• This study evaluates the validity and factorial structure of the affective job satisfaction scale (BIASJ) among 234 workers from private institutions of social solidarity (IPSS) in Portugal. Emotional job satisfaction, a key marker of psychological well-being, is associated with positive outcomes for employees and organizations. The sample was mainly female, with an average age of 39.15 years (SD = 8.22). The BIASJ and Maslach burnout inventory (MBI) measured job satisfaction and burnout. The BIASJ demonstrated high internal consistency (Cronbach’s alpha = 0.87, McDonald’s omega = 0.88) and a unidimensional structure. Significant negative correlations with emotional exhaustion and depersonalization supported its criterion validity. The results confirm the BIASJ as a reliable instrument for assessing job satisfaction in IPSS settings in Portugal. Future research should incorporate more diverse, gender-balanced samples and utilize probability sampling to improve generalizability.
