“…Among individuals with frank psychosis, those who have experienced childhood trauma or early adversity were more likely to report symptoms of anhedonia. 11 A similar relationship between childhood trauma and anhedonia has been found in those experiencing other forms of psychopathology, such as depressive disorders, 12,13 as well as in non-psychiatric controls. 12 However, to our knowledge, the relationship between childhood trauma and anhedonia is yet to be examined in individuals at CHR, as prior research on this population has typically focused on the relationship between childhood trauma and positive symptoms.…”

Childhood trauma, perceived stress and anhedonia in individuals at clinical high risk for psychosis: multigroup mediation analysis

Background Evidence suggests that both childhood trauma and perceived stress are risk factors for the development of psychosis, as well as negative symptoms such as anhedonia. Previous findings link increases in perceived stress to anhedonia in individuals at clinical high risk for psychosis (CHR) and depression; however, the role of childhood trauma in this relationship has not yet been explored, despite consistent evidence that it is associated with sensitisation to later stress. Aims To examine whether perceived stress mediates the relationship between childhood trauma and anhedonia in a group of youth at CHR as well as in controls (groups with depression and with no diagnosed mental health concerns). Method The study used multigroup mediation to examine the indirect effects of childhood trauma on anhedonia via perceived stress in CHR (n = 117) and depression groups (n = 284) and non-psychiatric controls (n = 124). Results Perceived stress mediated the relationship between childhood trauma and consummatory anhedonia regardless of group status. Perceived stress mediated the relationship between childhood trauma and anticipatory anhedonia for the CHR and depression groups, but not for non-psychiatric controls. Further, groups differed in the magnitude of this relationship, with the effects trending towards stronger for those in the CHR group. Conclusions Our findings suggest a potential transdiagnostic pathway through which childhood trauma contributes to anhedonia across severe mental illness.

“… 23 The cut-off values for the presence of CT include emotional abuse ≤8, physical abuse ≤7, sexual abuse ≤5, emotional neglect ≤9 and physical neglect ≤7. 24 The content of the Chinese version of CTQ was consistent with the original version and had a Cronbach’s α coefficient of 0.77. 25 The Cronbach’s α of five subscales ranged from 0.41 (physical neglect) to 0.68 (physical abuse), 25 which is consistent with the original CTQ, reporting a lower Cronbach’s α coefficient (0.45) for physical neglect.…”

“…Consistent with previous studies, our study found that adolescent girls experience lower levels of pleasure than boys, and emotional neglect has a greater negative impact on girls’ experience of pleasure than boys’ experience of pleasure. 24 41 These findings may be due to the differences in physical development, such as nervous system development and hormonal regulation, between boys and girls. These differences lead to the different pleasure experiences of adolescents of different sexes.…”

ObjectivesTo estimate the level of anhedonia among adolescents and explore the association between anhedonia and childhood trauma (CT).DesignA stratified random cluster sample of adolescents participated in a survey, which included three questionnaires: Snaith-Pamilton Pleasure Scale, Childhood Trauma Questionnaire and Patient Health Questionnaire-9.SettingThe study was conducted in 60 classes in 10 primary, middle and high schools in five economically developed cities along the Southeast Coast of China from April to October 2022.ParticipantsOne thousand seven hundred and forty-five adolescents with ages ranging from 9 to 18 years participated in the study.Primary and secondary outcomesThe primary outcome was the level of anhedonia, CT and depression among adolescents. The association between anhedonia and CT was determined.ResultsThe mean scores of anhedonia, CT and depression were 24.88 (6.18), 36.75 (8.87) and 4.46 (5.36), respectively. Anhedonia scores of boys (24.24±6.12) and girls (25.62±6.16) were different (t=−4.69, p<0.01). After controlling for sex, age, the presence of siblings and depression, CT was associated with adolescent anhedonia. Emotional abuse (β=0.14), emotional neglect (β=0.15) and physical neglect (β=0.10) positively predicted adolescent anhedonia (p<0.01), whereas physical abuse negatively predicted adolescent anhedonia (β=−0.07, p<0.01). Sex had a moderating effect on the relationship between adolescent anhedonia and emotional neglect during childhood, and the negative effect of emotional neglect on adolescent anhedonia in girls was greater than in boys.ConclusionsCT, including emotional abuse, physical abuse, emotional neglect, and physical neglect, was an independent predictor of adolescents’ ability to experience pleasure in daily life. Therefore, awareness of CT should be promoted. Emotional neglect had a more severe effect on anhedonia among girls than among boys, suggesting that emotional neglect should be paid much attention among girls

“…One limitation of this study was the nonnormal distribution of childhood maltreatment, such that childhood maltreatment was positively skewed, with more participants reporting a history of low maltreatment rather than high maltreatment. While we acknowledge that nonnormal distribution (i.e., positively skewed) of childhood maltreatment is normative in the general population (Etain et al, 2010; Sonmez et al, 2021; Uçok & Bikmaz, 2007), we acknowledge that a priori selection of our sample to have a normal distribution across childhood maltreatment could have avoided some of these interpretation problems. To account for this limitation, we graphed our findings and analyzed simple slopes using the 1st quartile, median, and 3rd quartile values of childhood maltreatment rather than the mean and one standard deviation above and below the mean.…”

Following a stressful life event, there is considerable variation in how individuals respond and adapt. Multiple models of risk and resilience show that adverse childhood experiences may be associated with an individual's response to stress later in life. While there is considerable support that early adversity can sensitize the stress response system and lead to adverse outcomes later in life, there is mounting evidence that in adolescence and young adulthood, certain biological predispositions to stress may be associated with resilience in the context of subsequent stressors. In this study, we evaluated how individual differences in vagally mediated heart rate variability moderated the relationship between childhood maltreatment and grief among a sample of individuals experiencing a stressful life event (i.e., spousal bereavement) over time. Data were collected at approximately 3, 4.5, and 6.5 months after the death of a spouse (n = 130). Heart rate variability moderated the relationship between childhood maltreatment and grief symptoms over time (b = −0.03, p < .001), such that among individuals with more severe experiences of childhood maltreatment, those with higher heart rate variability had a faster recovery from grief than those with low heart rate variability. This research highlights an overall pattern of resilience among older adult's following spousal bereavement, as well as the relationships between childhood maltreatment, heart rate variability, and differential responses to grief following the loss of a spouse. Public Significance StatementChildhood maltreatment and heart rate variability may be related to differential responses to grief among bereaved spouses over time. Among bereaved spouses with a history of childhood maltreatment, those with higher heart rate variability experienced faster recovery from grief symptoms than bereaved spouses with lower heart rate variability. These findings suggest a pathway to intervention may include increased heart rate variability to mitigate the relationship between adverse childhood experiences and adjustment to stressors later in life, particularly among older adults.
