The present meta‐analysis summarizes the international basis of evidence regarding links between psychologically meaningful risk factors and political violence outcomes among adolescents and young adults. We synthesized 422 cross‐sectional effect sizes from 95 samples (67 index publications, 23 countries), using robust variance estimation. The results of seven longitudinal studies and one intervention study are discussed in a narrative manner. We detected significant effects for depression ( r = .07, k = 10); empathy ( r = −.16, k = 7); aggression ( r = .24, k = 10); identification ( r = .21, k = 30); relative group deprivation ( r = .19, k = 11); realistic threat ( r = .30, k = 27); symbolic threat ( r = .28, k = 10); negative intergroup emotions ( r = .25, k = 9); experiences of discrimination ( r = .11, k = 12); dissatisfaction with the police, political actors, and institutions ( r = .11, k = 32); and negative attitudes toward democracy ( r = .17, k = 10). No significant effect was found for self‐esteem, intolerance of uncertainty, narcissism, or exposure to intergroup conflict. The reviewed longitudinal and intervention studies mainly confirm these cross‐sectional results. The script and our data are available in an open online repository.
