Behavior Regulation Exercise Questionnaire (BREQ-2)

Abstract

The Behavior Regulation Exercise Questionnaire (BREQ-2) is a widely used psychological instrument designed to assess an individual’s motivation for engaging in physical exercise. Developed as a revision of the original BREQ, the BREQ-2 specifically incorporated a measure of amotivation, aligning its structure more closely with the continuum proposed by Self-Determination Theory (SDT). This scale differentiates between various types of behavioral regulation, ranging from non-self-determined (amotivation and external regulation) to highly self-determined (intrinsic motivation), providing a nuanced understanding of why individuals choose, or fail, to exercise.

Purpose

The primary purpose of the BREQ-2 is to quantify the degree to which an individual’s participation in exercise is regulated by different motivational styles, as conceptualized within the framework of Self-Determination Theory (SDT). By measuring these distinct regulatory styles, researchers and practitioners can better understand the underlying psychological drivers that predict adherence to exercise programs and overall physical activity behavior.

The secondary purpose, and the key modification from the original BREQ, was the inclusion of items specifically assessing amotivation. This addition ensures a comprehensive assessment across the entire motivational continuum, allowing for the calculation of the Relative Autonomy Index (RAI), a global score of self-determined motivation.

Construct

The BREQ-2 measures five distinct types of behavioral regulation related to exercise, all derived from the continuum of Self-Determination Theory. These factors capture the quality, rather than just the quantity, of motivation, moving from non-regulation to fully autonomous regulation.

The five measured factors are:

  • Amotivation: Represents a lack of intent or desire to engage in exercise, often due to a perceived lack of value or competence.
  • External Regulation: Behavior is controlled by external rewards or punishments (e.g., exercising because others insist).
  • Introjected Regulation: Behavior is regulated by internal pressure, such as feelings of guilt or shame (e.g., exercising to avoid feeling bad).
  • Identified Regulation: Behavior is performed because the individual personally values the outcomes and goals of exercise (e.g., exercising for health benefits).
  • Intrinsic Motivation: Behavior is performed purely for the inherent pleasure and satisfaction derived from the activity itself (e.g., exercising because it is fun).

Validity

The original research supporting the BREQ-2 by Markland and Tobin (2004) demonstrated strong evidence for its factorial validity. Confirmatory factor analysis confirmed that the 19 items appropriately load onto the five hypothesized subscales (Amotivation, External, Introjected, Identified, and Intrinsic Regulation). This five-factor structure is consistent with the theoretical postulates of the Self-Determination Theory continuum.

Furthermore, the scale exhibits strong construct validity through its ability to predict relevant behavioral outcomes, such as adherence and persistence in physical exercise. The calculated Relative Autonomy Index (RAI), which weights the subscales according to their position on the autonomy continuum, consistently correlates positively with measures of exercise engagement, providing robust support for the theoretical underpinning of the instrument.

Reliability

The internal consistency of the BREQ-2 subscales is generally high, as measured by Cronbach’s alpha coefficients reported during the development of the modification. These reliability estimates confirm that the items within each factor cohere well, providing stable measures of the respective regulatory styles.

The reported internal consistency values are:

  • Amotivation: 0.83
  • External Regulation: 0.79
  • Introjected Regulation: 0.80
  • Identified Regulation: 0.73
  • Intrinsic Motivation Regulation: 0.86

These values indicate acceptable to strong internal consistency across all subscales, suggesting reliable measurement, particularly for Intrinsic Motivation and Amotivation.

Factor Analysis

The development of the BREQ-2 utilized confirmatory factor analysis (CFA) to establish its dimensional structure. The analysis confirmed the hypothesized five-factor model, supporting the differentiation between the five motivational regulations: Amotivation, External Regulation, Introjected Regulation, Identified Regulation, and Intrinsic Motivation. This structure represents a significant theoretical improvement over the original BREQ, which only included four factors, by fully representing the motivational continuum.

The item groupings for the factors are detailed as follows:

  • Amotivation (items: 5, 9, 12, and 19)
  • External Regulation (items: 1, 6, 11, and 16)
  • Introjected Regulation (items: 2, 7, and 13)
  • Identified Regulation (items: 3, 8, 14, and 17)
  • Intrinsic Motivation Regulation (items: 4, 10, 15, and 18)

Instrument

Test Type: Self-report questionnaire, psychological assessment scale.

Format: 19 items rated on a 5-point Likert scale, ranging from 0 = “not true for me” to 4 = “very true for me.”

Language Available: Primarily English; various translations (e.g., Spanish, French, German) have been validated in subsequent studies across different cultures.

Population Group: General population, specializing in individuals engaged in or considering physical exercise and sport.

Age Group: Adolescents and Adults.

Population Details: The scale is typically used with adult samples, including university students, community members, and those participating in recreational or competitive exercise activities.

Test Methodology: The scale yields five distinct subscale scores. These scores are often combined using a weighted formula to generate the Relative Autonomy Index (RAI), which serves as a single continuous measure reflecting the overall level of self-determination in exercise behavior. The RAI formula is: RAI = (-3 * Amotivation) + (-2 * External regulation) + (-1 * Introjected regulation) + (+2 * Identified regulation) + (+3 * Intrinsic regulation).
