Organizational research and practice involving ratings are rife with what the authors term ill-structured measurement designs (ISMDs)--designs in which raters and ratees are neither fully crossed nor nested. This article explores the implications of ISMDs for estimating interrater reliability. The authors first provide a mock example that illustrates potential problems that ISMDs create for common reliability estimators (e.g., Pearson correlations, intraclass correlations). Next, the authors propose an alternative reliability estimator--G(q,k)--that resolves problems with traditional estimators and is equally appropriate for crossed, nested, and ill-structured designs. By using Monte Carlo simulation, the authors evaluate the accuracy of traditional reliability estimators compared with that of G(q,k) for ratings arising from ISMDs. Regardless of condition, G(q,k) yielded estimates as precise or more precise than those of traditional estimators. The advantage of G(q,k) over the traditional estimators became more pronounced with increases in the (a) overlap between the sets of raters that rated each ratee and (b) ratio of rater main effect variance to true score variance. Discussion focuses on implications of this work for organizational research and practice. 相似文献

Studies suggest that the process of acculturation for immigrant youth, particularly for second-generation youth, is significantly associated with delinquency and violence. This study explored the acculturation-violence link with respect to acculturative dissonance and ethnic identity. The results revealed in a sample of 329 Chinese, Cambodian, Mien/Laotian, and Vietnamese youth that acculturative dissonance was significantly predictive of serious violence, with full mediation through peer delinquency. Ethnic identity was not significantly associated with peer delinquency or serious violence. Although acculturative dissonance and ethnic identity accounted for a small percentage of variance in violence compared with peer delinquency, it cannot be discounted as trivial. Structural equation analyses provided support for both measurement and structural invariance across the four ethnic groups, lending support for cross-cultural comparisons. The results also lend support for the inclusion of cultural factors in youth violence prevention and intervention efforts. 相似文献

通过对176名大学新生3个月的纵向研究,采用探索性因素分析、信度分析和回归分析等方法对目标定向与适应的关系以及社会自我效能感在其中的中介作用进行了深入研究。结果表明,(1)学习目标定向能够有效地预测个体的学业适应、社会适应和心理适应;而成绩目标定向对三类适应都无显著性影响;(2)社会自我效能感在学习目标定向与社会适应、心理适应之间具有完全中介效应,而对学习目标定向与学业适应之间没有中介作用;(3)社会自我效能感对学业适应无显著性影响。 相似文献

肾上腺素是临床上心肺复苏的一线药物,但在最近二十几年以来,其剂量应用方案几经变迁,从20世纪80年代的小剂量,到90年代大剂量方案的兴起,又经历了个体化方案阶段,近几年又重新回归到小剂量给药方案。从唯物辩证法的基本思想出发,阐述心肺复苏时肾上腺素剂量变迁的哲学基础,并运用辩证唯物主义原理来探讨肾上腺素剂量研究的发展方向,这将有助于心肺复苏研究的理论与实践。 相似文献

Subtyping adolescents with bulimia nervosa 总被引:1,自引:0,他引:1
Cluster analyses of eating disorder patients have yielded a "dietary-depressive" subtype, typified by greater negative affect, and a "dietary" subtype, typified by dietary restraint. This study aimed to replicate these findings in an adolescent sample with bulimia nervosa (BN) from a randomized controlled trial and to examine the validity and reliability of this methodology. In the sample of BN adolescents (N=80), cluster analysis revealed a "dietary-depressive" subtype (37.5%) and a "dietary" subtype (62.5%) using the Beck Depression Inventory, Rosenberg Self-Esteem Scale and Eating Disorder Examination Restraint subscale. The "dietary-depressive" subtype compared to the "dietary" subtype was significantly more likely to: (1) report co-occurring disorders, (2) greater eating and weight concerns, and (3) less vomiting abstinence at post-treatment (all p's<.05). The cluster analysis based on "dietary" and "dietary-depressive" subtypes appeared to have concurrent validity, yielding more distinct groups than subtyping by vomiting frequency. In order to assess the reliability of the subtyping scheme, a larger sample of adolescents with mixed eating and weight disorders in an outpatient eating disorder clinic (N=149) was subtyped, yielding similar subtypes. These results support the validity and reliability of the subtyping strategy in two adolescent samples. 相似文献

Recent research suggests that personality traits are associated with delinquency. T-tests were run to identify which traits and facets of the Five-Factor Model of Personality contributed to differentiate persistent juvenile delinquents (n = 48) from normative peers (n = 48). Results showed that two traits, namely Agreeableness and Neuroticism, and 12 facets differed significantly between the groups. Observed effect sizes varied from medium to large. 相似文献

This study examined the relationship between heart rate variability (HRV), as an index of individual differences in emotion
regulation, and perception of other-blame, as a mechanism of anger induction. The physiological responses were recorded while
subjects read a story from a computer screen. The story narrated a negative event in self-referred way -dismissal from a job
as the result of a colleague’s action- under conditions of intentionality versus non-intentionality. Cognitive and emotional
variables were assessed by questionnaire immediately after the physiological test. The resulting structural model supports
the conclusion that HRV exerts its regulatory influence directly on perception of other-blame rather than on emotion. In situations
of intentionality, individuals with higher HRV make less extreme evaluation of the offender’s blame, versus those with lower
HRV, thus leading to a reduction in anger reaction. These results suggest that HRV is a direct index of cognitive rather than
emotional regulation. 相似文献

Loneliness can be regarded as an epidemic of modern society that is becoming increasingly problematic for millions of people.
Adolescents are particularly susceptible to the development of this kind of emotional distress. Although many causes of loneliness
can be identified, some researchers are of the opinion that it can also be attributed to unpleasant childhood experiences
that result in unfulfilled needs relating to intimacy. In this research study, the relationship between loneliness and adolescents’
attitudes towards their fathers was investigated. In order to achieve this goal, information was gathered from 1068 South
African respondents. Biographical questionnaires were administered and a Loneliness Scale was applied. In addition, adolescents’
attitudes towards their fathers were measured by means of a Fathers Questionnaire. Steps were taken to determine which of
the independent variables, namely gender, age, race, language and socio-economic status, contributed significantly to the
prediction of loneliness. In order to process the acquired information, a stepwise multiple regression analysis was conducted.
The most important finding of this study is that adolescents’ attitudes towards their fathers comprise the most prominent
predictor of loneliness during adolescence. The results also indicated that all of the independent variables had a statistically
significant influence on loneliness. 相似文献
