The purpose of the present study was to investigate the relationships among suicidality, substance use, self-esteem, family structure, and eight personality characteristics (harm avoidance, impulsivity, aggression, social recognition, cognitive structure, succorance, abasement, and achievement) with 337 talented, at-risk, adolescent girls. Results indicated that girls with histories of suicidal ideations and/or attempts had significantly higher levels of substance use, impulsivity, aggression, and social recognition, and significantly lower levels of self-esteem and harm avoidance than girls without such histories. Girls without suicide histories were also more likely to come from single mother families. Consideration of these factors, by both researchers and clinicians, in assessing suicide risk is encouraged. 相似文献

Participants viewed episodes in the form of a series of photographs portraying ordinary routines (e.g., eating at a restaurant) and later received a recognition test. In Experiment 1, it was shown that objects (e.g., a vase of flowers, a pewter lantern) that appeared in a single episode during the study phase migrated between memories of episodes described by the same abstract schema (e.g., from Restaurant Episode A at study to Restaurant Episode B at test), and not between episodes anchored by different schemas. In Experiment 2, it was demonstrated that backward causal inferences from one study episode influenced memories of other episodes described by the same schema, and that high-schema-relevant items viewed in one episode were sometimes remembered as having occurred in another episode of the same schematic type. 相似文献

Psychosocial and socioeconomic variables are often confounded. The authors combined quantitative with grounded theory analysis to investigate influences of acculturation, socioeconomic status (SES), and cultural health beliefs on Mexican-descent women's preventive health behaviors. In 5 focus group interviews sampling across levels of acculturation and SES, women expressing more traditional Mexican health beliefs about breast cancer screening were of lower SES and were less U.S. acculturated. However, SES and acculturation were uncorrelated with screening behaviors. Qualitative analysis generated hypotheses about joint influences of SES and traditional health beliefs; for example, low-SES women may learn frugal habits as part of their cultural traditions that influence their health care decision making, magnifying SES-imposed structural restrictions on health care access. 相似文献

A previous study (Gilat et al., J. Exp. Psychol. Appl. 3 (1997) 83) has shown that the incentive to reach consensus can raise the tendency to rely on base rates in signal detection decisions and can reduce the probability that less likely events will be accurately classified. This phenomenon was named the “consensus effect”. The current study assesses the conditions under which this effect develops and in particular the effects of information about the game and of the incentive structure on the learning process. The results of three experiments show that the learning process slows when participants have information about the actual state of nature. This finding is captured by a reinforcement learning model with the assumption that information narrows the distribution of the initial propensities for choosing among cutoffs. The results are further evidence for the utility of the combination of learning models and analyses of cognitive processes for the prediction of decision making in situations involving multiple players. 相似文献

This article examines how Black churches serve as therapeutic groups and thus provide a source of psychological support to African American communities. Group theory is used as a conceptual framework to discuss the findings from 7 focus groups conducted in Black churches in the New York metropolitan area. Implications for counselors working with clients involved in the Black religious tradition are discussed. 相似文献

Using Olsen and Cromwell's (1975) three facetsof interpersonal power (power in resources, process, andoutcomes), we examined the balance of power in lateadolescent romantic relationships and the associations between interpersonal power, adolescents'self-esteem, and depression. Participants were 61adolescent couples who were primarily European-American(90% of girls and 93% of boys), with the remainder being comprised of approximately 2-3% each of NativeAmerican, Asian, African American, and Hispanicindividuals. We assessed power in terms of access toemotional resources, control during video-tapedinteraction, and control over decision-making. Overall,couples were more likely to be described by themselvesand by independent observers as egalitarian, with themajority of couples equally contributing emotional resources, sharing power in interaction, andsharing decision-making responsibility. However,romantic relationships characterized by inequality inthe contribution of emotional resources and indecisionmaking were associated with greater psychologicalsymptomatology, especially for females. 相似文献

Many media reports contend that American youth are dangerous, self-possessed, and care too little about their personal education or the broader society. Not only are youth criticized, but their teachers and schools are subjected to exaggerated criticism. We argue that the average, undifferentiated view of youth as presented by the media is inaccurate and pejorative. Researchers have added to the chorus of unfounded negative assertions about youth and their schools. As an example, Laurence Steinberg, in Beyond the Classroom, argued that American students' levels of academic achievement were woefully inadequate. He argued that students did not do enough homework, that they cheated, and that pervasive, negative peer pressure undermined academic achievement. The purpose of our study was to examine students' attitudes and perceptions in three major areas – cheating, homework, and peer pressure. Using data from over 700 students drawn from one public high school and one junior high school, our results indicated that students' beliefs and norms concerning cheating, homework, and peer pressure varied widely in terms of gender, GPA, and school context. Our data failed to replicate the findings from Beyond in that (a) our average findings were more positive than those reported in that study, and (b) we showed that the reporting of average was highly misleading. Our findings provided evidence that one cannot describe American students in a general, sweeping way. Average statements about youth, especially adolescent youth, are apt to be very misleading. 相似文献

One hundred fifty randomly selected articles published in Journal of Personality from 1970 to 1995 were evaluated with regard to subject population, sampling, research design, dependent measures, statistical methods, methodological difficulty, sample size, manipulation of independent variables (for experimental studies), use of manipulation checks, and gender representation of authors and participants. Our findings support Endler and Speer's (this issue) conclusion that the typical study in personality research continues to use a cross-sectional design, questionnaire measures, and undergraduate participants. Echoing West et al.'s (1992) findings for Journal of Personality and Social Psychology, we found that whereas subject recruitment and design implementation appear to be less difficult than they were two decades ago, statistical analyses have become somewhat more complex. 相似文献
