Abstract: Psychologists providing clinical services in private practice and many agencies settings now are required to assign psychiatric diagnoses utilizing the ICD-system, rather than the DSM. We focus on the implications for psychologists regarding one particular diagnosis that is common to both classification systems: Post-traumatic Stress Disorder (PTSD). The present article possesses a two-fold purpose: (1) Inform the reader regarding potential difficulties that arise regarding differing PTSD diagnostic criteria in the DSM-5 and ICD-10-CM and (2) Advocate that practitioners take some suggested steps in order to help alleviate unnecessary patient stress that results from the present dilemma. On a macro-level, we advocate for APA and WHO to reconcile the present differences in the upcoming edition of ICD-11. We also note that, until such resolution occurs, significant potential exists for both general patient confusion to occur and also for some patients to “game” the present system between the DSM-5 and ICD-10-CM in order to achieve their desired ends.
