Investigation of momentary negative symptoms in patients with early psychosis in daily life: An experience sampling study

A systematic review of the application of experience sampling methodology to measure anhedonia in psychiatry and mental health

“…How pleasant was this event?" (Fung et al, 2023). Fewer studies specifically asked about social events (i.e., social anhedonia; n = 22, 25.58%) (e.g., modelled as the relationship between "I feel pleasant being in their company" and the average of positive affect items including "I feel cheerful", "I feel satisfied", "I feel enthusiastic", "I feel relaxed) (Fung et al, 2023).…”

Almost half of the included studies (n = 41, 47.67%) explored anhedonia in general without specifying a particular context (e.g., "How much pleasure are you having?")…”

“…Converging evidence in young adults and adults indicates that there is a positive within-person association between positive affect and event pleasantness, positive events, social contact, and psychological or behavioral rewards (or negative association between anhedonia and social contact); these associations generally do not differ by baseline depressive, anhedonia, or schizotypy symptoms (Heininga et al, 2019a;Heininga et al, 2019b;Heininga et al, 2017a;Kwapil et al, 2012;Schricker et al, 2023;van Roekel et al, 2016; for an exception, see Kwapil et al, 2009). In young adults and adults with early psychosis, there was similarly limited evidence for blunting of affective experiences (Hermans et al, 2021), with some studies showing larger increases in positive affect when in the company of others (Collip et al, 2014) and when engaging in pleasant activities (Fung et al, 2023) compared to controls. In adults with psychotic disorders, however, patients reported more event anhedonia compared to relatives and controls, but there were no differences in social anhedonia (Daemen et al, 2022).…”

“…This association is evident at the within-person level in healthy samples (Heininga et al, 2017a; ANHEDONIA ESM REVIEW 37 Kwapil et al, 2012) and in sub-clinical samples (cross-level interactions). For example, those with early psychosis display heightened reactivity to pleasant events and social company compared to controls (Collip et al, 2014;Fung et al, 2023), although the nature and intensity of this relationship may vary based on symptom severity (Daemen et al, 2022;Oorschot et al, 2012;Oorschot et al, 2013). Research investigating other contextual factors is fragmented, but there is emerging support for contemporaneous and temporal links between stress and anhedonia (possibly bidirectional) and between sleep and anhedonia (Bean & Ciesla, 2021;Gerritsen et al, 2019;Heininga et al, 2019a;Kalmbach et al, 2017;Peterson et al, 2021;Wieman et al, 2022a).…”
