BACKGROUND
Considering the importance of health behaviors in health outcomes, it is necessary to assess health behaviors precisely. This study aimed to develop and validate The Geriatrics Health Behavior Questionnaire among Iranian older adults.
METHODS
This cross-sectional and methodological study was conducted on 420 community older adults (age ≥ 60) through random multi-stage sampling. The initial questionnaire has been developed with 22 items and seven subscales based on an extensive literature review, evaluation of related questionnaires, and experts' opinions. Face and content validity were evaluated by interviewing 10 older adults and 18 specialists. The construct validity was evaluated via Known-groups validity and convergent validity. The reliability of the questionnaire was calculated by internal consistency, test-retest, and absolute reliability.
RESULTS
The face validity was conducted by using interviews with older adults and gathering the specialists' opinions. The items were grammatically and lexically corrected accordingly. Two items were deleted due to CVR < 0.44. Modified Kappa statistic (K*) and I-CVI for all items were higher than 0.88. The average content validity index (S-CVI/Ave) value was 0.94. Three items were deleted to improve the internal consistency; the final GHBQ consisted of 17 items with Cronbach α = 0.72. Acceptable convergent validity was approved by a significant correlation between GHBQ and SF8™ health survey (r = 0.613, P value< 0.001). Independent t-test showed that older adults with education level ≥ high school have significantly higher health behavior scores than those with education level < high school (11.93 ± 2.27 vs. 9.87 ± 2.35, t = - 9.08, p < 0.001). Intra-class correlation coefficient (ICC) for the total questionnaire was 0.92 (95% CI =0.84 to 0.96). Standard Error Measurement (SEM) and Minimal Detectable Change (MDC) were 0.71 and 1.98, respectively.
CONCLUSION
The present study results showed that the Geriatrics Health Behavior Questionnaire had suitable validity and reliability among Iranian older adults. It is recommended to consider its comprehensiveness and yet its briefness in other populations after passing validation.
背景
鉴于健康行为对健康结果的重要性，精确评估健康行为很有必要。本研究旨在编制并验证伊朗老年人的老年健康行为问卷。
方法
本横断面及方法学研究通过随机多阶段抽样，对420名社区老年人（年龄≥60岁）进行。初始问卷基于广泛的文献综述、相关问卷评估及专家意见编制而成，包含22个条目和7个分量表。通过对10名老年人和18名专家进行访谈来评估表面效度和内容效度。通过已知群体效度和收敛效度评估结构效度。问卷的信度通过内部一致性、重测法和绝对信度来计算。
结果
通过对老年人进行访谈并收集专家意见来进行表面效度评估。相应地对条目进行了语法和词汇方面的修正。由于内容效度比（CVR）<0.44，删除了两个条目。所有条目的修正卡方统计量（K*）和I-CVI均高于0.88。平均内容效度指数（S-CVI/Ave）值为0.94。为提高内部一致性删除了三个条目；最终的老年健康行为问卷（GHBQ）由17个条目组成，Cronbach α系数为0.72。GHBQ与SF8™健康调查之间存在显著相关性（r = 0.613，P值<0.001），证明了可接受的收敛效度。独立t检验表明，教育水平≥高中的老年人健康行为得分显著高于教育水平<高中的老年人（11.93±2.27对9.87±2.35，t = -9.08，p <0.001）。问卷总量表的组内相关系数（ICC）为0.92（95%置信区间=0.84至0.96）。标准误测量（SEM）和最小可检测变化（MDC）分别为0.71和1.98。
结论
本研究结果表明，老年健康行为问卷在伊朗老年人中具有良好的效度和信度。建议在经过验证后，考虑其在其他人群中的全面性和简洁性。
