2.3. Study Participants and Sampling

A purposive sampling technique was used to recruit 60 HEWs from the three zones (Table 1). The HEWs were recruited based on certain criteria or considerations (i.e., inherently criterion/judgmental sampling technique) such as the number of the population they serve, level of education, work experience, diversity in distance from health centers, and performance.
