BACKGROUND: Recent works suggest recent changes in anhedonia may be specifically predictive of key elements of psychopathology. The present study aimed to identify the trajectories of state anhedonia and recent changes in anhedonia, and to investigate their associations with other psychiatric syndromes over time.
METHODS: A total of 859 college students were assessed at three time points. State anhedonia was assessed using the Snaith Hamilton Pleasure Scale and recent changes in anhedonia were assessed with a subscale extracted from the Symptom Check-List-90. The Latent Growth Curve Modelling analysis was used to analyze trajectories. Associations with anhedonia were investigated with logistic regression models.
RESULTS: Three state anhedonia trajectories and two recent changes in anhedonia trajectories were identified. The decreasing trajectory was the most prevalent class in both two types of anhedonia. Depression and suicidal ideation predicted recent changes in anhedonia whereas other psychiatric syndromes predicted state anhedonia.
CONCLUSIONS: The current study highlighted the development trajectories of different measures of anhedonia. The results showed that the relationships between anhedonia and psychiatric syndromes were different according to the kind of anhedonia.
