          To investigate impulsive behaviors in pathological buying (PB).


          The study included three groups matched for age and gender: treatment seeking outpatients with PB (PB+), treatment seeking psychiatric inpatients without PB (PB−), and a healthy control group (HC). PB was assessed by means of the Compulsive Buying Scale and by the impulse control disorder (ICD) module of the research version of the Structured Clinical Interview for DSM-IV (SCID-ICD). All participants answered questionnaires concerning symptoms of borderline personality disorder, self-harming behaviors, binge eating and symptoms of attention deficit and hyperactivity disorder (ADHD). In addition, comorbid ICDs were assessed using the SCID-ICD.


          The PB+ and PB− groups did not differ with regard to borderline personality disorder or ADHD symptoms, but both groups reported significantly more symptoms than the HC group. Frequencies of self-harming behaviors did not differ between the three groups. Patients with PB were more often diagnosed with any current ICD (excluding PB) compared to those without PB and the HC group (38.7% vs. 12.9% vs. 12.9%, respectively, p=.017).


          Our findings confirm prior research suggesting more impulsive behaviors in patients with and without PB compared to healthy controls. The results of the questionnaire-based assessment indicate that outpatients with PB perceive themselves equally impulsive and self-harm as frequently as inpatients without PB; but they seem to suffer more often from an ICD as assessed by means of an interview.

            Emotion-based dispositions to rash action: positive and negative urgency.

            Under heightened emotional states, individuals are more inclined to engage in ill-considered or rash actions than at other times. The authors present evidence for the existence of 2 related traits called positive and negative urgency. The traits refer to individual differences in the disposition to engage in rash action when experiencing extreme positive and negative affect, respectively. The authors provide evidence that these traits are distinct from other dispositions toward rash action and that they play distinct roles in predicting problem levels of involvement in behaviors such as alcohol consumption, binge eating, drug use, and risky sexual behavior. The authors identify facilitative conditions for the emergence of the urgency traits from neuroscience. Certain gene polymorphisms are associated with low levels of serotonin and high levels of dopamine; that pattern of neurotransmitter activity in a brain system linking the orbitofrontal cortex and the amygdala appears to facilitate the development of positive and negative urgency. The authors discuss the implications of this theory.

              The short version of the Borderline Symptom List (BSL-23): development and initial data on psychometric properties.

              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. 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. 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 alpha: 0.935-0.969; BSL-95/Cronbach's alpha: 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). 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. (c) 2008 S. Karger AG, Basel.
