Service orientation has been suggested to be a work-related behavioral trait that contributes toward overall job performance in certain occupations. Therefore, the Batrus Hollweg Service Questionnaire (SQ), a personality inventory, was hypothesized to predict performance in a sample (N=55) of fast-food restaurant workers whose jobs were primarily composed of service-related elements. A performance evaluation form was created for use as the criterion measure. An alternative scoring system for the SQ was developed, and showed it to be significantly correlated with the criterion. The potential for use of the alternative scoring procedure is discussed.
