research techniques for counselors: the multiple baseline

Practitioners in counseling must also be applied researchers. Counselors can no longer rely on intuition, personal opinion, or statistical studies to determine their effectiveness. In this article multiple baseline techniques are offered as applied research strategies for counselors who wish to evaluate the effects of the techniques they are using.     

THE ECONOMIC IMPACT OF JOB SELECTION METHODS ON SIZE, PRODUCTIVITY, AND PAYROLL COSTS OF THE FEDERAL WORK FORCE: AN EMPIRICALLY BASED DEMONSTRATION

In this study, job performance increases resulting from improved selection validity were measured empirically rather than estimated from the standard linear regression utility equations. Selection utility analyses based on these empirical measurements were carried out for most white-collar jobs in the federal government. Results indicate that selection of a one-year cohort based on valid measures of cognitive ability, rather than on non-test procedures (mostly evaluations of education and experience), produces increases in output worth up to $600 million for each year that the new employees remain employed by the government. Newly hired federal employees remain with the government an average of approximately 13 years, resulting in a total gain in output of almost $8 billion over this period. This gain represents a 9.7% increase in output among new hires. If total output is held constant rather than increased, new hiring can be reduced by up to 20,044 per year (a 9% decrease), resulting in payroll savings of $272 million for every year the new cohort of employees remains on the job. The percentage of new hires in the bottom decile of the non-test-selected job performance distribution     

Features of Families with Major Affective Disorders

This article reports the authors' observations on 22 families in which a young adult member has been diagnosed as manic-depressive, and on 11 families in which a member has been diagnosed as suffering from major schizoaffective disorder. All families could be described as extremely rigid and bound-up systems. Many of them were characterized by a "restrictive parental complementarity" and reciprocal delegation, and they shared certain cognitive features and assumptions. "Manic-depressive" families showed similarities as well as differences when compared with families in which there were schizophrenic and serious psychosomatic disorders.     

ASSESSING THE ECONOMIC IMPACT OF PERSONNEL PROGRAMS ON WORKFORCE PRODUCTIVITY

This article describes and illustrates the adaptation of the linear-regression-based decision-theoretic equations used to estimate the dollar impact of valid selection procedures on workforce productivity to the evaluation of intervention programs designed to improve job performance. The appropriate equations are derived and explained, methods for estimating equation parameters are discussed, and the use of these equations is illustrated by means of a hypothetical example. It is concluded that in the future these methods and equations will allow psychologists to make more accurate assessments of the impact of intervention programs on workforce productivity than has heretofore been the case.     

FURTHER WITHIN-SETTING EMPIRICAL TESTS OF THE SITUATIONAL SPECIFICITY HYPOTHESIS IN PERSONNEL SELECTION

The situational specificity hypothesis in personnel selection holds that variation in observed validity coefficients across studies for the same test and job is due to subtle variations from setting to setting in what constitutes job performance. This hypothesis therefore predicts that, if the setting does not vary, validity will not vary. Using data from a single large-sample validity study ( N = 1,455), this research generated numerous small-sample studies for which the setting (organization, job, test, criterion measure, applicant pool, time period, and sample size) was held constant. It was found that even under these circumstances there was substantial variability across studies in (a) observed validity coefficients, (b) significance levels, and (c) (using traditional data analytic methods) conclusions about the presence or absence of validity. These findings disconfirm the situational specificity hypothesis and argue strongly against traditional data-analytic procedures and the practice of reliance on single small-sample studies. In contrast to the erroneous conclusions produced by traditional data-analytic procedures, meta-analytic methods correctly estimated the population observed validity at .22 and correctly indicated that all between-study variance in observed validities was due to sampling error alone.
