While the long-term effects of combat trauma on veterans have been studied extensively, its impact on veterans' wives has yet to be investigated. This study examined the implications of combat-induced psychopathology--wartime combat stress reaction (CSR) and current posttraumatic stress disorder (PTSD)--in a sample of 205 wives of Israeli combat veterans of the 1982 Lebanon war. Results show that both CSR and PTSD were associated with increased psychiatric symptoms in the wives. In addition, current PTSD was particularly found to contribute to impaired social relations among veterans' wives in a broad range of contexts, from inner feelings of loneliness, through impaired marital and family relations, and extending to the wider social network. Implications of these findings for treatment and further research are discussed.  相似文献

I presented a substantially different version of this paper at the 1991 American Philosophical Association Central Division Meeting. William L. Rowe commented. The paper in its present form has profited considerably from Rowe's comments.  相似文献

ABSTRACT A taxon is a nonarbitrary class whose existence is conjectured as an empirical question, not a mere semantic convenience. Numerous taxa are known to exist in nature and society (chemical elements, biological species, organic diseases, geological strata, kinds of stars, elementary particles, races, cultures, Mendelizing mental deficiencies, major psychoses, vocations, ideologies, religions). What personality types, if any, occur in the nonpathological population remains to be researched by sophisticated methods, and cannot be settled by fiat or "dimensional" preference. The intuitive concept of taxonicity is to be explicated by a combination of formal-numerical and causal criteria. Taxometric methods should include consistency tests that provide Popperian risk of strong discorroboration. In social science, latent class methods are probably more useful than cluster algorithms.  相似文献

This article provides a review of the implications of analytic psychology for pastoral care and the caregiver. Four areas of Jung's thought are examined: (1) his mode of treatment, (2) the process of individuation, (3) his theory of personality types, and (4) his concept of synchronicity. We suggest that Jung's system of thought contains a rich reservoir of insight for the enrichment of pastoral care.  相似文献

The validity of the Threat Index was examined in a study of 42 students and 15 HIV+ clients. When completing the Threat Index, subjects rate the self and death on 30 bipolar adjectives. A count is made of the number of times the same adjective poles are used to describe the self and death. Uses of the same poles are called matches, while uses of different poles are called splits. The Threat Index is based on the assumption that splits indicate threat. Analysis showed that neither splits nor matches were usually threatening and that neither was necessary or sufficient for the experience of threat. These results did not support the validity of the Threat Index.  相似文献

Two cases of Gilles de la Tourette syndrome from India are presented. The symptomatology of Tourette syndrome is the same as that documented in western populations which suggests biological factors in the aetiology of the syndrome.  相似文献

This review summarizes research concerning the relation between paternal factors and child and adolescent psychopathology. When compared with mothers, fathers continue to be dramatically underrepresented in developmental research on psychopathology. However, findings from studies of children of clinically referred fathers and nonreferred samples of children and their fathers indicate that there is substantial association between paternal characteristics and child and adolescent psychopathology. Findings from studies of fathers of clinically referred children are stronger for fathers' effects on children's externalizing than internalizing problems. In most cases the degree of risk associated with paternal psychopathology is comparable to that associated with maternal psychopathology. Evidence indicates that the presence of paternal psychopathology is a sufficient but not necessary condition for child or adolescent psychopathology.  相似文献

One hundred adults and 30 children completed questionnaires to investigate fear of dogs. Dog fearful adults asked to recall the origins of their fear reported classical conditioning experiences more frequently than vicarious acquisition or informational transmission. Overall, however, there was no difference in the frequency of attacks reported by the fearful and non-fearful groups. Significantly more fearful than non-fearful adults reported little contact with dogs prior to the onset of their fear which suggests that early non-eventful exposure to dogs may prevent a conditioning event from producing a dog phobia. Most adults reported that their fear began in childhood, and dog fear were more frequently reported by children than by adults. In the aggregate, however, dog-fearful adults and children differed in several ways; children were more likely than adults to report having received warnings about dogs, but also to recognize the potential attractiveness of a friendly dog. Unlike dog-fearful children, dog-fearful adults reported many other fears in addition to their fear of dogs. A better understanding of fear of dogs in adults may depend on discovering why some dog-fearful children, but not others, apparently lose their fear of dogs as they become older.  相似文献
