Meta- and statistical analysis of single-case intervention research data: Quantitative gifts and a wish list

In this commentary, we add to the spirit of the articles appearing in the special series devoted to meta- and statistical analysis of single-case intervention-design data. Following a brief discussion of historical factors leading to our initial involvement in statistical analysis of such data, we discuss: (a) the value added by including statistical-analysis recommendations in the What Works Clearinghouse Standards for single-case intervention designs; (b) the importance of visual analysis in single-case intervention research, along with the distinctive role that could be played by single-case effect-size measures; and (c) the elevated internal validity and statistical-conclusion validity afforded by the incorporation of various forms of randomization into basic single-case design structures. For the future, we envision more widespread application of quantitative analyses, as critical adjuncts to visual analysis, in both primary single-case intervention research studies and literature reviews in the behavioral, educational, and health sciences.     

Feasibility of a Community Intervention for the Prevention of Suicide and Alcohol Abuse with Yup’ik Alaska Native Youth: The Elluam Tungiinun and Yupiucimta Asvairtuumallerkaa Studies

The Elluam Tungiinun and Yupiucimta Asvairtuumallerkaa studies evaluated the feasibility of a community intervention to prevent suicide and alcohol abuse among rural Yup’ik Alaska Native youth in two remote communities. The intervention originated in an Indigenous model of protection, and its development used a community based participatory research process. Feasibility assessment aimed to assess the extent to which (1) the intervention could be implemented in rural Alaska Native communities, and (2) the intervention was capable of producing measurable effects. Scales maximally sensitive to change were derived from earlier measurement work, and the study contrasted implementation process and outcomes across the two communities. In one community, medium dose response effects (d = .30–.50), with dose defined as number of intervention activities attended, were observed in the growth of intermediate protective factors and ultimate variables. In the other community, medium dose effects were observed for one intermediate protective factor variable, and small dose effects were observed in ultimate variables. Differences across communities in resources supporting intervention explain these contrasting outcomes. Results suggest implementation in these rural Alaska settings is feasible when sufficient resources are available to sustain high levels of local commitment. In such cases, measureable effects are sufficient to warrant a prevention trial.     

More than meets the eye: a consideration of the influence of a counsellor's visual impairment upon his therapeutic relationships

Other than through personal reflection and anecdotal evidence, I have had little opportunity to explore the influence of my visual impairment upon my therapeutic relationships. In order to address this, I conducted three research conversations with former clients (participants), each of whom had expressed an interest in participating in the research. Potential participants also had to meet the inclusion criteria for the research and provide informed consent prior to their participation. Research conversations were conducted between March and July 2009 and were analysed qualitatively, using a method informed by Moustakas's heuristic inquiry. Participants demonstrated idiosyncratic responses to my visual impairment; their perception of their responses to my visual impairment sometimes differed from mine. Feelings identified included uncertainty, disappointment and relief. My visual impairment appeared to influence the therapeutic relationship in a variety of ways, including resonance with the inner world significance of disability to the participant and interaction with my personal process. While not the therapeutic agent, my visual impairment had the potential to act as a catalyst in therapeutic change. The potential for me to either under-estimate or over-estimate the significance of my visual impairment highlights the need for continued self-awareness and the maintenance of an open and non-defensive attitude.     

Anticipating action effects recruits audiovisual movement representations in the ventral premotor cortex

When table tennis players anticipate the course of the ball while preparing their motor responses, they not only observe their opponents striking the ball but also listen to events such as the sound of racket–ball contact. Because visual stimuli can be detected more easily when accompanied by a sound, we assumed that complementary sensory audiovisual information would influence the anticipation of biological motion, especially when the racket–ball contact is not presented visually, but has to be inferred from continuous movement kinematics and an abrupt sound. Twenty-six observers were examined with fMRI while watching point-light displays (PLDs) of an opposing table tennis player. Their task was to anticipate the resultant ball flight. The sound was presented complementary to the veracious event or at a deviant time point in its kinematics.Results showed that participants performed best in the complementary condition. Using a region-of-interest approach, fMRI data showed that complementary audiovisual stimulation elicited higher activation in the left temporo-occipital middle temporal gyrus (MTGto), the left primary motor cortex, and the right anterior intraparietal sulcus (aIPS). Both hemispheres also revealed higher activation in the ventral premotor cortex (vPMC) and the pars opercularis of the inferior frontal gyrus (BA 44). Ranking the behavioral effect of complementary versus conflicting audiovisual information over participants revealed an association between the complementary information and higher activation in the right vPMC. We conclude that the recruitment of movement representations in the auditory and visual modalities in the vPMC can be influenced by task-relevant cross-modal audiovisual interaction.

Practice‐based research networks: Origins,overview, obstacles,and opportunities

Aims: This article focuses on the historical origins of Practice‐based Research Networks (PbRNs), particularly in the UK, and provides an overview of exemplar networks, together with a consideration of the obstacles and opportunities of such networks. Method: A selective narrative review was carried out relating to the origins of PbRNs together with a selective systematic review using the SCOPUS database to consider landmark articles in this field. Results: A historical account is provided with the origins of PbRNs deriving from pioneer GPs working alone, with their ideals then becoming embedded in family practice. Key articles are presented and also consideration given to the threats to their survival. Conceptual and developmental models of PbRNs are presented that reflect the variety of networks but also common hallmarks. Finally, the opportunities are summarised that PbRNs offer for providing a vehicle for research that is linked more closely to communities of practitioners, people, and patients. Conclusions: PbRNs provide the opportunities for including practitioners in the research effort by being part of a community. Results will have direct relevance to their practice and advances in data analysis provide more valid means of analysing data. But there are also continuing threats due to lack of infrastructure funding and a gap between PbRN activity and trials methodology that needs to be addressed.     

Therapist orientation,supervisor match,and therapeutic interventions: Implications for session quality in a psychotherapy training PRN

Background: Theoretical orientation is a multifaceted construct that is integral to the process of psychotherapy and psychotherapy training. While some research has been conducted on personal identification with particular schools of psychotherapy, techniques used in psychotherapy sessions, and match between trainees and supervisors in training, there is insufficient information regarding how these may interact with one another. Aim: This study, conducted in a practice research network of trainee therapists, was designed to test whether these variables may be related to one another in predicting session quality. Method: The sample comprised 328 sessions from 26 clients and 11 therapists, with the clients completing session quality measures and therapists completing measures of technique immediately post‐session. Results: Using multilevel linear modelling, the data showed varied results. For behavioural therapy and person‐centred therapy, techniques and orientation were unrelated to session quality in the sample. However, process‐experiential, psychodynamic, and cognitive therapy techniques were all involved in interactions with therapist and/or supervisor orientations. Conclusions: These results suggest that the impact of specific psychotherapy techniques sometimes depends on the orientation of the therapist and/or supervisor. For instance, sessions high in cognitive therapy techniques were only associated with positive outcome when both the therapist and supervisor were highly cognitively oriented. Though preliminary, these results suggest that orientation may be an important variable to consider in training and supervision, especially in the context of other variables.     

Conducting Health Disparities Research with Criminal Justice Populations: Examining Research,Ethics, and Participation

This study explored the challenges of informed consent and understanding of the research process among Black and Latino men under community supervision (e.g., parole and/or probation). Between February and October 2012, we conducted cognitive face-to-face interviews using open-ended questions on the significant areas of research participation (i.e., the informed consent process, confidentiality, compensation, what is meant by human subject and clinical trials) among 259 men aged 35 to 67 under community supervision in Bronx, New York. Content analysis of the open-ended questions revealed limited knowledge concerning the understanding of research participation. The study participants appeared to generally understand concepts such as compensation after research participation and confidentiality. Participants demonstrated a lack of understanding of certain aspects of the research process—informed consent, human subject, Institutional Review Board, and clinical trials. These findings are informative to researchers conducting studies with criminal justice populations and Institutional Review Boards reviewing research studies.
