Subgroup Differences

As most of you know, screening and brief interventions (SBIs… sometimes referred to as SBIRTs, which indicate SBI + referral [R] to treatment [T]) have been historically used for the purpose of timely substance abuse screening and treatment in primary care.

However, this effect was only statistically significant in men. Although there are potential explanations for this finding (e.g., a smaller proportion of females vs. males who consume unhealthy levels of alcohol, social desirability associated with female vs. male consumption of alcohol), this got me thinking about RIPPLE.

What do you think? For example, there’s the possibility we may observe subgroup differences in parents of overweight and obese children vs. normal weight children, parents of females vs. males, and parents of children vs. adolescents.

  1. Interesting issue, Jill. While we won’t be collecting weight-related data from parents in our study, that could be a factor that influences how parents respond to the information they receive from RIPPLE. Another thing to consider in thinking / planning about the follow-up study…or perhaps we should ask parents about their perception of their own weight status (?).
