Validation of the Supportive Community Index: survey research on Girls’ Vulnerability to HIV/AIDs from Botswana, Malawi, and Mozambique Carol Underwood, Ph.D. & Hilary Schwandt, Ph.D. Johns Hopkins University
Go Girls! Initiative: Goal & Social-ecological conceptual framework GOAL: To reduce HIV prevalence among adolescent girls aged 10-17 in Botswana, Malawi & Mozambique
Social ecology & combined prevention • SE approach posits interrelated roles of intrapersonal, interpersonal, institutional, community, and structural levels • SE interventions encompass the three elements of combined prevention – biomedical (individual level), behavioral (individual & social normative), and structural interventions
Model 1:Individual & community level Life Skills Out-of-school Adult-Child Communication Community Mobilization Reality Radio
Model 2:Multi-level: individual, community & structural approach School Personnel Training Economic Strengthening
GGI’s whole-community approach Communities: Community mobilization Radio program Safe schools: Teacher training Girls: School-based and community-based life skills Extended families: Adult-child communication Economic strengthening
Formative research • Literature review of “vulnerable girls” • Qualitative study to examine community perspectives’ of “vulnerable girls” Results informed and helped to refine 3 indices in advance of the baseline survey

Supportive Community Index • What is it? • A community/structural level measurement tool • How can it be utilized? • Measure the level, and change in, community/structural support in a community – emphasizing vulnerable girls’ support • Why is it important? • Communities/structures have a large impact on individual behaviors yet they are rarely addressed or evaluated • Measurement allows for evaluation of structural interventions
Why focus on structural factors? • Research shows that structural factors – access to educational, employment, & financial opportunties as well as policies that affect the distribution of resources – are key to HIV reduction • Yet, structural interventions lag behind biomedical and individual-level behavioral interventions • Nonetheless, community members prioritize structural interventions • Practitioners argue that structural effects are difficult to measure
Baseline Supportive Community Index (SCI) From three populations: Key Informants Adults Adolescents
SCI Domains – Key Informants • Access to health services • Concerns about alcohol abuse • Regulation of alcohol • Community cohesion • Community groups • Community safety • Economic opportunities • Community support • Gender and community • School safety • Sexual abuse concerns • Regulation of sexual abuse
Community Action (Outcome) Domains – Key Informants • Alcohol action “In the past 12 months, has the community taken any action to address the issue of outlets selling alcohol to people younger than 18 years?” • Sexual abuse action • Vulnerable girls support • Community health “In the last year, has the impact of HIV/AIDS on the community improved, worsened, or stayed the same?”
Correlation of the SCI and Community Action – Key Informants • Botswana (n=21) • Range: 67-146 • Correlation = 0.79 • Malawi (n=40) • Range: 60-135 • Correlation = 0.73 • Mozambique (n=82) • Range: 43-138 • Correlation = 0.55
Baseline Supportive Community Index (SCI) From three populations: Key Informants Adults Adolescents
SCI Domains - Adults • Alcohol regulation “How likely do you think it is that an adolescent younger than 18 years of age will obtain alcohol in this community if he or she tries?” • Community cohesion “When conflicts or disagreements arise between community members, they are always resolved quickly.” • Community safety • Economic opportunities • School safety • Sexual abuse regulations
Community Action Outcome Domains - Adults • Community support Example: “In the last 12 months, have people in your community worked together to address HIV/AIDS?” • Vulnerable girls support Example: “In the last 12 months, has any action been taken in the community to improve the well-being of adolescent girls?”
SCI and Outcome - Adults • Linear Regression • Main predictor: SCI • age, marital status, parity, and residence • Botswana (n=530) • β = 0.22; 95% CI (0.17, 0.27)* • Malawi (n=615) • β=0.17; 95% CI (0.14, 0.21)* • Mozambique (n=529) • β=0.14; 95% CI (0.095, 0.18)* *p = 0.000
BaselineSupportive Community Index (SCI) From three populations: Key Informants Adults Adolescents
SCI Domains - Adolescents • Poverty • Food security • Home security • Alcohol access & regulation • Community cohesion • Community safety • Economic opportunities • School safety • Sexual abuse regulations
Outcome Variable - Adolescents Sexual experience “Have you ever had sexual intercourse?”
SCI and Sex - Adolescents • Logistic Regression • Main predictor: SCI • Age, current schooling status, orphan status, & residence • Botswana (n=560) • OR = 0.81; p = 0.000 • Malawi (n=752) • OR = 0.93; p = 0.041 • Mozambique (n=427) • OR = 0.91; p = 0.017
Measuring Structural Change • Measurement of the SCI at 2 time points • Baseline • Endline • Comparing change • Analyze the % change in community aggregate scores • Hypothesis • + % SCI change • SCI Model II > SCI Model I
Conclusions • SCI is strongly associated with hypothesized outcomes • In 3 countries • In 3 populations • Cross-country validation of the SCI
Implications • Most behavior change research and programs focus on the individual – ignoring the structures outside the individual influence • GGI (research & program) has been designed with a community and structural level focus • GGI is implementing a structural level intervention in three countries • As well as measuring the structural change through the SCI • Future researchers and programs can use these tools to design and test structural level interventions
