Considerations

  • ORQ may have implications for evaluating back pain intervention programs
  • Distribution of responses observed suggests that the four-point response format cold probably be reduced to a three-point scale
  • Psychological variables are not included in ORQ

Cut-Off Scores

Back pain: (Kopec, J. A., & Esdaile, J. M. (1998); n = 137)

To study the effects of sociodemographic variable and type of job on occupational role performance, the groups in terms of mean scores were initially compared. However, because the scores were strongly skewed, the score of 75/100 or less was used as a cut-off point. Contingency tables were used to assess these effects.

Normative Data

Back pain: (Kopec, J. A., & Esdaile, J. M. (1998); n = 137; 69 male participants, 68 female participants; participant age, 24.8% under 30 years, 26.3% 30-39 years, 29.9% 40-49 years, 19.0% 50+ years; 59.9% English speakers; 51.8% university education level; lifting required at work, 47.2% no, 40.2% sometimes, 12.6% often)

Test/Retest Reliability

Back pain: (Kopec, J. A., & Esdaile, J. M. (1998); n = 137)

  • Subsample of 56 subjects who answered the questionnaire twice over a period of up to 2 weeks, and who reported no change in back pain between the two assessments)

Construct Validity

Back pain: (Kopec, J. A., & Esdaile, J. M. (1998); n = 137)

  • External construct validity was studied by examining correlations of the ORQ with a seven-point scale of pain and with the Roland and Morris Disability Scale

Content Validity

Back pain: (Kopec, J. A., & Esdaile, J. M. (1998); n = 137)

  • Occupational role items were part of a larger questionnaire that included, inter alia, the TyPE Low Back Pain Form, Roland and Morris Disability Scale, and basic sociodemographic information
  • The questionnaire was pilot-tested on a sample of 23 back pain patients
  • The English version of the questionnaire was translated to French and then back translated to English.

16 original items were analyzed, based on these results two sub scales of occupational role performance were derived, with four items in each scale.
