Pain instrument - PDQQ spine
OBJECTIVE: To evaluate the reliability, validity, responsiveness, and
practicality of a short composite questionnaire designed for use in an
interventional spine pain management setting. SETTING: A rural interventional
spine pain management practice. PATIENTS: Sixty subjects undergoing spinal
intervention procedures (injection or neurotomy). METHODS: The Pain Disability
Quality of Life Questionnaire-Spine (PDQQ-S) assesses spine pain quality, related
disability, and life satisfaction/quality with the use of 2 questions for each
domain. To assess the PDQQ-S, patients completed 4 questionnaires (McGill Pain
Questionnaire [MPQ], Oswestry Disability Questionnaire [ODQ], Assessment of
Quality of Life [AQoL], and PDQQ-S). Patients completed the questionnaires twice
before their procedure and once after their procedure. MAIN OUTCOME MEASURES:
Test-retest reliability was assessed by calculating the Pearson correlation
coefficient for the 2 preprocedure questionnaire completions. Validity was
assessed by calculating the Pearson correlation of the pain quality, disability,
and life quality/satisfaction question scores of the PDQQ-S with the MPQ, ODQ,
and AQoL, respectively. Questionnaire responsiveness was explored by calculating
responsiveness ratio scores. Practicality was assessed by recording the time
required to complete each questionnaire and the ease with which it was completed.
RESULTS: Test-retest reliability correlation scores were as follows: PDQQ-S =
0.73; MPQ = 0.88; ODQ = 0.89; and AQoL = 0.83. Acceptable correlations existed
between the pain, disability, and life quality/satisfaction domains of the PDQQ-S
and the MPQ (.50), ODQ (.71), and AQoL (-.43), respectively. Responsiveness ratio
scores for the PDQQ-S, MPQ, ODQ, and AQoL were 4.4, 1.9, 2.3, and 0.7,
respectively. Compared with the other questionnaires, the PDQQ-S required
approximately one fifth the time to complete and was significantly easier to
understand. CONCLUSIONS: The PDQQ-S demonstrates adequate reliability and
validity and superior responsiveness and practicality in persons with low back
pain undergoing interventional spine pain management procedures.
