摘要：Mokken scaling techniques are useful tool for researchers aiming to construct unidimensional scales and sub-scales that comprise multiple binary or polythomous items. This technique offers stochastic cumulative scaling models and these models are ideally suited when the participants’ level of the assessed traits are investigated with item parameters. Mokken models belong the class of Nonparametric Item Response Theory and extend the deterministic Guttman scaling technique. In the current study, the suitability of The Occupational Motivation Scale (OMI) that had been developed based on Guttman scaling method was investigated. The scale was applied to 155 undergraduate students and Mokken scale analysis was performed in R program with “mokken” package. The Mokken scale analysis yielded that the OMI was composed of two sub-scales that were convenient with Monotone Homogenity Model allows for individuals’ ordering based on total scores. The sub-scales measure the intrinsic and extrinsic motivation and the number of items decreased 60 to 41, however the reliability of the scale was found so high, 0,9As a result, it can be concluded that OMI was enabled to be scaled in Mokken scale and with fewer items, the scale can measure the same latent trait with high reliability.
