Evaluating a maladaptive personality-informed model of social support and post-traumatic stress disorder.

BACKGROUND: Social support is a robust predictor of post-traumatic stress disorder (PTSD). Although the inverse relationship between perceived social support and PTSD (social causation model) is supported, less is understood about the antecedents of the social causation model. Further, there is limited research in non-Western psychiatric populations that experience elevated rates of trauma and PTSD (e.g., mood disorders). The present study evaluated whether cumulative traumatic life events influenced current PTSD symptoms through maladaptive personality traits and perceptions of social support among Asian patients with mood disorders. METHODS: A total of 200 Asian patients (77.5 % Chinese) with mood disorders were assessed for maladaptive personality traits, perceptions of social support, cumulative traumatic life events, PTSD, and depressive symptoms. Structural equation modelling was conducted to evaluate the extended social causation model. RESULTS: The extended social causation model demonstrated acceptable fit to the data (Comparative Fit Index [CFI] = 0.90; absolute Root Mean Square Error of Approximation [RMSEA] = 0.08). There were significant indirect effects of cumulative traumatic life events on current PTSD symptoms (ß = 0.29, p < .001; 85 % variance explained) and depressive symptoms (ß = 0.28, p < .001; 69 % variance explained). LIMITATIONS: Results may not be generalizable beyond the Singapore population due to the socio-cultural and environmental context. CONCLUSIONS: The present findings provide conceptual support for a maladaptive personality-informed model of social support and PTSD, which could better inform trauma-focused interventions in preventing and treating the debilitating effects of PTSD in psychiatric populations.

Pathological personality explains individual differences in global emotion dysregulation within the pathway between child maltreatment and severe depressive symptoms.

OBJECTIVE: Global emotion dysregulation mediates the relationship between child maltreatment and severe depressive symptoms; however, there is a lack of research on maladaptive personality traits and their contribution to individual differences in global emotion dysregulation within this conceptual model. The present study tested a preliminary serial mediation model where maladaptive personality traits and global emotion dysregulation mediate the relationship between child maltreatment and severe depressive symptoms. METHOD: A total of 200 patients with mood disorders (Mage = 36.5 years; 54% females) were assessed for maladaptive personality traits (Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders [5th ed.] Brief Form), global emotion dysregulation (Difficulties in Emotion Regulation Scale-Short), childhood trauma (Childhood Trauma Questionnaire), and depressive symptoms (Patient Health Questionnaire-9). RESULTS: Ordinary least squares regression and partial least squares-structural equation modeling revealed a consistent and significant indirect effect of child maltreatment on severe depressive symptoms through negative affectivity, detachment, psychoticism, and global emotion dysregulation. Among child maltreatment types, only emotional abuse had a significant indirect effect on severe depressive symptoms through maladaptive personality traits and global emotion dysregulation, b = 0.50, SE = 0.09, 95% confidence intervals [0.326, 0.694] after controlling for age, gender, and remaining types of child maltreatment. CONCLUSIONS: Findings support the view that maladaptive personality traits shed important insights on individual differences in global emotion dysregulation, and this information could aid clinical formulation and treatment of childhood adversity-related psychopathology.

Emotional urgency predicts bipolar symptoms, severity, and suicide attempt better than non-emotional impulsivity: a cross-sectional study.

Introduction: Emotional urgency is an emotion-based subdimension of trait impulsivity that is more clinically relevant to psychopathology and disorders of emotion dysfunction than non-emotional subdimensions (i.e., lack of perseverance, sensation seeking, lack of premeditation). However, few studies have examined the relative effects of emotional urgency in bipolar disorder. This cross-sectional study aimed to establish the clinical relevance of emotional urgency in bipolar disorders by (1) explicating clinically relevant correlates of emotional urgency and (2) comparing its effects against non-emotional impulsivity subdimensions. Methods and results: A total of 150 individuals with bipolar disorder were recruited between October 2021 and January 2023. Zero-order correlations found that emotional urgency had the greatest effect on bipolar symptoms (r = 0.37 to 0.44). Multiple two-step hierarchical regression models showed that (1) positive urgency predicted past manic symptomology and dysfunction severity (b = 1.94, p < 0.001 and 0.35 p < 0.05, respectively), (2) negative urgency predicted current depression severity, and (3) non-emotional facets of impulsivity had smaller effects on bipolar symptoms and dysfunction by contrast, and were non-significant factors in the final step of all regression models (b < 0.30, ns); Those who had a history of attempted suicide had significantly greater levels of emotional urgency (Cohen's d = -0.63). Discussion: Notwithstanding the study's limitations, our findings expand status quo knowledge beyond the perennial relationship between non-emotion-based impulsivity and bipolar disorder and its implications.

Sleep disturbance as transdiagnostic mediator between adverse childhood experiences and psychopathology in children and adolescents: A structural equation modeling meta-analysis.

Background: Increasing research efforts have focused on understanding why some individuals develop severe psychopathology after exposure to adverse childhood experiences (ACEs). Sleep disturbances (insomnia, nightmares, and sleep disorders) are prevalent sequelae of ACEs and associated with psychopathology; however, there is no meta-analytic evidence on whether sleep disturbance functions as a transdiagnostic mediator in the relationship between ACEs and psychopathology (internalizing/externalizing disorders and psychosis) in children and adolescents. Methods: Systematic searches in three databases (PubMed; PsycINFO; Web of Science) identified 98 articles (N = 402,718; age range 1-17 years) and the present study used a novel two-stage meta-analytic structural equation model to investigate whether ACEs predict psychopathology through sleep disturbance. Subgroup analyses determined potential biases due to study design (cross-sectional vs. longitudinal) and geographical differences (Western vs. non-Western countries). Sensitivity analyses evaluated the influence of early childhood (<5 years old) and overlapping symptoms (i.e., nightmares and trauma symptoms) on model stability. Results: The pooled correlations among ACEs, sleep disturbance, and psychopathology were significant; the effect sizes ranged from moderate to high (r = 0.21 to r = 0.29). The indirect effect from ACEs via sleep disturbance to psychopathology was significant (ß = 0.05, 95% CI [0.04, 0.06]). The direct effect of ACEs on psychopathology was significant (ß = 0.18, 95% CI 0.13-0.24). Subgroup analyses revealed larger effects for cross-sectional studies than longitudinal studies (Δ χ2 (3) = 9.71, p = 0.021). Sensitivity analyses revealed stable and consistent results. Conclusions: The present meta-analytic results indicate that sleep disturbance is a transdiagnostic mediator in the relationship between ACEs and psychopathology among children and adolescents. Further research is required to determine the synergistic effects between sleep disturbance and other risk mechanisms, and elucidate the complex pathways that lead to disorder in the aftermath of childhood adversities.

Analysis and Interpretation of Metaphors: Exploring Young Adults' Subjective Experiences With Depression.

The aim of this study was to provide a cross-cultural exploration of how young adults with depression use metaphors to describe their illness experiences. Data were collected in semi-structured interviews, designed to capture rich and detailed descriptions of participants' firsthand narrative experiences of depression and how they make sense of depression. Thirty-three participant interview data were analyzed, using a combination of deductive and inductive approaches. The analysis resulted in extracting five major themes with sub-themes, which detail the diversity and vividness of metaphorical expressions embedded in participants' accounts and produce insights and a richer picture of the depression experience. Metaphors play a pivotal role in providing a rich resource that young adults rely on, to construct meaningful accounts about their illness. This highlights the importance of a metaphor-enriched perspective in research as well as in clinical practice, particularly in a multicultural health care setting.

A reduced state of being: The role of culture in illness perceptions of young adults diagnosed with depressive disorders in Singapore.

Illness perceptions form a key part of common-sense models which are used widely to explain variations in patient behaviours in healthcare. Despite the pervasiveness of depressive disorders worldwide and in young adults, illness perceptions of depressive disorders have not yet been well understood. Moreover, while a high proportion of cases of depressive disorders reside in South-east Asia, few have explored illness perceptions that are culturally relevant to this region. To address these limitations, this study aimed to understand illness perceptions of young adults diagnosed with depressive disorders. Face-to-face semi-structured interviews were conducted among Chinese, Malay, and Indian young adults aged 20 to 35 years old, who were seeking treatment at a psychiatric hospital. Data reached saturation after 33 interviews (10 to 12 interviews per ethnic group) and five themes emerged from the thematic analysis: 1) A reduced state of being experienced at a point of goal disengagement, 2) the accumulation of chronic stressors in a system that demands success and discourages the pursuit of personally meaningful goals, 3) a wide range of symptoms that are uncontrollable and disabling, 4) poor decision making resulting in wasted opportunities, with some positive takeaways, and 5) accepting the chronicity of depression. Young adults typically experienced depression as a reduced state of being and it was thought of cognitively as an entity that may be a part of or separate from the self. Over and beyond these aspects of cognitive representations was the emergence of themes depicting conflicts and dilemmas between the self and the social environment that threatened self-identity and autonomy. Addressing these conflicts in therapy would therefore be of utmost relevance for young adults recovering from depressive disorders in the local setting.
