Response patterns of the Spanish version of the 49-item short form of the Addiction Research Center Inventory after the use of sedatives, stimulants, and opioids.

This report examines the validity of the Spanish version of the 49-item short form of the Addiction Research Center Inventory (ARCI) for measuring subjective effects after the use of sedatives, stimulants, and opioids. Data from four clinical trials in which this questionnaire was used have been analyzed. The Spanish ARCI short form was found to be sensitive in measuring subjective effects after the administration of alcohol, triazolam, and flunitrazepam (sedatives), cocaine (stimulants), and morphine, pentazocine, and naloxone (opioids) and to distinguishing among them. The response patterns were similar to those previously reported for the same drugs with the English version of ARCI. It is concluded that Spanish version of the 49-item short form of ARCI is a valid instrument for assessing the subjective effects of psychoactive drugs in the Spanish-speaking population context.
