Although evidence is accumulating on the immediate or short-term efficacy of cognitive-behavioural strategies in the treatment of school refusal, no studies have been reported on the long-term efficacy of this treatment approach. An earlier randomized clinical trial conducted by the authors demonstrated the efficacy of a manual-based cognitive-behavioural treatment program for school refusal relative to waiting list controls. We now report findings of a 3- to 5-year follow-up investigation of the treatment group. In general, results support the long-term efficacy of the treatment program, with children showing maintenance of improvements in school attendance and school adjustment. Methodological limitations of the follow-up investigation are emphasized.  相似文献

An increasingly popular clinical impression is that physical victimization plays an important role in the etiology of bulimia. There are few data based studies, however, which have tested this belief. Therefore, data were collected to determine if those who have been victimized are more apt to be bulimic than those who have not been victimized. The four forms of victimization explored were rape, sexual molestation, child abuse and partner abuse. Only child abuse was statistically significantly related to bulimia in the bivariate analyses, although all relationships were in the predicted direction. In the multivariate analysis, severity of bulimic‐like symptoms was regressed on the four forms of victimization and on nine demographic characteristics. Child abuse was the only form of victimization related to the severity of symptoms, when controlling for the effects of the other variables. Contrary to clinical impressions, the effect of sexual molestation on severity of bulimic symptoms was negative, but not statistically significant. Among the demographic characteristics, only the number of sisters had a significant effect. The combined effect of being both bulimic as well as a victim did not increase the likelihood of seeking therapy for an eating disorder. The need for empirical evidence to verify clinical impressions is stressed.  相似文献

Stable tendency to perseverative thoughts such as trait rumination and worry can influence somatic health. The purpose of the study was to investigate the relationship between perseverative thoughts and somatic complaints, and the possible mediating effects of perceived stress, negative and positive affectivity in adolescence. Having an acute or a chronic condition was also assessed to be controlled for and to reveal their effects on symptom reporting. Three hundred and six adolescents from 7th to 12th grade with mean age of 16.33 (SD = 1.29) participated in the study. Mediation analysis suggested that impact of trait-like perseverative thoughts on complaints were mediated by perceived stress and negative affectivity. Having an acute condition had also an effect on symptom reporting through increased negative affectivity. Our results highlight that ruminations or worry as stable intrapersonal characteristics are relevant processes in health and can be potential targets in prevention programmes in adolescence.  相似文献

Abstract

A model of adolescent health risk behavior that is both cognitive and social-psychological in orientation is described, and an aspect of the model is tested empirically. The model suggests that health risk behaviors (e.g., smoking or drunk driving), especially among adolescents, are not always intended or premeditated, but instead are often reactions to risk-conducive circumstances. Because they are not entirely premeditated, such behaviors are not accurately predicted by “traditional” behavioral intention measures, but are predicted by a central construct in the model labeled behavioral willingness. Results of two studies indicate that both intention (expectation) and willingness measures predict future risk behaviors, and do so independent of one another. Additional analyses provide further evidence of discriminant validity between the two constructs by indicating that they relate differently to perceptions of personal vulnerability to the health risks associated with these behaviors.  相似文献

ABSTRACT

Unlike previous studies, the present experiment was designed to directly compare negative (NP) and positive priming (PP) in 37 young (mean age: 21.5 years) and 37 older adults (mean age: 69.4 years) by means of two independent identity- and location-based priming tasks. While identity PP was shown to be reduced in older adults, no age-related differences were found for location PP. This pattern of results supports the notion that mechanisms involved in identity- and location-based PP are largely independent of each other. Both age groups exhibited reliable identity and location NP although location NP was decreased in older adults. Extremely low temporal test–retest coefficients indicated that mechanisms underlying identity and location NP represent situational states rather than stable traits. This lack of temporal stability may also account for highly ambiguous results obtained in previous studies.  相似文献

Studies of memory bias for threat-relevant information in individuals with social anxiety have produced mixed results. These discrepancies may be because investigators have studied different memory processes or have used different memory tasks. We employed a video clarity judgement task to investigate implicit (capacity-free, automatic, unconscious) memory and a recognition task to investigate explicit (effortful, strategic, conscious) memory for threat in socially anxious individuals and nonanxious controls. Implicit memory for "old" (i.e., seen before) videos was defined as rating "old" videos as more clear than "new" (i.e., never seen before) videos. We created brief video clips that involved an actor or actress approaching the camera and commenting on some aspect of the viewer's actions, physical appearance, or belongings. Twenty-four videos were positive (e.g., "I really like your shoes"), and 24 were negative (e.g., "That is a horrible haircut"). Results revealed that the video clarity test was an effective measure of implicit memory. Furthermore, socially anxious individuals showed a larger implicit memory index for negative videos than did nonanxious and dysphoric controls. No group differences emerged for implicit memory for positive videos. Similarly, groups did not differ in recognition of, or false alarms for, positive and negative videos. These results demonstrate the role of implicit memory in social anxiety implying that information about threat may be automatically primed in these individuals.  相似文献

Although job analysis is a widely used organizational data collection technique, little research has investigated the extent to which job analysis information is affected by self-presentation processes. This study represents the first direct test of the propositions offered by F. P. Morgeson and M. A. Campion (1997) concerning self-presentation in job analysis measurement. Using an experimental design, the authors examined job incumbent response differences across ability, task, and competency statements. Results indicated that ability statements were more subject to inflation than were task statements across all rating scales. Greater endorsement of nonessential ability statements was responsible for the differences. This produced higher endorsement of ability items but lower mean ratings. Finally, frequency and importance ratings of global competency statements were generally higher than decomposed ability and task scales, but required-at-entry judgments demonstrated the opposite relationship.  相似文献

Immediate memory span and maximal articulation rate were assessed for word sets differing in frequency, word-neighborhood size, and average word-neighborhood frequency. Memory span was greater for high- than low-frequency words, greater for words from large than small phonological neighborhoods, and greater for words from high- than low-frequency phonological neighborhoods. Maximal articulation rate was also facilitated by word frequency, phonological-neighborhood size, and neighborhood frequency. In a final study all 3 lexical variables were found to influence the recall outcome for individual words. These effects of phonological-word neighborhood on memory performance suggest that phonological information in long-term memory plays an active role in recall in short-term-memory tasks, and they present a challenge to current theories of short-term memory.  相似文献

R. F. Wang and E. S. Spelke's (2000) finding that disorientation disrupts knowledge is consistent with egocentric but not allocentric coding of object location. The present experiments tested the hypothesis that egocentric coding may dominate early on but that once an allocentric representation is established, then target location is retrieved from it. This hypothesis predicts that disorientation will disrupt configuration knowledge in a novel environment, such as that used by Wang and Spelke, but not in an overlearned environment. Experiments 1 and 2 tested whether disorientation disrupted configuration knowledge of an overlearned environment, and Experiments 3-7 tested whether disorientation disrupted configuration knowledge of a novel, room-sized environment. In none of the experiments did disorientation disrupt configuration knowledge. Hence, in addition to showing allocentric coding of overlearned interlandmark relations, the present findings are consistent with the immediate availability of allocentric location codes in a novel, room-sized environment.  相似文献

To examine affect and cognition in differentiating anxiety and depression, 83 older participants with generalized anxiety disorder completed the Cognitive Checklist (CCL) and the Positive and Negative Affect Schedule (PANAS). A 3-factor solution was found for the PANAS: positive affect (PA), anxiety and anger (Negative Affect 1 [NA-1]), and guilt and shame (Negative Affect 2 [NA-2]). A 2-factor structure was noted for the CCL. Correlations with anxiety and depression measures suggested that the CCL Depression (CCL-D) subscale showed stronger correlations with depression, whereas the CCL Anxiety subscale did not uniquely correlate with anxiety. The NA-1 subscale correlated positively with measures of depression and anxiety, whereas the PA subscale showed negative correlations. Hierarchical regression suggested that the CCL-D subscale was a significant predictor of self-reported depression.  相似文献
