The coping responses of 23 hospitalized adolescent suicide attempters were compared to those of 19 hospitalized non-attempters matched on diagnosis and demographics. Relative to the comparison group, suicide attempters made fewer effortful-approach and more automatic-approach coping responses, and were judged by trained raters to have coped less effectively. Coders' ratings of greater coping effectiveness among suicide attempters were associated with a greater decline in suicidal symptoms assessed at 6-month follow-up intervals across a 2-year period. The findings are discussed in light of a model of coping that incorporates both individual differences and situational characteristics. 相似文献

Memory for the time of events may benefit from reconstructive, location-based, and distance-based processes, but these processes
are difficult to dissociate with behavioral methods. Neuropsychological research has emphasized the contribution of prefrontal
brain mechanisms to memory for time but has not clearly differentiated location- from distance-based processing. The present
experiment recorded event-related brain potentials (ERPs) while subjects completed two different temporal memory tests, designed
to emphasize either location- or distance-based processing. The subjects’ reports of locationbased versus distance-based strategies
and the reaction time pattern validated our experimental manipulation. Late (800–1,800 msec) frontal ERP effects were related
to location-based processing. The results provide support for a two-process theory of memory for time and suggest that frontal
memory mechanisms are specifically related to reconstructive, location-based processing. 相似文献

There is growing evidence that Mexican-American adolescents may be at increased risk for depressive symptoms. We sought to replicate and explain this result in a study of adolescent girls attending an obstetric-gynecologic clinic. Three hundred and four girls of diverse ethnic backgrounds completed measures of depressive symptoms, negative attributional style, and locus of control. Consistent with predictions, we found that Mexican-American adolescent girls reported more depressive symptoms than adolescent girls from other ethnic backgrounds, and that Mexican-American adolescent girls displayed more negative cognitive styles than girls from other ethnic backgrounds. Depression differences appeared to be partly explained by differences in negative cognitive style. Implications of the results for a theory of increased Mexican-American adolescent depression, and for applied work, were discussed. 相似文献

This study assesses the test-retest reliability of the revised Advanced Psychodiagnostic Interpretation (API) scoring system for the Bender Gestalt Test (BGT). The API system identifies 207 possible distortions in a BGT protocol. Test-retest reliability for 40 schizophrenic patients tested twice with a mean interval of 6.4 years (SD=3.8 years) was good, ranging from .71 to .80. Further reliability and validity studies are needed to further demonstrate the effectiveness of the system. 相似文献

Critiqued the published double-blind, placebo-controlled studies of antidepressant pharmacotherapy in child and adolescent major depressive disorder to assess their overall efficacy. The pharmacological mechanism of antidepressant action also was discussed. At best, antidepressant treatment for depressed youths is only modestly effective. In particular, the tricyclic antidepressants are not superior to placebo; however, early evidence with the selective serotonin reuptake inhibitors is more encouraging. The theoretical basis for this response pattern is discussed from a methodological perspective, from a neurodevelopmental status, and from a biological viewpoint. Study modifications are suggested which could improve some of the methodological limitations apparent in previous clinical drug trials. 相似文献

Midlife motivational abilities, that is, skills to initiate and persevere in the implementation of goals, have been related to mental and physical health, but their association with risk of mild cognitive impairment (MCI) and Alzheimer's disease (AD) has not yet been directly investigated. This relation was examined with data from the German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe). A total of 3,327 nondemented participants (50.3% of a randomly selected sample) aged 75-89 years were recruited in primary care and followed up twice (after 1.5 and 3 years). Motivation-related occupational abilities were estimated on the basis of the main occupation (assessed at follow-up II) using the Occupational Information Network (O* NET) database, which provides detailed information on worker characteristics and abilities. Cox proportional hazards models were used to evaluate the relative risk of developing MCI and AD in relation to motivation-related occupational abilities, adjusting for various covariates. Over the 3 years of follow-up, 15.2% participants developed MCI and 3.0% developed AD. In a fully adjusted model, motivation-related occupational abilities were found to be associated with a reduced risk of MCI (HR: 0.77; 95% CI: 0.64-0.92). Motivation-related occupational abilities were associated with reduced risk of AD in ApoE ε4 carriers (HR: 0.48; CI: 0.25-0.91), but not in noncarriers (HR: 0.99; CI: 0.65-1.53). These results suggest that midlife motivational abilities are associated with reduced risk of MCI in general and with reduced risk of AD in ApoE ε4 carriers. Revealing the mechanisms underlying this association may inform novel prevention strategies for decelerating cognitive decline in old age. 相似文献

A live showup (known as a street identification in the UK) allows the perpetrator to be identified shortly after a street crime. If the suspect disputes the identification, a video line‐up often ensues. Four experiments examined the reliability of live showups and their influence on a subsequent video line‐up using realistic procedures and conditions. Similar proportions of culprits and innocent suspects were identified from live showups and video line‐ups. Both culprits and innocent suspects previously identified were likely to be identified again in a subsequent line‐up, with delays from a few minutes to a month. Only a weak effect of clothing bias was observed. There was strong evidence of commitment to a previous identification but no reliable evidence of source monitoring errors. The results suggest that a live showup is not less fair than a line‐up, but the use of repeated identification procedures introduces an unfair bias against innocent suspects.

In 2 studies, we examined the use of validity screening items in adolescent survey data. In each study, adolescent respondents were asked whether they were telling the truth and paying attention in answering survey questions. In Study 1 (N = 7,801), the prevalence rates of student risk behaviors were significantly lower after inappropriate (invalid) responders were screened out of the sample. In addition, confirmatory and multigroup factor analyses demonstrated significant differences between the factor structures of school climate scales with valid versus invalid responders. In Study 2, student perceptions of school climate were correlated with teacher perceptions in 291 schools. A bootstrap resampling procedure compared the correlations obtained with valid versus invalid responding students in each school and found that valid responders had more positive views of school conditions and produced higher correlations with teacher perceptions. These findings support the value of validity screening items in improving the quality of adolescent survey data. 相似文献
