title: Contribution of education to health and life satisfaction in older adults mediated by negative affect.
abstract: OBJECTIVE
  The authors developed a model of relationships between two enduring attributes (educational attainment and negative affect) and two indicators of successful aging (health and life satisfaction).
  
  
  METHODS
  A probability sample of 1,177 participants (age 55 and older) were interviewed four times at 6-month intervals.  Structural equation models were developed based on the authors' hypothetical model proposing a mediating effect of negative affect between health and successful aging.
  
  
  RESULTS
  As predicted, education and negative affect both were directly related to health and life satisfaction.  Also, as predicted, negative affect mediated the relationship between education and successful aging indicators.
  
  
  CONCLUSIONS
  Education appears to confer a lifelong advantage for healthy aging.  Part of this advantage is accounted for by the relationship between education and trait negative affect.  Higher educational attainment is related to lower levels of trait negative affect; lower negative affect results in better health and life satisfaction.
