TIDieR^a,b checklist item		Description
What?		The health care professionals (HCPs) received training in setting SMART^c goals and digital coaching. Patients receive 1 or 2 personal meetings (face-to-face or digital) with the HCP, followed by asynchronous Web-based consultations based on dialog by means of short message service text message or video. The consultations addressed the patient’s registrations, goal setting, and questions regarding diet, exercise, and lifestyle plan and took chronic diseases into consideration. The LIVA app is set up with short explanations on different functions and notifications and reminders to the patients to register and give feedback on the health coaching. The sessions provide the user with information in relation to their status, specific focus on goals, and recommendations on how to improve their behaviors.
eHealth coaching sessions		Included BCT^d from CALO-RE^e taxonomy (hereafter referred to as BCT): provide information on consequences of the behavior in general and to the individual, goal setting: behavior and outcome, action planning, barrier identification or problem solving, set graded tasks, prompt review of behavioral goals, prompt review of outcome goals, prompt rewards contingent on effort or progress toward behavior, prompting generalization of a target behavior, and provide feedback on performance.
Goals and inputs		The goals and inputs described underneath are available to the patient, who can choose his or her focus area, set specific concrete goals, and keep record of specified behaviors by reporting on them on a daily, weekly, or monthly basis. This allows the user and the HCP to follow progress or setbacks as the numbers and registrations get visualized with graphs and curves. All advices from the HCP follow national guidelines from the Danish National Board of Health.
	Dietary goals and plans		Dietary goals and plans can be set at many different levels from simple changes aiming at changing 1 meal a day to more complex changes aiming at a completely new diet composition to remedy digestion problems.
	Physical activity goals and plans		Goal setting and recording of type and time for executing any given physical activity. The user receives advice and/or video on activities in a variety of contexts to foster physical activity as a more integrated part of the person’s life (BCT: provide instruction on how to perform the behavior, prompting generalization of a target behavior, and relapse prevention or coping planning).
	Life goals		Goals on a healthy, joyful life as the patient sees it, for example, daily life with less stress, stronger social bonds with friends and family, and coping skills for diseases.
	Weight-input		Set current weight and goal for a lower or higher weight and register new measurements on a daily, weekly, or monthly basis.
	Steps-input		When downloading the app, the user can accept that their information on steps recorded on a smartphone are imported directly, and tailored messages on progress toward a set goal appear simultaneously (BCT: teach to use prompts or cues).
	Pain, sleep, and mood-input		Give daily feedback on pain, sleep, and mood, which can affect the ability to perform a given behavior (BCT: relapse prevention or coping planning).
	Smoking-input		Set goals to bring down the number of cigarettes smoked on a daily basis, leading to cessation.
	Blood glucose, cholesterol, and lung capacity-input		Keeping a record of specified measures expected to be influenced by the different behavior changes addressed. In LIVA, this includes blood glucose, cholesterol, and lung capacity. (BCT: prompt self-monitoring of behavioral outcome and provide information on consequences of the behavior in general and to the individual).
Forum		Online forum where the users can exchange knowledge, gain social support, and build new relationships; the health coach can add advices to the forum users (BCT: plan social support or social change).
Who provided?		Health professionals with basic training as nurses, physiotherapist, dieticians, and occupational therapists were performing the health coaching.
How?		Individually delivered via the app or Web.
Where?		Initial personal meeting in the health centers or digital. Then solely Web-based delivery.
When and how much?		The initial consultations with a health coach is estimated to last approximately 45 to 60 min. The following asynchronous eHealth coaching sessions were carried out once weekly in the first 3 months and then for maintenance every third week for the last 9 months. Hereafter, the patient can receive 2 eHealth coaching sessions and use LIVA as a personal behavioral change tool. (BCT: use of follow up prompts).
Tailoring		Every patient received personal eHealth coaching sessions from their designated health coach. The feedback given was based on the patient’s inputs on LIVA.
