Item data from two scales of the Ohio Vocational Interest Survey were used to investigate the relationship between item-favorability and sex bias. Item-response data, item sex group interaction data, and item-total score correlational data were examined. It was found that item-favorability was not a suitable criterion for the identification of existing sex bias. Of the three procedures, the item-total score correlation technique appeared to be the most sensitive to the existence of possible sex bias in the interest scales. (Author)
