Data Collection Tools and Procedures

Data were collected using a structured questionnaire through face-to-face interviews. The tool has socio-demographic characteristics, health-related factors, economic characteristics, and willingness to accept and pay for out-of-pocket payment sections. Six data collectors who were nurses with diploma-level qualifications and two supervisors who were public health officers were recruited. The questionnaires were first prepared in the English language, then translated to Amharic, then back to English to keep their consistency. The two-day training was given to data collectors and supervisors about the basic techniques and data collection tools. The collected data was checked by the principal investigator and the supervisors for its completeness. Double Bounded Dichotomous Choice Variant of the Contingent Valuation (CV) method was used to estimate the mothers’ willingness to pay for out-of-pocket payment of maternal and child health services. The participants were asked the maximum amount they were willing to pay for the service. The questionnaire was pretested on 29 mothers at Adet Hana kebele, one of the Kebeles found in the Yilmana Densa district with similar socio-demographic and economic status.
