The career well-being approach was based on the concept of general well-being which included affective and cognitive components. The respondents were mothers working full-time in the formal sector and had fulfilled the requirement of several pre- determined criteria. The collected research data was analyzed with the confirmatory factor analysis in order to obtain instrument reliability and validity. Based on the analysis, results were obtained that the WBWS model adaptated had fulfilled the goodness-of-fit criteria, meaning that there was compatibility between the developed model and the empirical data. Furthermore, this research was hoped to provide contribution in the measurement and development of research of career well-being on working mothers.

In 2014, the number of women in the productive age group was 85 million, or around 65 percents of the total number of citizens (BPS, 2014). This massive number showed the human resource potential for development, and if women in the productive age were not able to work productively, it would result in economic burden for Indonesia.
