The aim was to develop and trial a computer delivered multimedia 1-day physical activity questionnaire (CDPAQ) and to compare this with an equivalent hard copy version (HC). Thirty male and female subjects (1 1.96 ± 0.53 years) were used to assess the validity of the questionnaires by comparing Caltrac counts and heart rate (HR) data with physical activity recalls. Pearson product-moment correlations between the CDPAQ and HR and Caltrac counts ranged from r = 0.36 to 0.63 (p < .05). For the HC, correlations ranged from r = 0.25 to 0.48 (p < .05). While the CDPAQ displayed consistently higher validity correlations, the differences failed to reach statistical significance. Both questionnaires demonstrated high test-retest reliability (r = 0.98, p = .0001). The multimedia features of the CDPAQ may assist children in remembering and characterizing physical activity. The data processing features of the CDPAQ also provide considerable time-saving benefits.
