Summary
This study validated the Basic Psychological Needs scale for renal dialysis patients, confirming its reliability and usefulness in assessing autonomy and competence to understand self-care behaviors.
Area of Science:
- Psychology
- Nephrology
- Healthcare
Background:
- Intrinsic motivation is influenced by basic psychological needs.
- The link between self-care behaviors and these needs in renal dialysis patients remains under-explored.
- This study addresses this gap by evaluating a specific measurement scale.
Purpose of the Study:
- To assess the validity and reliability of the Basic Psychological Needs scale.
- To determine if the scale is a suitable tool for patients undergoing renal dialysis.
- To explore factors influencing self-care behaviors in this population.
Main Methods:
- 120 patients undergoing renal dialysis in Busan Metropolitan City participated.
- The Basic Psychological Needs scale, comprising autonomy and competence factors, was administered.
- Data were analyzed using SPSS 21.0 and AMOS 21.0.
Main Results:
- The scale demonstrated high reliability, with Cronbach's alpha at 0.90 for all items.
- Subfactor reliability was 0.90 for autonomy and 0.72 for competence.
- Internal consistency and various forms of validity (construct, convergent, discriminant, criterion-related) were confirmed.
Conclusions:
- The Basic Psychological Needs scale is a valid and reliable instrument.
- It can be effectively used to measure the basic psychological needs of patients on renal dialysis.
- Findings support the scale's utility in research and clinical practice for this patient group.

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...

Maslow's hierarchy is described with the help of a pyramidal shape. The most fundamental needs, physiological needs, are at the bottom of the pyramid.
Physiological needs such as hunger, thirst, sex, physical comfort, and survival are at the bottom of the pyramid. These are the components that are necessary to sustain life. Once the first level of needs has been met, the second level arises.
Safety needs include stability and predictability. Protection and freedom from danger are all a part...

01:17Erikson's Theory on Socioemotional Development during Adolescence

Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and...

Erik Erikson, a stage theorist, adapted Freud's theory to emphasize social factors in personality development throughout life, a concept known as psychosocial development. Unlike Freud, who focused on early childhood, Erikson believed that personality evolves across eight life stages, each marked by a specific challenge or "crisis." Successful resolution of each stage fosters competence, while failure may lead to feelings of inadequacy.

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...

Abraham Maslow, a prominent figure in humanistic psychology, developed a theory centered on self-actualization, which he placed at the top of his hierarchy of needs. According to Maslow, self-actualization represents achieving one's full potential and is a rare accomplishment attained by approximately 2% of the population. Maslow identified notable historical figures such as Thomas Jefferson, Mahatma Gandhi, Helen Keller, and Martin Luther King Jr. as examples of self-actualized...
