Validation of a Brief Internalized Sex-work Stigma Scale among Female Sex Workers in Kenya

Mixed-methods protocol for the WiSSPr study: Women in Sex work, Stigma and psychosocial barriers to Pre-exposure prophylaxis in Zambia

INTRODUCTION

Women engaging in sex work (WESW) have 21 times the risk of HIV acquisition compared with the general population. However, accessing HIV pre-exposure prophylaxis (PrEP) remains challenging, and PrEP initiation and persistence are low due to stigma and related psychosocial factors. The WiSSPr (Women in Sex work, Stigma and PrEP) study aims to (1) estimate the effect of multiple stigmas on PrEP initiation and persistence and (2) qualitatively explore the enablers and barriers to PrEP use for WESW in Lusaka, Zambia.

METHODS AND ANALYSIS

WiSSPr is a prospective observational cohort study grounded in community-based participatory research principles with a community advisory board (CAB) of key population (KP) civil society organi sations (KP-CSOs) and the Ministry of Health (MoH). We will administer a one-time psychosocial survey vetted by the CAB and follow 300 WESW in the electronic medical record for three months to measure PrEP initiation (#/% ever taking PrEP) and persistence (immediate discontinuation and a medication possession ratio). We will conduct in-depth interviews with a purposive sample of 18 women, including 12 WESW and 6 peer navigators who support routine HIV screening and PrEP delivery, in two community hubs serving KPs since October 2021. We seek to value KP communities as equal contributors to the knowledge production process by actively engaging KP-CSOs throughout the research process. Expected outcomes include quantitative measures of PrEP initiation and persistence among WESW, and qualitative insights into the enablers and barriers to PrEP use informed by participants' lived experiences.

ETHICS AND DISSEMINATION

WiSSPr was approved by the Institutional Review Boards of the University of Zambia (#3650-2023) and University of North Carolina (#22-3147). Participants must give written informed consent. Findings will be disseminated to the CAB, who will determine how to relay them to the community and stakeholders.

Development of the Chinese Version of the Physician Internalized Occupational Stigma Scale (PIOSS)

Background/Objective

Internalized occupational stigma may develop in physicians as a result of their identification with the public negative labels and stereotypes about them, and then internalization of them as a part of their self-concept. This study aims to develop the Physician Internalized Occupational Stigma Scale (PIOSS) and to examine its reliability and validity.

Methods

In study 1, the initial scale was used to investigate 356 physicians. While in study 2, a total of 346 physicians were investigated with the survey tools named the PIOSS, the Career Commitment Scale (CCS), the Workplace Well-Being Scale (WWBS), the Scale for the Doctor with Patient-doctor Relationship (DDPRQ-10), the Intent to Leave Scale (ILS) and the Occupational Disidentification Scale (ODS).

Results

The PIOSS includes 19 items divided into 3 dimensions: label identification, status loss, and career denial. The results of confirmatory factor analysis (CFA) reveal that the three-factor model fitted well (χ 2/df=2.574, RMSEA= 0.068, CFI= 0.931, IFI= 0.931, TLI= 0.919, PNFI= 0.762, PCFI= 0.795). The PIOSS total and each dimension scores were significantly negatively correlated with the CCS and the WWBS scores and remarkably positively associated with the DDPRQ-10, the ILS, and the ODS scores. Cronbach's α coefficients for the PIOSS total scale and dimensions ranged from 0.775 to 0.914, and split-half reliability coefficients ranged from 0.801 to 0.931. In addition, the PIOSS exhibited cross-gender invariance.

Conclusion

Having good reliability and validity, the PIOSS can serve as a valid tool for the assessment of physician internalized occupational stigma.
