Internet-delivered treatment for substance abuse: a multisite randomized controlled trial
The American Journal of Psychiatry
|April 5, 2014
Summary
The Therapeutic Education System (TES), an internet-delivered intervention, reduced dropout rates and increased abstinence for substance use disorder patients. This digital approach shows promise for improving addiction treatment accessibility and outcomes.
Area of Science:
- Digital Health
- Addiction Medicine
- Behavioral Science
Background:
- Computer-delivered interventions can enhance access to quality addiction treatment.
- The Therapeutic Education System (TES) is an internet-delivered behavioral intervention incorporating motivational incentives.
Purpose of the Study:
- To evaluate the effectiveness of the Therapeutic Education System (TES) as a clinician-extender for substance use disorder treatment.
- To assess TES's impact on abstinence rates and treatment dropout.
Main Methods:
- 507 adult outpatients were randomized to treatment as usual (TAU) or TAU plus TES for 12 weeks.
- TES involved 62 interactive modules and motivational incentives, substituting for 2 hours of weekly standard care.
- Primary outcomes included abstinence (urine drug screens, self-report) and time to dropout.
Main Results:
- The TES group exhibited significantly lower dropout rates (HR=0.72) and higher abstinence rates (OR=1.62) compared to TAU.
- These positive effects were more pronounced in patients with a positive initial drug or alcohol screen (OR=2.18).
Conclusions:
- Internet-delivered interventions like TES can expand access and improve addiction treatment outcomes.
- Further research is warranted to assess TES in diverse clinical settings and isolate component effects.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
1.6K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

01:17Drug Dependence
1.9K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

01:11Clinical Trials: Overview
4.7K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

01:28Dosage Regimens: Designs and Approaches
600
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

01:11Blinding
2.9K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
