The relationship between impulsivity and attention-deficit/hyperactivity symptoms in female patients with borderline personality disorder

OBJECTIVES: In this present study, we aimed to examine the relationship between impulsivity and attention-deficit/hyperactivity symptoms in female patients with borderline personality disorder (BPD) and compare these symptoms with a healthy group.

METHODS: The sample of this study was composed of randomly selected 90 female patients diagnosed with BPD according to Diagnostic and Statistical Manual of Mental Disorders–Fifth Edition (DSM-5) criteria and not receiving any medical treatment during the past six months since presented to the Bagcilar Training and Research Hospital and randomly selected 90 healthy controls who were free of any psychiatric disorders. Semi-structured sociodemographic data form, Adult ADHD Self-Report Scale (ASRS-v1.1), and Barratt Impulsiveness Scale (BIS-11) were administered.

RESULTS: Total BIS scores were statistically significantly correlated with total ASRS (r = .557, p < .001) and its two subscales: Inattention (r = .593, p < .001) and Hyperactivity/Impulsivity (r = .399, p < .001). The results of Chi-square test revealed a statistically significant difference in terms of being diagnosed with attention-deficit/hyperactivity disorder (ADHD) or not between patient and healthy group (χ2 = 46.667, df = 1, p = .000). Furthermore, there was a statistically significant difference between the patients and the healthy controls in terms of total BIS-11 [t(178) = 10.444, p = .000] and total ASRS [t(178) = 9.697, p = .000]. The results of hierarchical multiple regression revealed that Motor subscale scores were significantly predictive of ASRS scores [R2 = .337, F(6,82) = 5.960, p = .00].

CONCLUSIONS: In this present study, patients with BPD had higher rates of comorbid ADHD and impulsivity scores than healthy controls. ASRS scores and BIS scores were positively correlated, and motor subscale scores were significantly predictive of ASRS scores.
