Appendix 1: Happiness measures used
CodeFull Text
A-AB-yd-mq-v-2-uSelfreport on 2 questions:

Did you experience the following feelings during A LOT OF THE DAY yesterday?
A enjoyment
B depression

Rated: : 0: no 1: yes

Computation:
- Average % positive affect = A
- Average % negative affect = B
- Affect Balance = A-B


These questions do not measure hedonic level of affect of individual persons adequately, since yesterday's mood does not always correspond with typical average mood. Yet these questions can be used for measuring hedonic level in agregates, such as nations, since individual variations balance out in big samples.
C-BW-c-sq-l-11-cSelfreport on single question:

Here is ladder representing the 'ladder of life'. Let's suppose the top of the ladder represents the best possible life for you; and the bottom, the worst possible life for you. On which step of the ladder do you feel you personally stand at the present time?

This question was followed (not preceded) by items on life 5 years ago and 5 years from now.


Appendix 2: Statistics used
SymbolExplanation
bREGRESSION COEFFICIENT (non-standardized) by LEAST SQUARES (OLS)
Type: test statistic
Measurement level: Correlate: metric, Happiness: metric
Theoretical range: unlimited

Meaning:
b > 0 A higher correlate level corresponds with a higher happiness rating on average.
B < 0 A higher correlate level corresponds with a lower happiness rating on average.
B = 0 Not any correlation with the relevant correlate.
DMtDIFFERENCE of MEANS AFTER TRANSFORMATION
Type: descriptive statistic only.
Measurement level: Correlate: dichotomous, Happiness: metric
Theoretical range: [-10; +10]

Meaning: the difference of the mean happiness (happiness measured at a 0-10 rating scale) between the two correlate levels.
