So you think you can dance? Dataset for the development and validation of the Dance Self-Efficacy Scale for older adults (DanSES-60+)

Study synopsis: Dance is recommended exercise for older people that benefits health across cultures and socioeconomic groups. Dance self-efficacy may determine program participation, yet measures are limited. This study developed and validated the Dance Self-Efficacy Scale for older adults (DanSES-60+) following systematic procedures. Expert review reduced 60 items to 32 items, which were administered to 289 adults (M age = 72.1 years). The sample was split for exploratory (n=97) and confirmatory (n=192) factor analysis. Item analysis reduced the scale to 12 items with a two-factor structure: Barriers to dancing and dance task self-efficacy. The scale demonstrated good internal consistency (α = 0.95) and test-retest reliability (ICC = .84), and strong validity evidence. Dance self-efficacy scores were significantly associated with dance experience, mobility, health, physical activity, and arts engagement. The DanSES-60+ addresses a critical measurement gap in dance and aging research, and enables participant screening, program evaluation, and investigating mechanisms underlying program effectiveness.

Dataset: Participants are community-dwelling older adults (aged 60+ years) living in Australia, with and without dance experience. The dataset contains responses to 32 prospective dance self-efficacy scale items, dance experience items, participant demographics, self-reported health and health conditions, mobility, falls history, physical activity, and participation in arts and cultural activities. A data dictionary is supplied.

研究概述：舞蹈是适用于跨文化与社会经济群体的老年人推荐运动，对健康具有多方面益处。舞蹈自我效能感可能影响项目参与意愿，但当前相关测评工具较为稀缺。本研究遵循系统流程，开发并验证了适用于老年人的舞蹈自我效能量表（Dance Self-Efficacy Scale for older adults, DanSES-60+）。经专家评审，初始60个条目被精简至32个，并对289名成年人（平均年龄72.1岁）开展施测。将样本划分为探索性因子分析组（n=97）与验证性因子分析组（n=192）。通过条目分析，最终量表精简为12个条目，包含两个因子结构：舞蹈参与障碍与舞蹈任务自我效能感。该量表表现出良好的内部一致性信度（克朗巴赫α系数 (Cronbach's α)=0.95）与重测信度（组内相关系数 (Intraclass Correlation Coefficient, ICC)=0.84），且具备充足的效度证据。舞蹈自我效能感得分与舞蹈经历、活动能力、健康状况、体力活动及艺术参与度显著相关。DanSES-60+填补了舞蹈与老龄化研究领域的关键测评空白，可用于参与者筛选、项目评估以及探究项目有效性的内在机制。

数据集：研究对象为居住在澳大利亚的社区居家老年人（年龄≥60岁），涵盖有舞蹈经历与无舞蹈经历者。数据集包含32项舞蹈自我效能量表条目作答结果、舞蹈经历相关条目作答结果、参与者人口统计学信息、自我报告的健康状况与健康问题、活动能力、跌倒史、体力活动情况，以及艺术与文化活动参与情况。本数据集附带数据字典。
