Smokers and nonsmokers were compared on three aspects of academic achievement. Although exactly the same percentage of smokers
and nonsmokers passed the first-year university examination, smokers obtained significantly higher marks. Similarly, smokers
achieved significantly higher marks in their final year examinations in comparison with nonsmokers. Finally, a comparison
of the tutorial essay marks of the smokers and nonsmokers again showed that smokers obtained significantly higher marks than
nonsmokers. These data are consistent with the idea that ambitious students adopt smoking in the belief that it will help
them study and sustain concentration. 相似文献

This paper discusses an exploratory investigation concerned with the long range questions: How does group psychotherapy help patients? and How can psychiatry residency programs best train residents to treat patients in therapeutic groups? Group psychotherapy has come to be accepted in its own right as a decisive contribution to the study of and relief of emotional disorders. As a component of comprehensive psychiatric services it is indispensable. However, while its clinical value has been demonstrated, its scientific validity has not. A Group Process Inventory has been developed by the author and has been utilized for the past two years by psychiatric residents in recording the process of their therapeutic groups in a teaching hospital mental hygiene clinic. The preliminary use of this recording as a clinical-teaching instrument has proven effective. This inventory is being revised to serve as a research instrument. 相似文献

Suicide and rurality in urban society 总被引:3,自引:0,他引:3
Recent findings suggest that suicide increases with rurality, but research on rural suicide leaves many questions unanswered. This study specifies problems of community organization as a reason for expecting a positive effect of rurality on the suicide rate. A multiple regression analysis of county data shows that rurality has a substantial positive effect and is, in fact, the best predictor of the suicide rate among several variables selected from the previous literature. Additional research is needed to test the interpretation that rurality contributes to an incomplete, fragmented form of community organization which influences the suicide rate by disrupting primary relationships. 相似文献

The author focuses on the trend in the family therapy field toward an expanded view of families in the context of their social environments. Within this broader eco-system perspective attention is given to individual-family-social network interrelations with implications for the family therapist.An earlier version of this paper was presented at the American Association for Marriage and Family Therapy, Dallas, Texas, October 29, 1982. Appreciation is expressed to Alice Lynn for her comments and suggestions on an earlier draft of this paper. The author has also benefitted from discussions with Douglas Sprenkle on paradigms and contexts. 相似文献

In the literature on cotherapy, little attention has been focused on maximizing the effectiveness of two therapists working in tandem with families and couples. While cotherapists may at times share their ideas and feelings with their clients, and after the therapeutic session exchange views between themselves, generally little interaction occurs between them during the session. In this paper, a case is presented for more active interactions between cotherapists during the session, in order to expedite and facilitate change and growth in their clients. Anecdotal examples are provided to illustrate the approach. 相似文献

The authors conducted two full-scale network assemblies for the family network of a suicidal adolescent. Findings from the clinical follow-up and telephone interviews with 21 of 65 participants revealed benefits for the index family and the network members who participated in the meetings. A ripple effect in which the participants' own personal networks improved was also demonstrated. Benefits included resolution of a suicidal crisis, better understanding of depression and family stress, more adaptive responses to depression and suicidal risk, and improved personal relationships. No casualties from this intervention were discovered. This report is intended to stimulate future, more systematic outcome studies. 相似文献

Markedly different profiles on the Jones Irrational Beliefs Test (IBT) were obtained from a sample of mental health professionals, of clients in psychotherapy, and of women college students, and the differences were clearly interpretable. In a second study those with high (more irrational) scores on each scale were compared with those with low (more rational) scores on indicators of physical (psychosomatic) illness. On five of the scales as well as for the total score the more irrational groups had significantly more physical symptoms of illness. And, finally, tension headache frequency was found to be related to the total IBT score.It is argued that these findings offer further evidence for the validity of the IBT, and its use in research and clinical practice is encouraged. A reporting booklet for bibliotherapy use with clients is described.Paul J. Woods, Ph.D., co-editor of this journal, is an associate fellow of the Institute for Rational-Emotive Therapy, a professor of psychology at Hollins College, and is engaged in private practice in Roanoke, Virginia. 相似文献

Four adult male rats were each placed for three hours daily into an apparatus that provided individual compartments for six separate location-defined responses. The available responses consisted of: (1) the opportunity to turn off room lighting, producing darkness; (2) the opportunity to view a female rat; (3) the opportunity to turn off white noise; (4) the opportunity to drink; (5) the opportunity to eat; and (6) "other," representing time in the hallway between compartments. Each subject underwent a series of conditions characterized as an A-B-A-C-A design. Manipulations consisted of the removal of a low-probability response (darkness) and of a high-probability response (escape from noise) in a counter-balanced manner across subjects. The dependent measure for all subjects was the percentage of total session time spent in each compartment. Four predictive rules concerning the redistribution of behavior after response restriction were tested, including the constant-ratio rule, equal time redistribution, the most probable alternative, and the sequential-dependency rule. The results indicate no support for any of the four predictive rules and suggest that empirical assessment of restriction effects is necessary in reinforcement studies involving temporally extended responses. 相似文献

The meaning of "phi" in Max Wertheimer 's 1912 article on seen movement (the publication of which marks the beginning of Gestalt psychology) and the import of the article itself were topics of a report in this Journal. The claims made in that report are questioned here, and a different interpretation of phi and the original article is offered. 相似文献
