Key result
Dysphoria predicts subsequent depression through lower valence and higher temporal network density.
Why the study?
Little is known about the psycho-physiological mechanisms of affective forecasting deficits in relation to specific daily events in depression.
Do affective forecasting dynamics and HRV differ between dysphoric and non-dysphoric individuals, and do they predict subsequent depression?
Observational (n=100)
Do affective forecasting dynamics and HRV differ between dysphoric and non-dysphoric individuals, and do they predict subsequent depression?
Dysfunctional affective forecasting dynamics and HRV may serve as early warning signs and predictors of depression.
May flag depression risk via affective dynamics; hypothesis-generating, requiring prospective validation before clinical use.
Background: Deficits in affective forecasting are closely associated with the development and maintenance of depression. While previous research has shown that emotional fluctuations and future thinking are prevalent in daily life, little is known about the psycho-physiological mechanisms of affective forecasting deficits in relation to specific daily events in depression. Methods: Dysphoric (N = 40) and non-dysphoric (N = 60) individuals completed assessments of their anticipatory emotions, experienced emotions, and consummatory emotions for specific daily events 3 times a day for consecutive 14 days. Heart rate variability (HRV) data was collected using customized smartwatches. Temporal network analysis was used to estimate time-lagged associations among anticipatory, experienced and consummatory emotions. Results: Dysphoric individuals reported significantly lower levels of anticipatory, experienced, and consummatory valence compared to non-dysphoric individuals. Furthermore, distinct patterns emerged in the temporal networks of anticipatory, experienced, and consummatory emotions between the dysphoric and non-dysphoric groups. Network density was considerably higher in dysphoric individuals than in non-dysphoric individuals. In addition, HRV was predictive of anticipatory valence across all participants. Moreover, the dynamic associations between anticipatory and experienced emotions predicted subsequent depression, even after accounting for baseline depressive symptoms. Conclusion: Our findings reveal provide novel insights into the psycho-physiological mechanisms of affective forecasting deficits in depression, with several clinical implications: (1) dysfunctional affective forecasting dynamics may serve as salient early warning signs and sensitive predictors of depression; and (2) improving the flexibility of affective forecasting may be a promising target for addressing depression.

Yang et al. (2026) conducted an observational in Depression (n=100). Ecological monitoring of affective forecasting vs. Non-dysphoric individuals was evaluated on Anticipatory, experienced, and consummatory valence and temporal network density. Dysphoric individuals exhibited lower anticipatory, experienced, and consummatory valence and higher temporal network density than non-dysphoric individuals, predicting subsequent depression.
