Special series Subtypes of obsessive-compulsive disorder: Introduction

An accumulating body of research suggests that obsessive-compulsive disorder (OCD) is a heterogeneous condition, yet there is not yet a consensus on how best to conceptualize subtypes or dimensions of the disorder. This special series considers theoretical and practical issues pertaining to OCD subtypes. New possibilities for conceptualizing differences among OCD patients are considered, and avenues for treating different presentations of obsessions and compulsions are discussed. Treatment programs continue to be refined and outcome studies continue to demonstrate that tailoring cognitive-behavioral treatment toward specific presentations of OCD (e.g., contamination fears, severe obsessions) represents the future of OCD treatment. The articles in this special series are intended to further efforts to consider ways of better understanding the heterogeneity of OCD.     

Predicting Creativity Based on the Facets of the Theoretical Intellect Framework

The present study investigates how the construct intellect, according to the Theoretical Intellect Framework (TIF), predicts creativity. The TIF is a theoretical model describing the structure of the construct intellect, a sub‐dimension of the Big Five domain openness to experience. People (N = 2709) from two sub‐samples (undergraduate students and Amazon MTurkers) completed one of three creativity tasks (self‐reported, remote associates, or rated photo caption) and the Intellect Scale. The results support hypotheses derived from the TIF, as the operation Create, rather than the operations Think or Learn, significantly and in some cases uniquely predicted the self‐reported creativity indicators. Creativity indicators with a strong cognitive load (remote associates test and rated photo caption), however, were predicted by the operation Think. Results are discussed with regards to the nomological net of the operation Create and the construct validity of the creativity assessments. We provide implications for applied purposes and call for further examination of the TIF with additional creativity measures. Copyright © 2015 European Association of Personality Psychology     

Effect of continuing care for people with cocaine dependence on criminal justice sentences

While continuing care for substance use treatment has been associated with reduced involvement in the criminal justice system, much of this research lacks random assignment to continuing care and so is limited by self‐selection bias. This study sought to determine the impact of adding telephone‐based continuing care to intensive outpatient programs on criminal justice outcomes for people with cocaine dependence. In three continuing care studies, spanning 1998–2008, participants were randomly assigned to an intensive outpatient program or an intensive outpatient program plus a telephone‐based continuing care intervention. Cocaine‐dependent participants from these three studies were included in the analyses, with outcomes derived from a dataset of jurisdiction‐wide criminal sentences from a state sentencing agency. Multiple logistic regression was employed to examine the odds of a criminal conviction occurring in the 4 years after enrollment in a continuing care study. The results showed that, controlling for a criminal sentence in the previous year, gender, age, and continuing care study, people with cocaine dependence randomized to an intensive outpatient program plus a telephone‐based continuing care intervention had 54% lower odds (p = 0.05, odds ratio = 0.46, 95% CI: 0.20–1.02) of a criminal sentence in the 4 years after enrollment in the continuing care study, compared with those randomized to an intensive outpatient program alone. We can conclude that adding telephone monitoring and counseling to intensive outpatient programs is associated with fewer criminal convictions over a 4‐year follow‐up period compared with intensive outpatient programs alone.     

Does the "eyes lead the hand" principle apply to reach-to-grasp movements evoked by unexpected balance perturbations?

A fundamental principle that has emerged from studies of natural gaze behavior is that goal-directed arm movements are typically guided by a saccade to the target. In this study, we evaluated a hypothesis that this principle does not apply to rapid reach-to-grasp movements evoked by sudden unexpected balance perturbations. These perturbations involved forward translation of a large (2 × 6 m) motion platform configured to simulate a “real-life” environment. Subjects performed a common “daily-life” visuo-cognitive task (find a telephone and make a call) that required walking to the end of the platform, which was triggered to move as they approached a handrail mounted alongside the travel path. A deception was used to ensure that the perturbation was truly unexpected. Eleven of 18 healthy young-adult subjects (age 22-30) reached to grasp or touch the rail in response to the balance perturbation. In support of the hypothesis, none of these arm reactions was guided by concurrent visual fixation of the handrail. Seven of the 11 looked at the rail upon first entering the environment, and hence may have used “stored” central-field information about the handrail location to guide the subsequent arm reaction. However, the other four subjects never looked directly at the rail, indicating a complete reliance on peripheral vision. These findings add to previous evidence of distinctions in the CNS control of volitional and perturbation-evoked arm movements. Future studies will determine whether similar visuo-motor behavior occurs when the available handhold is smaller or when subjects are not engaged in a concurrent visuo-cognitive task.     

Is Relational Demography Relative? How Employment Status Influences Effects of Supervisor–Subordinate Demographic Similarity

Purpose  

Because diversity is vital to many businesses, it is important to understand how demographic differences between individuals in the workplace influence employee behavior. In this study, we focused on demographic similarity (i.e., sex, racioethnicity) with one’s supervisor as a predictor of employee withdrawal. Further, we examined employees’ employment status (i.e., part-time vs. full-time) as a moderator of the similarity–withdrawal relationships.     

A reexamination of black-white mean differences in work performance: more data, more moderators

This study is the largest meta-analysis to date of Black-White mean differences in work performance. The authors examined several moderators not addressed in previous research. Findings indicate that mean racial differences in performance favor Whites (d = 0.27). Effect sizes were most strongly moderated by criterion type and the cognitive loading of criteria, whereas data source and measurement level were influential moderators to a lesser extent. Greater mean differences were found for highly cognitively loaded criteria, data reported in unpublished sources, and for performance measures consisting of multiple item scales. On the basis of these findings, the authors hypothesize several potential determinants of mean racial differences in job performance.     

Suspensions and detentions in an urban,low-income school: punishment or reward?

Disciplinary records for 3rd through 8th grade students (n = 314) in an inner-city, public school were examined for one school year to assess students' variation in response to discipline. Rates of disciplinary referrals were compared for students who received no detentions or suspensions throughout the year (never group n = 117), students who received one or more detention or suspension in the fall but not in the spring (fall group n = 62), and students who received one or more detention or suspension in the fall and one or more detention or suspension in the spring (fall + spring group n = 75). Results indicated that during the fall, the fall group had nearly equivalent rates of referrals to the fall + spring group; however, the fall group exhibited significantly lower rates of referrals during winter and spring that were nearly equivalent to the never group, as would be expected for a punishment procedure. In contrast, the fall + spring group evidenced increases in referrals across the year, suggesting the possibility that detentions and suspensions were functioning as rewards for this group. The fall + spring group was rated by teachers and peers at mid-year as highly aggressive, lacking social skills, and high on hyperactivity, whereas the fall group and the never group were statistically equivalent on teacher and peer ratings. Implications for mental health programs for urban schools are discussed, especially the need for alternatives to detention and suspension for the subset of students who account for the majority of school discipline.     

Specificity of measures of thought control

The rebound effect (D. M. Wegner, 1994) essentially involves the persistence of thought when an effort has been made to suppress the cognitive activity. Some of the research in this area has been directed at determining personal factors that predict differential levels of rebound. To this end, measures of thought control have emerged. In the present study the authors examined the properties of 2 measures of thought control: the Thought Control Questionnaire (TCQ; A. Wells & M. I. Davies, 1994) and the White Bear Suppression Inventory (WBSI; D. M. Wegner & S. Zanakos, 1994). Each measure was examined in relation to measures of obsessive-compulsive symptoms and worry, as well as combined factorial structure. Scores generally indicated that items on the Worry and Punishment subscales of the TCQ were highly related to worry and obsessive-compulsive symptoms, whereas scores on the WBSI showed an association between Worry and 1 subscale (Slowness) of obsessive-compulsive symptoms. Results of a principal components analysis indicate that, in the aggregate, the items from the TCQ and WBSI form 2 factors: Dysfunctional and Functional Thought Control Strategies. From these data, it appears that the TCQ possesses greater potential to predict performance in rebound experiments and has greater clinical usefulness. Future research directions involving the TCQ are recommended.     

The Probability of Collective Choice with Shared Knowledge Structures

Complex decision making typically involves many agents attempting to aggregate many alternatives. If agents' preferences are unconstrained, cyclic outcomes are highly probable. In contrast, we show that if agents share similar models of the choice domain, then a stable collective outcome occurs with about 90% probability. These results have implications for systems of interacting agents, such as group decisions by individuals in social settings or interpretations of sense data by competing perceptual modules of a brain.     

Hierarchical structure of dysfunctional beliefs in obsessive-compulsive disorder

The Obsessive Beliefs Questionnaire was developed as a comprehensive measure of dysfunctional beliefs, which cognitive models consider to be etiologically related to obsessive-compulsive disorder. Obsessive Beliefs Questionnaire subscales tend to be highly correlated, which raises the question of whether obsessive-compulsive-related beliefs are hierarchically structured, consisting of lower-order factors loading on 1 or more higher-order factors. To investigate the nature and relative importance of these factors, a hierarchical factor analysis was conducted (n = 202 obsessive-compulsive disorder patients), using a Schmid-Leiman transformation. Results indicated a higher-order (general factor) and 3 lower-order factors: (i) responsibility and overestimation of threat, (ii) perfectionism and intolerance of uncertainty and (iii) importance and control of thoughts. The high-order factor accounted for more variance in Obsessive Beliefs Questionnaire scores (22%) than did the lower-order factors (6-7%), thereby underscoring the importance of the higher-order factor. Despite the importance of the higher-order factor, the lower-order factors significantly predicted unique variance in measures of obsessive-compulsive symptoms, including severity ratings of compulsions. These finding suggest that cognitive models of obsessive-compulsive disorder should take into consideration the hierarchic structure of obsessive-compulsive-related beliefs.
