Compared mental health characteristics of island Puerto Ricans to three groups from the Los Angeles Epidemiologic Catchment Area Study: Mexican American immigrants, U.S.-born Mexican Americans, and Non-Hispanic whites. The Diagnostic Interview Schedule was used to obtain both diagnostic and symptom scale information about affective disorders, alcohol abuse/dependence, somatization, phobic disorder, and psychotic disorder. Mexican American immigrants had the fewest mental health problems of all groups. Puerto Ricans had more somatization disorder, but less affective and alcohol disorders than U.S-born Mexican Americans or non-Hispanic whites. Results are considered in the light of selection factors, relative disadvantage of groups and methodological problems. This research was supported by grants MH36230 and MH45763 from the National Institute of Mental Health, and made use of data from the Los Angeles site of the Epidemiologic Catchment Area Program, which is a series of five epidemiologic research studies performed by independent research teams in collaboration with staff of the Division of Biometry and Epidemiology of the National Institute of Mental Health. The NIMH principal collaborators were D. Regier, B. Locke, W. Eaton and J. Burke. The NIMH project officers were C. Taube and W. Huber. The principal investigators and coinvestigators from the five sites were Yale University: J. Myers, M. Weissman, G. Tischler; Johns Hopkins University: M. Kramer, E. Gruenberg, S. Shapiro; Washington University: L. Robins, J. Helzer; Duke University: D. Blazer, L. George; University of California at Los Angeles: M. Karno, R. Hough, J. Escobar, A. Burnam, D. Timbers.  相似文献

The primary goal of this retrospective study was to assess parental report of current sleep disorders in school-aged attention deficit disorder (ADD) children, as well as recalled sleep problems from when the children were infants (0–12 months) and toddlers (1–3 years). Results of a sleep questionnaire completed by mothers of 48 ADD children and a comparison group of 30 patients with school problems indicate that ADD children were perceived to have significantly more sleep problems and that these problems had onset in infancy. Specific items in the questionnaire which were increased included latency to sleep onset of more than 30 min at least 3 nights per week, fatigue upon awakening, and recall of nightmares. Pediatric clinicians should be alert to possible sleep disorders in children suspected of attention disorders and should consider sleep hygiene measures as a component of treatment.  相似文献

The death and transfiguration of career-and of career guidance?   总被引:3,自引:0,他引:3  
The predominant understanding of career in the industrial era has focused on progression within hierarchical work organisations. With the move into a post-industrial era, the possibility of such careers is rapidly receding. The concept of career, however, has always been broader than this, and other aspects of it are now claiming increased attention. They focus more upon individual experiences in terms of development in learning and work throughout life. The role of career guidance in relation to such experiences is potentially of much greater social significance. A number of implications for career guidance provision and practice are discussed.  相似文献

Mainstream career theories have been criticised for their scanty conceptualisation of the environment that influences individuals' careers. There are few foundations upon which to build an appropriate conceptualisation of the dramatically changing environment of career today. The implications of Pepper's contextualist world hypothesis are discussed. Compared with orthodox approaches, the world as seen from this perspective is as different as the Internet is from a library; its understanding of the environment, and indeed career, is also significantly different. The contextualist perspective upon career research, theory and practice is outlined and the possibility of its adoption in the mainstream of the career field is explored  相似文献

Medin, Goldstone, and Markman (1995) recently described a series of parallel effects in similarity and choice. They suggested that similarity and choice are related in a nontrivial way such that choice may entail a similarity judgment to an explicit or constructed ideal. In this paper, the correspondences between similarity and choice were investigated with respect to a phenomenon in similarity known as thecoincidence effect. In coincidence (pronounced “coincide-ence”), two items that match on one dimension but have a large difference on another dimension receive a higher similarity rating than do two items that have only modest differences on both dimensions. We conducted five experiments in order to examine commonalities between similarity and choice processes with respect to coincidence. Four types of tasks were given: similarity ratings, desirability ratings, forced choice similarities (which of two items is most similar to a target), and forced choice preferences (which of two items one would prefer, given a target). We found a main effect for ratings as opposed to forced choices, with ratings showing greater coincidence effects than did choices. Similarity measures tended to produce more coincidence than did preference measures. The overall pattern of results suggests the presence of dimensional weighting processes sensitive to task characteristics and operating somewhat differently for similarity and decision making.  相似文献

This study attempted to assess the inductive explanation of language acquisition. It was predicted that inductive acuity, operationally defined by reference to Kagan's concept of Reflection-Impulsivity, would facilitate syntactic and semantic development. Results indicated that children who are superior inductors scored higher on semantic tests, but not on syntactic tests. It was suggested that distinct learning strategies may be involved in the acquisition of syntax and semantics. Various theoretical implications of these findings for models of language encoding were discussed. Suggestions for subsequent research were offered.  相似文献

Correlations between the WAIS-R Verbal, Performance, and Full Scale IQs, WAIS-R subtest scaled scores, and Wide Range Achievement Test Reading, Spelling, and Arithmetic standard scores were computed for a sample of 60 patients at a V.A. medical center who were referred for routine psychological evaluation. The Full Scale IQ and Verbal IQ yielded large correlations with the three achievement area standard scores (rs of .60 to .76). However, Performance IQs correlated moderately with reading and spelling scores (rs of .41 and .42), but a larger correlation obtained with arithmetic scores (r = .66). The results support the concurrent validity of the WAIS-R.  相似文献
