Abstrakt: Aim: The present study aimed to assess the sensitivity, specificity and construct validity of the General Practice Physical Activity Questionnaire (GPPAQ) and two modified versions, GPPAQ-WALK and GPPAQ-WALK-Old in retired, community-dwelling older adults, 60–90 years. Methods: Participants completed assessments from the Senior Fitness Test (lower limb strength, dynamic balance, aerobic endurance) and used a waist-worn accelerometer for a week, following which they responded to the GPPAQ. Active/non-active GPPAQ classification was compared against accelerometry regarding meeting/not meeting the guidelines of ≥ 150 min/week of moderate-to-vigorous physical activity (MVPA). Sensitivity and specificity were calculated. T tests compared BMI and fitness scores between active and non-active participants. Results: A total of 180 retired adults residing in Greece, mean age 72.82 ± 6.30, participated in the study, 114 of whom had valid accelerometer data corresponding to the GPPAQ recall week. The GPPAQ active classification showed 4.4% sensitivity and 97.4% specificity but did not differentiate active and non-active participants regarding BMI and physical fitness. The GPPAQ-WALK showed 27.8% sensitivity and 80.8% specificity, with active participants performing better in dynamic balance and lower limb strength than non-active. The GPPAQ-WALK-Old showed 69.4% sensitivity and 44.9% specificity. Active participants had lower BMI, better lower limb strength and dynamic balance than non-active. Conclusion: With an interest in increasing awareness of the importance of PA and improving public health outcomes through PA promotion in insufficiently active older adults, we advocate that the GPPAQ-WALK can be a useful tool in healthcare and other community settings. Further modifications to fully assess adherence to PA guidelines for older adults are proposed.
