Occupational balance, a foundational concept in occupational therapy and science, plays a critical role in enhancing health and well-being. Recent studies have revealed its association with epidemiological factors. This study evaluated the validity and reliability of the Japanese version of the Occupational Balance Questionnaire 11 (OBQ11-J).
Adhering to the COnsensus-based Standards for the selection of health Measurement INstruments and Rasch Reporting Guidelines for Rehabilitation Research, analyses were conducted on the OBQ11-J using a cohort of 462 generally healthy individuals.
The mean OBQ11-J score was 17.7 ± 5.1, ranging from 2 to 33. Two items (Items 1 and 9) exhibited ceiling effects. The 4-point rating scale was validated. Although two items (Items 1 and 10) did not strictly conform to the Rasch model, the overall one-dimensionality and single-factor structures were supported. This confirms the structural validity of the OBQ11-J with its 11 items and 4 rating stages. Reliability, assessed through internal consistency, person separation reliability and test-retest reliability, further affirmed the instrument's robustness.
The OBQ11-J demonstrated validity and reliability in a sample of healthy Japanese individuals. Future investigations should establish normative values for the Japanese population and examine criterion-related validity, responsiveness and interpretability.
职业平衡是职业治疗与科学中的一个基础概念，在增进健康和福祉方面发挥着关键作用。近期研究揭示了它与流行病学因素的关联。本研究评估了日语版职业平衡问卷11（OBQ11-J）的有效性和可靠性。
遵循基于共识的健康测量工具选择标准以及康复研究的拉施报告指南，对462名一般健康个体组成的队列使用OBQ11-J进行分析。
OBQ11-J的平均得分是17.7±5.1，范围为2至33。两个项目（项目1和项目9）呈现出天花板效应。4点量表得到了验证。尽管两个项目（项目1和项目10）不完全符合拉施模型，但总体的单维度性和单因素结构得到了支持。这证实了包含11个项目和4个评分阶段的OBQ11-J的结构有效性。通过内部一致性、人员分离可靠性和重测可靠性评估的可靠性，进一步证实了该工具的稳健性。
OBQ11-J在健康日本个体样本中表现出有效性和可靠性。未来的研究应确定日本人群的常模值，并检验效标关联效度、反应度和可解释性。
