This paper presents an IRT analysis of the Beck Depression Inventory which was carried out to assess the assumption of an underlying latent trait common to non-clinical and patient samples. A one parameter rating scale model was fitted to data drawn from a patient and non-patient sample. Findings suggest that while the BDI fits the model reasonably well for the two samples separately there is sufficient differential item functioning to raise serious duobts of the viability of using it analogously with patient and non-patient groups.

The purpose of this study was to investigate a new way of evaluating interrater reliability that can allow one to determine if two raters differ with respect to their rating on a polytomous rating scale or constructed response item. Specifically, differential item functioning (DIF) analyses were used to assess interrater reliability and compared with traditional interrater reliability measures. Three different procedures that can be used as measures of interrater reliability were compared: (1) intraclass correlation coefficient (ICC), (2) Cohen’s kappa statistic, and (3) DIF statistic obtained from Poly-SIBTEST. The results of this investigation indicated that DIF procedures appear to be a promising alternative to assess the interrater reliability of constructed response items, or other polytomous types of items, such as rating scales. Furthermore, using DIF to assess interrater reliability does not require a fully crossed design and allows one to determine if a rater is either more severe, or more lenient, in their scoring of each individual polytomous item on a test or rating scale.

This study explored academic discipline as a source of differential item functioning(DIF) in students’ rating of teaching quality and effectiveness at higher education institutions. Data utilized in this study was collected by Imam Abudalruman Bin Faisal University - KSA. The total number of surveys analyzed for the purpose of this study is 36459 from three colleges: Education, Health, and Engineering. Using Extended Rasch model (Rating Scale Model), the results show that the instrument contains four DIF items. The content of these four items confirm the possibility of considering discipline as a source of DIF items in students evaluation of teaching in higher education. Moreover, the results of the current study show that removing DIF items from the instrument increases construct validity.

Abstract Background The Patient Health Questionnaire (PHQ-9) is a widely used self-report questionnaire to screen depression. Its psychometric property has been tested in many populations including health care workers. We used Rasch measurement theory to examine the psychometric properties of PHQ-9 regarding item difficulty, item fit and the differences between subgroups of respondents classified by sex, age, education and alcohol user status, based on the same overall location of participants.Methods In total, 3,204 health care workers of Maharaj Nakorn Chiang Mai Hospital participated and were administered the PHQ-9. Rating scale Rasch measurement modeling was used to examine the psychometric properties of the PHQ-9.Results The data fitted well to the Rasch model and no violations of the assumption of unidimensionality were observed. All 9 items could form a unidimensional construct of overall depressive severity. Suicidal ideation was the least endorsed while sleep problem was the most. No disordered category and threshold of the rating response were observed. No locally dependent items were observed. No items were found to show differential item functioning across age, sex, education and alcohol consumption. The item-person Wright map showed that the PHQ-9 did not target well with the sample, and a wide gap suggesting few or no items exist to differentiate participants at a certain ability level among the PHQ-9 items.Conclusion The PHQ-9 can be used as a screening questionnaire for major depressive disorder as its psychometric property was verified based on Rasch measurement model. The findings are generally consistent with related studies in other populations. However, the PHQ-9 may be unsuitable for assessing depressive symptoms among health care workers who have low levels of depression.

Menopause Rating Scale

Introduction.Quality of life could be quantified with the Menopause Rating Scale (MRS), which evaluates the severity of somatic, psychological, and urogenital symptoms in menopause. However, differential item functioning (DIF) analysis has not been applied previously.Objective. To establish the DIF of the psychological domain of the MRS in Colombian women.Methods. 4,009 women aged between 40 and 59 years, who participated in the CAVIMEC (Calidad de Vida en la Menopausia y Etnias Colombianas) project, were included. Average age was49.0±5.9years. Women were classified in mestizo, Afro-Colombian, and indigenous. The results were presented as averages and standard deviation (X±SD). Apvalue <0.001 was considered statistically significant.Results. In mestizo women, the highestX±SDwere obtained in physical and mental exhaustion (PME) (0.86±0.93) and the lowest ones in anxiety (0.44±0.79). In Afro-Colombian women, an average score of0.99±1.07for PME and0.63±0.88for anxiety was gotten. Indigenous women obtained an increased average score for PME (1.33±0.93). The lowest score was evidenced in depressive mood (0.50±0.81), which is different from other Colombian women (p<0.001).Conclusions. The psychological items of the MRS show differential functioning according to the ethnic group, which may induce systematic error in the measurement of the construct.
