Striving for unwanted goals: stress-dependent discrepancies between explicit and implicit achievement motives reduce subjective well-being and increase psychosomatic symptoms.

Three studies investigated the relevance of affect regulation, stressful life events, and congruence between explicit achievement orientation and implicit achievement motive for subjective well-being and symptom formation. According to personality systems interactions (PSI) theory, stressful life events were expected to reduce motive congruence when the ability to self-regulate affect was impaired (i.e., state orientation). Consistent with expectations, the State Orientation x Stress interaction predicted incongruence in healthy participants (Studies 1 and 3) and in patients (Study 2). Furthermore, incongruence partially mediated the direct State Orientation x Stress effect on subjective well-being (Studies 1 and 3) and the course of psychosomatic complaints over 3 months (Study 2). In Study 3, the experimental induction of threat reduced motive congruence in state-oriented participants compared with an acceptance condition. Findings underscore the importance of assessing motive congruence as a "hidden stressor" and validate a new operant multi-motive test.
