The concept of occupational balance is frequently used in occupational therapy but the fact that it has been defined and measured differently is a limitation. This article introduces the Occupational Balance Questionnaire (OBQ), which focuses on satisfaction with the amount and variation of occupations. It consists of 13 items measured on six-step ordinal scales. It has shown good content validity in a sample of 21 occupational therapists but other psychometric properties have not been investigated. The aim was to investigate the OBQ regarding internal consistency, test-retest reliability, and floor/ceiling effects.
The OBQ was administered twice to a sample selected through convenience sampling. Internal consistency was investigated by Cronbach's alpha and test-retest reliability analysed with Spearman's Rho correlation for the total score and weighted kappa on each item. Potential floor/ceiling effects were explored by checking for the percentage of participants who scored lowest and highest.
The results demonstrated that the OBQ has good internal consistency (Cronbach's alpha 0.936) and sufficient test-retest reliability (Spearman's Rho for the total score was 0.926) and, thus, seems stable over time. No floor or ceiling effect was detected.
The OBQ therefore showed promising reliability, although further instrument development studies to examine its construct validity are required.
职业平衡的概念在职业治疗中经常被使用，但它的定义和测量方式存在差异，这是一个局限性。本文介绍了职业平衡问卷（OBQ），该问卷侧重于对职业数量和多样性的满意度。它由13个项目组成，采用六步顺序量表进行测量。在21名职业治疗师的样本中，它显示出良好的内容效度，但其他心理测量学特性尚未得到研究。目的是调查OBQ的内部一致性、重测信度和地板效应/天花板效应。
通过便利抽样选取一个样本，对其进行两次OBQ测试。通过Cronbach's alpha系数调查内部一致性，用Spearman's Rho相关性分析总分的重测信度，并对每个项目进行加权kappa分析。通过检查得分最低和最高的参与者的百分比来探索潜在的地板效应/天花板效应。
结果表明，OBQ具有良好的内部一致性（Cronbach's alpha系数为0.936）和足够的重测信度（总分的Spearman's Rho相关性为0.926），因此，随着时间的推移似乎是稳定的。未检测到地板效应或天花板效应。
因此，OBQ显示出有前景的信度，尽管需要进一步的工具开发研究来检验其结构效度。
