Dissertation (MA Development Studies)The study analyzes the contribution of social accountability to public social service delivery: the case of the health sector in Chamwino District. The rationale of the study was drawn in the puzzle between the realization of human rights and capabilities. Although accessibility and satisfaction of needs depend on a number of variables, citizens’ capabilities to demand and monitor accountability is central to all. To address this, the study embarked on three objectives: to examine the role of social accountability in the health sector at Chamwino district, to assess the level of the health service users’ participation on the social accountability in public health service delivery and to explore the factors influencing social accountability to health service users. A cross-sectional design was employed with 115 respondents taken as a sample using different tools such as questionnaires, interview, and observation guide. The data were analyzed using content analysis and descriptive statistical analysis through inferential statistics of cross-tabulation, regression and Chi-Square. The chi-square analysis on different tests of the findings in the study has revealed that there is a significant relationship between social accountability and public health service delivery, and thus making it the most crucial determinant of health sector performance at primary health facility levels. The theoretical and practicability values of the study make its results authentic to scholars, government, private sectors and citizens in understanding the existing relationship between social accountability and public social service delivery. This understanding can promote citizens’ participation, accountability and transparency.
