The paper reviews 24 case studies and experiments which assess behavior therapy for asthma or some collateral behavior management problem. The reports are examined in terms of treatment population, design, dependent variable, technique, outcome, and follow-up. Methodological and instrumentation suggestions are made for future research. 相似文献

Nondepressed human subjects were divided into seven groups. On a series of discrimination problems, a helplessness group received insoluble problems, a solvable group received contingent feedback, and a no treatment control group received no feedback. For two other groups insoluble problems were preceded by success feedback on a different task presented according to a fixed ratio (FR) or variable ratio (VR) schedule of reinforcement. Two control groups received either FR or VR schedules of success but were not examined on the discrimination problems. All groups were tested for escape/avoidance performance on a human shuttle box. Both FR and VR schedules produced an inoculation against learned helplessness; escape performance by the helplessness group was significantly worse than that of FR and VR inoculation groups. These latter groups performed similar to the solvable and three control groups. Significantly worse than that of FR and VR inoculation groups. These latter groups performed similar to the solvable and three control groups. Significantly fewer subjects in the VR inoculation group exhibited avoidance responses than their counterparts in the FR inoculation group. despite similar escape performance. The findings indicate that learned helplessness can be prevented in humans and suggest different sources of interference produced by unpredictable and uncontrollable events. 相似文献

A sexual sadist was treated by an olfactory aversion procedure for eight weeks. Pre-treatment assessment of sexual arousal showed high levels of response to sadistic stimuli as well as high arousal to non-sadistic heterosexual stimuli. In treatment the inhalation of the gas of an odoriferous chemical agent, valeric acid, was paired with slide presentations of sadistic materials while penile erection was monitored. The aversive stimulus immediately and permanently suppressed the response for the duration of treatment. In separate measurement sessions, with valeric acid absent, deviant response remained suppressed and nondeviant response was unaffected. Post-treatment reassessment revealed very low levels of response to sadistic stimuli. Follow-up sessions showed that the deviant response was absent eight months following the conclusion of treatment. 相似文献

This research was a study of the reliability of clinical judgment findings (multitrait) across three different information sources (psychometric tests, structured interview, and psychometric tests and interview). Subjects (N = 74) were middle and senior executives of Western Canadian technical companies; clinicians (N = 3) were trained and experienced industrial psychologists. The study investigated the similarity of clinical evaluation of personological characteristics (based on an 18-factor multitrait paradigm) across the three different information sources. Subjects were independently rated by a single clinician on 18 criterion factors in each of the three information source categories. Test information source categories required the administration of approximately 12 hrs of standardized psychological assessment questionnaires to each of the 74 subjects. Interview source category involved a 1.5-hr structured interview per subject. Combined condition pooled both test and interview conditions. Generalizability of the findings was maximized by the undertaking of the experiment in a natural situation thus increasing ecological validity. Statistical treatments used were designed to assess the similarity of a clinician's evaluation of a subject based on the different category of information available about that client. Convergence (intrarater reliability) indexes range from a high of .64 to a low of .05. Results indicate a varying degree of convergence of multitrait clinical ratings dependent on clinician and trait being rated. Results are discussed in terms of implications for practitioners involved in executive personnel selection. 相似文献

Employing a larger sample and a more stringent statistical criterion, this study replicated an attempt by T. G. Grandy and R. F. Stahmann (Journal of Vocational Behavior, 1974, 5, 231–239.) to test Holland's hypothesis that parents' personality types foster similar offspring personality development. The relationships between paternal and offspring personality types were consonant with the findings of Grandy and Stahmann but the role of maternal personalities remained unclear. An explanation was offered that fathers' personality types carry more weight in the development of offspring types. 相似文献

An independently conducted double-blind study providing third year follow-up data for 53 of 70 male alcoholics who served as subjects in an experiment evaluating “Individualized Behavior Therapy (IBT)” techniques is reported. In the original study, subjects were initially assigned to either a controlled drinking or non-drinking (abstinence) treatment goal, and were then randomly assigned to either an experimental group receiving IBT or a control group receiving conventional state hospital treatment oriented towards abstinence. Previously reported results showed that IBT subjects functioned significantly better than control subjects throughout the first year of follow-up. Second year follow-up results found that IBT subjects treated with a controlled drinking goal functioned significantly better than their respective control subjects on a variety of measures, including drinking behavior. Differences between IBT subjects treated with a non-drinking goal and their control subjects did not retain statistical significance during the second year of follow-up. The independently determined follow-up data showed that during the third post-treatment year, subjects in the experimental groups generally functioned better than their respective control subjects. Comparison of the controlled drinking experimental group with its control group showed the significantly better functioning of subjects in the experimental condition on a number of drinking and other life functioning measures. Comparison of the non-drinking groups indicated only one possible difference on the drinking related measures involving a trend for subjects in the experimental condition to abstain more than those in the non-drinker control group. On other life functioning measures, however, subjects in the non-drinking experimental condition showed consistent improvement over their respective control subjects. Both of the controlled drinking groups reported more controlled drinking days than the non-drinking groups throughout the third year follow-up period. 相似文献
