Summary
Motivational interviewing (MI) can improve pre-exposure prophylaxis (PrEP) use for HIV prevention. However, varied intervention details limit understanding of MI
Area of Science:
- Public Health
- Behavioral Science
- HIV Prevention Research
Background:
- Pre-exposure prophylaxis (PrEP) is effective in reducing HIV risk, yet uptake and adherence are suboptimal in vulnerable populations.
- Motivational interviewing (MI) shows promise for enhancing HIV prevention behaviors, but its specific impact on PrEP initiation and adherence requires further investigation.
- Existing research lacks comprehensive details on the essential components of MI-based interventions for improving PrEP utilization.
Purpose of the Study:
- To conduct a scoping review of MI-based interventions aimed at improving PrEP initiation and adherence.
- To identify and examine key intervention components, including session characteristics, counselor attributes, and interview content.
- To synthesize findings regarding the application and effectiveness of MI in PrEP strategies.
Main Methods:
- A systematic search was conducted across PubMed, CINAHL Plus, Embase, and Web of Science databases.
- Articles published between 2012 and 2023, utilizing MI for PrEP initiation or adherence, were included.
- Seven studies met the inclusion criteria for the review.
Main Results:
- Intervention components varied significantly, with MI session durations ranging from 15 to 60 minutes.
- Counselor characteristics (credentials, demographics) and MI content (PrEP education, barrier identification, strategy development) were diverse across studies.
- The heterogeneity and lack of detailed reporting across studies limit the assessment of MI's efficacy and replicability.
Conclusions:
- Motivational interviewing is a valuable component in interventions designed to enhance PrEP initiation and adherence.
- The variability in intervention design and reporting hinders a definitive evaluation of MI's effectiveness and the replication of successful strategies.
- Further research with standardized reporting is needed to optimize MI-based interventions for PrEP uptake and adherence.

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.

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

The motivational cycle is a key concept that explains how individuals are motivated to meet their needs. At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

01:10Retrovirus Life Cycles
46.3K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
