This dual role can create various demands that potentially affect their psychological well-being. In the context of Islamic boarding school life, spirituality and social support are believed to be factors that play a role in supporting their psychological wellbeing. This study aims to determine the relationship between spirituality and psychological wellbeing, the relationship between social support and psychological well-being, and the relationship between spirituality and social support in Islamic boarding school (santri) students. This study involved 225 respondents selected using a purposive sampling technique. Data were collected using the Spirituality Scale (38 items), the Social Support Scale (12 items), and the Psychological Well-Being Scale (16 items). Data analysis was performed using Spearman's rho correlation. The choice of nonparametric analysis was based on the results of examining the data distribution through the Shapiro–Wilk normality test, histogram, Q–Q plot, boxplot, and skewness and kurtosis values, which indicated the presence of distribution deviations and extreme values, especially in the social support variable. Therefore, Spearman's correlation was considered more appropriate for use. The results of the study showed that spirituality had a significant positive relationship with psychological well-being (rs = 0.266; p < 0.001) with a small to moderate strength of relationship. Social support also had a significant positive relationship with psychological wellbeing (rs = 0.184; p = 0.006) with a small strength of relationship. In addition, spirituality had a significant positive relationship with social support in Islamic boarding school students. Thus, the higher the spirituality, the higher the psychological well-being, and the higher the social support, the higher the psychological well-being in Islamic boarding school students.302 Interaksi Sosial, Hubungan Antarpersonal2026-06-15UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU SOSIAL DAN HUMANIORAThesis
