Drug Services Research Survey US (DSRS-1990)
Parent Series Details:
Study Details:
The Drug Services Research Survey (DSRS) was initiated to
collect detailed information on the characteristics of drug treatment
facilities and the clients discharged from those facilities in the
United States. Data were collected between June and December of 1990
in two phases. In Phase I, facility-level information was gathered via
telephone interviews with facility directors and drug treatment
providers in a national sample of drug treatment facilities. The
questionnaire included point prevalence estimates for March 30,
1990. Phase II involved site visits to a sample of Phase I
facilities. This visit included an in-person interview with the
facility director or administrator and the collection of client-level
data from a sample of client records. Record abstractions were done
for clients discharged from these facilities between September 1,
1989, and August 31, 1990. Follow-up of the clients to assess
post-treatment status was conducted in the SERVICES RESEARCH OUTCOMES
STUDY, 1995-1996: [UNITED STATES].
Study Scope
Time period:
1990
Collection date:
1990-06/1990-12
Geographic coverage :
United States
Unit of observation:
individual, facility
Data types:
administrative records data
Universe:
(1) Substance abuse treatment facilities in the United
States as identified by NIDA's National Drug and Alcoholism Treatment
Unit survey (NDATUS) or NIDA's Substance Abuse Facility Identification
System (SAFIS) Master Facility Inventory of known facilitie
Notes:
The study was conducted by the Schneider Institute
for Health Policy, Brandeis University. The data were collected and
prepared by Westat, Inc.
The original data collection included two
files for the Facility Telephone Interview, a file with imputed values
and a file without imputed values. This release includes only the
file with imputed values. Please see the processor notes for
instructions for resetting imputed values to missing.
The Phase I
Facility Telephone Interview file originally included data for 1,986
records. However, one record had missing data on every variable and
was subsequently deleted from this release.
The telephone facility
data file treats service units as the base unit of analysis.
Accordingly, there are more records than sampled facilities in this
file. For facilities operating more than one service unit, the first
record was treated as the "Master Facility Record" and included valid
data on all the variables. Each subsequent service unit for the
facility includes valid data only for those variables that apply to
the service unit. Missing data that are provided on the master
facility record are coded -4: "Not Master Facility".
Subject Terms:
- drug abuse
- drug treatment
- treatment compliance
- treatment facilities
- treatment programs
Study Methodology
Sample:
This study employed a multistage stratified sample design.
For Phase I, each of the facilities in the Drug Services Research
Survey frame was assigned to one of six strata based on prior
knowledge of the services provided by the facility: (1) hospital
inpatient treatment, (2) residential treatment, (3) outpatient
detoxification or maintenance treatment, (4) outpatient drug-free, (5)
facilities providing alcohol treatment only, (6) facilities for which
the types of services were unknown. Different sampling rates were
applied across the strata. In all, 1,183 facilities were selected in
Phase I. In Phase II, a subsample of 120 facilities from strata one
through four (the drug treatment modality strata) were subsampled and
21 records (20 regular records plus one alternate) of discharged
clients were abstracted from these facilities, resulting in 2,222
completed abstracts. Weights are included in the data files to allow
users to calculate population parameter estimates, adjust unequal
probabilities of selection in the sample, and minimize the biases
arising from nonresponse.
Versions:
- 2008-10-08: New files were added. These files included one or more of the following: Stata setup, SAS transport (CPORT), SPSS system, Stata system, SAS supplemental syntax, and Stata supplemental syntax files, and tab-delimited ASCII data file.
Extent of processing:
- Performed consistency checks.
- Standardized missing values.
- Created online analysis version with question text.
- Performed recodes and/or calculated derived variables.
- Checked for undocumented or out-of-range codes.
