Romantic relationships and the physical and mental health of college students

This study tested the hypothesis that, analogous to married individuals, college students in committed romantic relationships experience greater well-being than single college students. In a sample of 1,621 college students, individuals in committed relationships experienced fewer mental health problems and were less likely to be overweight/obese. There were no significant differences between groups in frequency of physical health problems. Examination of 2 models suggested that being in a committed romantic relationship decreases problematic outcomes largely through a reduction in sexual partners, which in turn decreases both risky behaviors and problematic outcomes. These results are discussed in the context of how premarital dating relationships may contribute to understanding of the observed association between marriage and well-being.     

INCREASING THE ACCURACY OF CORRECTIONS FOR RANGE RESTRICTION: IMPLICATIONS FOR SELECTION PROCEDURE VALIDITIES AND OTHER RESEARCH RESULTS

The common practice in meta-analyses and in individual studies of correcting for direct range restriction even though range restriction is actually indirect has long been known to lead to undercorrection, but this error has been assumed to be small. Using validity generalization data sets for 4 jobs, this study calibrated this error by comparing meta-analysis results based on corrections for direct range restriction with the more accurate results from a recently developed method of correcting for indirect range restriction. It was found that, on average, correction for direct range restriction resulted in substantial underestimation of operational validities for both job performance measures (21%) and training performance measures (28%). In addition, 90% credibility values were on average underestimated by 38%–40%. In addition to the implications for personnel selection, these findings suggest that similar underestimation of important relationships has occurred in other areas of research, with potential implications for theory development.     

The Dynamics of Creative Teaching

The following is a qualitative portrait of a creative teacher and her teaching process. Over a period of six months, five interviews were conducted with the teacher before, during, and following a university course in teacher education on instructing diverse learners. Additional interviews were conducted with six students at the beginning and end of the course and with the teacher's husband following the course. Additional data sets include classroom observations revealed in field notes, personal memos, and course materials. The overarching themes represented constructs involving intense and thorough course preparation, teacher‐student connections, and reflective teaching. Sub‐themes guiding the process of creative teaching emerged including constraints placed on preparation and reflective teaching, an awareness of self and students within the process of preparation and connection, feedback from colleagues and students guiding the connection and reflective teaching, and the values and goals formed from personal history and philosophy of life shaping all three major themes. This case study of creative teaching possesses characteristics resembling creative acts in other domains (e.g., art, literature, physics, economics) and presents a model for the education of future teachers.     

Career lndecision and Family Enmeshment

In this study the relationship between career indecision and family-of-origin enmeshment is examined. Six hundred and four undergraduate and graduate students (classes randomly selected) were administered the Career Decision Scale and two scales (Intergenerational Individuation and Triangulation) from the Personal Authority in the Family System Questionnaire. A simultaneous multiple regression analysis on the indecision scale, using four predictor variables, yielded three significant variables (age, graduate/undergraduate status, and individuation) that accounted for 11% of the variance. Graduate students were more decided than undergraduate students and those who were more decisive tended to be older and more individuated.     

INTERPRETING THE RESULTS OF META-ANALYTIC RESEARCH: A COMMENT ON SCHMITT, GOODING, NOE, AND KIRSCH (1984)

This comment shows that the conclusion of Schmitt, Gooding, Noe, and Kirsch (1984) that their meta-analytic findings are inconsistent with earlier validity generalization work is in error. The findings in their study that less variance than previously reported was due to sampling error are a result of their larger average sample sizes. Their claim that, after sampling error variance was accounted for, much unexplained variance remained, is incorrect. This error is demonstrated to be a result of their exclusive concentration on percentages and consequent failure to examine amount of observed and residual variance.     

ESTIMATION OF EMPLOYMENT VALIDITIES BY LESS EXPERIENCED JUDGES

In a previous study, Schmidt, Hunter, Croll and McKenzie (1983) demonstrated that estimates of the validity of cognitive tests made by highly trained and experienced judges are more accurate than empirical estimates obtained from small-sample validity studies. The present study examined whether less experienced judges could also produce accurate estimates. Twenty-eight recent Ph.D.'s in I/O Psychology estimated observed validities for the same 54 job-test combinations used by Schmidt et al. (1983). The estimates of these judges contained about twice as much random error as the experts' estimates. Systematic error of the less experienced judges was also greater than that of the experts (.0732 vs .019). The systematic errors of the two sets of judges were in opposite directions: less experienced judges overestimated validities, on average, while experts underestimated them. The results show that the estimates of less experienced judges contain less information than those of experts, but also that averages of estimates of several less experienced judges are as accurate as those obtained from small-sample empirical studies.
