Confidence intervals for an effect size can provide the information about the magnitude of an effect and its precision as well as the binary decision about the existence of an effect. In this study, the performances of five different methods for constructing confidence intervals for ratio effect size measures of an indirect effect were compared in terms of power, coverage rates, Type I error rates, and widths of confidence intervals. The five methods include the percentile bootstrap method, the bias-corrected and accelerated (BCa) bootstrap method, the delta method, the Fieller method, and the Monte Carlo method. The results were discussed with respect to the adequacy of the distributional assumptions and the nature of ratio quantity. The confidence intervals from the five methods showed similar results for samples of more than 500, whereas, for samples of less than 500, the confidence intervals were sufficiently narrow to convey the information about the population effect sizes only when the effect sizes of regression coefficients defining the indirect effect are large. 相似文献

The Child Altruism Inventory (CAI) consisted of 24 yes-or-no items which measured the altruistic orientation of children. The sample included 1095 Grades 2 to 6 Chinese children in Hong Kong, The test-retest and internal consistency reliabilities of the CAI were in the 0.70s. The correlations of the CAI score with the intelligence and self-esteem scores were significantly positive, while the correlations of the CAI score with the psychoticism and neuroticism scores were significantly negative. Children in classes of positive and negative social environment rated high and low on the CAI respectively. The relations of the CAI score with self-report prosocial and delinquent behavioural indices were also positive and negative respectively. The psychometric properties of the CAI are regarded as quite good. 相似文献

This study examined the validity of the borderline construct which encompasses diagnostic criteria from the DSM-IV-TR Borderline Personality Disorder (BPD), ICD-10 Emotionally Unstable Personality Disorder (EUPD), and CCMD-III Impulsive Personality Disorder (IPD) in a sample of 1,419 Chinese psychiatric patients. Participants completed the Chinese Personality Disorder Inventory and the Chinese Personality Assessment Inventory-2 assessing various disordered personality features. Adequate internal consistency was found for the borderline construct (α = .83). Exploratory factor analysis revealed two components: (1) affective and cognitive disturbances, and (2) impulse dysregulation, which were replicated by confirmatory factor analysis. Item analysis indicated that the various borderline criteria displayed similar levels of diagnostic efficiency, which does not support the elimination of fear of abandonment and transient psychotic features from the EUPD and IPD criteria set. Findings of this study suggest that BPD, EUPD, and IPD may represent analogous diagnostic categories across classification systems. 相似文献

Undergraduate university students (N = 103) participated in a study of the relationship between test anxiety and the variables of trait anxiety, self-esteem, locus of control, mental ability, and gender. Results indicated bivariate associations between total test anxiety and the other measures except for mental ability. Further analyses revealed independent relationships between the "worry" component of test anxiety and the variables of trait anxiety, internality, chance, and mental ability. We also found independent associations between the "emotionality" aspect of test anxiety and the measures of trait anxiety and chance. 相似文献

Previous findings regarding the relationship between emotional valence and psychological distance were mixed. The current research examined whether emotional intensity moderates the influence of emotional valence on psychological distance. We manipulated intensity and valence by asking participants to describe a positive or negative event from either a high intensity or low intensity perspective. Studies 1 and 2 revealed that negative events were perceived to be more distant than positive events in the low‐intensity condition in two distinct cultural groups. Study 3 further proved that the obtained patterns were generalizable to different emotions. Finally, Study 4 found that a reduced alert level, but not perceived threats, mediated the interactive effects of valence and intensity on psychological distance. This research highlights the importance of considering the joint effect of different dimensions of emotion, thus advancing the understanding of complex processes of emotion. 相似文献

Compared with the rich knowledge in the West, studies of the impact of wives’ relative income on marital quality during the fast socioeconomic change period in urban China have surprisingly fallen far behind. This study attempted to examine the impact of relative income on marital happiness among urban Chinese women. Using an urban Beijing sample of 763 married women, this study found that a woman married to a husband with lower income tended to be less happy with her marriage, but this effect will be countered if there is more love in the sense of a genuine concern about the well-being of the partner and a willing to make sacrifice for him. The results were interpreted from theoretical verification and possible mechanisms linking personal commitment and marital happiness. 相似文献

Recent developments in online support and counselling suggest that the users of chat rooms, for example, or the Samaritans' e-mail 'listening' service, have already discovered the power of writing as a self-help vehicle. Developments in computer-mediated counselling and therapy are essentially text-based and client-driven. The therapeutic use of expressive and reflective writing is not widely recognised in British counselling and therapy circles. The empirical foundations for the therapeutic uses of the literary arts are, however, well established. This review aims to map the use of 'writing therapy' by drawing together cross-disciplinary research and practitioner reports which might support the place of writing as a creative therapy in its own right, whether as an adjunct to face-to-face counselling or as a self-help tool. 相似文献
