The Physical Activity Questionnaire for Elderly Japanese (PAQ-EJ) is a self-administered physical activity questionnaire for elderly Japanese; the authors report here on its repeatability and direct and indirect validity. Reliability was assessed by repeat administration after 1 month. Direct validation was based on accelerometer data collected every 4 s for 1 month in 147 individuals age 65-85 years. Indirect validation against a 10-item Barthel index (activities of daily living [ADL]) was completed in 3,084 individuals age 65-99 years. The test-retest coefficient was high (r = .64-.71). Total and subtotal scores for lower (transportation, housework, and labor) and higher intensity activities (exercise/sports) were significantly correlated with step counts and durations of physical activity <3 and >or=3 METs (r = .41, .28, .53), respectively. Controlling for age and ADL, scores for transportation, exercise/sports, and labor were greater in men, but women performed more housework. Sex- and ADL- or age-adjusted PAQ-EJ scores were significantly lower in older and dependent people. PAQ-EJ repeatability and validity seem comparable to those of instruments used in Western epidemiological studies.
"The criterion validity of the IPAQ, as indicated by the Spearman correlation coefficient, was 0.30 in 12 countries,11 0.38 in Japanese,22 0.33 in Chinese,5 and 0.29 in Norwegians.24 In criterion validity studies of PA questionnaires for elderly adults, the Spearman correlation coefficients were 0.41 in Japanese4 and 0.37 in Americans.15 In our study, the Spearman correlation coefficients between the original IPAQ and TPA-AC ranged from 0.42 to 0.53, which is comparable with previously published data on IPAQ and PA questionnaires for elderly persons, indicating that the IPAQ has adequate validity for elderly adults.

[Show abstract][Hide abstract] ABSTRACT: The International Physical Activity Questionnaire (IPAQ) is a self-reported questionnaire for assessing physical activity and has been tested in 12 countries among adults aged 18 to 65 years. The present study evaluated the reliability and validity of the IPAQ among adults aged 65 years and older.
The study included 164 men and 161 women selected from participants of the Fujiwara-kyo Study, a prospective cohort of elderly Japanese adults. To examine test-retest reliability, the participants were asked to complete the IPAQ twice, 2 weeks apart. The criterion validity of the IPAQ was tested by using an accelerometer.
Based on intraclass correlation coefficients, the reliability of the total IPAQ was 0.65 and 0.57 for men and women, respectively, aged 65 to 74 years and 0.50 and 0.56 for those aged 75 to 89 years. The Spearman correlation coefficients between total IPAQ score and total physical activity measured by accelerometer (TPA-AC) were 0.42 and 0.49 for men and women, respectively, aged 65 to 74 and 0.53 and 0.49 for those aged 75 to 89. Weighted kappa coefficients between total IPAQ score and TPA-AC were 0.49 and 0.39 for men and women, respectively, aged 65 to 74 and 0.46 and 0.47 for those aged 75 to 89.
The reliability of the IPAQ was not sufficient, but the validity was adequate. Although there were some limitations with regard to repeatability and agreement in classification, the IPAQ was a useful tool for assessing physical activity among elderly adults.

[Show abstract][Hide abstract] ABSTRACT: This study examined the impact of playing Nintendo Wii on the psychological, social and physical well-being of elders. Based on the unique features of Wii, we also explored the possible mediation effects that social interaction and physical activity that playing Wii had on psychological well-being. Finally, we studied how the benefits of playing Wii may be magnified under different playing conditions. A six week-long intervention was held in SASCO Senior Citizens’ Home, a long-term care facility in Singapore. 45 residents aged between 56 and 92 years old took part in the study. Participants were split into three experimental groups: (1) Multiplayer Wii group (2) Single-player Wii group and (3) control group, who played traditional group games. Game sessions took place three times a week, lasting one and a half hours each. Questionnaires were administered through face-to-face interviews before and after the intervention. Measures included social interaction, physical activity, senior centre belonging, loneliness, affect and self-esteem. Results showed that playing Wii had a positive impact on the overall well-being of the elderly. Mediation effects were found for psychological well-being variables like loneliness and belonging. The elder in the single-player Wii group exhibited more positive affect compared to those in the multiplayer group. Through this study, Wii was proven to have a positive contribution to the overall well-being of the elderly. Explanations and implications for future applications of Wii in interventions for the elderly are were discussed. COMMUNICATION STUDIES
[Show abstract][Hide abstract] ABSTRACT: In the current study, we examined the impact of playing Nintendo Wii games on the psychological and physical well-being of seniors in a long-term care facility. A six week-long intervention was held in SASCO Senior Citizens' Home, a long-term care facility in Singapore. Forty five residents aged between 56 and 92 years old participated in the longitudinal field experiment. Results showed that playing Wii games had a positive impact on the overall well-being of the elderly, compared to a control group that played traditional board games. Implications for future applications of Wii in interventions for the elderly are discussed.
