Full text	Selfreport on single question: How happy are you these days? Response options not reported
Classification	O-HL-c-sq-v-0-a
Author's label	happiness
Page in publication	214,215
Remarks	The mean is the weighted mean of all 4 waves. Because neither the range, nor the start value of the range was given, the transformed value cannot be calculated. Given the M however it is plausible that it is a 3 point range 1-3; or a 4 point range 0-3 or 1-4 In the first case the transformed value on the range 0-10 is:5,5 in the second case it is 7,0 or 3.67 Comparison with the General Life Satisfaction item makes the transformed value of 7.0 the most probable
Error estimates	Overtime correlation: T1-T2: r=+.34; T1-T3: r=+.24; T1-T4: r=+.29
