Effect of the WAIO Digital Platform on Multidimensional Wellbeing in Adults in Argentina

Efecto sistémico de la Inteligencia Artificial en el Bienestar Integral en Argentina: un Modelo Multidimensional y Culturalmente Adaptado Basado en SAMHSA

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.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	Baseline and 6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in WAIO Integral Wellbeing Standardized Score From Baseline to 3 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.	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.	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.	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.	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.	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.	From baseline through 6 months

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Internal Consistency of the WAIO Integral Wellbeing Inventory	The scale used is the Wellbeing All-In-One (WAIO) Integral Wellbeing Inventory. Its standardized wellbeing scores range from 0 to 100, with higher scores indicating higher wellbeing. Internal consistency of the preliminary WAIO Integral Wellbeing Inventory and its dimension-specific subscales will be evaluated using Cronbach's alpha and McDonald's omega during the psychometric calibration phase. A Cronbach's alpha of 0.70 or higher is prespecified as the threshold for acceptable internal consistency of each subscale.	Baseline
Factorial Structure of the WAIO Integral Wellbeing Inventory	The scale used is the Wellbeing All-In-One (WAIO) Integral Wellbeing Inventory. Standardized wellbeing scores derived from the inventory range from 0 to 100, with higher scores indicating higher wellbeing. The factorial structure of the preliminary 40-item WAIO Integral Wellbeing Inventory will be evaluated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to assess support for the hypothesized eight-dimensional wellbeing structure based on the SAMHSA framework.	Baseline
Convergent Validity of the WAIO Integral Wellbeing Inventory	The scale used is the Wellbeing All-In-One (WAIO) Integral Wellbeing Inventory. Its standardized wellbeing score ranges from 0 to 100, with higher scores indicating higher wellbeing. Convergent validity will be evaluated by examining correlations between WAIO Integral Wellbeing Inventory scores and standardized measures assessing related constructs during the psychometric calibration phase. The outcome of this analysis will be the strength and direction of the correlations between these measures.	Baseline
Test-Retest Reliability of the WAIO Integral Wellbeing Inventory	The scale used is the Wellbeing All-In-One (WAIO) Integral Wellbeing Inventory. Its standardized wellbeing score ranges from 0 to 100, with higher scores indicating higher wellbeing. Temporal stability of the WAIO Integral Wellbeing Inventory will be assessed in a randomly selected 10% subsample of participants from the psychometric calibration phase (approximately 20 participants). The inventory will be administered again 14 days after the baseline assessment, during an intervention-free interval. Test-retest reliability will be evaluated using the intraclass correlation coefficient (ICC), with higher ICC values indicating greater temporal stability. An ICC greater than 0.75 is prespecified as the threshold for acceptable temporal stability.	Baseline and 14 days
