In relation to the open perceptual style characteristics a classification of responses to the Torrance's Circles Test provided a measure of psychosexual identification. To the initial stimulus inner-spaced and outer-spaced responses can be interpreted as feminine and masculine styles of information processing. The observations were validated by the Mf scale of the MMPI. Masculine women gave fewer inner-space responses than masculine men, and feminine men gave more inner-space responses than feminine women.  相似文献

A two-stage epidemiologic study conducted between 1986 and 1988 in the southeastern United States investigated family and psychosocial predictors of obsessive compulsive disorder (OCD) and subclinical OCD in young adolescents. In the first stage, a life-event schedule and a family adaptability and cohesion scale were administered to a community sample of 3,283 adolescents. In stage two, the Schedule for Affective Disorders and Schizophrenia in School Age Children and the Children's Global Assessment Scale were administered to 488 mother-child pairs. In multivariable models family cohesion was the only significant correlate of OCD (odds ratio=0.95, 95% confidence interval 0.91–0.98). Gender, race, age, socioeconomic status, guardian status, adaptability, undesirable life events and desirable life events were not found to be significant predictors of OCD in models adjusting for cohesion. Note of the above variables were significantly associated with subclinical OCD. However, separate analyses of the 41 individual life events indicated seven specific events were significantly associated with OCD or subclinical OCD. These findings are at odds with the theory that overinvolvement of family members is a risk factor for OCD, though an association with overly rigid family structure cannot be eliminated based on these data. Further exploration of family characteristics is warranted.  相似文献

In a study designed to maximize the effectiveness of treatment by allowing participants to select the target of treatment, 40 depressed older adults were randomly assigned to a waiting-list control condition or to conditions in which the target of treatment was either chosen or assigned. All participants received self-management therapy and the choice was between changing behavior or changing cognition. It was found that individually administered self-management therapy was effective in treating depression for older adults. There were no differences in outcome between versions of self-management therapy that targeted behavioral or cognitive change. Among those who completed treatment, there were no differences in outcome between those who received a choice and those who did not. Individuals who were given a choice of treatment options, however, were less likely to drop out of treatment prematurely.  相似文献

31 17-35 yr.-old men (15 college athletes and 16 nonathletes) performed three dead-lifts with and three without grunting, the order of which was randomly assigned. No differences were found across the grunting trials and grunting did not affect maximal force production. Grunting does not appear to increase maximum force production significantly during a large muscle group, force output activity (isometric dead lift).  相似文献

In this work, the tactual information transmission capabilities of a tactual display designed to provide stimulation along a continuum from kinesthetic movements to cutaneous vibrations are assessed. The display is capable of delivering arbitrary waveforms to three digits (thumb, index, and middle finger) within an amplitude range from absolute detection threshold to about 50 dB sensation level and a frequency range from dc to above 300 Hz. Stimulus sets were designed at each of three signal durations (125, 250, and 500 msec) by combining salient attributes, such as frequency (further divided into low, middle, and high regions), amplitude, direction of motion, and finger location. Estimated static information transfer (IT) was 6.5 bits at 500 mseC., 6.4 bits at 250 mseC., and 5.6 bits at 125 msec. Estimates of IT rate were derived from identification experiments in which the subject’s task was to identify the middle stimulus in a sequence of three stimuli randomly selected from a given stimulus set. On the basis of the extrapolations from these IT measurements to continuous streams, the IT rate was estimated to be about 12 bits/seC., which is roughly the same as that achieved by Tadoma users in tactual speech communication.  相似文献

An ongoing longitudinal community study (N = 375) examined childhood risks and later adult impairments associated with 1-year Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) diagnoses of major depression during the transition to adulthood. Risks from birth to age 9 were reported by mothers, participants, and teachers. Teacher-reported hostility at age 6 predicted later depression. At age 9, self-perceptions of anxiety/depression, unpopularity, familial rejection, and abuse were potent risks. For men, neonatal and childhood health problems predicted later depression. For women, risks included family constellation, parental death, and poor academic achievement at age 9. Men and women who were depressed at age 18, age 21, or both demonstrated extensive psychosocial impairments in early adulthood, including poor overall functioning, interpersonal and behavioral problems, low self-esteem, and suicidality.  相似文献

This study examined the nature of cognitive reactivity to mood changes in formerly depressed patients. Patients who recovered either through cognitive-behavior therapy (CBT; N = 25) or through pharmacotherapy (PT; N = 29) completed self-reported ratings of dysfunctional attitudes before and after a negative mood induction procedure. In response to similar levels of induced sad mood, PT patients showed a significant increase in dysfunctional cognitions compared with patients in the CBT group. To evaluate the effects of such cognitive reactivity on the subsequent course of depression, follow-up analyses reassessed 30 patients several years after initial testing. Results indicated that patients' reactions to the mood induction procedure were predictive of depressive relapse. These findings argue for differential effects of treatment on cognitive reactivity to mood induction and for the link between such reactivity and risk for later depressive relapse.  相似文献

Since the terms of the health policy debate in the United States and Canada are largely supplied by biomedicine, the current “crisis” in health care is, in part, a product of biomedical rhetoric. In this essay, three metaphors widely identified as being associated with biomedicine—the body is a machine, medicine is war,and medicine is a business—are examined with a view to the ways in which they influence the health policy debate, not only with respect to outcomes, but also with respect to what can be argued at all. The essay proposes that biomedical language itself be foregrounded as the constitutive material of public discourse on health policy.  相似文献

This paper examines the relationships between insurance coverage, need, and mental health services in a community-based sample of 1,015 youths who were 9, 11, and 13 years old at the beginning of the study. They were followed over a two-year period. A strong measure of need based on a standardized diagnostic interview was available and repeated over three annual waves. Data on service use was collected quarterly across two years. Major findings included: (a) high need (serious emotional disturbance [SED]) was strongly related to use of any mental health services; (b) services use was much more likely to occur with public (Medicaid) insurance coverage than either private or no insurance; (c) considerable unmet need was observed even for youths with SED; (d) school-based mental health services potentially substituted for professional mental health services; and (e) there was little unnecessary use of mental health services in the low need group. The major policy implication of these findings is that the regulation of insurance benefits should be based on level of need, rather than on arbitrary limits which are likely to either reduce the probability of or appropriate amount of care for youths who most need mental health services.  相似文献
