Are Multimorbidity and Related Factors Associated With Non-response Bias in Patients With Spinal Pain?

Sponsor: Jacob Christiansen Gandløse

Summary

The study aims to explore if non-response bias exists among individuals with chronic back pain, focusing on the impact of chronic disease count, treatment burden from multimorbidity, and health-related quality of life. Data is gathered from patients at Aalborg University Hospital's Rheumatology Department via electronic means and medical records. The analysis comprises two-wave assessments, investigating disparities among patients responding to study invitations based on response patterns: first, second, or third invitation responses. Utilizing baseline data, a one-way ANOVA is employed to detect potential between-group variations in the mentioned factors. Subsequently, a repeated measures ANOVA is conducted to evaluate differences among groups over time. Additionally, statistical analyses are conducted to scrutinize variances in age and gender distribution between respondents and non-respondents to the questionnaire invitations at baseline.
