Purpose: The systematic review aimed to review and evaluate constructs and measures of emotion regulation (ER) in the psychosis spectrum population literature. The empirical study aimed to examine the feasibility and acceptability of a trans-diagnostic emotion regulation (ER) group developed for an acute inpatient setting. Methods: The literature was systematically searched for research related to the measurement of emotion regulation (ER) in a psychosis spectrum population. A mixed method design was employed to assess acceptability and feasibility of a six session ER skills group delivered in an acute mental health inpatient setting. The group intervention was developed and piloted over a 5 month period. The mixed method design included a multiple single case series design and qualitative exit interviews, conducted with eight participants. Results: 24 papers met criteria for inclusion in the systematic review. 15 different self-report tools were identified as measures of ER strategies in this review. Descriptive data from the empirical study indicated high attendance and low attrition rates. Group level analysis identified large effect sizes for change in ER skills. Case series data indicated that sustained change, on at least one measured variable, occurred for four participants. Qualitative themes triangulate findings related to acceptability of the group, change in ER strategies and increased emotional acceptance. Conclusions: ER conceptualisation is variable in the literature reviewed, where the understanding of how ER and psychosis are linked is limited. The emphasis on the literature reviewed is on cognitive strategies of ER. The pilot study indicates that the intervention is feasible and acceptable, with preliminary evidence identifying potential clinical benefits. The challenges in evaluating interventions in an acute inpatient environment are discussed.
