title: Geophysical variables and behavior: LXV. Seasonal changes in mood in opioid addicts on the Addiction Research Center Inventory.
abstract: Seasonal changes in mood using the Addiction Research Center Inventory (ARCI) were tested in 243 male opioid addicts when they were free of drug and withdrawal effects. No significant changes were found on scales which measure euphoria (MBG), tension-anxiety (LSD), excitement (Ex), or dysphoric effects (SOW). A significant difference between seasons was found for lowered motivation (PCAG) in the summer and spring relative to winter, but these effects were not consistent with a winter seasonal affective disorder. Significant changes were more common for spring-fall and summer seasons relative to winter on items of the inventory.
