Brief 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. 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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Test-Retest Reliability (ICC) of the WB6Dim Internal Tension Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability. |
| Test-Retest Reliability (ICC) of the WB6Dim Sleep and Recovery Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability. |
| Test-Retest Reliability (ICC) of the WB6Dim Energy Reservoir Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability. |
| Test-Retest Reliability (ICC) of the WB6Dim Self-Esteem Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability. |
| Test-Retest Reliability (ICC) of the WB6Dim Emotional Climate Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability. |
| Test-Retest Reliability (ICC) of the WB6Dim Cognitive Saturation Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability. |
| Test-Retest Reliability (ICC) of the WB6Dim Hyperconnection Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1.Higher values indicate greater temporal stability. |
| Test-Retest Reliability (ICC) of the WB6Dim Perceived Autonomy Dimension | Day 0 to Day 3 | ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Contamination Rate at T2 | Day 3 | Proportion of T1/T2 pairs excluded due to a significant life event reported at T2 contamination control question. Reported as percentage. |
| ICC Comparison Between Contamination-Free and Contaminated Pairs | Day 0 to Day 3 | Exploratory comparison of ICC(1,1) estimates across all 8 WB6Dim dimensions between contamination-free and contaminated pairs, to assess direction and magnitude of contamination effects. |
