PMID 28174459WHAT IT FOUND
Scores from a five-item leisure activity questionnaire were stable when adults answered again after 1 to 2 months.
The paper did not compare the questionnaire with objective devices.
Key findings
01The five questions together measured one kind of habitual leisure physical activity.
02Scores were stable when people answered again after 1 to 2 months.
03The questionnaire was not compared with an objective device such as an accelerometer.

What it does not show
The paper describes adults aged over 20 but reports an age range of 12 to 95 years, so the sample description is inconsistent. The authors did not perform concurrent validity by comparing questionnaire scores with an objective device such as an accelerometer. The retest was administered to 382 respondents, while 334 were unavailable, so the stability result may not represent all original respondents. The text says the retest interval ranged from 1 month to 2 months, but Table 2 includes a 3-month lag for one sample, so the timing is not fully clear. The sample was recruited from community recreational centres in Gyeongsan, South Korea, not from a clinical patient group.

The easy way to misread this
Do not treat the five-item questionnaire as a validated clinical measure of physical activity. The authors did not compare its scores with an objective device such as an accelerometer, so its accuracy against real movement was not tested.
