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. [ABSTRACT FROM AUTHOR]

The impact of work–family conflict on well-being outcomes is well established, as is the role of social support in buffering perceptions of conflict. What is less well understood is how these relationships vary for different groups of respondents. Using a two-wave longitudinal design with a 12-month time lag and samples of employees (total N = 2183) from Australia, New Zealand, China and Hong Kong, the present research investigated whether the mediating relationships between social support, work–family conflict and well-being outcomes were moderated by gender, geographical region and the presence of dependants in the household. Supervisor support and family support were associated with lower work–family conflict, and hence reduced psychological strain and increased job and family satisfaction, for women and for employees in China and Hong Kong, but not for employees in Australia and New Zealand. However, the presence of dependants was not a significant moderator. Our findings illustrate the importance of exploring gender and national differences in work–family conflict research, particularly the investigation of cross-domain effects. [ABSTRACT FROM AUTHOR]
