Establishing the Measurement Equivalence of Online Selection Assessments Delivered on Mobile versus Nonmobile Devices

Recent usage data suggest job applicants are completing online selection assessments using mobile devices (e.g., smartphones) in greater numbers. To determine the appropriateness of this new technology, this study examined the measurement equivalence of selection assessments delivered on mobile and nonmobile devices (e.g., personal computers). Measurement invariance tests conducted with multigroup confirmatory factor analysis suggest mobile versions of a cognitive ability-type assessment, two biodata assessments, a multimedia work simulation, and a text-based situational judgment test appear to be equivalent to nonmobile versions. However, mobile device user latent means were half a standard deviation lower than their nonmobile counterparts for the situational judgment test. Implications for mobile device usage within selection and assessment are discussed.
