Friendship Self-Regulation Questionnaire SRQ-F

Abstract

The Friendship Self-Regulation Questionnaire (SRQ-F) is a specialized psychometric instrument designed to assess the underlying motivational reasons a person maintains a specific close friendship. Grounded in Self-Determination Theory (SDT), the SRQ-F evaluates the degree to which an individual feels autonomous versus controlled in their relational engagement. The scale organizes responses along a continuum of self-regulation, spanning from highly controlled motivation, such as external regulation and introjected regulation, to autonomous motivation, including identified regulation and intrinsic motivation. The primary focus of the SRQ-F is to quantify the subjective experience of freedom and volition associated with participating in a particular friendship.

Purpose

The core purpose of the SRQ-F is to diagnose the quality of motivation driving an individual’s commitment to a friendship. Unlike instruments that merely measure satisfaction or frequency of interaction, the SRQ-F aims to distinguish between different types of regulatory styles—why a person engages with a friend. This differentiation is critical for understanding the stability, quality, and psychological health benefits derived from the relationship, as SDT posits that more autonomous motivation leads to greater well-being and persistence.

Specifically, the scale helps researchers and clinicians determine the extent to which relational behaviors (e.g., spending time together, listening to problems, keeping promises) are driven by internal enjoyment and value (autonomous regulation) versus external pressures, avoidance of guilt, or seeking external rewards (controlled regulation).

Construct

The SRQ-F measures the construct of self-regulation in the domain of close friendships, operationalizing the motivational continuum derived from the SDT framework. This continuum includes four distinct regulatory styles:

• External Regulation: Behavior controlled by external contingencies, such as rewards or threats (e.g., “My friend would get mad at me if I didn’t”).
• Introjected Regulation: Behavior driven by internal pressures, such as guilt, anxiety, or the maintenance of self-esteem (e.g., “I would feel guilty if I withdrew from the friendship”).
• Identified Regulation: Behavior accepted as personally important and valued, even if not inherently enjoyable (e.g., “I believe it is an important personal attribute to live up to my promises”).
• Intrinsic Motivation: Behavior performed purely for the inherent pleasure and satisfaction derived from the activity itself (e.g., “I enjoy the numerous crazy and amusing moments that we share”).

Validity

While specific detailed validity studies for the SRQ-F subset are often found within broader SRQ publications, the scale is typically validated by demonstrating its alignment with SDT principles. Studies generally confirm strong construct validity, showing that scores reflecting more autonomous regulation (identified and intrinsic motivation) correlate positively with established markers of relationship quality, psychological well-being, and relationship stability. Conversely, controlled regulation scores (external and introjected) tend to correlate with negative relationship outcomes, conflict, and relational distress, providing evidence of criterion validity consistent with the underlying theory.

Reliability

The reliability of the SRQ-F is generally assessed through measures of internal consistency, such as Cronbach’s alpha, for the subscales corresponding to the four regulatory styles. Research commonly reports high reliability coefficients (alphas typically ranging from .70 to .90) for the intrinsic and identified regulation subscales, which form the Autonomous Motivation Index. Reliability for the controlled subscales (external and introjected) may sometimes be slightly lower but remains within acceptable psychometric ranges, confirming that items within each regulatory cluster measure a coherent aspect of motivational regulation in friendships.

Factor Analysis

Factor analysis of the SRQ-F typically supports a four-factor structure corresponding to the four specified regulatory styles (external, introjected, identified, and intrinsic). Alternatively, researchers often employ higher-order factor analysis to confirm a two-factor structure: Controlled Motivation (combining external and introjected) and Autonomous Motivation (combining identified and intrinsic). The factor structure confirms that the items successfully discriminate between different levels of internalization and autonomy, supporting the use of a Relative Autonomy Index (RAI) score calculated by weighting and summing the subscale scores.

Instrument

Test Type: Self-report Questionnaire

Format: 7-point Likert scale (ranging from 1 = not at all true to 7 = very true)

Language Available: English (Original), translations likely exist given the broad use of the SRQ family.

Population Group: Adolescents and Adults

Age Group: Typically 16 years and older, used widely in college and general adult populations.

Population Details: Individuals who are currently involved in a specific, close friendship that they are asked to reference when completing the items.

Test Methodology: Respondents are asked to select a particular friendship and then rate how true various reasons are for their continued participation in that relationship. Scoring involves calculating separate subscale scores and often a composite Relative Autonomy Index (RAI).

Permissions & Fee and Test Year

The Self-Regulation Questionnaires, including the SRQ-F, are generally available for non-commercial academic research use without charge, consistent with the open-access philosophy of the SDT researchers. Permission requests should be directed to the authors or the official Self-Determination Theory website: http://selfdeterminationtheory.org. The specific test year is not provided in the source, but the SRQ series was developed primarily in the 1990s and early 2000s.
