Takasaki H, Chien C-W, Johnston V, Treleaven J, Jull G. Validity and reliability of the Perceived Deficit Questionnaire to assess cognitive symptoms in people with chronic whiplash-associated disorders. Objective To investigate the validity and reliability of the Perceived Deficit Questionnaire (PDQ) for use in people with chronic whiplash-associated disorders. Design Cross-sectional. Setting Tertiary institution. Participants Patients (N=105) with chronic whiplash-associated disorders and asymptomatic controls (n=50). Interventions Not applicable. Main Outcome Measures The 20-item PDQ inclusive of 4 sections (attention/concentration, retrospective memory, prospective memory, and organization/planning) rated on a 5-point scale. Results Internal construct validity of the PDQ was examined by Rasch analysis, confirming the appropriateness of its 5-point scale and the unidimensionality of each section after modification by eliminating 1 item each from the attention/concentration and retrospective memory sections. Preliminary evidence was also gained for external construct validity (convergent validity) of the modified PDQ by demonstrating significant (P<.05 correlations of all sections with a global measure disability due to neck pain index the whiplash group demonstrated significantly higher scores in each section modified pdq than did control indicating evidence for discriminant validity. addition good internal consistency reliability>.8) and acceptable test-retest reliability with 1-month interval (intraclass correlation coefficients >.8). Conclusions The modified PDQ appears to be a valid and reliable questionnaire and could be used quickly in clinical practice to gain a basic understanding of perceived cognitive symptoms in people with chronic whiplash-associated disorders. |
