Understanding the three national databases on collegiate alcohol and drug use.

An overview of the three major databases used to examine alcohol and other drug use habits of American college students is provided. The databases are compared in terms of purpose, study population, subject selection, method of administration, focus, utility for institutional use, and trend analyses. The authors conclude that no one source of data is "best." Rather, the studies represent three different sources of data. Although information from these databases overlaps to some extent, each database makes a unique contribution to the field.

Measuring patient perceptions of the patient-doctor interaction. Development of the PDIS.

Patient satisfaction has been related to patient compliance, doctor-patient information exchange, and continuity of care. However, the construct of patient satisfaction is not well defined; its measurement has typically consisted of the anecdotal generation of questions that may not tap issues of concern to patients. Generally, neither reliability nor validity of the measurement instruments are considered. The present study investigated the construct of patient satisfaction and developed the Smith-Falvo Patient-Doctor Interaction Scale (PDIS), a patient satisfaction scale based on empirically derived dimensions of patient satisfaction. The project consisted of three studies. The first study involved the generation of physician behavior descriptions by 22 family practice center patients. The resultant 1540 descriptions were grouped into 80 reliable categories. In Study 2, a sample of 30 patients rated the behavior descriptions on a 9-point scale from most preferred to least preferred. Multidimensional scaling techniques were applied to the preference ratings, resulting in the identification of two dimensions: general health care delivery and inappropriate interpersonal interactions. The PDIS was then constructed from items salient to these two dimensions. Outcome of the investigation of the reliability and validity of the PDIS in a third study was quite positive.

Comparison of cardiovascular response to combined static-dynamic effort, postprandial dynamic effort and dynamic effort alone in patients with chronic ischemic heart disease.

The cardiovascular responses to combined static-dynamic effort, postprandial dynamic effort and dynamic effort alone were evaluated by upright bicycle ergometry during equilibrium-gated blood pool scintigraphy in 24 men, mean age 59 +/- 8 years, with chronic ischemic heart disease. Combined static-dynamic effort and the postprandial state elicited a peak cardiovascular response similar to that of dynamic effort alone; work load 643 +/- 156 and 638 +/- 161 vs 650 +/- 153 kg-m/min, respectively; heart rate 147 +/- 14 and 145 +/- 14 vs 143 +/- 17 beats/min; systolic pressure 195 +/- 26 and 200 +/- 25 vs 197 +/- 25 mm Hg; and rate-pressure product 286 +/- 48 and 292 +/- 55 vs 282 +/- 52. Heart rate, intraarterial systolic and diastolic pressures, rate-pressure product and ejection fraction were similar for the three test conditions at the onset of ischemia and at peak effort. The prevalence and extent of exercise-induced ischemic left ventricular dysfunction, ST-segment depression, angina pectoris and ventricular ectopic activity were also similar during the three test conditions. Direct and indirect measurements of systolic and diastolic blood pressure were highly correlated. The onset of ischemic ST-segment depression and angina pectoris correlated as strongly with heart rate alone as with the rate-pressure product during all three test conditions. The cardiovascular response to combined static-dynamic effort and to postprandial dynamic effort becomes more similar to that of dynamic effort alone as dynamic effort reaches a symptom limit. If significant ischemic and arrhythmic abnormalities are absent during symptom-limited dynamic exercise testing, they are unlikely to appear during combined static-dynamic or postprandial dynamic effort. This simplifies, the task of formulating guidelines for physical effort in patients with chronic ischemic heart disease, especially in providing "clearance" to perform avocational and vocational tasks involving combined static-dynamic and postprandial dynamic effort.

Program evaluation in sex education: outcome assessment of sexual awareness weekend workshops.

The results of an outcome assessment of a growth-oriented sex education program are reported. The evaluation project attempted to overcome flaws of existing sex education research by explicitly delineating goals and by incorporating both a rigorous experimental control group design and quasiexperimental cohort comparisons. A Sex Questionnaire (covering sexual knowledge, attitudes, and behavior) was administered to the participants of three weekend workshops at the tiem of registration and 1 month later. Overflow resistration for one workshop permitted the random selection of a no-program control group. Results supported inferences of workshop effectiveness in meeting program goals in the areas of attitude and behavior change, but not with regard to increasing sexual knowledge. Implications for development and evaluation of sex education programs are discussed.

Trait ambiguity and impression formation sufficiency tests of the meaning change model.

Two experiments tested the meaning change model's prediction for the effect of trait ambiguity on impression formation. Participants were all college students, 43 males and 29 females in Experiment 1 and 20 males and 28 females in Experiment 2. Standard impression formation tasks were used. The results revealed greater context effects for high as compared to low ambiguous traits and greater influence on description ratings for low as compared to high ambigous traits, supporting the meaning change model. When ratings of descriptions and of individual traits were clearly separated, context effects were observed only for low ambiguous traits. The implications of this finding for meaning change and information integration models of impression formation are discussed

Visual memory for place on the page.

Sixty-four Ss were asked to read a lengthy prose passage and were subsequently tested for (a) information recall, (b) memory for location of information answers; and (c) discrimination of information answers in a multiple-choice (MC) task. In aggrement with previous studies, spatial memory was highly reliable and significantly greater for correct than incorrect information answers. However, the present experiments showed that cueing Ss to a spatial test did not raise the level of spatial recall over that for a noncued group. Further, proportion of both item and spatial recall was found to increase directly with degree of visual memory for location as indexed by a five-point subjective knowledge scale. There was also a general trend for multiple-choice performance ot improve as degree of visual knowledge for an answer's true location increased. It is apparent that visually mediated spatial memory is a fundamental attribute when text material is encoded, and may be of mnemonic worth when retention of information is required.
