Reward functioning in PTSD: A systematic review exploring the mechanisms underlying anhedonia
Abstract
Post-traumatic stress disorder (PTSD) is a debilitating psychiatric disorder. An important diagnostic feature of PTSD is anhedonia, which may result from deficits in reward functioning. This has however never been studied systematically in PTSD. To determine if PTSD is associated with reward impairments, we conducted a systematic review of studies in which reward functioning was compared between PTSD patients and healthy control participants, or investigated in relation to PTSD symptom severity. A total of 29 studies were included, covering reward anticipation and approach ('wanting'), and hedonic responses to reward ('liking'). Overall, results were mixed, although decreased reward anticipation and approach and reduced hedonic responses were repeatedly observed in PTSD patients compared to healthy controls. Decreased reward functioning was seen more often in female than in male PTSD samples and most often in response to social positive stimuli. Though more research is needed, these findings are a first step in understanding the possible mechanisms underlying anhedonia in PTSD.

“Deficits in reward functioning may be a mechanism underlying anhedonia (lack of pleasure) associated with PTSD (68).”
From A Biopsychosocial Overview of the Opioid Crisis: Considering Nutrition and Gastrointestinal Health (2019) · cites this paper as [68]
In the citing paper
“While early research focused on fear-related processes, a growing recognition of alterations in reward processing (115, 116) led to a reconceptualization of PTSD as an imbalance between approach (reward-related) and avoidance (fear-related) systems (117–119).”
From A transdiagnostic perspective on social anhedonia (2019) · cites this paper as [118]
In the citing paper
“Overall, however, a tendency to both reduced consummatory and motivational reward was noted, especially in females with PTSD and in response to positive social stimuli compared to nonsocial stimuli, suggestive of social anhedonia (118).”
From A transdiagnostic perspective on social anhedonia (2019) · cites this paper as [118]
In the citing paper
“Reduced motivation to approach socially rewarding stimuli may be particularly evident in those with PTSD when greater effort is needed to gain reward (118), suggesting reduced sensitivity in the cognitive underpinning for “wanting” social connections.”
From A transdiagnostic perspective on social anhedonia (2019) · cites this paper as [118]
In the citing paper
“Specifically, decreased sensitivity to social rewards is documented in schizophrenia (61), eating disorders (93), PTSD (118), and autism spectrum disorders (146).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
