In the tailored condition, 30/43 (70{\%}) participants requested the computer-tailored step advice and the majority found it understandable (21/21, 100{\%}), credible (17/18, 94{\%}), relevant (15/18, 83{\%}), not too long (13/18, 72{\%}), instructive (13/18, 72{\%}), and encouraging to increase steps (16/24, 67{\%}). Daily step counts increased from baseline (mean 9237, SD 3749 steps/day) to postintervention (mean 11,876, SD 4574 steps/day) in the total sample (change of 2639, 95{\%} confidence interval 105--5172; F1 = 5.0, P = .04). No interaction or other time effects were found. Conclusions : The majority of participants in the tailored condition accepted the step advice and indicated it was useful. However, in this selected sample of adults, the tailored condition did not show superior effects compared with the standard condition.
