This study investigated the incidence of serious suicidal thoughts (ST's) among 207 high school seniors and 901 college students, and the relationship between ST's and family stress, drinking and drug-abuse problems, and delinquency in these groups. Over 10% of the high school and over 6% of the college students reported ST's. Those considering suicide attempts in both groups were more likely than their classmates to view their parents as having many conflicts with each other, to think of their relationship with their father as poor, to see at least one of their parents as either angry or depressed much of the time, and to perceive themselves as having a drinking or drug-abuse problem. These findings support the call for comprehensive counseling programs at both the high school and college levels.  相似文献

Rats were given backward pairings of a tone (CS) and shock (US) and were then tested for response to the CS in a lick suppression test. Animals given a cuing or reminder treatment prior to the test exhibited enhanced suppression in the presence of the tone relative to a variety of control conditions. The cue-induced suppression enhancement did not appear to result from sensitization or short-term motivational changes nor did it seem to depend on second-order conditioning of the test context. The effect appeared more robust as the number of backward conditioning trials preceding the cue increased. The results were discussed in terms of current explanations of backward conditioning effects.  相似文献

The present study examined the direction of the relation between sex role self-concept and depression. A total of 23 males and 32 females were given the Personal Attributes Questionnaire and the Beck Depression Inventory at two times separated by a 3-month interval. Results of a cross-lagged panel correlational analysis found no evidence for sex role orientation as a cause of depression. Instead, the data suggested that emotional well being precedes self-perceived instrumentality, but the influence of third variables could not be overlooked. The implications of these data are discussed with particular reference to the need for more complex theoretical formulations of the relation between self-perceived instrumentality and adjustment.  相似文献

A conditional approach to dispositions is developed in which dispositional constructs are viewed as clusters of if-then propositions. These propositions summarize contingencies between categories of conditions and categories of behavior rather than generalized response tendencies. A fundamental unit for investigating dispositions is therefore the conditional frequency of acts that are central to a given behavior category in circumscribed situations, not the overall frequency of behaviors. In an empirical application of the model, we examine how people's dispositional judgments are linked to extensive observations of targets' behavior in a range of natural social situations. We identify categories of these social situations in which targets' behavior may be best predicted from observers' dispositional judgements, focusing on the domains of aggression and withdrawal. One such category consists of subjectively demanding or stressful situations that tax people's performance competencies. As expected, children judged to be aggressive or withdrawn were variable across situations in dispositionally relevant behaviors, but they diverged into relatively predictable aggressive and withdrawn actions in situations that required the social, self-regulatory, and cognitive competencies they lacked. Implications of the conditional approach for personality assessment and person perception research are considered.  相似文献

The present study was conducted to examine the hypothesis that compliant chronically ill patients, typically described as adjusted, reinforce more positive social environments using behavioral controls than noncompliant patients, typically described as maladjusted. Specifically, it is hypothesized that diet-compliant chronic hemodialysis patients emit significnatly more active involvement-in-treatment behaviors and more social behaviors than diet-noncompliant chronic hemodialysis patients. Subjects, who ranged in age from 30 to 77 years, were outpatients at a kidney center. Behavioral observations were conducted to assess the occurrence or frequency of (1) four involvement-in-treatment behaviors that are routinely taught to all patients and (2) two social behaviors, which were patient verbalizations and smiles. The results showed that compliant patients emitted significantly more involvement-in-treatment behaviors and smiles than noncompliant patients. Results support the proposed control framework that compliant, in contrast to non-compliant, chronically ill patients have recourse through positive behavioral controls when adjusting to the stresses of illness. It was proposed that through these controls, compliant patients reinforce positive environments rather than simply respond to life circumstances as given.  相似文献
