Specific fears as predictors of generalized anxiety in children

The study investigated the relationship between fear and anxiety in childhood. One hundred fifty-one children aged 6 to 11 years (mean=8.7 years) completed the Fear Survey Schedule for Children-Revised (FSSC-R) and the Revised Children's Manifest Anxiety Scale (RCMAS). Correlational analyses demonstrated that the FSSC-R and each of the fear factors were significantly correlated with each other and with the RCMAS score. A stepwise regression procedure was used to determine if the FSSC-R or any of its five factors was significantly related to scores on the RCMAS. Results indicated that Factor 1 (Failure and Criticism) accounted for 31% of the variance (p < .0001)and Factor 2 (Fear of the Unknown) accounted for an additional 1% of the variance (p < .03)in the RCMAS scores. The relationship between these results and those from a similar study with adults (Goetsch, Tishelman, & Adams, 1987), as well as how the results add to an understanding of childhood anxiety, is discussed.This study was supported by BRSG Grant S07RR0714917 from the Biomedical Research Support Grant Program, Division of Research Resources, National Institute of Health, to the Research Foundation of the State University of New York at Binghamton.     

Saying and doing: A commentary on a contingency-space analysis

This article addresses the contingency-space analysis (Matthews, Shimoff, & Catania, 1987) of the verbal regulation of behavior. From an applied perspective, the conceptualization of the relationship between saying and doing Matthews et al. present may be more complex than is necessary. The central issue in correspondence investigations is a simple one: does correspondence between what people say and what they do occur? The focus of this paper is on the applied and clinical importance of the relationship between verbalizations and relevant behavior and the implications for future research.     

Synthesizing concurrent interval performances

Concurrent schedules may be viewed as consisting of two pairs of stay and switch schedules, each pair associated with one of the alternatives. A stay schedule arranges reinforcers for staying and responding at one alternative, whereas the associated switch schedule arranges reinforcers for switching to the other alternative. In standard concurrent schedules, the stay schedule at each alternative is equivalent to the switch schedule at the other alternative. MacDonall (1999) exposed rats to one pair of stay and switch variable-ratio schedules and varied the response requirements across conditions. Combining results from symmetric pairs produced composite performances that were described by the generalized matching law. This outcome was noteworthy because the data were obtained from performances at two alternatives with contingencies that were functionally unrelated to each other. This result suggests that concurrent performances may consist of two unrelated performances that alternate as behavior moves between alternatives. The purpose of the present experiment was to extend those results to interval schedules. Rats were exposed to pairs of random-interval schedules, and across conditions their mean intervals were varied. When data from appropriately paired conditions were combined, the composite performances were consistent with the generalized matching law. In addition, the results supported two models of concurrent performances that were based on local variables at an alternative (behavior, and stay and switch reinforcers): a modified version of the contingency discrimination model (Davison & Jenkins, 1985) and the local model (MacDonall, 1999).     

Derived relational responding as generalized operant behavior

The major aim of the present study was to demonstrate that derived relational responding may be viewed as a form of generalized operant behavior. In Experiment 1, 4 subjects were divided into two conditions (2 in each condition). Using a two-comparison matching-to-sample procedure, all subjects were trained and tested for the formation of two combinatorially entailed relations. Subjects were trained and tested across multiple stimulus sets. Each set was composed of novel stimuli. Both Conditions 1 and 2 involved explicit performance-contingent feedback presented at the end of each block of test trials (i.e., delayed feedback). In Condition 1, feedback was accurate (consistent with the experimenter-designated relations) following exposure to the initial stimulus sets. When subjects' responding reached a predefined mastery criterion, the feedback then switched to inaccurate (not consistent with the experimenter-designated relations) until responding once again reached a predefined criterion. Condition 2 was similar to Condition 1, except that exposure to the initial stimulus sets was followed by inaccurate feedback and once the criterion was reached feedback switched to accurate. Once relational responding emerged and stabilized, response patterns on novel stimulus sets were controlled by the feedback delivered for previous stimulus sets. Experiment 2 replicated Experiment 1, except that during Conditions 3 and 4 four comparison stimuli were employed during training and testing. Experiment 3 was similar to Condition 1 of Experiment 1, except that after the mastery criterion was reached for class-consistent responding, feedback alternated from accurate to inaccurate across each successive stimulus set. Experiment 4 involved two types of feedback, one type following tests for mutual entailment and the other type following tests for combinatorial entailment. Results from this experiment demonstrated that mutual and combinatorial entailment may be controlled independently by accurate and inaccurate feedback. Overall, the data support the suggestion, made by relational frame theory, that derived relational responding is a form of generalized operant behavior.     

A randomized controlled pilot study evaluating Worry Less,Live More: The Mindful Way Through Anxiety Workbook

ABSTRACT

Effective interventions for generalized anxiety exist, but barriers to treatment prevent their broad dissemination. Commercially available self-help materials may help bridge this gap, but few have been empirically evaluated. This study compared self-reported change in generalized anxiety symptomology and associated problems between community members with excessive worry who were randomly assigned to receive the Worry Less, Live More: The Mindful Way through Anxiety Workbook (n = 35) and those in a delayed condition (n = 29). Participants in the workbook condition reported significantly greater reductions between baseline and 11-week follow-up in self-reported worry (η ² =.15), general anxiety/tension (η ² =.13), and anxiety (η ² =.24) than those in the delayed condition, although no statistically significant differences across condition on changes in depression, functional impairment or acceptance were detected. This pilot study provides support for continued research examining the efficacy of acceptance-based behavioral therapy delivered in a self-help format.
