Study looked to determine the strength of the relationship between smoking, depression, intention to smoke, and several psychosocial and environmental factors. Participants completed the Multiscore Depression Inventory (MDI) and items regarding smoking behavior. Analyses found that participants were more likely to smoke if parents smoked, if scores on MDI indicated instrumental helplessness and social isolation, or if they were older.
