<![CDATA[Achievement motivation is an important psychological factor underlying students’ academic engagement and success. This study examined whether spiritual intelligence, self-regulation in piety, and parental attitudes toward children significantly predict achievement motivation among Indonesian university students. A quantitative cross-sectional design was employed with 280 undergraduate students from West Sumatra, DKI Jakarta, and the Special Region of Yogyakarta, selected through proportional stratified sampling. Data were collected using Likert-type instruments with good internal consistency (Cronbach’s α = .799–.893) and analyzed using multiple linear regression. The results indicated that the three predictors jointly explained 92.2% of the variance in achievement motivation (F(3, 276) = 686.279, p < .001). Spiritual intelligence (β = .203), self-regulation in piety (β = .663), and parental attitudes toward children (β = .143) were positive and significant predictors (p < .001). Self-regulation in piety demonstrated the strongest predictive association. These findings suggest that achievement motivation is associated with the interplay of spiritual intelligence, value-based self-regulation, and supportive parental attitudes within the Indonesian cultural context. The findings extend achievement motivation perspectives by highlighting culturally situated internal and social-contextual resources. However, the cross-sectional self-report design limits causal interpretation, and the high explained variance should be interpreted cautiously due to potential shared variance and common-method bias.]]>
