Abstract
Introduction
Sensory profiles classified in Low Registration, Sensory Sensitive, Sensation Avoiding and Sensation Seeking may be used in patients with non-specific chronic low back pain (CLBP) to develop a more personalized treatment program. Although psychometric properties have not been studied up till now the Adult Adolescent Sensory Profile (AASP) can be used to measure sensory profiles in CLBP patients.
Objectives
The study aim was to asses internal consistency, test-retest reliability, agreement and construct validity of the AASP in a CLBP population with nociplastic pain.
Method
A non-experimental, cross-sectional study design was used, with two measurements with a two weeks interval. All self-reported questionnaires were used at t0 and t1 to assess outcome in comparison to the AASP and SP. Reliability was evaluated by assessing internal consistency and test-retest reliability. To assess construct validity, the a priori hypothesis on the four profiles, correlation was analyzed.
Results
Ninety CLBP patients were included, with a mean duration of CLBP of 232 weeks. Internal consistency for each sensory profile, Cronbach's alpha varied from 0.91 to 0.92. Test-retest reliability varied from intra-class correlation coefficient (ICC) 0.90–0.92. Construct validity correlated positively between sensory profiles, Low Registration, Sensory Sensitive and Sensation Avoiding, and negatively with Sensation Seeking.
Conclusion
The AASP is considered to be a suitable instrument for measuring sensory profiles in CLBP patients in primary care.
