| Abstract | 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 (MDC95) 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. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
