Technical standards and performance standards in the pursuit of quality

The concept of standards lacks clarity because it is applied both to concrete specifications and to the assessment of quality. Confusion is reduced by introducing the notion of interchange expectancy. distinguishing transfer, coupling, and market success as components. Transfer expectancy depends upon the products to be transported or exchanged, but when there is a need to estimate transfer expectancy, a combination of technical standards and performance standards must be applied. Though performance standards are intended to produce quality, the quality of the instrumentation to measure performance standards is often neglected. The development of high-quality performance standards first requires the delineation of the relevant dimensions of performance quality. The process of giving precision to performance standards may lead to the emergence of more acceptable technical standards. To illustrate some of these points, data is presented from the CONDUIT system for quality evaluation of computer-based curriculum materials. The performance quality of these products includes the dimension of transfer expectancy, as well as educational and scientific merit. Increased specification and impact of technical standards may provide greater incentives to authors and hence lead to the invention of products which have higher educational and scientific quality.     

Functional communication training: From efficacy to effectiveness

Functional communication training (FCT; Carr & Durand, 1985) is a common function‐based treatment in which an alternative form of communication is taught to reduce problem behavior. FCT has been shown to result in substantial reductions of a variety of topographically and functionally different types of problem behavior in children and adults (efficacy). The extent to which these reductions maintain in relevant contexts and result in meaningful changes in the lives of those impacted (effectiveness) is the focus of this paper. This review evaluates the degree to which FCT has been established as an evidence‐based practice in psychology (EBPP) according to the definition set out by the American Psychological Association's 2005 Presidential Task Force on Evidence‐Based Practice. Our review finds overwhelming evidence in support of FCT as an efficacious treatment but highlights significant limitations in support of its effectiveness. In order to also be recognized as an EBPP, future research on FCT will need to focus more closely on issues related to home, school, and community application, feasibility, consumer satisfaction, and more general and global changes for the individual.

Interpersonal Psychotherapy—Adolescent Skills Training With Youth From Asian American and Immigrant Families: Cultural Considerations and Intervention Process

Although research has identified effective evidence-based depression prevention interventions for diverse youth, little is known about how the intervention process unfolds with immigrant family youth. This study utilized a qualitative approach to explore cultural and clinical differences in the implementation of Interpersonal Psychotherapy–Adolescent Skills Training (IPT-AST) in two schools, one serving youth from primarily immigrant, Asian American families and the second, youth from mostly nonimmigrant, non-Hispanic White families. A total of 131 IPT–AST sessions were audio recorded, transcribed, and coded for presence and patterns of cultural and clinical constructs. Results revealed that sessions with immigrant family youth were more likely to contain discussions of interpersonal problems characterized by estrangement, goals of spending time together with important others, mentions of emotion suppression and academic achievement expectations, conversations about acculturation, differences in value orientation, and discomfort with implementing new intervention skills. Dialogue from interventionist and youth exchanges is presented to illustrate how these themes emerged and were addressed by interventionists in a culturally responsive manner. The study highlights how IPT–AST with immigrant family and Asian American youth may unfold differently compared to youth from nonimmigrant families. Implications of findings for providers are discussed.     

Adaptive spatial working memory assessments for aging pet dogs

Assessments for spatial working memory (SWM) in pet dogs that can detect age-related cognitive deficits in a single session may aid in diagnosing canine dementia and may facilitate translational research on Alzheimer’s disease in humans. Adaptive testing procedures are widely used in single-session assessments for humans with diverse cognitive abilities. In this study, we designed and deployed two up-down staircase assessments for SWM in which 26 pet dogs were required to recall the location of a treat hidden behind one of two identical boxes following delays of variable length. In the first experiment, performance tended to decline with age but few dogs completed the test (n?=?10). However, all of the dogs that participated in the second experiment (n?=?24) completed the assessment and provided reliable evidence of learning and retaining the task. Delay length and age significantly predicted performance supporting the validity of this assessment. The relationships between age and performance were described by inverted U-shaped functions as both old and young dogs displayed deficits in weighted cumulative-scores and trial-by-trial performance. Thus, SWM in pet dogs may develop until midlife and decline thereafter. Exploratory analyses of non-mnemonic fixation strategies, sustained engagement, inhibitory control, and potential improvements for future SWM assessments which adopt this paradigm are also discussed.

     

Social competence in early childhood: An empirical validation of the SOCIAL model

Social skills are the basis of human interactions and functioning in society. Social competence (SC) is thought to evolve gradually during childhood and adolescence via the interplay of multiple factors. In particular, the early years of life are marked by the emergence of basic social abilities and constitute the foundation for successful social development. The biopsychosocial SOcio-Cognitive Integration of Abilities modeL (SOCIAL) posits that internal (child-based), external (environment), and cognitive factors are critical to SC in the context of normal brain maturation; but this has yet to be shown empirically and comprehensively. This study tested the SOCIAL model in a sample of typically developing preschool children. Parents of 103 children (M = 67.59 months, SD = 11.65) completed questionnaires and children underwent neuropsychological assessment of executive functioning (EF), communication skills and social cognition. Three-step hierarchical regression analyses (1) Internal factors, 2) External factors, 3) Cognitive factors) confirmed that each step of the regression model significantly predicted SC. In the final model, general cognitive and socio-cognitive factors significantly predicted SC above and beyond internal and external factors: children with lower temperamental negative affect and less parent-reported executive dysfunction, as well as better non-verbal communication and theory of mind had better SC. Our findings support the conceptual SOCIAL model, and highlight the importance of internal, external, and cognitive factors for SC in the preschool years. Identification of factors associated with early social development can inform both normative and clinical approaches to identifying intervention loci and optimizing SC in those at risk for maladaptive social functioning.     

When is the Wilcoxon–Mann–Whitney procedure a test of location? Implications for effect-size measures

The Wilcoxon–Mann–Whitney procedure is invariant under monotone transformations but its use as a test of location or shift is said not to be so. It tests location only under the shift model, the assumption of parallel cumulative distribution functions (cdfs). We show that infinitely many monotone transformations of the measured variable produce parallel cdfs, so long as the original cdfs intersect nowhere or everywhere. Thus there are infinitely many effect sizes measured as shifts of medians, invalidating the notion that there is one true shift parameter and thereby rendering any single estimate dubious. Measuring effect size using the probability of superiority alleviates this difficulty.
