Telephone-administered cognitive behavior therapy for obsessive-compulsive disorder

Exposure with response prevention and cognitive behavior therapy are widely recognized as effective treatments for obsessive-compulsive disorder. Unfortunately, many people with obsessive-compulsive disorder--particularly those living in rural areas--do not have access to therapists providing these treatments. Accordingly, we investigated the efficacy of telephone-administered cognitive behavior therapy for obsessive-compulsive disorder. Two open trials are reported, for a total of 33 people with obsessive-compulsive disorder (without major depression). The first trial consisted of 12 weeks on a waiting list followed by 12 weeks of treatment (delayed treatment). The second trial consisted of 12 weeks of immediate treatment. Obsessive-compulsive symptoms did not change during the waiting period. Symptoms declined from pre- to post-treatment, with gains maintained at 12-week follow-up. For the pooled sample our pre-to-post-treatment effect size was as large or larger than those obtained in other studies of reduced contact treatment, and similar to those of face-to-face exposure with response prevention. Our proportion of treatment dropouts tended to be lower than those of other reduced contact interventions. The results suggest that telephone-administered cognitive behavior therapy is effective and well-tolerated, at least for people with obsessive-compulsive disorder without major depression. It remains to be seen whether this treatment is safe and effective when comorbid major depression is present.     

Web-based research: Methodological variables’ effects on dropout and sample characteristics

Previous research has made a beginning in addressing the importance of methodological differences in Web-based research. The present paper presents four studies investigating whether sample type, financial incentives, time when personal information is requested, table design, and method of obtaining informed consent influence dropout and sample characteristics(both demographics and measured attitudes). Undergraduates were less likely to drop out than nonstudents, and nonstudents offered a financial incentive were less likely to drop out than those offered no incentive. Complex tables, tables that were too wide, requests for personal information on the first page, and the imposing of additional informed consent procedures each provoked early dropout. As was expected, nonstudents and those presented with complex tables showed more measurement error and attitude differences. Asking for personal information and imposing additional consent procedures affected the demographic makeup, raising challenges to external validity.     

Individual solution processes while solving addition and multiplication math facts in adults

Contrary to predictions of current solution process models, adults used a variety of procedures other than retrieval to solve addition and multiplication math facts. Predictors assumed to capture retrieval processes posited by such models did account for a substantial proportion of variance in averaged retrieval solution times. But most of the variance in individual participants' retrieval times remained unaccounted for. Cross-operation associations in patterns of strategy use and retrieval latencies were obtained. Adults with stronger higher level math achievement were more likely to use retrieval, solved math facts faster and less variably, and executed retrieval processes posited by current solution process models faster than participants with less math attainment. The results are explained within the context of the adaptive strategy choice model.     

Understanding the Dynamics of Leadership: The Role of Follower Self-Concepts in the Leader/Follower Relationship

In this paper we integrate recent theory and research on the self-concept with leadership theory. We conceptualize the self as being defined at three levels: the individual, interpersonal, and group levels. The effects of the self on information processing and behavior are mediated by the working self-concept, which is composed of self-views, possible selves, and goals (standards). Leaders are seen as producing short-run changes by influencing the working self-concept and more enduring changes through the development of chronic schema. Subordinates are also seen as influencing leaders' self-schema, both individually and collectively. Both practical and theoretical implications of this perspective are discussed.     

On the distinction between visual salience and stimulus-driven attentional capture.

It is often assumed that the efficient detection of salient visual objects in search reflects stimulus-driven attentional capture. Evidence for this assumption, however, comes from tasks in which the salient object is task relevant and therefore may elicit a deliberate deployment of attention. In 9 experiments, participants searched for a nonsalient target (vertical among tilted bars). In each display, 1 bar was highly salient in a different dimension (e.g., color or motion). When the target and salient elements coincided only rarely, reducing the incentive to attend deliberately to the salient stimuli, response times depended little on whether the target was salient, although some interesting exceptions were observed. It is concluded that efficient selection of an element in visual search does not constitute evidence that the element captures attention in a purely stimulus-driven fashion.     

Remote Odor Memory in Alzheimer's Disease: Deficits as Measured by Familiarity

Deficit in olfaction and remote nonolfactory memory in Alzheimer's disease (AD) motivated the present study of remote memory for odors and faces, operationally defined as rated familiarity, in patients with AD and controls. Uncommon engineering symbols were rated for familiarity to ensure task comprehension. Results showed that patients with AD rate odors, but not faces, as significantly less familiar than do controls, which is indicative of deficit in remote odor memory. Follow-up testing 1 year later again showed this result. Poor odor-detection sensitivity in patients, with AD, but lack of significant correspondence between sensitivity and familiarity, suggests an existing but limited effect of sensitivity on familiarity. The findings provide further evidence that olfaction may be a useful modality for early identification of AD.     

Employment Characteristics and Salaries of Psychologists in United States Medical Schools: Past and Current Trends

In 1997 the Research Office of the American Psychological Association (APA) collaborated with the Association of Medical School Psychologists (AMSP) to conduct a comprehensive employment and salary survey of psychologists employed in medical schools and academic health centers. Questionnaires were mailed to 3894 psychologists; postcard reminders and a follow-up mailing to nonresponders resulted in a final 50% response rate. The questionnaire addressed appointment characteristics, department and school characteristics, employment activities, salary information, demographics, and changes in the medical school work environment that have occurred as a result of managed care. This survey, the 1997 Employment Characteristics and Salaries of Medical School Psychologists, is the most comprehensive analysis to date of the practice of psychology in U.S. schools of medicine and academic health centers. This article reports the most salient findings from this survey.     

Expression of Fos and Jun Proteins Following Passive Avoidance Training in the Day-Old Chick

It has been shown previously that the immediate-early genes, c-fos and c-jun mRNA are induced in the 1-day-old chick forebrain after one-trial passive avoidance training in which chicks learn to avoid pecking at a bitter-tasting bead. Here, we have studied the expression of their proteins using antibodies to Fos and Jun. Western blotting disclosed two immunoreactive bands for the anti-Fos antibody (47 and 54 kD) and two immunoreactive bands for the anti-Jun antibody (39 and 54 kD). Two hours post-training there was an increase in the number of Fos-positive stained nuclei in right intermediate medial hyperstriatum ventrale (IMHV) (P<0.01), left IMHV (P<0.05), right lobus parolfactorius (LPO) (P<0.025) and left LPO (P<0.05) of birds trained on the bitter bead compared with controls that had pecked a water-coated bead. Staining for Jun protein was significantly greater in the right LPO of trained chicks (P<0.01). Other forebrain regions showed no increase over quiet control levels. The findings are discussed in the context of the cascade of events involved in passive avoidance memory consolidation in the day-old chick.     

Risk of sexual revictimization: A theoretical model

Survivors of child sexual abuse suffer serious short- and long-term psychological consequences. Sexual revictimization as an adult is one of the consequences that has been reported. At present, there is no theoretical model identifying the risk factors that result in child sexual abuse survivors being at greater risk of experiencing an adult sexual assault. The proposed model is designed to integrate existing research, stimulate further empirical work, and eventually aid in the development of a program to prevent revictimization. The variables hypothesized to play a mediating role in the pathway to revictimization include: severe psychological symptoms as a consequence of the child sexual abuse, poor coping styles, an insecure attachment style, hyperfemininity, delinquent behavior, drug use, and high risk sexual behavior.     

Comorbidity of Hyperactivity-Impulsivity-Inattention and Conduct Problems: Risk Factors in Social, Affective, and Academic Domains

Children showing a comorbid behavior pattern of hyperactivity-impulsivity-inattention and conduct problems (HIA + CP) were contrasted to children having only an internalizing and externalizing behavior pattern (I + E) and matched controls. Children displaying the HIA + CP behavior pattern were at greater risk on a number of outcome measures in social and academic domains beginning in Grade 3 and continuing into Grade 4. The most marked differences among the three groups were found on peer measures of rejection and friendship and teacher ratings of social skills. On average, almost two-thirds of the HIA + CP group were rejected by their peers compared to one-third of the I + E group and only 12.5% controls. Over 70% of the HIA + CP group had no reciprocated friendships from Grade 3 to Grade 4 compared to less than half of the I + E group and approximately one-fourth of controls. Contrary to much theorizing in the literature, the HIA + CP and I + E groups showed average levels of academic self-concept and did not differ from controls in on measures of social self-concept and academic self-concept and general self-esteem. These findings were interpreted in light of positive illusory biases and the established link between aggressive behavior and egotism. The current article offers partial support for Lynam's (1996) notion of the fledgling psychopath.
