Socially-discordant individuals used stimulants more often during intervention, according to a recent study. Researchers investigated 270 individuals receiving study intervention for stimulant abuse/dependence through the multi-site Stimulant Reduction Intervention using Dosed Exercise (CTN-0037) trial. They found:

• Using mixed effects modeling, results indicated that individuals with baseline social discord used stimulants on more days throughout the intervention period than those without social discord.
• An interaction between gender, usual living arrangements, and satisfaction with those arrangements indicated that women who lived alone and were dissatisfied with that arrangement reported greater days of stimulant use compared to several other groups.
• Finally, individuals who reported usually living with a non-partner over the past 3 years attended a greater percentage of intervention sessions compared to those usually living with a partner.
