Background: Family system has been found to affect the satisfaction level among the family members. The objective of our study was to determine the satisfaction level and its predictors among joint and nuclear family systems in District Abbottabad, Pakistan. Methods: We conducted a population-based cross-sectional study in all 52 Union Councils (UCs) of District Abbottabad, Khyber Pakhtunkhwa province, Pakistan from March 2015 to August 2015. Multistage cluster sampling technique was used to select 2063 participants from both nuclear and joint family houses. Proportionate sampling was done for selecting mohalla from each UCs, and then subsequently households from respective mohalla’ s. Simple random sampling was done for selecting the 18 years and above-aged participant for the study. A structured demographic questionnaire was used to collect information from study participants. Univariate and multivariate logistic regression analysis was done to find out the predictors of satisfaction level among joint and nuclear family systems using SPSS version 20 A p-value of <0. 05 was considered as significant. Results: Level of satisfaction was found to be higher among people living in the joint family system i. e., 87. 5 % v/s 81 % (<0. 001) compared to the nuclear family system. Multivariate regression analysis of nuclear family system showed that people having higher education level and higher socioeconomic status (SES) were more satisfied as compared to no education & low SES respectively. While, in the joint family system, only high SES was a significant predictor of satisfaction in the joint family system as compared to low SES. Conclusion: Our study reported a high level of satisfaction among joint and nuclear family systems in Pakistan. High education level and high SES were identified as important predictors of satisfaction among both systems.
