Examines reliability issues in the large-scale assessment of speech communication through authentic techniques, used recently in Saskatchewan. Performance-based approaches enable educators to evaluate the integrated, interpersonal communication skills of large student populations, thereby modeling best professional practice.

Analyzed relationships between child-care experience and preschoolers' attachment. Found that maternal sensitivity was the strongest predictor of preschoolers' attachment. When maternal sensitivity was low, more hours per week in child care at 15 months somewhat increased the risk of the insecure-ambivalent classification at 36 months. Found…

The current studies explore causal models of heart attack and depression generated from American healers whom use distinct explanatory frameworks. Causal chains leading to two illnesses, heart attack and depression, were elicited from participant groups: registered nurses (RNs), energy healers, RN energy healers, and undergraduates. The…

We conducted a reliability generalization meta-analysis to examine the internal consistency of Dyadic Adjustment Scale (DAS; Spanier, 1976) scores across 91 published studies with 128 samples and 25,035 participants. The DAS was found to produce total and Dyadic cohesion, Consensus, and Satisfaction scores of acceptable internal consistency,…

Identification of children with developmental disabilities is the first critical step in providing early intervention services. Currently, only 20% of Taiwanese children who could potentially benefit from early intervention have been identified.

This study provided initial validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS). Data were collected from intercollegiate men's (n = 8) and women's (n = 13) soccer and women's ice hockey teams (n = 11). The total number of athletes was 585. Within teams, a multidimensional…

Not all policy questions can be addressed by social experiments. Nonexperimental evaluation methods provide an alternative to experimental designs but their results depend on untestable assumptions. This paper presents evidence on the reliability of propensity score matching (PSM), which estimates treatment effects under the assumption of…

Preffi 2.0 is an evidence-based Dutch quality assessment instrument for health promotion interventions. It is mainly intended for both planning and assessing one's own projects but can also be used to assess other people's projects (external use).

The purpose of this study was to determine and compare the reliability of 3 dimension reaction forces and impulses in walking with 3 different heel shoe conditions. These results suggest that changing the height of the heels affects mainly the reliability of the ground reaction force and impulse measures on the medial and lateral dimension and not…

The purpose of this study was to examine the psychometric properties of the Group Environment Questionnaire (GEQ) adapted to the Greek language. The sample consisted of 586 male and female volleyball players of elite and regional level status. Data were analysed from three time points of a competitive season.
