Interventions

BEHAVIORALBrief Behavioral Therapy for Insomnia (BBTI)

Brief Behavioral Therapy for Insomnia (BBTI) focuses primarily on stimulus control and sleep restriction as well as sleep hygiene recommendations delivered over 2 in-person sessions and 2 brief telephone boosters and is designed to be implemented by nonspecialists in primary care or other non-clinical settings. The intervention is manualized, and clients utilize sleep diaries and workbook assignments to consolidate recommendations.

BEHAVIORALBrief Alcohol Screening and Intervention for College Students (BASICS)

Brief Alcohol Screening and Intervention for College Students (BASICS) is a manualized brief intervention targeting alcohol use and consequences among high risk drinkers and includes both personalized feedback regarding drinking norms, consequences, and motives for drinking, as well as protective behavioral skills for reducing heavy episodic drinking and related consequences. BASICS is delivered in a motivational interviewing (MI) style (Miller \& Rollnick, 2002) to enhance intrinsic motivation to change drinking and implement protective behavioral strategies. BASICS has been adapted to target marijuana use and has been adapted for use with a variety of populations.
