after taking into account other individual and situational factors as well as pre-intervention AP levels. In previous studies, it has been difficult to assess to what extent ensuing reductions are due to unique effects of individual and situational factors, above and beyond other confounding variables. In the present study, findings for the effects of being a female, experiencing a serious incident and being a less heavy drinker cannot be considered an artifact of omitted baseline confounding factors because these confounded effects were statistically adjusted. There may be other factors that were not considered in the present study. However, the individual and situational factors considered in the present study, as well as the alcohol use controls, represent most of the factors that have been discussed in the literature.
