Hypothesis

To assess the sensitivity to change of the McMaster Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR) in chronic low back pain (CLBP) and shifts in patients' priorities of disabling activities over time.

Conclusion

The MACTAR is responsive to change in chronic low back pain, but shifts in patient priorities can influence its scores.

Supporting Evidence

  • The MACTAR showed high sensitivity to change with an SRM of 0.66 for patients considering their condition improved.
  • Patients often shifted their priorities, affecting their MACTAR scores.
  • Shifts in priorities were common, with 48 out of 100 patients changing at least one priority.

Takeaway

This study looked at how patients with back pain change what they think is important over time, and how that affects their scores on a questionnaire about their pain.

Methodology

A prospective longitudinal survey of 100 patients with chronic low back pain, evaluated at baseline and 6 months using various questionnaires.

Potential Biases

Potential bias due to self-reported measures and loss to follow-up.

Limitations

The study may not generalize to all chronic low back pain patients as it was conducted in a single tertiary care center.

Participant Demographics

Mean age 54.3 years, 62% female, with a variety of pain-related conditions.
