| Sumario: | Objective: To assess the effectiveness of health screening interventions aimed at enhancing informed choice. Methods: Studies were selected if (1) they were randomized controlled trials conducted between January 1, 2000, and March 30, 2010, (2) participants in one arm underÂwent a prescreening intervention aimed at improving informed choice, and (3) inÂformed choice was the primary outcome. Results: Eight studies that met the inÂclusion criteria involved screening for prostate, colorectal and breast cancer, and diabetes. Five of the 8 prescreenÂing interventions led to greater informed choice. Conclusions: With researchers mindful of the limited number of studÂies, findings were encouraging, but conÂclusions regarding the most effective ways of facilitating informed choice for screening are at best tentative.
