There is a need to Africanise family therapy so as to serve the interest of local communities. Western approaches to family therapy have been accused of being irrelevant to African contexts. They are seen as forming part of a dominant scientific knowledge which invalidates local folk and cultural psychologies and thereby continuing a historical tradition of oppressive colonial power relations. This paper aims at archaeologising and evaluating such criticism by situating family therapy within different fields of knowledge that have emerged historically and are currently co-existing in Africa. The advantages and disadvantages of dominant family therapy approaches in African contexts are explored by focussing on power relations between different knowledges in Africa. It is argued that many global narratives of family therapy offer congenial companionship to many local African narratives, but that family therapists should pay more attention to local spiritual and political narratives so as to attain more legitimacy and validation by local communities.  相似文献

Cystic fibrosis (CF) is one of the most commonly inherited recessive disorders in U.S. Caucasians, with a carrier frequency of approximately 1 in 29. Genetic counseling and CF mutation analysis has traditionally been offered to the affected patient and his/her extended family, in keeping with policy statements from professional organizations (ASHG, NSGC, ACOG). The target population for CF testing and counseling may be evolving after the release of the 1997 National Institutes of Health Consensus Statement, Genetic Testing for Cystic Fibrosis, which recommends that CF screening be offered to all preconceptional and pregnant couples. Genetic counseling for CF is complicated by reports of polymorphisms in the CF gene that are associated with symptoms that do not meet the diagnostic criteria for CF, such as bilateral congenital absence of the vas deferens, bronchiectasis, and idiopathic pancreatitis. To aid genetic counselors with these issues, this review explores the symptoms of CF, patient management, gene function, genetics, genotype/phenotype correlation, and genetic counseling issues.  相似文献

A 10-year naturalistic study of 313 patients who entered treatment for unipolar depression and a community comparison group of 284 nondepressed adults was conducted. We compared life stressors, social resources, personal resources, and coping among patients who were remitted (N = 76), partially remitted (N = 146), or nonremitted (N = 91). Compared with the controls and the remitted patients, the partially remitted and nonremitted patients consistently experienced more life stressors and fewer social resources, were less easygoing, and relied more on avoidance coping. A less easygoing disposition, fewer close relationships, and more reliance on avoidance coping were associated with higher odds of experiencing a course of partial remission or nonremission. In addition, more depressive symptoms and medical conditions predicted nonremission.  相似文献

The Program Environment Scale (PES) was developed for use with clients of community-based programs for the severely mentally ill. It is intended to fill the gap in available tools for assessing clients' perceptions of program functioning as it affects their quality of life in a program. Formal pretests were conducted with 121 clients at 12 randomly selected programs near Washington, DC. The final field test used a revised form (29 domains; 129 items) with 221 clients in 22 programs selected randomly throughout the U.S., including Clubhouse, day treatment, psychosocial rehabilitation, and social club programs. Twenty-three subscales met at least five of eight psychometric criteria for internal consistency and discriminant validity. A 24th subscale was retained because of its substantive importance. Successful subscales cover program atmosphere and interactions (program cares about me, energy level, friendliness, openness, staff-client and client-client respect, reasonable rules, availability of positive physical contact, protection from bad touch, staff investment in their jobs, and confidentiality), client empowerment/staff-client equality (program and treatment empowerment, egalitarian space use), and service components (support for paid work, work importance, emergency access, family activities, housing, public benefits, community activities, medications, substance abuse, and continuity). Subscale validity is indicated by associations of specific service offerings with scores on scales measuring client perceptions of those services, and by an ability to differentiate among program models (i.e., Clubhouses, day treatment programs, and psychosocial rehabilitation programs look different from each other). Subscale scores were not influenced by client characteristics (gender, race, age, diagnosis, number of hospitalizations, length of time in program). The final scale has 97 items and takes about 25 minutes to complete. The PES succeeds in measuring different aspects of programs as clients perceive them. In the programs we visited, directors felt the PES covers the important things they want to know about how clients perceive their program. The PES should become a useful tool both for researchers interested in how client responses to programs may influence their therapeutic outcomes, and for practitioners interested in improving their clients' program experiences and/or increasing convergence of staff and client views of their program.  相似文献

Twenty-six children with attention deficit/hyperactivity disorder (ADHD) participated in a double-blind trial consisting of 2 consecutive weeks each of placebo and methylphenidate (M = 26.92 mg/day = 0.78 mg/kg/day). As expected, stimulant therapy resulted in moderate weight loss, increased somatic complaints, and teacher and parent reports of reduced inattentiveness, aggression, and oppositionality. In both phases of the trial, patients were tested in a choice reaction time task assessing two aspects of the task that presumably affect response selection: response frequency (ratio of targets/nontargets = 25/75 vs. 50/50) and stimulus sequence (alternations vs. repetitions). Both manipulations yielded expected results on performance and event-related potentials (ERPs). Stimulant treatment increased accuracy and speed among younger children and curtailed variability of reaction time for the sample as a whole. However, methylphenidate did not affect ERPs. In combination, the results imply that the enhancement of performance by methylphenidate does not involve the demands of response selection examined in this study.  相似文献

Participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors is reviewed. We begin by tracing the origins of and defining both participatory action research and self-help/mutual aid. In so doing, the degree of correspondence between the assumptions/values of participatory action research and those of self-help/mutual aid for psychiatric consumer/survivors is examined. We argue that participatory action research and self-help/mutual aid share four values in common: (a) empowerment, (b) supportive relationships, (c) social change, and (d) learning as an ongoing process. Next, selected examples of participatory action research with psychiatric consumer/survivor-controlled self-help/mutual aid organizations which illustrate these shared values are provided. We conclude with recommendations of how the key values can be promoted in both the methodological and substantive aspects of future participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors.  相似文献

This study investigated factors that have previously been implicated in male sexual aggression towards women, using a structural equation modelling approach to assess their relative influence on sexually coercive behaviours in young Singaporean men. Variables were classified under three major headings: childhood experience, personality, and attitudes facilitating violence. Non-sexual aggression against women was included in order to investigate its relationship to sexual aggression as well as its own causal antecedents. Results suggest that sexual and non-sexual aggression have different antecedents, and confirm the primacy of sexual variables (sexual experience, child sexual abuse) as antecedents to sexual aggression. Contrary to the hypothesis that sexual aggression is primarily aggressive in motivation, belligerence exerted only indirect effects on sexual aggression. Attitudinal variables (e.g. attitudes supportive of sexual aggression) contributed modestly to sexual but not to non-sexual aggression. Antisociality exerted indirect effects on both sexual aggression (via sexual experience and acceptance of interpersonal violence) and on non-sexual aggression (via belligerence). Parental violence contributed exclusively to non-sexual aggression. Finally, some cross-cultural differences in sexually coercive behaviour are highlighted.  相似文献

Latin and Asian-Pacific immigrants are the fastest growing new-comer groups in the U.S. contributing to 85% of immigration totals. New immigrants experience multiple barriers to accessing genetic counseling resulting from cultural, linguistic, financial, and educational factors as well as having unique perceptions on health, illness, reproduction, and life as a whole. In addition, new immigrants lack familiarity with Western medical practices as well as genetic risk and available interventions. We provided perinatal genetic services to 2430 clients, mostly new immigrants of Latin and Asian-Pacific descent over a period of 6 years. Counseling aides sharing the clients' cultural backgrounds were employed. A study assessing the efficacy of cross-cultural education regarding advanced maternal age risk and amniocentesis was implemented and linked to a database containing demographic and clinical information. Practical observations relating to cultural beliefs in the two groups relevant to perinatal genetic counseling were made.  相似文献
