The advantages of selecting agoraphobic patients for treatment by group exposure according to their residential geographic neighbourhood were evaluated in terms of facilitation of ‘homework’ practice and increased social contact. Both ‘zoned’ and ‘unzoned’ groups showed gains in ability to perform hierarchy items after 11 sessions of exposure, relative to a no-treatment control group. However only zoned subjects showed significant reductions in experienced anxiety when executing such items. Self-ratings of overall phobic severity also suggested a zoned group was superior to unzoned while assessors' ratings indicated both groups as equally improved. Only zoned subjects showed a significant increase in social range. Improvements were maintained at 3-months follow-up. No effect of treatment was found on either the Zung measure of anxious mood or on social integration.These results suggest that, where practical, zoning might offer the means for desirable continuation of intensive clinic-based group treatment as well as the benefit of extending treatment into the patients' environment as in home-based treatments. Crucial levels of group cohesion might also be increased although therapists should be prepared to negotiate resistance to a socially demanding programme from patients with significant additional social phobias. 相似文献

This survey reports the results of a national survey of training programs in family therapy. Two hundred and forty-five programs responded to the survey questionnaire providing data for the development of a master list of training programs and a general assessment of the nature and magnitude of training efforts in the field. The survey included programs housed in diverse institutional settings. The data indicate the extent of growth and the increasing formalization of professional training in family therapy. A classification system is proposed for distinguishing among the major types of facilities providing family therapy training. Programs are compared in terms of the type, duration, and intensity of the training offered and the number of students enrolled. 相似文献

Client, therapist, and treatment characteristics were examined with respect to how much of the variance they could account for in a variety of outcome measures. Multiple regression analyses were used to examine relationships among each of the client, therapist, and treatment characteristics studied and the various outcome measures. For the 219 families that were treated with brief family therapy, only a relatively low amount of variance in any of the outcome measures could be accounted for. The amount of explained variance, however, varied considerably from one outcome measure to the other. When the more homogeneous groups of clients (single parents or adolescent identified patients) were considered, the amount of explained variance generally showed an increase. Different sets of client, therapist, and treatment variables accounted for the variance in these outcome measures across client groups, demonstrating both the complexities of the relationships and the relative independence of various outcome measures. New variables are suggested for future research. 相似文献

Studies of crowding in various settings have shown that individuals are aroused and frequently suffer from ill health. Several studies have shown that it is possible to successfully intervene in residential, shopping, and classroom settings to reduce the negative effects of crowding. The present laboratory experiment assessed the effectiveness of two tactics commonly used by passengers in crowded mass transit settings. Results indicated that the two tactics, reading a newspaper or talking to others, failed to reduce arousal. An explanation for the failure of these tactics is offered. 相似文献

This study examined classroom-based instruction in restauranting skills for handicapped persons. Three male students were taught each of four skill components in sequential order: locating, ordering, paying, and eating and exiting. Training was implemented in a multiple baseline design across subjects and consisted of modeling and role playing in conjunction with photo slide sequences and a simulated ordering counter. The use of a menu containing general item classes and a finger matching procedure for identifying errors in the delivery of change greatly reduced the reading and math skills necessary to enter and complete the program. Periodic probes were conducted in a McDonald's restaurant prior to, during, and up to one-year following the termination of training. In addition, two probes (overt and covert observation) were conducted in a Burger King restaurant to assess further generalization to a location different from the one depicted throughout training. Results showed that students' performance on restaurant probes improved as a result of training, generalized to novel settings, maintained over an extended period of time, and was comparable to that of a normative sample of nonretarded persons. 相似文献

Several researchers who have compared the performance of dyslexic and normal-reading children on a variety of different tasks have suggested that dyslexic children may have subtle deficits in the phonemic analysis of spoken as well as written language. Thus it is of interest to know how children who have extraordinary difficulty learning to read can perform explicity auditory-phonetic tasks. Seventeen dyslexic children (10 years of age) and a group of 17 controls were administered tests of identification and discrimination of synthesized voiced stop consonants differing in place of articulation. These were tests of the type used to study categorical perception in adults, adapted for use with young children. Significant differences between dyslexics and controls were found in both kinds of tasks; the pattern of identification and discrimination differences suggests an inconsistency in the dyslexics' phonetic classification of auditory cues. A significant relationship was found between reading level and speech discrimination. 相似文献

A system for monitoring blood pressure or other physiological variables in the unanesthetized and chronically instrumented dog is described. An indwelling catheter attaches to a pressure transducer affixed to the underside of a leather shield, which snaps onto a custom-fitted leather vest worn by the dog. The transducer cable ascends vertically through a hollow, flexible, stainless steel tether, which is attached at the lower end to the leather shield and at the upper end to a fluid and electrical swivel. The swivel is attached to an overhead counterbalanced boom assembly, which moves in concert with the dog, maintaining a constant minimal tension on the tether. The boom assembly is attached to a wall plate via a universal joint approximately 7 ft above floor level. Dogs can be maintained comfortably in this system 24 h/day over periods of months, with freedom of posture and movement, including rotational behavior. The system is economical to construct and provides versatile stimulation and record-ing capability and reliable long-term performance. 相似文献
