A New Intervention to Reduce Anhedonia in Schizophrenia

Meta-analyses of cognitive behavioral therapy for positive symptoms of schizophrenia have demonstrated its effectiveness in reducing hallucinations or delusions. In schizophrenia “negative symptoms’ refer to a reduction of normal functioning, and it encompasses apathy, anhedonia, flat effect, avolition, social withdrawal, and, sometimes, psychomotor retardation. The purpose of this study is the idea that Anhedonia is a challenging symptom of schizophrenia and remains largely recalcitrant to current pharmacological treatments. The goal of this exploratory pilot study was to assess if a cognitive-sensory intervention could improve anticipatory pleasure. Results show that the patients improved on the anticipatory scale of the Temporal Experience of Pleasure Scale. Daily activities of the patients were also increased. In nursing research, it has been shown that the sense of mastery is negatively correlated with negative symptoms or even with the fact of being left alone. Two research questions were addressed in a sample of five participants. Does cognitive-sensory training in anticipatory pleasure in persons with schizophrenia? Does cognitive-sensory training in anticipatory pleasure lead to an increase in the number and complexity of daily activities performed by persons with schizophrenia? They did not expect that anticipatory pleasure cognitive skills training would directly improve consummatory pleasure. If persons with schizophrenia show a deficit in their ability to anticipate pleasure rather than consummatory pleasure, then it becomes possible to consider cognitive training might help these individuals anticipate pleasure from foreseeable, future activities. I feel the author did a good job using literature to support their predictions and I was convinced by their argument. The author used well supporting concepts to prove their points as they discussed theories about Anticipatory Pleasure Skills Training: A New Intervention to Reduce Anhedonia
