D M Amoroso  E E Ware 《Adolescence》1986,21(81):191-204
Although there is extensive literature on the home environment as a socializing agent and on the perception of self and others, research relating home environment variables to adolescents' perception of themselves and others is not common. The present study, using a survey of 480 students, attempts to define and relate these two domains. Factor analyses of 16 semantic differential scales generated three dimensions--evaluation, understandability, and potency--for specifying attitudes toward self, parents, and certain external authority figures (teachers and police). In addition, factor analysis of 20 variables relating to adolescents' perception of their home environment suggested five factors: (1) extent of punishment, (2) amount of chores at home, (3) perceived parental control, (4) absence of parents, and (5) parents' attitude toward authority figures. Controlling for sex and age, these home environment factors were found to account for sizable portions of variance in certain components of the person perception domain. Particular relevance for several of these factors are discussed.  相似文献

Health needs and concerns of male adolescents   总被引:1,自引:0,他引:1  
W J Pinch  M Heck  D Vinal 《Adolescence》1986,21(84):961-969
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.  相似文献

Factors related to eating disorders in young adolescent girls   总被引:1,自引:0,他引:1  
The objective of this study was to identify factors related to eating disorders in young adolescent girls. Three hundred eighty-five girls who were attending a career conference at a midwestern university completed the Eating Disorder Instrument (EDI) along with a biographical data sheet. The EDI is designed for the assessment of psychological and behavior traits common in eating disorders. While 81% of the young subjects were assessed to be within the range for ideal weight or were underweight, 78% preferred to weigh less. Only 14% were satisfied with their current weight. Findings for each of the subscales used revealed significant differences among the girls based on intact versus broken family; subjects' actual and preferred weight; whether the family ate meals together; average grades; age and grade in school; fathers' occupation; future career plans; place of residence; and feelings toward their mothers.  相似文献

Recognizing people seen in events via dynamic "mug shots"   总被引:1,自引:0,他引:1  
This study examined effects of an event and dynamic mug shots on facial recognition. Witnesses saw either a film of a liquor store holdup staged by six perpetrators, slides of the same targets, or freeze-framed views from the filmed event. Slides of different facial views of targets among 12 foils, or dynamic 180 degrees mug shots of the same men, or multiple static views were administered 24 hr later in yes-no recognition tests. Recognition (d') was poorer for the same men seen in the event than in slides, but better for dynamic than for static mug shots. Nondynamic event characteristics were responsible for poor recognition of people seen in events, whereas dynamic aspects of facial transformations, not multiple views, seemed responsible for the superiority of dynamic mug shots. The implications of these results for issues of ecological validity of traditional face recognition methodology and for static feature models vs. dynamic transformation models of face recognition are discussed.  相似文献

MARY DECHESNAY  D.S.N.  R.N.  C.S. 《Family process》1986,25(2):293-300
The relationship between basic research, theory, and clinical work with families is conceptualized during a discussion of Jamaican family structure and the application of change theory to a clinical case of depression in a Jamaican woman. It was found that three types of family structure are prevalent in Jamaica. The European ideal of a patriarchal-patrifocal structure creates problems for working-class Jamaicans. General system theory provides support for a different model. Change theory is applied to resolve the paradox created by the European model.  相似文献
