Abstract:

OBJECTIVE: This study examined the extent to which perceived social support is related to longitudinal treatment outcomes among heavy drinkers randomized to a brief, telephone-based care management intervention versus standard care. METHOD: This is a secondary analysis of data from a randomized trial comparing an enhanced, brief alcohol intervention to standard care. Participants comprised 136 male, heavy drinkers (mean age = 57.3 years) receiving primary care at Corporal Michael J. Crescenz Veterans Affairs Medical Center clinics. Participants in the intervention arm received a telephone-based care management intervention focused on helping patients reduce their alcohol use. Primary measures included the Timeline Followback method for number of heavy drinking days and the Multidimensional Scale of Perceived Social Support for self-reported baseline social support. RESULTS: Although there was no significant main effect for baseline perceived social support on number of heavy drinking days over time, there was a significant three-way interaction (Perceived Social Support × Randomization Group × Time). Specifically, among patients reporting high support, those randomized to the intervention arm experienced significantly greater declines in number of heavy drinking days over time. Conversely, among patients reporting low support, those randomized to standard care experienced more improvement over the course of followup. CONCLUSIONS: Perceived social support may be related to differential outcomes depending on whether patients are in care management or standard care. For those receiving brief intervention, certain therapy techniques may mobilize pre-existing social resources and/or enhance the ability for patients to use their social supports, suggesting the need for replication and further research in understanding this interaction.
