Sample پرسشنامه فعالیت بدنی IPAQ (فرم کوتاه)

What does the IPAQ measure?

Physical activity over the last 7 days in every domain of life (work, home, transport and leisure) at three intensities — vigorous activity, moderate activity and walking — plus time spent sitting on a weekday. It was built for population surveillance of adults, and its protocol recommends it for ages 15 to 69.

Scoring the IPAQ

1. 1.MET-minutes/week = MET × minutes per day × days per week; walking 3.3, moderate activity 4.0 and vigorous activity 8.0 METs. The total is the sum of the three activities.
2. 2.Data cleaning follows the IPAQ protocol (November 2005): times under 10 minutes (and their days) are set to zero, times over 180 minutes count as 180, and if the three daily times add up to more than 960 minutes the response is an outlier and excluded (the “valid response” field is 0 and the MET fields are empty).
3. 3.“High”: vigorous activity on at least 3 days totalling at least 1,500 MET-minutes/week, or 7 or more days of any combination totalling at least 3,000 MET-minutes/week.
4. 4.“Moderate”: 3 or more days of vigorous activity of at least 20 minutes a day, or 5 or more days of moderate activity and/or walking of at least 30 minutes a day, or 5 or more days of any combination totalling at least 600 MET-minutes/week. Anyone not meeting these is “low”.
5. 5.Days of different activities are added together for the 5-day and 7-day criteria (protocol section 7.6); for the “30 minutes of moderate activity and/or walking” criterion this template counts the days of moderate activity and of walking that lasted at least 30 minutes.
6. 6.Sitting time is not part of the score and is reported separately. Differences from the paper form: time is asked in minutes (not hours and minutes) and respondents give their best estimate instead of ticking “don't know”.

Interpreting IPAQ scores

The three levels and their criteria (above) come from the official IPAQ protocol. There are no official thresholds for MET-minutes themselves, and the IPAQ committee recommends reporting medians and interquartile ranges rather than means.

IPAQ validity and reliability

• Craig et al. (2003) tested reliability and validity in 14 centres in 12 countries: test–retest correlations (Spearman) clustered around .8 and criterion validity against accelerometers had a median of about .30 — comparable to other self-report questionnaires.
• The same study recommended the short “last 7 days” form for national monitoring and the long form for more detailed research; the age range tested was 18 to 65.
• The IPAQ protocol does not recommend the short form as an outcome measure in small intervention studies; it is primarily for population monitoring.
