Nonconsensual Sexual Experiences in Precollege Women: Prevalence and Risk Factors

The authors of this study examined the prevalence of nonconsensual sexual experiences in dating situations among a sample of 330 incoming female college students. Results indicated that 38.5% of women reported experiencing at least one form of sexual victimization in dating, ranging from unwanted sexual contact to rape. Victimization was related to history of childhood sexual abuse as well as previous consensual sexual activity. Discussion focuses on the need for education and prevention programs during the secondary school years and counseling assistance for college-age victims.     

Ritanserin and voluntary alcohol intake in rats

In a previous study (Rammsayer & Vogel, 1991), rats selectively bred for high and low catecholamine responses to stress showed a selective response to the 5-HT2 receptor blocker ritanserin. However, it remained unclear whether selective breeding resulted in a decrease in 5-HT responsivity, as suggested by the lack of an effect in high stress responding rats, or in an increase in 5-HT responsivity, as suggested by ritanserin-induced reduction in alcohol intake in low-responding rats. To answer this question, nonselectively bred rats were forced to drink a 5% alcohol solution for 10 days. For the subsequent six days, animals were injected subcutaneously with 2.5 mg/kg/2 ml ritanserin or vehicle only, and both a 5% solution of alcohol and water were presented to the animals. Ritanserin neither affected alcohol nor total fluid intake suggesting that in the general population of N/NIH (Hansen) rats as well as in rats of the same strain selectively bred for high catecholamine responses, mesolimbic dopaminergic activity is not effectively modulated by specific blockade of 5-HT2 receptors. However, a very pronounced ritanserin induced difference in daily water intake between nonbred male and female rats became evident.     

Differential effects of a 5-HT2 receptor blocker on alcohol intake in rats selectively bred for high and low catecholamine responses to stress

The effect of the selective 5-HT2 receptor blocker ritanserin on alcohol consumption was investigated in two strains of rats selectively bred for high and low catecholamine responses to stress. Rats were forced to drink a 5% alcohol solution for 10 days. For the subsequent six days, animals were injected subcutaneously with 2.5 mg/kg/2 ml ritanserin or vehicle only, and both a 5% solution of alcohol and water were presented to the animals. Ritanserin affected neither water nor total fluid intake. Furthermore, no effect of ritanserin on alcohol consumption could be demonstrated in high-responding rats, whereas in low-responding rats a very pronounced ritanserin-induced reduction in alcohol intake was observed. Results are discussed in terms of mediating effects of serotonergic neurons on mesolimbic dopaminergic reward systems related to drug addiction.     

Mortality salience effects on reckless driving intentions in a motorcyclist sample: The moderating role of group riding

Campaigns against reckless driving often mention the risk of dying. Research on terror management theory indicates that death claims may backfire and foster reckless driving. Here, we studied such mortality salience effects in a motorcyclist sample. Two moderating variables, particularly interesting regarding the sample of motorcyclists, were considered: group riding (vs. riding alone) and driving‐related self‐esteem. Motorcyclists were exposed to a campaign, either highlighting mortality or not. Orthogonally, cyclists were primed with riding in a group (vs. riding alone). Driving‐related self‐esteem was assessed via a questionnaire. We predicted that reminders of riding in a group would buffer against ironic mortality effects. Supporting this hypothesis, mortality salience effects interacted with the group prime. The results indicate that death appeals are likely to backfire with cyclists riding alone rather than cyclists riding in a group, especially if motorcycling is relevant to the self.     

Examination of the Stigmas Toward Help Seeking Among Turkish College Students

This study builds on previous help‐seeking research in the United States by examining the role of counseling stigma in Turkey. Undergraduate students in Turkey (N = 520) completed self‐report measures of attitudes and intentions to seek counseling and 3 forms of help‐seeking stigma. Results indicated that perceptions of public and social network stigma each uniquely contributed to the experience of self‐stigma, which, in turn, influenced attitudes toward seeking counseling and then help‐seeking intentions.     

Change in metacognitions predicts outcome in obsessive–compulsive disorder patients undergoing treatment with exposure and response prevention

Wells' (Wells, A. (1997). Cognitive therapy of anxiety disorders: a practice manual and conceptual guide. Chichester, UK: Wiley) metacognitive model of obsessive–compulsive disorder (OCD) predicts that metacognitions must change in order for psychological treatment to be effective. The aim of this study was to explore: (1) if metacognitions change in patients undergoing exposure treatment for OCD; (2) to determine the extent to which cognitive and metacognitive change predicts symptom improvement and recovery. The sample consisted of 83 outpatients with a diagnosis of OCD who completed exposure and response prevention treatment. The Yale–Brown Obsessive–Compulsive Scale (Y-BOCS), the Metacognitions Questionnaire (MCQ-30) and the Obsessive Beliefs Questionnaire (OBQ-44) were administered before treatment, after treatment, and at 12-month follow-up. Treatment resulted in significant changes in symptoms, metacognition score, responsibility and perfectionism. Regression analysis using post-treatment Y-BOCS as the dependent variable indicated that when the overlap between predictors was controlled for, only changes in metacognition were significant. Changes in metacognitions explained 22% of the variance in symptoms at post-treatment when controlling for pre-treatment symptoms and changes in mood. A further regression revealed that two MCQ-30 subscales made individual contributions. The patients had significantly higher scores compared to community controls on the MCQ-30. Patients who achieved clinical significant change had lower scores on the MCQ-30 compared to patients who did not change. The results did not change significantly from post-treatment to follow-up assessment. These findings provide further support for the importance of metacognitions in treating OCD.     

Comparison of voice acquisition methodologies in speech research

The use of voice acoustic techniques has the potential to extend beyond work devoted purely to speech or vocal pathology. For this to occur, however, researchers and clinicians will require acquisition technologies that provide fast, accurate, and cost-effective methods for recording data. Therefore, the present study aimed to compare industry-standard techniques for acquiring high-quality acoustic signals (e.g., hard drive and solid-state recorder) with widely available and easy-to-use, computer-based (standard laptop) data-acquisition methods. Speech samples were simultaneously acquired from 15 healthy controls using all three methods and were analyzed using identical analysis techniques. Data from all three acquisition methods were directly compared using a variety of acoustic correlates. The results suggested that selected acoustic measures (e.g., f 0, noise-toharmonic ratio, number of pauses) were accurately obtained using all three methods; however, minimum recording standards were required for widely used measures of perturbation.
