Stress and suicidal ideation: The role of state or trait anhedonia in a moderated mediation model

Background Recent works suggested taking into account the severity and the type of anhedonia when examining suicidal ideation. The present study investigated a moderated mediation model addressing the psychosocial mechanisms that account for the association between state or trait anhedonia and suicidal ideation. Methods State anhedonia was assessed using the Snaith-Hamilton Pleasure Scale, while trait […]

Physical and social anhedonia are associated with suicidality in major depression, but not in schizophrenia

Objective This cross-sectional study investigated the association of physical and social anhedonia with suicidality in patients with major depressive disorder (MDD), schizophrenia, and in non-psychiatric controls. Method All participants completed the revised Physical Anhedonia Scale (RPAS) and the revised Social Anhedonia Scale (RSAS) and were subdivided according to positive life-time suicide attempt history. MDD patients […]

The specific roles of loss of interest and loss of pleasure in recent suicidal ideation

Background Evidence suggests that recent changes in anhedonia may be more predictive of suicidal ideation than either state or trait anhedonia alone. However, the individual role that anhedonia symptoms play in suicidality is not yet well established. Methods This study investigated whether state, trait, and recent changes in anhedonia predicted recent suicidal ideation, using cross-sectional […]

State anhedonia and suicidal ideation in adolescents: The role of loss of interest in friends

Background: Recent work suggests that state anhedonia and its social aspect of loss of interest in people was an important predictor of suicidal ideation in adults. Aim: The current study investigated the relationship between state anhedonia, trait anhedonia, suicidal ideation, and suicide attempts in adolescents. Method: State anhedonia was assessed using the anhedonia subscale from the Child Mood and Feelings […]

Relationships between anhedonia, suicidal ideation and suicide attempts in a large sample of physicians

BACKGROUND: The relationships between anhedonia and suicidal ideation or suicide attempts were explored in a large sample of physicians using the interpersonal psychological theory of suicide. We tested two hypotheses: firstly, that there is a significant relationship between anhedonia and suicidality and, secondly, that anhedonia could mediate the relationships between suicidal ideation or suicide attempts […]

The association between anhedonia, suicide ideation, and suicide attempts: A replication in a Persian student sample

Research suggests that anhedonia, a common symptom of depression, may be uniquely associated with suicidal behavior. However, little research has examined this association across cultures. To address this limitation, this study attempted to replicate a recent anhedonia and suicide study (conducted in a western culture) in a Persian sample using the Specific Loss of Interest […]

Anhedonia predicts suicidal ideation in a large psychiatric inpatient sample

This study examined the relationship among symptoms of anhedoniaand suicidal ideation at baseline, at termination, and over time in 1529 adult psychiatric inpatients. Anhedonia was associated with suicidalitycross-sectionally at baseline and at termination. In addition, change in anhedonia from baseline to termination predicted change in suicidality from baseline to termination, as well as level of suicidality at termination; moreover, […]

A short-term longitudinal examination of the relations between depression, anhedonia, and self-injurious thoughts and behaviors in adults with a history of self-injury

Background Limited research has addressed the role of anhedonia in predicting suicidality and/or nonsuicidal self-injury (NSSI) in adults, despite evidence suggesting that loss of interest or pleasure may increase vulnerability for self-inflicted harm, even beyond other depressive symptoms. Methods In the current study, we explored the role of symptoms of depression and recent changes in anhedonia in predicting suicidality, NSSI ideation, and perceptions […]

Struggling toward reward: Recent experience of anhedonia interacts with motivation to predict reward pursuit in the face of a stressful manipulation.

Anhedonia, or the loss of interest and/or pleasure, is a core symptom of depression. Individuals experiencing anhedonia have difficulty motivating themselves to pursue rewarding stimuli, which can result in dysfunction. Action orientation is a motivational factor that might interact with anhedonia to potentially buffer against this dysfunction, as action-oriented individuals upregulate positive affect to quickly […]
