This study aimed to assess the level of job-related affective well-being among middle school teachers in Riyadh by administering the Job-Related Affective Well-Being Scale (JAWS) developed by Van Katwyk et al.,(2000), after translating it and verifying its psychometric properties. The scale was administered to a sample of( 415) teachers. The findings indicated that, overall, teachers demonstrated a moderate level of job-related affective well-being. The High Positive Low Arousal (HPLA) dimension ranked first, followed by High Positive High Arousal (HPHA), Low Positive Low Arousal (LPLA), and finally Low Positive High Arousal (LPHA). These results suggest that teachers experience a satisfactory degree of affective well-being; however, it does not reach a high motivational level. Furthermore, the study found no statistically significant differences in affective well-being based on gender or years of service, whereas age-related differences were observed, favoring teachers aged 36–45 years and those over 45 years.\".
