Summary
This study developed iSTART, a novel web-app using mHealth technology to prevent substance use among college students, particularly at Hispanic Serving Institutions. The innovative program aims to reduce substance use risks and related consequences through a 30-day intervention.
Area of Science:
- Public Health
- Digital Health
- Substance Use Prevention
Background:
- College students face persistent challenges in substance use prevention despite existing strategies.
- Increasing reliance on web-based technology among young adults necessitates innovative mHealth solutions.
- Hispanic Serving Institutions require tailored approaches to address substance use risks in diverse student populations.
Purpose of the Study:
- To describe the rationale, development, and design of iSTART, a novel web-app intervention for substance use prevention.
- To leverage mobile health (mHealth) technology to mitigate substance use and related consequences in college populations.
- To create a sustainable and innovative program for diverse college campuses, including Hispanic Serving Institutions.
Main Methods:
- The iSTART web-app was developed using the intervention mapping protocol in collaboration with stakeholders and a substance abuse prevention partner.
- A 30-day multi-module intervention was designed based on theoretical constructs: attitudes, risk perceptions, normative re-education, and refusal skills.
- The intervention will be evaluated using a time series design with 600 students randomly assigned to intervention, comparison, or control groups.
Main Results:
- The study is currently in the design and development phase, with evaluation planned.
- The iSTART web-app integrates key behavior change strategies and theoretical constructs.
- The intervention targets attitudes, risk perceptions, social norms, and self-efficacy related to substance use.
Conclusions:
- The iSTART web-app presents an innovative and sustainable approach to substance use prevention in college settings.
- Successful implementation could significantly contribute to the evidence base for mHealth interventions in higher education.
- The program is designed to be adaptable for diverse student populations, including those at Hispanic Serving Institutions.

01:17Drug Dependence
1.2K
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...

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
653
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...

01:26Drug Administration and Therapy Phases: Overview
733
Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
