This paper contends that the recent development of organizational socialization (OS) scales has been so closely intertwined with OS content research that OS scale dimensions have been identified as specific OS contents, without fully taking into consideration the underlying OS processes. As a result, existing OS scales are unsatisfactory because they do not provide a comprehensive measure of the OS construct and/or reveal conceptual mismatches. First, this paper challenges existing OS scales by integrating a content-based and a process-based analysis of OS scales. Second, we define six dimensions of the OS construct, as a ground for future OS scale development.
