Background: Studies on the solitude capacity of university students have been extremely limited and failed to clearly illustrate the correlation of solitude capacity with internal psychological variables and the favorability of interpersonal relationships. The aim of this study was to explore the correlation of college students' solitude capacity with scores for self-esteem, self-efficacy, and interpersonal relationships. Method: A cross-sectional study was adopted for this study. Data were collected from a university in southern Taiwan using a structured questionnaire, the content of which included demographic data and scores from the Rosenberg Self-Esteem Scale (RSE), the General Self-Efficacy Scale (GSE), the Interpersonal Relationship Scale (IRS), and the Solitude Capacity Scale (SCS). Results: The final sample comprised 562 participants (mean age = 17.51 ± 1.27 years). Adjustment of the demographic variables yielded a significantly positive correlation in the total RSE and SCS (p < 0.01) scores and that in the total GSE and SCS (p < 0.01) scores. Moreover, the relationship with family (IRS subscale) and total SCS score (p < 0.05) exhibited a significant positive correlation. Conclusion: The findings of this study reveal that solitude capacity is significantly correlated with self-esteem, self-efficacy, and the favorability of family relationships.
