Sex difference trends in completed suicide   总被引:1,自引:0,他引:1  
The recent suicide literature increasingly has contained statements suggesting that the differences in completed suicide between the sexes are lessening. A compilation of official suicide data for 1933-1980 verifies such a trend from the 1950s through 1971. However, increased differences (as measured by the ratio of male to female rates) were consistently observed from 1971 to 1980. These trends were found for data for the nation, for whites and nonwhites, for numbers of suicides, for crude rates, and for age-adjusted rates. Decreased sex differences were obtained for those 35-44, 45-54, 55-64, and for 65+ years of age, but increased sex differences were observed for those aged 15-24 and 25-34. Possible explanations for these findings are presented.  相似文献

This article examines the social, historical, empirical, and legal issues surrounding the concept of joint custody which has now been accepted in over half of the states. Early results in joint custody states suggest that joint custody awards prove satisfactory to parents and children provided that the parents are able to cooperate in childrearing activities and that they live in close geographic proximity. General recommendations and guidelines for joint custody are presented.  相似文献

Age-related differences in the pleasantness of chemosensory stimuli   总被引:2,自引:0,他引:2  
Modest decrements in both taste threshold sensitivity and, more recently, suprathreshold sensitivity have been associated with the aging process. The present study was designed to investigate the existence of changes in preference for various concentrations of single tastes and of the same single tastes in more complex chemosensory mixtures. In this study, 300 participants from three different age groups (18-26, 32-45, over 65) rated for pleasantness four concentrations of sodium chloride, sucrose, and citric acid presented in both aqueous and beverage bases. Results showed significant effects of age, stimulus background, stimulus, concentration, and of several interactions, and they suggest that elderly subjects find salt and sugar pleasanter at higher concentrations than younger subjects do.  相似文献

Homosexuals, bisexuals, and heterosexuals were compared on self-reported love preferences and ideals. In general, the three groups tended to agree on ideal characteristics of love objects, love relationships, and love related beliefs. Nevertheless, the groups differed significantly on preferences and beliefs related to love-object sex, residential proximity, ethnic background, physical intimacy, freedom from feelings of jealousy, sexual fidelity, emotional intimacy, and the importance of religious or legal acknowledgment.An early version of this paper was presented at the Annual Meeting of the National Council on Family Relations, in San Francisco, October 1984, Journal Series No. 2973 of the Hawaii Institute of Tropical Agriculture and Human Resources.  相似文献

The deleterious effects of occupational stress on worker health and well-being have been described in numerous reports for a wide range of work groups. Work overload (and underload), deadline pressures, role Stressors, underutilization of abilities, and physical discomfort have been identified as work factors associated with increased stress symptom reporting. The relationship between work stress and accident/injury occurrences is less clearly documented, although scattered reports in the literature suggest a contributory role for stress in the accident process. In this article, data linking stress to unsafe work behavior are reviewed and a model is proposed wherein accidents can arise from impaired worker capabilities (e.g., slower reaction time) brought about by stress symptom activity (e.g., anxiety). The potential usefulness of stress management training (SMT) for shortcircuiting the stress/accidents cycle by alleviating stress symptoms is discussed in light of recent empirical research.Portions of this article were presented at the Third Annual Scientist/Practitioner Conference in Industrial/Organizational Psychology, Virginia Beach, Virginia, October, 1982.  相似文献

This article describes the underlying theory, development, and initial validation of the Safety Locus of Control Scale. This paper-and-pencil inventory assesses levels of safety consciousness among employees. Initial research suggests that the inventory is a reliable predictor of employees' accidents, injuries, and driving safety. Potential uses for the inventory are discussed, and future research is suggested.This article is from a paper presented at the Annual Conference of Human Resource Management and Organizational Behavior, Boston, Massachusetts, November 18–20, 1985.  相似文献

Integration is one of the most prevalent contemporary themes in the field of family therapy. This discussion proposes a process-based model of integration which transcends theoretical content. A brief review of integrative efforts in the field of marriage and family therapy is followed by an exploration of issues related to theoretical content. A model for understanding the personal process of integration is developed which articulates a five stage process of integration. Finally, after a brief character development to illustrate the different stages, some initial implications for a process-based model of integration are explored.David J. Moultrup, MSW, LICSW, is in private practice in Arlington, Massachusetts.  相似文献

In this study of 37 pre-therapy and 23 matched control families who never sought family therapy, father-child welfare affect and mother-child emergency affect were significantly higher in the control families. Control families were found generally to express more Welfare and Emergency emotion. Affective expression between parents did not significantly differentiate the groups.This study has been supported by Grant No. MA-4510 of the Medical Research Council of Canada and was presented at the annual meeting of the Canadian Psychiatric Association, Ottawa, Ontario, Canada, September 1983. The authors wish to express their thanks to Toby Schwartz, Harriet Gold-Kaats, and Terry Tannenbaum-Dascal, who acted as coders and research assistants; Joseph Beltempo, BSc, who helped in the statistical analysis; and James Robbins, PhD, who gave much valuable advice.  相似文献

The purpose of the present study was to develop an alternative paradigm for measuring irrationality and conduct a preliminary reliability and validity analysis of a self-report scale so constructed. From considering some basic theoretical assumptions in Rational-Emotive Therapy (RET), anemotive paradigm for item-construction was formulated and utilized to develop a 12-item self-report scale for measuring irrationality (SVO-12). A different scale (SVC-12), based on acontent approach, was also developed. These two irrationality scales and a scale for measuring psychopathology were then administered to a group of 199 undergraduate students. Statistical analyses provided empirical support for the reliability and validity of both approaches. Of the two irrationality scales in question, however, the one based on the emotive paradigm (SVO-12) seem to be the most promising.  相似文献
