Objectives. This study examined the psychometric properties of the rating scale of the Worker Role Interview (WRI). The study also asked whether the scale's items formed a valid measure of the construct, psychosocial capacity for work, and whether they were targeted to and could effectively discriminate between persons at different levels of psychosocial ability for work. Method of study. Data were collected from 21 raters on 440 participants from the United States, Sweden and Iceland. A many-faceted Rasch model was used to analyze the data. Results. Most items of the scale worked effectively to measure the underlying construct for which the WRI was designed. In addition, the items were ordered from least to more of the underlying construct as expected. The scale validly measured 90.23% of the participants, who varied by nationality, culture, age and diagnostic status. The scale's items distinguished participants into approximately three different strata and were appropriately targeted to the participants. Seventeen of the 21 raters used scale in a valid manner. Conclusions. The WRI scale and items are valid across ages, diagnoses, and culture and effectively measure a wide range of persons. [ABSTRACT FROM AUTHOR] |
