An Analysis of the Validity and Costs of Using Interviews and Questionnaires in the Study of Pay Satisfaction

This paper examines the validity and costs of using a structured questionnaire and a semi-structured interview in a study of pay satisfaction. Indices from the interview measure appeared more strongly associated with the pay satisfaction measure. However, in three out of four cases both instruments contributed independently to explaining variation in pay satisfaction. The use of different coding systems were compared in terms of validity and costs.
