PIP: This report analyzes data from a survey of 106 Barangay (village) Service Point Officers (BSPOs) associated with the City Population Office and 106 Barangay Health Workers (BHWs) associated with the City Health Office to compare the family planning (FP) service delivery performance of these voluntary workers in Iloilo City in the Philippines and to quantify the effects of the factors which influence their performance. Both the BSPOs and the BHWs assist in the delivery of health and FP services at the grassroots level. The survey data were supplemented with interviews with key informants, focus group discussions with married couples of reproductive age, clinic records, and observations of the BSPOs and BHWs at work. The analysis compared the sociodemographic characteristics of the two groups; the recruitment procedures followed (if any); FP training; actual FP-related work; involvement in community organizing; incentives received; supervision of the volunteers; attitude towards their work; FP knowledge, attitude, and practice; time allocated to FP activities; number of clients served; and number of clients counseled. Correlation analysis of factors influencing volunteer performance indicated that FP training had the largest positive influence on FP activities. The output of the workers was also positively affected by the amount of time spend in FP activities and by their involvement in community organizing. The commitment of the workers had a significant impact on the number of clients they resupplied with contraceptives. Variation in the FP performances of the two groups was caused by the fact that delivery of FP services is a major role of the BSPOs and only one of many responsibilities of the BHWs. These findings reinforce the planned restructuring of Iloilo City's FP program which would once again designate the Population Office as the lead agency. Increasing the knowledge of these volunteers about the side effects and contraindications of various methods should have a positive effect on continuation rates. Recruitment of volunteers should be based on the individual's level of interest and commitment.
