Unhappy or unsatisfied: distinguishing the role of negative affect and need frustration in depressive symptoms over the academic year and during the COVID-19 pandemic.

Mental health problems are becoming increasingly prevalent across college campuses. Past research has found that negative affect and frustration of basic psychological needs contribute to the development of depressive symptoms, but there is limited research which compares whether these are antecedents or concomitants of depressive symptoms. The present set of studies aimed to distinguish the differential associations of affect and need frustration on depressive symptoms. Students (N = 379; N = 235) completed measures on negative affect, need frustration (e.g., relatedness, competence, and autonomy), and depressive symptoms over an academic year and during the start of the COVID-19 pandemic. In both samples, fully cross-lagged path models were used to examine the relation between need frustration, negative affect, and depressive symptoms over time. Across both studies, basic psychological need frustration was the only consistent predictor of both negative affect and depressive symptoms over time, suggesting that need frustration is an antecedent of depressive symptoms over time, and especially during vulnerable time periods. Additionally, in Study 2, reports from close others confirm that need frustration is the largest indicator of depressive presentation in students. These results highlight the relative importance of basic psychological need frustration in predicting depressive symptoms in university students.
