The relationship of the Yale-Brown Obsessive Compulsive Scale (YBOCS) to other measures of obsessive compulsive symptoms in a nonclinical population

The Yale-Brown Obsessive Compulsive Scale (YBOCS; Goodman, Price, Rasmussen, & Mazure, 1989a) is an interview-based rating scale measuring severity of obsessive compulsive disorder (OCD). Because it is independent of the number and type of OCD symptoms and minimizes confounding with other types of symptoms, it has become the "gold standard" for assessing the outcome of behavioral and pharmacological treatments. This study was designed to further validate the YBOCS in relation to self-report measures of obsessive compulsive phenomena in a nonclinical population. Among a group of 45 female college students, the three primary YBOCS measures (obsessions, compulsions, and total score) were internally consistent and correlated moderately to strongly with self-report measures of obsessive compulsive phenomena that have been used in previous research. The compulsive subscale of the YBOCS showed the lowest correlation with self-report measures sharing only 25% of the common variance. This measure is appropriate for use with nonclinical samples and may prove superior to other instruments for detecting the presence and severity of obsessive and compulsive symptoms.     

Learning with arbitrary versus ecological conditioned stimuli: Evidence from sexual conditioning

Laboratory investigations of Pavlovian conditioning typically involve the association of an arbitrary conditioned stimulus (CS) with an unconditioned stimulus (US) that has no inherent relation to the CS. However, arbitrary CSs are unlikely to become conditioned outside the laboratory, because they do not occur often enough with the US to result in an association. Learning under natural circumstances is likely only if the CS has a preexisting relation to the US. Recent studies of sexual conditioning have shown that in contrast to an arbitrary CS, an ecologically relevant CS is resistant to blocking, extinction, and increases in the CS-US interval and results in sensitized responding and stronger second-order conditioning. Although the mechanisms of these effects are not fully understood, these findings have shown that signature learning phenomena are significantly altered when the kinds of stimuli that are likely to become conditioned under natural circumstances are used. The implications of these findings for an ecological approach to the study of learning are discussed.     

Attributing Problem-Solving to God,Receiving Social Support,and Stress-Moderation

This research note explores the stress-moderating effects of attributing a problem-solving role to God among a nationwide sample of 2,260 Americans. Specifically, the ways in which the perception of “God-as-a-problem-solver” moderates stress is explored for Americans reporting low and high levels of social support from other people. Within a model that interacts two moderators (i.e., a moderated moderation analysis), two predictions are tested that extend from social support and sense of control frameworks. Consistent with one prediction, viewing God-as-a-problem-solver had a stress-buffering effect (i.e., a reduction of the negative impact of life stressors on a depressive symptomology outcome measure) among those receiving low social support. Consistent with a second prediction, viewing God-as-a-problem-solver served as a stress-exacerbator among those already receiving high levels of social support. Findings suggest that the optimal count of supportive sets of entities (be it God or other people) is no fewer or no more than one.     

Depressive symptoms among women employed outside the home

Researchers who attempt to explain why paid employment is a source of psychological distress for some women must consider how a number of factors in the work and nonoccupational environments influence a woman's reaction to employment outside the home. We examined four aspects of the job that may be a source of distress for working women: job dissatisfaction, pay dissatisfaction, commitment to the work role, and full versus part-time employment. Of these, pay dissatisfaction and commitment to the work role emerged as significant predictors of depressive symptoms. With regard to home-related roles, neither help with housework nor the presence of young children in the home exerted a significant direct effect on psychological distress. Young children at home did, however, have a significant interaction effect with a woman's sex role beliefs. Finally, the presence of a conflict between the work and home roles was also a significant predictor of depression.     

Diagnostic value of alpha 1-acid glycoprotein in the cerebrospinal fluid

Samples from 1415 neurological patients were used to study the diagnostic value of acid alpha 1-glycoprotein in the lumbar cerebrospinal fluid. The value of analysis for this substance is considered to lie in the detection of non-specific acute-phase reactions of various causes in the CNS with special reference to barrier problems. The large number of pathologically elevated values associated with acute inflammations of the meninges and cerebral parenchyme is particularly striking. The results of the studies are analyzed on the basis of comprehensive control investigations (n = 559).     

Computer tomography and electromyography studies in patients with traumatic neuropathy

Combined computerized tomography and neurophysiological techniques permit the simultaneous assessment of morphological and functional aspects associated with traumatic neuropathy. The simultaneous application of such techniques is one way of optimizing status analysis and prognosis .     

Prospective study of the late sequelae of electroconvulsive treatment

In a prospective pilot study 1-3 years after no less than 5 ECT. 12 patients were examined clinically, and by means of psychological tests and computer-aided tomography. Convincing indications of lasting therapy-determined brain damages could not be found.     

Relative alpha desynchronization and synchronization during perception of music

Relative desynchronization (ERD) and synchronization (ERS) of the 8–10 Hz and 10–12 Hz alpha freqency bands elicited by music were studied in ten musically untrained right-handed subjects. The subjects listened to two five-minute musical excerpts representing two different musical genres, popular and classical, presented both foward and backward. ERD/ERS of the two alpha frequency bands was examined during the first four minutes of stimulus presentation using one-minute time windows. The results demonstrated that both the 8–10 Hz and the 10–12Hz frequency band exhibited reactivity to musical stimuli. The responses of the 8–10Hz and 10–12 Hz alpha frequency bands were dissimilar, dymanic and dependent on both time and stimulation type. The dynamics of these changes over time may explain some discrepancies in earlier EEG studies during listening to music.
