ABSTRACT
Social support plays a crucial role in maintaining marital satisfaction. By promoting gender equality in marriages (SDG 5), couples can foster a dynamic environment that enables both partners to thrive personally and professionally, enhancing overall marital well-being (SDG 3). This study employs a descriptive quantitative research design to investigate the construct validity and reliability of an instrument measuring spouse social support. The study's population consisted of married, working women with children, with a sample size of 300 participants selected through non-probability sampling techniques. Data were analysed using confirmatory factor analysis (CFA) to assess the instrument's ability to accurately measure the intended constructs of spouse social support. The CFA results validated several key indicators, including emotional, esteem, instrumental, informational, and network support, confirming the instrument's structural integrity. Additionally, internal consistency was evaluated using Cronbach's Alpha, which demonstrated a high level of reliability. The analysis revealed a strong alignment between the proposed model and the observed data, indicating that the instrument effectively captures the constructs it was designed to measure.
