“…Beck and colleagues (Beck et al 1988) reported high internal consistency (α=0.92), testretest reliability (r=0.75), and good discrimination of anxiety disorders from nonanxiety disorders over 1 week. The psychometric properties of the BAI have been further supported in clinical and nonclinical samples (Clark et al 1994;Hewitt and Norton 1993;Steer et al 1993). …”

Studies of PTSD employing symptom provocation have seldom included self-report measures of the symptoms provoked. Doing so could benefit psychobiological research by improving diagnostic discrimination and capturing the heterogeneity of responses to scriptdriven imagery, and treatment research by complementing existing outcome measures. This paper describes the initial development and psychometric properties of the Responses to Script-Driven Imagery Scale (RSDI), a brief self-report measure of state PTSD and dissociative symptoms evoked by script-driven imagery, a widely used symptom provocation method in PTSD research. Across three samples and three variants of the script-driven imagery paradigm, confirmatory factor analysis fit a hypothesized and sample-invariant three-factor structure for the RSDI, composed of reexperiencing, avoidance, and dissociative symptoms. Subscales exhibited acceptable to high internal consistency reliabilities, and construct validity evidence was strong and consistent with predictions. The RSDI shows promise as a tool for psychobiological and treatment outcome research on PTSD.

Does oral alprazolam affect ventilation? A randomised, double-blind, placebo-controlled trial

et al. 2008

The respiratory effects of benzodiazepines have been controversial. This investigation aimed to study the effects of oral alprazolam on ventilation. In a randomised, double-blind cross-over protocol, 20 healthy men ingested 1 mg of alprazolam or placebo in random order, 1 week apart. Ventilation was unobtrusively monitored by inductance plethysmography along with end-tidal PCO2 and pulse oximetry 60-160 min after drug intake. Subjects were encouraged to keep eyes open. Meanï¿(1/2)+/-was similar (6.21 +/-0.71 vs 6.41 +/-1.12 L/min, P = NS). End-tidal PCO2 and oxygen saturation did also not differ between treatments. However, coefficients of variation of minute ventilation after alprazolam exceeded those after placebo (43 +/-23% vs 31 +/-13%, P < 0.05). More encouragements to keep eyes open were required after alprazolam than after placebo (5.2 +/-5.7 vs 1.3 +/-2.3 calls, P < 0.05). In a multiple regression analysis, higher coefficients of variation of minute ventilation after alprazolam were related to a greater number of calls. Oral alprazolam in a mildly sedative dose has no clinically relevant effect on ventilation in healthy, awake men. The increased variability of ventilation on alprazolam seems related to vigilance fluctuations rather than to a direct drug effect on ventilation. In conclusion, oral alprazolam in a mildly sedative dose has no clinically relevant effect on ventilation in healthy, awake men. The increased variability of ventilation on alprazolam seems to derive from vigilance fluctuations rather than from a direct drug effect on ventilation.

Study Objectives: The hypocretin system enhances signaling in the mesolimbic pathways regulating reward processing and addiction. Because individuals with narcolepsy with cataplexy have low hypocretin levels, we hypothesized that they may be less prone to risk-and reward-seeking behaviors, including substance abuse. Design: Endpoints were performance on an array of psychometric tests (including the Eysenck Impulsiveness Scale, the Zuckerman Sensation Seeking Scale, the Gormally Binge Eating Scale, and the Beck Depression and Anxiety Inventory) and on the Balloon Analogue Risk Task (BART). Setting: Tertiary narcolepsy referral centers in Leiden (The Netherlands) and Boston (USA). Patients: Subjects with narcolepsy with cataplexy (n = 30), narcolepsy without cataplexy (n = 15), and controls (n = 32) matched for age, sex, and smoking behavior. Interventions: None. Measurements and Results: There was no difference in risktaking behavior between narcolepsy with or without cataplexy and the control group, as measured using the BART and the array of questionnaires. However, subjects in the narcolepsy with cataplexy group had significantly higher scores on the Eysenck Impulsiveness Scale (p < 0.05), with 10.0% categorized as impulsive, compared to 6.7% of the narcolepsy without cataplexy group and none of the controls. Narcoleptics with cataplexy also scored significantly higher than controls on the Binge Eating Scale (p < 0.05), with moderate or severe binge eating in 23%. On the depression and anxiety scales, all narcolepsy patients, especially those with cataplexy, scored significantly higher than controls. Conclusions:We found that narcoleptics with or without cataplexy generally have normal risk-taking behavior, but narcoleptics with cataplexy were more impulsive and more prone to binge eating than patients without cataplexy and controls. Our findings shed new light on the relation between sleepiness and impulsiveness. Furthermore, rates of depression and anxiety were higher in all narcoleptic subjects. However, using the current methods, no evidence could be found to support the hypothesis that hypocretin deficiency would affect reward-processing in humans.
