Limitations
The PAI is a self-report instrument. Self-report is one of many methods for psychological assessment, and thus relies on the individual taking the assessment to answer honestly. The PAI does not measure some constructs that might be of concern in clinical assessment (e.g., eating disorders), it is often useful to supplement the PAI with other measures for this reason as well. Caution should be exercised in interpreting PAI data from non-English speakers or when administration breaks from the standardized (self-administration) process. Boyle and Lennon (1994) expressed concerns about the measure's reliability and construct validity in a study of 211 participants, including 30 individuals with alcoholism and 30 individuals with schizophrenia. PAI-A scales do not correspond directly with DSM categories.

Famous quotes containing the word limitations:
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
“No man could bring himself to reveal his true character, and, above all, his true limitations as a citizen and a Christian, his true meannesses, his true imbecilities, to his friends, or even to his wife. Honest autobiography is therefore a contradiction in terms: the moment a man considers himself, even in petto, he tries to gild and fresco himself.”
—H.L. (Henry Lewis)
