Our Classification
Participants were randomly assigned to either treatment or control group
Number of daily gratitude statements: M = 4.49
within person variance= 1.13; between person variance= .61
1: TREATMENT: Direct question asked each day during 2 weeks: "There are many things in our lives, both large and small, that we might be grateful about. Think back over the day and write down on the lines below all that you were grateful today."
Participants could describe up to 6 things for which they were grateful.
0 CONTROL Recorded daily affects like the treated group, but did not do the gratitude exercise

Observed Relation with Happiness

Happiness Measure Statistics Elaboration / Remarks A-AB-md-mqr-n-7-e d = + ns Across person CHANGE: Treatment (vs control)
- Positive affect: d = +.19 (s?)
- Negative affect: d = +.02 (ns)
Hence non-significant positive effect on Affect Balance.
A-AB-md-mqr-n-7-e Beta = + p < .01 Within person CHANGE in treated group
- Positive affect: Beta= +.58 (01)
- Negative affect: Beta= -.44 (01)
Hence significant positive effect on Affect Balance

Cross-lagged analysis does not shown a causal effect of gratitude on happiness, but rather from happines on gratitude

The study distinguished betweem 'active' and 'deactive' positive and negative affect and found only active positive effect significant (05). The above coefficient for total PA and NA were computed by the WDH team.
