We used an attitude scale to predict the use of effective contraceptive methods by Turkish women and to determine the appropriate attitude scale cut-off score that would best predict contraceptive use. Participants were 590 married Turkish women who completed a questionnaire developed by the authors and a family planning attitude scale developed by Orsal and Kubilay (2007). We found that the total attitude score could be a diagnostic measure to predict the use of effective contraceptive methods, with a novel cut-off score of 119. If the total score gained on the scale is over 119, the woman will be receptive to information about family planning and use of effective contraceptive methods
