Psychological flexibility, self-compassion, subjective well-being, and substance misuse in college students: a serial mediation model.

ABSTRACT

Substance misuse is a pressing public health concern, especially among emerging adults, with implications for psychological health and overall well-being. This cross-sectional study investigates the mediating roles of self-compassion and subjective well-being in the relationship between psychological flexibility and substance misuse among Turkish college students. The study included 445 emerging adults enrolled at a state university in Türkiye. University participants were recruited via convenience sampling using snowball methods. Data were collected using self-report scales. The sample was 69% female (n = 307) and 31% male (n = 138) and ranged in age from 18 to 26 years (M = 20.85, SD = 1.35). In the study, Pearson product-moment correlation analysis was conducted to examine the relationships between the variables and then the serial mediation model was tested. The findings have revealed that psychological flexibility significantly predicts substance misuse, subjective well-being, and self-compassion. Additionally, the study identifies self-compassion as a mediator in the relationship between psychological flexibility and subjective well-being. While self-compassion contributes significantly to well-being, it does not explain the impact of psychological flexibility on substance misuse. Furthermore, subjective well-being also appears to be a mediator in the relationship between psychological flexibility and substance misuse, emphasizing its potential significance in reducing the likelihood of resorting substance misuse. Overall, the study contributes to understanding the pivotal role of self-compassion and psychological flexibility in fostering well-being and preventing substance misuse in the college setting.
