Data collection procedures

Data for the quantitative section were collected using a structured Afan Oromo questionnaire. Four diploma nurse data collectors with previous experience in data collection were recruited. One supervisor with the first degree in health was assigned. Two days of training was given to the data collectors and supervisor on how to collect the data and other related procedures by the investigator. A standard questionnaire that addresses the objectives of the study under investigation was adapted through searching the relevant literatures.^14–21 The questionnaire was initially prepared in English and then translated into Afan Oromo. The Afan Oromo version was again translated back to English to check for consistency of the meaning.

To supplement the quantitative data, qualitative data was collected through face-to- face in-depth interview. Data were collected at the workplace by the primary researcher, A.G.G. who was male, a health specialist, and had 2 years of research experience. The participants were selected purposively among daily laborers and permanent health staff until the required information was saturated. Semi-structured open-ended discussion guides were used to facilitate the discussion and all in-depth interviews were monitored by the principal investigator. Every discussion was tape-recorded, transcribed, and translated from Afan Oromo language to English, and finally summarized for writing the article.
