Background: The Profile of Pragmatic Impairment in Communication (PPIC) is a clinical rating scale designed for the assessment of multiple facets of pragmatic language impairment in neuropsychiatric disorders. The PPIC has its origin in Grice's analysis of implicature and the Gricean principle of co-operation and conversational maxims. Aims: We sought to evaluate the psychometric properties of the PPIC and to generate a profile of pragmatic language impairment associated with Alzheimer's disease (AD). Methods & Procedures: Speech samples were solicited from patients with AD (n = 13) and age-matched healthy volunteers (n = 13) using several structured/semi-structured tasks. Three trained raters made blind ratings on the PPIC on two occasions. Other raters evaluated mental status, aphasia, and communicative effectiveness. A generalisability analysis was conducted. Outcomes & Results: Good to excellent generalisability coefficients (0.86-0.94) were observed on most PPIC scales. PPIC ratings were strongly related to mental status and communicative effectiveness but not associated with aphasia. Diagnosis of AD made no substantive contribution to the prediction of PPIC ratings independently of mental status impairment. Conclusions: Results demonstrate evidence of good to excellent reliability, convergent validity, and discriminant validity of most PPIC scales. The observed associations are consistent with the view that pragmatic language impairment in AD is primarily a function of cognitive decline. |
