This research integrates three concepts (personality, family correlates and emotion regulation) in a predictive model of wellbeing. We measured the impact of the personality structure, the adult attachment style, the style for socializing internalizing and externalizing emotions and the emotion regulation strategies (cognitive reappraisal, expressive suppression) on general wellbeing. A set of eight self-administered scales were filled up by 516 subjects, aged between 14 and 34 (M = 18.62; SD = 3.32). The results show that emotional stability predicts wellbeing on all four dimensions: positive affects, negative affects, emotional distress and life satisfaction. Emotion regulation strategies are predictors for (positive and negative) affects only, and not for emotional distress or life satisfaction.
