The effects of childhood emotional abuse on aggressive obsessions among patients with obsessive compulsive disorder may be mediated by symptoms of depression and anxiety

Clinical features of obsessive-compulsive disorder among individuals who experience health-related obsessive-compulsive symptoms

BACKGROUND

While some obsessive-compulsive disorder (OCD) phenotypes are well-established and better understood, it is unclear whether the presence of health-related obsessive-compulsive symptoms (OCS) is associated with specific clinical characteristics. We aimed to investigate whether OCS involving concerns with illness, diseases, body parts or aspects of appearance (i.e. health-related OCS) are associated with differences in demographics, experience of stressful life events, clinical severity, clinical course, endorsement of established OCD dimensions, and psychiatric comorbidities.

METHODS

Individuals (N = 1001) with a clinical diagnosis of OCD (M = 34.85, SD = 12.99) completed a questionnaire battery assessing clinical course (age at symptom onset, age at diagnosis, duration of illness), total and dimensional symptom severity, and psychiatric comorbidities. We ran initial univariate, and follow-up multivariate analyses where appropriate, to compare individuals reporting health-related OCS with those not reporting health-related OCS in terms of demographics, symptom severity and clinical course, OCD symptom dimensions, and psychiatric comorbidities.

RESULTS

The presence of health-related OCS was associated with higher severity of contamination, hoarding and harm symptoms. Additionally, those with health-related OCS displayed significantly lower symptom insight, increased incidence of hypochondriasis, panic disorder and anxiety, and lower depression symptoms. Overall OCD symptom severity and clinical course did not differ between participants with and without health-related OCS.

IMPLICATIONS

These novel findings provide clinicians with an enhanced understanding of health-related OCS in order to guide assessment and allow for more targeted treatment planning. Future investigations may examine the effectiveness of specialised treatment methods which target underlying clinical features of health-related OCS.

The Relationship between Childhood Trauma Experiences and Psychotic Vulnerability in Obsessive Compulsive Disorder: An Italian Cross-Sectional Study

People with obsessive compulsive disorder (OCD) are at increased risk of developing psychotic disorders; yet little is known about specific clinical features which might hint at this vulnerability. The present study was aimed at elucidating the pathophysiological mechanism linking OCD to psychosis through the investigation of childhood trauma experiences in adolescents and adults with OCD. One hundred outpatients, aged between 12 and 65 years old, were administered the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and its Child version (CY-BOCS), as well as the Childhood Trauma Questionnaire (CTQ); Cognitive-Perceptual basic symptoms (COPER) and high-risk criterion Cognitive Disturbances (COGDIS) were assessed in the study sample. Greater childhood trauma experiences were found to predict psychotic vulnerability (p = 0.018), as well as more severe OCD symptoms (p = 0.010) and an earlier age of OCD onset (p = 0.050). Participants with psychotic vulnerability reported higher scores on childhood trauma experiences (p = 0.02), specifically in the emotional neglect domain (p = 0.01). In turn, emotional neglect and psychotic vulnerability were found higher in the pediatric group than in the adult group (p = 0.01). Our findings suggest that childhood trauma in people with OCD may represent an indicator of psychotic vulnerability, especially in those with an earlier OCD onset. Research on the pathogenic pathways linking trauma, OCD, and psychosis is needed.

Childhood emotional maltreatment, maladaptive coping and obsessive-compulsive symptoms in patients with obsessive-compulsive disorder

Previous studies have reported childhood emotional maltreatment (CEM) to be associated with specific obsessive-compulsive (OC) symptoms, but maladaptive coping, which may be the underlying mechanism in this relationship, has not been evaluated yet. Thus, the present study aimed to examine the effects of CEM on the OC symptoms of responsibility for harm and unacceptable thoughts, as well as obsessive-compulsive disorder (OCD) severity, through maladaptive coping, including cognitive avoidance, experiential avoidance and emotional suppression in OCD patients (n = 360). The results showed that CEM had direct effects, as well as indirect effects via cognitive and experiential avoidance and emotional suppression, on responsibility for harm and unacceptable thoughts. In addition, the indirect effect of CEM on OCD severity was significantly mediated by the roles of cognitive avoidance and experiential avoidance. The present study adds new literature to evidence indicating the role of early childhood events in developing and maintaining OCD in which adverse maladaptive coping related to unpleasant childhood abuse plays an important role in OCD. More precisely, OCD patients who experience a history of CEM may further use maladaptive coping to cope with their distress and subsequently experience responsibility for harm, unacceptable thoughts and severe OCD.

The effect of childhood trauma on the severity of obsessive-compulsive symptoms: A systematic review

BACKGROUND

Childhood trauma is associated with a range of psychiatric disorders, including obsessive-compulsive disorder (OCD). However, our understanding of the different types of childhood trauma and its impact on the different types and severity of obsessive-compulsive symptoms (OCS) is still in its infancy.

AIMS

We conducted a systematic review to synthesise the current knowledge on the possible relationships between childhood trauma and obsessive-compulsive symptoms in clinical and non-clinical populations.

METHODS

We systematically searched four electronic databases for studies reporting on childhood trauma and OCS severity. Subsequently, we qualitatively synthesised results of eligible studies and effect sizes were also calculated.

RESULTS

Twenty-four studies were included in this systematic review. Most studies used OCD samples (k = 16), with a few studies using a sample comprising of a range of psychiatric disorders (k = 6) and some studies using a general community sample (k = 2). Overall, there was support for a significant relationship between childhood trauma and OCS severity (8 out of 16 of the studies using OCD clinical samples, both studies using general population samples, and 5 out of 6 studies used mixed psychiatric samples).

CONCLUSIONS

We found evidence of a significant relationship between exposure to childhood trauma and OCS severity across clinical and non-clinical populations. Our results also suggest that a range rather than a single type of childhood trauma was associated with OCD.

Association between relational trauma and empathy among male offenders in China

BACKGROUND

Offenders are more likely than the general population to have experienced relationship trauma. They are also more likely to have lower empathy. To date, relationships between historical trauma and later empathic states have not been examined among offenders.

AIMS

To explore the association between history of trauma in close personal relationships and empathy among offenders. Our research question is: Is such relational trauma associated with self-rated impairments in empathy?

METHODS

All men with a primary school education and above at a single all-male prison in Jiangsu Province in China were invited to participate. The self-reported Interpersonal Reactivity Index was used to evaluate empathy, and the Brief Betrayal Trauma Survey was to explore interpersonal trauma and classify such experiences.

RESULTS

Interpersonal trauma was associated with higher personal distress and lower empathic concern among men reporting relational trauma in adulthood, but only higher personal distress when the trauma reported was in childhood. Non-relational trauma was associated with higher empathic concern. Cognitive aspects of empathy varied little between groups.

CONCLUSIONS

Our findings add to the existing literature by making distinctions between the types of trauma and the age of key experience in its relationship to self-reported empathy. The differences found suggest that it may be helpful to consider planning any trauma-related interventions differently according to the type and age of trauma experiences.

Association Between Childhood Maltreatment and Symptoms of Obsessive-Compulsive Disorder: A Meta-Analysis

Background: Previous studies have indicated that childhood maltreatment (CM) may potentially influence the clinical symptomatology of obsessive-compulsive disorder (OCD). Here, we aimed to quantify the relationship between CM and obsessive-compulsive symptoms (OCS) and depressive symptoms in OCD through a meta-analysis. Method: We searched PubMed, Embase, Cochrane Library, and PsycARTICLES databases for articles reporting the association between CM and OCD on April 15, 2020. Random-effect models were used to quantify the relationship between CM and the severity of OCS and depressive symptoms in OCD. Results: Ten records with 1,611 OCD patients were included in the meta-analysis. The results revealed that CM is positively correlated with the severity of OCS [r = 0.10, 95%Confidence Interval (CI): 0.01-0.19, P = 0.04] as well as depressive symptoms in OCD (r = 0.15, 95%CI: 0.07-0.24, P = 0.0002). For the subtypes of CM, childhood emotional abuse (CEA) and childhood sexual abuse (CSA) was related with the severity of OCS (r = 0.11, 95%CI: 0.03-0.19, P = 0.009) and obsession (r = 0.13, 95%CI: 0.03-0.23, P = 0.01), respectively. Conclusion: Our meta-analysis indicates that OCD patients who suffered more CM may exhibit more severe OCS and depressive symptoms.
