Abstract:
This thesis tested a path model of the relationships of reasons for drinking and
reasons for limiting drinking with consumption of alcohol and drinking problems. It was
hypothesized that reasons for drinking would be composed of positively and negatively
reinforcing reasons, and that reasons for limiting drinking would be composed of
personal and social reasons. Problem drinking was operationalized as consisting of two
factors, consumption and drinking problems, with a positive relationship between the
two. It was predicted that positively and negatively reinforcing reasons for drinking
would be associated with heavier consumption and, in turn, more drinking problems,
through level of consumption. Negatively reinforcing reasons were also predicted to be
associated with drinking problems directly, independent of level of consumption. It was
hypothesized that reasons for limiting drinking would be associated with lower levels of
consumption and would be related to fewer drinking problems, through level of
consumption. Finally, among women, reasons for limiting drinking were expected to be
associated with drinking problems directly, independent of level of consumption. The
sample, was taken from the second phase of the Niagara Young Aduh Health Study, a
community sample of young adult men and women. Measurement models of reasons for
drinking, reasons for limiting drinking, and problem drinking were tested using
Confirmatory Factor Analysis. After adequate fit of each measurement model was
obtained, the complete structural model, with all hypothesized paths, was tested for
goodness of fit. Cross-group equality constraints were imposed on all models to test for
gender differences. The results provided evidence supporting the hypothesized structure
of reasons for drinking and problem drinking. A single factor model of reasons for
limiting drinking was used in the analyses because a two-factor model was inadequate.
Support was obtained for the structural model. For example, the resuhs revealed
independent influences of Positively Reinforcing Reasons for Drinking, Negatively
Reinforcing Reasons for Drinking, and Reasons for Limiting Drinking on consumption.
In addition. Negatively Reinforcing Reasons helped to account for Drinking Problems
independent of the amount of alcohol consumed. Although an additional path from
Reasons for Limiting Drinking to Drinking Problems was hypothesized for women, it
was of marginal significance and did not improve the model's fit. As a result, no sex
differences in the model were found. This may be a result of the convergence of drinking
patterns for men and women. Furthermore, it is suggested that gender differences may
only be found in clinical samples of problem drinkers, where the relative level of
consumption for women and men is similar.
