Operationalization
Closed questions rated on an 11 point scale. Assessed at T1 and T2.
'Residual  changes scores' computed by by first regressing T2-scores on T1- scores :
- ^Satisfaction T2^= a + b * Sat T1.
-  Residual change = Sat T2-^Sat T2^.
Residual change is in fact the deviation of an individuals satisfaction at T2 from the average T2- satisfaction of Ss who were equally satisfied at T1.

Happiness Measure Statistics Elaboration / Remarks O-SLW-c-sq-n-10-a r = +.33 Happiness assessed at T1 and T2.

 O-SLW-c-sq-n-10-a Beta = +.29 ß controlled for satisfaction with health.

also involving : change in health satisfaction, change in income, change in employment, change in health and age.
Change in satisfaction with income related to change in income (ßL=+.15)  and loss of job (ßL=-.18), which in their turn  are related  to age (resp. ßL=-.09 and -.08)
