Development of a HIV Prevention Program to Promote Condom Use Among Iranian Female Sex Workers: Application of An Intervention Mapping Approach

We used an Intervention Mapping Approach (IMA) to derive multi-level HIV prevention strategies aiming to develop an HIV prevention intervention program among female sex workers (FSWs). We also aimed at pilot testing the effects of the IMA-based “HIV Prevention and Awareness Program (HIV-PAP)” on safe sex behaviors and its determinants among FSWs in Tabriz, Iran. To develop HIV-PAP, we conducted the six-step process of IMA. At Step 1, in a cross-sectional study, 140 FSWs were face-to-face interviewed. At Step 2, the program matrix was provided based on the importance and variability for identifying priority factors. At Steps 3 and 4, the methods and strategies for behavioral change were selected, and the HIV-PAP program components and materials were developed. At Steps 5 and 6, evaluation (as a pilot testing with Static-Group Comparison design) was conducted applying a pre-experimental study, in which 30 FSWs were assigned to intervention ( n = 15) and control ( n = 15) groups. The intervention group participated in a two-month long program, and one month later, the initial questionnaires were completed by both groups. The respondents (M age: 33.4 years, SD: 9.7) acquired low score (less than 50%) in negotiating for condom use (49.8%) only, and moderate scores (50–65%) in perceived social support (61.6%) and knowledge (60.5%). Adjusted for other variables, the factors ( R 2 = 32.0%) associated with safe sex behaviors among FSWs were predisposing factors [self-efficacy ( β = 0.331), perceived norms (β = 0.945), and perceived barriers (β = 0.258)], condom use negotiation (β = 1.386), and environmental factors (β = 0.333). Our IM-based framework had an adequate fit index (χ 2 = 130.8, CFI = 0.78). Looking for inter-group comparison after intervention, we found significant mean difference (MD) for knowledge (MD: 2.18; 95% Confidence Interval (CI) − .38 to 4.74, p
