本研究探讨精神分裂症患者快感缺乏与积极情感（PA）和消极情感（NA）特质维度的关系。精神分裂症的社会功能差和这些情感的个体差异之间的关系也进行了研究。精神分裂症门诊患者（n = 37）和正常对照组（n = 15）在基线评估和大约90天后再次进行评估。与精神分裂症患者享乐能力降低的假设相一致，患者报告的身体和社会快感缺失显著高于对照组，PA显著低于对照组。然而，精神分裂症组也报告了显着更大的NA和社交焦虑比对照组，在支持这些情感的个体差异的倾向性观点，特质措施表现出重测信度，和精神分裂症组和对照组之间的组间差异是稳定的90天的随访期。在精神分裂症组中，躯体和社交快感缺失与特质PA呈显著负相关;然而，社交而非躯体快感缺失与NA和社交焦虑呈显著正相关。精神分裂症组的社交功能较差与更严重的身体和社交快感缺失以及更严重的NA和社交焦虑有关。或者，更大的特质PA与更好的社会功能有关。这些结果表明，精神分裂症的特点是低PA和NA升高，这些情感特征是一个稳定的疾病特征，结果还表明，精神分裂症的情感和社会功能之间的重要联系。
This study examines the relationship between anhedonia and the trait dimensions of positive affect (PA) and negative affect (NA) in schizophrenia. The relationship between poor social functioning in schizophrenia and these individual differences in affectivity is also examined. Schizophrenia outpatients (n = 37) and normal controls (It = 15) were assessed at a baseline evaluation and again approximately 90 days later. Consistent with the hypothesized decrease in hedonic capacity in schizophrenia, patients reported significantly greater physical and social anhedonia and less PA than controls. However, the schizophrenia group also reported significantly greater NA and social anxiety than did controls, In support of the dispositional view of these individual differences in affectivity, trait measures demonstrated test-retest reliability, and group differences between the schizophrenia group and controls were stable over the 90-day followup period. Within the schizophrenia group, physical and social anhedonia were comparably negatively correlated with trait PA; however, social but not physical anhedonia was significantly positively correlated with NA and social anxiety. Poor social functioning in the schizophrenia group was associated with greater physical and social anhedonia and greater NA and social anxiety. Alternatively, greater trait PA was related to better social functioning. These findings indicate that schizophrenia is characterized by both low PA and elevated NA and that these affective characteristics are a stable feature of the illness, The results also suggest important links between affect and social functioning in schizophrenia.
