From: Impact of reliable light and electricity on job satisfaction among maternity health workers in Uganda: A cluster randomized trial

  1. Linear models that use data from both baseline and follow-up surveys and include facility fixed effects. Results show point estimate and 95% confidence interval. Standard errors are clustered at facility level. Satisfied with light and electricity is equal to 1 if health worker strongly agrees or agrees with both (1) I am satisfied with the availability and brightness of light in this facility and (2) I am satisfied with the availability of electricity in this facility. Impact of lack of overhead light index is an index of 14 items measuring health workers’ assessment of impact of lack of overhead light on their ability to conduct job tasks, including how often health worker: conducted deliveries without overhead light; had to hold torch in hand/mouth to see patient; experienced lack of light that affected normal care provided; delayed care; feared to move around facility; was affected in ability to suture, find/use equipment, conduct examinations of mother, provide emergency care, provide newborn care, monitor fetal heartrate, administer medication, clean up after delivery, manage infection control. This is reversely coded so that higher score indicates more frequent negative impact. Job satisfaction index is the mean score of four statements on a 1–5 scale: (1) These days, I feel motivated to work as hard as I can. (2) Overall, I am satisfied with my job. (3) Overall, the morale level at my department is good (4) I plan on staying at this position for the next year. *p < 0.05, **p < 0.01, ***p < 0.001
