This study explored the relationship between low emotional intelligence and substance-use problems in adults. One hundred and forty-one participants completed the Self-Administered Alcoholism Screening Test [1, 2], the Drug Abuse Screening Test [3], an emotional intelligence scale [4], and a measure of psychosocial coping [5]. Low emotional intelligence was a significant predictor of both alcohol-related problems and drug-related problems. Poorer coping predicted drug-related problems, but not alcohol-related problems. Coping was not found to be a significant mediator between emotional intelligence and substance-use problems. Possible implications for intervention and treatment efforts are discussed.
