Lec 3: PA & Sedentary Behaviour Questionnaires

Question 1

GUIDE for selecting PA Questionnaire

1-9

Answer 1

1 PURPOSE - clearly defined
2 CONSTRUCT - matches your construct (beh. etc) with measurement
(overall vs spec setting vs spec dimension (type of PA))

3 MEASUREMENT UNIT - depends on research Q
(ex: light, mod, vig PA/ METs)

4 RECALL PERIOD - day/wk/month/year
(during typical week = habitual PA - may assess more current PA)

5 SETTING - context (leisure time, transport, household)
6 STUDY POP - validity/reliability - important to be reported for spec pop
(age, sex, gender, culture) Ex Elderly = pop, then use measure for elderly ppl

7 MEASUREMENT QUALITY - validity (content, face…
- Reliability (test-retest - relevant)
- (Internal Reliability - are answers similar - less relevant to get PA beh)
: PA measure tends to be a combined measure
- All PA is different/not homogeneous (play bball not soccer)

8 FEASIBILITY/EASE OF USE
- phone, online, clear instruction, no burden, easy to interpret

9 RESOURCES
- of researcher & participant (time, money)

Question 2

PA Questionnaires...
1 IPAQ =
-
-
- 4 options
age -

LONG version looks at…
SHORT version looks at…

Answer 2

1 International Physical Activity Questionnaire

• can look btw different countries
• assess in LAST 7 days
• 1 phone 2 self-admin 3 long 4 short version

Age - 15 - 69 yrs old

L… work, transport, domestic&yard work, leisure -time PA
+ Time spent sitting
[27Q’s]

S... Vig PA ( # days / duration) - 8 MET
Mod PA ( # days / duration) - 4 MET
 Walking ( # days / duration) - 3.3 MET
Sitting on weekdays (duration)
\+ work, transport, domestic, leisure PA

Has a scoring protocol in graph like form - multiplies freq x duration x MET (based on intensity) = Total PA score (MET mins per wk)

Then go to interpretation chart for results

Question 3

2 GPAQ =

• developed by
• for
• administered how
• PA domains covered

Answer 3

2 = Global PA Questionnaire
- by WHO
- for adults
- by face to face interview
- domains are work, transport, leisure + sed beh
\+ PA in TYPICAL week

Question 4

3 PA Recall Questionnaire
ex: recall last 7 days

EX Jane on Slide 19

Answer 4

• list of common activities & ‘others’
• whether did the activity
• if YES, # of days
• on avg # of min (on days the activity was done)
• go to compendium of PAs - look at assigned MET value
• MET-mins/wk for MVPA (from compendium)

EX - 60 min basketball game = 60min x 8MET = 480MET min

Question 5

4 Godin & Shephard Leisure Time PA

• administered…
• MET values are…

Scoring:
Interpretation of score:
Limitations:

Answer 5

• self- administered
• typical 7 day
• exercise for more than 15 min in leisure time
• MET values are different from other questionnaires
  (strenuous = 9) (mod = 5) (mild = 3)

:
- combines M +VPA first THEN adds Mild on top of
Frequency of each category x MET value
EX: 3 x /wk strenuous x 9 = 27 units

: Interpretation of scores, using only moderate &
strenuous PAs -> refer to table

: Q’s ask about exercise which is more structured
not meaningful results without table
what is the 15 min bouts based on?
What is it meant by times / wk? (if 30min is done - is it 2x 15min or)

Question 6

5 Behavioural Risk Factor Surveillance System Questionnaire

• developed by
• for who
• done how and how often
• how is data used
• what does the questionnaire ask?
• use frame of reference for multiple Q’s goes Spec -> General

Answer 6

• CDC
• adults
• phone survey - yearly
• US states use data for public health, emerging health problems, look at comparing to objectives
• asks more than PA (nutr, smoking) = lifestyle as a whole

Question 7

6 Youth Risk Beh Surveillance System Survey

• developed by
• for
• how administered
• how often
• frame of reference

Answer 7

• CDC
• for youth (Grade 9 -12)
• self-administered - during past 7 days
• every 2 years
• at least 1 hr

Question 8

Sedentary Questionnaires…
most focus on:

Answer 8

: frequency, duration, type (screen time vs transit)
- intensity is unnecessary

• separates weekday from weekend
• 9 different response categories of sed activities
• add up total hrs of each category

Question 9

2 Sed Beh Questionnaire (SIT-Q-7d)

- avg in last…

Answer 9

• … 7 days
• in different settings: work, transport, meals, screen time, other leisure
• sitting or laying down etc.
• how long did you sit for meals - avg over 7 days

Question 10

3 PAST =

- Q’s about

Answer 10

= Past Day Adults Sed Time

• about sed beh on previous day
• amt of time spent sitting/lying down when doing 7 activities: work, transport, screen time (TV, computer) reading, hobbies, other purposes
• add it up
