Effectiveness of Self-Affirmation Interventions in Educational Settings: A Meta-Analysis

School and university can be stressful contexts that can become an important source of identity threats when social prejudices or stereotypes come into play. Self-affirmation interventions are key strategies for mitigating the negative consequences of identity threat. This meta-analysis aims to provide an overview of the effectiveness of self-affirmation interventions in educational settings. A peer-reviewed article search was conducted in January 2023. A total of 144 experimental studies that tested the effect of self-affirmation interventions in educational contexts among high school and university students from different social and cultural backgrounds were considered. The average effect of self-affirmation interventions was of low magnitude (dIG+ = 0.41, z = 16.01, p < 0.00), with a 95% confidence interval whose values tended to lie between 0.36 and 0.45 (SE = 0.0253). In addition, moderators such as identity threat, participants' age, and intervention procedure were found. Through a meta-analysis of the impact of self-affirmation interventions in educational contexts, this study suggests that interventions are effective, resulting in a small mean effect size. Thus, self-affirmation interventions can be considered useful, brief, and inexpensive strategies to improve general well-being and performance in educational settings.

Acculturation and school adjustment of children and youth from culturally diverse backgrounds: Predictors and interventions for school psychology

In recent decades, classrooms in many countries have become more culturally diverse. However, students from ethnic minorities and students with immigrant backgrounds are at greater risk of lower social, psychological, and academic adjustment than their native peers. Therefore, schools all over the world are challenged by the question of how to help diverse students adjust to school independent of their ethnic background and family resources. The current special issue focuses on how schools and school psychologists can support positive interethnic attitudes and positive relationships in ethnically diverse classrooms as well as individual well-being, belonging, and academic achievement as different facets of school adjustment. The special issue includes three studies with empirical findings on the role of contextual and individual factors for school adjustment among minority and majority youth in diverse school contexts: Geerlings, Thjis, and Verkuyten study the modeling of outgroup attitudes via teachers' attitudes and more or less consistent behavior, Guerra, Rodrigues, Aguiar, Carmona, Alexandre, and Costa Lopes focus on the interplay of acculturation strategies and of perceived discrimination with school achievement and well-being. Caravita, Strohmeier, Salmivalli, and Di Blasio compare bullying and moral disengagement processes in majority and minority children. Five other studies report evaluations of evidence-based interventions that were tested among ethnically diverse youth in different school settings in two European countries, in Israel, and in the US - two on prejudice reduction (Brenick, Lawrence, Carvalheiro & Berger; Mäkinen, Liebkind, Jasinskaja-Lahti, & Renvik), and three on the effects of 'wise interventions' - self-affirmation and belonging interventions - on trust in teachers and behavioral conduct (Binning et al.), on students' sense of belonging and academic outcomes (Marksteiner, Janke, & Dickhäuser), and on math performance of students (Lokhande & Müller). The evaluation studies show differential effects across contexts and samples that point toward important mechanisms and moderators that may help practitioners adjust these programs to specific contexts.
