Overview

This study will evaluate the effect of an artificial intelligence-supported digital wellbeing platform, Wellbeing All-In-One (WAIO), on multidimensional wellbeing in adults living in Argentina. The study includes an initial phase to evaluate and refine a culturally adapted wellbeing questionnaire based on the eight dimensions of the SAMHSA wellness framework. It will then conduct a randomized controlled trial in which participants are assigned to either immediate access to the WAIO platform or an active waitlist control group. Participants will be followed for six months. The study will examine changes in self-reported wellbeing across physical, emotional, social, occupational, spiritual, financial, intellectual, and environmental dimensions, as well as engagement, retention, and safety.

This study uses a sequential mixed-method design consisting of an instrumental calibration phase followed by a two-arm, parallel randomized controlled trial. During the initial instrumental phase, the preliminary 40-item WAIO Integral Wellbeing Inventory, culturally adapted from the SAMHSA eight-dimension wellness framework, will undergo psychometric evaluation. The first approximately 200 participants completing the baseline assessment will contribute to this phase. The planned evaluation includes assessment of internal consistency, factorial structure, convergent validity, comprehensibility, and test-retest reliability. Items retained after this prespecified calibration process will be used for subsequent longitudinal assessments. The experimental phase will evaluate a digital wellbeing intervention delivered through the Wellbeing All-In-One (WAIO) progressive web application. WAIO integrates more than 30 interconnected digital tools organized around eight dimensions of wellbeing: physical, emotional, social, occupational, spiritual, financial, intellectual, and environmental. Artificial intelligence is used to personalize aspects of the user experience. A total recruitment target of 2,000 adults in Argentina is planned. Participants entering the randomized phase will be allocated to one of two parallel groups. Participants in the immediate-intervention group will receive access to WAIO and weekly engagement messages. Participants in the active waitlist control group will receive general health information monthly and will not receive access to WAIO during the six-month comparison period. Access to WAIO will be provided to the waitlist group after completion of that period. Participants will be assessed at baseline and followed longitudinally over six months. The study is designed to evaluate the trajectory of multidimensional wellbeing, the relationship between exposure to the digital intervention and changes in wellbeing, participant retention, and intervention safety. The study includes prespecified safety procedures for the identification and management of potentially serious risk signals detected during use of the digital platform.

Interventions

WAIO Multidimensional Digital Wellbeing InterventionBEHAVIORAL

A digital wellbeing intervention delivered through the Wellbeing All-In-One (WAIO) progressive web application. The platform integrates more than 30 interconnected digital tools organized across eight dimensions of wellbeing: physical, emotional, social, occupational, spiritual, financial, intellectual, and environmental. Artificial intelligence is used to personalize aspects of the user experience. Participants assigned to the immediate-intervention arm receive access to the platform during the 6-month comparison period and one weekly WhatsApp message encouraging engagement.

General Health Information MessagesBEHAVIORAL

Participants assigned to the active waitlist control arm receive one general health information message per month through WhatsApp during the 6-month comparison period. They do not receive access to the WAIO platform during this period. Access to WAIO is offered after completion of the 6-month comparison period, beginning in month 7.

Outcomes

Primary Outcomes

Change in WAIO Integral Wellbeing Standardized Score From Baseline to 6 Months

The WAIO Integral Wellbeing Inventory assesses self-reported wellbeing across eight dimensions based on the SAMHSA wellness framework: physical, emotional, social, occupational, spiritual, financial, intellectual, and environmental wellbeing. A standardized overall score ranging from 0 to 100 will be calculated, with higher scores indicating higher integral wellbeing. Longitudinal scoring will use the items retained after the prespecified psychometric calibration phase.

Time frame: Baseline and 6 months

Secondary Outcomes

Change in WAIO Integral Wellbeing Standardized Score From Baseline to 3 Months

Time frame: Baseline and 3 months

Change in the Eight Dimension-Specific WAIO Wellbeing Scores

Dimension-specific wellbeing scores will be calculated for the eight domains assessed by the WAIO Integral Wellbeing Inventory: physical, emotional, social, occupational, spiritual, financial, intellectual, and environmental wellbeing. Each dimension-specific score will be standardized on a 0-to-100 scale, with higher scores indicating higher wellbeing in that dimension. Scores will be derived from the items retained after the prespecified psychometric calibration phase. Changes over time will be evaluated separately for each wellbeing dimension.

Time frame: Baseline, 3 months, and 6 months

Change in Self-Rated General Health

Self-rated general health will be assessed using a single-item measure asking participants to rate their health in general. Response categories are Excellent, Very Good, Good, Fair, and Poor. Changes in the distribution of self-rated health responses will be evaluated over the follow-up period.

Time frame: Baseline, 3 months, and 6 months

Participant Retention Rate at 3 and 6 Months

Percentage of randomized participants who remain in the study at each scheduled follow-up time point. Retention will be assessed at T1 (3 months) and T2 (6 months) using study and platform records.

Time frame: 3 months and 6 months

Incidence of Adverse Events and Serious Adverse Events

The number and proportion of participants experiencing one or more adverse events or serious adverse events during the 6-month follow-up period will be assessed. Safety events will be identified through the study's SOS reporting mechanism and active safety monitoring procedures.

Time frame: From baseline through 6 months

Correlation Between WAIO Exposure and Change in Multidimensional Wellbeing

Among participants assigned to the immediate WAIO intervention arm, exposure to the digital intervention will be quantified using backend logs, including total time of use, frequency of accesses, and completion rate. Correlation analyses will assess the relationship between these exposure indicators and the magnitude of change in overall and dimension-specific wellbeing scores from baseline to 6 months.
