Abstract: BACKGROUND: It is unknown whether questionnaires measuring psychosocial constructs related to low back pain (LBP) that were originally designed for adults are suitable for adolescents, and if paper and web-versions have similar measurement properties. OBJECTIVES: To examine selected psychometric properties for the paper- and web-based Back-Beliefs Questionnaire (BBQ) and the Fear Avoidance Beliefs Questionnaire (FABQ-phys) among adults and adolescents in two diverse countries and to determine whether differences existed between countries and pain groups. METHODS: A sample of 156 adults (Hong Kong, n= 75; Australia, n= 81) and 96 adolescents (Hong Kong, n= 61; Australia, n= 35) participated in this cross-sectional study. RESULTS: Main effects for country and administration mode were observed in adult BBQ scores, where Australian adults reported significantly higher BBQ scores than Hong Kong adults (mean difference (MD); 95% CI: 2.85; 0.96-4.74) and significantly higher scores were recorded on the web mode compared to the paper mode (MD 0.74; 0.10-1.38). Similarly, Hong Kong adults and adolescents reported higher FABQ-phys scores than Australian adults and adolescents (MD; 95% CI: 3.40; 1.37-5.43 and 4.88; 0.53-9.23, respectively). Internal consistency values were mostly acceptable (α ≥ 0.7). CONCLUSION: Differences exist between cultures for LBP-related beliefs. The BBQ and FABQ-phys have acceptable measurement properties in both administration modes.
