A Meta‐analytic and Conceptual Update on the Associations Between Procrastination and Multidimensional Perfectionism 下载免费PDF全文
The equivocal and debated findings from a 2007 meta‐analysis, which viewed perfectionism as a unidimensional construct, suggested that perfectionism was unrelated to procrastination. The present meta‐analysis aimed to provide a conceptual update and reanalysis of the procrastination–perfectionism association guided by both a multidimensional view of perfectionism and self‐regulation theory. The random‐effects meta‐analyses revealed a small to medium positive average effect size (r = .23; k = 43, N = 10 000; 95% confidence interval (95% CI) [0.19, 0.27]) for trait procrastination and perfectionistic concerns and a small to medium negative average effect size (r = ?.22; k = 38, N = 9544; 95% CI [?0.26, ?0.18]) for procrastination and perfectionistic strivings. The average correlations remained significant after statistically accounting for the joint variance between the two perfectionism dimensions via semi‐partial correlations. For perfectionistic concerns, but not perfectionistic strivings, the effects depended on the perfectionism measure used. All effects did not vary by the trait procrastination measure used or the respondent's sex. Our findings confirm that from a multidimensional perspective, trait procrastination is both positively and negatively associated with higher‐order perfectionism dimensions and further highlights the value of a self‐regulation perspective for understanding the cognitive, affective and behavioural dynamics that characterise these traits.

Stability or sensitivity analysis is an important topic in data analysis that has received little attention in the application of multidimensional scaling (MDS), for which the only available approaches are given in terms of a coordinate‐based analytical jackknife methodology. Although in MDS the prime interest is in assessing the stability of the points in the configuration, this methodology may be influenced by imprecisions resulting from the inherently necessary Procrustes method. This paper proposes an analytical distance‐based jackknife procedure to study stability and cross‐validation in MDS in terms of the jackknife distances, which is not influenced by the Procrustes method. For each object, the corresponding jackknife estimated points are considered as naturally clustered points, and stability and cross‐validation are analysed in terms of the MDS distances arising from the jackknife procedure, on the basis of a weighted cluster‐MDS algorithm. A jackknife‐relevant configuration is also proposed for cross‐validation in terms of coordinates, in a cluster‐MDS framework. 相似文献

The aim of this study was to investigate the relationships among secondary traumatic stress, psychological wellbeing (purpose in life, environmental mastery and self-acceptance) and life satisfaction of social workers of Namibia. A cross-sectional survey design was used with a sample population of 116 social workers. The Secondary Traumatic Stress Scale, three subscales of the Psychological Well-being Scale, the Satisfaction with Life Scale and a biographical questionnaire were administered. The results showed that secondary traumatic stress (including arousal, avoidance and intrusion) was negatively related to purpose in life, environmental mastery, self-acceptance and life satisfaction of social workers. Satisfaction with life was best predicted by environmental mastery and low arousal. Avoidance impacted life satisfaction indirectly and negatively via low environmental mastery. 相似文献

This study explored the relationship between life satisfaction, meaning in life, and religious fundamentalism among 420 participants (28.8% male, 88.4% African, 8.4% White) residing in the Gauteng province of South Africa. A cross-sectional quantitative survey design was followed. Data were collected using the Meaning in Life questionnaire and the Satisfaction with Life scale, and analysed by means of latent variable modelling. Results indicated that meaning in life acted as a mediator between religious fundamentalism and life satisfaction. This suggests that in some cases, fundamentalist religious attitudes might be adaptive in that it provides its adherents with a clear framework of meaning and definite answers to life's existential uncertainties. 相似文献

This study investigated stereotypical attitudes towards race amongst Black students (N=274) attending a historically Black South African university (females=62%; mean age of 22.15 years; SD=3.00 years). Data on group stereotyping by race were collected using a semi-structured questionnaire. The data were analysed for themes using discourse analysis. The findings indicated that Black students from a rural background stereotyped those from urban centres as lacking in African culture and being overly westernised. Conversely, rural Blacks from urban settings stereotyped those from rural areas as respectful, cultured and materially poor. Regardless of geographical origin, the Black students perceived English-speaking Whites as competent and friendly, while Afrikaans-speaking Whites were stereotyped as racist, aggressive and hardworking. The Black students perceived Indian South Africans as unethical and deceitful whilst Coloureds were noted to lack culture and to be aggressive. Findings suggest stereotypical racist language or discourse to be persistent among a student population with historical disadvantage. 相似文献

The aim of this study was to identify the cascade of effects leading from alterations in force generation around the ankle joint to increased plantar pressures under the forefoot. Gait analysis including plantar pressure measurement was performed at an individually preferred and a standardized, imposed gait velocity in diabetic subjects with polyneuropathy (n = 94), without polyneuropathy (n = 39) and healthy elderly (n = 19). The plantar flexion moment at 40% of the stance phase was negatively correlated with the displacement rate of center of pressure (r = ?.749, p < .001 at the imposed, and r = ?.693, p < .001 at the preferred gait velocity). Displacement rate of center of pressure was strongly correlated with forefoot loading (r = ?.837, p < .001 at the imposed, and r = ?.731, p < .001 at the preferred gait velocity). People with a relatively high plantar flexion moment at 40% of the stance phase, have a faster forward transfer of center of pressure and consequently higher loading of the forefoot. This indicates that interventions aimed at increasing the control of the roll-off of the foot may contribute to a better plantar pressure distribution. 相似文献

Effects of a Danish Student‐Centered Prosocial Intervention Program Among Japanese Children 下载免费PDF全文
Japan and Denmark represent two different educational cultures. Where Danish students in general report high scores on self‐esteem, Japanese children report low. A student‐centered and interaction‐based prosocial intervention program that was designed according to Danish educational culture was administered to children aged 11–12 years in Japan. Questionnaires measuring the children's quality of life (QoL) and metacognitive awareness were applied. Overall, the results showed that the student‐centered intervention improved the emotional well‐being aspect of QoL among Japanese boys. In contrast, Japanese boys’ scores on the declarative knowledge of metacognitive regulation declined. The teachers’ attitudes towards the intervention program were analyzed by use of interviews. The effect of the student‐centered intervention program is discussed with respect to the educational cultures in Japan. 相似文献
