简要总结
In COVID-19 times, there has been a large increase in number of people working from home; with limited places to go, an abrupt change to people's lives and lack of knowledge about the dangers of sedentary behaviour (SB), it is important to help workers develop and effortlessly incorporate healthy movement routines to optimize daily productivity and health. The combined lack of knowledge on literature on SB profiles of full time, home-based workers, effects of framing of SB reduction strategies, and strategy preference uncertainty makes for a novel study. This will be a 4-week intervention that looks at whether telling a full time, home-based office worker to do pre-selected strategies using different framing structures to break up their sedentary behaviour (SB) (i.e. sitting) will change their SB profiles. Investigators are looking to see whether having the choice (or not) to choose strategies in an unfamiliar health related selection (preference uncertainty) will create greater changes in SBs. As well, the researchers are incorporating behavioural economics' by altering choice structure in relation to behaviour change and program engagement. Workers' work-related SB will be measured by a device at baseline and on the last week of the intervention. Workers will be provided with an SB educational video to increase knowledge and motivation for change. Any SB changes in relation to productivity, mental wellness, behaviour intentions etc. will also be measured.
详细描述
Regardless of group assignment, participants will receive the same three-minute educational video at the beginning (week 1) and halfway through (week 3) the intervention. Each group will also receive two weekly sedentary behaviour reduction strategies that align with the concept of "moving more often".
Participants will be initially randomized into the no choice strategy assignment or choice of strategy assignment groups, then immediately randomized into one of three choice structure conditions. The strategy assignment groups (no choice and choice) will receive two individually randomized (out of the ten "move more" strategies (see Table 2) each week. The two assigned strategies will be randomized to the participant each week; therefore, strategies may or may not change week to week. When presented with the two strategies, the Qualtrics program will state: "These will be your two move more strategies (click next to acknowledge you have seen your strategies)", followed by two multiple choice styled strategies. Regardless of if the person decides to click the boxes beside the strategies or clicks "next", the strategies will be inserted into the one of the three choice structure statements. Those randomized into the "choice of strategy assignment" group will be asked in their baseline questionnaire whether or not they: "prefer to choose and manage their own sitting reduction strategies from a list of expert recommended strategies OR prefer to be assigned with two strategies every week from a list of expert recommended strategies". Those opting to be assigned strategies ("Choice Strategy Assignment" group) will be assigned two random strategies, just like the "No Choice Strategy Assignment" group; however, they remain different from the "No Choice Strategy Assignment" group because they were given and chose the option to be given strategies. Those selecting to choose and manage their own strategies "Choice Strategy Self-Selection" group will be presented the same ten strategies each week, in random order, and will have the option to choose two strategies. The strategies can remain the same or change from week to week.
As mentioned, participants will be randomly assigned to one of three choice structure conditions: opt-in, Active Choice or Enhanced Active Choice. All three messages will contain the following introduction: "As you now know, breaking up your sitting every 45 minutes with 2-3 minutes of light activity can significantly reduce negative health risks associated with prolonged sitting." This message will end with one of the three choice structures.
In the opt-in condition they will be asked to "Place a check in the box [agree] if you will breakup your sitting throughout your work hours by [strategy] this week". The strategy statement is followed up by; OR, click the next button at the bottom." Within the opt-in condition, the default is to not participate (by clicking "next"); participants are not required to explicitly state they do not want to do the strategy.
In the Active choice condition, participants will be required to either, "Place a check in one box: I will break up my sitting throughout my work hours by [strategy] this week or, I will not break up my sitting throughout my work hours by [strategy] this week".

研究组 & 干预措施
Assigned Strategies: Opt-in
Participants in this group will be assigned two behavioural strategies under the theme of "moving more" and will be asked to "Place a check in the box [agree] if you will breakup your sitting throughout your work hours by X this week". The strategy statement is followed up by; OR, click the next button at the bottom." Within the opt-in condition, the default is to not participate (by clicking "next"): participants are not required to explicitly state they do not want to do the strategy
干预措施: Assigned Strategies: Opt-in (Behavioral)
Assigned Strategies; Active Choice
Participants in this group will be assigned two behavioural strategies under the theme of "moving more". In the Active choice condition, participants will be required to either, "Place a check in one box: I will break up my sitting throughout my work hours by [strategy] this week or, I will not break up my sitting throughout my work hours by [strategy] this week".
干预措施: Assigned Strategies: Active Choice (Behavioral)
Assigned Strategies; Enhanced Active Choice
Participants in this group will be assigned two behavioural strategies under the theme of "moving more". In the Enhanced Active Choice condition, participants will to required to choose between two alternatives: "I will break up my sitting throughout my work hours this week by [strategy] to reduce my risk of diabetes, mental health issues and other detrimental health outcomes and I want to win the eGiftcard or, I will not break up my sitting time during my work hours by [strategy] this week even if it means I increase my risk of developing diabetes, mental health issues and other detrimental health outcomes and I don't care about winning an eGiftcard"
干预措施: Assigned Strategies: Enhanced Active Choice (Behavioral)
Choice of Assignment; Opt-in
Those opting to be assigned strategies ("Choice Strategy Assignment" group) will be assigned two random strategies, just like the "No Choice Strategy Assignment" group; however, they remain different from the "No Choice Strategy Assignment" group because they were given and chose the option to be given strategies. Those selecting to choose and manage their own strategies "Choice Strategy Self-Selection" group will be presented the same ten strategies each week, in random order, and will have the option to choose two strategies. The strategies can remain the same or change from week to week.
