Sources of Self-Esteem I: Family Experience

167
Self-esteem, a crucial component of psychological development, is significantly shaped by familial experiences. The early parent-child relationship serves as a foundational influence on a child's self-concept, with long-lasting effects extending into adolescence and adulthood.Parental Behaviors and Early Self-Esteem FormationEmpirical studies have identified four principal parental behaviors that foster healthy self-esteem in children. These include expressions of acceptance, affection, and...

Erikson's Theory on Socioemotional Development during Adolescence

1.1K
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 "What is my place in...

Self-Schemas

35.3K
In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Self-Evaluation: Self-Enhancement and Self-Verification

5.7K
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...

Factorial Design02:01

Factorial Design

13.7K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Self-Report Tests of Personality01:22

Self-Report Tests of Personality

752
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.

Area of Science:

  • Developmental Psychology
  • Nutritional Science
  • Behavioral Health

Background:

  • Eating autonomy influences nutrition-related disease risk (obesity, diabetes).
  • Limited understanding of eating autonomy development in adolescents due to a lack of validated survey tools.
  • Need for a comprehensive measure of adolescent eating autonomy behavioral engagement.

Purpose of the Study:

  • To develop and validate a comprehensive survey for assessing adolescent eating autonomy.
  • To explore the factor structure and psychometric properties of the new eating autonomy survey.
  • To examine associations between eating autonomy dimensions and demographic factors.

Main Methods:

  • Iterative item development, content validity, expert review, and exploratory factor analysis (EFA) were employed.
  • A sample of 355 U.S. adolescents (12-17 years) completed the new survey along with measures of parental autonomy support and feeding practices.
  • Maximum Likelihood EFA identified 5 factors: Snack Autonomy, Breakfast and Lunch Autonomy, Food Purchasing and Independence, Parent-granted Autonomy, and Contextual control in eating.

Main Results:

  • The final 28-item survey demonstrated a 5-factor structure, distinct from established constructs.
  • Females reported higher autonomy in most areas.
  • Autonomy varied with age (3 factors), food insecurity (2 factors), and BMI (1 factor).

Conclusions:

  • The study successfully developed and validated a survey to quantify dimensions of adolescent eating autonomy.
  • Findings provide initial insights into demographic variations in eating autonomy.
  • Further scale analyses are recommended for wider adoption; understanding adolescent eating autonomy is crucial for health outcomes.
