Teaching undergraduates the basic properties of an estimator can be difficult. Most definitions are easy enough to comprehend, but difficulties often lie in gaining a "good feel" for these properties and why one property might be more desired as compared to another property. Simulations which involve visualization of these properties can…

The authors examined the cultural validity of Fear Survey Schedule for Children (FSSC-AM) developed by J. J. Burnham (2005) with Turkish children. The relationships between demographic variables and the level of fear were also tested. Three independent data sets were used. The first data set comprised 676 participants (321 women and 355 men) and…

The aim of the present study was to evaluate the intra- and inter-tester reliability of the movement assessment battery for children-second edition (MABC-2), ageband 2. We wanted to analyze the collected data, with adequate statistical methods, to provide relevant recommendations for physical therapists who are interpreting changes in the context…

Children are notoriously bad at delaying gratification to achieve later, greater rewards (e.g., Piaget, 1970)--and some are worse at waiting than others. Individual differences in the ability-to-wait have been attributed to self-control, in part because of evidence that long-delayers are more successful in later life (e.g., Shoda, Mischel, &…

Background: The Six-Minute Walk Test (6MWT) has been used with clinical and healthy populations to assess functional capacity and cardiovascular fitness. The aim of this study was to determine the test-retest reliability of a modified-6MWT as well as concurrent validity of walk distance with peak oxygen uptake (VO[subscript 2] peak). Method:…

Background: speechBITE (http://www.speechbite.com) is an online database established in order to help speech and language therapists gain faster access to relevant research that can used in clinical decision-making. In addition to containing more than 3000 journal references, the database also provides methodological ratings on the PEDro-P (an…

How do children evaluate complex causal events? This study investigates preschoolers' representation of "force dynamics" in causal scenes, asking whether (a) children understand how single and dual forces impact an object's movement and (b) this understanding varies across cause types (Cause, Enable, Prevent). Three-and-a half- to…

A classic topic in the fields of psychometrics and measurement has been the impact of the number of scale categories on test score reliability. This study builds on previous research by further articulating the relationship between item response theory (IRT) and classical test theory (CTT). Equations are presented for comparing the reliability and…

Assessment of human abilities and behaviors is enormously enhanced by the use of standardized assessment measures that yield norm-referenced scores. As school psychologists, they rely on quantitative findings to anchor their judgments about a child's developmental and educational functioning and to enhance our capacity to draw diagnostic…

The present study investigated the stability of scores on the WISC-IV and WAIS-IV over an approximate six-year period. Previous research using older versions of the WISC and WAIS have suggested that these scales demonstrate strong stability of scores. Since research that has compared the stability of scores between the WISC-IV and the WAIS-IV is…

The advantages of having a strong professional identity include ethical performances, promoted wellness, and increased awareness of roles and functions among individual counselors (Brott & Myers, 1999; Grimmit & Paisley, 2008; Ponton & Duba, 2009). Scholars in the counseling field have underscored the importance of unified professional…

The introduction of the Consumer Assessment of Healthcare Providers and Systems (CAHPS), a family of survey instruments designed to capture and report people's experiences obtaining health care could soon add satisfaction as a consistent dimension of quality that skilled nursing facilities (SNFs) are required to assess and report. The SNF setting…

Factor structure for the Goal Attainment Scale of Stabilization was evaluated using separate samples for exploratory factor analysis and confirmatory factor analysis. Results indicated a 25-item two-factor solution. The Goal Attainment Scale of Stabilization may be useful in identifying the extent to which adolescents in crisis meet therapeutic…

Background: In a recent article, Hallinger (2011b) reviewed 135 empirical studies that had employed the Principal Instructional Management Rating Scale (PIMRS) over the prior three decades. The author concluded that the PIMRS appeared to have attained a consistent record of yielding reliable and valid data on principal instructional leadership.…

While there are appropriate tools to progress monitor academics, there is no universally accepted tool to progress monitor social behavior. The current study proposed the development of a series of brief behavior rating scales to correspond to important social skills domains on the Social Skills Rating Scale (Gresham&Elliott, 2008) and to…
