Evaluation of Model Fit in Cognitive Diagnosis Models

Cognitive diagnosis models (CDMs) estimate student ability profiles using latent attributes. Model fit to the data needs to be ascertained in order to determine whether inferences from CDMs are valid. This study investigated the usefulness of some popular model fit statistics to detect CDM fit including relative fit indices (AIC, BIC, and CAIC), and absolute fit indices (RMSEA2, ABS(fcor) and MAX(χ²_jj′)). These fit indices were assessed under different CDM settings with respect to Q-matrix misspecification and CDM misspecification. Results showed that relative fit indices selected the correct DINA model most of the times and selected the correct G-DINA model well across most conditions. Absolute fit indices rejected the true DINA model if the Q-matrix was misspecified in any way. Absolute fit indices rejected the true G-DINA model whenever the Q-matrix was under-specified. RMSEA2 could be artificially low when the Q-matrix was over-specified.     

Measuring Customer Service Orientation: An Examination of the Validity of the Customer Service Profile

The construct of customer service is taking on an ever increasing level of importance in today's global economy. Organizations need a way to identify those individuals who have the demeanor to effectively serve the public. The present study discusses the development and validation of a personality-based instrument which organizations can use to select high-quality service providers. Multiple converging sources of validity are discussed. Specifically, the authors collected validity evidence using customer related (vs. supervisor) ratings, an area relatively neglected in the service literature. Evidence suggests that customer ratings are viable and an important criterion for use in the validation of customer service instruments. Implications of these findings are discussed in terms of both workplace intervention and future research.     

中国人人格形容词评定量表(QZPAS)的信度、效度与常模

本研究的目的是建立中国人人格形容词评定量表(QZPAS)的信度、效度和常模。4000多名被试对由123个形容词组成的QZPAS的评定结果支持了中国人人格的“大七”模型,各因素有着良好的内部一致性和重测信度。自-他评定的相关以及自我总体评定与量表分数间的相关表明QZPAS有良好的效标效度。本研究所提供的常模也为该量表的应用提供了基础。     

Cross‐cultural validation of the counselor burnout inventory in hong kong

This study investigated the cross‐cultural validation of the Chinese translation of the Counselor Burnout Inventory (CBI) with a sample of school counselors in Hong Kong. Specifically, this study examined the CBI's factor structure using confirmatory factor analysis and calculated the effect size, to compare burnout scores among the counselors of 4 countries (Hong Kong, Japan, South Korea, and the United States). Results indicated that a 5‐factor model was the most appropriate to accommodate the data. In addition, the results showed that the levels of Hong Kong counselors’ burnout were similar to those of U.S. counselors, but differed from counselors in Japan and South Korea.
