Summary
Frustrated psychological needs negatively impact health. This study developed and validated the Psychological Need Frustration Scale for Physical Activity (PNFS-PA) to measure these negative experiences in physical activity settings.
Area of Science:
- Psychology
- Health and Physical Activity
Background:
- Frustration of basic psychological needs is detrimental to health.
- A validated scale for measuring need frustration in physical activity is currently lacking.
- Self-determination theory provides the framework for understanding these needs.
Purpose of the Study:
- To develop and validate the Psychological Need Frustration Scale for Physical Activity (PNFS-PA).
- To provide a reliable measure for assessing negative psychological experiences within physical activity contexts.
Main Methods:
- Item pool creation and face/content validity assessment (Study 1).
- Exploratory structural equation modeling (ESEM) for factor structure (Study 2).
- Cross-validation of factor structure, nomological validity, reliability, and measurement invariance (Study 3).
Main Results:
- The developed PNFS-PA scale demonstrated a clear factor structure.
- The scale was found to be reliable and valid through rigorous testing.
- Evidence supported the scale's nomological validity and measurement invariance.
Conclusions:
- The Psychological Need Frustration Scale for Physical Activity (PNFS-PA) is a valid and reliable instrument.
- The PNFS-PA can be effectively used to assess psychological need frustration in physical activity.
- This scale contributes to understanding and addressing negative psychological experiences in physical activity.

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.

The human need for self-esteem has long intrigued psychologists, leading to the development of several theories that explore its evolutionary and functional significance. Among the most influential are the sociometer, hierometer, and terror management theories. Each offers a unique perspective on why people strive for self-worth and how it shapes behavior and social interaction.Sociometer TheoryAccording to sociometer theory, self-esteem functions as an internal gauge of social acceptance.

860
Abraham Maslow's theory of motivation, introduced in 1943, is widely known as the "Hierarchy of Needs." This theory posits that human needs are arranged in a hierarchical structure, starting with basic survival needs and progressing toward more complex psychological and self-fulfillment desires. The hierarchy is typically a pyramid, and the lower needs must be satisfied to reach the next level.
At the pyramid's base are physiological needs, including food, water, and shelter...

972
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

01:20Motivational Cycle
987
The motivational cycle is a key concept that explains how individuals are motivated to meet their needs. At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...
