Our classificationIntrinsic motivation
Self-reports on three questions:
A. If I am not good at something, I would rather keep 
struggling to master it than move on to something I may 
be good at.
B. I would rather do something at which I feel 
confident and relaxed than something which is 
challenging and difficult (reversed scoring).
C. I more often attempt tasks that I am not sure I can 
do than tasks I believe I can do.

O-Sum---sq-vt-11-aSelfreport on single questions:

This measure of average happiness in nations combines responses to different questions on happiness and life-satisfaction rated on different scales. Precise items and rating scales differ per nation. Average scores per nation were transformed afterwards to a common 0-10 scale.

Name: Diener's SWB-score of nations

Appendix 2: Statistics used
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]

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.
