Data from two national studies of treatment spanning two decades-Treatment
Outcome Prospective Study (TOPS), 1979 to 1981, and Drug Abuse Treatment Ou
tcome Studies for Adolescents (DATOS-A), 1993 to 1995-provided a comparison
of treatment and services provided to 261 TOPS and 1.519 DATOS-A intreatme
nt adolescent patients in a cross-modality sample of 24 TOPS and 31 DATOS-A
programs. The authors used patient self-reports of treatment needs and ser
vices received to compare unmet needs for six services. Findings showed a g
eneral decline over treatment eras in services received that was only parti
ally offset by significant decreases in some self-reported service needs in
DATOS-A. Unmet needs increased significantly over treatment eras for speci
fic services, including psychological, family, employment, and financial se
rvices. Potential explanations include changes in treatment access and decr
eases in program resources for services.
