
petence: Total Social-Emotional Competence (all items
from Part 2 of the WBS) and Total Social Skills (items
1–30 from the SSRS-T). Reading Level was retained as the
measure of academic achievement.
Results
Treatment Integrity
The ratings of each YCDI teacher on the classroom obser-
vation form indicated that both YCDI teachers were well
prepared, provided helpful comments to children, checked
that individual children understood the lessons, and pre-
sented the lessons with enthusiasm. However, neither tea-
cher closely followed the scripted lesson plans in the YCDI
curriculum manual. The Prep teacher covered the general
content of the lesson plan during both observations, but
significantly modified the lesson plans contained in the
YCDI curriculum manual. On both occasions that the Grade
1 teacher was observed, she presented activities from the
curriculum as well as additional ones that she had created
based on the lessons in the YCDI curriculum program. For
example, during the first observation she read the children a
story about a character that demonstrated persistence and
then gave them a worksheet that she had adapted from an
YCDI lesson, which asked questions about how the char-
acter had shown persistence. As the Grade 1 YCDI class
showed more robust improvements than the Prep YCDI
class, it may be the case that the impact of the YCDI
intervention is greater when teachers rely on the explicit
teaching guidance contained in the YCDI curriculum con-
cerning how the content of the lesson should be delivered.
Impact of Treatment
As will be seen below, the data was examined in two ways.
First, the impact of YCDI across all social-emotional
measures (called the combined variable) was examined
using a multivariate analysis of variance. The dependent
variables included in the combined variable included:
Positive Social-Emotional Well-being, Total Problem
Behavior, Total Social-Emotional Competence and Total
Social Skills. Second, the impact of YCDI on the separate
dependent measures including Reading Level was exam-
ined using an analysis of variance.
For both the MANOVA and ANOVA analyses, tests of
interactions enabled the determination to be made as to
whether YCDI produced greater gains over time for the
YCDI group of students. As well, tests of interaction
enabled a judgment to be made as to whether the impact of
YCDI over time was consistent or different for Prep and
Grade 1 classes.
Measures of Social-Emotional Well-being
and Social-Emotional Competence
A mixed within-between subjects MANOVA was carried
out in order to determine whether group (YCDI: non-YCDI
class) and grade (Prep; Grade 1) influenced the students’
levels of social-emotional well-being and competence. The
results indicated that there were significant multivariate
effects (Pillai’s F
4,92
=12487.40, p\0.01, partial g
2
=
0.99). Further interpretation revealed that there were no
significant differences between the Prep and Grade 1 stu-
dents on the combined dependent variable (Pillai’s F
4,92
=
0.82, ns, partial g
2
=0.03). However, there was a signifi-
cant difference between the YCDI and non-YCDI groups
(Pillai’s F
4,92
=6.93, p\0.01, partial g
2
=0.23), as well
as a significant interaction between grade and group (Pillai’s
F
4,92
=15.19, p\0.01, partial g
2
=0.40) on the combined
dependent variable.
Early Childhood Educ J (2012) 39:397–405 401

The MANOVA results also revealed that a significant
interaction between Time (pre-test; post-test) and group
(YCDI vs. non-YCDI class) had an effect on the combined
dependent variable (Pillai’s F
4,92
=14.69, p\0.01, par-
tial g
2
=0.39). When the results for the dependent vari-
ables were considered separately, analyses revealed that
this interaction had a significant effect on Positive Social-
Emotional Well-being (Pillai’s F
1,95
=18.52, p\0.01,
partial g
2
=0.16), Total Social-Emotional Competence
(Pillai’s F
1,95
=25.99, p\0.01, partial g
2
=0.22), and
Total Social Skills (Pillai’s F
1,95
=43.92, p\0.01, partial
g
2
=0.32). An inspection of the table of means indicates
that the YCDI classes made greater gains in these three
areas than the non-YCDI classes. However, the interaction
between time and group had no significant effect on Total
Problem Behaviors (Pillai’s F
1,95
=1.24, ns, partial
g
2
=0.013). This indicates that YCDI did not result in an
overall reduction in problem behaviors.
Furthermore, the MANOVA results also indicated that a
significant interaction between time (pre-test; post-test),
grade (Prep; Grade 1), and group (YCDI; non-YCDI) had an
effect on the combined dependent variable (Pillai’s F
4,92
=
6.84, p\0.01, partial g
2
=0.23). When each dependent
variable was analyzed separately the results revealed that
this interaction had a significant effect on Total Problem
Behaviors (Pillai’s F
1,95
=22.89, p\0.01, partial g
2
=
0.19) and Total Social Skills (Pillai’s F
1,95
=18.30,
p\0.01, partial g
2
=0.16). With regard to Total Problem
Behaviors, inspections of Table 1indicate that, while the
grade 1 YCDI class displayed a reduction in problem
behaviors, the preparatory YCDI class did not. The grade 1
non-YCDI class displayed an increase in problem behav-
iors, while the Prep non-YCDI class displayed a decrease.
With regard to Total Social Skills, inspection of Table 1
indicates that the Prep and Grade 1 YCDI classes both
displayed an increase in Total Social Skills over time;
however, the increase for the grade 1 students was larger
than that for the preparatory students. In addition, while the
preparatory non-YCDI class displayed similar levels of
Total Social Skills at Time 1 and Time 2, the grade 1 non-
YCDI class displayed a large decrease in Total Social Skills
over time.
There were a number of differences between the mean
scores of male and female students in both the YCDI and
non-YCDI classes on each of the dependent variables at both
time points. Males displayed higher levels of problem
behaviors, and lower levels of social-emotional well-being,
social-emotional competence, and social skills. Therefore, a
separate mixed within-between subjects MANOVA was
carried out in order to determine whether gender influenced
the effectiveness of YCDI. The results revealed that gender
had a significant main effect on the combined dependent
variable (Pillai’s F
4,92
=6.45, p\0.01, partial g
2
=0.22).
When each of the individual dependent variables was con-
sidered separately, the results indicated that males and
females differed significantly on all four measures: Positive
Social-Emotional Well-being (Pillai’s F
1,95
=13.71, p\
0.01, partial g
2
=0.13), Total Problem Behaviors (Pillai’s
F
1,95
=7.13, p\0.01, partial g
2
=0.07), Total Social-
Emotional Competence (Pillai’s F
1,95
=22.07, p\0.01,
partial g
2
=0.19), and Total Social Skills (Pillai’s F
1,95
=
22.35, p\0.01, partial g
2
=0.19). However, there were no
significant interactions between gender and time, gender and
group, or gender, group and time. These results indicate that
there were no differences in the effectiveness of YCDI
between males and females.

Reading Level
A mixed between-within subjects analysis of variance
(ANOVA) was conducted to explore the impact of YCDI
and grade on reading levels. There was a significant main
effect for time (Pillai’s F
1,95
=128.91, p[0.01, partial
g
2
=0.58), indicating that the students’ reading levels
increased over time. There was also a significant interac-
tion between time and grade on reading level (Pillai’s
F
1,95
=10.87, p=0.01, partial g
2
=0.10); however, the
interaction between time and group was non-significant
(Pillai’s F
1,95
=0.51, ns, partial g
2
=0.01), indicating that
gains in reading achievement were unrelated to YCDI. A
second mixed between-within subjects ANOVA was car-
ried out in order to explore the impact of YCDI and grade
on the reading levels of the 50% of children who had the
lowest reading levels at Time 1 (see Table 2). The results
of this ANOVA showed that an interaction between time
and group had a significant effect on reading levels (Pillai’s
F
1,49
=6.56, p\0.05, partial g
2
=0.12). This indicates
that YCDI had a positive effect on the reading achievement
of the less advanced readers in the study. There was also an
interaction between time, group, and grade that had a sig-
nificant effect on reading levels (Pillai’s F
1,49
=10.93,
p\0.01, partial g
2
=0.18). An examination of the group
means indicates that students in the grade 1 YCDI class
showed a greater gain than the grade 1 non-YCDI class, but
the Prep YCDI and non-YCDI classes showed similar
gains. This indicates that YCDI only had a positive effect
on the reading levels of the less advanced readers in
grade 1.
Discussion
Overall, the pattern of results are consistent with growing
research evidence that indicates that a social and emotional
learning program that includes explicit instruction in the
form of teacher-led lessons has a place in the early years
(e.g., Joseph and Strain 2003). While this study did not
isolate the relative effects of the curriculum lessons
employed from the modelling, reinforcement and general
conversations between teacher and young children that
supported the social and emotional learning skills taught in
the lessons, it would seem that the combined effects are
stronger than the effects of teachers responding in less
structured ways to children in particular ways surrounding
their social and emotional development.
The results of this study indicate that the You Can Do It!
Early Childhood Education Program was an effective way
of improving the social and emotional competence of
young children. Specifically, the students in the study who
received YCDI, delivered by their teachers as part of the
curriculum, displayed significantly greater gains in their
teacher-rated levels of social-emotional competence
(measured in terms of items associated with positive self-
orientation, positive other-orientation, and positive work-
orientation) and social skills (measured in terms of items
associated with co-operation, assertion, and self-control)
than the students who did not receive the program. Espe-
cially at Grade 1, the degree of improvement is substantial
and suggests the impact of the YCI program is likely to
have practical significance for young children. According
to their teachers’ ratings, after the YCDI program the
students in the YCDI classes were considerably more able
to manage their emotions, get along with others, and
engage in their academic learning, than the students in the
non-YCDI classes. These results support previous research
that has shown that YCDI (in its various formats) is an
effective way of teaching key social and emotional skills
(e.g., Bernard 2006,2008; Bernard and Walton 2011), as
well as more general research showing the effectiveness of
a range of SEL programs (e.g. Nelson et al. 2003; Payton
et al. 2008).
The results also indicated that that, although the prepa-
ratory and grade 1 students improved in their teacher-
reported levels of social skills, the grade 1 students showed
a greater improvement than the preparatory students.
However, there were no differences between males or
females, or between the students who spoke different first
languages, on the impact of YCDI on social-emotional
competence. This indicates that the program was equally
effective for male and female, and English and non-English
speaking students.

The students in the YCDI classes also displayed signif-
icantly greater gains in their levels of positive social-emo-
tional well-being (measured in terms of items associated
with the presence of positive emotions and behaviours, and
the absence of negative emotions and behaviours) after the
program than the students in the non-YCDI classes. Fur-
thermore, both YCDI classes showed similar increases in
positive social-emotional well-being, indicating that the
program was equally effective for the preparatory and grade
1 students. Among the non-YCDI classes, the preparatory
students made small gains in social-emotional well-being,
while the grade 1 students displayed a reduction in this area.
There were no differences between males or females, or
between the students who spoke different first languages, on
the impact of YCDI on positive social-emotional well-
being. These results further support and extend past
research (e.g., Bernard 2007) by indicating that teaching
key social and emotional skills, in the format of YCDI, was
an effective way of improving the social-emotional well-
being of the preparatory and grade 1 students in this study.
In contrast to the finding that YCDI was effective at
promoting an increase in positive social-emotional well-
being, there was no evidence that YCDI resulted in an
overall reduction in total problem behaviours (measured in
terms of externalising, internalising, and hyperactivity
problems). However, these results did differ between the
YCDI classes. Specifically, the grade 1 YCDI students did
display a significantly greater reduction in their levels of
problem behaviours than the grade 1 non-YCDI students,
while the preparatory YCDI students did not. This indicates
that the program was effective at reducing the problem
behaviours displayed by the grade 1 students, but not by the
Prep students.
In terms of the impact of YCDI on academic achievement,
the results of this study showed no significant differences in
reading levels between the YCDI and non-YCDI students
after the program. However, when the progress of the 50% of
students who displayed the lowest reading levels before the
program was investigated, the students from the YCDI
classes displayed greater gains in their levels of reading
achievement than the students in the non-YCDI classes. The
magnitude of improvement for the YCDI class was robust
exceeding two standard deviations suggesting that the YCDI
intervention had not only statistical but practical signifi-
cance. However, once again these results varied by grade
with only the grade 1 YCDI lower achievers displaying a
significantly greater gain in reading achievement relative to
their peers. These results provide some support for the third
hypothesis, by indicating that YCDI was an effective way of
improving the reading levels of low achievers.
The results also indicated that the program was equally
effective for children from a range of cultural backgrounds.
This is an important finding, given that 54% of the students
in the study did not speak English as their first language.
This finding is also important given that researchers have
argued that there is a need for further research into the
cultural relevance of various SEL programs (e.g. Humph-
ries and Keenan 2006).
Methodological Limitations
The first limitation is that the study was conducted in only
one school, meaning that it is not possible to generalise
these results to other schools, particularly those who have
students from different socio-economic or cultural back-
grounds. A second limitation of the study was that the
sample size was relatively small, with only 99 students and
four teachers participating. This meant that it was only
appropriate to investigate a small number of dependent
variables. Therefore, it was not possible to state whether
the YCDI students improved in particular areas of social-
emotional competence (e.g. resilience, academic engage-
ment, cooperation) or well-being (e.g. externalising or
internalising problems). A third limitation to this study was
the choice of measurements used to estimate the students’
levels of academic achievement. Independent text reading
levels were used, as they were easy for teachers to com-
plete and did not require the students to undergo any
additional assessment. However, this measure is only a
rating of the students’ ability to decode text. Therefore,
although some positive results were found for the effect of
YCDI on reading levels, it is not appropriate to state that
YCDI has a positive effect on students’ overall levels of
academic competence without further research. Another
limitation of the study was that the teachers knew which
group they were in (e.g., YCDI or non-YCDI) which could
have biased their ratings of their students. The final limi-
tation was that the results of this study are based only on
teacher-reported levels of social-emotional competence
and well-being. Although teacher reports are one way in
which to obtain information on students’ functioning, they
should ideally be supplemented by parent-reports and/or
direct observations.
It would be beneficial for future research to investigate
whether the benefits of the program are maintained in the
long term. Longitudinal research into the effectiveness of
other programs has shown that some do have long-term
benefit; however, these do tend to decrease over time
(Nelson et al. 2003; Payton et al. 2008).
Conclusions
In summary, the results of this study provided further
support for the view that social-emotional competence is
foundation for the achievement and well-being of young

children (Center on the Social Emotional Foundations for
Early Learning 2008). The results also support the findings
of a number of other researchers who have argued that, by
improving children’s levels of social-emotional compe-
tence through explicit instruction, it is possible to improve
their levels of social-emotional well-being and academic
achievement (e.g. Nelson et al. 2003; Payton et al. 2008).
Future research into the long-term benefits of the program,
as well as the conditions under which it is most effective,
would provide additional insight into the value of YCDI as
a pro-active universal mental health prevention program
for young children. It is suggested that, given the com-
plexity and difficulty of teaching social and emotional
skills effectively, early childhood educators (and young
children) can benefit from the use of explicit and direct
instructional practices contained in formal social and
emotional curriculum lessons.
