Psychometric properties of the Level of Personality Functioning Scale- Brief Form 2.0 (LPFS-BF 2.0) in women with attention-deficit/hyperactivity disorder

Women with attention-deficit/hyperactivity disorder (ADHD) are also often diagnosed with personality disorders, yet research on reliable and valid assessments of personality pathology in this population has been limited. In this study, the psychometric properties of the Level of Personality Functioning Scale- Brief Form – 2.0 (LPFS-BF 2.0) were examined in a sample of 171 adult women with ADHD. A two-factor structure was identified, with one factor, LPF-self, comprised of six items, reflecting impairment in self functioning; the second factor, LPF-interpersonal, comprised of six items, reflecting impairment in interpersonal functioning. LPFS-BF 2.0 factors contributed unique variance to functional impairment beyond the effects of co-occurring depression, anxiety, and ADHD. These findings suggest the LPFS-BF 2.0 may be important to include in clinical care for women with ADHD, to identify those women with ADHD who may require adjunctive intervention for personality pathology.
