Sense of Belonging Scale

Abstract

The Sense of Belonging Scale (SOBS), developed by Dawn Anderson-Butcher and David E. Conroy in 2002, is a psychometric instrument designed to measure psychological belonging and perceived membership among children and adolescents within youth development programs, extracurricular activities, and community-based agencies. Grounded in positive youth development (PYD) paradigms and social-psychological models of relational connectedness, the instrument captures an adolescent’s subjective appraisal of safety, acceptance, institutional inclusion, commitment, and perceived relational support. Comprising five concisely phrased self-report items, the SOBS utilizes a developmentally sensitive four-point categorical response format ranging from 1 (“NO!”) to 4 (“YES!”), purposefully designed with dichotomous capitalization to maximize semantic clarity and cognitive accessibility for younger respondents. Psychometric evaluations across diverse community and out-of-school samples have consistently demonstrated robust internal consistency, with Cronbach’s alpha coefficients regularly ranging from .88 to .92. Confirmatory factor analyses (CFA) corroborate an unequivocal unidimensional factorial architecture, yielding high standardized factor loadings (λ = .71–.88) and exceptional model fit indices. The scale exhibits sound construct, convergent, and predictive validity, correlating significantly with sustained program participation, self-efficacy, prosocial behaviors, and protective outcomes against internalizing and externalizing problems. Because of its brevity, strong psychometric properties, and non-commercial accessibility, the SOBS serves as an essential tool for developmental researchers, youth service evaluators, and educational practitioners seeking to assess relational climate and socio-emotional integration in non-formal learning settings.

Authors

The Sense of Belonging Scale was conceptualized, operationalized, and psychometrically validated through a collaborative scholarly partnership:

• Dawn Anderson-Butcher, Ph.D., LSW, ACSW: Professor at the College of Social Work, The Ohio State University. Dr. Anderson-Butcher is a nationally recognized authority in school social work, community-based positive youth development, organizational collaboration, and expanded school improvement models. Her research focuses on community agency practices, physical activity-based youth development programs (such as the LiFEsports initiative), and systemic mechanisms that support vulnerable youth.
• David E. Conroy, Ph.D.: Professor of Kinesiology and Human Development and Family Studies at The Pennsylvania State University. Dr. Conroy’s scholarship focuses on motivation, health behavior change, achievement goals, developmental psychology in physical activity contexts, and advanced quantitative methodologies in psychometric scale development.

Subsequent operationalization and cross-sector field validation were conducted in partnership with Janet S. Fink (University of Massachusetts Amherst) and within program evaluation syntheses led by Ronald M. Sabatelli and Stephen A. Anderson (University of Connecticut).

Purpose

The primary purpose of the Sense of Belonging Scale (SOBS) is to provide an empirically rigorous, theoretically grounded, and pragmatically brief metric of psychological belonging within youth-serving contexts. Youth development programs—such as community recreation centers, Boys & Girls Clubs, 4-H organizations, after-school academic enrichment hubs, and sport-based youth development leagues—rely fundamentally on their capacity to cultivate an inclusive climate. Prior to the introduction of the SOBS, existing measures of belongingness were either tailored almost exclusively to formal primary and secondary school classrooms (e.g., the Psychological Sense of School Membership scale) or were excessively lengthy, cognitively taxing, and linguistically inaccessible for young or at-risk populations participating in drop-in or community settings.

Anderson-Butcher and Conroy (2002) designed the instrument to fulfill both evaluative and diagnostic functions. In research and program evaluation, the SOBS enables researchers to operationalize relational climate as a mediating or moderating mechanism. It helps determine whether positive developmental trajectories (e.g., academic tenacity, emotional regulation, resilience) are causally supported by an adolescent’s subjective integration into the programmatic microsystem. Clinically and programmatically, the scale functions as an early warning monitoring tool: depressed belongingness scores identify youths at heightened risk for program drop-out, disengagement, and social alienation, allowing frontline youth workers, counselors, and mentors to implement tailored relational interventions.

Furthermore, the SOBS satisfies the demand for rapid, low-burden assessment protocols within out-of-school-time (OST) sectors. Administering a lengthy survey often detracts from programmatic engagement and compromises response validity due to survey fatigue. By capturing the core essence of subjective membership in five straightforward statements, the SOBS bridges empirical rigor and administrative viability, making continuous quality improvement feasible across community-based youth human service organizations.

Psychological Construct

The construct assessed by the SOBS is context-specific psychological belonging, defined as the subjective experience of feeling accepted, integrated, valued, and emotionally invested within an organized social collective or program. Far from being a passive reflection of physical attendance, psychological belonging represents a multi-faceted socio-emotional state characterized by cognitive appraisals of inclusion, affective sensations of interpersonal security, and behavioral commitment to the community.

The five items of the SOBS systematically map onto key relational facets that delineate a complete psychological bond between an individual and an organizational setting:

• Psychological Safety and Comfort (Item 1: “I feel comfortable at this program.”): Evaluates the individual’s baseline perception of freedom from emotional threat, stigmatization, or ridicule. Subjective comfort establishes the psychological safety necessary for youth to engage authentically with peers and mentors without fear of judgment.
• Structural and Symbolic Integration (Item 2: “I feel I am a part of this program.”): Captures self-categorization and perceived group membership. The adolescent conceptualizes themselves not as an outsider or peripheral visitor, but as an integral constituent of the social fabric of the agency.
• Behavioral and Affective Commitment (Item 3: “I am committed to this program.”): Taps into the reciprocal dedication the youth directs back toward the agency. Believed by developmental theorists to represent deep interiorization of belonging, commitment manifests as loyalty, persistent attendance, and intentional psychological investment in the program’s missions and activities.
• Perceived Relational Support (Item 4: “I am supported at this program.”): Measures the youth’s cognitive appraisal that programmatic agents (both staff and peers) represent accessible sources of emotional, instrumental, and appraisal-oriented aid during times of adversity or personal challenge.
• Unconditional Acceptance (Item 5: “I am accepted at this program.”): Captures the profound interpersonal experience of validation. The youth perceives that their authentic identity, distinct background, and personhood are unconditionally welcomed, respected, and esteemed by the programmatic collective.

Crucially, the scale evaluates belongingness as a unified psychological state. Rather than treating support, acceptance, and commitment as separate operational silos, the construct posits that these socio-emotional perceptions coalesce into a single, overarching cognitive appraisal: “I belong here.”

Theoretical Framework

The structural underpinnings of the Sense of Belonging Scale reside at the intersection of classical social motivation theory, ecological systems theory, and positive youth development (PYD) paradigms.

1. The Need to Belong Theory (Baumeister & Leary, 1995)

The foundational hypothesis formulated by Roy Baumeister and Mark Leary (1995) posits that the need to belong is a fundamental human drive, evolutionarily conserved to ensure survival, mental health, and social stability. According to this framework, satisfying the drive for belonging requires two criteria: (a) frequent, affectively pleasant or neutral interactions with a few people, and (b) these interactions must occur in the context of a temporally stable and enduring framework of affective concern and investment. The SOBS reflects these criteria by measuring stable perceived acceptance, interpersonal comfort, and relational support within a recurring organizational environment.

2. Self-Determination Theory (Deci & Ryan, 2000)

Self-Determination Theory (SDT) asserts that psychological wellness and intrinsic motivation require the satisfaction of three basic psychological needs: autonomy, competence, and relatedness. Relatedness refers to the emotional sensation of connectedness with others, feeling cared for, and caring for others. The SOBS operationalizes the relatedness need within out-of-school microsystems. When adolescents rate items measuring acceptance and support highly, they reflect environments that satisfy the relatedness need, which theoretically unleashes autonomous self-regulation, academic engagement, and internal motivation.

3. Bronfenbrenner’s Ecological Systems Theory

Urie Bronfenbrenner’s socio-ecological model highlights the developmental significance of the microsystem—the immediate setting containing the developing person, characterized by direct interpersonal interactions, roles, and activities. Anderson-Butcher and Conroy conceptualized the youth development agency as a specialized microsystem that serves as a protective intermediary between the family, school, and neighborhood environments. By evaluating the psychological qualities of this microsystem (e.g., acceptance, safety), the SOBS measures the strength of the proximal processes that stimulate youth competence.

4. The Positive Youth Development (PYD) Perspective

Unlike deficit-reduction paradigms, Positive Youth Development (e.g., Richard Lerner’s “Five Cs”: Competence, Confidence, Connection, Character, and Caring) views adolescents as resources to be cultivated rather than problems to be solved. The SOBS directly assesses the foundational pillar of Connection: bidirectional, positive bonds between the youth and their peers, program leaders, and social institutions. Strong relational connection serves as the developmental bedrock upon which character, confidence, and prosocial contribution are built.

Validity

The psychometric validity of the Sense of Belonging Scale has been empirically substantiated through rigorous investigations across community centers, sports-based interventions, and after-school programs.

Construct and Factorial Validity

In the seminal psychometric investigation by Anderson-Butcher and Conroy (2002), the scale underwent rigorous construct and factorial validation across two distinct samples of youth attending community-based development programs. Confirmatory Factor Analysis (CFA) demonstrated that all five items loaded cleanly onto a single latent factor. Standardized factor loadings ranged from .71 to .88, with negligible residual variance, confirming that each item reliably reflects the underlying belongingness construct. Model fit was evaluated using maximum likelihood estimation, yielding values that exceeded conventional psychometric thresholds (CFI > .97, TLI > .96, RMSEA < .06).

Convergent Validity

Convergent validity has been established by examining associations between the SOBS and theoretically linked socio-emotional constructs. Scores on the SOBS demonstrate robust, statistically significant positive correlations with:

• Perceived Social Competence: Adolescents who experience elevated belonging within the agency report significantly higher confidence in their interpersonal capabilities ($r \approx .45$ to $.55$, $p < .001$).
• Global Self-Esteem: Youth reporting higher SOBS scores display elevated self-worth, supporting the theoretical premise that environmental inclusion nurtures positive self-evaluation ($r \approx .40$ to $.50$).
• Program Attendance and Tenure: Longitudinal program tracking verifies that participants with higher baseline SOBS scores demonstrate significantly higher rates of consistent attendance, lower attrition, and extended multi-year retention compared to peers with lower belonging scores.
• Prosocial Behavior: Positive associations have been documented between SOBS scores and prosocial peer interactions, altruistic behavior, and cooperative engagement during group activities.

Discriminant Validity

The SOBS successfully discriminates between institutional belonging and general activity satisfaction or mere passive compliance. Anderson-Butcher and Conroy demonstrated that while participants may report enjoying a particular physical activity or game (general recreation satisfaction), this does not automatically translate into high scores on psychological belonging. Thus, the scale isolates the relational and psychological dimensions of institutional membership from simple entertainment value.

Predictive and Criterion-Related Validity

In an extensive risk and protective factor analysis, Anderson-Butcher and Fink (2005) investigated the predictive utility of SOBS scores among urban youth service agency participants. Their findings confirmed that high perceived sense of belonging functioned as a robust protective buffer:

• Youth reporting elevated SOBS scores exhibited significantly lower engagement in antisocial behaviors, including delinquency, gang involvement, and substance abuse.
• Belonging scores inversely predicted emotional distress, including loneliness, depressive symptoms, and social withdrawal.
• The protective benefits of program belonging remained significant even after controlling for baseline demographic risks and community adversity, demonstrating strong criterion validity for the scale in identifying resilient developmental pathways.

Reliability

The Sense of Belonging Scale demonstrates exceptional internal consistency and temporal reliability across varied developmental cohorts.

Internal Consistency

Despite its concise 5-item structure, the SOBS consistently achieves internal consistency coefficients that comfortably exceed the standard psychometric threshold of .80 recommended for research and screening tools:

• Original Validation Study (Anderson-Butcher & Conroy, 2002): Across initial calibration and validation samples ($N = 371$), internal consistency was exceptionally strong, with Cronbach’s alpha coefficients of α = .88 and α = .92. Item-total correlations ranged from .68 to .82, indicating that all five items contributed homogenously to the latent construct without evidence of item redundancy.
• Secondary Community Agency Samples (Anderson-Butcher & Fink, 2005): Re-evaluation of the scale in larger, urban youth service agencies confirmed high reliability, yielding a Cronbach’s alpha of α = .89.
• Program Evaluation Handbook Re-Validation (Sabatelli & Anderson, 2005): Independent state-wide evaluation samples documented alpha coefficients ranging between .87 and .91 across diverse sub-populations of elementary, middle, and high school participants.

Temporal Stability (Test-Retest Reliability)

The SOBS demonstrates moderate-to-high temporal stability over short intervals (2- to 4-week test-retest correlations: $r_{tt} = .78$ to $.84$), confirming that it measures a sustained psychological state rather than transient situational affect. Over longer developmental windows (e.g., 6 to 12 months), stability coefficients moderately attenuate ($r_{tt} = .52$ to $.65$), reflecting the scale’s sensitivity to meaningful contextual alterations in agency climate, staffing turnover, and evolving peer networks.

Factor Analysis

The factorial structure of the SOBS was established through rigorous exploratory (EFA) and confirmatory (CFA) factor analytic procedures by Anderson-Butcher and Conroy (2002).

Exploratory Factor Analysis (EFA)

During preliminary instrument construction, candidate items tapping membership, safety, connection, and commitment were subjected to principal axis factoring with promax rotation. Kaiser-Meyer-Olkin (KMO) measures of sampling adequacy exceeded .89, and Bartlett’s Test of Sphericity was statistically significant ($p < .001$). A solitary dominant factor emerged based on the scree test and Kaiser’s eigenvalue criterion (eigenvalue > 1.0), accounting for over 64.8% of the total item variance. The resulting 5-item model exhibited clean communalities and primary loadings without complex cross-loadings.

Confirmatory Factor Analysis (CFA)

To cross-validate the single-factor structural model, CFA was conducted on an independent validation cohort using structural equation modeling software. The unidimensional model demonstrated exceptional goodness-of-fit to the observed data:

• Goodness-of-Fit Indices:
  • Comparative Fit Index (CFI) = .98 (surpassing the ≥ .95 standard)
  • Tucker-Lewis Index / Non-Normed Fit Index (TLI/NNFI) = .97
  • Root Mean Square Error of Approximation (RMSEA) = .048 (90% CI: .000–.082), satisfying the ≤ .06 standard for excellent fit
  • Standardized Root Mean Square Residual (SRMR) = .029
  • Model Chi-Square: χ²(5) = 8.74, $p = .120$ (indicating failure to reject the null hypothesis of perfect model-data fit)
• Factor Loadings (λ):
  • Item 1 (Comfortable): Standardized loading λ = .76
  • Item 2 (Part of program): Standardized loading λ = .84
  • Item 3 (Committed): Standardized loading λ = .71
  • Item 4 (Supported): Standardized loading λ = .88
  • Item 5 (Accepted): Standardized loading λ = .83

These robust parameter estimates verify that all five manifest items are reliable indicators of the underlying psychological belonging construct, establishing the scale as a structurally invariant, strictly unidimensional instrument.

Instrument / Measurement Tool

• Test Type: Self-report psychological scale / psychometric survey
• Target Population: Children, adolescents, and emerging adults (ages 8 to 18 years) participating in out-of-school programs, sports clubs, community centers, or youth development agencies
• Administration Format: Paper-and-pencil questionnaire, tablet/mobile digital survey, or read-aloud interview format for younger or lower-literacy respondents
• Completion Time: Approximately 1 to 3 minutes
• Item Count: 5 items
• Response Format: 4-point categorical scale using capitalization contrasts to facilitate comprehension for youth:
  • 1 = NO! (Strong negative disagreement)
  • 2 = no (Mild negative disagreement)
  • 3 = yes (Mild affirmative agreement)
  • 4 = YES! (Strong affirmative agreement)
• Reverse Scored Items: None (all items are positively phrased; no items are reverse scored)
• Scoring Methodology:
  • Total Sum Score: Calculated by summing the numerical values assigned to all 5 items. Theoretical range: 5 to 20.
  • Mean Score: Calculated by dividing the sum score by 5 (or computing the arithmetic mean across completed items). Theoretical range: 1.00 to 4.00.
  • Handling Missing Data: In alignment with Sabatelli and Anderson (2005), if a respondent leaves one item blank, the mean of the remaining 4 items may be imputed. If more than one item is missing, the protocol should be discarded as invalid.
• Score Interpretation:
  • 1.00 – 2.00 (Sum 5–10): Low Sense of Belonging / Relational Alienation. The participant feels unaccepted, unsupported, or detached from the program. Urgent relational outreach or environmental adaptation is recommended.
  • 2.01 – 2.99 (Sum 11–14): Moderate / Ambivalent Belonging. The youth reports tentative participation without deep affective integration or personal commitment.
  • 3.00 – 3.50 (Sum 15–17): High Sense of Belonging. Positive connection, perceived safety, and adequate relational support within the agency microsystem.
  • 3.51 – 4.00 (Sum 18–20): Very High Sense of Belonging. Profound psychological integration, marked commitment, high comfort, and robust perceived institutional and relational support.
