The concept of codependency constitutes a controversial but, in our view, eminently researchable area of clinical concern. Following a perspective on the evolution of the concept, we summarize the currently dominant view that codependency is a personality syndrome closely akin to addictive love. We then present an alternative point of view that focuses on the characteristics of codependent relating rather than the characteristics of the codependent person, arguing that codependency may be either endogynous or exogynous. Recent efforts to develop valid measures of codependency as a personality predisposition and as a set of relationship characteristics are discussed, followed by the conclusion that the two assessment approaches are complementary rather than contradictory.We gratefully acknowledge the assistance of Mike Dewald, Karin Parker, and Pam Quinn of the United Recovery Center, Grand Forks, ND, in some of the data collection.  相似文献

Archaeologists employed in governmental positions often deal with issues that produce conflicts between their professional duties to their employer, their ethical responsibilities to the resource, and their obligations as established by legislation. The paper examines some of the conflicts imposed on governmental archaeologists by each of these systems but focuses on the conflicts imposed by federal legislation and regulations on governmental archaeologists, using “Kennewick Man” as an example. This is a revised edition of a paper written for the symposium: “Ethics in Science: Special Problems in Anthropology and Archaeology,” organized by Merrilee Salmon; 1998 Annual Meeting of the American Association for the Advancement of Science (Philadelphia, February 15, 1998). The original paper was in a more conversational style as befitting a discussion atmosphere. Revisions, comments, and opinions are entirely the author’s.

Most of the publicized work on scientific ethics concentrates on establishing professional norms and avoiding misconduct. The successful communication of science is the responsibility of all involved in the process. In one study, the increased incidence of autism and other social developmental disorders in males was investigated by examining individuals with Turner's syndrome (XO females). In the national newspaper this became "Genetic X-factor explains why boys will always be boys". The steps by which a study on developmental disorders, published in a highly prestigious journal, was transformed into an article in the science section which 'explained' the socially expected gender-based behavior of genetically normal children are fascinating and, unfortunately far too typical. The scientists wrote an excellent article that has just one sentence at the end that hesitantly suggests that the findings might, with further study, have some relevance to understanding normal behavior. The general interest article in the front of the journal gave a good account of the research, but suggested more strongly that there could be an in-built biological dimorphism in social cognition. This was misrepresented in the press as proof of gender differences that "undermines the trend towards sexual equality", and both illustrates cultural bias and provides fodder for feminist critiques of science. The study has been made to appear to be biased in favor of justifying the social structure of society, and yet it was the translation from the scientific study to national news that produced this transformation to biased genetic determinism. It is poor communication of the actual science, coupled with a lack of skepticism on the part of the public, that contributes to such a misapplication of science. Scientists should resist the urge to generalize their results to make them more compelling. The science community should not allow misconstructions of scientific facts to go unchallenged. Journalists, for both the scientific publication and the newspaper, should resist the inclination to embellish the finding with social significance that is not present. For their part, readers must be doubly skeptical of any finding that appears to underwrite any current social hierarchy. We are all responsible for a communication and interpretation of science that is as accurate and socially responsible as possible.  相似文献

Informed citizen advisory boards are vital to the operation of community mental health programs. In order to provide relevant educational experiences, a continuing education program conducted a survey of the self-judged level of knowledge of a sample of board members in a large city. The sample consisted of 57 respondents representing 16 of 19 city mental health centers and the three federally funded community health centers located in the city. The results indicated areas of strength and weakness. Also, knowledge assessments differeed in relation to years of experience on advisory boards. Several suggestions are made about designing curricula for mental advisory boards.  相似文献

There is now a growing body of research examining developmental dyslexia in different languages and writing systems. The phonologically transparent Persian orthography is normally transcribed with two distinct spellings, words spelled with vowels (letters) transcribed as a fixed part of the spelling (transparent) and words spelled with vowels (diacritics) omitted (opaque). This peculiarity of Persian would enable one to examine the impact of transparency, as well as the possible psychological factors associated with verbal punishment in Persian schools on the development of reading and spelling. Twenty-nine Persian children (22 male and 7 female) classified as being developmentally dyslexic (mean age 9.4, SD?=?1.4) were compared with 49 unimpaired male children (mean age 9, SD?=?1.3) on two main aspects of reading Persian opaque and transparent spellings, namely: Spelling and word naming. The results showed an expected impairment on all aspects of reading between unimpaired and children with dyslexia. However, performance of both groups of participants was impaired when performing tasks with opaque as opposed to transparent spellings. There was also a strong correlation between the recorded number of times the dyslexic child was verbally punished and the number of errors on the spelling and naming of transparent and opaque words. These results are supportive of the impact of spelling transparency, as well as psychological variables as factors in the development of reading and spelling.  相似文献

One longstanding hypothesis in the research of depression among Chinese populations is that they tend to express depressive symptoms in somatic terms, which, in turn, prevent them from seeking assistance from mental health services. This study aimed to examine the manifestation of depressive symptoms and its relationship to help‐seeking attitudes among Chinese college students. The Chinese Beck Depression Inventory‐II (BDI‐II; Beck, Steer, & Brown, 1996 ) and the Attitudes Toward Seeking Professional Psychological Help: Shortened Form (ATSPPH‐SF; Fischer & Farina, 1995 ) were administered to 1039 Chinese college students in a private university in Taiwan. Factor ratio scores analyses revealed that Chinese college students generally emphasized somatic complaints compared to cognitive‐affective complaints in expressing depressive symptoms. Probably‐depressed Chinese students (BDI‐II scores?16), however, placed significantly less emphasis on somatic symptoms than did nondepressed students. Additionally, multiple regression analyses showed that while Chinese students with elevated BDI‐II scores were less likely to seek professional psychological help, neither somatic nor cognitive‐affective symptoms were correlated with their attitudes toward seeking and avoiding professional psychological help. These findings seem to run counter to the common assumption that Chinese people tend to express depression in somatic terms and that somatic complaints help to explain their reluctance to seek professional psychological assistance. The current results suggest that Chinese students with elevated depressive symptoms readily acknowledged and expressed cognitive‐affective symptoms of depression and they were likely to distance themselves from professional psychological help. However, somatic symptoms did not explain their reluctance to utilize mental health services.  相似文献

This study uses a multitrait, multimethod (MTMM) approach to investigate the genetic and environmental etiologies of childhood deviant peer affiliation (DPA) and problem behavior (PROB). The variability of genetic and environmental estimates by agent and method is also examined. A total of 77 monozygotic and 72 dizygotic twin pairs and each twin's close friend were assessed. The informants included parents, teachers, and twins, and the methods involved questionnaire reports and coder ratings of videotaped dyadic interactions between each twin and their close friend. Twin intraclass correlations and univariate models attributed DPA and PROB to genetic, and shared and nonshared environmental effects. Parameter estimates differed by rater and method, however. Results accentuate the imperative to attend to method effects inherent in MTMM behavioral geneticresearch.  相似文献
