Lead consultant at Test Partnership, Ben Schwencke, explains what is a local validity study.
Local validity studies refer to the process of assessing the validity of a psychological assessment in a specific population or context. These studies are used to determine whether an assessment is appropriate for use in a specific setting, such as a particular company or organisation. Local validity studies are particularly important in employee selection, where the assessment needs to be tailored to the specific requirements of the job and the organisation. Typically, when running a local validity study, criterion-related validity is the primary mechanism by which validity is assessed, with organisations showing less interest in construct, content, or face validity.
Local validity studies involve collecting data from the specific population or context in which the assessment will be used. For example, an occupational psychologist could measure the job performance of incumbent employees, and then measure their personality using a questionnaire. This data is then used to compare the results of the assessment with the job performance of the employees in that population or context, establishing whether or not the assessment is able to predict job performance. This process allows for the identification of any potential bias or lack of relevance in the assessment, and to make any necessary adjustments to the assessment to improve its local validity.
