TITLE: Comparing Single Question Physical Activity Questionnaire With Common Assessments of Physical Activity in Older Adults CURRENT SECTION: Geriatrics AUTHORS: Jerneja Uhan, Julia M. Wright, Jane Freund, Chitra Lakshmi K Balasubramanian, Srikant Vallabhajosula ABSTRACT BODY: Purpose/Hypothesis: Long questionnaires which consist of several validated tools typically provide an overbearing experience. Also several of the available validated tests are subjective in nature. Recently the Single Question Physical Activity Questionnaire (SinglePAQ) was developed and validated to be used to assess physical activity. However, it is currently not known how the results of this self-reported single question compare to those that are routinely used to assess physical activity among older adults. Therefore, our purpose was to compare the SinglePAQ with established subjective and objective assessments of physical activity among older adults. Number of Subjects: 30 community-dwelling older adults, comprising of 13 men and 17 women with a mean age of 73 (+/− 6.6) years. Materials and Methods: Participants completed the SinglePAQ and the Community Health Activities Questionnaire for Older Adults (CHAMPS). Both these questionnaires have been validated to be used in community-dwelling older adults. The SinglePAQ consisted of a single question on a Likert scale about the participant’s perception of their physical activity in the past 6 months. The CHAMPS questionnaire consists of 41 questions related to physical activity within the past month. The frequency of all exercise related activities completed in a week from CHAMPS was used for data analysis. Objective assessment of physical activity was done using StepWatch, a research-grade step activity monitor (SAM). Participants wore SAM for a week on their ankles and average of the total number of steps per day for 7 days were used for data analysis. Spearman’s correlation was used to assess the relationship between objective and subjective tests. Results: There was a significant moderate relationship between the SinglePAQ and CHAMPS (spearman’s rho = 0.43; p = 0.016). However, a weak non-significant relationship was found between the SinglePAQ and SAM (spearman’s rho = 0.30; p = 0.115). There was a significant moderate relationship between the SAM and CHAMPS (spearman’s rho = 0.40; p = 0.030). Conclusions: Results from the current study indicate that SinglePAQ, CHAMPS and SAM may not be assessing physical activity levels in older adults in a similar manner. This could be due to different time periods under each assessment (6 months for SinglePAQ, 1 month for CHAMPS and 1 week for SAM). Subjective and objective assessments of physical activity cannot be used inter-changeably, and researchers and clinicians should be prudent about how they use these measures in older adults. Future studies need to examine the association of SinglePAQ with fall-risk level in older adults. Clinical Relevance: Assessment of physical activity levels among older adults is important due to multimodal benefits including minimizing fall risk, cardiovascular health and functional mobility. Results of the current study indicate that there is a difference between interpretation of subjective and objective techniques to assess physical activity. This could be critical in evaluating physical activity levels in a geriatric clinical setting. Use of SinglePAQ though less time consuming, may not encompass a holistic physical activity assessment.
