ADAPTABILITY TO CHANGING TASK CONTEXTS: EFFECTS OF GENERAL COGNITIVE ABILITY, CONSCIENTIOUSNESS, AND OPENNESS TO EXPERIENCE

We examined the extent to which cognitive ability, Conscientiousness, and Openness to Experience predict decision-making performance prior to and after unforeseen changes in the task context. Seventy-three undergraduates made decisions on a series of 75 problems during a 3-hour computerized simulation. Unbeknownst to participants, the rules used in determining correct decisions changed after problems 25 and 50. Effects of the individual differences on decision-making performance became significantly stronger after the changes. Only cognitive ability explained variance in prechange performance. Individuals with higher cognitive ability made better decisions. After the change, the cognitive ability effect increased and the effects of Conscientiousness and Openness became statistically significant. As expected, those with high Openness made better decisions. Unexpectedly, those with low Conscientiousness made better decisions. Subsequent analyses revealed that this surprising effect for Conscientiousness was due to the traits reflecting dependability (i.e., order, dutiful-ness, deliberation) rather than volition (i.e., competence, achievement striving, self-discipline).     

INVESTMENT IN WORK AND FAMILY ROLES: A TEST OF IDENTITY AND UTILITARIAN MOTIVES

This study compared identity and utilitarian motives as predictors of time investment in work and family roles, using structural equation modeling with a sample of 623 working men and women. We tested within-role and cross-role relationships as well as the reciprocal effects of time invested in one role on time invested in the other role. As predicted, identification with a role was positively related to time invested in that role. However, findings for role utility were more complex. Time investment was positively related to both the pleasure and displeasure associated with a role. These findings suggest that people not only seek pleasure from roles but also invest time coping with role displeasure. The cross-role findings supported resource drain and accommodation but not compensation as explanations of work-family linking mechanisms. Gender analyses suggested that, for men, increased work time investment reduced time devoted to family, but increased family time investment did not affect time devoted to work. However, for women, increased time investment in either work or family reduced time devoted to the other role. These findings suggest that men may have greater reserves of time from roles other than work and family that make it unnecessary for them to draw from work time to meet increased family demands.     

THE MEASUREMENT OF WORK: HIERACHICAL REPRESENTATION OF THE MULTIMETHOD JOB DESIGN QUESTIONNAIRE

To study the changing nature of work, researchers need measures of work that are valid and comprehensive. One potentially useful measure of work is the Multimethod Job Design Questionnaire (MJDQ; Campion, 1988), which was developed to assess 4 general approaches to work design (i.e., motivational, mechanistic, biological, perceptual-motor). Although the MJDQ holds promise as a general measure of work, little information is available regarding its psychometric properties. This study examines the MJDQ, using alternative hierarchical factor structures to represent work at varying levels of abstraction. Little support was found for the 4-factor structure corresponding to the work design approaches underling the MJDQ or for various hierarchical factor structures that simultaneously depicted general and specific aspects of work. However, a 10-factor first-order model received good support and may provide a useful basis for scoring and interpreting the MJDQ in future research.     

AN EXPLORATORY INVESTIGATION INTO THEORETICAL MECHANISMS UNDERLYING REALISTIC JOB PREVIEWS

This research explored complex theories about why realistic job previews (RJPs) deter turnover. After designing an RJP booklet about nursing work, we delivered this RJP to 82 newly hired nurses during orientation, while presenting a traditional recruitment brochure to 76 other nurses. Nurses also completed surveys on two occasions, assessing processes commonly thought to translate RJP influence: met expectations; commitment; perceived employer caring; coping efficacy; and value orientation. The RJP lowered voluntary quits: 8.5% of nurses given previews quit versus 17.8% of control nurses (p ≤ .10). Using structural equation methodology (SEM), we compared two integrative formulations portraying different structural networks among mechanisms behind RJP influence. Observed data appeared more consistent with an interdependent than independent mediating process model. In particular, these data suggest that met expectations have direct and indirect effects through other mediators (e.g., organizational concern and coping) on turnover precursors–namely, job satisfaction and organizational commitment.     

IDENTIFYING OPTIMAL PREDICTOR COMPOSITES AND TESTING FOR GENERALIZABILITY ACROSS JOBS AND PERFORMANCE FACTORS

The initial examination of validity generalization in the Army Selection and Classification Project used data from a concurrent validation sample of 4,039 job incumbents drawn from a representative sample of nine jobs. The available data consisted of 24 predictor scores and five job performance factor scores on each individual. The major objectives were to determine (a) the degree of validity generalization across the major components of performance, with the job held constant, and (b) the degree of validity generalization across jobs within each major performance factor. After reducing the predictor set by eliminating variables that added no information, a modified confirmatory analysis was used to test the hypotheses that one equation would fit the data from all performance components and that one equation would fit the data from all jobs, given a particular performance component. The major findings were that different predictor equations were needed for each of the five criterion factors. For generalization across jobs, within each criterion factor, one equation fit the data for four of the five performance components. Different prediction equations were required for the component that reflects proficiency on the technical tasks specific to each job.     

PROJECT A VALIDITY RESULTS: THE RELATIONSHIP BETWEEN PREDICTOR AND CRITERION DOMAINS

A predictor battery of cognitive ability, perceptual-psychomotor ability, temperament/personality, interest, and job outcome preference measures was administered to enlisted soldiers in nine Army jobs. These measures were summarized in terms of 24 composite scores. The relationships between the predictor composite scores and five components of job performance were analyzed. Scores from the cognitive and perceptual-psychomotor ability tests provided the best prediction of job-specific and general task proficiency, while the temperament/personality composites were the best predictors of giving extra effort, supporting peers, and exhibiting personal discipline. Composite scores derived from the interest inventory were correlated more highly with task proficiency than with demonstrating effort and peer support. In particular, vocational interests were among the best predictors of task proficiency in combat jobs. The results suggest that the Army can improve the prediction of job performance by adding non-cognitive predictors to its present battery of predictor tests.     

Eating Disorders on Campus: A Procedure for Community Intervention

Concern for students with eating disorders and concern for the environment served as the catalyst for the development of a procedure for responding to eating disorders. The procedure, which relies heavily on residence hall staff, is presented here, with emphasis on training, prevention, and issues in implementation.     

Online dating system design and relational decision making: Choice,algorithms, and control

One of the most popular ways to initiate romantic relationships today is through online dating. Typical dating systems follow one of three formats, see‐and‐screen (e.g., Match.com ), algorithm (e.g., eHarmony.com ), and blended (e.g., OkCupid.com ), which differ in the amount of individual control and algorithmic involvement they offer users. Do different features affect daters' decisions and expectations regarding relational development with selected partners? Study 1 indicated that although daters appreciated the personal control over mate selection afforded by see‐and‐screen systems, they also enjoyed using algorithmic systems. Study 2 found that blended systems provided “the best of both worlds” by offering dual benefits of control and algorithmic validation during mate selection. Findings shed light on self‐determination theory, decision making, and relationship formation more broadly.
