An observational study of Psychological Well Being, run by Clover Link at 1 site in France.
Trial summary
This study aims to establish the test-retest reliability of the WB6Dim digital self-assessment tool across its eight well-being dimensions, using a 3-day interval protocol designed to minimize the probability of genuine well-being changes between assessments. Read more about this study

About this study
Official title: Psychometric Validation of Test-Retest Reliability of the WB6Dim Digital Self-Assessment Tool for Well-Being Using a 3-Day Interval Protocol and Contamination Control
This study aims to establish the test-retest reliability of the WB6Dim digital self-assessment tool across its eight well-being dimensions, using a 3-day interval protocol designed to minimize the probability of genuine well-being changes between assessments.
Participants complete the 28-item WB6Dim questionnaire at baseline (T1) and again 3 days later (T2). A single contamination control question at T2 identifies participants who experienced a significant life event during the interval; these pairs are excluded from primary ICC analyses and retained for exploratory analyses.
An optional third assessment at 9 weeks (T3) provides preliminary exploratory data on sensitivity to change following access to a well-being program. T3 is not part of the primary design.
Read the detailed description
The first validation study of the WB6Dim instrument (NCT07301879) established strong internal consistency and convergent validity across N=295 participants. Test-retest reliability was assessed over a 14-day interval on N=92 usable pairs, yielding preliminary ICC estimates ranging from .49 to .77. However, the 14-day interval is methodologically suboptimal for a dynamic monitoring tool: real-life events occurring during two weeks cannot be distinguished from instrument instability, and confidence intervals were wide due to the limited number of pairs.
The present study addresses these limitations through three improvements. First, the interval is reduced to 3 days, substantially reducing contamination risk while avoiding memory-based response bias. Second, a contamination control question is administered at T2 to identify and exclude pairs where a significant life event occurred. Third, the target of N=220 usable pairs produces 95% confidence intervals with maximum width of .20 across all dimensions, meeting the precision threshold for definitive psychometric publication.
Only the 28 WB6Dim items are administered, with no additional gold-standard scales, reducing response burden to approximately 3 minutes per session. Participant matching is performed via email address.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
