Today’s post comes from researchers Salomé Aubert and Fabien Rivière, and describes their recent review of the content of sedentary behaviour questionnaires. More on Salomé and Fabien can be found at the bottom of this post. Their full paper is available for free here.
Sedentary behaviours (SB) are defined as “as any waking behaviour characterized by an energy expenditure ≤1.5 METs while in a sitting, reclining or lying posture” . Health effects of sedentary time have been studied over the past decade with most studies showing negative associations between sedentary time and health outcomes in both adults and youth [2–4]. Much of the evidence for these results has been provided by self-report  with the majority of the studies measuring television (TV) viewing or total sitting time derived from a single question [4,5].
Measuring TV viewing or total sitting time may not provide enough information to understand the health effects of SB. An individual can engage in different types of SB including TV viewing, using a computer, reading, writing, and eating which have several purposes including work, transportation, and leisure time. Some studies have shown that the associations between SB and health-related outcomes vary by the characteristics of the SB measured and in the manner in which sedentary time is accumulated [6–8]. To advance knowledge of the effects of SB on health outcomes, it is important that multiple characteristics of SB can be assessed. Because of the ease of use and low burden, questionnaires often are used to recall detailed information about SB.
Therefore, the objectives of our new study were to examine and compare the content of the questionnaires measuring SB based on a well-defined and standardized classification of SB.
What did we do?
To identify as much SB questionnaires as possible three databases we searched for articles that report the development and/or the psychometric properties of self-report questionnaires to assess SB. The literature search produced a total of 1369 hits. When selecting articles based on the inclusion criteria, 82 studies were retrieved and three additional articles were identified based on hand-searching of existing reviews for a total of 60 questionnaires.
The content comparison aimed to identify the SB characteristics measured by each questionnaire for each item. To allow the comparison and analysis of the questionnaires, the decision was made to link the SB characteristics measured to the taxonomy of SB . The taxonomy served as a reference framework to identify and classify the different categories of SB (see full article).
What did we find?
Overall, our review reports wide differences in the questionnaires’ content. Questionnaires ranged from 1-115 items with the most comprehensive questionnaires measuring up to 27 SB characteristics while the least comprehensive questionnaires measured only one characteristic, overall sitting time.
All the questionnaires except two assessed time spent in SB with 17 assessing frequency and 6 assessing breaks in SB. As we were expecting, most of the questionnaires measured sitting time spent watching TV or using a computer during a day. Facets for time, posture, purpose, and type were measured most often and facets for environment, social context, status and associated behaviours were measured least often.
What did this article add?
Considerable variability was observed in the comprehensiveness of SB in the questionnaires reviewed. When selecting a SB questionnaire, one should consider the measurement properties, the characteristics of SB, and the nature of information about the frequency, duration, interruptions, and recall frame. The taxonomy-based content analysis provides a useful tool to identify and compare the content of SB questionnaires as it provides a framework of SB characteristics with which to evaluate questionnaires. This review provides support for the development of questionnaires that measure SB characteristics not currently measured in existing questionnaires.
