Consisting of two cross-sectional studies, the present study investigated whether psychological flexibility mediates the relations between self-concealment and negative psychological outcomes. Study 1 examined whether psychological flexibility mediates the relations between self-concealment and emotional distress in stressful interpersonal situations. In addition to replicating results of Study 1, Study 2 investigated whether psychological flexibility mediates the relationship between self-concealment and general psychological ill-health. Psychological flexibility was found to mediate the relation between self-concealment and emotional distress in stressful interpersonal settings and to partially mediate the relationship between self-concealment and general psychological ill-health
