The Impact and Detection of Uniform Differential Item Functioning for Continuous Item Response Models
Educational and Psychological Measurement, Volume 83, Issue 5, Page 929-952, October 2023.
Psychometricians have devoted much research and attention to categorical item responses, leading to the development and widespread use of item response theory for the estimation of model parameters and identification of items that do not perform in the same way for examinees from different population subgroups (e.g., differential item functioning [DIF]). With the increasing use of computer-based measurement, use of items with a continuous response modality is becoming more common. Models for use with these items have been developed and refined in recent years, but less attention has been devoted to investigating DIF for these continuous response models (CRMs). Therefore, the purpose of this simulation study was to compare the performance of three potential methods for assessing DIF for CRMs, including regression, the MIMIC model, and factor invariance testing. Study results revealed that the MIMIC model provided a combination of Type I error control and relatively high power for detecting DIF. Implications of these findings are discussed.

Development and Validation of the Adaptive Schema Questionnaire
Indian Journal of Psychological Medicine, Volume 45, Issue 5, Page 476-485, September 2023.
Background:Schemas help with the organization and interpretation of information. Adaptive schemas indicate positive predisposing thinking patterns in an individual. This study aimed to develop a psychometrically robust tool to assess adaptive schema in a nonclinical sample.Method:This research comprises two independent studies. Study I was multiphased. In Phase I (n = 70), 36 open-ended items were generated following the Young schema therapy model and qualitatively analyzed. This facilitated the generation of 144 items in Phase II (n = 152) which were evaluated for content validity and subjected to rigorous item analysis. Exploratory factor analysis was performed in Phase III (n = 751). Confirmatory factor analysis was conducted in Study II (n = 244).Results:Exploratory factor analysis resulted in a six-factor solution comprising 25 items. These factors correspond to the six adaptive themes, namely, adequate, secured, self-reliant/autonomous, resistant, successful, and self-assured. The newly developed Adaptive Schema Questionnaire demonstrated adequate reliability (α = 0.86). Significant correlations between the obtained factors and Early Maladaptive Schemas, depression, big five personality factors, and positive and negative effects established the concurrent validity. Confirmatory factor analysis indicated acceptable goodness of fit for the obtained model.Conclusion:The developed Adaptive Schema Questionnaire is a reliable and valid instrument with promising utility in psychotherapy and research context.
