An experimental study on the effectiveness of emotion regulation in patients with acute delusions.

BACKGROUND

Patients with psychotic disorders report to apply more maladaptive and less adaptive emotion-regulation (ER) strategies compared to healthy controls. However, few studies have used experimental designs to investigate the success in ER and the results of those at hand are equivocal.

AIM

This study investigated whether patients with delusions show problems in downregulating negative affect via cognitive ER-strategies.

METHOD

Patients with schizophrenia spectrum disorders and acute delusions (n = 78) and healthy controls (n = 41) took part in an ER-experiment, in which they were instructed to downregulate anxiety and sadness via three ER-strategies (reappraisal, distraction, acceptance) or not to regulate their emotions (control-condition). ER-success was measured as the change in subjective emotion-intensity and physiological indicators (skin conductance and heart rate) from before to after regulation and was analyzed with mixed-repeated-measures ANOVAs.

RESULTS

We found a significant effect of the ER-strategy in the sense that the subjective emotion-intensity was significantly lower after applying the reappraisal- and distraction-strategies than after the just view-condition (p's < .001). This effect was not found for the acceptance strategy (p = .060). There was no ER-strategy ∗ time ∗ group interaction-effect F(4.918, 575.416) = 0.778, p = .564, ƞ = 0.007. In all conditions, skin conductance decreased from pre- to post regulation (p < .001).

CONCLUSION

Our results indicate that patients with acute delusions can successfully apply cognitive ER-strategies. Before pursuing the relevant clinical implications of this finding, further research is needed to explore the role that the type of instruction has on ER-success and the extent to which the findings can be generalized to real life settings.
