Brief Summary

The Libellules (WB6Dim) study aims to validate a digital self-assessment tool for measuring individual well-being across six dimensions: sleep and recovery, emotional climate, self-esteem, perceived autonomy, energy reservoir, and hyperconnection. This observational study includes approximately 800 adult participants divided into two cohorts: one group completes the self-assessment tool only, while the other group additionally performs a brief video-based relaxation exercise during the 15-day interval between evaluations. Each participant completes the Libellules questionnaire and a set of validated gold-standard psychometric scales (including PSS-10, ISI-7, CFQ, SAS-SV, and PIUQ-9) at baseline and after 15 days. The primary objective is to evaluate the convergent validity, internal consistency, and test-retest reliability of the Libellules items compared with established instruments. The study is fully anonymous, non-interventional, and conducted in compliance with data protection regulations (CNIL, GDPR).

Outcome Measures

Primary Outcomes (15)

• Internal Consistency (Cronbach's Alpha) of the WB6Dim Sleep and Recovery dimension

  Evaluation of the internal consistency (Cronbach's alpha) of the Sleep and Recovery well-being dimension assessed by the Libellules / WB6Dim digital questionnaire. Score range: From 0 to 100. Interpretation: The higher the score, the stronger your resources. Higher scores reflect better balance.

  Evaluation of the internal consistency (Cronbach's alpha) of the Emotional Climate well-being dimension assessed by the Libellules / WB6Dim digital questionnaire. Score range: From 0 to 100. Interpretation: The higher the score, the stronger your resources. Higher scores reflect better balance.

  Evaluation of the internal consistency (Cronbach's alpha) of the Self-Esteem well-being dimension assessed by the Libellules / WB6Dim digital questionnaire. Score range: From 0 to 100. Interpretation: The higher the score, the stronger your resources. Higher scores reflect better balance.

  From baseline (T0) to day 14 (T14).

• Internal Consistency (Cronbach's Alpha) of the WB6Dim Internal Tension dimension

  Evaluation of the internal consistency (Cronbach's alpha) of the Internal Tension well-being dimension assessed by the Libellules / WB6Dim digital questionnaire. Score range: From 0 to 100. Interpretation: The higher the score, the stronger the tension. Lower scores reflect better balance.

  From baseline (T0) to day 14 (T14).

  Evaluation of the internal consistency (Cronbach's alpha) of the Hyperconnection well-being dimension assessed by the Libellules / WB6Dim digital questionnaire. Score range: From 0 to 100. Interpretation: The higher the score, the stronger the hyperconnection. Lower scores reflect better balance.

  From baseline (T0) to day 14 (T14).

• Internal Consistency (Cronbach's Alpha) of the WB6Dim Cognitive Saturation dimension

  Evaluation of the internal consistency (Cronbach's alpha) of the Cognitive Saturation well-being dimension assessed by the Libellules / WB6Dim digital questionnaire. Score range: From 0 to 100. Interpretation: The higher the score, the stronger the saturation. Lower scores reflect better balance.

  From baseline (T0) to day 14 (T14).

• Test-Retest Reliability (Intraclass Correlation Coefficient) of the WB6Dim Sleep and Recovery dimension

  Evaluation of the temporal stability of the Sleep and Recovery well-being dimension assessed by the Libellules / WB6Dim digital questionnaire over a 14-day interval. Score range: Intraclass Correlation Coefficient (ICC), from 0 to 1. Interpretation: Higher ICC values indicate greater temporal stability of the score over time.

  Day 0 to Day 14

• Test-Retest Reliability (Intraclass Correlation Coefficient) of the WB6Dim Self-Esteem dimension

  Evaluation of the temporal stability of the Self-Esteem well-being dimension assessed by the Libellules / WB6Dim digital questionnaire over a 14-day interval. Score range: Intraclass Correlation Coefficient (ICC), from 0 to 1. Interpretation: Higher ICC values indicate greater temporal stability of the score over time.

Study Arms (2)

Cohort A - Standard self-assessment

Participants complete the digital self-assessment "Libellules / WB6Dim" at baseline (T0) and after 14 days (T14) without any additional intervention. This group serves as the control for test-retest reliability and internal consistency analyses.

Cohort B - Self-assessment + micro-intervention

Participants complete the same digital self-assessment "Libellules / WB6Dim" at baseline (T0) and after 14 days (T14), with a short preventive video intervention (guided breathing exercise). This group is used to explore the tool's sensitivity to change and short-term preventive impact.
