Spiritual experiences are often associated with health crises, with little information about the structure of the experience. A taxonomic analysis was conducted on data from a group of healers, unveiling a structural model of spiritual experience comprised of three domains: circumstances, manifestation and interpretation. Circumstances included the aspects of setting, situation, and timing. Manifestation incorporated the modes of awareness and the phenomena of the experience. Components of interpretation included personal meaning and congruence with social norms. The examples reflected the orientation of the study population. Further research could examine the applicability of the taxonomy to other religious or spiritual orientations and may assist in clinical assessment of spiritual experiences.Diane Wind Wardell, Ph.D., R.N.C., H.N.C., C.H.T.P./I., and Joan C. Engebretson, Dr.P.H., R.N., H.N.C., are Associate Professors in the School of Nursing at the University of Texas Health Science Center at Houston.

Objectification theory explicates a model in which women are socialized to view their own bodies as objects to be evaluated. In the current study, we used a 2 (self-objectification condition: swimsuit versus sweater)?×?2 (gender) factorial design to examine whether body-related thoughts continued after women were removed from a self-objectifying situation. Results showed that, compared to participants in the other three groups, women in the self-objectification condition listed more body-related thoughts during a free response task given after they had re-dressed. The amount of shame experienced during self-objectification mediated the relationship between self-objectification condition and lingering body-related thoughts. This study adds to the understanding of how the process of self-objectification works to maintain women’s focus on their appearance.  相似文献

Women with pelvic floor disorders use many adaptations in an attempt to minimize symptoms and enhance the quality of their lives. Existing condition-specific measures fail to capture the extent or impact of these adaptive behaviors. The present paper seeks to extend the women’s health literature and expand the registry of available measures to assess pelvic floor disorders by: 1) documenting the steps taken in the development and initial validation of the Measure of Adaptations for Pelvic Symptoms (MAPS); and 2) describing the added value of incorporating the patient’s voice in the instrument development process through in-depth focus groups. The rigorous process used to develop the measure (i.e., literature review, clinical experts, anecdotal patient reports, telephone-administered pilot study, and focus groups with female patients) is described. Analysis of the focus group data yielded eight important adaptation themes used to further refine the MAPS: disclosure, seclusion, being prepared, planning, clothing considerations, sexuality, order and intensity, and outlook. Specifically, focus group participants confirmed the use of sanitary pads and limiting food and beverage consumption. Women did not endorse keeping a jar or commode nearby. Discussions yielded important modifications to items about restroom use, clothing preferences, “survival kits” and “informal” pessary use. Participants described social isolation and preparations for sexual relations that led to new items. This study confirmed the value of incorporating women’s voices in the questionnaire development process through in-depth focus groups. The process revealed important patient experiences and led to significant refinements of the final measure.  相似文献

Although there has been keen interest in the association among measures of sensory function and cognitive function for many years, in general, measures of sensory function have been confined to one or two senses and measures of threshold sensitivity (acuity). In this study, rigorous psychophysical measures of threshold sensitivity, temporal gap detection, temporal order identification, and temporal masking have been obtained, in hearing, vision, and touch. In addition, all subjects completed 15 subtests of the Wechsler Adult Intelligence Scale, 3rd edition (WAIS–III). Data were obtained from 245 adults (18–87 years old) for the WAIS–III and for 40 measures of threshold sensitivity and temporal processing. The focus in this report is on individual differences in performance for the entire data set. Principal-components (PC) factor analysis reduced the 40 psychophysical measures to eight correlated factors, which were reduced further to a single global sensory processing factor. Similarly, PC factor analysis of the 15 WAIS–III scores resulted in three correlated factors that were further reduced to a single global cognitive function factor. Age, global sensory processing, and global cognitive function were all moderately and significantly correlated with one another. However, paired partial correlations, controlling for the third of these three measures, revealed that the moderate correlation between age and global cognitive function went to zero when global sensory processing was controlled for; the other two partial correlations remained intact. Structural models confirmed this result. These analyses suggest that the long-standing observation of age-related changes in cognitive function may be mediated by age-related changes in global sensory processing.  相似文献

This study investigated strategy and performance differences between right-handed boys and girls on a mental rotation task. Based on predictions from Casey and Brabeck's (1990) theory of sex differences, the study was also designed to identify a target group of right-handed girls with the optimal combination of genetic and environmental factors (high math/science achievers with nonright-handed immediate relatives). They were predicted to show strategies and performance more similar to those of the boys than to those of both the low math/science achieving girls and the high math/science girls with all right-handed immediate relatives (predicted to have the nonoptimal genotype). Strategy preference was measured using selective interference, whereby subjects solved mental rotation items concurrently with either verbal or visual-spatial interference tasks. Group comparisons were made on the amount of decrement in mental rotation performance as a result of the two types of interference tasks. This provided a basis for comparing the groups on the use of visual-spatial or verbal strategies on the mental rotation task. The boys: (1) did not show a significant advantage over the girls on the mental rotation items, but (2) did depend more on visual-spatial strategies than the girls, and (3) depended less on verbal strategies than the girls. The target girls: (1) outperformed the low math/science achieving girls on the mental rotation items and did not show a significant advantage over the other high math/science group, (2) depended more on visual-spatial strategies than both the other two groups of girls, and (3) depended less on verbal strategies than the low math/science girls, while showing no significant difference compared to the nonoptimal high math/science girls. Examining within-group differences, the boys preferred visual-spatial strategies, while the girls in both the nontarget groups preferred verbal ones. However, for the target girls, no within-subject strategy differences were found. The present findings support the theory that, like the boys, the target girls depend more on visual-spatial strategies than do other girls. It is possible that the target girls use a combination of visual-spatial and verbal strategies when solving mental rotation tasks.  相似文献

Self-objectification is the act of viewing the self, particularly the body, from a third-person perspective. Objectification theory proposes numerous negative consequences for those who self-objectify, including decreased performance through the disruption of focused attention. In the current study, we examined whether women in a state of self-objectification were slower to respond to a basic Stroop color-naming task. Results showed that regardless of the type of word (color words, body words, or neutral words), participants in a state of self-objectification exhibited decreased performance. This study lends further evidence to objectification theory and highlights the negative performance ramifications of state self-objectification.  相似文献

Serotonergic abnormalities have been reported in both autism and epilepsy. This association may provide insights into underlying mechanisms of these disorders because serotonin plays an important neurotrophic role during brain development--and there is evidence for abnormal cortical development in both autism and some forms of epilepsy. This review explores the hypothesis that an early disturbance in the serotonin system affects cortical development and the development of thalamocortical innervation, and is a potential mechanism, common to autism and pediatric epilepsies associated with cortical dysplasia. An argument is made that cortical malformation leads to abnormalities of thalamocortical connectivity, and that serotonin plays a critical role in this process. Finally, a role for altered metabolism of the serotonin precursur, tryptophan, in both epilepsy and autism is discussed.  相似文献

Many studies have compared the demographic and clinical characteristics of patients with and without borderline personality disorder (BPD), but there is limited knowledge on differences within the population of borderline patients. One potential index of heterogeneity is disorder severity. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we examined whether the severity of borderline personality disorder, as measured by the number of criteria present, is associated with co-morbidity of Axis I and Axis II diagnoses, as well as demographic factors and psychosocial functioning. Two thousand three hundred psychiatric outpatients were interviewed with the Structured Interview for DSM-IV Personality (SIDP-IV). Approximately ten percent (n = 237) of the patients were diagnosed with BPD, and they were divided into four groups based on the number of DSM-IV criteria met, 5 (n = 89), 6 (n = 70), 7 (n = 46), and 8 or 9 (n = 32). There were greater rates of drug use disorders and comorbid Axis II disorders, as well as a greater number of suicidal gestures, in patients meeting seven or more BPD criteria. There were no significant differences between the groups in the number and specific rates of other co-morbid Axis I disorders, other measures of psychosocial functioning, or demographic correlates. Sub-typing of borderline patients by the number of criteria met provides a limited explanation for heterogeneity within BPD patients.  相似文献

Genetic Counselors (GCs) spend years learning about genetics and practicing counseling techniques in classroom environments. From the learner perspective, teaching may seem straightforward: provide appropriate information, develop tests or assignments and submit grades. When asked to teach for the first time, however, clinicians suddenly realize that there is a lot more to education than standing in front of a class and talking. This article introduces clinical educators to strategies and learning principles that help make the teaching/learning process more interesting and successful for faculty and students alike. The instructional concepts presented here are useful across the entire spectrum of learning situations; a 1 hour discussion with a lay audience, a 3 hour workshop at a professional meeting, a 15 week graduate course, or a series of courses culminating in an advanced degree. The article offers suggestions for writing course competencies, selecting instructional approaches, embedding learning engagement options, leveling course content and choosing evaluation strategies.  相似文献
