Studies test validity of the instruments used to measure intrinsic motivation. Compares behavioral and self-report measures among undergraduates of intrinsic task interest to momentary mood, long-term motivational orientation, and interest in competing activities. Finds the behavioral measure depends on how treatments affect interest in…

Evaluation of the home environments of 64 families of children with severe disabilities 7 and 9 years after the initial assessment found a high degree of stability, especially on the Family Environment Scale (FES). However, internal consistency reliability of the FES was lower for these families than in the standardization samples. (Contains…

This article is the third contribution to a research methods series dedicated to getting good results from survey research. In this series, "good results" is a stenographic term used to define surveys that yield accurate and meaningful information that decision makers can use with confidence when conducting program evaluation and policy assessment…

In fall 1978, a study was conducted at Eastfield College to determine the desirability of using a writing sample as part of the student assessment and advisement process. At an orientation session attended by 1,643 entering students, an entry-level assessment was conducted, consisting of a writing sample; an objective English composition test; the…

Group process and rating techniques were used to create a scale for measuring severity and frequency of 24 problem behaviors in institutionalized mentally retarded persons. A substantial correlation was found between scores and staff-time allocations, indicating usefulness of the scale as a predictor of staffing requirements for behavior…

Locally developed occupational tests were administered to 16- and 17-year-olds in a government-sponsored vocational education program in the United Kingdom over a six-month period in 1984. Job skills were tested in two occupational areas: use of a micrometer and invoice completion. Some performance tests were designed by researchers and some by…

The influence of day-to-day variation in teacher performance on the reliability and validity of teacher assessment was examined. An attempt was made to identify and quantify sources of score variation attributable to differences in teacher performance, day of observation, observers, and test subscales; and to determine their effects on reliability…

Using data collected through telephone interviews with a national sample of adults, this study searched for evidence as to whether interviewers have stronger effects on the responses given to a wide range of questions by older people than on the responses of younger people. Responses to 30 items for which significant interviewer effects had…

To explore the appropriateness of the Rasch model for the vertical equating of a multi-level, multi-form achievement test series, both the Rasch model and the traditional Thurstone procedures were applied to the Listening Comprehension subtest scores of the Stanford Achievement Test. Two adjacent levels of these tests were administered in 1981 to…

Narrative data yield rich detail, insight, and information, but the personal and situational characteristics of coders (called value inertia and cognitive limitation biases) can affect data reduction. The effects of coder exposure to expected project outcomes and the level of coder research methodology sophistication were investigated. Coders,…

Current methods of obtaining reliability coefficients for mastery tests are laborious from a practitioner's perspective. Some methods require two test administrations; while others require access to computer facilities and/or advanced measurement and statistical procedures. This report provides tables from which practitioners can read such…

Discusses the conditions for validating customary phylogenetic procedures. Concludes that the requisites of homogeneity and completeness for proved short lineages seem satisfied by the Hennigian but not the Haeckelian procedure. The epistemological antinomy of the two procedures is emphasized for the first time. (Author/RH)

Participants (N=12) met individually with a counselor for 20 minutes each. The interviews were videotaped. Participants rated two types of recalled affect at the times of occurrence of each of six counselor nonverbal gestures. Results support moderate reliability for videotape-assisted recall ratings of recalled affect. (BH)

Assessed Wechsler Adult Intelligence Scale-Revised test-retest stability for 21 psychiatric and neurological patients. Test-retest interval ranged from 2-144 weeks (x=38 weeks). Subtest stability coefficients were highly significant, yet range of gain or loss for any single individual was comparatively large. Gain or loss was associated strongly…

Listeners compared 10 individuals' suitability of speech at three stages of treatment for stuttering (before, immediately after, and six months after) with 10 non-stutterers. Ten speaking situations with different demands were rated using a newly developed instrument. Results indicated the instrument can be scored reliably and the factor…
