Summary
The Commitment to Physical Activity Scale (CPAS) is a reliable and valid tool for assessing physical activity commitment in young girls. This scale measures values, attitudes, and motivation, supporting its use in research and practice.
Area of Science:
- Pediatric Exercise Science
- Psychometrics
- Behavioral Health
Background:
- Assessing children's commitment to physical activity is crucial for promoting lifelong health behaviors.
- Existing measures may not fully capture the multifaceted nature of physical activity commitment in preadolescent girls.
Purpose of the Study:
- To evaluate the psychometric properties of the Commitment to Physical Activity Scale (CPAS).
- To determine the reliability and validity of the CPAS in a sample of third-to fifth-grade girls.
Main Methods:
- A cohort of 932 girls in grades 3-5 completed the CPAS pre- and post-intervention.
- Psychometric evaluation included internal consistency, factor analysis, and concurrent validity assessments.
- Concurrent validity was examined by correlating CPAS subscales with physical activity frequency.
Main Results:
- Factor analysis revealed three distinct CPAS factors: values, attitudes, and motivation.
- Reliability coefficients for the CPAS subscales ranged from .429 to .821.
- Significant correlations were observed between CPAS subscales and self-reported physical activity frequency.
Conclusions:
- The Commitment to Physical Activity Scale (CPAS) demonstrated good reliability and validity in third-to fifth-grade girls.
- The findings support the CPAS as a suitable instrument for measuring overall commitment to physical activity in this demographic.
- The CPAS can be utilized in research and clinical settings to understand and promote physical activity engagement in young females.

01:22Self-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.
01:29Five-Factor Theory of Personality
The five-factor model, often called the Big Five personality traits, is widely accepted in psychology as a comprehensive framework for understanding personality. These five traits — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism — are often remembered using the acronym OCEAN.
Openness reflects creativity, curiosity, and openness to new experiences. Individuals scoring high in openness are imaginative, have a wide range of interests, and are independent thinkers. Low...

01:24Cattell's 16 Personality Factors
Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the fundamental,...

01:29Self-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...
01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
