| HELPrct | R Documentation |
The HELP study was a clinical trial for adult inpatients recruited from a detoxification unit. Patients with no primary care physician were randomized to receive a multidisciplinary assessment and a brief motivational intervention or usual care, with the goal of linking them to primary medical care.

Data frame with 453 observations on the following variables.
age subject age at baseline (in years)
anysub use of any substance post-detox: a factor with levels no yes
cesd Center for Epidemiologic Studies Depression measure at baseline (high scores indicate more depressive symptoms)
d1 lifetime number of hospitalizations for medical problems (measured at baseline)
daysanysub time (in days) to first use of any substance post-detox
dayslink time (in days) to linkage to primary care
drugrisk Risk Assessment Battery drug risk scale at baseline
e2b number of times in past 6 months entered a detox program (measured at baseline)
female 0 for male, 1 for female
sex a factor with levels male female
g1b experienced serious thoughts of suicide in last 30 days (measured at baseline): a factor with levels no yes
homeless housing status: a factor with levels housed homeless
i1 average number of drinks (standard units) consumed per day, in the
past 30 days (measured at baseline)
i2 maximum number of drinks (standard units) consumed per day, in the
past 30 days (measured at baseline)
id subject identifier
indtot Inventory of Drug Use Consequences (InDUC) total score (measured at baseline)
linkstatus post-detox linkage to primary care (0 = no, 1 = yes)
link post-detox linkage to primary care: no yes
mcs SF-36 Mental Component Score (measured at baseline, lower scores indicate worse status)
pcs SF-36 Physical Component Score (measured at baseline, lower scores indicate worse status)
pss_fr perceived social support by friends (measured at baseline, higher scores indicate more support)
racegrp race/ethnicity: levels black hispanic other white
satreat any BSAS substance abuse treatment at baseline: no yes
sexrisk Risk Assessment Battery sex risk score (measured at baseline)
substance primary substance of abuse: alcohol cocaine heroin
treat randomized to HELP clinic: no yes
Eligible subjects were adults, who spoke Spanish or English, reported alcohol, heroin or cocaine as their first or second drug of choice, resided in proximity to the primary care clinic to which they would be referred or were homeless. Patients with established primary care relationships they planned to continue, significant dementia, specific plans to leave the Boston area that would prevent research participation, failure to provide contact information for tracking purposes, or pregnancy were excluded.
Subjects were interviewed at baseline during their detoxification stay and follow-up interviews were undertaken every 6 months for 2 years. A variety of continuous, count, discrete, and survival time predictors and outcomes were collected at each of these five occasions.
This data set is a subset of the HELPmiss data set restricted to
the 453 subjects who were fully observed on the
age, cesd, d1,
female, sex, g1b, homeless,
i1, i2, indtot, mcs, pcs, pss_fr,
racegrp, satreat, substance, treat,
and sexrisk variables. (There is some missingness in the other variables.)
HELPmiss contains 17 additional subjects with
partially observed data on some of these baseline variables. This is
also a subset of the HELPfull data which includes 5 timepoints and
many additional variables.
The HELPrct data set was originally named HELP but has
been renamed to avoid confusion with the help function.
