This study investigated the relationships between attitudes toward the male role, gender role conflict factors, and depression in 401 college men. Results indicated that all four of the gender role conflict factors were significantly correlated with depression. Hence, more traditional men may experience a compounded risk comprising increased likelihood of depression coupled with decreased use of counseling services. Both directions for future research and the implications for counselors and student services are discussed.  相似文献

While a great deal of behavior analytic research has focussed on studying current contingencies, the amount of work done in the area of conditioning history is spotty, at best. Weiner (1964, 1969) conducted history research with human subjects, but little has followed in either the human or the nonhuman literature. Some direction can also be found in the literature studying the effects of conditioning on drug effects (e.g., Barrett, 1977; Urbain, Poling, Millam, & Thompson, 1978). However, "behavioral history" or "conditioning history" has not been a fully-developed area within behavior analysis. It is suggested that empirical work on history effects might have implications for (a) better understanding human-nonhuman behavioral differences and similarities, (b) clinical applications, especially where clients are resistant to behavioral change, and (c) theoretical assumptions in behavior analysis in relation to both basic and applied concerns.  相似文献

We examined the comorbidity of bulimia and personality pathology among college women. Subjects included women (n=23) meeting DSM-III-R criteria for bulimia nervosa (bulimics), women (n=23) who reported binge eating but did not fulfill the criteria for bulimia nervosa (binge eaters), and women (n=23) who did not binge eat (normals). The subjects completed an assessment battery consisting of the Personality Disorders Examination and the SCID as well as the Beck Depression Inventory, the Rosenberg Self-Esteem Index, and measures of impulsivity and self-defeating tendencies. Fourteen of 23 bulimics (61%) met criterion for a personality disorder using DSM-III-R Axis II criteria. In comparison, 3 of 23 (13%) binge eaters and 1 of 23 (4%) normal subjects received an Axis II diagnosis. Borderline and self-defeating diagnoses were the predominant personality disorders in 96% of the bulimics exhibiting clinically significant personality pathology. Bulimics also exhibited significantly more depression, impulsivity, and self-defeating behavior and lower self-esteem than binge eaters and normals. The findings are discussed within a conceptual framework that posits an interaction between personality pathology and restrained eating.  相似文献

A survey of Human Resource practitioners' perceptions of pre-employment screening procedures was conducted. The results indicated differences between tests in terms of perceived accuracy and offensiveness, as well as other attributes. Regression analyses suggested that beliefs about validity, the number of other companies using these procedures, perceived offensiveness of the test, and ease in passing the test were important factors in the willingness to use a particular test. Conversely, perceptions regarding the discriminatory impact of the test and the cost of using the test generally were not related to willingness to use the test. Limitations of this study, which was primarily exploratory, are noted.  相似文献

If mental state can influence the external world, or if alternate dimensions of reality are accessible only in certain mental states, then important aspects of the universe are unknowable with current scientific tools. Near-death studies suggest that both those conditions may occur. Thus the exploration of NDE-like phenomena requires a radically new scientific paradigm.  相似文献

Much family therapy writing has focused on work with discrete presenting problems in circumscribed clinical practice settings. This paper takes a broader focus of poor families which do not fit easily into the one-hour therapy schedule, in the context of the powerful forces of politics and economics. If the prevailing political attitudes and economic realities are ignored, direct practice with families may fail to meet them at their point of experience. Examples of political views, and therapeutic and research thinking which do not pay attention to these aspects, are used to highlight the author's point of view.  相似文献

Problems with regard to the analysis of argumentative partly discourse arise from definitorial disconformity. In this article, Informal argument is taken as the primary definition to study the basic structure of argument from a fragment of an Agatha Christie novel. Bilmes' account of the notions of Formulation (F) and Decision (D+/D-) are adapted to describe the relations of opposition which are displayed in informal argument. The minimal structure of argument is represented by the formula F/D-/D-, in which F is a speaker's personal composition of a fact, the first D- is the disconfirming uptake of it by another speaker and the second D- is the completing disconfirming uptake by the initial speaker. Some of the speaker's possibilities to initiate an argument by expressing a Formulation are explored, as well as the social and cultural norms which play a role in argument-initiation and the concepts of win and loss.  相似文献
