Bayesian approach is becoming increasingly important as it provides many advantages in dealing with complex data. However, there is no well-defined model selection criterion or index in a Bayesian context. To address the challenges, new indices are needed. The goal of this study is to propose new model selection indices and to investigate their…

This paper challenges the neglect of psychotherapeutic methods in therapy research and discusses the use of methods arising directly from therapy practice to generate research data. Recent developments in therapy research culture are critiqued in order to contextualise the present contribution. The research design and methodology evolve from the…

A common reason for not participating in intimate partner violence (IPV) research is thought to be fear for one's safety. However, little is known about those who do not participate due to safety fears. To better characterize this population, we investigated correlates of being "not safe" to answer the optional IPV module in the 2006…

This study demonstrates that those who, in social surveys, misreport their voting behavior in presidential elections are, attitudinally and demographically, similar to validated voters. It also shows how error arising from such misreporting may have biased prior research on nonvoters and on the voting behavior of Blacks and young people.…

A popular theoretical account of developmental language and literacy disorders implicates poor auditory temporal processing in their etiology, but evidence from studies using behavioral measures has yielded inconsistent results. The mismatch negativity (MMN) component of the auditory event-related potential has been recommended as an alternative,…

Classical methods for detecting outliers deal with continuous variables. These methods are not readily applicable to categorical data, such as incorrect/correct scores (0/1) and ordered rating scale scores (e.g., 0,..., 4) typical of multi-item tests and questionnaires. This study proposes two definitions of outlier scores suited for categorical…

Finds that when subjects have a week to reflect on the research hypothesis, they will attempt to prove the hypothesis. Does not find, however, that increased information yields negative research results. (RL)

Three computer simulations were conducted to show that very high aggregate predictive validity coefficients can occur when the across-case variability in absolute score stability occurring in both the predictor and criterion matrices is quite small. In light of the increase in internal consistency reliability achieved by the method of aggregation…

Presented are the report and recommendations of the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research regarding the involvement of children in research, with particular emphasis on P.L. 93-348. Following an introductory section, containing definitions of terms relevant to the report, are 10…

The use of large-N group comparison research methods based on a nomothetic model is compared with idiographic methods employing single-system designs and intensive study of the individual. Limitations of the nomothetic model and advantages of the idiographic approach are presented. (SK)

To replicate the Kuehl et al. (1975) study, 151 graduate students completed the Leadership Opinion Questionnaire, Least Preferred Co-Worker (LPC) Questionnaire, FIRO-B (Functional Interpersonal Relations Orientation-Behavior), and F-Scale. Data failed to replicate earlier significant correlations between interpersonal needs as measured by the LPC…

This is a review of research relating to the attributes of portrayals which play a role in affecting aggressive behavior. The effects of portrayal can occur at any of three successive stages: acquisition, disinhibition/stimulation/arousal, performance. The older the individual, the more likely the influence is to be in all three stages of…

The purpose of this study was to determine the efficacy of induced affect as a pregroup training experience for coping with stress related to participation in an encounter group. Twenty-six subjects who volunteered to participate in an encounter group randomly were assigned to three treatment groups: Induced Affect Training plus the Encounter…

Numerous forms and meanings of validity have been developed to provide researchers with the opportunity to assess the many potential sources of ambiguity that exist in any research finding. A Validity Network Schema (VNS) developed by Brinberg & McGrath (1982) is extended and elaborated in order to describe the components of the research…

The appendix contains papers, reports, and other materials that were reviewed by the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research during its deliberations on research involving children. Entries include the following titles and authors: "Research Involving Children" (Survey Research Center); "Law…
