Abstract

The authors revised and validated the New Ecological Paradigm (NEP) Scale for use with upper elementary students. Researchers use the NEP Scale extensively with adults, but it was not designed for children. Interviews with 5th grade students helped the authors revise the NEP Scale for use with children. The authors spent 2 years validating the modified instrument with larger numbers of students. After analyzing their results, the authors suggest that a 3-dimensional modified NEP Scale for Children, with 10 instead of 15 items and revised wording, is appropriate for use with children aged 10-12 years.

KEYWORDS: earth education, environmental worldviews, New Ecological Paradigm Scale
rom the late 1960s onward, the growing recognition of the seriousness of environmental
problems led to hundreds of studies of environmental attitudes and beliefs. Yet, because
many of the studies contributing to this literature had not undergone a rigorous develop
-
ment process from a psychometric point of view, only a modest amount of knowledge accumulated
(Dunlap & Jones, 2002; Gray, 1985). Rather than conducting replications with well-established
measures, researchers in the majority of studies used instruments developed for a specific project,

providing little evidence of their validity and reliability (Gray; Leeming, Dwyer, & Bracken, 1995).
In a major review, Leeming, Dwyer, Porter, and Cobern (1993) examined 34 studies that assessed
changes in environmental attitudes, knowledge, and behavior. They reported finding scales with
limited use beyond the original study and little evidence regarding validity and reliability.
These problems are especially apparent in studying childrens environmental orientations because
few studies have used well-developed instruments. Of all the instruments reviewed by Gray (1985)
and by Dunlap and Jones (2002), not one was designed for children. Leeming et al. (1993) reviewed
several relevant studies but found only one, Armstrong and Impara (1991), that they felt was of high
quality. Leeming et al. (1995) encouraged more research on environmental attitudes and behavior of
children because “early attitudes and knowledge shape the later thinking of adolescents and adults
(p. 23), and empirical research in the past had underrepresented this population.
In our study, we present an adaptation of the New Ecological Paradigm (NEP) Scale for use
with upper elementary students. As an adaptation of the NEP, the most widely used instrument for
studying environmental orientation among adults, our measuring instrument should prove useful for
studying childrens environmental orientations.
Theoretical Perspective: From the Dominant Social Paradigm (DSP) to the NEP
Numerous early analysts of environmental problems argued that Americans commitment to
abundance, progress, prosperity, laissez faire, individualism, and property rights have contributed
to environmental problems and posed barriers to the effective solution of such problems (Caldwell,
1970; Campbell & Wade, 1972; Dunlap & Van Liere, 1978; Whisenhunt, 1974). Three decades
ago, Pirages and Ehrlich (1974) pointed out that a new worldview was beginning to challenge the
Dominant Social Paradigm (DSP) consisting of the traditional values, attitudes, and beliefs noted
above. This new social paradigm or worldview, called the New Environmental Paradigm (NEP) by
Dunlap and Van Liere (1978) and more recently the New Ecological Paradigm by Dunlap, Van
Liere, Mertig, & Jones (2000), challenges the DSP by rejecting the anthropocentric notion that
nature exists solely to serve human needs (Barbour, 1973; Commoner, 1971; Daly, 1973; Meadows,
Meadows, Randers, & Behrens, 1972). In addition to rejecting the idea that nature has no value
beyond human use, the NEP emphasizes that modern industrial societies are exceeding ecological
limits and disrupting ecosystems (Dunlap & Van Liere).
The new worldview has evolved from early concerns about specific environmental problems
and natural resources to recognizing that humans may be fundamentally altering the functioning
of the global ecosystem, with the result that unpredictable and irreversible changes may occur
(Dunlap et al. 2000). What many once viewed as discrete, local problems have evolved into global
problems with complex, synergistic causes and unpredictable, possibly irreversible effects. As a
result, researchers have made an observable turn toward studying public perceptions and aware-
ness of global ecological problems and the human–environment relationships that produce them
(Dunlap, 1998; Stern, 1992).
Recognition of the importance of examining the relationship between modern societies and the
environments that produced these problems led to the construction of the 12-item NEP Scale as
a means of measuring public acceptance of the emerging paradigm (Dunlap & Van Liere, 1978).
Since then, the NEP Scale has become the most widely used measure of environmental concern
(Stern, Dietz, & Guagnano, 1995), used in scores of studies, including a growing number outside
the United States (Bechtel, Verdugo, & Pinheiro, 1999; Schultz & Zelezny, 1999). Although Dunlap
and Van Liere found that the NEP Scale measured a single dimension, others have found that it
measures two, three, or even four dimensions (Bechtel et al.; Edgell & Nowell, 1989; Furman, 1998;
SUMMER 2007, VOL. 38, NO. 4 5
Gooch, 1995; Noe & Hammitt, 1992; Noe & Snow, 1989, 1990; Roberts & Bacon, 1997; Scott &
Willits, 1994; Shetzer, Stackman, & Moore, 1991).
Researchers recently revised and updated the NEP Scale, renaming it the New Ecological
Paradigm Scale (Dunlap et al., 2000). The revised version contains 15 items, three each designed to
tap five key facets of the NEP: (a) limits to growth, (b) anti-anthropocentrism, (c) fragility of natures
balance, (d) rejection of human exemptionalism, and (e) belief in eco-crisis. These facets did not
form distinct dimensions in the original study because Dunlap et al. found one primary dimension
reflecting endorsement of an ecological worldview. The authors suggest, however, that the number
of dimensions may vary for different populations and that “in many cases it will no doubt be more
appropriate to treat the NEP as multidimensional” (Dunlap et al., p. 436).
Purpose of Our Study
Both the original NEP Scale (Dunlap & Van Liere, 1978) and the revised scale (Dunlap et al.,
2000) were designed for use with adults, but many environmental learning programs are designed
for children. Assessing environmental worldviews during childhood is of great interest to both those
offering such programs and researchers investigating the development of these worldviews.
Recently, researchers have developed new instruments designed to measure childrens environ-
mental worldviews, most notably the Childrens Attitudes Toward the Environment Scale (CATES;
Musser & Malkus, 1994) and the Childrens Environmental Attitude and Knowledge Scale
(CHEAKS; Leeming et al., 1995). CATES has not been widely used and employs an awkward
bipolar answer format, whereas CHEAKS assesses attitudes toward environmental issues through
both verbal commitment and self-reported actual behaviors. These instruments measure different
dimensions than NEP Scale.
We designed our study to determine if the revised NEP Scale (Dunlap et al., 2000) was suitable
for use with children ages 10–12 years and, if so, what modifications were necessary for use with this
age group. Our study also investigates whether the belief systems of children, as measured by the
NEP, is unidimensional or multidimensional. If the NEP Scale were applicable to children, research-
ers could (a) investigate childrens environmental worldviews and compare childrens worldviews
with those of adults, using a comparable measure and (b) study how worldviews change as children
become adults.
Method
Revision: Year 1
During the revision phase, from February to April 2003, we examined childrens comprehension
of the NEP Scale through interviews with 30 fifth-grade students (17 girls, 13 boys) from a school
in Pennsylvania, who were participants in Earthkeepers, an earth education program (Van Matre &
Johnson, 1988). Following our first interview with 13 students, which focused on the vocabulary in
the NEP Scale, we revised most of the items to make them more child friendly without changing
their meaning. Next, we used the NEP Scale with the revised items in interviews with 17 other fifth
graders, checking again for understanding of vocabulary but adding a focus on comprehension of
the meaning of the items. On the basis of those interviews, we further revised a few scale items and
tentatively constructed the NEP Scale for Children.
Finally, 54 fifth-grade students (32 girls, 22 boys) from two schools in Arizona and Pennsylvania
completed the revised scale as a pilot test. The students from Arizona were primarily Caucasian and
Hispanic whereas the students from Pennsylvania were mainly Causcasian. The tentative NEP Scale
6 THE JOURNAL OF ENVIRONMENTAL EDUCATION
for Children contained 15 items and the same 5-point Likert-type scoring system used in the adult
NEP Scale, with responses ranging from 1 (strongly disagree) to 5 (strongly agree). We reversed the
scoring for negatively worded items: 1 (strongly agree) to 5 (strongly disagree). The total scale score
ranged from a possible low of 15 (endorsement of the DSP) to a high of 75 (endorsement of the
NEP). The midpoint score of 45 can be arbitrarily interpreted as neutrality with regard to the two
competing worldviews.
Validation: Year 2
The participants in the first year of the validation phase of the study (September 2003 to
April 2004) were 672 fourth-, fifth-, and sixth-grade students from 23 schools in Louisiana and
Pennsylvania (52% girls, 48% boys). Students from Louisiana were mostly African American and
Caucasian, and students from Pennsylvania were mostly Caucasian. The students had participated
in either Earthkeepers (Van Matre & Johnson, 1988) or Sunship Earth (Van Matre, 1979), two
earth education programs that were part of their schools curriculum. The schools served students
of low- to middle-income levels. Both programs focus on encouraging participants to develop an
understanding of ecological concepts, build positive feelings for the natural world, and change their
environmental behaviors. Because the authors of the programs designed them to affect students
worldviews and feelings about the earth, they are appropriate for the purpose of this study. The stu-
dents completed the NEP Scale for Children as a pretest 1 week before they began the earth educa-
tion programs and as a posttest approximately 1 month after completing the programs.
We made a small change in the scale from Year 1, adding a Do not understand response to the
Likert-type scale to enable us to further detect problematic items. At the end of Year 2, we randomly
split the data in two, using one half for exploratory factor analysis (EFA; principal-components
analysis with varimax rotation) and the other half for confirmatory factor analysis (CFA; Pedhazur
& Schmelkin, 1991; Tabachnick & Fidell, 1996).
Validation: Year 3
In Year 3 (September 2004 to April 2005), on the basis of the second-year students’ responses, we
slightly revised the NEP Scale for Children one last time. We eliminated items that received a high
rate of the response Do not understand in Year 2. The 515 fourth-, fifth-, and sixth-grade students
(53% girls, 47% boys) involved in the third-year data collection came from the same schools in
Louisiana, Pennsylvania, and Arizona and had participated in either Earthkeepers or Sunship Earth.
Using the entire sample, we ran a second CFA to test how well Year 3 data fit the Year 2 model. We
also performed a paired sample t-test analysis with the 186 students who participated in the Sunship
Earth program
1
to validate the scale for its sensitivity to detecting change in childrens environmental
worldviews as a result of program participation.
Results
Revision: Year 1
During the first set of interviews, we identified 36 words as problematic for most of the students.
We replaced those words with easier and more familiar synonyms or short phrases in 13 of the 15
items. During the second set of interviews, only five additional words appeared to be problematic,
and 3 of the 17 students had comprehension problems with two items. After a researcher read those
items aloud, the students seemed to understand them, suggesting that the problem was in reading
rather than understanding. We further revised those two items before including them in the tentative
NEP Scale for Children.

EFA. Using a random half (n = 336) of the Year 2 sample, an unconstrained EFA initially revealed
five factors with Eigenvalues greater than 1.0, explaining 53.68% of the variance. However, several
items loaded almost equally on two different factors. We ran further analyses with different items
deleted each time. The best solution appeared to be one with 11 of the original 15 items arranged
in three factors, explaining 48.6% of the variance (see Table 1). We named the three factors Rights
of Nature, Eco-Crisis, and Human Exemptionalism (factors proposed by Dunlap and colleagues;
Dunlap & Van Liere, 1978; Dunlap et al., 2000), because a majority of the items on each dimen-
sion clearly reflected these facets of an ecological worldview. However, each of the three factors also
includes one item that the NEP authors intended as an indicator of a different facet.
CFA. We conducted a structural equation model (SEM) using AMOS software with the second half
(n = 336) of the sample to test the three-factor, 11-item model resulting from the EFA. In SEM, a
researcher posits a theoretical model, in this case on the basis of results of the EFA, and runs an analy-
sis to see how well the data fit the proposed model. In our study, the data were a good fit to the model
(see Figure 1). Goodness of Fit Index (GFI = .96), Adjusted Goodness of Fit Index (AGFI = .93), and
Comparative Fit Index (CFI = .90) were at or above the frequently recommended minimum level
of .90. Root Mean Square of Approximation (RMSEA = .05) is better than the often-recommended

level of .10 and at the level of .05 suggested by others (e.g., Hu & Bentler, 1999). The results thus
confirm the factor structure revealed in the EFA analysis (see Table 1).
We also examined values indicating the strength of the relationships shown in the model. First,
the values associated with items constituting each of the three factors indicate how well the items
within a factor relate to each other. As shown in Figure 1, items within each of the factors have
parameter estimates in similar ranges. The exception is in the Eco-Crisis factor, in which Item
1 has a parameter estimate that is substantially lower than the others in that factor. Second, the
parameter estimates for the relationships among the three factors show how well the three factors
fit together. In this case, Human Exemptionalism has a substantially lower value than have either
of the other two factors.
Because the original NEP authors suggested that for an adult sample a one-factor model is best
(Dunlap et al., 2000), we also tested a unidimensional model structure. The results, GFI (.91), AGFI
(.87), CFI (.64), and RMSEA (.09), were not as good as the results of the three-factor model. Thus,
it appears that the three-factor model is more appropriate for these students. The fit for the unidi-
mensional model is not greatly different, however, and it was clear that the model could be improved.
Thus, further testing in Year 3 seemed warranted.

indicating that it was difficult for some children to grasp. Table 2 contains the response frequencies
in Year 3 for each of the remaining 10 items (renumbered from 1 to 10).
A CFA with the whole sample (N = 515) in Year 3 revealed a good fit of the data to the Year 2 CFA
model: GFI = .96, AGFI = .93, CFI = .75, RMSEA = .066 (see Figure 2). The results provided fur-
ther evidence that the three-factor structure offers a good solution for the NEP Scale for Children.
Examination of parameter estimates revealed that the three factors fit together better than they
did in Year 2. All three values are between .86 and 1.0, indicating strong relationships. For the
most part, the items within each factor also have strong parameter estimates, although one item in
Rights of Nature and one in Eco-Crisis does not fit as strongly as do the others. The factor Human
Exemptionalism has items with low parameter estimates, indicating that its items do not fit together
as strongly as do those in the other two factors.
In Year 3, the unidimensional model also fits the data well. Model fit statistics are in the same
range as those for the three-factor structure: GFI = .94, AGFI = .90, CFI = .83, RMSEA = .085.
Thus, it appears that, for this student sample, we can treat the NEP Scale for Children as three-
dimensional, giving each student three separate scores, or as a single measure, giving each student
an overall NEP score.

program provided evidence of the scales effectiveness in detecting changes in students environmental

scores using average mean scores (on the 5-point scale) across relevant items: Rights of Nature (1, 4, and
7), Eco-Crisis (2, 5, 8, and 10), and Human Exemptionalism (3, 6, and 9). Items 3, 6, 7, and 9 were
reverse scored (i.e., strongly agree = 1 instead of 5). Before performing the statistical analysis, we exam-
ined the data for normal distribution because distortion violates the assumption on which the t test is
based. None of the variables had a distribution far enough from normal for a violation to occur.

Despite that the majority of students attending the program started with pro-ecological scores on two
of the three factors, Rights of Nature and Eco-Crisis, their worldviews changed significantly toward a
more pro-ecological perspective after the program (see Table 3). We loosely interpreted the increase in
their scores on the factor of Human Exemptionalism, from below the midpoint to above it, as reflecting
a shift from a slightly anthropocentric to a slightly ecocentric perspective. Their total scores for the NEP
Scale for Children also increased significantly. Although modest in magnitude, all of these changes were
statistically significant, as shown in the effect size data in Table 3.
Other studies have evaluated the effect of the Sunship Earth program, but all used study-specific
questionnaires (Bires, Johnson, & McFadden, 1982; Keen, 1991; Mulligan, 1989; Payne, 1981; van
Wissen, 1992). Those researchers’ results have been mixed, with most finding little or no change in
attitude. None of the instruments used in those studies, however, were developed using a theoreti-
cally sound construct of attitude or worldview. The NEP Scale for Children, designed specifically to
measure endorsement of an ecological worldview, revealed that the program produced a significant
effect on childrens worldviews. Our data clearly indicate that participation in the Sunship Earth
program produces a shift toward a more pro-ecological worldview among children.
Conclusion
Our results suggest that the NEP Scale for Children, with 10 instead of 15 items and revised word-
ing, is appropriate for use with children ages 10–12 years. We further found that the instrument mea-
sures three interrelated dimensions of the New Ecological Paradigm: Rights of Nature, Eco-Crisis, and
Human Exemptionalism. Dunlap et al. (2000) proposed all three of these dimensions in the design
of the revised NEP Scale. We also found it possible to treat the scale as a unidimensional measure
providing one overall score on the anthropocentric (DSP, low score) to ecocentric (NEP, high score)
continuum, after reverse scoring the negatively worded items of the scale (items 3, 6, 7, and 9).
It is not surprising that the change produced by participation in the Sunship Earth program was
not large. Before participating in the program, the students held pro-environmental (or pro-ecologi-
cal) views on two of the three factors as indicated by the pretest scores, leaving little room for change
in the pro-ecological direction. Anticipation of participation in the program or classroom activities
in preparation for it could have presensitized students toward nature (Bogner, 1998; Howie, 1974).
On the other hand, environmental worldviews are deeply rooted beliefs, and change in them appears
inevitably to be slow (Bogner). Consequently, for a 5-day intervention to produce statistically sig-
nificant effects is impressive. The finding is highly valuable because researchers have not conducted
comparable studies of potential changes in adult worldviews in response to educational programs.
We are currently using the NEP Scale for Children in studies of students participating in earth
education programs in Australia and other parts of the United States. Using the instrument with
larger numbers of students in a variety of locations will help determine the generalizability of the
NEP Scale for Children. Additional administrations also allow for further testing of the three-
dimensional model that emerged in this study. In addition, the NEP Scale for Children can be
a useful instrument for evaluating the ability of environmental learning programs to produce
changes in environmental worldviews. We are using the NEP Scale for Children along with
other instruments, observations, and interviews with children and their parents to investigate the
relationships among environmental worldviews, ecological understandings, and environmental
actions and how education affects those variables.
Despite the positive results of the study, we must use caution when interpreting the findings. The results
may not apply to children in other locations. We cannot generalize our results until we and other research-
ers have conducted further studies with children from other backgrounds and in other locations.

12 THE JOURNAL OF ENVIRONMENTAL EDUCATION
For more than a quarter of a century, researchers have successfully used the New Environmental
Paradigm Scale and the more recent version, the New Ecological Paradigm Scale, to investigate adult
environmental worldviews. The NEP Scale for Children allows for similar investigations of how
childrens environmental worldviews develop, how they change as a result of new experiences or edu-
cational programs, and how the environmental worldviews of children from different socioeconomic
or cultural backgrounds compare. These are important questions, and the NEP Scale for Children
can play an important role in answering them.
NOTE
1. For pre- and posttest comparison, we selected students who had participated in the Sunship Earth program. Because
Sunship Earth is a longer residential program than Earthkeepers, participation in Sunship Earth is more likely to affect
worldviews (Bogner, 1998).

... Analysis of variance revealed that children from rural areas have a more ecocentric worldview than those from urban areas. While gender has been identified as a possible determinant of ecological views in studies among children (Evans et al., 2007;Manoli et al., 2007), differences in EO between boys and girls have not yet been observed. Widegren (1998) examined the relationship between educational attainment and income with environmental orientation, finding little effect on pro-environmental attitudes (pro-EAs) and willingness to pay. ...

This study initially conducted a systematic literature review to examine gender differences in environmental orientation (EO) using the New Ecological Paradigm (NEP) scale. Following PRISMA guidelines, 38 studies were selected from a total of 168, providing a comprehensive overview of the existing research on the topic. Based on the insights gained from the review, a large sample survey was then conducted to explore further the differences in EO between male and female consumers. The results were compared with previous studies employing similar methodologies. The central research question is: Does gender identity influence EO as measured by the New Ecological Paradigm (NEP) scale? The NEP scale is a well-established instrument for assessing environmental attitudes. The significance of this topic lies in the potential impact of differing attitudes among gender groups on the effectiveness of communication and comprehension. Understanding these differences is crucial for developing strategies for sustainable development through targeted and effective messaging. Our findings indicate that women exhibit a higher NEP orientation, suggesting they are more aware of environmental concerns than men. The systematic review also confirmed this trend, with the majority of studies reporting higher environmental awareness among women. Additionally, women demonstrate greater awareness of related problems and a higher willingness to change their behavior to reduce their environmental impact. In contrast, men’s attitudes are more varied, reflecting a broader diversity of opinions within this group.
... Validation Constructs. Environmental Concern was measured with a short version of the New Environmental Paradigm (NEP) scale (Manoli et al., 2007). The scale included ten items (e.g., 'people are treating nature badly') on a 5-point Likert scale. ...

The perceived sustainability of food plays a significant role in young consumers' eating behaviors. While it is highly relevant to investigate these sustainability perceptions, the available measures are limited. Previous research has mostly relied on single-item measurements that only allow a surface-level understanding of food sustainability perceptions. Therefore, this research aims to provide researchers with a scale to measure perceptions of environmental food sustainability, addressing the need for such a measurement tool. We used a mixed-methods approach to develop and validate the Perceived Environmental Sustainability (PENSUS) Scale for Food and Drinks. Items were generated and refined based on expert interviews and focus group discussions with young consumers (i.e., 12 – 25 years) (Phase 1). The structure of the scale was explored in two online surveys (Phase 2), and subsequently confirmed with confirmatory factor analyses in four online experiments (Phase 3). This process resulted in a 10-item version of the PENSUS scale, designed to measure perceptions of 1) production & processing, 2) packaging and 3) transport. The scale serves as a concise, reliable tool to measure young consumers' environmental sustainability perceptions.
... Since the beginning of the current millennium, interest in this construct has increased and various scales have been developed. They can be divided into two clusters: (i) unidimensional scales, i.e., the Children Attitudes Toward Environment Scale [52], the New Ecological Paradigm Scale [16], the Environmental Attitudes Short Scale [46], the New Ecological Paradigm Scale for Children [53], the Environmental Attitudes Scale [40], the Environmental Attitudes Scale [42], and the Attitudes toward Consumption-related Environmental Issues Scale [41], and (ii) multidimensional scales, i.e., the Two Major Environmental Values Scale [54] and the Environmental Attitudes Scale [55]. We can also divide these scales by length into two clusters: (i) short scales composed of ten items or less, like the Environmental Attitudes Scale [40] and the Environmental Attitudes Short Scale [46], and (ii) mediumlong scales with more than ten items, like the Environmental Attitudes Scale [55] and the Environmental Attitudes Scale [42]. ...

In recent decades, the scientific literature has increasingly linked specific human activities to various environmental issues, with climate change being a prominent concern. Environmental Psychology has thus placed its focus on comprehending the dynamics driving Pro-environmental Behaviors (PEBs). Research spotlights two crucial constructs fueling PEBs: Connectedness to Nature (CTN) and Environmental Attitudes (EAs). In the absence of a well-established model, this systematic review strives to advance the understanding of their compound relationship. Following PRISMA guidelines, a comprehensive literature search across Google Scholar, PsycInfo, PsycArticles, PubMed, Science Direct, Sociological Abstracts, and Academic Search Complete databases produced 2658 records. Of these records, only 19 studies met the eligibility criteria after passing the abstract selection phase and were consequently included in this systematic review. Our analysis revealed that CTN and EAs are distinct constructs but showed moderate-to-high correlations. This review posits two hypotheses: (i) CTN may function as a dimension of identity and serve as an EA antecedent and (ii) CTN could be a combination of both implicit and explicit EAs. Subsequently, an interaction model is devised to comprehensively elucidate PEB dynamics and guide effective interventions for their promotion in the context of sustainability.
... In addition, it seems to be worthwhile to examine the associations of PIO with other concepts of nature connectedness, including other facets of nature-identity connection in the analysis, and with pro-environmental beliefs measured by a version of the New Ecological Paradigm (NEP) Scale (Dunlap et al., 2000). What makes the latter particularly significant is that in our other research projects justifying the multidimensionality of the Hungariantranslated version of the NEP Scale for Children (Manoli et al., 2007), one of the three subscales of the questionnaire (called Questioning of Human Intervention) showed negative associations with PEB and nature relatedness . Based on these results, we argued that the original interpretations of this items of subscale, intended by NEP authors to be anti-environmental, have changed over the past decades as a result of the emerging emphasis on environmental protection: the human intervention is already not interpreted as clearly harmful, and the human control over their activities is inseparably connected with the control and rule over nature. ...

In the frame of the inner–outer (personal–social) dichotomy in theories of social or personality psychology, it is argued in this study that, as a new approach, it is reasonable to examine individual differences in tending to orient toward another outer facet, not just social, i.e., the surrounding socio-physical environment while defining the self-concept—first performing it at the level of place-scaled meaningful settings, thus, interpreting place identity in the context of identity orientations. The present research aimed to theoretically and methodologically support a new concept based on this approach: place identity orientation (PIO). For the latter purpose, the development process of the questionnaire measuring it, which was based on supplementing the Aspects of Identity Questionnaire (AIQ-IV), was completed. In addition, the new construct was validated based on the relationships discussed in literature between place identity, connectedness with a larger-scaled environment, i.e., nature, and pro-environmental behavior (PEB), moreover, identity orientations and behavior. In our first scanning step of validating PIO, a partial mediation between PIO and PEB through nature connectedness was found among 1,281 adults. It suggests that the relative importance of the relationship with places in self-definition has a distinct role in addition to nature connectedness in behaving pro-environmentally. Limitations and future research directions (e.g., using PIO to examine people–environment fit in several settings) are also discussed.
... A 15-item version [44] was used as the parents' questionnaire. The NEP for Children [48], a 10-item scale adapted specifically for children from the original scale, was used in the children's questionnaire. In both questionnaires, respondents rated their agreement on a five-point Likert scale (1: Strongly disagree to 5: Strongly agree). ...

Decision-making within families considerably affects daily pro-environmental practices. While parental influence on children is known, the influence of children on environmental choices within families has yet to be thoroughly investigated, particularly in Asia. There are almost no reports regarding parent–child bidirectional transmissions in terms of environmental attitudes, psychological barriers, and pro-environmental behaviors (PEBs) in the Asian context. This study aimed to examine the parent–child bidirectional transmissions of environmental attitudes, psychological barriers, and PEBs in an Asian context, specifically in Japan and China. A total of 815 parent–child pairs (children ages 9–18) were recruited from Japan and China to participate in online questionnaire surveys. Regression analysis and structural equation modeling based on the actor–partner independence model revealed a bidirectional within-family socialization process of environmental attitudes, psychological barriers, and PEBs in the two countries. Children can transfer environmental knowledge and practices to their parents, which has been underestimated in the literature, particularly in Asia. Furthermore, our results suggest that Chinese children have more potential to act as catalysts in their family’s sustainable shift than Japanese children, given their substantial influence on family decision-making. The potential role of children in transmitting pro-environmental choices to their parents is also discussed.

This paper presents the findings of a study aimed at exploring teachers’ perspectives on environmental education for students in the first to fourth grades of primary school. The issue of environmental education for primary school students has gained significant attention in recent decades and is now seen as an educational necessity. The study’s objectives focus on understanding teachers’ views on the importance of teaching environmental topics in the first cycle of primary education and evaluating the school’s ability to support such teaching. The research was conducted through a survey involving 455 teachers from thirty-five primary schools across eight cities in the Republic of Serbia, using a questionnaire designed specifically for this study. The questionnaire featured a series of questions and rating scales based on a five-point Likert scale. Although there are some differences in respondents’ opinions based on factors such as work experience, school location, and the number of environmental seminars attended, the data suggest that teachers generally have positive views on the importance of including environmental topics in the first cycle of primary education. They also express favorable opinions about the conditions necessary to achieve the goals of environmental education in their schools. Teachers recognize the importance of studying environmental topics, not only for gaining knowledge, skills, and experiences but also for fostering students’ environmental awareness. The capacity of schools to support environmental education is most strongly influenced by extracurricular activities and various educational programs. This research highlights the crucial role of primary schools in meeting the goals of environmental education and lays the groundwork for further studies in this area, particularly focusing on teachers’ professional development and the acquisition of environmental competencies.

Dunlap and Van Liere's New Environmental Paradigm (NEP) Scale, published in 1978, has become a widely used measure of proenvironmental orientation. This article develops a revised NEP Scale designed to improve upon the original one in several respects: ( 1 ) It taps a wider range of facets of an ecological worldview, ( 2 ) It offers a balanced set of pro- and anti-NEP items, and ( 3 ) It avoids outmoded terminology. The new scale, termed the New Ecological Paradigm Scale, consists of 15 items. Results of a 1990 Washington State survey suggest that the items can be treated as an internally consistent summated rating scale and also indicate a modest growth in pro-NEP responses among Washington residents over the 14 years since the original study.

This volume fills the void created by the lack of a book-length, critical, and systematic treatment of ecological attitudes and behaviors. It emphasizes psychometrics and experimentation within a broad behavioral-cognitive framework focused on the natural world. Gray summarizes and integrates existing research and reviews major alternative approaches to measuring ecological attitudes, while presenting his own ecological attitude domain model. Russell Weigel and Richard Borden provide state-of-the-art reviews of the research on the relationship between ecological attitudes and actions and on the linkage between personality and ecological concern. Gray himself integrates the theoretical perspectives of social psychologists Milton Rokeach and Martin Fishbein in his construction of a paradigm for ecological change. Using this as background, he reviews existing behavioral studies, differentiating between those that rely on information and those that use reinforcement to produce a desired change in behavior. Finally, he suggests that the key to large-scale change is the creation of a true environmental ethic in our society.

The influence of the earth education program, Sunship Earth, on ecological knowledge and environmental attitudes was examined. It was found that students who attended the Sunship Earth program increased their ecological knowledge significantly. Participation in the Sunship Earth program did not result in more positive environmental attitudes. Part of the success of the Sunship Earth program is attributed to the setting in which it occurs and the techniques used to develop ecological concepts. The need for more opportunities for teachers to develop skills in environmental education and to participate in environmental education curriculum development that would link extension education more firmly to the school curriculum is discussed.
