Brief Summary

Societal changes have resulted in reduced demands to be active and increased daily time spent sitting. Sedentary behavior (SB) has been linked to many health problems such as type 2 diabetes and heart disease. Office-working adults are a high-risk population for excessive SB. Increasing the length and frequency of breaks from sitting and increasing the time spent standing and engaged in light physical activity are ways to decrease SB. The purpose of this study is to determine whether combining a Health Action Process Approach-based (theory-driven), specifically action and coping planning intervention, with a tailored text messaging intervention can reduce workplace sitting time among adult office workers. Participants in the intervention group will receive one behavioural counselling session, followed by daily, tailored text messages over a 6-week period, with a focus on encouraging them to reduce their occupational sitting time by increasing their frequency and duration of breaks from sitting, as well as time spent standing and engaged in light-intensity physical activity. It is expected that office-working adults who receive the planning intervention and tailored text messages will report greater increases in non-sedentary behaviours (e.g., break frequency, break duration, standing, light physical activity) than those who do not receive the intervention.

Study Arms (2)

HAPA-treatment

EXPERIMENTAL

(SB-related planning + daily text messages)

Behavioral: (SB-related planning + daily text messages)

Control

NO INTERVENTION

(No Treatment) 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 questionnaires.

Interventions

Participants will receive a one-on-one behavioral counseling session, and planning sheet as reference for developing strategies as part of their Action/Coping Plan. Participants will be asked to form 3-4 actions/coping plans specifying when, where, how, and for how long they would reduce workplace sitting time; and anticipate potential barriers and identify ways they could be overcome. Strategies will focus on increasing break frequency to every 30-45 minutes, achieving a break duration of 2-3 minutes, and increasing standing and light-intensity PA time, during work hours. Participants will receive sedentary behaviour-related text messages twice daily, depending on their preferences and schedule, which will act as mini-booster interventions.

Model Details: This study will employ a prospective, 2-group, repeated measure (2x5), randomized controlled trial design. All participants will be randomized into either a 6-week HAPA-treatment (SB-related planning + text messages intervention) or waitlisted control (no treatment) condition. All primary outcomes will be assessed at four time points (baseline, 2, 4, and 6 weeks), and again at a two-week follow-up (8 weeks). Action and coping planning and action control towards reducing workplace sitting time will be assessed at the same time points. Secondary outcome assessments (i.e., work- and health-related outcomes) will occur pre- (baseline) and post-intervention (6 weeks).
