From: Using path analysis to test theory of change: a quantitative process evaluation of the MapSan trial

Fig. 5

Linear probability path analysis of data from small compounds (≤ 20 members) of the MapSan trial. Path model for small compounds (≤ 20 members) subgroup assessing effects of a sanitation intervention on intermediary outcomes. Unstandardised path coefficients (bold type) represent the increase in absolute probability of the outcome as a result of a unit change in the exposure. Sections of the model corresponding to process evaluation domains and subdomains indicated by dashed lines. The model structure was less complex than that of the large compounds subgroup. Large direct effects on latrine maintenance (condition of slab/floor), privacy (working lock) and cleanliness were observed. Indirect effects on latrine cleanliness via cleaning behaviours were minimal. Intervention latrines were less likely to be accessible to all members of the compound. Abbreviations: HWF, handwashing facility; HWWS, handwashing with soap
