Multidimensional Scaling in Counseling Research and Practice

The authors briefly describe the use of multidimensional scaling (MDS) in counseling. They discuss types of data that have been analyzed using MDS, kinds of MDS analyses, and the interpretation of MDS results and review MDS research relevant to vocational, family, group, and individual counseling. They also briefly discuss potential applications in counseling practice.     

Clamped Corticosterone (B) Reveals the Effect of Endogenous B on Both Facilitated Responsivity to Acute Restraint and Metabolic Responses to Chronic Stress

To determine the effects of both corticosterone (B) and chronic stressors on acute ACTH responses to restraint, young male rats were exposed to streptozotocin-induced diabetes, cold (5-7 degreesC) or intracerebroventricular (icv) neuropeptide Y (NPY) for 5 d and then exposed to restraint within 2 h after lights on. Two groups of rats were studied: intact and adrenalectomized replaced with B pellets that maintained plasma B in the normal mean 24-h range of intact rats. In addition to ACTH and B responses to restraint on d 5, body weight, food intake, fat depots, glucose and other hormones were measured to determine the role of stress-induced elevations in B on energy balance. ACTH responses to restraint were normal in intact rats subjected to diabetes or cold. By contrast, there was no ACTH or B response to restraint in NPY-infused intact rats. All 3 groups of chronically stimulated adrenalectomized rats with clamped B had facilitated ACTH responses to restraint compared to their treatment controls. Overall food intake increased in all groups of stressed rats; however, augmented intake occurred only during the light in intact rats and equally in the light and dark in B-clamped rats. White adipose depot weights were decreased by both diabetes and cold and increased by NPY in intact rats; the decreases with cold and increases with NPY were both blunted and changes in fat stores were not significant in adrenalectomized, B-clamped rats. We conclude that: 1. diabetes- and cold-induced facilitation of restraint-induced afferent input to hypothalamic control of the hypothalamo-pituitary-adrenal (HPA) axis is opposed in intact rats by the elevated feedback signal of B secretion; 2. NPY does not induce facilitation of afferent stress pathways; 3. chronic stimulation of the HPA axis induces acute hyperresponsiveness of hypothalamic neurons to restraint provided that the afferent input of this acute stimulus is not prevented by B feedback; 4. stimulus-induced elevations in B secretion result in day-time feeding; 5. insensitivity of both caloric efficiency and white fat stores to chronic stress in adrenalectomized, B-clamped rats results from loss of normally variable B levels.     

The Assessment of College Student Need: First Step in a Prevention Response

This article introduces the assessment process, reviews selected assessment studies, and presents a unique procedure for identifying college student needs, leading to a prevention response.     

Alcohol Education Through Computer-Assisted Instruction

The author describes the application of computer-assisted instruction (CM) to alcohol education. The program, titled If You Drink, contains five modules that teach about the effects of alcohol, blood alcohol content, drinking and driving, decision making about drinking, and interactions between alcohol and commonly prescribed medications.     

Research in Counseling

This column is based on the belief that research can provide meaningful data to the practicing counselor. While individual studies may not provide sufficient data on which to act, a combination of separate research efforts or a large-scale, long-term research project does have the possibility of providing sufficient data. This column will undertake to provide that data by either reviewing the current research in a specific area or examining the results from a long-term project. The emphasis will be on implications for the counselor, so there will be little if any information on research design or statistical procedures. Readers desiring more detail about a particular study should write directly to the original author(s). Readers who desire to have the results of their research and/or innovative approaches considered for review in this column should send the material to Richard W. Warner, Jr., Counselor Education, 2054 Haley Center, Auburn University, Auburn, Alabama 36830.     

EFFECTS OF HUMOROUS ILLUSTRATIONS IN COLLEGE TEXTBOOKS

Written educational selections and cartoons drawn to illustrate different educational points were arranged to effect a factorial variation in (1) level of difficulty of educational material (easy, difficult) and (2) amount of humor (no humor, moderate humor, extensive humor). Students read one version, evaluated it on a number of dimensions, and were tested over the material. Pictorial humorous illustrations were found to have no effect on information acquisition and on motivation, positive effects on appeal, and negative effects on persuasibility.
