Observed Relation with Happiness

Happiness Measure Statistics Elaboration / Remarks M-FH-c-sq-v-3-b OR = T1 happiness (age 14) by later canabis use (vs never) as reported at T2 (age 21)

Odd Ratios denote chance of being UNhappy. Sign of correlation reversed to fit standard notation in WDH M-FH-c-sq-v-3-b OR = - s/ns T1 Happy (vs Very happy) by onset of canabis use (vs never) at age
- 15 or less OR = 2.09 CI95[1.17, 3.71]
- 16-17      OR = 1.35 CI95[0.93, 1.95]
- 18 or more OR = 1.54 CI95[0.93, 2.56] M-FH-c-sq-v-3-b OR = - p < .05 T1 UNhappy (vs very happy) by onset of canabis use (vs never) at age
- 15 or less OR = 3,57 CI95[1.91-6,68]
- 16-17      OR = 2,79 CI95[1.67-4,69]
- 18 or more OR = 2,00 CI95[1.04-3,87] O-SLW-c-sq-v-3-b OR = - s/ns T1 Satisfied (vs Very satisfied) by onset of canabis use (vs never) at age
- 15 or less OR = 2.09 CI95[1.17, 3.71]
- 16-17      OR = 1.35 CI95[0.93, 1.95]
- 18 or more OR = 1.54 CI95[0.93, 2.56] O-SLW-c-sq-v-3-b OR = - s/ns T1 Dissatisfied (vs Very satisfied) by onset of canabis use (vs never) at age
- 15 or less OR = 7.62 CI95[3.42, 16.97]
- 16-17      OR = 2.25 CI95[1.09,  4.65]
- 18 or more OR = 5.02 CI95[2.33, 10.85]
