Brief Summary

This study will explore the effectiveness of two different interventions, a Health Action Process Approach (HAPA) mobile health (mHealth) intervention and a Just In-Time Adaptive Intervention (JITAI), on reducing sedentary behaviour in office workers. One third of participants will receive the mHealth HAPA intervention, consisting of a theory-driven behavioural counselling session with personalized daily SMS text messages, and another third of participants will receive the JITAI intervention, a behaviour tracking mobile phone application that will alert participants once a set sedentary behaviour condition has been met. The last third of participants will act as a control where they will not receive an intervention or any further information from the letter of information. The study will take place over four weeks, with the first acting as a baseline and the intervention period filling the latter three weeks.

mHealth HAPA Intervention Group

EXPERIMENTAL

This intervention group will receive a single one-on-one online behavioural counselling session and daily personalized SMS text message boosters with the aim of increasing the breaking of consecutive work related sedentary behaviour. Counselling strategies will be grounded in the HAPA model, specifically focusing on the creation of an action plan and the development of coping strategies to increase sedentary behaviour breaks. The SMS text message boosters will be personalized based on participant's preferences of timing, type, frequency, and length. The boosters will framed through HAPA principles with content focusing on risk awareness, outcome expectancy, action and coping planning, barriers and resources, and self-efficacy. The intervention will last for three weeks.

Behavioral: HAPA behavioural counselling + SMS text message boosters

JITAI Group

EXPERIMENTAL

This intervention group will receive push notifications from a EMA behaviour monitoring mobile application that will be downloaded to each participants' mobile phones. The application will measure and monitor a participant's sedentary behaviour and once a pre-set condition of 30 consecutive sedentary minutes has been reached, the application will administer a push notification notifying the participant to break their sedentary behaviour. The push notifications will ask the participants to stand up, stretch, or lightly walk around to break their current behaviour. The intervention will last for three weeks.

Device: JITAI

Control Group

NO INTERVENTION

The control group will receive no intervention or further instruction past the letter of information.

Interventions

HAPA behavioural counselling + SMS text message boosters BEHAVIORAL

Behavioural counseling grounded in the Health Action Process Approach (HAPA; i.e., action planning and coping planning) paired with daily personalized HAPA guided SMS text message boosters to reduce consecutive workplace sedentary behaviour.

mHealth HAPA Intervention Group

JITAI DEVICE

EMA monitoring mobile phone application that uses a phone's on-board accelerometer to monitor a participant's sedentary behaviour and deliver a push notification once a set condition has been met. This intervention will be utilized to reduce consecutive workplace sedentary behaviour.
