Loneliness Mediates the Link Between Indirect Self-Destructive Behavior and Life Satisfaction in Women from Dysfunctional Family Backgrounds

<b>Background:</b> Among individuals who perceive their families of origin as dysfunctional, both indirect self-destructive behaviors and loneliness seem to be important correlates of life satisfaction. However, a review of the existing literature reveals a notable absence of studies that examine these variables within a single analytical framework. <b>Objectives</b>: Given the limited number of studies examining the relationship between indirect self-destructive behavior, loneliness, and life satisfaction among women from dysfunctional family backgrounds, this study aimed to: (1) examine the association between indirect self-destructive behavior and life satisfaction among women experiencing different types of family dysfunction, and (2) determine whether loneliness mediates this relationship. <b>Methods</b>: The research was conducted among 207 women aged 18 to 63 (<i>M</i> = 30.78 years; <i>SD</i> = 9.945) who were raised in dysfunctional families. The Indirect Self-Destructiveness Scale [ISDS-25], the Satisfaction with Life Scale [SWLS], and the De Jong Gierveld Loneliness Scale [DJGLS] were used. <b>Results</b>: Statistically significant correlations were obtained between all pairs of variables: (1) loneliness and life satisfaction (<i>r</i> = -0.50 ***); (2) life satisfaction and indirect self-destructive behavior (<i>r</i> = -0.31 ***); (3) loneliness and indirect self-destructive behavior (<i>r</i> = 0.20 **). Moreover, mediation analyses showed two outcomes. First, loneliness acted as a mediator in the relationship between indirect self-destructive behavior and life satisfaction. Second, indirect self-destructive behavior had a mediation effect on the relationship between loneliness and life satisfaction. <b>Conclusions</b>: The conducted study and the obtained results fill a significant gap in the knowledge about indirect self-destructive behaviors, loneliness, and their relationship with the dysfunction of the family of origin. Thus, they constitute a new resource of expertise for interdisciplinary teams working with adults.
