Helms (1984) presented a model to explain the influence of Black and White racial identity development on counseling interactions. The purpose of this study was to examine her hypothesis that specific combinations of racial identity attitudes contribute to qualitatively different counseling process and outcome or relationship types. 相似文献

This study investigated the relationship between intergenerational family relationships and Frankl's concept of meaning in life. Intergenerational family relationships were measured by the Personal Authority in the Family System Questionnaire (PAFS-QE) by Bray, Williamson, and Malone. The meaning in life variables were measured by the Life Attitude Profile-Revised (LAP-R) by Reker. This quantitative study, using the BMDP Statistical Package (Dixon, 1990), correlated the scores on various subscales from both instruments, resulting in seven statistically significant relationships. The findings, although modest, suggest the existence of a relationship between these two theoretical areas.This article is based in part on the first author's doctoral dissertation at Texas Woman's University.A copy of the PAFS-Q may be obtained from: James H. Bray, PhD, 5510 Greenbriar, Houston, TX 77005. A copy of the LAP-R may be obtained from: Gary Reker, PhD, Trent University, Psychology Department, Peterborough, Ontario Canada K9J 7B8. 相似文献

This exploratory study sought to determine whether selected religion-related factors differentiated between 86 patients with
obsessive compulsive disorder (OCD), 73 patients with panic disorder, and 292 patients with other psychiatric (non-anxiety)
disorders. A standard history questionnaire was used to obtain information from patients concerning religion of origin, involvement
in religious activities, religious conflict, and perceived religiousness of parents. It was found that the percentage of patients
who reported experiencing religious conflict was significantly higher for the OCD group than for the other two groups. Other
findings suggested associations between Catholicism and OCD and between Protestantism and panic disorder, but further research
is needed to clarify these relationships.
This article is based on a paper presented at the 98th annual convention of the American Psychological Association, Boston,
August 1990. 相似文献

A variety of abnormal sensory/motor behaviors associated with electrical discharges recorded from the bilateral brainstem were induced in adult WKY rats by mechanical (electrode implants) and DC electrical current stimulations and by acute and chronic administration of cocaine. The electrode implant implicated one side or the other of the reticular system of the brainstem but subjects were not incapacitated by the stimulations. Cocaine (40 mg/kg) was injected subcutaneously for an acute experiment and subsequent 20 mg/kg doses twice daily for 3 days in a chronic study. Cocaine generated more abnormal behaviors in the brainstem perturbation group, especially the electrically perturbated subjects. The abnormal behaviors were yawning, retrocollis, hyperactivity, hypersensitivity, "beating drum" behavior, squealing, head bobbing, circling, sniffing, abnormal posturing, and facial twitching. Shifts in the power frequency spectra of the discharge patterns were noted between quiet and pacing behavioral states. Hypersensitivity to various auditory, tactile, and visual stimulation was present and shifts in the brainstem ambient power spectral frequency occurred in response to tactile stimulation. These findings suggest that the brainstem generates and propagates pathological discharges that can be elicited by mechanical and DC electrical perturbation. Cocaine was found to activate the discharge system and thus induce abnormal behaviors that are generated at the discharge site and at distant sites to which the discharge propagates. Cognitive functions may also be involved since dopaminergic and serotonergic cellular elements at the brainstem level are also implicated. 相似文献

Recently, debate about the distribution of scarce organs for transplantation has focused on whether patients should have the right to place themselves on waiting lists at several transplant centers, thereby gaining an advantage over other potential recipients. This article explores the social and ethical issues raised by multiple listing, contrasting policies adopted at the national level with those implemented in New York State. It concludes by examining the implications of the debate for broader questions about entitlement and access to health care. 相似文献

This study of 20 ‘white-collar’ workers aged 20–30 measured motivation, enjoyment and access to various categories of experience in both work and leisure, and examined their relationship with psychological well-being on a number of dimensions. The method used a short questionnaire, psychological scales and the innovatory ‘experience sampling methodology’ (ESM) where respondents answer questions in a diary on the receipt of a signal from a pre-programmed watch or radio pager eight times a day for 1 week. The results show, in line with other studies, that intrinsic motivation in daily life is correlated with happiness but that, not previously reported, when motivation at work is examined both extrinsic motivation and instances where a person had to do the activity but did not wish to be doing something else, i.e. ‘positive motivational change’, are correlated with positive aspects of psychological well-being, while instances where a person wanted to do the activity but wished to be doing something else, i.e. ‘negative motivational change’, correlated with negative aspects. The results also show that enjoyment in both work and leisure correlates with aspects of psychological wellbeing; and that macro ‘flow’ experiences, where high skills and high challenges are perceived as equal, are enjoyable and interesting and come primarily from work. The study also shows that categories of experience considered important for psychological well-being and deemed to come primarily from work can be obtained in leisure. The results are discussed in the context of person—situation interactions and processes, and it is advocated that these should be studied in a variety of samples. 相似文献
