A Comparison of Five Criteria for Identifying Fakable Items on an Attitude Inventory
The fakability of responses to the Attitude Toward Disabled Persons Inventory (ATDP) was investigated through applying two criteria requiring subjects to identify the favorable responses and three using “honest” test - “faked response” retest techniques. Considerable differences were noted among the items indentified as non-fakable by use of the different criteria. Regardless of the criterion applied, less than 25% of the items were identified as not fakable. Serious objections were raised to any method of identifying not-fakable items which uses “honest” test - “faked response” retest techniques. The authors suggest that attitude inventory items should be selected on the basis of criterion-related validity rather than on that of non-fakability.
