Moderated Mediation Analysis of Structural Stigma and Suicidal Ideation and Behaviors Among Sexual and Gender Minority Adults

Purpose: This study aimed to conduct a moderated mediation analysis to understand further the complex pathways through which structural stigma in the form of transgender sports bans was associated with suicidal ideation and behaviors among sexual and gender minority (SGM) adults. Methods: A cross-sectional survey of 1033 adults who identified as SGM from across the 50 U.S. states and Washington, DC was conducted between January 28 and February 7, 2022. Distal discrimination distress was the mediation variable; individual resilience and social resources were the moderation variables. Familiarity with transgender sports bans represented structural stigma. The conditional process analysis was applied to build a moderated mediation model. Both conditional direct and indirect effects were computed by estimated coefficients. All models were based on linear regression. Results: Our final model explained nearly half (46%) of the variation in suicidal ideation and behaviors between those SGM adults familiar and those not familiar with transgender sports bans. Social resources significantly moderated the conditional indirect effect of distal discrimination distress (adjusted estimate = -0.23; 95% confidence interval = -0.37 to -0.08). Conclusion: Both discrimination distress and social resources influenced the association between structural stigma as measured by familiarity with transgender sports bans and suicidal ideation and behaviors among SGM adults. Findings support the need for future research examining the pathway between structural stigma and suicidal ideation and behaviors among SGM adults and how minority stress, social safety, and other constructs shape this pathway.

Symptoms characteristics of personality disorders associated with suicidal ideation and behaviors in a clinical sample of adolescents with a depressive disorder

Introduction

Pathological personality traits have repeatedly been identified as important risk factors for suicidal ideation and behaviors. Moreover, impulsive-aggressive traits, have shown a consistent association with suicidal behaviors across the lifespan. Adolescence represents a critical period for the emergence of different personality traits, mood disorders, and suicidal behaviors, but the relationship between these variables remain poorly understood.

Methods

These variables were examined in a cross-sectional case-control design involving three groups: 30 adolescents with a depressive disorder and past suicide attempt (Mean Age = 16.2, Females = 26), 38 adolescents with a depressive disorder but without past suicide attempt (Mean age = 16.0, Females = 29), and 34 healthy adolescent controls (Mean age = 15.2, Females = 22). Suicidal ideations were indexed using Suicidal Behavior Questionnaire (SBQ-R), psychiatric disorder assessed using a semi-structured questionnaire (K-SADS-PL), depressive symptoms with the Beck Depressive Inventory (BDI), symptoms characteristics of personality disorders with the Scheduled Clinical Interview for the DSM-IV (SCID-II) screening questionnaire, and impulsivity with the Barratt Impulsivesness Scale (BIS).

Results

Findings showed that impulsivity (F = 11.0, p < 0.0001) and antisocial symptoms characteristics of personality disorders (p < 0.001, d = 0.70) displayed the most robust association with adolescent suicide attempts. Borderline symptoms characteristics of personality disorders did not discriminate attempters from non-attempters but presented high correlations with suicidal ideation and depression severity. In an item-wise analysis, suicide attempt status was uniquely correlated with symptoms characteristics of an antisocial personality disorder. Suicide attempt status also correlated with non-suicidal self-injury and a chronic feeling of emptiness.

Discussion

The caveats of this cross-sectional study include the stability of symptoms characteristics of personality disorders in adolescence and the limited sample size. In sum, suicidal behaviors were characteristically correlated with increased impulsivity and antisocial symptoms characteristics of personality disorders, but other symptoms characteristics of personality disorders were relevant to adolescent depression and suicidal ideation. Understanding the emergence of symptoms characteristics of personality disorders and suicidal behaviors in a developmental context can ultimately inform not only the neurobiological origin of suicidal behaviors, but also provide new avenues for early detection and intervention.
