Beliefs about emotions predict psychological stress related to somatic symptoms

BACKGROUND: Previous research has shown that the more people believe their emotions are controllable and useful (BECU), the less they generally report psychological distress. Psychological distress, in turn, impacts health outcomes, and is among the most frequently reported complaints in psychotherapeutic and psychosomatic practice.

OBJECTIVE: We aimed to examine how BECU predicts psychological distress related to somatic symptoms in a prospective sample from the general population and to replicate this association in two cross-sectional samples of psychosomatic patients.

METHODS: We applied a panel design with an interval of 2 weeks between T1 and T2 in general-population panel-participants (N = 310), assessing BECU and psychological distress related to somatic symptoms via validated self-report measures. Moreover, we cross-sectionally replicated the relationship between BECU and psychological distress in a clinical sample of psychosomatic outpatients diagnosed with somatoform disorders (n = 101) or without somatoform disorders (n = 628).

RESULTS: BECU predicted over and above the lagged criterion panel-participants' psychological distress related to somatic symptoms, β = -.18, p < .001. BECU was also cross-sectionally related to psychological distress in our clinical replication-sample of psychosomatic outpatients diagnosed with somatoform disorders, rS (87) = -.33, p = .002 and in those without, rS (557) = -.21, p < .001.

CONCLUSIONS: BECU as a malleable way of thinking about emotions predicted psychological distress related to somatic symptoms in general-population panel-participants and correlated with the same in two clinical replication samples. BECU thus becomes a promising treatment target in psychotherapeutic approaches.
