enCompass: evaluation of a community-based substance use disorder stigma intervention.

Introduction: Stigma within communities is pervasive and a barrier to substance use disorder (SUD) treatment. The current proof-of-concept study evaluated , a community-based SUD knowledge and stigma intervention.

Methods: In 2021, 22 trainings were offered to community members in partnership with the Ohio Governor's RecoveryOhio initiative to 22 Ohio counties with high numbers of overdose deaths.

HIV Activist Identity, Commitment, and Orientation Scale (HAICOS): Psychometric Evaluation to Assess Clinician's Propensity Towards HIV Activism in Malaysia.

HIV activism has a long history of advancing HIV treatment and is critical in dismantling HIV-related stigma. This study evaluated the psychometric quality of the HIV Activist Identity, Commitment, and Orientation Scale (HAICOS) to assess clinicians' propensity towards HIV activism in Malaysia. From November 2022 to March 2023, 74 general practitioners and primary care physicians in Malaysia participated in the study.

"I want the doctors to know that I am as bright as a candle": : Experiences with and Hopes for Doctor Interactions Among Malaysian Key Populations and People Living with HIV.

Stigma in healthcare settings is a pernicious barrier to HIV prevention and treatment in contexts with strong HIV-related structural stigma. Previous work has documented substantial stigma towards key populations and people living with HIV (PLWH) among Malaysian doctors. The perspectives of Malaysian key populations and PLWH, however, remain understudied.

Acceptability and Feasibility of Online, Asynchronous Photovoice with Key Populations and People Living with HIV.

Photovoice is an action-oriented qualitative method involving photography and story-telling. Although photovoice yields a powerful form of data that can be leveraged for research, intervention, and advocacy, it has arguably been underutilized within HIV research. Online, asynchronous photovoice methods represent a promising alternative to traditional in-person methods, yet their acceptability and feasibility with key populations and people living with HIV (PLWH) have yet to be explored.

Barriers and Facilitators to Implementing Project ECHO in Malaysia During the COVID-19 Pandemic.

In Malaysia, HIV is concentrated among key populations who experience barriers to care due to stigma and healthcare discrimination. The COVID-19 pandemic has increased barriers to healthcare. Project ECHO (Extension for Community Healthcare Outcomes) is a transformative tele-education strategy that could improve HIV prevention and treatment.

Finite Mixture Modeling for Program Evaluation: Resampling and Pre-processing Approaches.

Background: Finite mixture models cluster individuals into latent subgroups based on observed traits. However, inaccurate enumeration of clusters can have lasting implications on policy decisions and allocations of resources. Applied and methodological researchers accept no obvious best model fit statistic, and different measures could suggest different numbers of latent clusters.

Neural Networks to Estimate Generalized Propensity Scores for Continuous Treatment Doses.

Background: The generalized propensity score (GPS) addresses selection bias due to observed confounding variables and provides a means to demonstrate causality of continuous treatment doses with propensity score analyses. Estimating the GPS with parametric models obliges researchers to meet improbable conditions such as correct model specification, normal distribution of variables, and large sample sizes.

Objectives: The purpose of this Monte Carlo simulation study is to examine the performance of neural networks as compared to full factorial regression models to estimate GPS in the presence of Gaussian and skewed treatment doses and small to moderate sample sizes.

HIV Stigma, Depressive Symptoms, and Substance Use.

Substance use problems undermine HIV treatment and secondary prevention efforts. Research is needed to better understand predictors of substance use among people living with HIV (PLWH). We examined whether internalized stigma and enacted HIV stigma are associated with three indicators of substance use among PLWH, including numbers of (1) substances used, (2) substances used at moderate to high risk, and (3) times substances were used before sex, through the mediator of depressive symptoms.
