Brief Summary:
Societal changes have resulted in reduced demands to be active and increased daily time spent sitting. Excessive sitting has been shown to be a health hazard. The purpose of this study is to examine whether sedentary behaviour and diabetes information grounded in The Action Process Approach is a meaningful source of motivation to reduce daily sitting time among adult office workers. The intervention will target risk perceptions related to sitting by presenting research on prolonged sitting and diabetes risk, the effectiveness of breaking up prolonged sitting, and provide strategies to break up sitting. It is expected that participants who receive this information will report greater motivation and intentions to reduce both work and leisure sitting time.

Arm Intervention/treatment
Experimental: Experimental Group (HAPA SB)

Experimental (same outcome questionnaire but with informational slideshow focusing on sedentary behaviour and diabetes risk)

HAPA SB Intervention Slideshow

Behavioral: HAPA SB Intervention Slideshow
In the experimental condition, participants will receive sedentary behaviour and diabetes information in the form of a slide show that will be viewed online. The intervention aims to address all components of the Health Action Process Approach. For the experimental group, the intervention material will target risk perceptions (RP) related to sitting by presenting evidence supported by research on sedentary behaviour and diabetes risk; outcome expectancies (OE) by presenting research on the effectiveness of breaking up sedentary time for improving blood sugar and insulin levels; and self-efficacy (SE) by providing strategies on how to reduce and break up sitting time.

Active Comparator: Attention-Control Group (HAPA MVPA)

Attention-Control (same outcome questionnaire but with slideshow focusing on benefits of moderate-vigorous physical activity)

HAPA MVPA Intervention Slideshow

Behavioral: HAPA MVPA Attention-Control Slideshow
In the attention-control, participants will receive information in the form of a slide show that will be viewed online. The intervention aims to address all components of the Health Action Process Approach. The attention-control slide show will take the same approach as the Experimental group slideshow but the slides will be geared towards meeting moderate-vigorous physical activity guidelines.

No Intervention: Control Group

Control (outcome questionnaire without any slideshow)

Participants randomly assigned to the control group will receive no information or intervention of any kind and will only be asked to complete the outcome questionnaire.

  3. Participants confidence to reduce leisure sitting time [ Time Frame: Immediately Post-intervention ]
    Health Action Process Approach sedentary-derived pre-intentional motivational construct - Self-Efficacy (SEL) 55-items; 11-point scale Five Sub-scale scores; SEL1 (12-items) - Confidence to reduce sitting time outside of work; SEL2 (10-items) - Confidence to increase the number of breaks from sitting outside of work; SEL3 (9-items) - Confidence to increase the length of breaks from sitting outside of work; SEL4 (12-items) - Confidence to increase standing time outside of work; SEL5 (12-items) - Confidence to increase light movement time outside of work

  4. Participants confidence to reduce occupational sitting time [ Time Frame: Immediately Post-intervention ]
    Health Action Process Approach sedentary-derived pre-intentional motivational construct - Self-Efficacy (SEO) 55-items; 11-point scale Five Sub-scale scores; SEO1 (12-items) - Confidence to reduce sitting time at work; SEO2 (10-items) - Confidence to increase the number of breaks from sitting at work; SEO3 (9-items) - Confidence to increase the length of breaks from sitting at work; SEO4 (12-items) - Confidence to increase standing time at work; SEO5 (12-items) - Confidence to increase light movement time at work
