Insights

The Self-Perception Profile for Children (SPPC) is a valid and reliable tool for assessing self-concept in children recently diagnosed with chronic illnesses. This study confirms its psychometric properties in this specific pediatric population.

Area of Science:

  • Pediatric Psychology
  • Psychometrics
  • Child Health

Background:

  • The Self-Perception Profile for Children (SPPC) is widely used to measure children's self-concept.
  • Limited research exists on the SPPC's psychometric properties in children newly diagnosed with chronic illnesses.

Purpose of the Study:

  • To evaluate the psychometric properties of the SPPC in children newly diagnosed with chronic conditions.
  • To confirm the reliability and validity of the SPPC for this population.

Main Methods:

  • Confirmatory factor analysis was performed on the SPPC.
  • Reliability, convergent validity, and discriminant validity were assessed.
  • The study included 31 children with newly diagnosed asthma, diabetes, epilepsy, food allergy, or juvenile arthritis.

Main Results:

  • The SPPC's unidimensionality across domains was confirmed.
  • Robust internal reliability (α=.83-.95) and varied inter-domain correlations (ρ=.05-.85) were found.
  • Convergent validity was supported by global self-concept and quality of life measures; discriminant validity was shown for Global Self-worth in relation to comorbid mental disorders.

Conclusions:

  • The SPPC demonstrates valid and reliable psychometric properties for children newly diagnosed with chronic illnesses.
  • These findings support the use of the SPPC in clinical and research settings involving pediatric chronic conditions.

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.

Self-Evaluation: Self-Enhancement and Self-Verification

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...

Self-Concept01:19

Self-Concept

Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Social Foundations of Self II: The Generalized Other

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Self-Discrepancy and Its Effects

Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

Self-Discrepancy Theory

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.
