Development and Psychometric Evaluation of HealthProtective Sexual Communication Measures for Young Women Aged 21-35Years Attending Selected MCH Clinics in Gaborone, Botswana for HIVPrevention 公开

Abstract

Background Botswana, with 1.7 million people, ranks second highest in HIV sero-prevalence worldwide, heterosexually transmitted and affecting more women than men. Health protective sexual communication (HPSC) between sexual partners can contribute to HIV prevention, but women face difficulties with HPSC due to cultural and gender issues. Valid and reliable measures are needed to explore young women's perceptions and beliefs about HPSC for HIV prevention interventions.

Purpose The purpose this dissertation research was to develop and evaluate psychometric measures of HPSC measures to guide culturally sensitive HIV prevention interventions for young women in Gaborone, Botswana. The study was guided by the Theory of Planned Behavior (TPB).

Methods This cross-sectional multi stage multi-method dissertation study was conducted in Gaborone, Botswana among young women attending selected MCH clinics, selected through purposive sampling. Literature review of existing measures and a qualitative elicitation pilot directed apriori content validity. Eleven measures were developed, translated and evaluated for content validity. A quantitative pilot among was conducted among 10 women for administrative feasibility. A larger quantitative study among 280 young women was conducted in the 13 city clinics for reliability, validity and hypothesis testing. All women recruited met the selection criteria, consented and responded to all questions.

Results Twelve major themes and 20 sub-themes were elicited and used as items for 11 HPSC measures. Two measures were unreliable, one had spuriously low reliability due to its brevity. Eight measures were reliable, with Cronbach's alphas between 0.70 and 0.95. Underlying factors were extracted for these using principal components analysis. Some significant relationships were identified between measures.

Discussion of Findings The TPB successfully guided the instrument development process, yielded reliable and valid measures, which had some significant relationships. Theresults highlighted the importance of HPSC, the significant influece of the male sexual partners and other relatives, and the need to integrate HPSC at all levels of HIV/AIDS prevention and control, and research, focusing on the effectiveness of HPSC.
