An Evaluation of the Brief Symptom Inventory-18 Using Item Response Theory: Which Items Are Most Strongly Related to Psychological Distress?
Meijer, Rob R.; de Vries, Rivka M.; van Bruggen, Vincent
Psychological Assessment, v23 n1 p193-202 Mar 2011
The psychometric structure of the Brief Symptom Inventory-18 (BSI-18; Derogatis, 2001) was investigated using Mokken scaling and parametric item response theory. Data of 487 outpatients, 266 students, and 207 prisoners were analyzed. Results of the Mokken analysis indicated that the BSI-18 formed a strong Mokken scale for outpatients and prisoners, indicating strong unidimensionality. For students, only the depression and anxiety items formed a medium Mokken scale. Parametric item response theory analyses showed that the best discriminating items came from the depression and anxiety subscales. (Contains 3 figures and 6 tables.)
