title: Development of an evaluation scale for self-management behavior related to physical activity of patients with coronary heart disease.
abstract: BACKGROUND
  To provide patients with effective self-management education that takes their lifestyle into account, medical personnel need to provide education and evaluation of self-management behaviors which patients can apply to their daily life.
  
  
  OBJECTIVE
  This study aimed to assess the reliability and validity of the evaluation scale for self-management behavior related to physical activity of patients with coronary heart disease (ES-SMBPA-CHD).
  
  
  RESULTS
  Outpatients with coronary heart disease (n = 76) completed a self-administered questionnaire supported by a previous study of ours. The ES-SMBPA-CHD was divided into two domains, the first dealing with self-management behavior to enhance physical activity in daily life and the second with behavior to maintain the level of physical activity. Factor analysis showed that the first part comprised four factors and the second five. The ES-SMBPA-CHD was associated with the International Physical Activity Questionnaire (IPAQ) subscales and activity energy expenditure (measured by Lifecorder EX). Cronbach's α coefficient was between 0.71 and 0.90. The intraclass test-retest correlation coefficient of the subscale was between 0.75 and 0.93.
  
  
  CONCLUSIONS
  The ES-SMBPA-CHD is reasonably reliable and valid and is expected to prove useful for the assessment of patients' self-management behavior and for individualized instruction.
