Our Classification
Remarks
Change marital between T1 in 1980 and T6 in 2000
Distribution
T1 1980: M = 1,64 SD = 0,42
T2 1983:

Average marital satisfaction follows a slight U-curve over these 20 years, which is most pronounced among respondents who were low in marital satisfaction at baseline
Operationalization
Change in marital happiness over  20 years asssed using selfreport on 7 questions in each of the 6 waves:
a:
b;
c:
d:
e:
f:
Rated:
0: not too happy
1: pretty happy
2: very happy

Computation: (a+b+c+d+e+f)/2 recoded to 5 step ordinal scale

Change reduced to 3 trajectories
1: Decrease:marital satisfaction was low and went down (21%)
0: Stability
     0a: marital satisfaction  remained high (38%)
     0b:  marital satisfaction remaind  at a middle level (41%)

Observed Relation with Happiness

Happiness Measure Statistics Elaboration / Remarks O-HL-c-sq-v-3-ca b-fix = + s T1 happiness by T1-T6 change in marital satisfaction in three trajectories
- stable high     (vs low)    b = +.12 (05)
- stable middele  (vs low)    b = +.07 (ns)
- low and decline (vs stable) b = -.12 (001)

b control for change in other trajectories
O-HL-c-sq-v-3-ca b-fix = -.24 p < .001 - stable high     (vs low)    b = +.15 (05)
- stable middele  (vs low)    b = +.10 (ns)
- low and decline (vs stable) b = -.24 (001)
when b additionally controled for:
- Children below age 18
- family income
- use of public assistance
- wife employed full time
- wife extended hours
- husband employed
O-HL-c-sq-v-3-ca b-fix = + s b unaffected by additional control for:
- Gender relations
  - husband share of household work
  - shared decision making
- values
  - religiousness
  - traditional gender attitude

Together, the positive correlation with maintaining a high level of marital satisfaction and the negative correlation with decrease in marital satisfaction denote a positive effect of T1 lifesatisfaction on later marital satisfaction
O-HL-c-sq-v-3-ca OR = + s T1 happiness by membership of T1-T6 trajectory of change in atisfaction with marriage
- constant high:     OR = 3,74 (001)
- constant middle:   OR = 1,17 (ns)
- low and declining: OR = 0.23 (001)

OR controled for T1:
- Family sitiation
  - age at first marriage
  - marital duration
  - homogamity in race and education
  - parental divorce
  - premarital cohabitation
- Education: level of highest
- Economic: log family income
