Well-being Impact Assessment

• WIA is a multidimensional methodology that defines well-being using both objective indicators and subjective measures like life satisfaction and autonomy.
• It employs advanced statistical models, Bayesian techniques, and iterative stakeholder engagement to capture complex interdependencies.
• WIA is applied across domains such as AI ethics, digital health, and policy reform to drive data-informed decisions that enhance overall human flourishing.

Well-being Impact Assessment (WIA) is a rigorous, multidimensional methodology designed to measure, evaluate, and inform decisions about the effects of policies, technologies, and interventions on the well-being of individuals and communities. Unlike traditional impact assessments that focus solely on economic or technical metrics, WIA integrates objective and subjective indicators, incorporates stakeholder engagement, and often features iterative, context-sensitive evaluation frameworks. WIA is increasingly central in fields ranging from social policy and artificial intelligence to user interface design and workplace innovation, reflecting a broad consensus that complex interventions require thorough consideration of their multifaceted effects on human flourishing.

1. Core Concepts and Theoretical Foundations

WIA frameworks are grounded in the recognition that well-being is an inherently multidimensional construct. Foundational literature distinguishes between objective conditions (such as income, employment, public services, and environmental quality) and subjective states (such as self-reported life satisfaction, happiness, and perceived autonomy) (Pereira et al., 30 Jan 2024). Advanced models further differentiate between hedonic factors (momentary pleasure, affect) and eudaimonic dimensions (meaning, self-acceptance, autonomy, and personal growth) (Maden et al., 2023). This theoretical architecture is reflected in policy evaluation methodologies that aggregate both objective and subjective indicators to capture the full scope of human well-being.

Several frameworks have emerged to formalize WIA:

• IEEE Std 7010-2020 operationalizes well-being as a set of twelve domains (including affect, community, culture, environment, and more), specifying validated indicators for each area (Schiff et al., 2020).
• WE Pluralism methodology consolidates individual and group-level well-being over gradations ranging from personal subjectivity to intersubjective "narrow-wide WE" (family, community, up to the global level). Well-being is captured as the sum or weighted aggregate of narrow and wide group functions:

$W(x) = r \cdot W_n(x_n) + (1 - r) \cdot W_w(x_w)$

where $W_n$, $W_w$ are well-being functions for the narrow and wide group scales, respectively, and $r$ is a normalization factor (Kato, 2023).

These frameworks emphasize the need to balance qualitative judgments, quantitative metrics, and structural relationships among well-being components.

2. Methodological Approaches

WIA methodologies span advanced statistical modeling, qualitative participatory techniques, and hybrid processes that integrate multiple data streams:

• Multivariate and Copula-Based Models: Well-being is often modeled using joint copula-based multivariate panel ordinal models, particularly suited for capturing both the marginal distributions of multiple satisfaction indicators (e.g., health, income, family) and their temporal and cross-sectional dependencies (Nikoloulopoulos et al., 2016). The generic form for a $d$-dimensional outcome is:

$$h(y; \theta, R) = \int_{a_1}^{b_1} \cdots \int_{a_d}^{b_d} t_d(z_1, ..., z_d; R) dz_1 \cdots dz_d$$

Estimation is achieved via maximum simulated likelihood using randomized quasi Monte Carlo methods.

• Bayesian Hierarchical Models and Interrupted Time Series (ITS): To evaluate policy change impacts on mental well-being, Bayesian ITS models are constructed. A typical specification uses a Bernoulli likelihood for binary well-being outcomes (e.g., distress/no-distress), adjusting for spatio-temporal dependencies and covariates. The standardized impact is often reported as:

$$\rho = \frac{p_{EA} - \tilde{p}_{EB}}{\tilde{p}_{EB}}$$

where $p_{EA}$ is the prevalence for the exposed after intervention, and $\tilde{p}_{EB}$ is the control-adjusted prevalence before (Gascoigne et al., 2023).

• Iterative and Stakeholder-Centered Processes: WIA is fundamentally iterative. Frameworks like IEEE 7010 and "Enhanced Well-being Impact Assessment" (EWIA) emphasize full life-cycle assessment with both ex-ante and ex-post phases (Schiff et al., 2020, Havrda et al., 2020). Steps include stakeholder engagement, dashboard metric selection, data collection, analysis, regular reassessment, and policy adjustment.
• Participatory and Tangible Data Collection: Non-traditional approaches—such as the Communal Loom—combine tangible, embodied data collection (e.g., survey-to-artifact mapping in a therapeutic setting) with structured, machine-readable output. This yields both quantitative data and qualitative, expressive artifacts that encode group well-being states (Parikh et al., 31 Oct 2024).

3. Domains of Application

WIA has been adapted to diverse domains, each with domain-specific implementation nuances:

• Artificial Intelligence and Autonomous Systems: WIA for AI centers human flourishing over the system lifecycle. IEEE 7010 and EWIA frameworks demand systematic stakeholder engagement and the integration of multi-domain indicators (affect, community, sustainability, etc.). Algorithmic impact, fairness, and trade-off navigation (privacy vs. safety, for example) are formalized in dashboard metrics (Schiff et al., 2020, Havrda et al., 2020).
• Digital Healthcare and Mental Well-Being: Intelligent systems—from conversational agents to robotic companions—are evaluated along criteria such as transparency, explainability, privacy, error management, empathy, and healthcare provision. Assessment blends instrumented behavioral data with subjective user outcomes (Jovanovic et al., 2021).
• Workplace and Organizational Context: Passive sensing technologies in workplaces are subjected to WIAs that consider cascading impacts (cultural, interpersonal, individual), ambiguity in "well-being" definitions, and the necessity of early, iterative stakeholder involvement (Kawakami et al., 2023).
• Policy and Welfare Reform: Policy evaluation (e.g., welfare reform impacts on mental well-being) exploits spatio-temporal statistical models and focuses on heterogeneity across population strata, tying quantitative prevalence changes to contextual mediators such as economic status or geographic deprivation (Gascoigne et al., 2023).
• Product Design and Inclusive Engineering: WIA frameworks account for dignity, empowerment, and inclusivity, using explicit formulas such as

$DWB = N_{GF} \times R_P \times N_F$

where $N_{GF}$ is the number of group functions, $R_P$ is resources provided, and $N_F$ is number of needs fulfilled (Yaldiz et al., 24 Dec 2024).

4. Metrics, Models, and Formulas

WIA employs a diverse set of metrics and mathematical frameworks, selected for their suitability to the application context:

Domain	Example Metric/Formulation	Reference
AI Systems	$W = \sum_{i=1}^n \alpha_i \cdot I_i$ (weighted sum across domains)	(Schiff et al., 2020)
Policy Evaluation	$W = r \cdot W_n(x_n) + (1-r)\cdot W_w(x_w)$ (WE pluralism)	(Kato, 2023)
Product Lifecycle	$DWB = N_{GF} \times R_P \times N_F$	(Yaldiz et al., 24 Dec 2024)
Longitudinal Data	$$\rho = \frac{p_{EA}-\tilde{p}_{EB}}{\tilde{p}_{EB}}$$ (standardized impact change)	(Gascoigne et al., 2023)
User Assessment	Mixed indices: mood, engagement, self-regulation, etc.	(Montes et al., 23 Apr 2025, Campos, 2018)

These formulations support both index construction (for dashboards or aggregate reporting) and robust inferential modeling.

5. Challenges, Trade-offs, and Limitations

Key challenges documented in the literature include:

• Measurement Uncertainty and Subjectivity: Well-being is context-sensitive and often resists reduction to single indices. Aggregation choices (weighting, domain selection) can reflect or obscure stakeholder priorities (Pereira et al., 30 Jan 2024, Kato, 2023).
• Attribution and Causality: Establishing causal links between interventions (especially sociotechnical or policy changes) and observed shifts in well-being is complex in non-experimental or high-confounder contexts (Schiff et al., 2020, Gascoigne et al., 2023).
• Computational Demands: High-dimensional estimation—especially with copula-based or Bayesian time-series models—demands significant computational resources and careful algorithmic tuning (Nikoloulopoulos et al., 2016).
• Stakeholder Engagement and Consensus: Success depends on representing the priorities and perceptions of diverse groups in both subjective and objective measures. Approaches such as joint fact-finding and the integration of “narrow-wide WE” consensus address this (Kato, 2023).
• Iterative Adaptation: WIA frameworks must be dynamic, with regular updating of metrics and indicators to reflect emerging impacts, new data, or changing social values (Havrda et al., 2020).

6. Practical Implementation and Future Directions

Recent studies highlight practical routes for WIA implementation and areas of ongoing research:

• Integration with Product and Policy Lifecycles: WIA can be formally embedded in Plan-Do-Check-Act (PDCA) cycles, agile development sprints, or policy monitoring structures, leveraging indicator dashboards that support periodic reassessment (Schiff et al., 2020).
• Participatory and Tangible Assessment: Combining participatory qualitative data with tangible artifact generation (as in the Communal Loom) facilitates holistic, community-centered data collection and increases assessment legitimacy (Parikh et al., 31 Oct 2024).
• Personalized and Adaptive Systems: Machine learning models are being applied to predict and personalize interventions (e.g., optimal policy choice in AV interactions based on predicted change in well-being), moving towards real-time, context-aware impact optimization (Mehrotra et al., 2023).
• Blended Quantitative–Qualitative Methods: Mixed-methods designs, combining psychometric scales and focus groups, expose the limitations of relying on a single mode of assessment and capture nuanced, context-dependent effects (Montes et al., 23 Apr 2025).
• Socioaffective and Power User Considerations: Automated affective classifiers and monitoring for power-user subpopulations are central in evaluating digital interventions (e.g., voice chatbots) for risks of dependence or undesired psychosocial impacts (Phang et al., 4 Apr 2025).

Areas for further research include enhancing attribution methodologies, refining metric aggregation, addressing privacy in data-rich environments, and increasing the scalability and responsiveness of participatory WIA systems.

7. Significance and Policy Implications

WIA is increasingly recognized as essential for ethical, effective intervention and technology design:

• Provides multidimensional, empirically grounded evaluation tools to policymakers, designers, and engineers.
• Helps to identify subtle indirect effects, persistent or delayed impacts, and complex interdependencies that traditional evaluation approaches may miss.
• Ensures that subjective experiences and community values inform the interpretation and application of high-dimensional quantitative data.
• Fosters transparency, accountability, and iterative improvement by systematizing feedback loops and stakeholder participation.
• Supports the design of human-aware policies, services, and products that prioritize long-term flourishing over narrow technical or economic criteria.

Collectively, WIA represents a methodologically rich arena requiring advanced statistical, participatory, and computational techniques to generate actionable, societally aligned insights into the effects of complex interventions on well-being.
