Smoking onset in adolescence: a person-centered analysis with time-varying predictors.

Predictions from smoking-specific versus contextual models of smoking onset were tested with data from a 4-wave sample with 1,364 adolescents. Predictor variables were derived from stress-coping theory, social influence theory, and problem-behavior theory. In addition to groups of abstainers and experimenters, cluster analysis of smoking data indicated 3 groups who showed onset either in 7th grade (early onset), 9th grade (intermediate onset), or 10th grade (late onset). Almost all study variables discriminated the smoking groups from the abstainers. The onset groups were discriminated by Group X Time interactions showing differential changes in predictors (increases in risk factors and declines in protective factors), which occurred just prior to onset. The results generally support a contextual model of the onset process.     

Burnout and Depression Among Roman Catholic Secular,Religious, and Monastic Clergy

Burnout and depression among Roman Catholic secular, religious order, and monastic (Cistercian) priests was investigated using the Maslach Burnout Inventory (MBI) and the Center for Epidemiological Studies-Depression (CESD) scale. Additionally, a Self-Report-Inventory (SRI) was included requesting information on demographics as well as four categories of predictor variables (vocational satisfaction, social support, spiritual activities, and physical environment) associated with burnout and depression. All participants were randomly selected. The survey yielded a return rate of 90.67%. Secular clergy reported significantly greater emotional exhaustion than did monastic clergy. Secular priests also had significantly greater depression (72%), when compared to religious (40.8%) and monastic (39.5) clergy. Overall group comparisons revealed that secular clergy experienced the highest degree of burnout and depression, monastics the least, and religious priests falling in between. The lack of social support and sense of isolation, for secular clergy, were key elements associated with their experience of both burnout and depression.

Influence of win-loss ratio on performance,satisfaction and preference for opponents

Hypotheses about the preference for opponents in competitive situations, about performance under various win-loss ratios, and about task and opponent satisfaction under various win-loss ratios were tested. A 5 × 5 latin square with four replications and a repeated measure factor of trials was the design used with 20 female college students as subjects. The five different win percents were W₁₀, W₃₀, W₅₀, W₇₀, and W₉₀. A manipulative maze task was used with subjects receiving 20 trials against each of five confederate opponents. Results indicated that (a) when a person knows little or nothing about her ability level she initially prefers to compete with opponents of low ability but with each subsequent contest opponents of higher ability levels are preferred; (b) subjects performed better in the W₅₀ condition; (c) task satisfaction is higher when the percent of wins is equal to or greater than the percent of losses; and (d) opponent satisfaction is greater for opponents who perform equal to or better than the subject.     

Vocational Preference Inventory High Point Codes and Educational Preferences

This study reports normative data describing the combinations of various VPI high point codes associated with educational preferences classified into one of six of Holland's occupational environments and an undecided category. Eight hundred thirty-one male and 129 female college freshmen were queried regarding their educational preferences and were administered the VPI directly prior to college enrollment. The comparisons between preferences and VPI combinations revealed that Intellectual and Realistic, Social and Enterprising, Conventional and Enterprising, and Social and Artistic, seem to go together frequently for male students. The female sample revealed that Social and Artistic VPI codes were common.     

A comparison of the thurstone method of multiple factors with the hotelling method of principal components

The factors found by the Hotelling method of principal components present the same necessity for rotation as those found by the Thurstone method of multiple factors.The Thurstone method of multiple factors is here found superior to the Hotelling method of principal components, and is suggested as the method of choice for all problems requiring the determination of elemental components from a group of related variables, since it was found on every point of comparison that, when applied to a correlation matrix of unknown communalities, the Thurstone method was more accurate than the Hotelling method, and also required much less time.
