The Short Version of the Borderline Symptom List (BSL-23): Development and Initial Data on Psychometric Properties

Background: The full version of the Borderline Symptom List (BSL; for clarification now labeled BSL-95) is a self-rating instrument for specific assessment of borderline-typical symptomatology. The BSL-95 items are based on criteria of the DSM-IV, the revised version of the Diagnostic Interview for Borderline Personality Disorder, and the opinions of both clinical experts and borderline patients. The BSL-95 includes 95 items. In order to reduce patient burden and assessment time, a short version with 23 items (BSL-23) was developed. Methods: The development of the BSL-23 was based on a sample of 379 borderline patients, considering the items from the BSL-95 that had the highest levels of sensitivity to change and the highest ability to discriminate borderline patients from other patient groups. In a second step, the psychometric properties of the BSL-23 were investigated and compared with the psychometric properties of the BSL-95 in 5 different samples, including a total of 659 borderline patients. Results: In all of the samples, a high correlation of the sum score was found between the BSL-23 and the BSL-95 (range: 0.958–0.963). The internal consistency was high for both versions (BSL-23/Cronbach’s α: 0.935–0.969; BSL-95/Cronbach’s α: 0.977–0.978). Both BSL-23 and BSL-95 clearly discriminated borderline personality disorder patients from patients with an axis I diagnosis (mean effect sizes were 1.13 and 0.96 for the BSL-23 and BSL-95, respectively). In addition, comparisons before and after 3 months of dialectical behavior therapy revealed a numerically larger effect size for the BSL-23 (d = 0.47) compared to the BSL-95 (d = 0.38). Conclusion: The results indicate that the BSL-23 is an efficient and convenient self-rating instrument that displays good psychometric properties comparable to those of the BSL-95. The BSL-23 also demonstrated sensitivity to the effects of therapy.

Psychiatric comorbidity and functional impairment in a clinically referred sample of adults with attention-deficit/hyperactivity disorder (ADHD)

ObjectiveThis exploratory study aims to compare lifetime psychiatric axis-I-comorbidity and psychosocial functioning in a clinically referred sample of adult patients with attention-deficit/hyperactivity disorder (ADHD) with a population-based healthy control group and to examine whether patients with ADHD and lifetime comorbid diagnoses differ from patients with pure ADHD in their functional impairment.MethodSeventy adult patients with ADHD according to DSM-IV criteria and a gender- as well as age-matched population based control group underwent diagnostic evaluations with clinical interviews for ADHD, DSM-IV disorders and demographic information.ResultsThe prevalence of psychiatric lifetime comorbidity was 77.1% in patients with ADHD and thus exceeded the rate in the control group, which was 45.7%. Significantly more patients suffered from depressive episodes, substance related disorders and eating disorders. Compared to the control group adults with ADHD were significantly impaired in a variety of psychosocial functions (education, occupational training). Patients with ADHD and lifetime diagnosis of comorbid psychiatric disorders differed from patients with pure ADHD in their psychosocial functioning only in the percentage of unemployed individuals, which was higher in patients with psychiatric comorbidity.ConclusionAdults with ADHD suffer significantly more often from other psychiatric disorders than individuals of the population-based control group and are impaired in several areas of psychosocial functioning. Poor psychosocial outcome is primarily related to ADHD and not to additional psychiatric disorders. Due to the limited number of assessed patients these results need to be confirmed by studies with larger sample size.

Attention Deficit/Hyperactivity Disorder as a Potentially Aggravating Factor in Borderline Personality Disorder

BACKGROUND Clinical experience suggests that people with borderline personality disorder often meet criteria for attention-deficit hyperactivity disorder (ADHD). However, empirical data are sparse. AIMS To establish the prevalence of childhood and adult ADHD in a group of women with borderline personality disorder and to investigate the psychopathology and childhood experiences of those with and without ADHD. METHOD We assessed women seeking treatment for borderline personality disorder (n=118) for childhood and adult ADHD, co-occurring Axis I and Axis II disorders, severity of borderline symptomatology and traumatic childhood experiences. RESULTS Childhood (41.5%) and adult (16.1%) ADHD prevalence was high. Childhood ADHD was associated with emotional abuse in childhood and greater severity of adult borderline symptoms. Adult ADHD was associated with greater risk for co-occurring Axis I and II disorders. CONCLUSIONS Adults with severe borderline personality disorder frequently show a history of childhood ADHD symptomatology. Persisting ADHD correlates with frequency of co-occurring Axis I and II disorders. Severity of borderline symptomatology in adulthood is associated with emotional abuse in childhood. Further studies are needed to differentiate any potential causal relationship between ADHD and borderline personality disorder.

Structured group psychotherapy in adults with attention deficit hyperactivity disorder: results of an open multicentre study.

Attention deficit hyperactivity disorder (ADHD) is a serious mental disorder that often persists in adulthood. In a pilot study, a structured skills training group program for adult ADHD led to significant symptomatic improvements. The present study evaluated the programs effectiveness, feasibility, and patient acceptability in a multicenter setting. Seventy-two adult ADHD patients were assigned to 13 two-hour weekly sessions at 4 different therapy sites. The therapy was well tolerated and led to significant improvements of ADHD, depressive symptoms, and personal health status (p < 0.001). The factors treatment site and medication did not contribute to the overall improvement. Patients regarded the program topics “behavioral analyses,” “mindfulness,” and “emotion regulation” as the most helpful. In this multicenter study, the therapy program showed therapist-independent effects and seemed to be disorder-specific. This warrants the effort of organizing further controlled studies.

Differential nociceptive deficits in patients with borderline personality disorder and self-injurious behavior: laser-evoked potentials, spatial discrimination of noxious stimuli, and pain ratings

&NA; Approximately 70–80% of women meeting criteria for borderline personality disorder (BPD) report attenuated pain perception or analgesia during non‐suicidal, intentional self‐mutilation. The aim of this study was to use laser‐evoked potentials (LEPs) and psychophysical methods to differentiate the factors that may underlie this analgesic state. Ten unmedicated female patients with BPD (according to DSM‐IV) and 14 healthy female control subjects were investigated using brief radiant heat pulses generated by a thulium laser and five‐channel LEP recording. Heat pulses were applied as part of a spatial discrimination task (two levels of difficulty) and during a mental arithmetic task. BPD patients had significantly higher heat pain thresholds (23%) and lower pain ratings (67%) than control subjects. Nevertheless, LEP amplitudes were either normal (N1, P2, P3) or moderately enhanced in BPD patients (N2). LEP latencies and task performance did not differ between patients and control subjects. The P3 amplitudes, the vertex potential (N2–P2), and the N1, which is generated near the secondary somatosensory cortex, were significantly reduced during distraction by mental arithmetic in both groups. In addition, P3 amplitudes reflected task difficulty. This study confirms previous findings of attenuated pain perception in BPD. Normal nociceptive discrimination task performance, normal LEPs, and normal P3 potentials indicate that this attenuation is neither related to a general impairment of the sensory‐discriminative component of pain, nor to hyperactive descending inhibition, nor to attention deficits. These findings suggest that hypoalgesia in BPD may primarily be due to altered intracortical processing similar to certain meditative states.

Elevated pain thresholds correlate with dissociation and aversive arousal in patients with borderline personality disorder

In addition to reduced pain perception, patients with borderline personality disorder (BPD) show higher pain thresholds under subjective stress conditions as compared with non-stress conditions. However, the correlation between symptoms of stress and pain thresholds has not been investigated so far. Using a new and convenient methodology, electric stimulation, we expected higher pain and detection thresholds in patients with BPD than in to healthy controls as well as a positive correlation between pain thresholds and symptoms of stress (aversive arousal and dissociation) in BPD patients. Twelve female patients with BPD and twelve healthy controls were included in the study. Electric stimulation was applied on the right index finger, and detection and pain thresholds were assessed by gradually intensifying the stimuli. We found significantly elevated pain thresholds in patients with BPD as compared with healthy controls, but no difference between patients and controls in detection thresholds. In patients, a significant positive correlation was revealed between pain thresholds and dissociation as well as between pain thresholds and aversive arousal. Besides demonstrating a close correlation between pain thresholds and symptoms of stress in patients with BPD, this study replicated earlier findings of reduced pain perception in patients with BPD. Measuring electric pain thresholds is a valid and reasonable method for larger studies.

Differential diagnosis and comorbidity of attention-deficit/hyperactivity disorder (ADHD) and borderline personality disorder (BPD) in adults.

Attention-deficit/hyperactivity disorder (ADHD) in adults and borderline personality Disorder (BPD) share some similar clinical features (e. g. impulsivity, emotional dysregulation, cognitive impairment). ADHD in childhood has been reported to be highly associated with the diagnosis of BPD in adulthood and adult ADHD often co-occurs with BPD. Treatment studies revealed an efficacy of dialectical behavioral therapy (DBT) and DBT-based psychotherapy, respectively, in BPD and adult ADHD as well as neuroimaging and psychopharmacological studies showed some evidence for a potential common neurobiological dysfunction suggesting the hypothesis that ADHD and BPD may not be two distinct disorders, but represent at least in a subgroup of patients two dimensions of one disorder.

Twenty-four-week treatment with extended release methylphenidate improves emotional symptoms in adult ADHD

Abstract Objectives. Treatment investigations with methylphenidate in adults with ADHD focus preferentially on the classical psychopathology: inattention, hyperactivity and impulsivity. ADHD-associated emotional symptoms, which are frequently present at least in ADHD subpopulations, were studied rarely. The vast majority of the placebo-controlled trials had observation periods between 4 and 8 weeks. To assess the medium- to long-term effects of extended release methylphenidate (MPH-ER) on emotional symptoms and other psychopathology frequently seen in ADHD patients, we conducted a large-scale, multicenter treatment study. Methods. We performed a randomised, 24-week, double-blind, placebo-controlled study in adults with ADHD. The diagnosis was made on the basis of the DSM-IV criteria, which were confirmed by clinical history and a structured psychopathological interview and the use of rating instruments. 363 patients were randomized to MPH-ER or placebo at a ratio of 2:1. The duration of the titration period was 5 weeks followed by a maintainance phase of 19 weeks. The efficacy measures were the observer rated 10-item Emotional Dysregulation Scale (EDS) derived from the Wender-Reimherr Adult Attention Deficit Disorder Scale (WRAADDS) and a self-report, six-item Emotional Lability Scale (ELS) extracted from the long version of the Conners Adult ADHD Self Report Scale (CAARS:S:L). In addition we used the SCL-90-R for the assessment of ADHD associated and comorbid psychopathology. Results. MPH-ER was statistically superior to placebo in reducing emotional symptoms as assessed by the EDS and the ELS. Obsessive-compulsive symptoms and those of problems with self-concept declined until the end of the observation period. The decline was more pronounced in MPH-ER treated individuals. The effects remained robust during the entire maintenance period until week 24. Symptoms of anxiety, depression, anger and hostility, phobia, paranoid ideations and psychoticism were not improved. Conclusions. MPH-ER appears to be an efficacious treatment for emotional symptoms with ADHD. Also obsessive-compulsive symptoms and problems with self-concept were affected positively.

Orbitofrontal reward sensitivity and impulsivity in adult attention deficit hyperactivity disorder

Impulsivity symptoms of adult attention deficit hyperactivity disorder (ADHD) such as increased risk taking have been linked with impaired reward processing. Previous studies have focused on reward anticipation or on rewarded executive functioning tasks and have described a striatal hyporesponsiveness and orbitofrontal alterations in adult and adolescent ADHD. Passive reward delivery and its link to behavioral impulsivity are less well understood. To study this crucial aspect of reward processing we used functional magnetic resonance imaging (fMRI) combined with electrodermal assessment in male and female adult ADHD patients (N=28) and matched healthy control participants (N=28) during delivery of monetary and non-monetary rewards. Further, two behavioral tasks assessed risky decision making (game of dice task) and delay discounting. Results indicated that both groups activated ventral and dorsal striatum and the medial orbitofrontal cortex (mOFC) in response to high-incentive (i.e. monetary) rewards. A similar, albeit less strong activation pattern was found for low-incentive (i.e. non-monetary) rewards. Group differences emerged when comparing high and low incentive rewards directly: activation in the mOFC coded for the motivational change in reward delivery in healthy controls, but not ADHD patients. Additionally, this dysfunctional mOFC activity in patients correlated with risky decision making and delay discounting and was paralleled by physiological arousal. Together, these results suggest that the mOFC codes reward value and type in healthy individuals whereas this function is deficient in ADHD. The brain-behavior correlations suggest that this deficit might be related to behavioral impulsivity. Reward value processing difficulties in ADHD should be considered when assessing reward anticipation and emotional learning in research and applied settings.

Association between Obesity and Adult Attention-Deficit/Hyperactivity Disorder in a German Community-Based Sample

Objective: The goal of the present study was to examine the association between attention-deficit/hyperactivity disorder (ADHD) and obesity in a representative community based sample of the German population. Method: Participants were 1,633 German residents (53.6% female) aged 18–64 years. A retrospective assessment of childhood ADHD and a self-report assessment of adult ADHD were administered for diagnosis of adult ADHD. In addition, binge eating and purging behaviors as well as depression and anxiety were assessed using selfrating instruments. Results: The estimated prevalence of ADHD in obese participants was 9.7% compared to 3.8% in overweight and 4.3% in under-/normal-weight participants. The prevalence of obesity was 22.1% among adults with ADHD and 10.2% among persons without ADHD. Adult ADHD was significantly associated with a greater likelihood of being obese but not overweight even after adjusting for sociodemographic characteristics. Results were similar when adjusting for depression and anxiety symptoms and for purging behaviors. Odds ratios decreased after adjusting for binge eating; however, the results were still significant which shows that the relationship between obesity and ADHD in adulthood is not fully explained by binge eating. Conclusion: Overall, the results indicate that adult ADHD is associated with obesity in a community-based sample of the adult German population.
