To examine prospectively whether high reward experience (the ability to generate positive affect boosts from pleasurable daily events) protects against affective symptoms and whether environmental or genetic risk factors moderate protective effects.
At baseline, 498 female twins participated in an experience sampling study measuring reward experience in daily life. They also completed questionnaires on childhood adversity and recent stressful life events (SLE). Affective symptoms were measured at baseline and at four follow-ups using SCL-90 anxiety and depression subscales. Co-twin affective symptoms were used as indicators of genetic risk.
Baseline reward experience did not predict follow-up affective symptoms, regardless of level of genetic risk. However, high reward experience was associated with reduced future affective symptoms after previous exposure to childhood adversity or recent SLE.
High daily life reward experience increases resilience after environmental adversity; modification of reward experience may constitute a novel area of therapeutic intervention.
前瞻性地检验高奖励体验（即从愉快的日常事件中产生积极情绪的能力）是否能预防情感症状，以及环境或遗传风险因素是否能调节保护作用。
在基线时，498 名女性双胞胎参与了一项体验抽样研究，测量日常生活中的奖励体验。她们还完成了关于童年逆境和近期生活压力事件（SLE）的问卷。使用 SCL-90 焦虑和抑郁分量表在基线和四次随访时测量情感症状。同卵双胞胎的情感症状被用作遗传风险的指标。
无论遗传风险水平如何，基线时的奖励体验都不能预测后续的情感症状。然而，在经历过童年逆境或近期 SLE 后，高奖励体验与未来情感症状的减少有关。
日常生活中的高奖励体验增加了对环境逆境的适应能力；奖励体验的改变可能构成治疗干预的一个新领域。
