Adults’ Past-Day Recall of Sedentary Time

Abstract

The PAST questionnaire provided an easy-to-administer measure of sedentary time in this sample. Validity and reliability findings compare favorably with other sedentary time questionnaires. Past-day recall of sedentary time shows promise for use in future health behavior, epidemiological, and population surveillance studies.

Responsiveness of motion sensors to detect change in sedentary and physical activity behaviour

“…3233 Despite various statistical methodologies, populations and intervention designs, the SRMs are comparable to other studies that evaluated objective sedentary and PA monitoring devices. 173637 The AP has previously been shown to be sensitive to changes in SB in overweight inactive office workers over a 6 h period; however, during 6-month intervention to reduce dietary intake, reduce SB and increase PA in breast cancer survivors, the reported responsiveness index 38 (RI) was lower than in the current study (RI=0.13). 1737 The AG was able to detect change in SB (SB<100 cpm) in older adults between two 6-day monitoring periods (responsiveness statistic=0.39) 3639 but was not sensitive to change in SB (SB<50, 100, 150, 200, 250 cpm; low-frequency filter applied) in overweight inactive office workers between two 6 h periods.…”

Older adults’ reporting of specific sedentary behaviors: validity and reliability

“…First, it might actually be difficult for older adults to recall and accurately estimate the duration of specific sedentary behaviors. Questionnaires assessing sedentary behavior(s) performed during the past day might offer a solution to this issue [39], however, these might be less accurate in capturing usual engagement in sedentary behavior(s). Secondly, our test and retest assessment of the specific sedentary behaviors did not target the same seven days.…”

Reliability and Validity of a Domain-Specific Last 7-d Sedentary Time Questionnaire

“…Questionnaires therefore benefit from a short, recent recall frame, such as the last 7 d, which allows for recollection of specific rather than usual behaviors (27). A last 7-d recall frame also captures more intraindividual variability in sedentary behavior than recall frames that are even shorter, such as the past day (11). Only one questionnaire has so far incorporated sedentary time patterns (10), which have been shown to have independent health associations (20).…”

“…To date, sedentary behavior questionnaires have mostly been validated in specific populations (e.g., overweight adults (22,31), breast cancer patients (11), and middle-age women (25)), which limit generalizability of their psychometric properties to general adult populations. Furthermore, questionnaires have been compared predominantly with a waist- or hip-mounted accelerometer (6,7,10,12,15,25,31), which have important limitations.…”

“…Thigh-worn monitors that measure thigh acceleration and position with respect to gravity have been shown to accurately measure posture-based sitting time (17,21,23,32). This method has, however, rarely been used as criterion when validating sedentary behavior questionnaires (11,22). Finally, domain-specific criterion measures, derived from simultaneously collected objective monitor and log data, are also underused.…”
