PSYCHOLOGICAL FACTORS IN SMOKING, DRINKING, AND DRUG EXPERIMENTATION.

The article presents a study, which investigates common psychological factors in smoking, drinking and drug experimentation. The study yielded a replication of earlier findings that the MMPI PD scale tended to relate to both smoking and experimentation with drugs. Other than the PD scale, however, no test scores correlated significantly with any two of the social health habits considered. Smoking was positively correlated with the neurotic scales of the MMPJ, with the DJT scale for aggression and with report of psychological problems to the interviewers.
