Observed Relation with Happiness
T3 happiness by male sex (sample D):
female male difference
T2 and T3 happiness by male sex (sample A+B):
female male difference
happiness at T3 Mt'= 6.25 Mt'= 6.26 +.01
Interaction sex x time (non-significant):
T2 to T3 +.07 +.05 -.02
Significance assessed by variance-analysis, also involving employment.
The original depression score is ranging from
4 to 28. Mt' is standardized into a happpiness score (0-10 and reversed)
Possible testing effects checked by comparing three sub-samples:
- sample A: selected at T1, tested at T1, T2, T3
- sample B: selected at T1, tested at T2 and T3
- sample C: selected at T1, tested at T3 only
At T3 happiness appeared lower in sample A than in sample B, but there is little evidence for systematic testing effects.
