The latent growth model (LGM) is a popular tool in the social and behavioral sciences to study development processes of continuous and discrete outcome variables. A special case are frequency measurements of behaviors or events, such as doctor visits per month or crimes committed per year. Probability distributions for such outcomes include the…

This study examined the relationships among home-based parental involvement, study habits, and academic achievement using structural equation modeling. The sample consisted of 566 eighth-grade students in Taiwan, and their mean age was 14.35. The data for home-based parental involvement and study habits was collected in the "first survey…

Background: Modelling academic self-concept through second-order factors or bifactor structures is an important issue with substantive and practical implications; besides, the bifactor model has not been analysed with a Chinese sample and cross-cultural studies in the academic self-concept are scarce. Likewise, latent structure validity evidence…

Background: Based on learned helplessness theory and conservation of resources theory, the present study explores the role of schools' social environments (i.e., school belonging, school exclusion, and teacher-student relationships) as potential buffers and amplifiers in students' development of learned helplessness during adolescence. Aims: We…

The current study investigated the indirect effects of anger on the four forms and functions of relational aggression (i.e., proactive indirect, proactive direct, reactive indirect, reactive direct) through anger rumination in a sample of 1020 Greek adolescents (504 boys). Males used more proactive direct and indirect relational aggression,…

Studying development processes, as they unfold over time, involves collecting repeated measures from individuals and modeling the changes over time. One methodological challenge in this type of longitudinal data is separating retest effects, due to the repeated assessments, from developmental processes such as maturation or age. In this article,…

Longitudinal research is often interested in identifying correlates of heterogeneity in change. This paper compares three approaches for doing so: the mixed-effects model (latent growth curve model), the growth mixture model, and structural equation model trees. Each method is described, with special focus given to how each structures…

Adolescents around the world are increasingly exposed to cyberhate. More knowledge is needed to understand how adolescents cope with cyberhate and how they can be supported when exposed. To this end, the present study investigated the associations between parental mediation of Internet use and adolescents' problem-focused coping strategies for…

Background: Adolescent mental illness is of increasing concern, with prevalence increasing especially in females in the United Kingdom. While service-related barriers can deter help-seeking, the role of family support and engagement in family activities, and attitudes towards seeking help from a doctor has received little attention. Studies…

Structural equation modelling (SEM) with longitudinal survey data was used to test a proposed developmental model of the association of family income (with children aged 6-9) to parent behaviours (for children at 10 years of age) and adolescent cognitive achievement and behaviour problems (at age 15). Data from the Child Development Supplement and…

Self-determination, as a person dispositional characteristic, is indeed influenced by situational characteristics that shape actions across contexts. Research has also reported differences in self-determination as a function of personal factors, but there is a need to integrate this knowledge in a general model aiming to analyse the impact of…

This study investigates the association between mentoring and future expectations of youth in residential placements in Israel, and how family engagement during care and sense of belonging mediate this relationship. The participants included 213 adolescents (16-19 years old). Structural equation modeling revealed that mentoring contributed to the…

The present article focuses on classroom climate effects in the context of multi-level structural equation modelling. We first discuss the need to appropriately model classroom climate as a classroom-level construct. We then analyse the effects of classroom climate (academic goal structures and social goal structures) on students' motivation in…

Instruments to measure self-determination have only been available in the Spanish language to date, for adolescents with intellectual disability (ID). However, given the development of a new measure of self-determination for youth with and without disabilities, the "Self-Determination Inventory," there is a need to adapt and validate…

Purpose: The purpose of this research was to investigate the pattern of relationship between attachment styles, gaming addiction and empathy among adolescents. Research Methods: The correlational survey method was used herein. In order to explain the pattern of relationship between the variables, a theoretical model based on the literature was…
