Irritable bowel syndrome (IBS) is a highly prevalent disorder with a significant impact on quality of life. The presence of psychological symptoms in IBS patients such as catastrophic worry and behavioral avoidance suggests the possible efficacy of cognitive behavioral interventions. Exposure-based cognitive behavioral therapy (CBT) has proven to be a promising approach but has only been investigated in a few studies and mainly via the Internet. Therefore, the aims of this study were to extend and replicate previous findings and to evaluate whether an individual, face-to-face, exposure-based CBT leads to improvement in gastrointestinal symptoms, pain catastrophizing, avoidance behavior and quality of life in IBS patients. Thirteen patients with IBS according to Rome III criteria participated in a single-case experimental study using a five-week baseline and a subsequent twelve-session intervention phase focusing on psycho-education, mindfulness and in vivo exposure. Standardized measurement of gastrointestinal symptoms, pain catastrophizing, avoidance behavior and quality of life was conducted weekly during baseline as well as intervention phase and at six-month follow-up. Results showed that over 70% of patients improved significantly on gastrointestinal symptoms, pain catastrophizing, and quality of life. Effects on avoidance behavior were modest. These results strengthen and extend earlier findings and provide further support for the efficacy of exposure-based strategies for IBS.  相似文献

Single-case research designs (SCRDs) are a vital tool for researchers and practitioners in counseling to evaluate intervention and treatment effectiveness. This content analysis reviews the application of SCRDs in counseling to highlight knowledge accrued and existing gaps in the literature. We evaluated the methodological design and reporting adherence against recommended guidelines to provide guidance for future research. We included 50 SCRDs published between 2015 and 2021 across 15 journals (42 reviewed). Content results showed several trends, strengths, and areas of improvement in counseling SCRDs. No studies completely met the What Works Clearinghouse (2022) design standards or Single-Case Reporting Guideline in Behavioural Interventions (SCRIBE) reporting standards, yet several indicators had high levels of adherence. We discuss how the experimental design process can be enhanced to improve the internal validity, ways to improve transparency in reporting SCRD results, and the importance of contextualizing SCRD methodology to the counseling field.  相似文献

Meta-analytic methods provide a way to synthesize data across treatment evaluation studies. However, these well-accepted methods are infrequent with behavior analytic studies. Multilevel models may be a promising method to meta-analyze single-case data. This technical article provides a primer for how to conduct a multilevel model with single-case designs with AB phases using data from the differential-reinforcement-of-low-rate behavior literature. We provide details, recommendations, and considerations for searching for appropriate studies, organizing the data, and conducting the analyses. All data sets are available to allow the reader to follow along with this primer. The purpose of this technical article is to minimally equip behavior analysts to complete a meta-analysis that will summarize a current state of affairs as it relates to the science of behavior analysis and its practice. Moreover, we aim to demonstrate the value of analyses of this sort for behavior analysis.  相似文献

Four dimensions (applied, analytic, general, conceptual) were selected from Baer, Wolf, and Risley's (1968) seminal article on the nature of applied behavior analysis and were monitored throughout the first 10 volumes of the Journal of Applied Behavior Analysis. Each of the experimental articles in Volumes 1 through 6 and the first half of Volumes 7 through 10 was rated on each of these dimensions. The trends showed that applied behavior analysis is becoming a more purely technical effort, with less interest in conceptual questions. We are using simpler experimental designs and are conducting fewer analogue studies. Although concern for maintenance is increasing, other forms of generality are being measured or analyzed less often. These trends are discussed in terms of a technical drift in applied behavior analysis.  相似文献

The contributions of Joseph V. Brady to behavioral pharmacology span more than 50 years and range from early studies using the Estes-Skinner (conditioned emotional response) procedure to examine drug effects and various physiological processes in experimental animals to the implementation of mobile methadone treatment services and to small group behavioral analyses in simulated space environments. This expansive range of activities is based on Brady's insight and innovative use of behavioral procedures, his spirited and unabashed enthusiasm for the discipline and its philosophical underpinnings, together with a collegiality and commitment to the experimental analysis of behavior that is both legendary and inspirational. These contributions are summarized and highlighted in this tribute that focuses primarily on Brady's contributions to behavioral pharmacology but which also acknowledges his conceptual and technical contributions spanning multiple disciplines.  相似文献

The fields of genetics and neuroscience are yielding findings useful in understanding complex behavior-environment relations. We believe that these developments in interdisciplinary basic research are of interest to applied behavior analysts because of the long history of basic findings being used by the readership of the Journal of Applied Behavior Analysis to improve everyday human activities. An awareness of contemporary developments in a range of basic research disciplines may facilitate the systematic replication of those functional relations in applied settings. In this context, we selectively review papers published in the Journal of the Experimental Analysis of Behavior and other basic research journals that relate to gene-brain-behavior relations.  相似文献

As a stage-based model of learning, the Instructional Hierarchy offers a useful heuristic for organizing research on effective instructional strategies at different levels of skill proficiency. In this paper, we summarize and highlight the unique contributions of each empirical study presented in the special issue. We describe common methodological features across the studies that likely contributed to intervention effectiveness, and present several implications for research and practice.  相似文献

There is increasing evidence to support the biological basis of mental disorders. Subsequently, understanding the neurobiological context from which mental distress arises can help counselors appropriately apply cognitive behavioral therapy and other well‐researched cognitive interventions. The purpose of this article is to describe the neurobiological context underlying the formation and treatment of posttraumatic stress disorders, a mental disorder frequently encountered by counselors, from a cognitive therapy framework.  相似文献

The National Institutes of Health established the Science of Behavior Change (SOBC) program to promote basic research on the initiation, personalization, and maintenance of health behavior change. The SOBC Resource and Coordinating Center now leads and supports activities to maximize the creativity, productivity, scientific rigor, and dissemination of the experimental medicine approach and experimental design resources. Here, we highlight those resources, including the Checklist for Investigating Mechanisms in Behavior-change Research (CLIMBR) guidelines introduced in this special section. We describe the ways in which SOBC can be applied across a range of domains and contexts, and end by considering ways to extend SOBC’s perspective and reach, so as to best promote behavior change linked with health, quality of life, and well-being.  相似文献

The effect of fines for failure to conserve water during the California drought of 1976 to 1978 was evaluated in a retrospectively arranged multiple-baseline design across three San Francisco Bay area cities. The data indicated that, on a community level, significant savings of water occurred regardless of whether fines were introduced or not. However, on an individual level, fines appeared to have an effect on private, as opposed to commercial or industrial, consumers who had received at least one fine. The limitations imposed on these conclusions by the quasi-experimental nature of the design were highlighted. Possible reasons for water conservation in the absence of fines were discussed within the framework of stimulus control. It was suggested that an area for future research should be the delineation of stimulus parameters involved in producing behavior change in entire communities.  相似文献

Are risk-takers more likely to engage in unethical behaviors? We examined the relationship between risk-taking propensity and cheating in two experimental studies. In Study 1, we examined the relationship between subjects’ risk-taking propensity and their actual self-serving dishonesty using a gambling-like task. The results suggested that risk-taking propensity, measured using a behavioral approach, was positively correlated with actual self-serving dishonest behavior. In Study 2, we measured participants’ performances using a matrices test and found that the positive correlation still held. We found that participants with high risk-taking propensity reported a lower perceived probability of being detected, which might drive their dishonest behavior.  相似文献

How do people form expectations about the future? We use amateur and expert investors' expectations about financial asset prices to study this question. Three experiments contrast the rational expectations assumption from neoclassical economics (investors forecast according to neoclassical financial theory) against two psychological theories of expectation formation—behaviorally informed expectations (investors understand empirical market anomalies and expect these anomalies to occur) and narrative expectations (investors use narrative thinking to predict future prices). Whereas neoclassical financial theory maintains that past public information cannot be used to predict future prices, participants used company performance information revealed before a base price quotation to project future price trends after that quotation (Experiment 1), contradicting rational expectations. Importantly, these projections were stronger when information concerned predictions about a company's future performance rather than actual data about its past performance, suggesting that people not only rely on financially irrelevant (but narratively relevant) information for making predictions but erroneously impose temporal order on that information. These biased predictions had downstream consequences for asset allocation choices (Experiment 2), and these choices were driven in part by affective reactions to the company performance news (Experiment 3). There were some mild effects of expertise, but overall the effects of narrative appear to be consistent across all levels of expertise studied, including professional financial analysts. We conclude by discussing the prospects for a narrative theory of choice that provide new microfoundational insights about economic behavior.  相似文献

We used a novel meta regression analysis approach to examine the effectiveness of psychological skills training and behavioral interventions in sport assessed using single-case experimental designs (SCEDs). One hundred and twenty-one papers met the inclusion criteria applied to eight database searches and key sport psychology journals. Seventy-one studies reported sufficient detail for effect sizes to be calculated for the effects of psychological skills training on psychological, behavioral, and performance variables. The unconditional mean effect size for weighted (Δ = 2.40) and unweighted (Δ = 2.83) models suggested large improvements in psychological, behavioral, and performance outcomes associated with implementing cognitive-behavioral psychological skills training and behavioral interventions with a SCED. However, meta-regression analysis revealed important heterogeneities and sources of bias within this literature. First, studies using a group-based approach reported lower effect sizes compared to studies using single-case approaches. Second, the single-case studies, (over 90 per cent the effect sizes), revealed upwardly biased effect sizes arising from: (i) positive publication bias such that studies using lower numbers of baseline observations reported larger effects, while studies using larger numbers of baseline observations reported smaller – but still substantial – effects; (ii) not adopting a multiple baseline design; and (iii) not establishing procedural reliability. We recommend that future researchers using SCED’s should consider these methodological issues.  相似文献

随着行为主义衰落和生物学技术发展,长期遭受“冷遇”的人格行为遗传学研究近些年成为颇受关注的领域,并由数量遗传学取向发展到分子遗传学取向.数量遗传学取向主张运用双生子研究、收养研究等设计来估计群体中遗传因素对人格表现型方差的贡献率,在人格特质、人格障碍、态度与偏好等人格方面做了大量研究.分子遗传学取向主张在DNA水平上用基因测定方法研究特定基因对人格表现型的影响效应,着重从多巴胺、5-羟色胺和去甲肾上腺素三种神经递质路径考察了基因与人格的关系.未来研究要强调在数量遗传设计中加入对特定基因型的直接测量,注重多学科和多范式的有效整合,扩大对健康人群积极人格品质的研究,加强基因对人格的深层作用机制研究和分子医学层面的人格干预研究.  相似文献
