Relative adiposity (%Fat) was measured using a smartphone-based application in a convenience sample of adults aged 20-52 years (n = 32, 68.7% female, 84.3% White/Caucasian, 26.7 ± 3.5 kg/m2) across different body positions (Anterior versus Posterior) on consecutive days (Day 1 versus Day 2). A reference photo was obtained from the posterior view…

Reliability and validity of self-reported behavior within a deviant population are examined using data from 2 interviews with 323 narcotics addicts conducted 10 years apart (1974-75 and 1985-86). Results complement existing reliability and validity studies of alcohol use, and suggest that quality information can be obtained from heroin users. (SLD)

This investigation examined the three-year stability of WISC-R IQs for a balanced sample of Anglo, Black, and Mexican-American handicapped children. No significant differences in mean IQs were found across the three ethnic groups, although WISC-R Verbal and Performance IQs varied significantly over the test-retest period. (Author/BS)

Five studies involving medical students over a four-year period were conducted to examine the reliability and validity of the Medical Helping Relationship Inventory (MHRI)--an instrument for evaluating medical communication skills. Evidence of the MHRI's construct validity, convergent validity, and discriminant validity is discussed. (SLD)

Scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal, Performance, and Full Scales were compared for 26 adolescents with educable mental handicaps. The WAIS-R, while strongly correlated with the WISC-R, provided higher scores on all three scales. Several WISC-R…

The stability of the Kaufman Assessment Battery for Children (K-ABC) was studied by examining its performance over a 5-year interval with 16 non-handicapped children aged 45 to 61 months at the beginning of the study. Global scale stability coefficients (corrected for restriction in range) for Time 1 testing (age 4 years) and Time 4 testing (age 9…

This report is the Proceedings of the third conference of its type. Included are 23 of the 25 papers presented at the conference, discussion of these papers by invited discussants, and symposium papers by a group of leaders in adaptive testing and latent trait test theory research and applications. The papers are organized into the following…

The Stability of Self Scale has been used to infer the stability of self-concept from responses collected on a single occasion. Using the large, nationally representative Youth in Transition data for 10th grade boys in public high schools in 1966, Stability of Self responses were related to the variability in self-esteem responses collected in 4…
