The differential importance of weight and body image among college men and women

Among a sample of American college students, body image and the degree of desired weight change were associated with academic self-rankings, with social and psychological well-being, and with the development of eating difficulties. The effects of body image and desired weight change on eating disorders were generally found to be greater for women than for men, and their effects on student self-rankings of academic ability, social, and psychological traits were more pervasive for women than for men. The less attractive a woman perceived herself to be and the more weight she wanted to lose, the greater was her overall sense of academic, social, and psychological impairment. Women who had poor body images and who desired to lose weight were more likely to report eating difficulties.     

Temporal manipulation of stimulus patterns using the Apple II: Tachistoscopic and part presentation

A technique is described in which line-drawn pictures can be rapidly interlaced, allowing for sequential part presentation or tachistoscopic presentation on the Apple II. This is accomplished using a two-stage process in which the pictorial stimuli are converted into machine code data files and then used to create a rapidly changing display consisting of two or more line drawings. The latter stage could be accomplished in less than 2 msec but is limited by the frame time of the monitor (17–20 msec).     

IBM PC Tachistoscope: Text stimuli

Due to cost, speed, and flexibility, the IBM PC and compatibles are good computers for laboratory use. Outlined here is a program that allows a computer from this class of machines to be used as a tachistoscope. The example given is for visual half-field presentation and can be easily modified for other presentation paradigms.     

Developing probability limits for longitudinal physiological data

The objective of this study was to determine what amount of change in heart electrophysiology is necessary to yield a significant difference between a baseline condition and an experimental treatment condition. In a single-subject longitudinal design, a modification of at test was applied to baseline data, and the performance levels for both .05 and .01 probability levels were obtained. It was concluded that it is both ethically sound and physiologically safe to permit a subject in this type of experiment to physiologically respond at levels that would reach both the .05 and the .01 levels of significance.     

Cognitive determinants of lactate-induced anxiety

The effects of lactate infusion on subjective mood change were studied in two differently instructed groups, in a double-blind, placebo-controlled, cross-over study. Ss who were told that infusions would produce anxiety reported a significant change in the expected direction after lactate but not after glucose. Ss who were told that infusions would produce a state of pleasant excitement showed no change after either infusion. The possible role of cognitive parameters in experimentally-induced anxiety is discussed.     

Prevalence of DSM-III conduct and adjustment disorders for adolescent psychiatric inpatients

The prevalence of DSM-III conduct and adjustment disorders in two adolescent psychiatric facilities, both located near large U.S. cities, was investigated. Overall, 31.6% of the adolescent inpatients were conduct disordered while 12.5% were adjustment disordered. The conduct disorders were primarily "aggressive" subtypes suggesting that this characteristic may influence hospitalization and diagnostic decisions. Such data on prevalence assists future treatment planning, allowing anticipation of case loads.     

Coitally active university students: sexual behaviors, concerns, and challenges

The past fifteen years, in particular, have seen a major increase in the extent to which both adolescents and young adults are engaging in sexual intercourse. While several studies call attention to the increasing incidence among college/university students, the concomitant shifts in the sociopsychological realms of sexuality are also important dimensions which impact upon sexual concerns of youth. Hence, the purposes of this study are to examine the behaviors, attitudes, and concerns of students who have engaged in coitus, as well as any changes they seek in their sex lives. The sample consisted of 123 never-married male and 205 never-married female undergraduate students from a state university. The data were obtained by utilizing an anonymous questionnaire administered to volunteers during regular university classes. Among the coitally active, 67.4% of males were psychologically satisfied after their first sexual experience, but only 28.3% of females. In contrast, 80.9% of males and 28.3% of females reported current psychological satisfaction with their sexual experiences. Significant differences between genders focused on male dissatisfaction with infrequent opportunities for sexual intercourse, lack of variety of sex partners, and insufficient oral-genital stimulation, whereas females expressed concerns relating to lack of stimulation to their breasts, painful sexual intercourse, lack of orgasm during sexual intercourse, and feelings of guilt and fear. An increasing awareness of current sexual behaviors, attitudes, and concerns of university students can help family life educators to meet student needs as they react to changes in interpersonal relationships, families, and society.     

Health needs and concerns of male adolescents

Lifestyle factors established within the family help determine health-care functioning. Adolescents first may be challenged to meet their own health needs as freshmen in college. A 153-item questionnaire was utilized to examine concerns in the areas of alcohol and other drug use, auto safety, weight and dieting, smoking, sexuality, coping and stress, and selection and utilization of health-care services. One hundred fifty-nine male college students responded. Major problems with alcohol use, auto safety, weight control, stress and sexuality were identified. Positive lifestyle factors that were strongly supported included regular exercise, nonsmoking, regular medical and dental checkups, and the development of some support systems to cope with stress. Health-care services designated by respondents to meet their own needs were significantly different from those services they pointed out as needed for their peers.
