STATISTICAL POWER AND COST IN TRAINING EVALUATION: SOME NEW CONSIDERATIONS

Two ways to reduce the costs of training evaluation are examined. First, we examine the potential for reducing the costs of training evaluation by assigning different numbers of subjects into training and control groups. Given a total N of subjects, statistical power to detect the effectiveness of a training program can be maximized by assigning the subjects equally to training and control groups. If we take into account the costs of training evaluation, however, an unequal-group-size design with a larger total N may achieve the same level of statistical power at lower cost. We derive formulas for the optimal ratios of the control group size to the training group size for both ANOVA and ANCOVA designs, incorporating the differential costs of training and control group participation. Second, we examine the possibility that using a less expensive proxy criterion measure in place of the target criterion measure of interest when evaluating the training effectiveness can pay off. We show that using a proxy criterion increases the sample size needed to achieve a given level of statistical power, and then we describe procedures for examining the tradeoff between the costs saved by using the less expensive proxy criterion and the costs incurred by the larger sample size.     

NEW DEVELOPMENTS IN THE USE OF MEASURES OF HONESTY INTEGRITY, CONSCIENTIOUSNESS, DEPENDABILITY TRUSTWORTHINESS, AND RELIABILITY FOR PERSONNEL SELECTION

This paper is the fourth in a series of reviews of the use of measures of honesty, integrity, conscientiousness, dependability, trustworthiness, and reliability for personnel selection (see Sackett & Decker, 1979; Sackett & Harris, 1984; Sackett, Burris, & Callahan, 1989). New developments reviewed include an examination of professional and congressional inquiry into this area of testing, rapid growth of the validity data base, new insight into similarities and differences between different tests, and links to the Big Five personality dimensions. Inquiries into relationships with other constructs, including cognitive ability, moral reasoning, and social desirability are reviewed, as are applicant reactions to these tests. The effects of the Civil Rights Act of 1991 and the Americans with Disabilities Act are considered.     

The Politics of Counseling: Looking Back and Forward

This article examines reasons for the counseling profession's movement away from its activist roots toward policies and agendas that are less socially engaged. Concern with individualism, struggle for public acceptance, continued reliance on narrow research interests, and increased emphasis on accreditation and credentialing are all discussed as factors contributing to the counseling profession's inability to advocate for effective social change.     

Interpersonal attraction as a function of extreme gender role adherence

Although gender-specific constructs of hypertraditionality qualitatively differ (e.g., hyperfemininity and hypermasculinity), we view them as analogous constructs that can predict similarity/attraction effects. The similaritylattraction paradigm showed that individuals find attractive the traits in others that are similar to their own traits. We suggest that this effect applies to levels of hypertraditionality, as measured by the hyperfemininity and hypermasculinity personality scales. The studies were conducted to test this hypothesis. We began by manipulating stranger similarity in an attraction experiment. Results showed that similarity of hypertraditionality led to attraction. Women preferred target persons similar to themselves in hypertraditionality. Data from men revealed an unexpected interaction. Low hypermasculine men preferred women similar to themselves in hypertraditionality, yet high hypermasculine men did not distinguish between female strangers based on the stranger's level of hypertraditionality. We then studied dating couples. These couples provided real-world data that supported and expanded the laboratory observations. We found a significant positive correlation between the partners' levels of hypertraditionality. The implications of attraction based on hypertraditionality may provide insights for future studies of relationship formation and maintenance.     

Men without jobs: Some correlates of age and length of unemployment

Measures of reported health change, financial stress, financial strain, and commitment to the labour market were used with a sample of 954 unemployed working-class men, selected to cover equally all levels of age and several levels of length of unemployment. It was found that psychological deterioration, financial stress and strain, and labour market commitment were greatest among middle-aged unemployed men. Deterioration in health and degree of financial strain were found to be greater among men unemployed for longer periods in contrast with those who had more recently become unemployed, but no association was observed between length of unemployment and the measures of financial stress and commitment to the labour market. The probability of having an employed wife was found to be negatively associated with length of unemployment, consistent with the operation of a household strategy for income maintenance.     

Predicting Success in Vocational Training By Using the GATB

This study examined the relationship between the General Aptitude Test Battery (GATB)and class performance of eleventh- and twelfth-grade high school students enrolled in the Current River Area Vocational School, Doniphan, Missouri. Teachers' grades were used as the dependent variable, and the nine independent variables were scores taken from the aptitude factors of the GATB. The stepwise multiple regression technique was used to determine the optimal set of predictors to be used in establishing a regression equation. The results of the project should help in counseling prospective trainees toward trade or shop areas and tentative vocational planning. If not used out of perspective, the G variable in the GATB was the best single predictor of success; the best combination of variables was the G, N, P, F, and M aptitude factors.
