The document discusses intervening variables (IVs) and contributing factors (CFs) in the context of understanding community problems with alcohol and drug use. It defines IVs as the reasons or facilitators for substance use in a community, and CFs as more specific circumstances where use is occurring. An example is provided of availability being an IV and lack of ID checks by clerks being a CF. The document also notes that IVs and CFs will be important factors to consider in subsequent steps of a strategic prevention framework process, such as building capacity or planning interventions.
