Summary
Internalized motivation and intrinsic motivation are key to Argus II retinal prosthesis user engagement and satisfaction. External motivation and amotivation showed weaker associations with device use and perceptions.
Area of Science:
- Biomedical Engineering
- Ophthalmology
- Psychology
Background:
- The Argus II retinal prosthesis aims to restore vision for individuals with retinitis pigmentosa.
- Understanding user motivation is crucial for optimizing device adoption and long-term engagement.
Purpose of the Study:
- To investigate the relationship between different types of motivation (Self-determination Theory) and user engagement with the Argus II retinal prosthesis.
- To explore how motivation influences satisfaction and adherence to the device.
Main Methods:
- Nine Argus II users completed the Situational Motivation Scale (SIMS) and the Argus Questionnaire (AQ).
- Spearman correlations were used to analyze associations between motivation types and user-reported outcomes.
- AQ assessed decision-making, self-perception, utility, perceived competence, and family support.
Main Results:
- Identified regulation and intrinsic motivation were significantly associated with key aspects of Argus II use, including self-perception and perceived utility.
- Engagement and satisfaction were linked to both identified regulation and intrinsic motivation.
- External regulation showed a negative association with family support, while amotivation was linked to self-perception.
Conclusions:
- Self-determination theory provides a framework for understanding Argus II device motivation.
- Clinicians can leverage motivational insights to enhance user confidence, internalization, and adherence.
- Supporting intrinsic and identified motivation may improve outcomes for retinal prosthesis users.

Self-Determination Theory (SDT), formulated by Richard Ryan and Edward Deci, explains that human motivation is driven by three fundamental psychological needs: autonomy, competence, and relatedness. When these needs are met, individuals experience personal growth, intrinsic motivation, and overall well-being.
Autonomy is the need to feel in control of one's actions and decisions. For example, a student who chooses their research topic is likely to be more engaged and motivated than one who...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

17
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...

The human need for self-esteem has long intrigued psychologists, leading to the development of several theories that explore its evolutionary and functional significance. Among the most influential are the sociometer, hierometer, and terror management theories. Each offers a unique perspective on why people strive for self-worth and how it shapes behavior and social interaction.Sociometer TheoryAccording to sociometer theory, self-esteem functions as an internal gauge of social acceptance. It...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
