Development and Validation of the Youth Pre-Exposure Prophylaxis (PrEP) Stigma Scale.

To date, there are no established scales to assess PrEP stigma among youth. We validated the Youth PrEP Stigma Scale within the Adolescent Trials Network P3 study (2019-2021). Data from sexual and gender minority youth (16-24 years) who were prescribed PrEP across nine domestic sites were evaluated (N = 235). Descriptive statistics, exploratory factor analysis, and correlation coefficients are reported. Results yielded a three-factor solution (PrEP Disapproval by Others, Enacted PrEP Stigma, and PrEP User Stereotypes) with strong factor loadings and Cronbach's alphas ranging from 0.83 to 0.90, suggesting excellent internal consistency. Correlations between this Scale, anticipated HIV stigma, perceived HIV risk, and disclosure of sexual identity were significant, indicating potential for robust application. Given the persistence of HIV infections among youth, stigma as a barrier to prevention, and expansion of PrEP modalities, the Youth PrEP Stigma Scale could enhance intervention and mechanistic research among youth at elevated risk for HIV acquisition.

RESUMEN: Hasta la fecha, no existen escalas establecidas para evaluar el estigma de la PrEP entre los jóvenes. Validamos la Escala de estigma de la PrEP para jóvenes dentro del estudio P3 de la Red de ensayos para adolescentes (2019­2021). Se evaluaron los datos de jóvenes de minorías sexuales y de género (16­24 años) a quienes se les recetó PrEP en nueve sitios domésticos (N = 235). Se informan estadísticas descriptivas, análisis factorial exploratorio y coeficientes de correlación. Los resultados arrojaron una solución de tres factores (desaprobación de PrEP por parte de otros, estigma de PrEP promulgado y estereotipos de usuarios de PrEP) con fuertes cargas factoriales y alfas de Cronbach que oscilan entre 0.83 y 0.90, lo que sugiere una excelente consistencia interna. Las correlaciones entre esta Escala, el estigma anticipado del VIH, el riesgo percibido del VIH y la divulgación de la identidad sexual fueron significativas, lo que indica un potencial para una aplicación sólida. Dada la persistencia de las infecciones por el VIH entre los jóvenes, el estigma como una barrera para la prevención y la expansión de las modalidades de PrEP, la Escala de estigma de la PrEP para jóvenes podría mejorar la intervención y la investigación mecánica entre los jóvenes con un riesgo elevado de contraer el VIH.

Validation of HIV Pre-Exposure Prophylaxis (PrEP) Medication Scales with Youth on PrEP: PrEP Confidence Scale and PrEP Difficulties Scale.

Pre-exposure prophylaxis (PrEP) is a lifesaving medical intervention that protects against human immunodeficiency virus (HIV), but to date, PrEP uptake has been limited. PrEP utilization and adherence among youth, including stigmatized and highly vulnerable young sexual and gender minorities, have been exceptionally low across all regions, leading to preventable HIV transmission. Considering the scientific value of measuring and understanding predictors or associations of PrEP adherence, our study team validated two scales: a PrEP Difficulties Scale and a PrEP Confidence Scale tested within the Adolescent Trials Network P3 study (2019-2021). Data from sexual and gender minorities who were prescribed PrEP across nine domestic sites were evaluated (N = 235). Descriptive statistics, exploratory factor analysis, and correlation coefficients are reported herein. Results for the PrEP Difficulties Scale yielded a four-factor solution (Disclosure, Health Effects, Logistics, and Cost), and results for the PrEP Confidence Scale produced a three-factor solution (Scheduling, Distraction, and Planning). Factor loadings and Cronbach's alphas suggested good internal consistency for both scales. PrEP Confidence Scale subscales were correlated with PrEP adherence, and subscales of both scales were associated with dimensions of social support and PrEP-related stigma. Given the persistence of preventable HIV infections among key populations, multi-level barriers and facilitators to medication adherence, and expansion of PrEP modalities, the PrEP Difficulties Scale and PrEP Confidence Scale have the potential to enhance intervention, exploratory, and mechanistic HIV prevention research.
