Previous research has studied the relationship between the use of the Elaboration Likelihood Model (ELM) and various personality traits when individuals are presented with persuasive information. This study aims to examine attitude change toward treatment in personality disorder (PD) patients using the ELM. It is predicted that patients of BPD, SPD, and OCPD will be more likely to use the central route of processing, while patients of NPD will be more likely to use the peripheral route of processing when evaluating persuasive information due the personality traits characteristic of the respective disorders. Selected patients of the four PDs of interest will be randomly assigned to read a positive persuasive appeal containing information more likely to be persuasive to an individual using the central route of processing or, conversely, the peripheral route of persuasion. Differences in treatment attitudes before and after reading each appeal will be compared in a 2x4 Factorial ANOVA design. Understanding individual differences in information processing and attitude change toward treatment depending on personality disorder could potentially allow for mental health professionals to consider these tendencies when encouraging treatment for individual personality disorder patients.
