A randomized pilot trial comparing videoconference versus face-to-face delivery of behavior therapy for childhood tic disorders

Comprehensive Behavioral Intervention for Tics (CBIT) has been shown to be effective for reducing tics in children with chronic tic disorder. Unfortunately, there remain significant barriers to dissemination. The aim of the current study was to examine the effectiveness of CBIT delivered over videoconference. Twenty children were randomly assigned to receive CBIT over videoconference or via traditional face-to-face delivery. Results show that both treatment delivery modalities resulted in significant tic reduction with no between group differences. Furthermore, acceptability and therapist-client alliance ratings were strong for both groups. Together, these results suggest that videoconference is a viable option for disseminating CBIT.     

Item Response Theory with Estimation of the Latent Population Distribution Using Spline-Based Densities

The purpose of this paper is to introduce a new method for fitting item response theory models with the latent population distribution estimated from the data using splines. A spline-based density estimation system provides a flexible alternative to existing procedures that use a normal distribution, or a different functional form, for the population distribution. A simulation study shows that the new procedure is feasible in practice, and that when the latent distribution is not well approximated as normal, two-parameter logistic (2PL) item parameter estimates and expected a posteriori scores (EAPs) can be improved over what they would be with the normal model. An example with real data compares the new method and the extant empirical histogram approach.     

Juggling Through Hoops: Implementing Ethics Policies in Applied Language Studies

This article reports on a collective effort to position ethics policies within the context of a specific discipline – Applied Language Studies (ALS). Through a discussion of challenges to ALS-specific pedagogical and research practices, this article highlights (1) the need for consistency across institutional Research Ethics Boards in the application of general principles of ethics review, and (2) the recognition of local considerations that are informed by disciplinary approaches not envisioned in current ethics policies. Ethics policies that are driven by substantive ethical intent will recognize pedagogical practices, research methodologies, and epistemological values and traditions that mark a discipline.     

Irrationality profiles for anger and anxiety

A fundamental position in Rational-Emotive Therapy (RET) is that irrational belief systems cause emotional disturbance. This study adds to the body of recent research substantiating this position by showing significantly different profiles on the Jones Irrational Beliefs Test (IBT) (1968/1969) for a nonclinical population (N=446) differentiated according to low, medium, and high anxiety and low, medium, and high anger. The profile differences not only support the above fundamental position, but also offer some further evidence for the validity of the IBT.Paul J. Woods, Ph.D., co-editor of this journal, is an associate fellow of the Institute for Rational-Emotive Therapy, a professor of psychology at Hollins College, and is engaged in private practice in Roanoke, Virginia.Samuel K. Coggin is completing his Master's work at Hollins College and is employed as a psychologist at the Central Virginia Training Center, Lynchburg, Virginia.     

Effects of interpolating a secondary task during the intertrial interval of a concept identification problem

Several tasks were interpolated during the intertrial interval (ITI) of a concept identification (CI) task. In Experiment I, 234 subjects were required to count backwards by threes, emit a sibilant, or to refrain from thinking after all responses, after correct responses, or after errors. Counting backwards interfered with performance, but only if it occurred after errors. Stimulus and feedback information was either withheld, as in Experiment I, or made available during the ITI in Experiment II. Results of the data from 280 subjects indicated that counting backwards interfered with performance only when interpolated after errors, when stimulus-feedback information was withheld, but had an equivalent effect after errors and correct responses when stimulus-feedback information was available during ITI, indicating that different strategies were induced by the presence of such information.     

Trait attributions and defense against insult from a dissimilar other

It was hypothesized that subjects would prefer to blame a character assault on negative ability characteristics of a dissimilar attacker as opposed to negative motivational characteristics in order to escape responsibility for the attack. It was reasoned that because we generally think of ourselves as having less potential influence over the abilities as opposed to the motivations of another person, it might be possible to diminish one's responsibility for another's behavior by attributing that behavior to that person's ability characteristics. Subjects in this experiment responded either to an insulting or noninsulting stimulus person who was either similar or dissimilar by selecting from a list of both motivational and ability bipolar trait dimensions, those dimensions they would most prefer to use in rating the stimulus person. As predicted, subjects responding to an insulting and dissimilar stimulus person showed a significantly greater preference for ability trait dimensions than subjects in the other conditions combined and also disliked the stimulus person more. The significance of these results for defensive attribution processes and phenomena such as racism and sexism are discussed.     

Relative reinforcer magnitude under a nonindependent concurrent schedule of cocaine reinforcement in rhesus monkeys.

Lever pressing by three rhesus monkeys was maintained under a two-lever concurrent schedule of cocaine reinforcement. Responding on one lever (constant-dose lever) produced a constant dose of 0.05 or 0.1 mg/kg/injection arranged according to a variable-interval 1-min schedule. Responding on the other lever (variable-dose lever) produced a comparison dose of cocaine (0.013 to 0.8 mg/kg/injection), also under a variable-interval 1-min schedule. The two variable-interval schedules were made nonindependent by arranging that the assignment of a reinforcer by one schedule inactivated the second schedule until the assigned reinforcer had been obtained. This modification ensured that the two cocaine doses were obtained with approximately equal frequency, regardless of the distribution of the subject's responding. Preference, indicated by relative response frequency on the variable-dose lever, was almost always for the larger of the doses and was a monotonic function of the comparison dose, except at the highest doses. Preferences at the highest comparison doses may have resulted from the low overall response rates exhibited at these doses. Relative response frequencies on the variable-dose lever roughly matched relative reinforcer magnitude (mg/kg/injection available on the variable-dose lever divided by the sum of mg/kg/injections available on each lever).
