Anhedonia is believed to be transdiagnostic symptom exist in various disorders including schizophrenia, major depressive disorder, and autism spectrum disorder. However, very few studies attempted to profile subclinical samples with schizophrenia, depressive, and autistic symptoms using measures of anhedonia scales. This study adopted a cluster analytical approach to examine the anhedonia profile in 46 individuals with schizotypal trait (ST), 43 subthreshold depression (SD), 27 autistic trait (AT), and 41 healthy controls. They completed a set of checklists capturing different dimensions of anhedonia including the anticipatory and consummatory interpersonal pleasure scale, the temporal experience of pleasure scale, the motivation and pleasure scale and the belief about pleasure scale. Cluster analysis was conducted on these measures among the merged sample of ST, SD, and AT. To validate the clusters, we administered measures on nonsocial reward processing, self-reported empathy, and social functioning. A three-cluster solution was found to be the best fit. Cluster 1 (n = 48) showed high pleasure experience, motivation, and belief about pleasure and spread evenly across three groups. Cluster 2 (n = 31) was characterized by low levels of anticipatory and consummatory pleasure specifically for the social domain, largely comprised of individuals with ST. Cluster 3 (n = 37) showed low levels of consummatory pleasure, motivation, and belief about pleasure, largely comprised of individuals with SD. The resultant clusters differed in social process and functioning. The current findings suggested distinct anhedonia subtypes within different subclinical populations. These findings may have implications for early detection and prevention for anhedonia.© 2025 The Author(s).
