A psychological intervention reduces doping likelihood in British and Greek athletes: A cluster randomized controlled trial

BackgroundCurrent attempts to prevent doping through deterrence and education have had limited success and have been constrained to one country. Targeting psychological variables that have been empirically associated with doping likelihood, intention, or behaviour may help in developing interventions that are effective in preventing doping in sport.ObjectivesGuided by social cognitive theory and empirical research, the main purpose of this research was to develop an anti-doping intervention that targets three psychological variables (i.e., anticipated guilt, moral disengagement, and self-regulatory efficacy) and determine whether it is more effective than an educational intervention in reducing doping likelihood in British and Greek athletes.MethodEligible participants were identified via a screening survey administered to 934 athletes in the United Kingdom and Greece. A total of 19 sport clubs (208 athletes) across the two countries were randomly assigned to either the psychological or the educational intervention. Each intervention consisted of six 1-h sessions delivered to small groups of athletes over 6–8 weeks. Athletes completed measures of doping likelihood, anticipated guilt, moral disengagement, and self-regulatory efficacy pre and postintervention and at a 2-month follow-up.ResultsA multilevel piecewise growth model was used to examine changes in study outcomes. Analysis showed that the psychological intervention was more effective than the educational intervention in reducing doping likelihood from pre to post, but the effects of the two interventions were similar at follow-up. These effects were not affected by country. Both interventions reduced moral disengagement from pre to post, and these effects were maintained at follow-up. The psychological intervention was also more effective than the educational intervention in increasing anticipated guilt from pre to follow-up.ConclusionsTargeting psychological variables in anti-doping interventions should aid our efforts to prevent doping in sport.     

Proposing an ontological shift from intervention to intravention in sport and exercise psychology

Intervention research entails the measurement of change in a situation or individual after a modification has been imposed. In sport and exercise psychology, interventions have been implemented in a variety of situations (e.g., performance, doping, physical activity, mental health) for a variety of individuals (e.g., athletes, coaches, sedentary people). Despite their widespread use, accruing evidence indicates that interventions in sport and exercise psychology have had less than anticipated success in instigating change. While some scholars have pointed to the need to confront the methodological challenges of intervention implementation, others have called for the creation of viable alternative forms of inquiry that can complement intervention research. The purpose of the present article is to propose an ontological shift from intervention to intravention in sport and exercise psychology. This shift is undertaken through the deployment of Barad’s (2007) agential realist ontology. The paper is divided into six sections. First, the concept of interaction is situated as it forms the basis for how interventions are conducted. Second, the Baradian ontology of agential realism is explained, along with key concepts. Third, intravention is positioned in relation to five guiding principles that delineate the progression for conducting intravention inquiries. Fourth, alternate meanings are proposed for behaviour, change, and knowledge. Fifth, examples are provided as to how intravention inquiries can be deployed in sport and exercise psychology. Sixth, concluding thoughts are offered. As an ontological becoming of interventions, intraventions are situated as open-ended approaches to inquiry that can help researchers derive alternate understandings of existence and can take the psychology of sport and exercise in exciting and affirmative directions.     

Let's hang up and try again: Lessons learned from a social support intervention

Conclusion Theorists and researchers have spent some 15 years trying to better understand social support. A great deal of progress has been made in the assessment of support resources, behavior, and appraisals, in conceptualizing the support process, and in understanding how support might influence well-being. Community psychologists, in particular, have sought this knowledge as a basis for social intervention. The point has been reached where research and theory, though still incomplete, can inform intervention. Indeed, intervention programs are likely to make a unique contribution to our understanding.Yet, if anything has been learned, it is that the social support process is far more complex than initially thought, as is its relationship to well-being. It is essential that support interventions reflect that complexity. The greatest threat is not that powerful and effective support interventions will prove impossible to develop and implement, but that we may become disillusioned by misunderstanding our failures.     

Initial development and evaluation of the student intervention matching (SIM) form

There is currently a large gap in both research and practice between student identification practices for those at-risk (i.e., universal screening, teacher referral, or extant data as early identification methods) and the selection of appropriate Tier 2 interventions for social, emotional, and behavioral concerns. The purpose of this study was to develop and test the treatment validity of the Student Intervention Matching (SIM) Form, an intervention matching protocol designed for use at Tier 2. To this end, single-case design methodology was employed to systematically evaluate outcomes associated with use of the SIM Form in the intervention selection process. Participants included eight elementary-age students arranged in sets of four student dyads. A multiple baseline design was used in order to examine the relative effectiveness of matched interventions according to the SIM Form, and mismatched interventions according to the SIM Form. Results indicated that interventions matched using the SIM Form were functionally related to improved student outcomes across a variety of dependent variables when compared to mismatched phases. Implications for practice and future research are discussed.     

The intervention selection bias: an underrecognized confound in intervention research

Selection bias can be the most important threat to internal validity in intervention research, but is often insufficiently recognized and controlled. The bias is illustrated in research on parental interventions (punishment, homework assistance); medical interventions (hospitalization); and psychological interventions for suicide risk, sex offending, and juvenile delinquency. The intervention selection bias is most adequately controlled in randomized studies or strong quasi-experimental designs, although recent statistical innovations can enhance weaker designs. The most important points are to increase awareness of the intervention selection bias and to systematically evaluate plausible alternative explanations of data before making causal conclusions.     

A review of functional assessment use in data-based intervention studies

We reviewed the extent and variety of functional assessment procedures used in behavioral intervention studies. The contents of six research journals dating from 1986 to 1992 were searched for articles describing single-subject intervention studies that targeted problematic social behaviors. Articles meeting this initial criteria were examined to determine if a functional assessment was conducted. If so, the various procedures comprising the functional assessment, types of interventions conducted, and demographic characteristics of study participants were recorded for each study. Results are compared to similar reviews of research dating from 1980–1985. Potential reasons for the paucity of studies incorporating functional assessment procedures are discussed. Finally, directions for future research and applied practice are provided.     

Postdisaster psychological intervention since 9/11

A wealth of research and experience after 9/11 has led to the development of evidence-based and evidence-informed guidelines and strategies to support the design and implementation of public mental health programs after terrorism and disaster. This article reviews advances that have been made in a variety of areas, including development of improved metrics and methodologies for conducting needs assessment, screening, surveillance, and program evaluation; clarification of risk and resilience factors as these relate to varying outcome trajectories for survivors and inform interventions; development and implementation of evidence-based and evidence-informed early, midterm, and late interventions for children, adults, and families; adaptation of interventions for cultural, ethnic, and minority groups; improvement in strategies to expand access to postdisaster mental health services; and enhancement of training methods and platforms for workforce development among psychologists, paraprofessionals, and other disaster responders. Continuing improvement of psychologists' national capacity to respond to catastrophic events will require more systematic research to strengthen the evidence base for postdisaster screening and interventions and effective methods and platforms for training. Policy decisions are clearly needed that enhance federal funding to increase availability and access to services, especially for longer term care. Traumatic bereavement represents a critical area for future research, as much needs to be done to clarify issues related to reactions and adaptation to a traumatic death.     

Theoretical and methodological directions in mindset intervention research

Growth mindset interventions directed at students aim to change students' beliefs about the malleability of ability. These interventions have had mixed results, with some showing impressive findings (e.g., improving grades and persistence in science and closing performance gaps), while other implementations have shown null findings. This heterogeneity suggests that growth mindset interventions should not be viewed as a sole solution for improving educational outcomes for students and that further research is needed to identify the contextual factors that influence their effectiveness. We propose new theoretical directions in mindset research that adopts an anti-deficit model and moves away from focusing exclusively on students and their belief systems. Instead, we encourage a new wave of mindset research that considers the institutional, cultural, and contextual environment that either corroborates or negates students' mindset beliefs. We propose a new approach to mindset research that emphasizes innovative approaches to better understand the conditions under which mindset interventions are effective.     

Using the Performance Diagnostic Checklist–Human Services to identify an indicated intervention to decrease employee tardiness

We assessed and reduced the tardiness of 4 direct‐care staff employed at a school that provides educational services to children with autism. The Performance Diagnostic Checklist – Human Services was administered to participants and their supervisors to identify one or more indicated interventions. Relative to baseline, tardiness was lower during intervention. The most effective intervention included task clarification, a problem‐solving discussion, tokens exchangeable for back‐up reinforcers, and weekly graphic feedback. Moreover, participants reported that the intervention components, particularly praise and a token, had high acceptability.     

National Ambulatory Medical Care Survey: Tobacco intervention practices in outpatient clinics

Tobacco use remains the leading cause of preventable death. The outpatient medical clinic represents an important venue for delivering evidence-based interventions to large numbers of tobacco users. Extensive evidence supports the effectiveness of brief interventions. In a retrospective database analysis of 11,827 adult patients captured in the 2005 National Ambulatory Medical Care Survey (of which 2,420 were tobacco users), we examined the degree to which a variety of patient demographic, clinical and physician-related variables predict the delivery of tobacco counseling during a routine outpatient visit in primary care settings. In 2005, 21.7% of identified tobacco users received a tobacco intervention during their visit. The probability of receiving an intervention differed by gender, geographic region and source of payment. Individuals presenting with tobacco-related health conditions were more likely to receive an intervention. Most physicians classified as specialists were less likely to intervene. The provision of tobacco intervention services appears to be increasing at a modest rate, but remains well below desirable levels. It is a priority that brief interventions be routinely implemented to reduce the societal burden of tobacco use. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Suicide intervention trainees' knowledge of myths about suicide

The responses of 70 trainees in suicide intervention to 10 Suicide Opinion Questionnaire items were evaluated for accuracy of their knowledge about suicide myths. Participants were Canadian adults (62 women, 8 men, M (age) = 35 yr.) representing a wide variety of occupations and educational backgrounds. Analysis indicated knowledge for most items was high but less accurate for items concerning the most common method of suicide and suicide risk across the lifespan. Those trained in suicide intervention were more knowledgeable on four items than those awaiting training; they more frequently knew that most suicides are not triggered by an argument with a spouse, people who are depressed are more likely to commit suicide, a person whose parent has committed suicide is at greater risk for suicide, and that shooting is the most common method of suicide in Canada.     

助推手卫生的行为干预策略

保持手卫生是感染防控的重要策略,但是如何提高其依从性成为预防传染性疾病和减少医疗机构获得性感染的一大挑战。以行为科学为基础的手卫生助推干预以更“隐性”的方式将洗手转变为一种可自动触发的行为习惯,弥补了以知识分享和健康宣教为主的传统手卫生干预策略的诸多局限性。基于影响机制的不同,手卫生助推干预策略可分为提供决策信息、优化决策选项、影响决策结构、提醒决策方向4个大类的框架体系。多模式助推策略的有效性也已在实践中得到印证,但目前还非常缺乏在中国社会文化情境下开展的助推洗手行为的干预研究,今后可尝试基于行为科学理论有针对性地在医院、学校和社区等公共场所开展此类干预研究和实践,为感染防控、疾病预防和改善公共健康做出相应的贡献。     

A cluster randomized controlled trial of brief follow-up practice sessions on intervention maintenance

Despite considerable knowledge of the factors that influence initial intervention response, little is known about how to sustain successful intervention response over time. The current study examined spring literacy outcomes for kindergarten (n = 177), second (n = 149), and third grade students (n = 204) who successfully exited an evidence-based tutoring program during the fall semester. Successful responders in kindergarten, second, and third grade were randomly assigned by school to receive either no follow-up support or access to a once-weekly oral practice session. Results were mixed across grades and outcomes, but in kindergarten and third grade, treatment corresponded to an approximately 15% increased likelihood of meeting year-end benchmarks on targeted literacy skills. Findings are discussed in the context of suggestions for higher-quality longitudinal research designs of educational interventions.     

The emerging relationship of psychology and the Internet: proposed guidelines for conducting Internet intervention research

The Internet is rapidly developing into an important medium of communication in modern society, and both psychological research and therapeutic interventions are being increasingly conducted using this new communication medium. As therapeutic interventions using the Internet are becoming more prevalent, it is becoming increasingly important to conduct research on psychotherapeutic Internet interventions to assist in the development of an appropriate standard of practice regarding interventions using this new medium. In this article, we examine the Internet and the current psychological uses which are being initiated using this medium. Ethical concerns related to the psychological use of the Internet are discussed, and guidelines are proposed for the conduct of Internet intervention research.     

Extensions of a versatile randomization test for assessing single-case intervention effects

The purpose of the present study was to investigate the statistical properties of two extensions of the Levin-Wampold (1999) single-case simultaneous start-point model's comparative effectiveness randomization test. The two extensions were (a) adapting the test to situations where there are more than two different intervention conditions and (b) examining the test's performance in classroom-based intervention situations, where the number of time periods (and associated outcome observations) is much smaller than in the contexts for which the test was originally developed. Various Monte Carlo sampling situations were investigated, including from one to five participant blocks per condition and differing numbers of time periods, potential intervention start points, degrees of within-phase autocorrelation, and effect sizes. For all situations, it was found that the Type I error probability of the randomization test was maintained at an acceptable level. With a few notable exceptions, respectable power was observed only in situations where the numbers of observations and potential intervention start points were relatively large, effect sizes were large, and the degree of within-phase autocorrelation was relatively low. It was concluded that the comparative effectiveness randomization test, with its desirable internal validity and statistical-conclusion validity features, is a versatile analytic tool that can be incorporated into a variety of single-case school psychology intervention research situations.     

A quantitative psychometric evaluation of an intervention for poor dietary variety in children with a feeding problem of clinical significance

Few studies have been published that offer a quantitative evaluation of interventions for feeding problems of clinical significance. Twenty‐four children referred to the service for clinically significant feeding problems were administered the Behavioral Pediatric Feeding Assessment Scale (BPFAS; W. Crist & A. Napier‐Phillips, 2001) and the Child Feeding Assessment Questionnaire (CFAQ; G. Harris & I.W. Booth, 1992) before and after a duel targeted 16‐week therapeutic intervention to improve dietary variety. Dietary variety was assessed through a food diary where only items that were accepted on more than one occasion were deemed to be part of the child's habitual diet. Results indicated that all subscales of the BPFAS and the CFAQ were responsive to the intervention, with scores falling from those of clinical significance to those more representative of non‐feeding‐problem children. Regression analysis indicated that children's problem scores on the BPFAS predicted 15% of the variance in increased dietary variety following the intervention. The outcome of this evaluation indicated that improving dietary variety in children with clinically significant feeding problems is challenging. With the right approach, however, large improvements can be observed relatively quickly.     

Meta-Analysis of Single-Case Design Research on Self-Regulatory Interventions for Academic Performance

The current study examined the effects of self-regulatory interventions on reading, writing, and math by conducting a meta-analysis of single-case design research. Self-regulatory interventions have promise as an effective approach that is both minimally invasive and involves minimal resources. Effects of the interventions were analyzed by academic subject, grade, educational placement, and the number of sessions. Results indicated that self-regulatory strategies showed promise in addressing academic issues in the areas of reading, writing, and math regardless of age, grade, educational placement, and intervention length.     

Assessing the impact of healthy work organization intervention

This research evaluates a healthy work organization intervention implemented in a retail setting. Using a participatory process, employee teams in 11 intervention stores developed customized plans for improving work organization at their sites. Ten comparable stores served as controls. Employee surveys were administered prior to the intervention and twice again at 12‐month intervals. Business results were compiled monthly for each store. The baseline data were used by the teams to identify needs and establish action priorities for their stores. Most study outcomes declined across time for all stores, due primarily to internal corporate events and a generally adverse economic environment. However, the intervention process appeared to buffer some of these declines; intervention stores fared better in terms of selected aspects of organizational climate and psychological work adjustment. Intervention stores also performed better than controls on general indices of perceived health and safety and two of the four business outcomes: employee turnover and sales per labour hour. These results are discussed in terms of the challenges involved in evaluating organizational‐level interventions in work settings.
