Cultural Consensus Modeling to Understand South African Adolescent Girls' Attitudes, Awareness, and Uptake of Dual Protection Strategies

Abstract

Purpose: This study used cultural consensus modeling to elucidate culturally relevant factors associated with dual protection use (strategies to prevent both pregnancy and sexually transmitted infection [STI]/HIV) among South African adolescent girls aged 14-17 years.

Methods: In Phase 1, participants (N = 50) completed a free-listing survey assessing pregnancy and STI/HIV methods used by peers. In Phase 2, participants (N = 100) completed a rating survey to examine perceived peer acceptability of Phase 1 pregnancy and STI/HIV prevention methods. In Phase 3, qualitative individual interviews (N = 25) gathered in-depth information regarding the cultural acceptability of pregnancy and STI/HIV prevention strategies. In Phase 4, participants (N = 300) completed the Phase 2 rating survey for individual beliefs regarding the acceptability of pregnancy and STI/HIV prevention methods.

Results: In Phase 1, 41 pregnancy and 29 STI/HIV prevention strategies, along with 16 factors influencing pregnancy prevention method acceptability were endorsed; male condoms were the most commonly endorsed pregnancy and STI/HIV prevention method. In Phase 2, using cultural consensus analysis, participants were consistent in the perceived acceptability of pregnancy and STI/HIV prevention methods (73.4% variance accounted for in single cultural model). In Phase 3, qualitative findings provided in-depth information regarding factors influencing commonly used pregnancy (e.g., injectable contraception) and STI/HIV (e.g., condoms) prevention methods. In Phase 4, a single cultural model was identified (56.3% variance accounted for), with similar acceptability ratings as Phase 2.

Conclusions: A singular cultural model of pregnancy and STI/HIV prevention method acceptability was observed, with little awareness of dual protection. The findings highlight cultural factors for future culturally tailored dual protection interventions for South African adolescent girls.
