Trends in the Link Between Perceived Social Support and Life Satisfaction in Adolescents (2013/14-2021/22): A Cross-National Study.

Objectives: This repeated cross-sectional study aimed to (a) report trends in adolescents' perceived family, friend, classmate, and teacher support, (b) estimate the extent to which each source of support related to life satisfaction across space and time, and (c) ascertain whether sociodemographic factors moderated the relationship in question. Methods: We relied on data pertaining to the 2013/14, 2017/18, and 2021/22 waves of the Health Behaviour in School-aged Children study. The examined sample covered 44 countries and regions (n = 716,083; M AGE = 13.6; SD AGE = 1.64; 50.7% female). Results: The level of all sources of perceived social support slightly decreased over the examined period (all ω2 < .01). Family support involved the largest association with life satisfaction (ß = 0.16); friend support, the lowest one (ß = 0.03). These associations varied only tenuously across space and time. Sociodemographic factors moderated the link between perceived social support and life satisfaction to a negligible-to-weak extent. Conclusion: Levels of perceived social support and their associations with life satisfaction subtly changed. Future research may attempt to pinpoint the macrosocial levers of these temporal dynamics.

Validity of the Czech Version of the Therapeutic Factors Inventory - Short Form (TFI-S).

This study's aim was to assess validity of the Czech translation of the Therapeutic Factors Inventory (TFI-S), which includes four factors: Instillation of Hope, Secure Emotional Expression, Awareness of Emotional Impact, and Social Learning. We assessed data from 220 patients who attended a daily three-month treatment program that used integrative group psychotherapy. TFI-S's reliability was satisfactory: at week 12, Cronbach's α was .93 and McDonald's ω was .95. Confirmatory factor analysis showed acceptable fit to our data: at week 12, χ2(146) = 262.5, p < 0.001, CFI = .994, TLI = .992, RMSEA = .071 (90% CI = .057-.084), and SRMR = .063. Predictive validity showed significant correlations between TFI-S factors and pre/post-treatment change. In the conclusion, we discuss possible future potential of cross-cultural research.
