This group of studies describes the development of a 200 item, self-report, 4-point true-false inventory (Coolidge Axis II Inventory [CATI]) to assess personality disorders according to the criteria established in the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-III-R]; American Psychiatric Association, 1987). The 13 personality disorder scales of the CATI had a mean test-retest reliability of .90 and a median internal consistency (Cronbach's alpha) of .76. There was a 50% concordance rate with clinician's diagnosis for 24 personality disordered patients. The median concurrent validity (raw score sums) between the CATI and the Millon Clinical Multiaxial Inventory-II for the 13 personality disorder scales was .58. Preliminary studies also support the reliability and validity of Depression, Anxiety, and Brain Dysfunction scales.  相似文献

Are changes over time in the quality of a woman's job associated with changes in her psychological distress? Do family roles moderate these relationships? We addressed these questions using longitudinal data from a 2-year 3-wave study of a stratified random sample of 403 employed women who varied in occupation, race, partnership, and parental status. After estimating individual rates of change for each woman on each of the predictors and the outcome, we modeled the relationships between family role occupancy and change in job-role quality on the one hand, and change in psychological distress on the other. Among single women and women without children, as job-role quality declined, levels of psychological distress increased. Among partnered women and women with children, change in job-role quality was unrelated to change in psychological distress.  相似文献

Two experiments examined the influence of anger and retaliatory motivation on memory for negative material. In the 1st study, 60 male undergraduates memorized words with positive, negative, and neutral semantic connotations. It was found that angered men who expected to retaliate against their provocateur recalled more negative words than other words, and more than Ss in all other affect and evaluation conditions. Angered men in the nonretaliation condition displayed no differences in negative word recall. The 2nd experiment investigated memory for details of a provoking experience. Angered men who expected to retaliate more accurately recalled the details of their provocation, but whether they were given the retaliation information before or after provocation had no bearing on memory for these details. Results are discussed in terms of a motivation-based selective generation hypothesis for the relationship between anger and memory.  相似文献

In two experiments, key pecking of pigeons was maintained by a variable-interval 180-s schedule of food presentation. Conjointly, a second schedule delivered response-dependent electric shock. In the first experiment, shocks were presented according to either a variable-interval or a nondifferential interval-percentile schedule. The variable-interval shock schedule differentially delivered shocks following long interresponse times. Although the nondifferential shock schedules delivered shocks less differentially with respect to interresponse times, the two shock schedules equally reduced the relative frequency of long interresponse times. The second experiment differentially shocked long or short interresponse times in different conditions, with resulting decreases in the relative frequency of the targeted interresponse times. These experiments highlight the importance of selecting the appropriate level of analysis for the interaction of behavior and environment. Orderly relations present at one level of analysis (e.g., interresponse times) may not be revealed at other levels of analysis (e.g., overall response rate).  相似文献

We evaluated the efficacy of the Addiction Potential Scale (APS) and the Addiction Acknowledgement Scale (AAS), two new scales designed to assess substance abuse problems with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), in samples from settings different from those used in their development. Results replicate earlier findings that both scales discriminate between psychiatric and substance abuse samples and do so more effectively than other substance abuse scales designed for use with the MMPI and carried over to the MMPI-2. Results also suggest that APS may be more resistant than AAS to response distortion.  相似文献

This paper describes the way in which a hospital stay functions as a period of liminality. The opportunities for transformation inherent in such an experience are examined, with special attention given to the role of the hospital chaplain as the ritual leader who can help facilitate the movement through liminality and into wholeness.Ann Hallstein the M. Div. from Union Theological Seminary in May 1992 and expects to be ordained in the United Church of Christ.  相似文献

This study examined the effect of demographic variables and intellectual factors on the Short-term Memory Test. Subjects were 20 patients neurologically diagnosed as brain-damaged. There was only one significant correlation between Verbal IQ and the Short-term Memory Test. Demographic variables of age, education, and sex did not correlate significantly with scores of the Short-term Memory Test.  相似文献

This paper summarizes a number of studies in which the validity of the Employee Reliability Inventory, a preemployment screening instrument designed to assess the likelihood of reliable and productive workplace behavior, was examined. Criterion-related studies compared the scores of a broadly diverse group of job applicants with those obtained from an array of criterion and comparison groups, for whom there was documented evidence of reliable or unreliable behavior. Criterion-related evidence indicates that the six scales are effective in differentiating a variety of criterion groups with unreliable behavior from a number of different job applicant comparison groups. Construct-related evidence for the validity of an emotional adjustment scale is reported as well. The issue of response distortion in preemployment inventories is discussed, and data are reported which indicate that scores on all six scales appear to be functionally free from the potentially confounding effects of response distortion. These results are consistent with the original validation and cross-validation findings, which supported the validity of the six scales when assessing the likelihood of reliable behavior in a population of job applicants.  相似文献

As the analyst makes the correct interpretations of resistance in the opening phase of an analysis, the patient begins to feel understood, often for the first time. This feeling allays anxiety and depressive affects, and the patient comes to experience the analyst as a soother. These initial exchanges may lay the foundation for a positive transference which acts as a buffer against turbulent transferences. In some patients this positive transference develops rapidly, often with prompt symptom remission. In others--children as well as adults--the analyst must persistently interpret defensive regressions before a stable, positive transference can emerge. In either case, in order to avoid the analysis of conflict, some patients become resistant to the analysis of the wish to be soothed. Many of these patients have had a childhood filled with traumatic parental stimulation or rejection. Two clinical accounts illustrate these contentions.  相似文献

This study investigated the performance of 38 learning disabled and 16 emotionally impaired children and youth on the Wechsler Intelligence Scale for Children--Revised, Wide Range Achievement Test--Revised, and Minnesota Percepto-Diagnostic Test--Revised. The ages of the children ranged from 8.4 to 16.7 years (M = 12.4, SD = 3.6). The findings suggest that discriminate functional analysis may be useful in the differential diagnosis process. Implications for clinicians are discussed.  相似文献
