초록/요약
Background: Attending to the similarities between depressive symptoms and anhedonia in schizophrenia, research on the development of psychosocial interventions targeting negative symptoms in relation to reward-processing system is in resurgence. Yet, there is no study available for studying the effect of self-monitoring, a prominent component of psychotherapy, in negative symptoms of individuals with schizophrenia. Methods: 37 participants completed 5-week sessions of self-monitoring component of Behavioral Activation in randomized controlled trial. 18 participants received a modified component of self-monitoring, activity monitoring (AM). The active control group received neutral supportive intervention with the same therapists (AC). Negative symptoms were assessed using Positive and Negative Syndrome Scale (PANSS) and Brief Negative Symptoms Scale (BNSS), along with neurocognitive function measures and dysfunctional attitude scale. Results: Significant group × time interactions were found in BNSS Anhedonia and Avolition measures, where AM scored significantly lower compared to AC. There was no significant group interaction in dysfunctional attitude and negative symptoms assessed by PANSS. Discussion: A brief 5-week of self-monitoring had effects on lowering anhedonia and avolition symptoms. Self-monitoring activities and mood may be a viable treatment option for negative symptoms in schizophrenia.
