This article responds to comments (EC 629 869-70) on a study on the reliability of the Modified Checklist for Autism in Toddlers (M-CHAT), a early detection screening test. It addresses concerns relating to clinic vs. population samples, data analysis, use of a parent questionnaire only to identify autism, and the age of screening. (Contains 6…

Two studies compared multidimensional self-concept measures in preadolescents. Findings indicated that the Self-Description Questionnaire and Self-Perception Profile for Children were highly correlated and comparable in reliability, stability, subscale interrelations, and associations with others' evaluations. Correspondence among various…

This paper describes the development of the Behaviour Function Inventory (BFI), an instrument designed to assess particular disorders of psychological development and functioning in children with developmental disorders including autism. A study of the reliability and validity of the scale indicated that the BFI provides precise information on the…

Conducted meta-analysis of preschool and early elementary school self-esteem instruments, using reliability as criterion variable and different aspects of methodology used in testing an instrument as predictor variables. Found that reliability could be predicted by study setting, number of items in the scale, age of children being studied, method…

This paper reports data on the psychometric relationship between personality traits (Big Five), and preference for particular assessment methods in an Australian sample of University students (N=125). Reliability analysis showed that participants tended to have consistent attitudes toward assessment methods, across disciplines (e.g., History,…

The use of anti-epileptic medications (AEDs) is much higher in individuals with intellectual disabilities than in the general population. As many of these individuals rely on such medications, clinicians should consider psychometrically sound instruments for assessing adverse side effects of these medications as one aspect of routine clinical…

Given that there is a continual need for school counselors to describe and account for what they do, it follows that an instrument that can be used to collect relevant process data is warranted. The importance of collecting process data describing school counselor practice is widely supported as a component of accountability. However, the lack of…

The results of a study examining the psychometric quality of a pictorial scale to measure perceived physical competence, perceived cognitive competence and perceived social acceptance by peers and caregivers in individuals with intellectual disabilities are reported. The scale was administered twice to 100 subjects. The stability of the scale…

This chapter highlights the need for incorporating institutional and societal context into institutional research in order to ensure accurate interpretation of data.

Test-retest reliability of the Test of Variables of Attention (T.O.V.A.) was investigated in two studies using two different time intervals: 90 min and 1 week (plus or minus 2 days). To investigate the 90-min reliability, 31 school-age children (M = 10 years, SD = 2.66) were administered the T.O.V.A. then read ministered the test 90 min afterward.…

Emerging data support the construct validity of component process variables of learning and memory within the Hopkins Verbal Learning Test-Revised (HVLT-R; Brandt & Benedict, 2001); however, the test-retest reliabilities of such measures are heretofore largely unknown. This study reveals generally modest-to-low 1-year test-retest stability for…

A total of 1,247 college students participated in this study on the effect of scale format on the reliability of Likert-type rating scales. The number of response categories ranged from 3 to 9. Anchor labels on the scales were provided for each response option or for the end points only. The results indicated that the scales with few response…

This paper discusses the sensitivity of instruments used to measure knowledge and attitudes toward older people. Existing standardized measurement instruments are reviewed, including a detailed examination of Palmore's Facts on Ageing Quiz (FAQ). A recent study conducted by the research team into the knowledge and attitudes of support workers (n =…

This article describes the initial development and psychometric evaluation of an ins trument for use with secondary students to measure various perceptions about class activities. The instrument--Student Perceptions of Classroom Quality (SPOCQ)--focuses on meaningfulness, challenge, choice, self-efficacy, and appeal, constructs central to learning…

This study examined the factor structure, internal consistency, concurrent validity, discriminant validity, and discriminative validity of the Posttraumatic Cognitions Inventory (PTCI; E. B. Foa, A. Ehlers, D. M. Clark, D. F. Tolin, & S. M. Orsillo, 1999) in a sample of 112 individuals who had experienced a serious motor vehicle accident. Results…
