In this study, we examined family resilience as a mediator in the relationship between family functioning and four types of well-being (overall life satisfaction, satisfaction with family life, flourishing, and positive mental health). This study was conducted among university students attending the University of Chlef (N = 350; 304 females, 46 males; mean age 22.34). The participants completed the Family Functioning Scale (FFS), Walsh Family Resilience Questionnaire (WFRQ), Satisfaction with Family Life Scale (SWFLS), Satisfaction With Life Scale (SWLS), Flourishing Scale (FS), and Positive Mental Health Scale (PMHS). With bootstrapping, the Hayes’ PROCESS macro for SPSS was used to analyze the mediated effects of family resilience. Family resilience partially mediates family functioning and overall life satisfaction, satisfaction with family life, and flourishing. Family resilience fully mediates the relationship between family functioning and positive mental health.
