ABSTRACT To examine the long-term effects of an intervention combining teacher training, parent education, and social competence training for children during the elementary grades on adolescent health-risk behaviors at age 18 years.
Nonrandomized controlled trial with follow-up 6 years after intervention.
Public elementary schools serving high-crime areas in Seattle, Wash.
Of the fifth-grade students enrolled in participating schools, 643 (76%) were given written parental consent for the longitudinal study and 598 (93%) were followed up and interviewed at age 18 years.
A full intervention provided in grades 1 through 6 of 5 days of in-service training for teachers each intervention year, developmentally appropriate parenting classes offered to parents when children were in grades 1 through 3 and 5 through 6, and developmentally adjusted social competence training for children in grades 1 and 6. A late intervention, provided in grades 5 and 6 only, paralleled the full intervention at these grades.
Self-reported violent and nonviolent crime, substance use, sexual activity, pregnancy, bonding to school, school achievement, grade repetition and school dropout, suspension and/or expulsion, and school misbehavior; delinquency charges from court records; grade point average; California Achievement Test scores: and disciplinary action reports from school records.
Fewer students receiving full intervention than control students reported violent delinquent acts (48.3% vs 59.7%; P=.04), heavy drinking (15.4% vs 25.6%; P=.04), sexual intercourse (72.1% vs 83.0%; P=.02), having multiple sex partners (49.7% vs 61.5%; P=.04), and pregnancy or causing pregnancy (17.1% vs 26.4%; P=.06) by age 18 years. The full intervention student group reported more commitment (P=.03) and attachment (P=.006) to school, better academic achievement (P=.01), and less school misbehavior (P=.02) than control students. Late intervention in grades 5 and 6 only did not significantly affect health-risk behaviors in adolescence.
A package of interventions with teachers, parents, and children provided throughout the elementary grades can have enduring effects in reducing violent behavior, heavy drinking, and sexual intercourse by age 18 years among multiethnic urban children. Results are consistent with the theoretical model guiding the intervention and support efforts to reduce health-risk behaviors through universal interventions in selected communities or schools serving high-crime neighborhoods.

    • "Student disruptive and challenging behaviors are major concerns to teachers (Reinke et al. 2011). Considerable research has demonstrated that effective teacher classroom management strategies can reduce disruptive behavior (Hawkins et al. 1999; Kellam et al. 1998; Walker et al. 1995), and enhance academic achievement (Brophy 1996; Coladarci and Gage 1984), school readiness, and student's social competence (Webster-Stratton et al. 2008, 2004). Conversely, ineffective classroom management practices are associated with increased disruptive behavior, and negative academic, behavioral, and social outcomes for students (Ialongo et al. 2001; Kellam et al. 1998; National Research Council 2002).

    ABSTRACT: Despite the growing evidence base for the efficacy of preventive interventions, the level of implementation of these interventions in schools is often less than optimal. One promising approach to supporting teachers in implementation of interventions is the use of coaching. In this study, teachers were trained in a universal classroom management intervention and provided ongoing coaching. The association between the type and amount of coaching activities and teacher implementation of proactive classroom management over time were investigated. Results indicated that teachers who received more performance feedback had higher levels of implementation over time in comparison with teachers who received less feedback. In addition, a significant interaction between the amount of coaching a teacher received and his or her implementation of proactive classroom management was found. Increased implementation over time was observed for teachers with lower initial levels of implementation who received more coaching, whereas implementation decreased over time for teachers who received less coaching. The importance of coaching as a support system for enhancing implementation quality of classroom-based preventive interventions is discussed.

    • "More than half of the analysis sample (n = 359; 50.8%) came from low-income families (as indicated by their participation in the free school lunch program in Grades 5, 6, or 7). A portion of the sample was exposed to a multicomponent preventive intervention in elementary grades, consisting of teacher training, parenting classes, and social competence training for children (see Hawkins et al., 1999, for a description and analysis of the intervention and effects). Although differences in prevalences and means have been observed between intervention and control groups, prior analyses have shown few differences in the covariance structures of the groups (Abbott et al., 1991; Catalano et al., 1996; Huang et al., 2001).

    ABSTRACT: This study examined potential explanatory mechanisms linking childhood alcohol use onset and chronicity of adult alcohol dependence by testing the following three competing hypotheses: (1) a marker hypothesis, where early onset of alcohol use may be simply a marker for other factors that have been linked to both age at initiation and adult alcohol problems; (2) a compromised development hypothesis, where early alcohol initiation may interfere with adolescent development, which can lead to later alcohol problems; and (3) an increased substance use hypothesis, where early onset of alcohol use may lead to increased substance use in adolescence and, in turn, chronic alcohol dependence. Data came from a longitudinal community sample of 808 participants recruited at age 10 in 1985. Participants were followed through age 33 in 2008 with 92% retention. Childhood onset of alcohol use (before age 11), when compared with initiation during adolescence, predicted an increased chronicity of adult alcohol dependence, even after accounting for the hypothesized confounds from the marker hypothesis. In addition, adolescent compromised functioning did not mediate this relationship between early alcohol use and chronicity of adult dependence (Hypothesis 2), nor did adolescent substance use (Hypothesis 3). However, compromised functioning and substance use in adolescence predicted increased chronicity of alcohol dependence in young adulthood. Prevention efforts as early as the elementary grades should focus on delaying the onset of alcohol use and reducing substance use in adolescence as well as improving school functioning, reducing adolescent problem behaviors, and targeting adolescent peer networks.

    ABSTRACT: A systematic review was conducted to determine the extent to which an economic case has been made in high-income countries for investment in interventions to promote mental health and well-being. We focused on areas of interest to the DataPrev project: early years and parenting interventions, actions set in schools and workplaces and measures targeted at older people. Economic evaluations had to have some focus on promotion of mental health and well-being and/or primary prevention of poor mental health through health-related means. Studies preventing exacerbations in existing mental health problems were excluded, with the exception of support for parents with mental health problems, which might indirectly affect the mental health of their children. Overall 47 studies were identified. There was considerable variability in their quality, with a variety of outcome measures and different perspectives: societal, public purse, employer or health system used, making policy comparisons difficult. Caution must therefore be exercised in interpreting results, but the case for investment in parenting and health visitor-related programmes appears most strong, especially when impacts beyond the health sector are taken into account. In the workplace an economic return on investment in a number of comprehensive workplace health promotion programmes and stress management projects (largely in the USA) was reported, while group-based exercise and psychosocial interventions are of potential benefit to older people. Many gaps remain; a key first step would be to make more use of the existence evidence base on effectiveness and model mid- to long-term costs and benefits of action in different contexts and settings.
