50 patients suffering from terminal mammary cancer and visceral metastases received chemotherapy, and in addition half of them received psychotherapy, while half did not. A lymphocyte count was undertaken seven times in all, once before initiation of chemotherapy, the others after six applications of the therapy. As hypothesized, the 25 women who received psychotherapy lived longer and had significantly higher lymphocyte counts on Occasions 5, 6 and 7 than did the 25 women who did not receive psychotherapy. Of the types of psychotherapy employed, a specially designed form of behaviour therapy was significantly more helpful than dynamic psychotherapy in prolonging life.  相似文献

This article provides a comprehensive review of the research on smoking and body weight. The relationships between smoking and body weight are evaluated in 70 cross-sectional and longitudinal investigations. The mechanisms responsible for differences in body weight are discussed, the weight-related issues that promote smoking behavior are reviewed, methods for reducing postcessation weight gain are summarized, and future research directions are proposed. A proposed working research model for studying the relationship between smoking, energy balance, and weight gain is offered. It is concluded that smoking and body weight relationships are closely related and pose significant challenges for smoking researchers.  相似文献

Many factors go into a choice of a therapeutic focus: the patient's psychopathology; the therapist's training, countertransference reactions, and ideological beliefs; and, importantly, a decision about what seems most amenable to treatment and change. As a theory, self psychology describes one aspect of the paranoid process; as such, it is an incomplete theory that complements rather than invalidates more classical theories. As a technique, however, it suggests a style and focus conducive to working with paranoid patients, one that is markedly supportive, nonconfrontational, yet also interpretive. In this context, it must be remembered how difficult it is to treat paranoid patients psychotherapeutically, much less to keep them in treatment. The strategies discussed above do not wholly replace other dynamic approaches (e.g., counterprojective techniques), nor are they universally applicable. Some patients may be more amenable than others. However, the techniques provide a very supportive framework that may help the therapist to be more available to and in contact with the paranoid patient. More broadly, this paper's application of self psychology to the theory and therapy of the paranoid disorders further illustrates the practical utility of this approach. Attention to the narcissistic developmental line, interpersonal selfobject relationships, intrapsychic conflicts and deficits, and empathic immersion in the patients's world are important adjuncts to the psychotherapy of paranoid patients. Rather than an either/or dichotomy, the principle of overdetermination suggests a both/and relationship between self psychology and traditional theory, such that the self psychological approach complements rather than contradicts the classical psychoanalytic theory. The vicissitudes of the self simply add another perspective or vantage point from which to understand and respond to the patient, one which has perhaps more applicability for preoedipally disordered patients.  相似文献

An organizational field study involving 95 civil service employees examined the ways these individuals coped with the stressful events of their daily living. Lazarus' cognitive-phenomenological analysis of psychological stress provided the theoretical framework. Subjects indicated on Lazarus' Ways of Coping Checklist those coping thoughts and actions used in the specific encounter described as stressful. As hypothesized, individuals experiencing higher diastolic blood pressure were more likely to cope using strategies characterized by wishful thinking, avoidance, and minimization of threat than were individuals exhibiting lower blood pressure. Implications from both an individual and organizational perspective are discussed.  相似文献

Within an evolutionary context two subtypes of limbic system dysfunctioning are compared: (1) the previously proposed limbic psychotic trigger reaction, in which nondrive motivated homicide is triggered by a specific individualized external stimulus, which evokes a brief-lasting active reliving of past (moderately) stressful, frequently repeated ("kindled"?) situations. The brief-lasting out-of-character homicidal episode with flat affect is typically associated with first-time formed or unformed hallucinations of various modalities and with overactivation of the autonomic nervous system. There is no (noticeable) loss of consciousness, enabling the patient's full recall (at times with suicidal attempts) (Pontius, 1981, 1984, 1987). (2) A rare case of homicide during a fugue state with echopraxia in temporal lobe epilepsy is discussed.  相似文献

123 high school students completed the short form of the Coopersmith Self-esteem Inventory-School Form and its Lie scale, Beck's Depression Inventory, and an Alcohol Dependency Scale. Analyses of variance (2 x 4) showed boys had higher mean Lie scores than girls, and freshmen had lower mean alcohol dependency scores than sophomores, juniors, and seniors. Correlations between self-esteem scores and depression scores were significant and negative, but values were significant and positive between self-esteem and lie scores and between depression and alcohol dependency scores. Much work is required to understand better the relations among depression, self-esteem, and drug and alcohol dependency in high school students if interventions are to focus upon prevention.  相似文献

Trace mineral analysis of human hair was utilized to determine whether violent and nonviolent criminals could be differentiated on the basis of concentrations of levels of major and trace minerals. 40 violent and 40 nonviolent inmates from a prison population were selected for study. 27 mineral levels were analyzed and a discriminant function analysis correctly classified 86% of the violent and 78% of the nonviolent inmates. The results lent support to the hypothesis that significantly different levels of trace minerals could be found between the two groups.  相似文献

12 subjects from an experiment on relaxation therapy for asthma were given the Harvard Group Scale of Hypnotic Susceptibility, Form A. Full scale hypnotic susceptibility scores were positively correlated, at a borderline significance, with improvement in the methacholine challenge test, a measure of asthma severity. Performance on the amnesia item of the Harvard Group Scale was correlated with improvement in self-reported symptoms of asthma.  相似文献
