In this 3-year prospective study, we tested the extent to which school-, practice-, and district-level variables predicted sustained implementation for schools in various stages of implementation of school-wide positive behavioral interventions and supports (SWPBIS) Tier 1 (universal) systems. Staff from 860 schools in 14 U.S. states completed a…

This study (a) presented a structural model for examining how parents' perceptions of their children's competence, exercise benefits, exercise barriers and neighbourhood safety influenced parental support and their children's physical activity (PA) and (b) examined the mediating effect of parental support on children's PA. Parents of 478 children…

Adolescence is a period of dramatic change that necessitates using skills and strengths to reduce physical aggression and increase happiness. This study examined the multiple facets of self-control skills in achieving both goals simultaneously, in a sample of 248 Arab adolescents in Israel. We conceptualized and tested a new multi-mediator model…

This study focused on the ability to experience a high ratio of positive to negative emotions in 807 Israeli adolescents aged 12 to 15 years (50% girls). While considering possible gender differences, we tested a model positing that adolescents' self-control skills would link to their positivity ratio and indirectly through perceived social…

Research in recent years indicates that schools, and in particular teaching practices, play an essential role in preventing bullying. This study's aim is to investigate the direct and indirect relationships between permissive and direct intervention teacher practices, school support and bullying. In a non-probabilistic way, 386 (58.1%) boys and…

Purpose: This paper aims to investigate mediating effects of employees' work engagement in the relationships between their personal resources (i.e. self-efficacy, organizational-based self-esteem and optimism) and turnover intention within Korean organizations. Design/methodology/approach: A total of 571 survey responses collected from Korean…

This longitudinal study examined the relationships among parental autonomy support, student intrinsic life goals (i.e. community feeling), student expectations for long-term educational attainment and later academic performance (measured by GPA) in 227 students in an ethnically and racially diverse high school. Hypotheses were tested with…

A critical aspect of intervention research is investigating the active ingredients that underlie intensive interventions and their theories of change. This study explored the rate of instructional interactions within treatment groups to determine whether they offered explanatory power of an empirically validated Tier 2 kindergarten mathematics…

To better address the many consequences of peer victimization, research must identify not only aspects of individuals that put them at risk for victimization, such as aggression, but also aspects of the context that influence the extent of that risk. To this end, this study examined the contextual influences of gender, same-sex peer group norms of…

Based on a one-year longitudinal experimental study with 3,782 kindergarten school children across 15 countries, this article examines the association between prayer and happiness. Results show that the post-test scores on the faces scale were higher for the participant group who had taken the prayer lessons vis-à-vis the comparison group.…

This study examined longitudinal relations between sleep and body mass index (BMI) from late childhood ([X-bar] age = 9.44 at T1) to early adolescence ([X-bar] age = 11.36 at T3) with a relatively large (n = 273 at T1) and diverse (35% African Americans) sample. Sleep was assessed with actigraphy-based sleep minutes and self-reported sleep…

Purpose: The purpose of the study is to examine the impact of human resource development (HRD) interventions on organizational effectiveness by means of employee competencies which are built by some of the selected HRD interventions. Design/methodology/approach: An integrated research model has been developed by combining the principal factors…

A critical aspect of intervention research is investigating the active ingredients that underlie intensive interventions and their theories of change. This study explored the rate of instructional interactions within treatment groups to determine whether they offered explanatory power of an empirically validated Tier 2 kindergarten mathematics…

This quantitative research examined the contribution of an Online Collaborative Learning (OCL) program on attitudes towards technology in terms of technological anxiety, self-confidence and technology orientation among M.Ed. students. The advanced online collaborative program was implemented at two teacher training colleges in Israel for a period…

Multilevel modeling (MLM) is frequently used to detect group differences, such as an intervention effect in a pre-test--post-test cluster-randomized design. Group differences on the post-test scores are detected by controlling for pre-test scores as a proxy variable for unobserved factors that predict future attributes. The pre-test and post-test…
