Others' Deception Attitude Measure: Investigating its Psychometric Properties

Many people hold negative attitudes toward others who lie (Curtis, 2013; Curtis, 2015; Curtis & Hart, 2015; Curtis, Huang, & Nicks, 2015). Recently, a scale has been developed to measure attitudes toward others who employ deception, referred to as the Others' Deception Attitude Measure (ODAM; Curtis & Dickens, 2016). The ODAM is an adaptation of the Therapists' Attitudes Towards Deception Scale (TATDS) and Attitudes Toward Patient Deception Scale (ATPDS) and has been used in research investigating therapists attitudes toward client deception and nursing students' attitudes toward patient deception (Curtis, 2015; Curtis & Hart, 2015). The TATDS and ATPDS consisted of 44 items which assessed attitudes towards patients/clients who lie. The TATDS had high internal consistency reliability (alpha = .83) as well as the ATPDS (alpha = .88). The ODAM consist of two subscales (specific and global attitudes) containing 23 of the 24 items from the TATDS and ATPDS that assesses attitudes toward deception. The ODAM changes the wording of patient or therapist to person. The purpose of the current study is to exam the psychometric properties of the ODAM. The inter item reliability and test-retest reliability of the ODAM will be explored. The ODAM will also be compared to other measures to explore its convergent validity and compared to a theoretically unrelated measure to explore its discriminate validity.
