The 82.5% of the study sample was treated with laxatives, and a 59.9% of the sample was practicing enema. The average score of the ADL was 38.32(range: 0 - 100). According to surveying on the ADL in relation to the function of the constipation, ADL is found to be higher in the non-constipation group than the constipation group (t=-2.786, p=.006).
