Diagnostic sequence of cocaine use disorder in relation to other mental health conditions among college students

Abstract

Objective: Cocaine use is increasing. Comorbidities and diagnostic sequencing are needed among college students to inform treatment of cocaine use disorder (CUD). Method: Using electronic medical records from the psychiatric clinic at the student health care center of a large, public university from 2005 to 2015, patients diagnosed with CUD were identified. Their top mental health conditions were identified and assessed to see whether the first diagnosis of these conditions was made (1) before, (2) at the same time as, or (3) after the first diagnosis of CUD. Results: Among the 50 CUD patients, their most common mental health comorbidities were alcohol use disorder, anxiety, depression, and cannabis use disorder. Anxiety and depression were likely to be diagnosed before CUD; alcohol and cannabis use disorders were likely to be diagnosed concurrently with CUD. Conclusion: Diagnostic sequencing can be used to inform screening, workup, and treatment for patients with CUD.     

Knowledge of Suicide Risk Factors,But Not Suicide Ideation Severity,Is Greater Among College Students Who Viewed 13 Reasons Why

Abstract

Objective: To test associations between viewing 13 Reasons Why, Season 1 and past week suicide ideation severity, behavior risk, stigma, and knowledge in college students. To explore whether personal exposure to suicide and depressive symptom severity moderated these associations. Participants: Eight-hundred and eighteen college students, 64% (n?=?522) of whom watched 13 Reasons Why. Methods: Students completed surveys online. Multivariate negative binomial regressions were used to test associations between watching 13 Reasons Why and suicide-related variables, and interaction terms. Results: Suicide ideation severity and suicide behavior risk were not significantly associated with viewing 13 Reasons Why; however, there was limited statistical power to detect associations. The association between watching 13 Reasons Why and greater suicide knowledge was stronger among those who did not have personal exposure to suicide. Conclusions: 13 Reasons Why may be a platform for psychoeducation on suicide, particularly among those who do not have personal exposure.     

Deviant Peers and Adolescent Risky Behaviors: The Protective Effect of Nonverbal Display of Parental Warmth

This study examines whether nonverbal displays of parents’ warmth during an in‐lab conflict discussion mitigate the links between affiliation with deviant peers and risky behaviors. A sample of 107 youth and their parents participated in a study spanning from mid‐adolescence (T1) to late adolescence (T2). At T1, family members discussed a contentious issue, which was coded for parents’ nonverbal warmth. At T1 and T2, youth reported on their friends’ and their own risky behaviors. Fathers’ warmth moderated each prospective association between deviant peers and risky behaviors. Mothers’ warmth did not emerge as a significant moderator. Girls, in particular, benefitted from fathers’ warmth as a buffer in the trajectory from T1 risky behaviors to T2 risky behaviors and deviant peers.     

A Bayesian mixture of experts approach to covariate misclassification

This article considers misclassification of categorical covariates in the context of regression analysis; if unaccounted for, such errors usually result in mis-estimation of model parameters. With the presence of additional covariates, we exploit the fact that explicitly modelling non-differential misclassification with respect to the response leads to a mixture regression representation. Under the framework of mixture of experts, we enable the reclassification probabilities to vary with other covariates, a situation commonly caused by misclassification that is differential on certain covariates and/or by dependence between the misclassified and additional covariates. Using Bayesian inference, the mixture approach combines learning from data with external information on the magnitude of errors when it is available. In addition to proving the theoretical identifiability of the mixture of experts approach, we study the amount of efficiency loss resulting from covariate misclassification and the usefulness of external information in mitigating such loss. The method is applied to adjust for misclassification on self-reported cocaine use in the Longitudinal Studies of HIV-Associated Lung Infections and Complications.

Social and feminist design in emergency contexts: the Women’s Social Architecture Project,Cox's Bazar,Bangladesh

ABSTRACT

The rapid influx of Rohingya refugees into Cox's Bazar, Bangladesh, has led to the formation of huge camps, built on difficult terrain, short of space and with high population density. All these factors present numerous challenges to agencies seeking to provide latrines, water points, and bathing facilities. Feedback gathered from women and girls highlighted significant challenges around access, safety, privacy, and dignity, including management of personal hygiene and menstruation. Within the humanitarian community, site planning and WASH (water, sanitation and hygiene) infrastructure planning/design processes have mainly been dominated by male architects and engineers, often with gendered assumptions about the user. Acknowledging these challenges, Oxfam implemented the Women’s Social Architecture Project to work with women and adolescent girls, and female architects with a background or interest in social or feminist design and architecture, to add a different perspective into the design and siting of WASH facilities. The project has consisted of formative research with Rohingya women and girls, and design workshops with architects in which Rohingya women have co-created designs that tackle the issues they face regarding WASH facilities. This article provides an account of the progress to date, together with feedback from women and girls and the WASH Sector in Cox's Bazar ahead of the final completion of the project in June 2019.     

Minority stress in same-sex male relationships: when does it impact relationship satisfaction?

The minority stress model (Meyer, 2003) has been proposed to explain higher rates of psychopathology in lesbian, gay, and bisexual individuals. However, studies of minority stress have rarely taken into account the interface between minority stress and same-sex relationship processes. In the current study, 142 gay men in romantic relationships completed an online survey assessing minority stress constructs, relationship features, and relationship satisfaction. Minority stress was not directly related to relationship satisfaction, while commitment, trust, and support from one's partner were related to relationship satisfaction. Significant moderation effects emerged between discrimination and trust and between internalized heterosexism and commitment, indicating that trust was related to satisfaction for those who had experienced frequent discrimination, while commitment was related to satisfaction for those low in internalized heterosexism.     

Disruptions,adjustments and hopes: The impact of the COVID-19 pandemic on child well-being in five Majority World Countries

Drawing on integrated data from focus groups and diary entries, we explored the impact of the COVID-19 pandemic on child well-being for children from five Majority World Countries. We focus on the disruptions the pandemic caused, the adjustments made in response to these, and children's vision of a post-pandemic world. Underlying children's experiences of loss, boredom and concerns about educational progress, was an awareness of systemic inequalities that disadvantaged them or others in their community. Findings have implications on capturing children's voices through introspective and dialogical approaches that transcend cultures and for the development of preventive and responsive interventions during crises.     

The unique relationship between childhood sexual abuse,self-injury and suicide ideation: The mediating role of emotion dysregulation

Child sexual abuse (CSA) has serious short-term and long-term effects, including non-suicidal self-injury (NSSI) and suicidal ideation (SI). One possible thread linking CSA to NSSI and suicide risk is emotion dysregulation. The current study assessed whether facets of emotion dysregulation mediated relations of NSSI behaviours and functions, and SI. Participants (N = 121; Mean age = 18.69, age-range 18–22; 78 per cent female), college students with a history of childhood trauma, completed an online survey. Results indicated that facets of emotion dysregulation (i.e. clarity, non-acceptance) mediated the relationship between CSA and SI. CSA was associated with automatic negative reinforcement, social negative and social positive reinforcement NSSI functions, but was not associated with NSSI behaviours. Emotion dysregulation facets did not mediate the relationship between CSA and NSSI functions. Findings highlight the need to help CSA survivors have clarity and acceptance of emotional experiences to reduce SI risk. This research did not receive any specific grant from funding agencies in the public, commercial or not-for-profit sectors.
