LIDAS as a Valid Measure for Chronic Pain

J Pain; ePub 2018 Aug 30; Wilson, et al

Use of a Limitations in Daily Activities Scale (LIDAS) provided a valid and reliable tool for measuring chronic pain, a new study found. 941 patients with chronic pain completed the 16-item LIDAS at 2 pretreatment and 1 post-treatment assessment points. Individual item analysis favored a 13-item scale. The 13-item LIDAS had a confirmed 3-factor structure consisting of limitations in personal care, global participation, and specific tasks. Among the findings:

  • Reliability analyses for the total scale as well as for each factor individually, indicated good internal consistency, test-retest reliability, and responsiveness to change with treatment.
  • LIDAS scores correlated as expected with measures of pain intensity, pain cognitions, and depression, was well as with other self-report and clinician-administered measures of functional performance.
  • A 5-point change in total scores indicated a clinically important difference.
