Self-Reported Participant Role Scale

1. Abstract

The Self-Reported Participant Role Scale (SPRS; Pozzoli & Gini, 2010; Pozzoli, Gini, & Vieno, 2012) is a specialized psychometric assessment instrument designed to capture the multifaceted social dynamics of school bullying from a systemic participant role perspective. Grounded in Salmivalli and colleagues’ social-ecological framework, the instrument departs from traditional peer-nomination methods by providing a standardized, brief, self-report inventory that measures four distinct behavioural orientations within the peer group ecology: Bullying perpetration, active Defending of victims, Passive Bystanding, and peer Victimization. The questionnaire comprises 12 items systematically structured across these four latent dimensions (3 items per subscale), capturing physical, verbal, and indirect/relational forms of peer aggression, bystander apathy, and supportive intervention. Items are rated on a 4-point Likert-type frequency metric ranging from 1 (“Never”) to 4 (“Almost Always”). Psychometric evaluations across multiple adolescent and middle-school cohorts have demonstrated robust structural validity through confirmatory factor analysis, confirming a four-factor correlated model with excellent fit indices (e.g., CFI ≥ .95, RMSEA ≤ .05). Composite reliability (CR) indices indicate acceptable to high internal consistency across subscales: Bullying (CR = .76), Defending (CR = .75), and Passive Bystanding (CR = .76), alongside Cronbach’s alpha coefficients ranging from .62 to .81 across international adaptation studies (Kane, 2015; Pozzoli & Gini, 2010). The SPRS has proven invaluable in school psychology, educational sociology, and developmental criminology, illuminating the interaction between individual social-cognitive variables (e.g., moral disengagement, empathic responsiveness, personal responsibility) and classroom contextual norms. This article provides an extensive psychometric and theoretical review of the SPRS, detailing its factorial architecture, reliability metrics, empirical validity, administration guidelines, and research applications.

4. Purpose

School-based bullying is fundamentally a complex group phenomenon rather than merely an isolated, dyadic interaction between an aggressive perpetrator and an unfortunate target. For decades, peer-nomination techniques (e.g., the original Participant Role Questionnaire developed by Christina Salmivalli and colleagues) served as the primary empirical standard for operationalizing youth peer roles. However, peer-nomination sociometric inventories often present significant ethical, logistical, and computational challenges. They require whole-classroom participation rates typically exceeding 80% to maintain network stability, involve complex sociometric roster calculations, and can trigger parental or institutional concern regarding the explicit peer-labeling of children. The Self-Reported Participant Role Scale (SPRS) was developed to address these methodological barriers by offering an efficient, psychometrically sound, self-administered diagnostic and research tool.

The primary purpose of the SPRS is to systematically quantify self-perceived participation in peer aggression across the four central archetypes of the peer group: bullying others, actively intervening to protect victimized peers, remaining passively detached as a bystander, and experiencing peer-directed victimization. By capturing each dimension through parallel manifestations of aggression—specifically physical assault, verbal degradation, and relational/indirect ostracism—the scale provides a comprehensive behavioral snapshot of an individual adolescent’s involvement in peer victimization dynamics.

In research contexts, the SPRS enables scholars to run sophisticated statistical models, such as multilevel structural equation modeling (MSEM) and latent class analysis (LCA), to investigate how individual-level psychological traits interact with classroom-level ecological properties. Clinically and pedagogically, the SPRS serves as a vital diagnostic screen for school psychologists, counselors, and anti-bullying program coordinators. It allows practitioners to assess baseline rates of defender behaviors versus bystander apathy prior to implementing targeted systemic interventions (such as the KiVa antibullying program or Positive Behavioral Interventions and Supports [PBIS]), measure changes over time, and evaluate the specific behavioral pathways that lead youth to transition from passive bystanders to active defenders.

5. Psychological Construct

The SPRS operationalizes four core behavioral dimensions that define peer interactions when bullying incidents unfold within school environments. Rather than categorizing students into mutually exclusive social types, the instrument conceptualizes participant roles as continuous behavioral dimensions along which any given adolescent may demonstrate varying degrees of involvement.

Bullying Perpetration

Bullying perpetration is defined as repeated, intentional, unprovoked aggressive acts characterized by an observed or perceived power imbalance between the perpetrator and the target. The SPRS measures this dimension across three distinct phenotypic expressions:

• Physical Aggression: Engaging in bodily violence, shoving, or striking classmates (e.g., Item 1: “I hit or push some of my classmates”).
• Verbal Aggression: Inflicting psychological harm through insults, derisive name-calling, and verbal intimidation (e.g., Item 2: “I offend or give nasty nicknames to some of my classmates”).
• Relational / Indirect Aggression: Manipulating social status, intentionally excluding peers from peer activities, and covertly damaging reputations through gossip (e.g., Item 3: “I exclude some classmates from the group and I spread rumours about them when they don’t hear”).

Active Defending

Active defending represents prosocial, courageous intervention oriented toward alleviating the distress of the victim and confronting aggressive behavior. Defending carries significant social risk, as defenders openly challenge the power hierarchy established by bullies. The SPRS models defending through direct physical or verbal confrontation as well as restorative interpersonal support:

• Direct Physical Intervention: Interceding physically or verbally to halt acute attacks against victimized peers (e.g., Item 4: “I defend the classmates who are hit or attacked hard”).
• Consolatory / Relational Support: Offering comfort, peer inclusion, and emotional validation to socially alienated classmates (e.g., Item 5: “I try to help or comfort classmates who are isolated or excluded from the group”).
• Authoritative Confrontation: Actively demanding the cessation of verbal harassment or intimidation directed at vulnerable peers (e.g., Item 6: “If someone teases or threatens a classmate I try to stop him/her”).

Passive Bystanding

Passive bystanding describes non-intervention, behavioral disengagement, and quiet witness status during peer victimization episodes. While passive bystanders do not actively execute aggressive acts, their silence serves as implicit social reinforcement, validating the bully’s perceived power and signaling to the victim that no peer support is forthcoming:

• Detached Inaction: Deliberately refusing to intervene or get involved during violent incidents (e.g., Item 7: “If a classmate is hit or threatened, I do nothing and I don’t meddle”).
• Physical Avoidance and Non-interference: Standing by as an idle observer while deliberately minding one’s own business (e.g., Item 8: “When a classmate is hit or pushed I stand by and mind my own business”).
• Cognitive and Social Disregard: Feigning ignorance or normalizing the covert relational exclusion of peers (e.g., Item 9: “If I know that someone is excluded or isolated from the group I act as if nothing has happened”).

Peer Victimization

Peer victimization reflects the subjective experience of being the repeated target of unprovoked aggressive acts perpetrated by stronger or more dominant peers. The SPRS mirrors the bullying subscale by assessing the three primary forms of victimization:

• Physical Victimization: Being the recipient of severe physical attacks, blows, or shoves (e.g., Item 10: “I am attacked hard hit or pushed by some classmates”).
• Verbal Victimization: Suffering verbal abuse, derisive teasing, and targeted humiliation (e.g., Item 11: “Some classmates give me nasty nicknames or offend me”).
• Relational Victimization: Experiencing intentional social exclusion and systematic character defamation through malicious gossip (e.g., Item 12: “I know that someone spreads nasty rumours about me when I can’t hear”).

6. Theoretical Framework

The conceptual foundation of the SPRS integrates three foundational psychological paradigms: the Participant Role Model of school bullying, Albert Bandura’s Social Cognitive Theory of Moral Agency, and Bronfenbrenner’s Social-Ecological Systems Theory.

The Participant Role Model

Pioneered by Christina Salmivalli and colleagues (1996), the Participant Role Model revolutionized bullying research by reconceptualizing bullying from an individual behavioral pathology into a systemic social event. In any given bullying episode, the peer audience is rarely neutral; peers divide into specialized functional roles: the ringleader bully who initiates aggression, the assistants who actively join in, the reinforcers who laugh and encourage the perpetrator, the outsiders / passive bystanders who observe without acting, and the defenders who actively comfort or protect the target. Pozzoli, Gini, and Vieno (2012) refined this model for brief self-report measurement by condensing these archetypes into the four most theoretically distinct and behaviorally unambiguous constructs: perpetrators, defenders, passive bystanders, and victims.

Social Cognitive Theory and Moral Disengagement

Bandura’s (1991, 1999) theory of moral disengagement serves as a key explanatory mechanism for the divergent pathways captured by the SPRS. When individuals witness or engage in interpersonal cruelty, self-regulatory moral sanctions are typically activated, generating guilt or distress unless disengaged. Bullies extensively deploy moral disengagement mechanisms (e.g., moral justification, euphemistic labeling, displacement of responsibility, and dehumanization of the victim) to inflict harm without self-condemnation. In contrast, passive bystanders frequently rely on diffusion of responsibility (“Others are watching, so it is not my job to intervene”) and attribution of blame to justify their inertia. Defenders, on the other hand, possess robust moral agency, characterized by heightened moral responsibility, advanced emotional empathy, and high self-efficacy for intervention (Pozzoli & Gini, 2010).

Social-Ecological and Normative Theory

Grounded in Bronfenbrenner’s ecological systems theory, the SPRS was developed specifically to evaluate how classroom-level descriptive and injunctive norms moderate personal moral attitudes (Pozzoli, Gini, & Vieno, 2012). Classrooms function as microsystems with emergent social norms. In classrooms where peer norms strongly favor defending, students with moderate individual empathy are significantly more likely to translate empathetic feelings into active defending behaviors. Conversely, in classrooms where pro-bullying or apathetic bystander norms prevail, the social cost of defending escalates, steering students toward self-protective passive bystanding.

7. Validity

The structural, convergent, discriminant, and criterion validity of the SPRS has been empirically confirmed across multiple independent investigations involving children and adolescents in primary, middle, and secondary schools.

Construct and Structural Validity

Confirmatory factor analyses (CFA) conducted by Pozzoli and Gini (2010) and Pozzoli, Gini, and Vieno (2012) established that a four-factor correlated model perfectly reproduces empirical covariance matrices across adolescent cohorts. The four-factor structure demonstrates superior goodness-of-fit compared to competing unidimensional, two-factor (prosocial vs. antisocial), or three-factor models. Factor loadings for each item onto its hypothesized latent construct consistently exceed λ = .50, confirming strong construct representation across the physical, verbal, and relational modalities.

Convergent Validity

Convergent validity is robustly demonstrated through strong theoretical correlations with established psychometric indices:

• Active Defending: Positively correlated with affective empathy (r ≈ .35 to .48), moral responsibility for intervention (r ≈ .42 to .55), and social-emotional self-efficacy (Kane, 2015; Pozzoli & Gini, 2010).
• Bullying Perpetration: Strongly and positively correlated with mechanisms of moral disengagement (r ≈ .40 to .58), direct proactive aggression, and self-serving cognitive distortions, while exhibiting strong negative associations with empathic concern.
• Passive Bystanding: Moderately correlated with bystander moral disengagement, fear of social retaliation, perceived peer pressure to conform, and personal diffusion of responsibility (Pozzoli, Gini, & Vieno, 2012).
• Peer Victimization: Positively associated with internalizing difficulties, somatic complaints, social anxiety, and feelings of peer rejection.

Discriminant Validity

Discriminant validity is supported by the distinct factor correlations observed between subscales. Although bullying and defending represent opposing behavioral choices within the peer ecology, their latent correlation is consistently negative or orthogonal, demonstrating that the items cleanly differentiate aggressive dominance from prosocial intervention. Furthermore, passive bystanding correlates only moderately with defending (typically negative, r ≈ -.20 to -.35), confirming that passive inaction is an independent behavioral stance rather than simply the total absence of prosocial competence.

8. Reliability

The internal consistency and measurement precision of the SPRS have been established using both classical test theory (Cronbach’s alpha) and structural equation modeling metrics (Composite Reliability, ω / CR).

Composite Reliability

In the foundational psychometric validation studies conducted by Pozzoli and Gini (2010), composite reliability indices were computed across the subscales to evaluate latent internal consistency while accounting for specific item factor loadings:

• Bullying Subscale: Composite Reliability (CR) = 0.76
• Active Defending Subscale: Composite Reliability (CR) = 0.75
• Passive Bystanding Subscale: Composite Reliability (CR) = 0.76

These values demonstrate solid reliability, well above the standard .70 psychometric threshold, particularly notable given that each subscale consists of an ultra-brief, three-item configuration designed to maximize administration efficiency.

Internal Consistency (Cronbach’s Alpha) Across Independent Cohorts

Subsequent psychometric evaluations across diverse samples have substantiated the scale’s reliability. In an independent validation study investigating adolescent participant roles, empathy, and personal responsibility, Kane (2015) documented the following Cronbach’s alpha coefficients across all four subscales:

• Active Defender Subscale: α = .81 (indicating high internal consistency)
• Passive Bystander Subscale: α = .67
• Peer Victim Subscale: α = .67
• Bully Subscale: α = .62

The slightly lower Cronbach’s alpha for the bully subscale (α = .62) is common in non-clinical adolescent self-report samples due to positive skewness and social desirability bias inherent in admitting to aggressive acts, as well as the deliberate breadth of the three items (which sample three distinct modalities: physical, verbal, and indirect bullying). In contrast, structural equation modeling frameworks (e.g., Pozzoli et al., 2012) establish that composite reliabilities consistently exceed .75 when measurement error is appropriately modeled.

9. Factor Analysis

The latent architecture of the SPRS has been scrutinized through exploratory (EFA) and confirmatory factor analysis (CFA) across multiple large-scale developmental samples.

Factor Architecture

The instrument is parameterized as a four-factor oblique measurement model comprising twelve observed indicators:

• Factor 1: Bullying Perpetration (Items 1, 2, 3)
• Factor 2: Active Defending (Items 4, 5, 6)
• Factor 3: Passive Bystanding (Items 7, 8, 9)
• Factor 4: Peer Victimization (Items 10, 11, 12)

Model Fit and Confirmatory Parameters

In structural equation modeling analyses reported by Pozzoli and Gini (2010) and Pozzoli, Gini, and Vieno (2012), CFA was conducted using maximum likelihood estimation with robust standard errors (MLR) to account for multivariate non-normality. The four-factor correlated model exhibited excellent fit to empirical data:

• Comparative Fit Index (CFI) ≥ .95
• Tucker-Lewis Index (TLI) ≥ .94
• Root Mean Square Error of Approximation (RMSEA) ≤ .048 (90% CI [.038, .058])
• Standardized Root Mean Square Residual (SRMR) ≤ .042

Standardized factor loadings across all items were statistically significant (p < .001). Items loading onto Defending exhibited loadings ranging from .68 to .82; items loading onto Passive Bystanding exhibited loadings from .65 to .78; and items loading onto Bullying and Victimization exhibited loadings from .58 to .76. Inter-factor correlations revealed that Bullying and Victimization share a low-to-moderate positive correlation, consistent with the documented existence of “bully-victims,” whereas Defending correlated negatively with both Bullying and Passive Bystanding.
