Rumination is theorized to be a cognitive avoidance process that is implicated in several manifestations of psychopathology. Few interventions directly target rumination as a core process maintaining emotional disorder symptoms. This pilot study compared the feasibility and preliminary efficacy of self-directed behavioral approaches for reducing rumination. Participants (N = 60) with elevations in rumination were randomized to 3 weeks of self-directed interventions: (a) scheduled rumination time; (b) a strategy combining mindfulness, shaping, and disengagement strategies; or (c) self-monitoring control. Both active treatment conditions outperformed self-monitoring control on post-treatment depression scores. Scheduled rumination time significantly outperformed the other two conditions on measures of rumination and worry. No between-group differences emerged on the secondary outcome (i.e., anxiety symptoms). Brief, self-directed, behavioral interventions targeting rumination are feasible and demonstrate preliminary efficacy. Scheduled rumination time shows moderate to large effects. The use of a small, non-treatment seeking sample was the primary limitation.

Behavioral parenting interventions have been shown to decrease early childhood behavior problems by improving parenting skills. Few studies have examined the impact of therapist coaching statements on parenting skill acquisition, especially among ethnic minority families and non-English-speaking families. In this study, we examined therapists' use of responsive and directive coaching statements during the first coaching session in a brief parenting intervention, the Infant Behavior Program (IBP), on changes in parenting skill acquisition. Participants were 24 mothers of 12- to 15-month-olds, with elevated levels of behavioral problems from primarily Latinx and low-income backgrounds. Mothers who heard more responsive coaching from their therapist showed greater increases in positive parenting skills. Spanish-speaking therapists used fewer responsive coaching statements and more commands, however, language spoken did not moderate the effect of these statements on changes in parenting skills. Responsive coaching statements in English and Spanish had a positive impact on parenting skill acquisition.

Body-focused repetitive behaviors (BFRBs) include skin picking, trichotillomania, nail biting and cavitadaxia/lip-cheek biting, among other behaviors. For the first time, we compared three different self-help techniques aimed at reducing BFRBs. We explored the acceptance and preliminary efficacy of the approaches and whether the techniques exerted differential effects depending on BFRB-type.A total of 113 participants with at least one BFRB were randomly allocated to either habit reversal training (HRT; active elements: awareness and competing response training), decoupling (DC) or decoupling in sensu (DC-is). Reassessment was conducted 4 weeks later. The Generic Body-Focused Repetitive Behavior Scale (GBS) served as the primary outcome. The completion rate was best for DC-is (68.6%) as compared to HRT (57.1%) and DC (53.5%). A total of 34.8% of completers in the DC group showed an improvement of at least 35% on the GBS compared to 10.0% in the HRT and 23.3% in the DC-is group. In accordance with previous work, moderator analyses showed that improvement under DC is best for non-skin-pickers. A dose-effect relationship emerged, particularly for HRT. Subjective appraisal ratings were more favorable for DC-is and HRT than for DC. With respect to completion rate, subjective appraisal and symptom improvement, DC-is yielded consistently satisfactory results, whereas HRT showed good subjective but rather poor objective improvement. Those who performed DC, especially non-skin-pickers, showed good improvement but overall completion and subjective efficacy were low. Future studies should investigate whether the three techniques exert add-on effects when combined and whether demonstration via new media (e.g., video) will augment comprehensibility and thus efficacy of the techniques.

Exposure-based therapies are the gold standard treatment for anxiety disorders, and recent advancements in basic and clinical research point to the need to update the implementation of exposure. Recent research has highlighted the importance of transdiagnostic factors such as anxiety sensitivity (AS), or fear of anxiety-related sensations. Elevated AS is common among all anxiety disorders and contains three dimensions, or expectancies, that can be used to guide treatment. Recently, treatments directly targeting AS have shown potential in reducing symptoms of anxiety. In addition, inhibitory learning theory (ILT) provides an alternative explanation of exposure processes based on basic learning research. ILT extends the current framework by accounting for renewal of fear, which is important given the substantial number of individuals who experience a return of symptoms following treatment. The current paper will provide an overview of ILT and discuss several ILT techniques that can be used to target AS. These two converging bodies of research hold strong potential for optimizing treatment for anxiety.

Functional analyses are often conducted by behavior analysts to understand the environmental variables contributing to an individual's problem behavior to better inform treatment implementation. While functional analyses are integral for designing function-based interventions, they often arrange contingencies to evoke and reinforce dangerous problem behavior. In Study 1 we reviewed 22 functional analyses with open-contingency classes including non-dangerous topographies of problem behavior and we found that participants were more likely to exhibit the non-dangerous behavior in 82% of the applications. We then conducted a single-subject comparison of closed and open-contingency classes with four additional participants in Study 2. Our results suggest that the functional analyses with the open-contingency class reduced the likelihood of observing dangerous problem behavior.

The Color Wheel System (CWS) is a class-wide, rule-based, behavior management strategy that incorporates multiple sets of classroom rules to provide specific behavioral expectations for different classroom activities. This study used the CWS within three inclusion classrooms to evaluate improvements of classroom behavior for students with disabilities. A multiple-baseline design across classrooms evaluated the effects of the CWS on on-task behavior for three students with identified disabilities in each classroom. Momentary time-sampling was used to record on-task behavior, which was operationally defined as eyes on teacher or work or following teacher instructions. Visual analysis of time-series graphs and nonoverlap of all pairs (NAP) measures suggested the CWS caused immediate, large, and sustained increases in on-task behavior for students with disabilities when data are aggregated by classroom. However, individual changes in on-task behavior were variable across students. Implications for using the CWS as part of a class-wide behavioral prevention program and directions for future research are discussed.

The current text deals with the assessment of consistency of data features from experimentally similar phases and consistency of effects in single-case experimental designs. Although consistency is frequently mentioned as a critical feature, few quantifications have been proposed so far: namely, under the acronyms CONDAP (consistency of data patterns in similar phases) and CONEFF (consistency of effects). Whereas CONDAP allows assessing the consistency of data patterns, the proposals made here focus on the consistency of data features such as level, trend, and variability, as represented by summary measures (mean, ordinary least squares slope, and standard deviation, respectively). The assessment of consistency of effect is also made in terms of these three data features, while also including the study of the consistency of an immediate effect (if expected). The summary measures are represented as points on a modified Brinley plot and their similarity is assessed via quantifications of distance. Both absolute and relative measures of consistency are proposed: the former expressed in the same measurement units as the outcome variable and the latter as a percentage. Illustrations with real data sets (multiple baseline, ABAB, and alternating treatments designs) show the wide applicability of the proposals. We developed a user-friendly website to offer both the graphical representations and the quantifications.

Despite the efficacy of exposure for childhood anxiety disorders (CADs), dissemination has been unsuccessful. The current study examined community-therapist response to a brief (90-minutes) training in technology-assisted exposure therapy for CADs. The results indicated that therapists found the training in the therapy approach and technology acceptable, despite endorsing mainly non-exposure-based practice prior to the training. Training also increased positive beliefs about exposure, t (23) = 4.32, p < .000, that persisted 6 months later, t (23) = 4.56, p < .000. In addition, the number of therapists reporting an intention to implement exposure increased substantially from baseline (41.7%) to post-training (83.3%), with many therapists (70.8%) reporting use of exposure within the 6 months following training. However, automatically recorded data indicated little use of the technology. Results suggest that a dissemination message focusing on exposure is acceptable and has the potential to increase the use of this central treatment component.
