The reactive–proactive aggression questionnaire: differential correlates of reactive and proactive aggression in adolescent boys

This study reports the development of the Reactive–Proactive Aggression Questionnaire (RPQ), and the differential correlates of these two forms of aggression. Antisocial, psychosocial and personality measures were obtained at ages 7 and 16 years in schoolboys, while the RPQ was administered to 334 of the boys at age 16 years. Confirmatory factor analysis indicated a significant fit for a two‐factor proactive–reactive model that replicated from one independent subsample to another. Proactive aggression was uniquely characterized at age 7 by initiation of fights, strong‐arm tactics, delinquency, poor school motivation, poor peer relationships, single‐parent status, psychosocial adversity, substance‐abusing parents, and hyperactivity, and at age 16 by a psychopathic personality, blunted affect, delinquency, and serious violent offending. Reactive aggression was uniquely characterized at age 16 by impulsivity, hostility, social anxiety, lack of close friends, unusual perceptual experiences, and ideas of reference. Findings confirm and extend the differential correlates of proactive–reactive aggression, and demonstrate that this brief but reliable and valid self‐report instrument can be used to assess proactive and reactive aggression in child and adolescent samples.

Psychological distress associated with domestic violence in Northern Ireland

Several studies have noted an association between domestic violence and psychological distress. However, little empirical work has examined behavioral and psychological difficulties, especially with reference to dissociation and guilt, in victims of domestic violence in Northern Ireland. In addition, childhood abuse history has tended not to be assessed in studies conducted in the Province. Using measures designed to assess behavioral and psychological difficulties that are problematic to self and/or others (that is, Brief Symptoms Inventory, General Health Questionnaire, Guilt Inventory), dissociation (that is, Dissociative Experiences Scale, Peritraumatic Dissociative Experiences Questionnaire) and trauma (that is, Traumatic Experiences Checklist), the current study assessed Northern Irish victims of domestic violence from shelter-type accommodation (N=33) and a comparison sample of women from the general population (N=33). The domestic violence group displayed significantly more psychological difficulties, including higher depression, anxiety and dissociation scores. Dissociative episodes at the time of an assault were related to higher on-going dissociative experiences. Finally, the domestic violence sample reported more emotional, physical, and sexual abuse in childhood than the comparison group. Despite the difficulty generalizing from victims of domestic violence in shelter-type accommodation to all victims of spousal abuse, the current results highlight the increased levels of psychological distress in those exposed to abuse by their partner.     

Dissociative Experiences and Vividness of Auditory Imagery

The relationship between dissociation and auditory imagery were assessed, 2 variables that sometime influence on artistic creativity. A total of 170 fine arts undergraduates (94 women and 76 men) received 2 dissociation questionnaires—the Dissociative Ability Scale (DAS), and the Dissociative Experiences Scale (DES)—and 2 auditory imagery questionnaires—the Auditory Imagery Questionnaire (AIQ) and the Clarity of Auditory Imagery Scale (CAIS). Significant differences on the auditory imagery (CAIS) have been found between individuals scoring high or low on the DES and DAS. In this study, however, significant differences were only observed on the Auditory Imagery Questionnaire (AIQ) between individuals scoring high or low on the DAS. Moreover, conflicting results have been obtained on the influence of dissociative experiences on dissociative skills in 2 auditory imagery tests. The discrepancies in the results only lead to more questions being asked than answered. Several lines of research are proposed.     

Dissociative experiences, psychopathology and adjustment, and child and adolescent maltreatment in female college students.

Thirty-three female college students who scored in the upper 15% on the Dissociative Experiences Scale (DES) were compared with 33 female students who scored below the mean on the DES on measures of psychopathology (Symptom Checklist-90), college adjustment (Student Adaptation to College Questionnaire), and child and adolescent maltreatment. Compared with controls, high-DES subjects reported more psychopathology, poorer college adjustment, and a greater extent of psychological, physical, and sexual maltreatment. On the basis of the Dissociative Disorders Interview Schedule, 2 high-DES subjects but none of the control subjects met criteria for a dissociative disorder (i.e., multiple personality and psychogenic amnesia). Despite the sensitivity of the DES, 8 subjects who scored in the upper 2% of the population on the DES failed to meet criteria for a dissociative disorder.     

Psychometric Properties of the Dissociative Subtype of PTSD Scale: Replication and Extension in a Clinical Sample of Trauma-Exposed Veterans

The addition of the dissociative subtype of posttraumatic stress disorder (PTSD) to the DSM-5 has spurred investigation of its genetic, neurobiological, and treatment response correlates. In order to reliably assess the subtype, we developed the Dissociative Subtype of PTSD Scale (DSPS; Wolf et al., 2017), a 15-item index of dissociative features. Our initial investigation of the dichotomous DSPS lifetime items in a veteran epidemiological sample demonstrated its ability to identify the subtype, supported a three-factor measurement structure, distinguished the three subscales from the normal-range trait of absorption, and demonstrated the greater contribution of derealization and depersonalization symptoms relative to other dissociative symptomatology. In this study, we replicated and extended these findings by administering self-report and interview versions of the DSPS, and assessing personality and PTSD in a sample of 209 trauma-exposed veterans (83.73% male, 57.9% with probable current PTSD). Results replicated the three-factor structure using confirmatory factor analysis of current symptom severity interview items, and the identification of the dissociative subtype (via latent profile analysis). Associations with personality supported the discriminant validity of the DSPS and suggested the subtype was marked by tendencies towards odd and unusual cognitive experiences and low positive affect. Receiver operating characteristic curves identified diagnostic cut-points on the DSPS to inform subtype classification, which differed across the interview and self-report versions. Overall, the DSPS performed well in psychometric analyses, and results support the utility of the measure in identifying this important component of posttraumatic psychopathology.     

Differential Genetic and Environmental Influences on Reactive and Proactive Aggression in Children

While significant heritability for childhood aggression has been claimed, it is not known whether there are differential genetic and environmental contributions to proactive and reactive forms of aggression in children. This study quantifies genetic and environmental contributions to these two forms of aggression in an ethnically diverse urban sample of 9–10 year old twins (N = 1219), and compares results across different informants (child self-report, mother, and teacher ratings) using the Reactive–Proactive Aggression Questionnaire (RPQ). Confirmatory factor analysis of RPQ items indicated a significant and strong fit for a two-factor proactive–reactive model which was significantly superior to a one-factor model and which replicated across gender as well as the three informant sources. Males scored significantly higher than females on both self-report reactive and proactive aggression, findings that replicated on mother and teacher versions of the RPQ. Asian–Americans scored lower than most ethnic groups on reactive aggression yet were equivalent to Caucasians on proactive aggression. African–Americans scored higher than other ethnic groups on all measures of aggression except caregiver reports. Heritable influences were found for both forms of aggression across informants, but while boys’ self-reports revealed genetic influences on proactive (50%) and reactive (38%) aggression, shared and non-shared environmental influences almost entirely accounted for girls’ self-report reactive and proactive aggression. Although genetic correlations between reactive and proactive aggression were significant across informants, there was evidence that the genetic correlation was less than unity in boys self reported aggression, indicating that genetic factors differ for proactive and reactive aggression. These findings provide the first evidence for varying genetic and environmental etiologies for reactive and proactive aggression across gender, and provide additional support for distinction between these two forms of aggression.     

Ideological Orientation and Political Transition in Hong Kong: Confidence in the Future

In the two-component model of ideological orientation, a person's ideological position is jointly influenced by attitudinal and affective components. The present study adopted this conceptual model to predict confidence in the future of Hong Kong. Questionnaire responses were collected from 395 adults (56.8% men and 43.2% women) in Hong Kong in April 1995, some 2 years before its transfer from British to Chinese control. The results show that the level of confidence in Hong Kong was related to both attitudinal and affective identification with Hong Kong and China. These findings suggest that the transfer of government may have brought to the surface a collision of the divergent political cultures of Hong Kong and mainland China, resulting in two antagonistic political orientations that predicted confidence in the future of Hong Kong.     

Lack of correspondence between the reactive proactive questionnaire and the impulsive premeditated aggression scale among forensic psychiatric outpatients

The most studied bimodal classifications of aggressive behavior are the impulsive/premeditated distinction measured with the Impulsive Premeditated Aggression Scale and the reactive/proactive distinction measured with the Reactive Proactive Questionnaire. The terms of these classifications are often used interchangeably, assuming that reactive aggression is equivalent to impulsive aggression and that proactive aggressive behavior is the same as premeditated aggression. The correspondence or discrepancy between both aggression classifications/questionnaires, however, is understudied. Therefore, the current study investigated the correspondence between the RPQ and IPAS in a sample of 161 forensic psychiatric outpatients (FPOs) with severe aggressive behavior. Correlation analysis revealed a limited correspondence between the RPQ and IPAS. Cluster analyses derived three clusters from the RPQ as well as the IPAS: these clusters did not match in 60.3% of the cases. Furthermore, the notion that the RPQ measures trait aggression whereas the IPAS assesses state aggression could not be verified. The present study indicates that aggression subtypes as measured by use of the RPQ and IPAS correspond only partially and should not be used interchangeably. Furthermore, it was suggested that RPQ focuses more on actual aggressive behavior and the IPAS more on emotions and their regulation. Future research is needed to elucidate the applicability of both questionnaires in further detail.

     

Dissociative experiences and anger proneness in late adolescent females with different attachment styles

The study examined the relationships among dissociative experiences, anger proneness, and attachment styles in late adolescent females. One hundred sixty-two college students (mean age = 17.5 years) were assessed using the Dissociative Experience Scale (DES), the State-Trait Anger Expression Inventory (STAXI), and the Adult Attachment Questionnaire (AAQ), a self-report tool for assessing attachment styles (avoidant, secure, and ambivalent-resistant) in close relationships of youths and adults. Significant correlations were obtained between DES scores (total and factorial) and STAXI scores (State Anger, Trait Anger, Anger/In, and Anger/Expression), confirming in a nonclinical sample the connection between anger proneness and dissociation described in patients with dissociative disorders. Insecure females, particularly ambivalent ones, scored higher on the DES, supporting van der Kolk's hypothesis of an inverse relationship between secure attachment and dissociative tendency. Moreover, insecurely attached females showed more anger proneness, with some differences between ambivalent and avoidant types. Further research should be conducted to examine these relationships in males, as well as to clarify the role of insecure attachment in anger management and the recourse to dissociation in late adolescence as a protective response to trauma and emotional distress.     

The underlying dimensions of DSM-5 posttraumatic stress disorder (PTSD) and their relationships with mental and somatoform dissociation,depression and anxiety among jail inmates

ABSTRACT

In this study we examined the DSM-5 factor structure of scores on the Turkish version of the posttraumatic stress disorder (PTSD) Checklist for DSM–5 (PCL-5) and predictors of PTSD caseness in a sample of male prisoners. The 7-factor hybrid model was the optimal model relative to the alternatives. Consistent with the PTSD literature in prisoners, the majority of respondents had past traumatic experiences (96.7%), a probable PTSD diagnosis (68.4%), pathological dissociation (46.8%) and somatoform dissociation (52.3%). Probable PTSD caseness was significantly associated with dissociation and depression, as well as higher levels of education and being married. Re-experiencing was strongly associated with mental and somatic dissociation; whereas dysphoric arousal was related to depression and anxiety.     

Cross-Cultural Generalizability of the Reactive–Proactive Aggression Questionnaire (RPQ)

In this study, we assessed the cross-cultural generalizability of the Reactive–Proactive Aggression Questionnaire (RPQ) and tested the hypotheses that boys show higher levels of proactive aggression with increasing age and that a two-factor (reactive–proactive) structure will be observed in an East Asian population. We administered the RPQ to 5,615 male and female 11- to 15-year-old schoolchildren. CFA demonstrated a good fit of the two-factor reactive–proactive model. Proactive aggression increased significantly with age in boys but not girls, whereas reactive aggression showed no gender difference and only a minimal age increase. Results suggest the presence of meaningful differences between these aggression subtypes and the generalizability of the RPQ in an East Asian population.     

Discriminating among diagnostic categories using the Dissociative Disorders Interview Schedule

The Dissociative Disorders Interview Schedule was administered to 1,308 subjects in eight diagnostic categories, including 296 with dissociative identity disorder. The study tested three hypotheses: (1) the Mahalanobis distance between dissociative identity disorder and each of seven other diagnostic categories would be large, (2) the closest diagnostic category to dissociative identity disorder would be dissociative disorder not otherwise specified, and (3) nondissociative diagnostic categories would be closer to each other than any one to dissociative identity disorder. All three hypotheses were confirmed by these data. The findings support the conclusion that dissociative identity disorder is a discrete category or taxon.     

Prevalence of borderline personality disorder and its clinical correlates in Chinese patients with recent deliberate self-harm

This study examined the point prevalence of Borderline Personality Disorder (BPD) and its clinical correlates in patients with recent deliberate self-harm (DSH) in Hong Kong. A representative consecutive sample (n = 160) of patients with DSH referred to Prince of Wales Hospital from April 1, 2007 to March 31, 2008 was recruited. Their BPD status was determined according to the BPD subscale of the Chinese version of Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II). The point prevalence of BPD was calculated. Subjects with and without BPD were compared in terms of demographic and clinical characteristics. Thirty out of 160 (18.8%) DSH patients were found to suffer from BPD. DSH patients with BPD were more likely to be female (p = .020), more often reported history of childhood physical (p = 0.043) and sexual abuse (p < 0.001), history of past DSH (p = 0.010), being younger at first DSH (p = 0.039), and more likely to suffer from current alcohol and substance use disorder (p = 0.043) and eating disorder (p = 0.040) than those without BPD. Being female, having history of childhood sexual abuse and current alcohol and substance use disorder were found to be independent predictors of BPD status by binary logistic regression.     

Dissociation in the laboratory: a comparison of strategies

Several methods for inducing dissociation in the laboratory were examined in a sample of 78 undergraduate students. Participants scoring high or low on the Dissociative Experiences Scale participated in three dissociation challenge conditions: (a) dot-staring task, (b) administration of pulsed photic and audio stimulation and (c) stimulus deprivation. Participants recorded their dissociative experiences both before and after each of the three challenge conditions. Across conditions, high DES participants reported significantly more dissociative sensations than low DES participants, even after controlling for pre-challenge dissociation. Moreover, regardless of DES status, pulsed photo and audio stimulation produced the greatest level of dissociative symptoms. The findings suggest that the induction of dissociative symptoms in a nonclinical sample is easily accomplished in the laboratory and that those who report more dissociative symptoms in their day-to-day life exhibit more pronounced dissociative symptoms when undergoing dissociative challenge in the laboratory. Implications for the study and treatment of dissociative symptoms are discussed.     

Disintegrated experience: the dissociative disorders revisited

We present proposed changes to the dissociative disorders section of the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders and review the concept of pathological and nonpathological dissociation, including empirical findings on the relations between trauma and dissociative phenomenology and between dissociation and hypnosis. The most important proposals include the creation of two new diagnostic entities, brief reactive dissociative disorder and transient dissociative disturbance, and the readoption of the criterion of amnesia for a multiple personality disorder diagnosis. We conclude that further work on dissociative processes will provide an important link between clinical and experimental approaches to human cognition, emotion, and personality.     

Are the interpersonal and identity disturbances in the borderline personality disorder criteria linked to the traits of affective instability and impulsivity?

This study examines the degree to which two putative biologically influenced personality traits, affective instability and impulsive aggression, are associated with some of the interpersonal and intrapsychic disturbances of borderline personality disorder (BPD) and with choice of defense mechanism. In a sample of 152 personality disorder patients, affective instability and impulsive aggression were measured. Defense mechanisms were assessed in 140 of these patients using the Defensive Style Questionnaire (DSQ). The correlations between the traits of affective instability and impulsive aggression and the eight DSM-III-R criteria for borderline personality disorder and 20 DSQ defenses were examined. Affective instability was significantly correlated with the DSM-III-R criteria of identity disturbance, chronic emptiness or boredom, inappropriate anger, suicidality, and the affective instability criteria. It also was associated with the defenses of splitting, projection, acting out, passive aggression, undoing, and autistic fantasy. Impulsive aggression was related to unstable interpersonal relationships, inappropriate anger and impulsiveness and with the defense of acting out. It was negatively correlated with the defenses of suppression and reaction formation. A number of the interpersonal and experiential disturbances and defense mechanisms that are features of BPD are associated with the traits of affective instability and impulsive aggression among patients with personality disorders.     

Childhood abuse in Chinese patients with borderline personality disorder

This study examined (1) the relative prevalence of childhood abuse and other pathological childhood experiences in China reported by outpatients with borderline personality disorder (BPD), with other personality disorders, and without personality disorders; and, (2) whether the primary predictors of BPD in North America are associated with the development of BPD in China. The childhood experiences of 203 outpatients with BPD, 109 outpatients with other personality disorders, and 70 outpatients without Axis II diagnoses were assessed with the Chinese version of the Childhood Experience of Care and Abuse Questionnaire (CECA.Q). Patients with BPD reported significantly more physical, emotional, and sexual abuse than either comparison group. Four types of childhood experiences were significant predictors of BPD: maternal neglect, paternal antipathy, sexual abuse, and maternal physical abuse. The findings suggest that maternal physical abuse is as strong a predictor of BPD in China as sexual abuse, a finding not replicated in North America.     

Malingering dissociative identity disorder: objective and projective assessment

Verification of dissociative identity disorder presents challenges given the complex nature of the illness. This study addressed the concern that this disorder can be successfully malingered on objective and projective psychological tests. 50 undergraduate women were assigned to a Malingering or a Control condition, then completed the Rorschach Inkblot Test and the Dissociative Experiences Scale II. The Malingering group were asked to simulate dissociative identity disorder; controls received instructions to answer all materials honestly. Analysis indicated that malingerers were significantly more likely to endorse dissociative experiences on the Dissociative Experiences Scale II in the range common to patients with diagnosed dissociative identity disorder. However, on the Rorschach there were no significant differences between the two groups. Results suggest that the assessment of dissociative identity disorder requires a multifaceted approach with both objective and projective assessment tools. Research is needed to assess these issues in clinical populations.     

The relationship between the youth psychopathic traits inventory and psychopathology in a U.S. community sample of male youth

The Youth Psychopathic Traits Inventory (YPI) is a self-report measure of juvenile psychopathic traits. Validity data for this measure are limited, especially for nonreferred samples. This report investigated the concurrent validity of the YPI by assessing 171 nonreferred male youth (M age = 12.96 years) with a battery of self-, parent-, and peer-report measures including the Child Behavior Checklist (CBCL), the Reactive-Proactive Aggression Questionnaire (RPQ), the Antisocial Process Screening Device (APSD), and a peer-sociometric measure of aggression. Results confirmed the expected correlations between the YPI and measures of proactive aggression, other externalizing and internalizing behavior, and parent-report psychopathic-like traits. In addition, cluster analyses of YPI scores revealed 2 groups of youth (low vs. high) who scored differently on measures of externalizing behavior. This study supports the utility of the YPI as a research tool for assessing juvenile psychopathic traits.
