The Reactive–Proactive Aggression Questionnaire: Measurement Invariance and Reliability Among a School Sample of Portuguese Youths

Aggression is an important risk factor for various forms of problem behaviors in adolescence, and research has often distinguished between reactive and proactive forms of aggression. The aim of the present study was to compare the psychometric properties (i.e., structural invariance, internal consistency, and criterion validity) of the Reactive–Proactive Aggression Questionnaire (RPQ) between males and females among a mixed-gender school sample of 782 Portuguese youth (M?=?15.87 years, SD?=?1.72). Confirmatory factor analysis revealed that a two-factor first-order structure obtained the best fit and cross-gender measurement invariance was demonstrated after excluding item 21. The Portuguese version of the RPQ demonstrated generally adequate psychometric properties of internal consistency measured by Cronbach’s alpha and omega coefficient, convergent validity, discriminant validity, criterion-related validity, and known-groups validity. Findings are discussed in terms of the use of the RPQ with male and female youths.     

The Peer Aggressive and Reactive Behavior Questionnaire (Parb-Q): Measurement Invariance Across Italian and Brazilian Children, Gender and Age

This study examines measurement invariance, reliability and scores differences of the Peer Aggressive and Reactive Behaviors Questionnaire (PARB-Q) across Italian and Brazilian children, gender and age. Participants were 587 Italian and 727 Brazilian children, aged 7–13 years from 12 elementary schools. The PARB-Q is a brief self-report instrument composed by two scales that assess aggressive behavior and reactions to peer aggression. Multigroup confirmatory factor analyses indicated full measurement invariance of the PARB-Q across groups based on country, gender and age, providing support for the unidimensionality of the first scale (direct peer aggression, PA) and a 3-factor model of the second scale (reactive aggression, RA; seeking teacher support, STS; internalizing reaction, IR). Reliability indices were good for all factors. Italian children reported a higher frequency of PA and a lower frequency of IR than the Brazilian children. Boys scored higher than girls on PA and RA, while girls scored higher than boys on STS and IR. Younger children reported a lower frequency of PA and a higher frequency of STS than older children. Results provide support for structure validity and reliability of the PARB-Q in two countries and information on differences related to gender, age and culture in peer relationships in elementary school.     

Further Validation of a Measure of Proactive and Reactive Aggression Within a Clinical Child Population

The current study provided further validity for the use of a measure of proactive and reactive aggression that was first developed by Little and his colleagues. Confirmatory factor analyses performed with a high-risk clinical population (N = 107) revealed that the model was a good fit to the data. Structural equation models revealed significant associations in the expected direction between the Little et al. measure and another measure of proactive and reactive aggression developed by Dodge and Coie. Further analyses revealed that the proactive aggression subscales of the Little et al. and Dodge and Coie measures were significantly related to conduct problems. However, the reactive aggression subscale of the Little et al. measure was not related to social problems while both the proactive and reactive aggression subscales of the Dodge and Coie measure were.     

Screening symptoms of reactive attachment disorder: evidence for measurement invariance and convergent validity

The Relationship Problems Questionnaire (RPQ) was developed to screen symptoms of the inhibited and disinhibited subtype of reactive attachment disorder (RAD). This study further examines the psychometric properties of the RPQ in children with severe emotional and behavioural problems by testing its measurement invariance across informants and its convergent validity. Parents and teachers of 152 children [mean age (M_age) = 7.92] from 20 schools for special education filled out the RPQ and the Strengths and Difficulties Questionnaire (SDQ). During a home visit in a subsample of 77 children the Disturbances of Attachment Interview (DAI) was administered to the caregiver and the child was observed using an observational schedule for RAD. Exploratory and confirmatory factor analyses revealed the expected two‐factor structure for both parent and teacher RPQ. Configural and metric invariance, but no scalar invariance, were obtained across informants. Both RPQ‐subscales had acceptable to good internal consistencies and correlated as expected with similar DAI‐subscales. Furthermore, the disinhibited RPQ‐scale related with observations of the child's approach to a stranger. Finally, significant associations were found between the RPQ and the SDQ. Overall, the RPQ has good psychometric qualities as a multi‐informant instrument for RAD‐symptoms in children with severe emotional and behavioural problems.

Violent media exposure,aggression and CU traits in adolescence: Testing the selection and socialization hypotheses

We investigated the role of exposure to violent action for later aggression and for later callous-unemotional traits in a sample of Swedish adolescents (N = 77–85), testing the selection and socialization hypotheses. Adolescents reported on violent delinquency and on callous-unemotional (CU) traits at age 15, on their media habits at age 16 and on reactive and proactive aggression and CU traits at age 18. The socialization hypothesis was supported with regard to aggression, that is, violent delinquency did not affect consumption of violent action, but controlling for violent delinquency, consumption of violent action added to proactive aggression and, marginally, to reactive aggression. The selection hypothesis was supported with regard to CU traits, that is, high levels of CU traits predicted frequent consumption of violent action, but consumption of violent action did not affect later levels of CU traits. Frequent violent media use was associated with later aggression. The associations between CU traits and violent media need further study.     

Peer victimization partially mediates the schizotypy-aggression relationship in children and adolescents

While persuasive evidence has accumulated over the past 15 years documenting an association between schizophrenia and violence, there are 3 unresolved issues. First, does a downward extension of this relationship exist at the nonclinical level with respect to schizotypal personality and aggression in children? Second, is aggression more associated with impulsive reactive aggression or with more planned proactive aggression. Third and importantly, does peer victimization mediate the relationship between schizotypy and aggression? A further aim of this cross-sectional study was to examine the utility of a new child self-report measure of schizotypal personality. These issues were examined in a sample of 3804 schoolchildren assessed on schizotypy using the Schizotypal Personality Questionnaire-Child (SPQ-C), reactive-proactive aggression, and peer victimization. A confirmatory factor analysis confirmed the 3-factor structure (cognitive-perceptual, interpersonal, and disorganized) of the SPQ-C. Schizotypy was positively associated with total aggression and reactive aggression but not with proactive aggression. Peer victimization was found to significantly mediate the schizotypy-aggression relationship, accounting for 58.9% of the association. Results are broadly consistent with the hypothesis that schizotypal features elicit victimization from other children, which in turn predisposes to reactive retaliatory aggression. Findings are to the authors’ knowledge the first to document any mediator of the schizotypy-aggression relationship and have potential treatment implications for violence reduction in schizophrenia-spectrum disorders. This study also provides initial evidence for the factorial and discriminant validity of a brief and simple measure of schizotypal personality in children as young as 8 years.     

A parent questionnaire for distinguishing between reactive and proactive aggression in children

Abstract Background Evidence suggests that reactive and proactive aggression can be distinguished on the basis of teacher-rating scales. In this article a newly developed parent-rated questionnaire that aims to distinguish between reactive and proactive aggression is evaluated with regard to its structure and validity. Method In study 1, a confirmatory factor analysis was performed on the data of 442 children aged 6–12 years of a general population. Study 2 examined the relations between the two forms of aggression and hostile intentions, expected outcome of aggression, ADHD symptoms and callous-unemotional traits in a sample of 40 normal and 40 disruptive behaviour disordered boys aged 8–12 years. Results The confirmatory factor analysis showed that the two-factor model, unlike a singlefactor model, produced a reasonable fit to the data. The results of study 2 showed that the correlations between the different variables and reactive aggression differed from the correlations with proactive aggression in ways that were consistent with theoretical definitions and earlier findings. Conclusion These results, in addition to those of earlier studies using teacher-rating scales, suggest that it is possible to make a valid distinction between reactive and proactive aggression using this newly developed parent-rated questionnaire.     

Gender differences in reactive and proactive aggression

The purpose of our investigation was to study gender differences in proactive and reactive aggression in a sample of 323 clinically referred children and adolescents (68 females and 255 males). Proactive aggression and reactive aggression were assessed using the Proactive/Reactive Aggression Scale. Demographic, historical, family, diagnostic, and treatment variables were entered into stepwise regression analyses to determine correlates of proactive and reactive aggression in males and females. Results reveal high rates of aggression in both males and females in the sample. Self reported drug use, expressed hostility, and experiences of maladaptive parenting were correlated with proactive aggression for both genders. Hyperactive/impulsive behaviors were correlated with male reactive aggression. An early age of traumatic stress and a low verbal IQ were correlated with female proactive aggression. Gender differences in correlates of proactive and reactive aggression may provide possible targets for research, prevention, and treatment efforts focused on reducing maladaptive aggression in clinically referred youth.     

Self-Reported Time in Bed and Sleep Quality in Association with Internalizing and Externalizing Symptoms in School-Age Youth

This study investigated the relationship between self-reported time in bed and sleep quality in association with self-reported internalizing and externalizing symptoms in a sample of 285 elementary school students (52 % female) recruited from a rural Midwestern elementary school. Path models were used to estimate proposed associations, controlling for grade level and gender. Curvilinear associations were found between time in bed and anxiety, depressive symptoms, and irritability. Marginal curvilinear trends were found between time in bed and emotion dysregulation, reactive aggression, and proactive aggression. Sleep quality was negatively associated with anxiety, depressive symptoms, irritability, reactive aggression, and delinquency engagement. Gender and grade differences were found across models. Findings suggest that examining self-reported time in bed (both linear and quadratic) and sleep quality is important for understanding internalizing and externalizing symptoms associated with sleep in school-age youth. Incorporating self-reported sleep assessments into clinical practice and school-based evaluations may have implications for a child’s adjustment.     

Students’ and teachers’ perceptions of aggressive behaviour in adolescents with intellectual disability and typically developing adolescents

This study investigated aggressive behaviour in Serbian adolescents with intellectual disability (ID) compared to typically developing peers. The sample consisted of both male and female adolescents aged 12–18 years. One hundred of the adolescents had ID, and 348 adolescents did not have ID. The adolescents were asked to complete the Reactive-Proactive Aggression Questionnaire (RPQ), and their teachers provided ratings of aggression for the adolescents using the Children's Scale of Hostility and Aggression: Reactive-Proactive (C-SHARP). Results indicated that adolescents reported a higher prevalence of aggressive behaviour than their teachers. Reactive aggression was more prevalent than proactive aggression in both subsamples. In the subsample of adolescents with ID, there were no sex or age differences for aggression. However, in the normative subsample, boys and older adolescents scored significantly higher on aggression. According to adolescent self-reports the prevalence of aggression was higher in adolescents without ID, while teachers perceived aggressive behaviour to be more prevalent in adolescents with ID. Scientific and practical implications are discussed.     

Development of the Children's Scale of Hostility and Aggression: Reactive/Proactive (C-SHARP)

Whereas some scales exist for assessing aggression in typically developing children, they do not give a detailed analysis, and none is available for populations with developmental disabilities (DD). Parents of 365 children with DD completed the Children's Scale of Hostility and Aggression: Reactive/Proactive (C-SHARP), which surveys the severity of aggressive and hostile behaviors (Problem Scale) in addition to their proactive or reactive qualities (the Provocation Scale). Factor analysis yielded a 5-factor solution: I. Verbal Aggression (12 items), II. Bullying (12 items), III. Covert Aggression (11 items), IV. Hostility (9 items), and V. Physical Aggression (8 items). Coefficient alpha ranged from moderate (0.74, Physical Aggression) to high (0.92, Verbal Aggression). General validity was supported by expected differences between age and gender groups. Preliminary normative data were presented. The C-SHARP appears to be a promising tool for assessing aggression and hostility in children with DD.     

Moderating Effects of Gender on Outcomes Associated with Stressful Life Events Among Elementary School-Age Youth

Stressful life events have been associated with child and adolescent maladjustment, including elevated levels of aggression and anxiety (Attar et al. in J Clin Child Psychol 23:391–400, 1994; Fox et al. in J Adolesc 33:43–54, 2010). However, gender specific outcomes associated with stressful life events among elementary school-age youth are less known. Accordingly, the current study examined the role of gender in the associations between stressful life events and anxiety and proactive and reactive aggression. Participants included 294 elementary school-age children (M = 8.71, SD = 1.17, 50.7 % male). Regression analyses indicated that stressful life events were positively associated with anxiety and reactive, but not proactive, aggression. There were no gender differences with regard to the associations with anxiety symptoms or proactive aggression. However, gender moderated the association between stressful life events and reactive aggression, such that stressful life events were only positively associated with reactive aggression for boys. Future directions and implications of this research are presented.     

Proactive and Reactive Aggression Subgroups in Typically Developing Children: The Role of Executive Functioning,Psychophysiology, and Psychopathy

This study aimed to assess whether groups of aggressive children differed on psychopathic traits, and neuropsychological and neurobiological measures of prefrontal functioning consistent with the objectives of their aggression—reactive or proactive. Including 110 typically developing children (9–11 years), a latent class analysis identified a low aggression group, a high reactive aggression group, and a mixed (high reactive and proactive) aggression group. Results show high callous–unemotional traits and low resting respiratory sinus arrhythmia increased the likelihood of children being in the mixed aggression group, when compared to the reactive and low aggression groups. However, deficits in planning and inhibitory control increased the likelihood of children being in the reactive aggression group, when compared to the mixed and low aggression groups. Executive functioning deficits did not differentiate the mixed group from the low aggression group. These findings highlight psychobiological and executive functioning differences that may explain heterogeneity in childhood aggression.     

Association of Reactive–Proactive Aggression and Anxiety Sensitivity with Internalizing and Externalizing Symptoms in Children with Attention-Deficit/Hyperactivity Disorder

This study evaluates the associations among the symptoms of anxiety, depression, and disruptive behavioral disorders (DBD) in the context of their relationships with reactive–proactive aggression and anxiety sensitivity in children with attention-deficit/hyperactivity disorder (ADHD). The sample consisted of 342 treatment-naive children with ADHD. The severity of ADHD and DBD symptoms were assessed via parent- and teacher-rated inventories. Anxiety sensitivity, reactive–proactive aggression and severity of anxiety and depression symptoms of children were evaluated by self-report inventories. According to structural equation modeling, depression and anxiety scores had a relation with the DBD scores through reactive–proactive aggression. Results also showed a negative relation of the total scores of anxiety sensitivity on DBD scores, while conduct disorder scores had a positive relation with anxiety scores. This study suggests that examining the relations of reactive–proactive aggression and anxiety sensitivity with internalizing and externalizing disorders could be useful for understanding the link among these disorders in ADHD.     

Proactive, reactive, and romantic relational aggression in adulthood: Measurement, predictive validity, gender differences, and association with Intermittent Explosive Disorder

The psychometric properties of a recently introduced adult self-report of relational aggression are presented. Specifically, the predictive utility of proactive and reactive peer-directed relational aggression, as well as romantic relational aggression, are explored in a large (N = 1387) study of adults. The measure had adequate reliability and validity and the subscales demonstrated unique predictive abilities for a number of dependent variables. In particular, reactive but not proactive relational aggression was uniquely associated with history of abuse, hostile attribution biases, and feelings of distress regarding relational provocation situations. Reactive relational aggression was also more strongly related to anger and hostility than proactive aggression. In addition, relational aggression in the context of romantic relationships was uniquely related to anger, hostility, impulsivity, history of abuse, hostile attribution biases, and emotional sensitivity to relational provocations, even when controlling for peer-directed relational aggression. Gender differences in overall levels of relational aggression were not observed; however, males were most likely to engage in peer-directed proactive and reactive relational aggression whereas females were most likely to engage in romantic relational aggression. In a second study (N = 150), relational aggression was higher in a sample of adults with Intermittent Explosive Disorder than in a sample of healthy controls or psychiatric controls. The findings highlight the importance of assessing subtypes of relational aggression in adult samples. Ways in which this measure may extend research in psychology and psychiatry are discussed.     

Development of the Adult Scale of Hostility and Aggression: Reactive-Proactive (A-SHARP)

In this study, the authors developed the Adult Scale of Hostility and Aggression Reactive-Proactive (A-SHARP). Sixty-one caregivers rated 512 individuals with intellectual and developmental disabilities on the A-SHARP. Exploratory factor analysis revealed 5 factors on the Problem Scale: (a) Verbal Aggression, (b) Physical Aggression, (c) Hostile Affect, (d) Covert Aggression, and (e) Bullying. Internal consistency was high, and intercorrelation of subscales suggested logical convergent and divergent validity. Separate scores were also derived for the Provocation Scale, which was developed to reflect motivation for the aggression (reactive vs. proactive). Analyses of demographic variables revealed 1 gender effect, several effects due to age and functional level, and no effect of ethnicity. Normative data are provided for the Problem Scale.     

Reactive and proactive aggression in children A review of theory, findings and the relevance for child and adolescent psychiatry

Abstract The clinical population of aggressive children diagnosed as having an oppositional defiant disorder (ODD) or a conduct disorder (CD) is heterogeneous, both with respect to behaviour and aetiology. Recently, the following distinction has been proposed that might further clarify this heterogeneity: reactive aggression is an aggressive response to a perceived threat or provocation, whereas proactive aggression is defined as behaviour that anticipates a reward. In this article we examine various aspects of this distinction. We will [1] examine the evidence that reactive and proactive aggression are distinct phenomena by discussing the theories underlying the distinction between the subtypes in humans and we briefly review evidence for a similar distinction in animals; [2] we critically review the literature on the measurement in children via questionnaires and behavioural observations; we then point out that the correlation observed between the subtypes is due to the fact that many children show both types of aggression; [3] we review the literature on specific characteristics of the subtypes giving attention to social information processing, peer status, biological correlates and developmental history, and demonstrate that there is some evidence to suggest that reactive and proactive aggression are distinct dimensions; [4] we discuss the relevance of the distinction between reactive and proactive aggression for child and adolescent psychiatry.     

The role of delinquency,proactive aggression,psychopathy and behavioral school engagement in reported youth gang membership

Given the robust positive association between gangs and crime, a better understanding of factors related to reported youth gang membership is critical and especially since youth in gangs are a universal concern. The present study investigated the role of delinquency, proactive aggression, psychopathy and behavioral school engagement in reported youth gang membership using a large sample of 1027 Singapore adolescents. Results from logistic regression showed that delinquency, proactive aggression, and behavioral school engagement were statistically significant risk factors for reported youth gang membership, and that psychopathy was not related to reported gang membership. Implications for prevention and intervention work with respect to youth gang membership were discussed. In particular, strengthening students' engagement with school and meaningful school-related activities and developing supportive teacher–student relationships are particularly important in working with young people with respect to prevention work. Additionally, the present study's theoretical and empirical contributions were also discussed.     

Teacher-Reported Irritable and Defiant Dimensions of Oppositional Defiant Disorder: Social,Behavioral, and Academic Correlates

Previous research suggests that the symptoms of oppositional defiant disorder (ODD) reflect both a general diagnostic construct and two distinct symptom dimensions, irritability and defiant behavior. Recent studies have found that these two symptom dimensions exhibit different patterns of correlates and outcomes (e.g., irritability linked to depressive symptoms, defiant behavior linked to conduct problems). The present study investigated common and unique correlates of the irritable and defiant dimensions of ODD symptoms in a sample of 706 school-age children (49 % female, ages 5–12) in grades K-5. Classroom teachers rated their students’ ODD symptoms, proactive and reactive aggression, relational and physical aggression and victimization, withdrawn/depressed symptoms, peer rejection, and academic performance. Multilevel regression models—controlling for grade level, gender, and shared variance between symptom dimensions and variable subtypes—showed that teacher-reported irritability and defiant behavior exhibit common correlates of physical and relational aggression, relational victimization, and peer rejection. With respect to differential correlates, irritability was uniquely associated with physical victimization and withdrawn/depressed symptoms, whereas defiant behavior was uniquely associated with proactive aggression and hyperactive–impulsive symptoms. Further, reactive aggression was more strongly linked to irritability than to defiant behavior. These findings provide further support for a multidimensional conceptualization of ODD symptoms within the school context and suggest that irritability and defiant behavior have important implications across several domains of children’s social–emotional development.     

The Brief Multidimensional Students' Life Satisfaction Scale (BMSLSS): Reliability,validity, and gender invariance in an Indian adolescent sample

This study examined the internal consistency reliability, factorial, convergent, discriminant, and predictive validity, as well as gender invariance of the Brief Multidimensional Students' Life Satisfaction Scale (BMSLSS; Seligson, Huebner, & Valois, 2003) in a sample of 445 adolescents (M_age = 16.04 years) hailing from the southernmost state of India, Kerala. The study also examined the test-retest reliability (n = 392) of the BMSLSS. The Cronbach's alpha coefficient suggested that the BMSLSS was reliable. Confirmatory factor analyses demonstrated the factorial validity of the BMSLSS. Bivariate correlational analyses provided support for the convergent, discriminant, and predictive validity of the BMSLSS. The test-retest reliability coefficient indicated the temporal stability of the BMSLSS. Finally, multi-group confirmatory factor analysis provided support for the gender invariance of the BMSLSS.
