Self-Efficacy01:29

Self-Efficacy

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...
Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

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-Esteem01:28

Self-Esteem

Self-esteem, a core aspect of psychological well-being, reflects an individual's positive and negative self-evaluation in terms of worth, competence, and overall value. It is both a stable trait and a dynamic process, influenced by experiences and social interactions across the lifespan. While global self-esteem offers a general assessment, research highlights that self-esteem is multidimensional and varies across specific life domains.Domain-Specific Self-EsteemResearchers have delineated...
Self-Report Tests of Personality01:22

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
Sources of Self-Esteem II: Performance Feedback01:24

Sources of Self-Esteem II: Performance Feedback

Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem: self-efficacy,...
Social Foundations of Self III: Self-Evaluation01:30

Social Foundations of Self III: Self-Evaluation

Self-evaluation is the process by which individuals assess their abilities, behaviors, and characteristics based on feedback from others. Charles H. Cooley observed that a person’s self-perception is primarily influenced by how others see and judge them. He suggested that individuals form their identities based on their interpretations of others' reactions. As a result, social interactions play a crucial role in shaping self-esteem and personal identity. These external evaluations often blend...

Area of Science:

  • Psychology
  • Public Health
  • Pharmacology

Background:

  • Self-efficacy is crucial for improving HIV medication adherence.
  • Existing tools for measuring HIV medication-taking self-efficacy are limited.
  • This study addresses the need for a reliable and valid assessment tool.

Purpose of the Study:

  • To examine the psychometric properties of the HIV Medication Taking Self-efficacy Scale.
  • To validate a tool for measuring self-efficacy in HIV medication adherence.
  • To provide a reliable measure for research and clinical practice.

Main Methods:

  • Cross-sectional, correlational design with 326 participants in the USA (2003-2007).
  • Administered six self-report questionnaires, including the HIV Medication Taking Self-efficacy Scale.
  • Assessed reliability, criterion validity, and construct validity.

Main Results:

  • Participants reported high self-confidence in medication-taking tasks (mean=8.31) and perceived medication effectiveness (mean=8.56).
  • The scale and subscales showed excellent reliability (α=0.93–0.94).
  • Criterion validity was established through correlations with physiological, psychological factors, and adherence (r=-0.20–0.58).

Conclusions:

  • The HIV Medication Taking Self-efficacy Scale is a psychometrically sound measure.
  • The scale is suitable for researchers and clinicians working with people with HIV.
  • Findings inform interventions to enhance self-efficacy and medication adherence in people with HIV.
