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.

Study groupRoleWhat they receive
Cohort C - Test-Retest ReliabilityAdult volunteers recruited from a health and well-being newsletter subscriber base. Participants complete the 28-item WB6Dim digital self-assessment at baseline (T1) and again 3 days later (T2). A contamination control question at T2 identifies participants who experienced a significant life event during the interval. An optional third assessment (T3) is completed at 9 weeks by participants who voluntarily accessed a well-being program after T2 completion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Test-Retest Reliability (ICC) of the WB6Dim Internal Tension Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

  2. Test-Retest Reliability (ICC) of the WB6Dim Sleep and Recovery Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

  3. Test-Retest Reliability (ICC) of the WB6Dim Energy Reservoir Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

  4. Test-Retest Reliability (ICC) of the WB6Dim Self-Esteem Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

  5. Test-Retest Reliability (ICC) of the WB6Dim Emotional Climate Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

  6. Test-Retest Reliability (ICC) of the WB6Dim Cognitive Saturation Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

  7. Test-Retest Reliability (ICC) of the WB6Dim Hyperconnection Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1.Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

  8. Test-Retest Reliability (ICC) of the WB6Dim Perceived Autonomy Dimension

    ICC(1,1) on contamination-free T1/T2 pairs. Score range: 0 to 1. Higher values indicate greater temporal stability.

    Measured: Day 0 to Day 3

Secondary outcomes (2)
  1. Contamination Rate at T2

    Proportion of T1/T2 pairs excluded due to a significant life event reported at T2 contamination control question. Reported as percentage.

    Measured: Day 3

  2. ICC Comparison Between Contamination-Free and Contaminated Pairs

    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.

    Measured: Day 0 to Day 3

Individual data sharing
No: 13:12All collected data are fully anonymized at the point of entry. No individual-level identifiable data are stored or processed. Participant email addresses are used solely for matching T1 and T2 responses and are not retained after study completion. All analyses are conducted on aggregated, pseudonymized numerical data only. IPD sharing is therefore not applicable.
