Background: Parental invalidation is thought to contribute to severity of borderline personality disorder (BPD) severity. Certain family functioning environments may foster more invalidation than others. The current study serves to examine how dysfunctional family functioning may allow for BPD symptoms development through the fostering of invalidating environments. Method: 60 female adolescents completed the Borderline Symptoms List (BSL-23), the Family Adaptability and Cohesiveness Evaluation Scale (FACES-V), and the Invalidated Childhood Environment Scale adapted for adolescents (ICES-A) at baseline of a 20-week dialectical-behavioural therapy. Results: Only maternal invalidation was positively correlated with severity of BPD symptoms. Furthermore, maternal invalidation mediated the relationship between disengaged family functioning and adolescent BPD symptoms. Limitations: The ICES-A is currently undergoing validation, therefore results should be interpreted cautiously. Also, the clinical sample used in the study presented with a restricted upper-bound range of symptoms, thus limiting generalizability. Conclusions: These findings highlight the need to work upon the family environment for the treatment of BPD symptoms, especially in adolescence before symptoms become consolidated.
