A-AB-yd-mq-v-2-pSelfreport on 16 questions

Did you yesterday..?
A smile and laugh a lot
B were you proud of something?
C learn or do something interesting
D did you feel enjoyment?
E did you feel love?
F would you like to have more days like yesterday?
H did you feel feel well rested?
I were you treated with respect?
J were you able to choose how you spend your time?
K did you have good tasting food?

Did you feel a lot yesterday
L worry
M sadnes
N depression
O boredom
P anger
Q shame

Rated:
1: yes
0: no

Computation:
- Average % positive affect = (A-K)/10
- Average % negative affect = (L-Q)/6
- Affect Balance = Average % positive affect - Average % negative affect

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?

Appendix 2: Statistics used
SymbolExplanation
rPRODUCT-MOMENT CORRELATION COEFFICIENT (Also "Pearson's correlation coefficient' or simply 'correlation coefficient')
Type: test statistic.
Measurement level: Correlate: metric, Happiness: metric
Range: [-1; +1]

Meaning:
r = 0 no correlation ,
r = 1 perfect correlation, where high correlate values correspond with high happiness values, and
r = -1 perfect correlation, where high correlate values correspond with low happiness values.
