精神病学的最新趋势强调了从分类方法向维度方法转变的必要性。对这种转变至关重要的是工具的可用性，以客观地量化行为的维度。本研究的重点是社会动机，行为的一个维度，是一系列精神疾病的核心，但目前存在的检测特别少。在研究1（N = 48）中，健康成年人完成了金钱奖励任务和社会奖励任务，然后完成了查普曼身体和社会快感缺失量表。在研究2（N = 26）中，招募了一个独立样本，以评估研究1结果的稳健性。使用信号检测理论对奖励任务进行分析，以量化奖励线索对参与者反应的影响。在研究1和研究2中，社交快感缺失得分与社会奖励任务中的反应偏差变化呈负相关，但在金钱奖励任务中则不相关。社会性快感缺失分数的中位数分裂证实，与低社会性快感缺失的参与者相比，高社会性快感缺失的参与者在社会奖励任务中的反应偏差变化较小。本研究证实，社会性快感缺失选择性地影响了多少个人改变他们的行为的基础上存在的社会奖励线索，并建立了一个工具，量化社会奖励反应的维度。
Recent trends in psychiatry have emphasized the need for a shift from categorical to dimensional approaches. Of critical importance to this transformation is the availability of tools to objectively quantify behaviors dimensionally. The present study focuses on social motivation, a dimension of behavior that is central to a range of psychiatric conditions but for which a particularly small number of assays currently exist. In Study 1 (N = 48), healthy adults completed a monetary reward task and a social reward task, followed by completion of the Chapman Physical and Social Anhedonia Scales. In Study 2 (N = 26), an independent sample was recruited to assess the robustness of Study 1’s findings. The reward tasks were analyzed using signal detection theory to quantify how much reward cues bias participants’ responses. In both Study 1 and Study 2, social anhedonia scores were negatively correlated with change in response bias in the social reward task but not in the monetary reward task. A median split on social anhedonia scores confirmed that participants with high social anhedonia showed less change in response bias in the social reward task compared to participants with low social anhedonia. This study confirms that social anhedonia selectively affects how much an individual changes their behavior based on the presence of socially rewarding cues and establishes a tool to quantify social reward responsiveness dimensionally.
