긍정심리자본이 삶의 만족도에 미치는 영향 : 사회적 지지의 매개효과 중심으로

다국어 초록 (Multilingual Abstract)

The purpose of this study was to examine the effects of positive psychological capital on life satisfaction among university students and to investigate the mediating role of social support in this relationship. In addition, this study explored whether the levels of positive psychological capital, social support, and life satisfaction differ according to demographic characteristics such as gender and academic year, in order to provide basic data for promoting subjective well-being in college students.
The participants were 186 undergraduate students enrolled in universities located in the Gyeongbuk–Daegu region of Korea. Data were collected through an online survey using Naver Form. Positive psychological capital, social support, and life satisfaction were measured using self-report questionnaires adapted from the Psychological Capital Questionnaire (PCQ), the Social Provisions Scale (SPS), and the Satisfaction With Life Scale (SWLS), all of which have been validated in previous research. The collected data were analyzed using SPSS, and descriptive statistics, reliability analysis, t-tests, one-way ANOVA, correlation analysis, regression analysis, and mediation analysis based on Baron and Kenny’s procedure and the Sobel test were conducted.
The results of this study can be summarized as follows. First, university students’ positive psychological capital, perceived social support, and life satisfaction were found to be above the moderate level, and there were significant positive correlations among the three variables. Students with higher positive psychological capital perceived higher levels of social support and reported higher life satisfaction. Second, there were no significant differences in positive psychological capital, social support, or life satisfaction according to gender, whereas partial differences in life satisfaction were observed across academic years. Third, positive psychological capital had a significant positive effect on life satisfaction, and social support also positively predicted life satisfaction. Finally, social support showed a partial mediating effect in the relationship between positive psychological capital and life satisfaction, indicating that internal psychological resources and interpersonal resources jointly contribute to the enhancement of students’ life satisfaction.
Based on these findings, the study suggests the importance of developing counseling and educational programs in university settings that strengthen students’ positive psychological capital—such as self-efficacy, hope, resilience, and optimism—while simultaneously fostering supportive interpersonal environments that enhance emotional and instrumental social support.
