Exploring change over time in community mobilization domains: results from a maternity waiting home intervention in rural Zambia.

backgroundCommunity mobilization (CM) is recommended as a best practice intervention for low resource settings to reduce maternal mortality. Measurement of process outcomes are lacking and little is known about how CM impacts individuals or how community members perceive its function. Given the complex and recursive nature of CM interventions, research that describes the CM process at multiple levels is needed. This study examines change in CM domains at baseline and endline in rural Zambia.

methodsThis secondary analysis uses data from a large maternity waiting homes intervention in rural Zambia that employed CM over 3 years as part of a package of interventions. A 19-item CM survey was collected from three groups (women with babies < 1, health workers, community members; n = 1202) with focus groups (n = 76) at two timepoints from ten intervention and ten comparison sites. Factor analysis refined factors used to assess temporal change through multivariable regression. Independent covariates included time (baseline vs endline), intervention vs comparison site, group (women with babies, healthworkers, community members), and demographic variables. Interaction effects were checked for time and group for each factor.

resultsFinal analyses included 1202 individuals from two districts in Zambia. Factor analysis maintained domains of governance, collective efficacy, self-efficacy, and power in relationships. CM domains of self-efficacy, power in relationships, and governance showed significant change over time in multivariable models. All increases in the self-efficacy factor were isolated within intervention communities (b = 0.34, p < 0.001) at endline. Between groups comparison showed the women with babies groups consistently had lower factor scores than the healthworkers or community member groups.

conclusionsCommunity mobilization interventions increase participation in communities to address health as a human right as called for in the 1978 Alma Ata Declaration. Grounded in empowerment, CM addresses socially prescribed power imbalances and health equity through a capacity building approach. These data reflect CM interventions function and have impact in different ways for different groups within the same community. Engaging directly with marginalized groups, using the community action cycle, and simultaneous quality improvement at the facility level may increase benefit for all groups, yet requires further testing in rural Zambia.
