This study was conducted to determine the effects of an algorithm training booklet, which was based on Orem’s self-care deficit nursing theory, specific to lower extremity peripheral artery disease, on pain, activities of daily living, self-care agency, walking distance, quality of life, and other symptoms. This mixed-method study included a qualitative stage using face-to-face in-depth individual interviews and a pretest–posttest semiexperimental design quantitative stage. In-depth interviews were conducted to highlight self-care needs and symptoms and to create the booklet. The booklet’s content was prepared in line with concepts of Orem’s theory. The patients were educated with the direction of the booklet and evaluated on outcomes. The data were evaluated using percentage distribution, means, Mann-Whitney U test, and Friedman test. Three categories were identified through the thematic analysis. It was determined that patients had lower pain score and higher activities of daily living, self-care, walking distance, and quality of life scores after the training.
