Abstract

Objective This study examined the relationships between treatment fidelity and treatment outcomes in a community-based trial of a 12-Step Facilitation (TSF) intervention.Method In a prior multi-site randomized clinical trial, 234 participants in 10 outpatient drug treatment clinics were assigned to receive the Stimulant Abuser Groups to Engage in 12-Step (STAGE-12) intervention. A secondary analysis reviewed and coded all STAGE-12 sessions for fidelity to the protocol, using the Twelve Step Facilitation Adherence Competence Empathy Scale (TSF ACES). Linear mixed-effects models tested the relationship between three fidelity measures (adherence, competence, empathy) and six treatment outcomes (number of days of drug use and five Addiction Severity Index (ASI) composite scores) measured at 3 months post-baseline.Results Adherence, competence and empathy were robustly associated with improved employment status at follow up. Empathy was inversely associated with drug use, as was competence in a non-significant trend (p=.06). Testing individual ASI drug composite score items suggested that greater competence was associated with fewer days of drug use and, at the same time, with an increased sense of being troubled or bothered by drug use.Conclusions Greater competence and empathy in the delivery of a TSF intervention were associated with better drug use and employment outcomes, while adherence was associated with employment outcomes only. Higher therapist competence was associated with lower self-report drug use, and also associated with greater self-report concern about drug use. The nature of TSF intervention may promote high levels of concern about drug use even when actual use is low.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
