Motivation as a Mechanism for Daily Experiences' Effects on HIV Medication Adherence.
The Journal of the Association of Nurses in AIDS Care : JANAC
|October 3, 2017
Summary
Medication adherence for people with HIV (PLWH) is difficult. Daily factors like motivation, mood, and social support impact adherence to antiretroviral therapy, highlighting the need for personalized care.
Area of Science:
- Behavioral Science
- Public Health
- Infectious Disease
Background:
- Medication adherence is crucial for managing HIV, yet a gap often exists between patient intentions and actual behavior.
- People living with HIV (PLWH) face unique challenges in maintaining consistent adherence to antiretroviral therapy (ART).
Purpose of the Study:
- To investigate the intention-behavior gap in daily medication adherence among PLWH.
- To test a theoretical model explaining how daily experiences influence ART adherence.
Main Methods:
- Smartphone-based surveys and electronic pill bottles were used to collect daily data from 87 PLWH over 10 weeks.
- Multilevel analyses examined relationships between daily variables, motivation, and adherence in 58 participants.
Main Results:
- Despite generally well-controlled HIV, adherence was only 73% on study days.
- Four of five daily measures predicted motivation for ART, which in turn predicted adherence.
- Control beliefs, mood, and social support indirectly influenced adherence; stress and coping did not.
Conclusions:
- Daily experiences significantly impact ART adherence in PLWH, even those with controlled HIV.
- Healthcare providers should inquire about daily fluctuations in motivation to improve adherence strategies.

266
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:10Retrovirus Life Cycles
49.9K
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...

01:20Motivational Cycle
1.2K
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...

01:25Motivational Bias
416
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
