Social jetlag and trajectories of mood symptoms and reward responsiveness in individuals at low-risk, high-risk, and with bipolar spectrum disorders: An ecological momentary assessment study

Social jetlag is significantly associated with differences in trajectories of depressive symptoms among participants with varying reward sensitivity, with 130 participants involved.

• Greater social jetlag is linked to a greater increase in depressive symptoms over 20 days for those with high reward sensitivity and bipolar spectrum disorder.
• Participants with moderate reward sensitivity showed less increase in depressive symptoms compared to those with higher sensitivities.
• Social jetlag was associated with depressive symptom lability during the ecological momentary assessment period.
• The association between social jetlag and depressive symptom lability approached significance when accounting for self-reported sleep duration.
