Personality affects the vulnerability to the emotional symptoms of depression and anxiety. This study investigated whether stress mindset (general belief about the nature of stress) and coping flexibility (the ability to terminate ineffective coping strategies and adopt alternative ones) mediate the relations of the Big Five personality traits to psychological distress. A total of 260 undergraduate students (60.4% female) in Singapore completed self-reported questionnaires. A series of path analyses was performed. Firstly, a dual-pathway model of stress coping was established, which consisted of (a) a stress-threat-distress pathway where a stress-is-a-threat mindset mediated the association between stressful experiences and psychological distress and (b) a challenge-flexibility-enhancement pathway where coping flexibility mediated the relation of a stress-is-a-challenge mindset to a lower level of psychological distress, without being influenced by stressful experiences. Furthermore, Neuroticism was associated with the stress-threat-distress pathway, with stressful experiences and a stress-is-a-treat mindset mediating the relation of Neuroticism to psychological distress. Conscientiousness was associated with the challenge-flexibility-enhancement pathway, with a stress-is-a-challenge mindset and coping flexibility mediating the relation of Conscientiousness to less psychological distress. Extraversion, Agreeableness, and Openness were directly associated with greater coping flexibility. The findings enrich the literature on personality and stress coping and inform future interventions to promote mental health.
