A 21-item scale combining and modifying an environmental paradigm and a social paradigm was used in 2 surveys. This paper compares attitudinal dimensions resulting from factor analysis. Similarities in terms of relationships between scores on the scale and preferences for energy-related options were also assessed. (Author/CW)

Structured interviews with a random sample of adult basic education students in Iowa (N=323) and an academic ability test administered to a 50 percent subsample identified reasons for participation. Factor analysis revealed 10 motivational dimensions, and cluster analysis categorized 6 subgroups: mainstream women, the urged, young adults, the…

A nationwide study examined relationships between 201 prelingually deaf adolescents' reading comprehension scores and their hearing mothers' communication strategies and skills.

Reports on an experiment undertaken to explore further whether language proficiency is divisible or unitary, using the principal factor analysis, and to identify the factors involved with the scores of 58 subjects of similar language and cultural backgrounds. (Author/CB)

Examines reliability and validity of two versions of Hispanic Stress Inventory (HSI), a new instrument to assess psychosocial stress among Hispanic adults. Subscale scores found to correlate highly with criterion measures of distress. Tests showed internal consistency and supported HSI reliability. Need for further evaluation discussed. (TES)

To examine the outcomes from traditional undergraduate degree programs, 7,577 recent college graduates over 30 were surveyed. Factor analysis structured 24 outcome variables into 5 categories in which adults felt their education had a major impact: self-directed learning, human/artistic development, communication skills, logic/problem solving, and…

Examined attitudes of ambivalence and hostility toward children by drawing on a random sample of 600 couples in the early years of marriage.

Four dimensions of marital well-being--happiness, equity, competence, and control--emerged in a factor analysis of 12 items asking 199 Black and 174 White newlywed couples to evaluate their overall marital quality. Dimensions were related to respondents' gender, cohabitation history, education, and income, differentially for Blacks and Whites. (TE)

The relationships between speech parameters and speech intelligibility of 40 severely to profoundly hearing-impaired adults were studied. Regression analysis revealed that speech intelligibility was predicted by a cognate-pair voice-onset-time difference measure and a measure of the stability of the volume-velocity rise time. (Author/JDD)

Uses data from 991 Mexican-Americans in six states to develop a nine-item acculturation measure based on respondent's language and self-definition as insider or outsider. Describes factor structure and construct validity. Contains 28 references. (SV)

Three papers--comments, a reply to comments, and a rejoinder--discussing a conclusion about the nature of general intelligence based on the size loadings of a psychomotor test of discrimination reaction time are presented. The use of Spearman's "g" is the center of the controversy. (TJH)

A career ladder affecting the work structure and career opportunities of teachers was studied to determine effects on teacher attitudes. Responses of 389 elementary through high school teachers to career ladder work efforts, work of schools, peer supervision, and career growth opportunities and stability were affected by the design.
