Observed Relation with Happiness

Happiness Measure Statistics Elaboration / Remarks O-SLW-c-sq-v-3-b = CHANGE happiness between age 14-21 by age of onset alcohol problems (vs no problems).

Problems with alcohol in adolescence go with a decline of happiness in adolescence, the younger first problem experienced, the greater the loss in happiness
O-SLW-c-sq-v-3-b OR = - ns/05 Satisfied (vs Very satisfied)
- 18 years or more    OR = 1.03 CI95[0.75,1.44]
- 16-17 years         OR = 1.75 CI95[1.08,2.84]
- 15 years or less    OR = 1.37 CI95[0.63,2.91]
O-SLW-c-sq-v-3-b = Dissatisfied (vs Very satisfied) M-FH-c-sq-v-3-b = Happy (vs Very happy) M-FH-c-sq-v-3-b = Unhappy (vs Very happy)

ORs denote positive correlations with UNhappiness. The standarde notation in the WDH is from less to more happiness and hence the direction of correlation is noted above as negative (-)

T2 happiness controled for T1 happiness to capture change

ORs similsr when additionally controled for T2:
- gender
- employment
- on welfare
- in school
- education
- living arrangement
- has boy/girl friend
