Individual Beck Depression Inventory (BDI) time courses of 38 clients receiving cognitive therapy (CT) and a modified form of CT were studied in order to investigate temporal changes during CT for depression. The primary aim was to determine if alternative methods of defining and computing gains occurring early in CT would alter the conclusions drawn in the current literature. Three types of gains were studied: sudden gains (previously studied sudden, substantial, and stable improvements in depression during 1 between-session interval after Session 2), first-session gains (occurring after first sessions), and pretreatment gains (occurring after pretreatment assessments). Positive outcomes were predicted by first-session gains and by sudden gains occurring in the first half of treatment, highlighting the importance of early change in CT for depression. 相似文献

The present study was conducted to test predictions derived from the hypothesis that depression may serve the purpose of adaptively facilitating disengagement from obsolete cognitive plans. Groups of students with either low or high depression scores were contrasted using a procedure that featured an initial learning phase, within which participants learned to perform a task, followed by a relearning phase within which they needed to disengage from initial learning in order to relearn to perform an altered task. It was assumed that performance in the relearning phase would be affected by the degree to which participants could readily disengage from their initial learning. As predicted, participants in the high depression group, relative to those in the low depression group, demonstrated superior performance in the relearning phase alone. The theoretical and applied implications of this finding are discussed. 相似文献

Condom use within steady and casual sexual relationships was examined among 14-16 year old Dutch adolescents from secondary school (N?=?140). It was hypothesised that among adolescents sex and subsequently condom use with casual sex partners is less likely to be considered in advance, more context-dependent and less habitual; whereas the opposite is true for steady relationships. Therefore, preparatory behaviours (buying and carrying condoms and communicating about condom use) were expected to mediate the intention-behaviour relation in the context of steady relationships, but not in the context of casual sex. Results confirmed that condom use with steady sex partners was explained by preparatory behaviours, habits, and to some extent, behavioural willingness, and that preparatory behaviours mediated the intention-behaviour relationship. Condom use with casual sex partners was predicted by risk willingness and intentions, without any mediation by preparatory behaviours. The results indicate that it is essential to increase awareness among adolescents that unexpected sexual situations may occur and to train them to take preparatory actions. 相似文献

A meta-analysis of 50 studies was conducted to investigate whether juvenile delinquents use lower levels of moral judgment than their nondelinquent age-mates and, if so, what factors may influence or moderate the developmental delay. The results show a lower stage of moral judgment for juvenile delinquents (d=.76). Effect sizes were large for comparisons involving male offenders, late adolescents, delinquents with low intelligence, and incarcerated delinquents. The largest effect sizes were found for period of incarceration and comparisons involving juvenile delinquents with psychopathic disorder. Production instead of recognition measures, dilemma-free assessment methods, and non-blind scoring procedures yielded relatively large effect sizes, whereas effect sizes were medium for comparisons involving delinquents with average intelligence, non-incarcerated delinquents, female offenders, as well as early and middle adolescents. Psychopathic disorder and institutionalization were identified as unique moderators of the link between moral judgment and juvenile delinquency. It is concluded that developmentally delayed moral judgment is strongly associated with juvenile delinquency, even after controlling for socioeconomic status, gender, age and intelligence.This article stems from a paper presented at the meeting of the Association for Moral Education, July 2006, Fribourg, Switzerland. 相似文献

The effects of cue exposure therapy are limited, because renewal after extinction is an important source of relapse. In this study, 33 smokers were exposed to a cue predicting smoking availability and a cue predicting smoking unavailability in one context (acquisition context A). Following extinction in another context (extinction context B), a test for renewal took place in the original acquisition context A (i.e. ABA renewal). Urge to smoke was measured using a Visual Analogue Scale. Renewal of differential conditioned urge responding occurred when participants were tested in the acquisition context, while differential urge responding remained extinguished when tested in the extinction context. This experiment provides evidence that ABA renewal occurred in smokers. Clinical implications are discussed. 相似文献

This study examined a potential confound in the inverse relationship between target duration and saccadic latency reported by Adam, Ketelaars, Kingma, and Hoek in 1993. Eight participants located a briefly flashed target by moving the eyes and the cursor toward its position in a (backward) mask condition and in a no-mask condition. Analysis showed similar saccadic latencies in both conditions, thereby refuting the potentially confounding role of the backward masking procedure. It is tenatively suggested that the longer saccadic latencies noted for shorter target durations may be associated with delayed accumulation of evidence for the detection of the target. 相似文献
