title: Psychometric evaluation of the Energy Conservation Strategies Survey.
abstract: OBJECTIVE
  To examine the internal consistency and test-retest reliability of the Energy Conservation Strategies Survey (ECSS), a tool that was specifically designed to determine if people with multiple sclerosis who attended the six-week energy conservation course actually implemented the strategies taught to them.
  
  
  METHODS
  The instrument ECSS was administered at six weeks and seven weeks post intervention to evaluate the test-retest reliability, while data from six weeks post intervention were utilized to assess the internal consistency of the ECSS.
  
  
  METHODS
  Community locations in Illinois and Minnesota, USA.
  
  
  METHODS
  Data from 53 participants with multiple sclerosis living in the community were utilized for the psychometric study.
  
  
  METHODS
  Energy Conservation Strategies Survey.
  
  
  RESULTS
  The internal consistency of 0.92 reveals that all the items are consistent with each other and measure a single construct. Inferential analyses using intraclass correlation coefficient indicates good test-retest reliability (intraclass correlation coefficient (ICC) = 0.79).
  
  
  CONCLUSIONS
  Findings of the study suggest that the ECSS exhibits high internal consistency and good test-retest reliability. The study implies that the ECSS could be valuable in measuring changes in behaviour over time among people with multiple sclerosis after the completion of the six-week energy conservation course provided by occupational therapists.
