Relationship of drug use to involvement in school, home, and community activities: results of a large survey of adolescents.

All 7th, 9th, and 11th grade students in 129 school districts responded to a 466-variable survey that primarily assessed drug use but also contained questions about involvement in various activities. Meaningful relationships were obtained between students' involvement in school, family, and church activities and reported use of tobacco, alcohol, and marijuana. Factors reflecting the extent of parental supervision were also related to the reported use of those substances.

Reaction time of the fingers with responses measured on a typewriter keyboard.

Reaction times on each of the eight fingers were obtained for 24 skilled typists using an electric typewriter and a mechanical timer. Repeated-measures analysis of variance indicated significant differences among the mean reaction times of the eight fingers. Scheffé's multiple-comparison procedure indicated that the mean reaction time of each finger differed from that of every other finger and that the mean reaction time of the finers on the left hand was significantly slower than the mean reaction time of fingers on the right hand. The average inter-class correlation coefficient among the fingers was .92 which indicated rank-order of reaction times to be similar across fingers.

Language impairment evaluation in aphasic patients: developing more efficient measures.

Two short forms of the Porch Index of Communicative Ability (PICA) were derived using data from 50 adult aphasic patients. Subtest, modality and overall intercorrelations, internal consistency reliability estimates, means and standard deviations were computed for both forms and full-length test. Results indicate that the short forms are equivalent. Further, they seem to be measuring the same traits as the long form, have only slightly lower reliability, and have practically identical means and standard deviations across all subtest, modality and overall scores.
