Many states have scaled up School-Wide Positive Behavioral Interventions and Supports (SW-PBIS) with the goal of improving student behavior and academic outcomes. Although the effects of SW-PBIS on behavioral and discipline outcomes have been promising, the findings for academic achievement have been inconclusive and are often limited to…

Teacher praise is an effective strategy that decreases preschool students' disruptive behavior. It is well established that school-aged students with behavior problems receive fewer teacher praises than their peers; however, it is unclear whether these findings are consistent among preschool students. The purpose of this study was to collect…

This study investigated the use of compressed speech as a modality for assessment of the simultaneous processing function for participants with visual impairment. A 24-item compressed speech test was created using a sound editing program to randomly remove sound elements from aural stimuli, holding pitch constant, with the objective to emulate the…

The authors conducted a meta-analysis and systematic review that examined 23 studies evaluating the effectiveness of child centered play therapy (CCPT) conducted in elementary schools. Meta-analysis results were explored using a random effects model for mean difference and mean gain effect size estimates. Results revealed statistically significant…

Research using an attachment theory framework has provided evidence that parent attachment is one of the crucial determinants of psychological adjustment in adolescents, including global life satisfaction (LS). This study investigated the interrelationships among parent attachment, hope, and LS during early adolescence, including the mediation…

Criticism has been leveled against the use of statistical significance testing (SST) in many disciplines. However, the field of school psychology has been largely devoid of critiques of SST. Inspection of the primary journals in school psychology indicated numerous examples of SST with nonrandom samples and/or samples of convenience. In this…

Despite being under challenge for the past 50 years, null hypothesis significance testing (NHST) remains dominant in the scientific field for want of viable alternatives. NHST, along with its significance level "p," is inadequate for most of the uses to which it is put, a flaw that is of particular interest to educational practitioners…

The present article provides a primer on (a) effect sizes, (b) confidence intervals, and (c) confidence intervals for effect sizes. Additionally, various admonitions for reformed statistical practice are presented. For example, a very important implication of the realization that there are dozens of effect size statistics is that "authors must…

Provides tables of critical values for determining statistically significant discrepancies between Wechsler Verbal/Performance IQ and Wechsler Individual Achievement Test subtests and composite scores based on predicted-achievement method. Recommends that tables be used when statistically significant and diagnostically meaningful Verbal…

The purpose of the present study was to explore the effect of both short- and long term Child-Centered Play Therapy on teacher-student relationship stress. Teachers identified 58 students exhibiting emotional and behavioral difficulties who were randomly assigned to one of two treatment groups. Students in the short-term intensive play therapy…

Explains that an initial criterion to determine severe discrepancies and relative strengths and weaknesses is significant difference between regressed standard scores. Presents tables as convenient method to determine magnitude of discrepancy required for significance at common reliability and intercorrelation values. Shows prevalences of…

Reviews a recent paper by Levy (1982) which concluded that a new format of the Peabody Picture Vocabulary Test was valid for autistic children. Claims the analysis was inappropriate and presents a statistical test to compare differences between independent mean differences. Includes a reply by Stine Levy. (Author/JAC)

One hundred elementary- and middle-school students were administered the Universal Nonverbal Intelligence Test (UNIT; B.A. Bracken & R.S. McCallum, 1998) and the Leiter International Performance Scale-Revised (Leiter-R; G.H. Roid & L.J. Miller, 1997). Correlations between UNIT and Leiter-R scores were statistically significant ( p less…

Within the context of a counterbalanced design, 102 students from either a high school or a large Southeastern university were administered two versions of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A): a computer-administered version (CA) and a paper-and-pencil version (PAP). Time between testing sessions was approximately…

Contends that erroneous conclusions concerning intraindividual strengths may result when comparing scaled scores on subtests of The Test of Reading Comprehension. Examination of scaled scores may seem to indicate that a given student has performed better on one subtest than on another when the difference between the two scores is not statistically…
