RETEST EFFECTS ON IDENTICAL AND PARALLEL FORMS IN CERTIFICATION AND LICENSURE TESTING

Examinees who take credentialing tests and other types of high-stakes assessments are usually provided an opportunity to repeat the test if they are unsuccessful on initial attempts. To prevent examinees from obtaining unfair score increases by memorizing the content of specific test items, testing agencies usually assign an alternate form to repeat examinees. Given that the use of multiple forms presents both practical and psychometric challenges, it is important to determine if unwarranted score gains occur. Most research indicates that repeat examinees realize score gains when taking the same form twice; however, the research is far from conclusive, particularly within the context of credentialing. For the present investigations, two samples of repeat examinees were randomly assigned to receive either the same test form or a different, but parallel, form on the second occasion. Study 1 found score gains of about 0.79 SD units for 71 examinees who repeated a certification examination in computed tomography. Study 2 found gains of 0.48 SD units for 765 examinees who repeated a radiography certification examination. In both studies score gains for examinees receiving the parallel test were nearly indistinguishable from score gains for those who received the same test. Factors are identified that may influence the generalizability of these findings to other assessment contexts.     

Comprehensive School Counseling Programs: A Review for Policymakers and Practitioners

This article describes components of effective school counseling programs that have emerged from 30 years of empirical research and professional standards. Results are summarized in seven sections: core principles of school counseling programs, program resources, program interventions, program evaluation, program renewal, written policies, and program climate.     

Information Attributes as Related to Psychological Symptoms and Perceived Control Among Information Seekers in the Aftermath of Technological Disaster

The relationship among information attributes, psychological symptoms, and perceived control was examined among residents in the vicinity of Three Mile island who attended the Three Mile Island Health and Environmental Information Series on cancer, radiation, and epidemiology of cancer 6 years after the nuclear accident that had occurred and shortly before restart of the plant. Among course participants, greater understanding of information was associated with slightly fewer psychological symptoms. Higher rated reliability of information was associated with less perceived control. Findings are discussed with reference to information delivery under conditions of uncertainty.     

Psychological science in the public arena: Three cases of dubious influence

Psychological science has a great deal to contribute to social welfare in all societies, because the world's most pressing social problems are behavioral in nature—violence, hunger, drug abuse, environmental pollution, low worker productivity, poor educational outcomes, and so forth. Thus, psychological research can inform public policies to improve approaches to these important social problems. The relationship of psychological science to public policy is often troubled, however, by misunderstandings about the role of science in the policy making process. Many scientists fear that their research results will be "misused" by others whose values differ from those of scientists. Thus, psychologists are reluctant to publish research results that can be used to support policies contrary to their own values and hesitate to ask research questions that can generate politically incorrect results. In this article, I argue that psychological science has a primary responsibility to ask dangerous questions and to report results honestly, without fear of their use; that research is not translated directly into public policies; and that psychological science should not be perverted either by fear of political consequences or by compromising truth in a quest for power. Three research examples are given to illustrate the different faces of temptation to pervert psychological science in a misguided hope that scientists' own values will be reflected in public policies.     

Sexual satisfaction in long-term heterosexual relationships: The interpersonal exchange model of sexual satisfaction

This study examined the validity of the Interpersonal Exchange Model of Sexual Satisfaction (IEMSS) in long-term, heterosexual sexual relationships. The IEMSS proposes that sexual satisfaction depends on one's levels of rewards and costs in the sexual relationship, one's comparison levels (CL) for rewards/costs, and one's perceptions of the dyadic equality (EQ) of these rewards/costs. Sexual satisfaction is expected to be greater to the extent that, over time, levels of rewards (REW) exceed levels of costs (CST), relative reward levels (CLREW) exceed relative cost levels (CLcst ), and interpersonal equality of rewards (EQrew ) and of costs (EQCST) is perceived to exist. Married/cohabiting community volunteers and university alumni/staff completed two questionnaires, 3 months apart. The results obtained from this well-educated, relationally satisfied sample (N= 143) provided excellent support for the IEMSS. Hierarchical regression analysis revealed that each component of the model (REW - CST, CLrew - CLcst , and EQrew , EQcst ) added to the prediction of sexual satisfaction as expected, accounting for 75% of the variance. Repeated measurement of the IEMSS components offered a better prediction of sexual satisfaction than a one-time measure alone. Neither gender nor relationship satisfaction interacted with the IEMSS components. However, including relationship satisfaction (but not gender) in the model significantly improved the prediction of sexual satisfaction. It was concluded that the model should be revised to include relationship satisfaction. Both the exchange components of the IEMSS and sexual satisfaction uniquely predicted relationship satisfaction. The IEMSS offers a promising approach for understanding sexual satisfaction and its relationship to relationship satisfaction, as well as for reconciling inconsistent findings in the literature.
