Collective Narcissism and its Social Consequences

Agnieszka Golec de Zavala; Aleksandra Cichocka; Roy Eidelson; Nuwan Jayawickreme

This article introduces the concept of collective narcissism--an emotional investment in an unrealistic belief about the in groups greatness--aiming to explain how feelings about an ingroup shape a tendency to aggress against outgroups. The results of 5 studies indicate that collective, but not individual, narcissism predicts intergroup aggressiveness. Collective narcissism is related to high private and low public collective self-esteem and low implicit group esteem. It predicts perceived threat from outgroups, unwillingness to forgive outgroups, preference for military aggression over and above social dominance orientation, right-wing authoritarianism, and blind patriotism. The relationship between collective narcissism and aggressiveness is mediated by perceived threat from outgroups and perceived insult to the ingroup. In sum, the results indicate that collective narcissism is a form of high but ambivalent group esteem related to sensitivity to threats to the ingroups image and retaliatory aggression.

The hypothesis that psychometric instruments incorporating local idioms of distress predict functional impairment in a non-Western, war-affected population above and beyond translations of already established instruments was tested. Exploratory factor analysis was conducted on the War-Related Psychological and Behavioral Problems section of the Penn/RESIST/Peradeniya War Problems Questionnaire (PRPWPQ; N. Jayawickreme, Jayawickreme, Goonasekera, & Foa, 2009), a measure that incorporates local idioms of distress, using data from 197 individuals living in Northern and Eastern Sri Lanka. Three subscales--Anxiety, Depression, and Negative Perception--were identified. Regression analyses were conducted to test whether these 3 subscales better predicted functional impairment than the PTSD Symptom Scale-Self Report (PSS; Foa, Riggs, Dancu, & Rothbaum, 1993) and the Beck Depression Inventory (BDI; Beck & Steer, 1987), both widely used self-report measures of posttraumatic stress disorder and depression, respectively. Two of the 3 subscales from the PRPWPQ--Anxiety and Depression--were significantly associated with higher rates of functional impairment after controlling for age, the PSS and the BDI. After the inclusion of PRPWPQ, the PSS and the BDI did not significantly contribute to the final regression model predicting functional impairment. These findings suggest that the scores of measures with local idioms of distress have incremental validity in non-Western war-affected populations, predicting functional impairment above and beyond translations of established self-report measures that have been developed in the Western world.

Prolonged Exposure (PE) therapy is an efficacious treatment for PTSD; despite this, many clinicians do not utilize it due to concerns it could cause patient decompensation.

The aim of the current study was to investigate the extent to which individual differences in personal growth initiative (PGI) were associated with lower reports of functional impairment of daily activities among a genocide-affected population in Rwanda. PGI measures an individuals motivation to develop as a person and the extent to which he or she is active in setting goals that work toward achieving self-improvement. We found that PGI was negatively associated with functional impairment when controlling for depression, posttraumatic stress disorder, and other demographic factors. Our results suggest that PGI may constitute an important mindset for facilitating adaptive functioning in the aftermath of adversity and in the midst of psychological distress, and as such they might have practical applications for the development of intervention programs.

Distress, wellbeing and war: qualitative analyses of civilian interviews from north eastern Sri Lanka

Nuwan Jayawickreme; Eranda Jayawickreme; Michelle A. Goonasekera; Edna B. Foa

This paper outlines a methodology for the development of culturally sensitive measures of war problems (including psychological and behavioural problems) and wellbeing for use among refugees affected by the recently concluded civil war in Sri Lanka. These measures were derived from qualitative data collected from individuals living in areas affected by the civil war. The authors utilised a qualitative data analysis methodology, involving both open coding and thematic analysis. Examples of frequently coded nodes and questionnaire items that were developed from them are presented, and next steps (validation of the measures) are discussed.

The current study examined gender-specific associations between trauma cognitions, alcohol cravings and alcohol-related consequences in individuals with dually diagnosed PTSD and alcohol dependence (AD). Participants (N = 167) had entered a treatment study for concurrent PTSD and AD; baseline information was collected from participants about PTSD-related cognitions in three areas: (a) Negative Cognitions About Self, (b) Negative Cognitions About the World, and (c) Self-Blame. Information was also collected on two aspects of AD: alcohol cravings and consequences of AD. Gender differences were examined while controlling for PTSD severity. The results indicate that Negative Cognitions About Self are significantly related to alcohol cravings in men but not women, and that interpersonal consequences of AD are significantly related to Self-Blame in women but not in men. These findings suggest that for individuals with comorbid PTSD and AD, psychotherapeutic interventions that focus on reducing trauma-related cognitions are likely to reduce alcohol cravings in men and relational problems in women.

Triumphalism, fear and humiliation: The psychological legacy of Sri Lanka's civil war

Eranda Jayawickreme; Nuwan Jayawickreme; Elise Miller

The Sri Lankan governments recent victory over the Liberation Tigers of Tamil Eelam (LTTE) presents a unique opportunity to resolve the long-standing ethnic conflict in the country. However, the Tamil populations distrust of the government will not change easily. Furthermore, the Tamil diaspora located in Europe, Australia, and Canada believed that the LTTE was the only force that could protect the Tamil people from annihilation, and the wars end has left them confused and humiliated. Significant psychological hurdles – including group narcissism on the part of the majority Sinhalese, feelings of vulnerability and distrust on the part of Sri Lankan Tamils, and a sense of humiliation on the part of the Tamil diaspora – need to be surmounted in order to reach a successful reconciliation.

Race-specific associations between trauma cognitions and symptoms of alcohol dependence in individuals with comorbid PTSD and alcohol dependence

Monnica T. Williams; Nuwan Jayawickreme; Rosanna Sposato; Edna B. Foa

Posttraumatic Stress Disorder (PTSD) changes the way people think about themselves, others, and the safety of the world. These cognitions may play a role in alcohol dependence, where alcohol dependence is maintained as an attempt to manage posttraumatic anxiety. The current study examined black-white differences in various PTSD cognitions and their relationship to symptoms of alcohol dependence in a dually diagnosed sample (N=167). Analyses revealed racial differences in trauma cognitions and their impact on symptoms of alcohol dependence, suggesting that trauma cognitions are more strongly associated with adverse consequences of drinking and alcohol craving severity among African Americans than European Americans. Additional relationships between ethnic identification and trauma-related cognitions are described and theoretical and clinical implications of these findings are discussed.

Measuring Depression in a Non-Western War-Affected Displaced Population: Measurement Equivalence of the Beck Depression Inventory

Nuwan Jayawickreme; Jay Verkuilen; Eranda Jayawickreme; Kaylaliz Acosta; Edna B. Foa

Depression is commonly seen in survivors of conflict and disaster across the world. There is a dearth of research on the validity of commonly used measures of depression in these populations. Measurements of depression that are used in multiple contexts need to meet measurement equivalence, i.e., the instrument measures the same construct in the same manner across different groups. The Beck Depression Inventory (BDI) was administered to female trauma survivors in the United States (n = 268) and female survivors of war in Sri Lanka (n = 149). Three metrics of measurement equivalence—structural, metric, and scalar—were examined. Two- and three-factor structures of the BDI that have been identified in other populations did not provide a good fit for our data. However, a bifactor model revealed a similar general distress dimension across populations, but dissimilar secondary dimensions or subfactors. The Sri Lankan subfactor comprised of predominantly somatic symptoms and the United States subfactor comprised of cognitive and somatic symptoms. While intercepts of individual BDI items differed, their differences seem to be offsetting. Total BDI scores across these two populations are roughly comparable, although caution is recommended when interpreting them. Making comparisons on subscales is not recommended.

The Importance of Positive Need Fulfillment: Evidence From a Sample of War-Affected Sri Lankans.

Eranda Jayawickreme; Nuwan Jayawickreme; Corinne E. Zachry; Michelle A. Goonasekera

There has been growing interest in understanding the psychological and social-environmental factors that facilitate adaptive functioning in populations affected by ethnopolitical warfare. In the current study, we tested the hypothesis that a brief measure incorporating local idioms of positive need fulfilment would predict functioning in a war-affected Sri Lankan population above and beyond psychopathology when controlling for demographic variables and current life stressors. A brief measure of positive need fulfillment was derived from qualitative data and administered to a sample of 163 Sri Lankans affected by the civil war. Positive need fulfillment was found to uniquely predict functioning after controlling for age, war-related life problems, and psychopathology as assessed by the Penn-RESIST-Peradeniya War Problems Questionnaire. These findings highlight the importance of both basic need support and the fostering of agency in addition to addressing mental health needs.
