Social phobia: individual response patterns and the effects of behavioral and cognitive interventions

In the present study, the role of individual response patterns in the treatment of social phobic patients was investigated. Seventy-four patients were diagnosed as social phobics. On the basis of extreme scores on a behavioral test (the Simulated Social Interaction Test) and on a cognitive measure (the Rational Behavior Inventory), the response patterns of 39 patients were analyzed, and the patients themselves were classified as either 'behavioral reactors' or 'cognitive reactors'. Half of the patients with each response pattern received a behavioral focused treatment, i.e. social skills training (SST), while the other half received a cognitive oriented treatment, i.e. rational emotive therapy (RET). Patients received group therapy in eight weekly sessions. Within-group differences showed a considerable improvement in all treatment groups. Between-group differences failed to lend support to the hypothesis that treatment that fits a response pattern (i.e. SST for behavioral reactors and RET for cognitive reactors) will result in a greater improvement than one that does not.     

The effects of poverty on the mental, emotional, and behavioral health of children and youth: implications for prevention

This article considers the implications for prevention science of recent advances in research on family poverty and children's mental, emotional, and behavioral health. First, we describe definitions of poverty and the conceptual and empirical challenges to estimating the causal effects of poverty on children's mental, emotional, and behavioral health. Second, we offer a conceptual framework that incorporates selection processes that affect who becomes poor as well as mechanisms through which poverty appears to influence child and youth mental health. Third, we use this conceptual framework to selectively review the growing literatures on the mechanisms through which family poverty influences the mental, emotional, and behavioral health of children. We illustrate how a better understanding of the mechanisms of effect by which poverty impacts children's mental, emotional, and behavioral health is valuable in designing effective preventive interventions for those in poverty. Fourth, we describe strategies to directly reduce poverty and the implications of these strategies for prevention. This article is one of three in a special section (see also Biglan, Flay, Embry, & Sandler, 2012; Mu?oz, Beardslee, & Leykin, 2012) representing an elaboration on a theme for prevention science developed by the 2009 report of the National Research Council and Institute of Medicine.     

Multilevel factorial experiments for developing behavioral interventions: power, sample size, and resource considerations

Factorial experimental designs have many potential advantages for behavioral scientists. For example, such designs may be useful in building more potent interventions by helping investigators to screen several candidate intervention components simultaneously and to decide which are likely to offer greater benefit before evaluating the intervention as a whole. However, sample size and power considerations may challenge investigators attempting to apply such designs, especially when the population of interest is multilevel (e.g., when students are nested within schools, or when employees are nested within organizations). In this article, we examine the feasibility of factorial experimental designs with multiple factors in a multilevel, clustered setting (i.e., of multilevel, multifactor experiments). We conduct Monte Carlo simulations to demonstrate how design elements-such as the number of clusters, the number of lower-level units, and the intraclass correlation-affect power. Our results suggest that multilevel, multifactor experiments are feasible for factor-screening purposes because of the economical properties of complete and fractional factorial experimental designs. We also discuss resources for sample size planning and power estimation for multilevel factorial experiments. These results are discussed from a resource management perspective, in which the goal is to choose a design that maximizes the scientific benefit using the resources available for an investigation.     

Acceptability of behavioral interventions: Perceptions of superintendents of public residential facilities

The acceptability of behavioral procedures has been examined with many groups of individuals that have significant roles in the lives of persons with mental retardation. However, for those individuals that live in public residential facilities, one critical person in the decision making process is the superintendent. The purpose of this study was to assess the acceptability of treatments to superintendents of public residential facilities. Using the Treatment Evaluation Inventory (Kazdin, 1980), superintendents rated the acceptability of five treatments (DRO, Time-out, medication, overcorrection and contingent shock) applied to a mild and severe behavior problem. The results showed a significant main effect for treatment and problem and a problem by treatment interaction. Acceptability was inversely related to treatment restrictiveness and, except for differential reinforcement of other behaviors (DRO), all treatments were more acceptable for the severe problem than for the mild problem.     

Social phobia: individual response patterns and the long-term effects of behavioral and cognitive interventions. A follow-up study

In this study the long-term effectiveness of Social Skills Training (SST) and Rational Emotive Therapy (RET), on social phobia was studied, as well as the differential influence of patient characteristics on treatment effectiveness. Fifty-seven patients were assessed 14 months after the post-test. Results showed that long-term effectiveness was independent of the response-pattern of the patients. Comparisons between methods, irrespective of the response-pattern of the patients, showed no differences in effectiveness in favor of either SST or RET. Explorative analysis indicated the potential predictive power for treatment-outcome of confederate ratings of overt behavior on the SSIT. Patients who needed additional treatment appeared to perform significantly worse on this measure at the pretest. No factors could be traced that predict relapse after a relatively successful treatment.     

JEAB Research Over Time: Species Used,Experimental Designs,Statistical Analyses,and Sex of Subjects

We examined the species used as subjects in every article published in the Journal of the Experimental Analysis of Behavior (JEAB) from 1958 through 2013. We also determined the sex of subjects in every article with human subjects (N = 524) and in an equal number of randomly selected articles with nonhuman subjects, as well as the general type of experimental designs used. Finally, the percentage of articles reporting an inferential statistic was determined at 5-year intervals. In all, 35,317 subjects were studied in 3,084 articles; pigeons ranked first and humans second in number used. Within-subject experimental designs were more popular than between-subjects designs regardless of whether human or nonhuman subjects were studied but were used in a higher percentage of articles with nonhumans (75.4 %) than in articles with humans (68.2 %). The percentage of articles reporting an inferential statistic has increased over time, and more than half of the articles published in 2005 and 2010 reported one. Researchers who publish in JEAB frequently depart from Skinner’s preferred research strategy, but it is not clear whether such departures are harmful. Finally, the sex of subjects was not reported in a sizable percentage of articles with both human and nonhuman subjects. This is an unfortunate oversight.     

Sensation seeking, impulsive decision-making, and risky sex: implications for risk-taking and design of interventions

In an HIV prevention study, 2949 ninth-grade students in 17 high schools in two Midwestern U.S. cities were administered scales measuring sensation seeking and impulsive decision-making and their separate and combined relationships to a number of indicators of sexual risk-taking. Measures of sexual risk-taking included intentions to have sex, ever had sex, number of lifetime sexual partners, been pregnant or caused a pregnancy, used a condom, used marijuana, had unwanted sex when drunk, had unwanted sex under pressure, said no to sex, used alcohol or partner used alcohol before sex. Strong associations were observed between each of the measures and sexual risk-taking for most of the indicators. Strongest associations were found among sexually active students high on both sensation seeking and impulsive decision-making and weakest associations among students low on both measures. Implications for design of interventions in health campaigns are discussed.     

Acceptability of positive and reductive behavioral interventions: Factors that influence teachers'' decisions

Treatment acceptability refers to individuals' judgments as to whether psychological treatment procedures are appropriate, fair, and reasonable for a given problem. In the present two-experiment study, experienced teachers' ratings of acceptability for positive (i.e., praise, home-based reinforcement, and token economy) and reductive (i.e., ignoring, response-cost lottery, and seclusion time-out) behavioral interventions were investigated. Using the Intervention Rating Profile (IRP) and a case study methodology to manipulate variables of intervention complexity and problem behavior severity, it was established that (a) teachers' acceptability ratings of both positive and reductive interventions varied with the severity of a target behavior, (b) the complexity of an intervention influenced teachers' ratings of acceptability, less complex or time-consuming interventions being rated generally more acceptable, and (c) mean acceptability ratings were significantly more favorable for positive than reductive treatments. These findings are discussed in the context of previous acceptability research and future investigations.     

The effects of unitization on familiarity-based source memory: testing a behavioral prediction derived from neuroimaging data

Performance on tests of source memory is typically based on recollection of contextual information associated with an item. However, recent neuroimaging results have suggested that the perirhinal cortex, a region thought to support familiarity-based item recognition, may support source attributions if source information is encoded as a feature of the relevant item (i.e., "unitized"). The authors hypothesized that familiarity may contribute to source memory performance if item and source information are unitized during encoding, whereas performance may rely more heavily on recollection if source information is encoded as an arbitrary contextual association. Three source recognition experiments examining receiver operating characteristics and response deadline performance indicated that familiarity makes a greater contribution to source memory if source and item information are unitized during encoding. These findings suggest that familiarity can contribute to source recognition and that its contribution depends critically on the way item and source information are initially processed.     

Rumination, worry, cognitive avoidance, and behavioral avoidance: examination of temporal effects

Recently, cross-sectional research has demonstrated that depressive rumination is significantly associated with the tendency to engage in cognitive and behavioral avoidance. This evidence suggests that rumination may be the result of attempts to avoid personally threatening thoughts, in a manner suggested by multiple contemporary theories of worry. This investigation examined the temporal relationship among daily levels of cognitive avoidance, behavioral avoidance, rumination, worry, and negative affect. Seventy-eight adolescents completed baseline questionnaires and then electronically completed daily measures of rumination, worry, behavioral avoidance, and cognitive avoidance, as well as sad and anxious affect for 7 days. Lagged-effect multilevel models indicated that increases in daily sadness were predicted by greater daily rumination and cognitive avoidance. Increases in daily anxiety were predicted by greater daily rumination, worry, and both cognitive and behavioral avoidance. Further, both daily rumination and worry were positively predicted by daily cognitive, but not behavioral, avoidance. Mediation analyses suggested that rumination mediated the effect of cognitive avoidance on both sadness and anxiety. Also, worry mediated the effect of cognitive avoidance on anxiety. Implications for models of avoidance, rumination, and worry are discussed.
