Traces longitudinal patterns of alcohol-related problems and alcoholic remission over four years. A sample of 922 male alcoholics was assessed at the time of admission to treatment and at several followup points; at four years, the data included interviews and validating information for survivors, and official causes of death for those deceased. The analysis identifies factors associated with remission, relapse, and alcohol-related death over the four-year period. Patterns of psychological functioning and social adjustment are also examined and related to drinking behavior. Methodological analyses assess the validity of self-reports and the extent of potential bias due to nonresponse. Results show that although about half of the cohort was in remission at four years, remissions were generally intermittent rather than stable over long periods of time.

The major findings of this study are as follows: (1) Simple cross section estimates grossly underestimate cohort profiles during the period 1960-70. Furthermore the growth in earnings is not uniform across experience groups and more recent vintages tend to have steeper profiles in most fields. Consequently the rate of return or present value comparisons based on cross sections are likely to be misleading even if the standard adjustment for growth is made. (2) For purposes of estimating mean profiles and mean effects of variables estimates based on pooled independent cross sections are quite close to those based on the more expensive longitudinal data. (3) There are important persistent unmeasured individual effects on both the level and growth of earnings. Consequently, individuals with the same observed characteristics will still have a wide variance in their permanent income.
