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. The exploratory factor analysis (EFA) extracted an internally consistent three-factor solution with 13 items: (1) HIV activist identity and commitment, orientation towards (2) day-to-day, and (3) structural activism. The Cronbach's alpha value was 0.91, and intra-class correlation coefficient for test-retest reliability was 0.86. Stigma-related (prejudice and discrimination intent) and clinical practice (comfort in performing clinical tasks with key populations and knowledge about HIV pre-exposure prophylaxis) measures supported the construct validity of the scale. The study provided concise, structurally valid, and reliable measures to evaluate HIV activism among clinicians.

RESUMEN: El activismo del VIH tiene una larga historia de avanzar el tratamiento del VIH y es crítico para desmantelar el estigma relacionado al VIH. Este estudio evaluó la calidad psicométrica de la Escala de Identidad, Compromiso y Orientación de Activistas del VIH (HAICOS) para evaluar la propensión de los médicos hacia el activismo del VIH en Malasia. Desde noviembre del 2022 hasta marzo del 2023, 74 médicos generales y de atención primaria en Malasia participaron en este estudio. El análisis factorial exploratorio (AFE) extrajo una solución de tres factores internamente consistente con 13 ítems: (1) identidad y compromiso del activismo del VIH; orientación hacia (2) el activismo cotidiano y (3) el activismo estructural. El valor alfa de Cronbach fue de 0.91 y el coeficiente de correlación intraclase para la confiabilidad prueba-reprueba fue de 0.86. Las medidas relacionadas con el estigma (prejuicio e intención de discriminación) y la práctica clínica (comodidad realizando tareas clínicas con poblaciones claves y conocimiento sobre la profilaxis pre-exposición del VIH) respaldaron la validez de constructo de la escala. El estudio proporcionó medidas concisas, estructuralmente válidas y confiables para evaluar el activismo de VIH entre los médicos.

"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. In 2021, 34 Malaysian participants representing key populations and PLWH engaged in a photovoice study designed to qualitatively explore their experiences with and hopes for doctor interactions. Many participants reported stigma from their doctors, perceiving that doctors view them as not normal, sinful, misguided, and incapable. Several emphasized that they wear figurative masks to conceal aspects of themselves from doctors. Yet, many also remain hopeful for constructive relationships with doctors. They want their doctors to know that they are bright, capable, kind, and valuable. Interventions are needed to address stigma among doctors working in contexts with strong structural stigma.

RESUMEN: El estigma en los ambientes de atención médica es una barrera perniciosa en la prevención y el tratamiento del VIH. Investigaciones anteriores han documentado un estigma sustancial hacia los grupos de población clave y las personas que viven con el VIH (PLWH por sus siglas en inglés) entre los médicos de Malasia. Sin embargo, las perspectivas de los grupos de población clave y las PLWH en Malasia siguen sin estudiarse. En 2021, 34 participantes que representaban los grupos de población clave y PLWH en Malasia participaron en un estudio de fotovoz diseñado para explorar cualitativamente sus experiencias y esperanzas en las interacciones con los médicos. Muchos participantes describieron el estigma de sus médicos, percibiendo que los médicos los ven como no normales, pecaminosos, equivocados e incapaces. Varios enfatizaron que usan máscaras figurativas para ocultar aspectos de ellos mismos a los médicos. Sin embargo, muchos también mantienen la esperanza de tener relaciones constructivas con los médicos. Quieren que sus médicos sepan que son inteligentes, capaces, amables y valiosos. Se necesitan intervenciones para abordar el estigma estructural entre los médicos que trabajan en la prevención y el tratamiento del VIH.

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. The current study describes the methods and evaluation of an online, asynchronous photovoice project conducted with 34 members of key populations and PLWH in Malaysia in 2021. A HIPAA-compliant website incorporating a series of instructional videos was created to facilitate participant engagement and data collection. Quantitative and qualitative indicators suggest that participants found the project to be highly acceptable and feasible. Online, asynchronous photovoice methods hold potential for increasing the scale of this powerful and versatile qualitative research method with key populations and PLWH.

RESUMEN: La fotovoz es un método cualitativo orientado a la acción que usa fotografía y narración de historias. Aunque la fotovoz produce una poderosa forma de datos que se puede utilizar para la investigación, la intervención y la promoción, podría decirse que ha sido poca aplicada en la investigación del VIH. Los métodos de fotovoz asincrónicos en línea representan una alternativa prometedora a los métodos en persona tradicionales, pero aún no se ha explorado su aceptabilidad y viabilidad con los grupos de población clave y las personas que viven con el VIH (PLWH por sus siglas en inglés). El estudio actual describe los métodos y la evaluación de un proyecto de fotovoz asincrónico en línea realizado con 34 miembros de grupos de población clave y PLWH en Malasia en 2021. Se creó un sitio web compatible con HIPAA que incorpora una serie de videos instructivos para facilitar la participación y la recopilación de datos. Los indicadores cuantitativos y cualitativos sugieren que los participantes encontraron el proyecto altamente aceptable y realizable. La fotovoz asincrónica en línea es un poderoso y versátil método cualitativo de investigación la cual tiene potencial para usarse más con los grupos de población clave y PLWH.

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

Objective: 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. Methods: Practicing physicians who were aged 18 years or older and had internet access participated in asynchronous online focus groups. Results: Barriers to Project ECHO were conflicting priorities, time constraints, and technology. Facilitators included content and format, dedicated time, asynchronized flexible programming, incentives, and ensuring technology was available. Conclusion: Project ECHO is a promising intervention that can increase physicians' knowledge and skill set in specialty medicine during the COVID-19 pandemic. Interventionists in Malaysia in particular, but also in general, should consider these barriers and facilitators when developing Project ECHO as they may aid in developing a more robust program and increase participation.

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. OBJECTIVES: The purpose of this article is to evaluate and compare different cluster enumeration techniques. RESEARCH DESIGN: Study I demonstrates how recently proposed resampling methods result in no precise number of clusters on which all fit statistics agree. We recommend the pre-processing method in Study II as an alternative. Both studies used nationally representative data on working memory, cognitive flexibility, and inhibitory control. CONCLUSIONS: The data plus priors method shows promise to address inconsistencies among fit measures and help applied researchers using finite mixture models in the future.

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. RESEARCH DESIGN: A detailed conceptual introduction of neural networks is provided, as well as an illustration of selection of hyperparameters to estimate GPS. An example from public health and nutrition literature uses residential distance as a treatment variable to illustrate how neural networks can be used in a propensity score analysis to estimate a dose-response function of grocery spending behaviors. RESULTS: We found substantially higher correlations and lower mean squared error values after comparing true GPS with the scores estimated by neural networks. The implication is that more selection bias was removed using GPS estimated with neural networks than using GPS estimated with classical regression. CONCLUSIONS: This study proposes a new methodological procedure, neural networks, to estimate GPS. Neural networks are not sensitive to the assumptions of linear regression and other parametric models and have been shown to be a contender against parametric approaches to estimate propensity scores for continuous treatments.

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. Participants included 358 PLWH aged 18-35 years from Georgia, United States. At baseline, participants completed measures of internalized and enacted stigma, depressive symptoms, and substance use severity. Substance use was additionally tested with urinalysis. Following baseline, participants reported their use of substances before sex for 28 days through daily text messaging. Data were analyzed using path analysis in R. On average, participants tested positive for 1.24 (range: 0-6) substances used, reported moderate to high risk on 2.01 (range: 0-8) substances, and reported using substances 1.57 (range: 0-20) times before sex over 28 days. Internalized stigma and enacted stigma were associated with greater depressive symptoms, and depressive symptoms were associated with all three indicators of substance use. Moreover, the indirect effects between internalized and enacted stigma with indicators of substance use were significant, suggesting that depressive symptoms partially mediated associations between stigma and substance use. Interventions may be needed to address both stigma and depressive symptoms among PLWH to reduce substance use and support HIV treatment and prevention efforts.
