The effects of assessing character strengths vs. psychopathology on mood, hope, perceived stigma and cognitive performance in individuals with psychosis.

OBJECTIVES: The main objective of the present study was to investigate whether assessments of psychopathology vs. character strengths were associated with systematic differences concerning transient psychological states (i.e., cognitive performance, state mood, optimism, therapy motivation, perceived stigma) in individuals with psychotic disorders. An additional goal was to evaluate the acceptance and appraisal of a subsequent online character-strength intervention, consisting of top-two strengths feedback, and to explore associations between character strengths and psychotic symptoms. The study thus aimed to contribute to the discussion on the extension of current treatment approaches for schizophrenia through positive psychological interventions. METHODS: The study was implemented online applying a randomized within-subject cross-over design in N = 39 patients with self-reported psychosis. After a baseline assessment, briefly capturing psychological states (including cognition: TMT A/B, positive and negative affect, motivation for change/ therapy, optimism, and self-stigma) participants were randomly assigned to a first questionnaire block, which addressed either individual character strengths (VIA-IS) or psychopathology (CAPE & BSI). This was followed by a second, brief assessment of transient psychological states, whereafter the second questionnaire block was conducted, this time with the respective opposite (strengths or psychopathology) assessment. A final psychological states assessment was conducted. Afterwards, participants received feedback on their top-two strengths and a brief psycho-education, followed by a qualitative assessment. RESULTS: Contrary to expectations, there were no differences between the psychological states after the pathology vs. character strengths assessment blocks. Character strengths mainly correlated negatively with negative symptoms, with medium to large effect sizes. Participants were generally satisfied with the intervention and rated a focus on personal strengths in psychotherapy as highly important. CONCLUSION: Our main hypothesis stating that the assessment of character strengths (vs. psychopathology) is associated with differences in subsequent psychological states could not be confirmed. Qualitative findings indicate that the emphasis on individual character strengths interventions is well accepted and viewed as important. The associations of character strengths with negative symptoms are important from the background of the cognitive model or defeatist beliefs (e.g., amotivation due to perceiving the self as 'incapable'), which could be addressed in experimental or intervention studies targeting character strengths.
