The reliability of Attention-Deficit/Hyperactivity Disorder (ADHD) rating scales in children with mental retardation was assessed. Parents, teachers, and teaching assistants completed ADHD rating scales on 48 children aged 5-12 diagnosed with mental retardation. Measures included the Child Behavior Checklist (CBCL), Conners Rating Scales, the…

Current accountability policy that bases assessment on validity and reliability criteria in the positivist research tradition is counterproductive to serving adult learners and their communities. In this article, we outline a framework for accountability that allows for the emergence and demonstration of the full range of program outcomes and…

First an overview is given about the actual national and international situation concerning standardized testing. Then two major reasons are presented why accountability systems based on standardized testing have become so widespread: (a) the missing validity and reliability of teachers' assessment of students' achievement, and (b) the important…

Analysis of continuous variables sometimes proceeds by selecting individuals on the basis of extreme scores of a sample distribution and submitting only those extreme scores to further analysis. This sampling method is known as the extreme groups approach (EGA). EGA is often used to achieve greater statistical power in subsequent hypothesis tests.…

Hierarchical agglomerative cluster analysis (HACA) may yield different solutions under permutations of the input order of the data. This instability is caused by ties, either in the initial proximity matrix or arising during agglomeration. The authors recommend to repeat the analysis on a large number of random permutations of the rows and columns…

The Mood and Feelings Questionnaire (MFQ) is examined for its utility in screening youth in juvenile justice settings for depression. In a cross-sectional study conducted at King County Juvenile Detention Center, a representative sample of 228 detained adolescents complete structured assessments, including the MFQ and the Massachusetts Youth…

This paper provides the results of two studies designed to evaluate a newly constructed self-report instrument, the Sexual Abuse Questionnaire (SAQ). The SAQ was designed as a brief screening device to aid in the identification of a childhood sexual abuse history. A "unique" feature of the SAQ is the inclusion of a number of non-face…

The Test for Creative Thinking-Drawing Production (TCT-DP), its design, concept and evaluation scheme as well as experiences and results of application are described. The test was designed to mirror a more holistic concept of creativity than the mere quantitatively oriented, traditional divergent thinking tests. The specific design using figural…

Grade point average (GPA) often correlates highly with variables of interest to educational researchers and thus offers the potential to greatly increase the statistical power of their research studies. Yet this variable is often underused in marketing education research studies. The reliability and validity of the GPA are closely examined here in…

This article provides a typology of reasons for conducting mixed-methods research in special education. The mixed-methods research process is described along with the role of the rationale and purpose of study. The reasons given in the literature for utilizing mixed-methods research are explicated, and the limitations of these reason frameworks…

Many colleges and universities receive thousands of applications for freshman admission every year. To facilitate the process of evaluating each and every applicant in a relatively short amount of time, schools often devise quantitative ratings scales to summarize student characteristics. The ratings give readers a shorthand way to communicate the…

This study develops a quality of life instrument for older Japanese people experiencing dementia (QLDJ). Quality of life (QL) for these older adults is defined as a three dimensional construct including 1) interacting with surroundings, 2) expressing self, and 3) experiencing minimum negative behaviors. From 53 items in the initial item pool, 24…

The HEXACO Personality Inventory (HEXACO-PI) operationalizes the six factors obtained from lexical studies of personality structure in several languages. In this study, psychometric properties of the HEXACO-PI were assessed using a community adult sample and also using observer reports, thereby extending the previous investigation relying only on…

Psychometric properties of the Parent-Child Relationship Inventory (PCRI) were examined using data collected from adolescents and their parents in the Fullerton Longitudinal Study. Results revealed acceptable internal consistency for most scales and moderate to high 1-year stability for all scales. Both parents' PCRI scores correlated with their…

Traditional standardized, norm-referenced assessments are used most often to determine children's eligibility for specialized services. These traditional tests have at least two drawbacks: (a) test items and activities often do not reflect children's functional repertoires; and (b) outcomes are difficult to link directly to goal development,…
