California Drug and Alcohol Treatment Assessment (CALDATA-1991-1993)

<p>The California Drug and Alcohol Treatment Assessment<br /> (CALDATA) was designed to study the costs, benefits, and effectiveness<br /> of the state's alcohol and drug treatment infrastructure (recovery<br /> services) and specifically to assess (1) the effects of treatment on<br /> participant behavior, (2) the costs of treatment, and (3) the economic<br /> value of treatment to society. Data were collected on participants<br /> (clients) across four types of treatment programs, or modalities:<br /> residential, residential "social model," nonmethadone outpatient, and<br /> outpatient methadone (detoxification and maintenance). Data were<br /> collected in two phases. In Phase 1, treatment records were abstracted<br /> for clients who received treatment or were discharged between October<br /> 1, 1991, and September 30, 1992. In Phase 2, these clients were<br /> located and recruited for a follow-up interview. The CALDATA design<br /> and procedures included elements from several national treatment<br /> outcome studies including the Drug Services Research Survey, Services Research Outcomes Study, National<br /> Treatment Improvement Evaluation Study, and Drug Abuse<br /> Treatment Outcome Study. The record abstract was designed<br /> to collect identifying and locating information for interview<br /> reference during the personal interviewing phase. The abstract also<br /> collected demographic, drug, or alcohol use, and treatment and service<br /> information. The follow-up questionnaire covered time periods before,<br /> during, and after treatment and focused on topics such as ethnic and<br /> educational background, drug and alcohol use, mental and physical<br /> health, HIV and AIDS status, drug testing, illegal activities and<br /> criminal status, living arrangements and family issues, employment and<br /> income, and treatment for drug, alcohol, and mental health<br /> problems. Drugs included alcohol, barbiturates, benzodiazepines,<br /> cocaine powder, crack, downers, hallucinogens, heroin, illegal<br /> methadone, inhalants, LSD, marijuana/hashish/THC, methamphetamines and<br /> other stimulants, narcotics, over-the-counter drugs, PCP, ritalin or<br /> preludin, and sedatives/hypnotics. CALDATA was originally known as the<br /> California Outcomes Study (COS).This study has 1 Data Set.</p>
