科学领域:

精神病学是一个精神病学.
临床心理学临床心理学
神经科学是一个神经科学.

背景情况:

奖励敏感性与精神障碍,特别是抑郁症有关.
缺乏纵向数据来澄清奖励敏感性和精神病理学之间的时间关系.
奖励处理可能是一个跨诊断机制,但这可能受到伴随性抑郁症的影响.

研究的目的:

研究奖励敏感性和精神病理症状的时间动态.
检查抑郁症在奖励敏感性与其他疾病之间的关系中的潜在调解作用.
为了澄清降低奖励灵敏度是否在精神健康症状出现之前或之后.

主要方法:

这是一项三波纵向在线调查,共有453名参与者.
评估奖励敏感性 (PVSS-21),抑郁症 (PHQ-9),饮食障碍症状 (EDE-Q-8),社会焦虑 (Mini-SPIN) 和酒精消费 (AUDIT-C).
通过路径分析利用交叉滞后的面板和调解分析.
