Self-efficacy and substance abuse: assessment using a brief phone interview

Area of Science:

• Addiction research
• Psychology of substance abuse
• Behavioral health

Background:

• Self-efficacy is crucial for avoiding substance use and is linked to positive treatment outcomes.
• Previous research primarily focused on smoking and alcohol; this study examines crack-cocaine users.
• Assessing self-efficacy during and after treatment is vital for understanding recovery maintenance.

Purpose of the Study:

• To assess self-efficacy in a predominantly crack-cocaine-using population during and one month after treatment.
• To evaluate the reliability and viability of a brief, phone-administered self-efficacy measure.
• To explore the relationship between self-efficacy and abstinence from cocaine and other substances.

Main Methods:

• A cohort of 186 patients, 61% reporting crack-cocaine use, were interviewed post-treatment.
• Self-efficacy was measured using a brief, 4-item phone interview.
• Data were compared to an established self-efficacy measure to assess the brief measure's validity.

Main Results:

• Patient self-efficacy significantly increased from during treatment to one month post-treatment.
• Higher self-efficacy ratings at follow-up were associated with abstinence from cocaine and other substances.
• The brief, phone-administered self-efficacy measure yielded results comparable to established instruments.

Conclusions:

• Self-efficacy plays a role in the maintenance of abstinence among individuals with substance use disorders, particularly crack-cocaine users.
• A brief, phone-based self-efficacy assessment is a reliable and viable tool for clinical settings.
• These findings support the integration of self-efficacy measurement into addiction treatment and follow-up protocols.
