A Conceptual Model and Measurement of Identity-Based, Existential Annihilation Anxieties (EAA)
ABSTRACT
Existential (annihilation) anxiety (EAA) and its significant role in PTSD, complex PTSD and mental and physical health, were a long ignored variable in the mainstream clinical science. Further collective EAA is one of the important dimensions missing in the theory and measurement of EAA. The study evaluated the psychometric properties of an existing measure of existential annihilation scale (EAA) (Kira et al., 2012b), that had previously developed based on an integrative framework of identity-based existential annihilation anxiety (EAA) that include most of the personal and collective dimensions of EAA. We reanalyzed the data in seven studies that utilized the measure, conducting exploratory and confirmatory factor analysis for the pooled data (N = 2436), as well as path analysis with EAA as a mediator of the effects of cumulative stress and trauma on PTSD. We conducted Multigroup invariance to test the invariance of the measurement model as well as the predictive structural model across groups. The short measure found to have good internal consistency and test-retest stability, as well as construct, convergent, divergent and predictive validity and is strongly invariant across the main groups. As hypothesized, by the integrated model of EAA, EAA fully mediated the effects of cumulative trauma on PTSD. The results confirm at least in part the validity and utility of the integrative conceptual framework. Further development of the measurement model in future studies was proposed to include fear of death that was not included in the evaluated measure and is one of the components of integrated framework of EAA. The importance of integrating EAA in the mainstream clinical science and intervention was discussed.

1. Introduction

Existential (annihilation) anxiety (EAA) and its significant role in PTSD, complex PTSD and mental and physical health, were a long ignored variable in the mainstream clinical science. Integrating its conceptual models in studying PTSD, complex PTSD and post-cumulative stress and trauma disorders was mostly resisted. Developing an integrated conceptual framework of EAA and publishing and disseminating solid empirical research was resisted by most peer-reviewed journals from both traditionally dominant sides: the psychoanalytical and the cognitive-behavioral focused journals. The focus in clinical psychology and related disciplines was more on general anxiety. Specific existential anxieties intensified by threats to the existence of one or more of the person’s multiple identities represent the most severe anxieties. Specific anxieties about such threats are mostly under-studied in clinical, social and political psychology. Further, existing studies of different existential anxieties are fragmented and do not present a coherent framework. Innovative conceptual and empirical integration that combine and refine the different models of existential anxieties is important to improve our understanding of its dynamics and its effects on mental and physical health. In current article, we will conceptually and empirically integrate different kinds of existential anxieties, annihilation anxieties, and death anxieties frameworks and propose a measurement strategy to test the validity and utility of the integrated conceptual model.

Existential anxieties (EA) (anxieties caused by events that threatened the existence of one of the person’s identities) (e.g., Berman, Weems, & Stickle, 2006; Shaver, & Mikulincer, 2012; Weems, Costa, Dehon, & Berman, 2004 ), annihilation anxieties (AA) (fear of being overwhelmed, merged, penetrated, fragmented, and destroyed, that is triggered by survival threats) (e.g., Hurvich, 2004; Allen, Hurvich, & Mcguire, 2017 ), and death anxiety (anxiety caused by the anticipation of death) (e.g., Iverach, Menzies, & Menzies, 2014 ) and mortality salience (the inevitability of dying) (e.g., Burke, Martens, & Faucher, 2010 ) are unique but overlapping conceptual frameworks. They are all related to severe threats to some of the person’s different identities with different intensities of related anxieties. Existential Annihilation anxieties (EAA) can be a unifying and integrative concept that includes anxieties that may erupt upon exposure to person’s different personal, role, physical and social identities. EAAs, in the proposed framework, significantly contribute to mediating the effects of cumulative trauma on PTSD and mental health.

Annihilation anxiety (AA) proposed in psychoanalytic literature is a very broad concept, but unfortunately has been seen through a very narrow lens, i.e., the psychic anxieties about the mere existence of the person’s psychic (i.e., personal) identity, ignoring the existential threats to the person’s social and physical identities. Annihilation Anxiety indeed is a constant confrontation with dangers to psychic survival. Death anxiety, on the other hand, is the anxieties about the inevitable physical death of the individual or current threats of physical elimination. Psychic anxieties and fear of death are focused on different anxieties about the existence of different identities of the individual. Further, these two frameworks have an individualistic bias. The social dimensions of the individual’s, which is one of his /her core existence, are ignored in these frameworks. Collective AA anxieties (anxiety caused by events that threaten one of the person’s groups of belonging, or his collective identities) may be triggered by events that threaten the individual’s group existence. Examples are the Holocaust and other genocides, and similar events set off by the dynamics of inter-group conflicts. Further, fear of the extinction (or the demise) of a group, a nation, a civilization or the species, implied in the atomic age, globalization and climate change and the potential end of life can be another dimension related to EAA (Kira, 2002) . End of life was predicted and part of core beliefs in most religious traditions.

Additionally, threats to social identity status in severe discriminations, intense power, and status struggle (e.g., caste system, slavery), and unemployment are not directly included in any of current popular frameworks. The loss of self-perceived social status but not the loss of income or social support explained a significant variance for the adverse health effects of unemployment (Krug, & Eberl, 2018) . While anxieties about existence can vary in their intensities, existential annihilation anxieties (EAA) represent the severe endpoints in the continuum of such anxieties.

There is a lack of a conceptual integrative model of EAA and comprehensive parsimonious tools for its measurement that are based on robust, comprehensive theoretical grounding.

Identity-Based EAA Conceptual Framework

The proposed conceptual framework is based on the developmentally-based trauma framework (DBTF) ( Kira , 2001;Kira et al., 2013b; Kira et al., 2010; Kira et al., 2015; Kira, Lewandowski, Chiodo, & Ibrahim, 2014; Kira, et al., 2018a), and collective terror management theory (CTMT) ( Kira, 2002 ). According to DBTF and CTMT, EAA may develop in the individual starting with the individuation processes in early adolescence through adulthood. Identity development through individuation processes marks the emergence and development of agency and interdependence leading to establishing a hierarchy of different intersecting and interacting identities. Some of these identities are more salient or more dormant according to the triggering events and situations. Identity development is related to self-awareness and core beliefs about self, belongings, and meaning in life. Identity hierarchy, as discussed earlier, includes personal, colI. A. Kira et al. DOI: 10.4236/psych.2018.96080 1309 Psychology lective or social, role/status and physical identities. Concerns about the existence, maintenance and continuous emergence of individual’s identities can escalate upon exposure to relevant and important threats, stressors, and traumas (e.g., Kira, 2006; Kira, Alawneh, Aboumediane, Mohanesh, Ozkan, & Alamia, 2011; Kira, Shuwiekh, Al Ibraheem, & Aljakoub, 2018b; Kira, Shuwiekh, Kucharska, Abu-Ras, & Bujold-Bugeaud, 2017; Kira, Shuwiekh, Rice, Al Ibraheem, & Aljakoub, 2017). Such exposure can trigger existential fears of the annihilation of one or all of her/his identities. Psychic EAA emerges when personal identity (i.e., autonomy, agency) is threatened by impending traumatic events such as sexual abuse or rape. Collective EAAs emerges when one of the important groups that the person closely identifies with is threatened, demeaned, or assigned comparative inferior status by other strong competitor or dominant groups (e.g., Kira, Shuwiekh, & Bujold-Bugeaud, 2015; Kira et al., 2010; Kira, Shuwiekh, & Bujold-Bugeaud, 2017). EAAs may emerge upon events or chronic conditions that seriously threaten a core achievement/self-actualizing goal or socio- economic status of the individual. Examples are extreme inequalities, poverty, and cast systems, as well as a failing business or education that threatens the individual’s socio-economic status and self-evaluations. The fourth major source for EAAs is events that threaten physical survival, i.e., death. Collective identity or type III traumas, such as different discriminations and extreme inequality were found to be the worse trauma type that can impede post-traumatic growth (Kira et al., 2013a). To recap, according to the DBTF and CTMT, there are four major sources of EAA (Kira et al., 2012a): the threats to personal identity’s psychic annihilation, the threats to collective and social identities, the threats to identity status by social structure traumas (social-structural violence), and the threat to the physical identity of the individual. These four types of threats, when concurrently exist can intersect in amplifications loop.

The threats to the physical identity are the main focus of current psychiatric trauma and terror management theories. Mortality salience, death threat and the resulted fear of physical annihilation (i.e., death) is the focus of terror management theory. Fear of personal identity psychic annihilation is the focus of annihilation anxiety theory in psychoanalytic literature. However, fear and anxieties around collective annihilation of one or more of the person’s social identities or social identity status, and extinction salience is almost missing variables in the mainstream psychology. As noticed, the current mainstream psychology, has an individualistic bias (e.g., Christopher & Hickinbottom, 2008 ), ignoring an important part of the personal existence, which make it deficient and unable to predict or develop strategies to prevent group-based violence. Group-based violence is one of the current challenges to our discipline. Yet, political psychology recognizes the importance of the concept of collective annihilation anxieties in the Holocaust and genocides studies (e.g., Hirschberger, Ein-Dor, Leidner, & Saguy, 2016; Kira, Alawneh, Aboumediene, Lewandowski, & Laddis, 2014; Shrira, 2015; Yair, 2014; Wohl, Branscombe, & Reysen, 2010 ).

Fear of physical death is related to the salience of mortality for individuals, while fear of group existential annihilation is more related to the extinction salience of the groups, cultures, and civilizations, and potentially species (Kira, 2002) . Death or mortality salience and related terror management strategies (e.g., Pyszczynski, Greenberg, & Solomon, 1999 ) may be different from or intersect and interact with collective terror management strategies (CTM) related to identities’ extinction salience. Core strategies that may buffer or alleviate CTM related anxieties include, strong will to exist, live and survive, religiosity, and spirituality, which help the individual to potentially recover from the terror related to the inevitability of extinction (e.g., group annihilation), and to threats to group identity and recover his/her positive self-evaluation (self-esteem) and perceived social status.

One of the goals of this paper is to further develop a measurement model of EAA that covers its different dimensions. We will evaluate the psychometric properties of one measure of EAA that initially reflected some dimensions of this framework, and use the results to test the framework basic assumptions and to explore further the development of a comprehensive measurement model for EAA.

Measuring EAA

Hurvich Experience Inventory (HEI), and its different versions (Allen, Hurvich, & Mcguire, 2017) is a self-report protocol that associate with projective measures of annihilation anxiety (Hurvich, Benveniste, Howard, & Coonerty, 1993) , try to measure the psychoanalytic concept of personal identity-related annihilation anxiety. They are many measures of existential anxiety (EA) with most of them is focused on fear of death (e.g. van Bruggen, Vos, Westerhof, Bohlmeijer, & Glas, 2015 ). A recent attempt to introduce and measure EAA, from an integrative theoretical framework that includes especially group-based existential AA and social status related AA, in addition to the psychic annihilation fears is proposed by Kira and Colleagues (Kira et al. 2012b; Kira, Shuwiekh, Rice, Al Ibraheem, & Aljakoub, 2017) . The developed short measure has good reliability, strong divergent and predictive validity and fits the theoretical assumptions that underlie the construct. The measure is not intended to be a diagnostic tool and can be useful in clinical screening, advanced case conceptualization, and in psychological and political research, especially with the multiply traumatized. Several subsequent studies using the measure help provide an accurate picture of its psychometric properties.

One of the goals of this paper is to evaluate and further develop the AA short measure based on the published studies and collected data and a more developed conceptual framework. The study hypothesized that the short measure will have good reliability, stability, convergent, divergent and predicative validity. According to the proposed theory, we further hypothesized that EAA will significantly mediate the effects of cumulative trauma on PTSD. While the EAA conceptually is multidimensional, we expect that a one first or second order unitary factor will emerge as the theory proposed the intersection of all types of EAA that belong to the same person.

2. Methods

2.1. Procedures

There are three adult samples and four adolescent samples that utilized this short three items measure. In the current study, we combined the seven samples in one dataset (N = 2436).

The scale developers assumed that there are at least three primary sources of the emergence of annihilation threats. They include threats to personal identity, collective identity, and threats from severe societal structural inequalities. Three items, each represents one of the three components was used, e.g., “Because of what has happened to me personally or is happening to me personally, I sometimes worry that I just lose my sense of self (I worry that I will cease to exist as a person).” The answer was structured on a 5-point Likert-scale (5 = strongly agree; 4 = agree; 3 = not sure; 2 = disagree; 1 = strongly disagree). A score of 3 or higher on any item indicates the presence of at least one related concern.

Researchers used the 3-item scale previously for Iraqi refugees in Michigan, on three samples of Palestinian adults and adolescents and of mental health clients (N = 399). In the initial validation study and subsequent studies, its alpha reliability ranged from .90 - .95, and its convergent, discriminant and predictive validity were adequate (Kira, et al., 2012b) . In the validation study, using multiple regression, although all trauma types predicted AA, collective identity trauma was the highest predictor (β = .74, p < .001). Negative appraisal of different survival and identity traumas was a stronger predictor of AA than just the occurrence of trauma. AA was found to be a significant predictor of PTSD (β = .46, p < .001), cumulative trauma disorder (CTD; β = .43, p < .001), general anxiety (β = .40, p < .001), depression (β = .38, p < .001), and poor self-rated health (β = .14, *p < .01). Annihilation anxiety mediated the effects of cumulative negative appraisal on mental and physical health. AA highly associated with the CTD-Dissociation/Psychosis Sub-scale. The research found similar results in subsequent studies on Palestinians (Kira, Alawneh, Aboumediene, Lewandowski, & Laddis, 2014) , and Syrians refugees (Kira, Shuwiekh, Rice, Ibraheem, & Aljakoub, 2017) .

Family size average was 9.77 with SD of 2.79. For detail see Kira et al., 2011 .

2.3. Statistical Analyses

The data were analyzed utilizing IBM-SPSS 22 and Amos 22 software. Comparing Cohen (1992) sample size recommendations to achieve medium population effect size at power = .80 for α = .05 for the number of variables, the sample size of each group was adequate and the combined sample (N = 2436) far exceeded the recommended sample size to achieve a high effect size considering the number of the dependent variables in the correlation matrix. We conducted zero-order correlation between EAA and the other relevant variables in each of the studies to check the consistency of its divergent and predictive validity indicators across studies. To determine the EAA’s structural validity and its factor structure scores, we split the combined sample of the seven studies (N = 2432) into two subsamples (N = 1218 each) using SPSS commands (e.g., select a random sample of the cases). We conducted exploratory (on the first sub-sample) and confirmatory factor analysis (on the second subsample). We conducted confirmatory factor analysis on the scale as a unitary factor. Following Byrne’s (2012) recommendations, the measurement model was evaluated to ensure an acceptable fit with the sample data. The criteria for good model fit were a non-significant chi-square (χ2), chi-square/degrees of freedom (χ2/d.f. > 5), comparative fit index (CFI) values > 0.90, and root-mean-square error of approximation (RMSEA) values < 0.06 (Weston & Gore, 2006) . We investigated the reliability of the scale with the Cronbach’s alpha technique and its stability by the test-retest procedure. To test its predictive validity, we conducted path analysis between the independent and dependent variables. We used a bootstrap procedure with 10,000 bootstrap samples to examine the significance of direct, indirect and total effects and 95% bias-corrected confidence intervals.

To assess whether the EAA scale is invariant across different samples and genders, we conducted multi-group invariance analysis. Further, we conducted similar analysis to determine if the predictive model of EAA in invariant across groups. Although there is broad acceptance of the steps for testing measurement invariance, the criteria for evaluating the fit of the models at each level are not as clear (see, e.g., Meade, Johnson, & Braddy, 2008 ). The statisticians propose guidelines for evaluating model fit, but there are no widely agreed on absolute criteria for determining whether the constraints in a model lead to an unacceptable level of the misfit. When evaluating models, we focus on the (RMSEA), the (CFI), and the Tucker-Lewis index (TLI). We used the guidelines that well-fitting models will have RMSEAs at or below 0.08. If adding invariance constraints in a model (a more restrictive model) lead to a substantial decline in fit indices in comparison with a less restrictive model, the invariance constraints are not supported. If imposing invariance constraints in a model (a more restrictive model) does not lead to a substantial decrement in fit indices in comparison with the less restrictive model, the strict invariance is accepted. The null hypothesis of invariance should not be rejected when changes in CFI are less than or equal to .01, and if RMSEA is less than or equal to .015 (Chen, 2007) .

Four invariance nested models were tested sequentially: a configural invariance model, a metric invariance model, a scalar invariance model, and a strict invariance model. In the configural model, (i.e., equal form), the parameters are all freely estimated across groups. In the metric model (i.e. weak or partial invariance), the parameters are constrained to be identical across groups. In the scalar model or “strong invariance”, variables and paths variances are set to be equal across groups. Lastly, the strict model “strict invariance” additionally constrains the residuals to be the same across the samples.

3. Results

3.1. Descriptive Differences between Groups in EAA

Using ANOVA with multiple comparisons, there were no significant differences between the scores on EAA between the seven groups except for the differences between African American and Iraq refugee adolescents. Adults in Gaza scored the highest followed by mental health clinic patients in all of the three types of EAA (personal identity (psychic) EAA, collective identity EAA, and status identity EAA) and of the total score. Gaza adults and mental health clinic patients scored the highest on all the measured types of EAA and the differences were highly significant, which further give an indication for its discriminant validity and its ability to identify the most traumatized and the clinical populations. Figures 1-4 present the plots of means of each of the EAA type and for the total score for the seven samples. Table 1 provides the means, standard deviations

and standard errors and lower and upper bound of 95% confidence interval of the mean score of EAA total score in each sample.

3.2. Correlational Results

EAA significantly correlated with PTSD and all its four subscales. It associated with depression, poor health, with cumulative trauma, with identity salience, with identity traumas (collective and personal), with birthing trauma and gender discrimination, as well as survival and to some extent secondary traumas. It associated with poverty. It associated with fear of death. It was associated with the internalized stigma of mental illness in the mental health clinic sample. It was associated with negative appraisal of stressful and traumatic events. All these associations lent support to the EAA conceptual, construct, convergent and predictive validity. It was associated negatively with stress-related growth, futuristic orientation, and optimism, which lend support to its divergent validity. Table 2 summarizes these correlations.

3.3. Reliability and Stability

Alpha reliability ranged in the seven data sets between .70 and .93, with the highest in the clinic sample (.93). The reliability of the pooled data (N = 2743) was .80. Test-retest reliability in a small sample of 35 and the 6-week interval was .94.

Factor Analysis: Exploratory and Confirmatory and the invariance of the measurement model.

Using the first split sample of adults and adolescent (N = 1216), we conducted Principal.

Component Factor Analysis of the scale. The analysis yielded one factor accounted for 72.16% of the variance. Table 3 includes commonalities and factor loadings of each item.

Using the second split sample (N = 1218), we conducted confirmatory factor analysis. The one factor scale had good fit with the data (Chi Square = .015, d.f. = 1, p = .903, CFI = 1.00, RMSEA = .000). Figure 5 provides the results of the confirmatory factor analysis.

Further, a multigroup analysis was conducted to examine the measurement invariance of the scale across genders. We tested for configural invariance (same variables and paths for each variable across the two samples). Results showed an acceptable model fit, (Chi-square = 2.655, df = 2, Chi-square/df = 1.327, p > .265, RMSEA = .000, CFI = 1.000, and IFI = 1.000, TLI = .999). The second

model (metric or weak invariance) model holding all variables and paths values invariant across groups showed good fit as well, with no significant reduction in the model fit, (Chi-square = 3.332, df = 3, Chi-square/df > 5, p = 0.343, RMSEA = 0.007, CFI = 1.000, IFI = 1.000, and TLI = 1.000), which means that the model is invariant at this level of analysis. The third model (strong invariance or scalar invariance model in which intercepts additionally restrained), and the fourth model (strict invariance model in which residuals additionally restrained), the fit indicators, showed a similar acceptable range of invariance. These results indicate that the scale is strictly invariant across genders. Table 4 presents the results.

3.4. The Predictive Validity of the EAA and Its Invariance

We conducted path analysis, on the combined data, in which of EAA mediated the effects of cumulative trauma on PTSD’ four major components (re-experiencing, arousal, avoidance, and dissociation), with PTSD as a latent variable. The model fits well (Chi Square = 9.452, d.f. = 7, p = .222, CFI = .000, RMSEA = .012). In this model, EAA fully mediates the effects of cumulative stress and trauma on all PTSD four components. Figure 6 presents the path models that map the direct effects and Table 5 presents the direct, indirect and total effects and their 95% confidence intervals for the variables in the model.

Further, we conducted a series of Multigroup structural invariance analyses to test the invariance of the predictive path model across genders, across different adult groups and different adolescents groups and across age groups (adults vs. adolescents). For its invariance across genders, we tested for configural invariance. Results showed an acceptable model fit, (Chi-square = 16.743, df = 14, p > .270, RMSEA = .009, CFI = .000, and IFI = .000, TLI = .999). The second model (metric or weak invariance) model holding all variables and paths values invariant across groups showed good fit as well, (Chi-square = 33.785, df = 17, Chi-square/df > 5, p = .343, RMSEA = .020, CFI = .998, IFI = .996, and TLI = .998), which means that the model is variant at this level of analysis. The third model

(strong or scalar invariance model in which intercepts additionally restrained), and the fourth model (strict invariance model in which residuals additionally restrained), the fit indicators, showed similar acceptable range. These results indicate that the scale’s predictive validity is strictly invariant across genders. Table 5 provides different fit indicators for each model. For the path predictive model invariance across adult groups, we tested for configural invariance. Results showed an acceptable model fit, (Chi-square = 21.571, df = 18, Chi-square/df = 1.198, p .252 > 5, RMSEA = .013, CFI = .999, and IFI = .999, TLI = .997). The second model (metric or weak invariance) model holding all variables and paths values invariant across groups showed good fit as well, (Chi-square = 36.004, df = 24, Chi-square/df > 5, p = .055, RMSEA = .021, CFI = .996, IFI = .978, and TLI = .969), which means that the model is invariant at this level of analysis. The third model (strong or scalar invariance model in which intercepts additionally

restrained) was also acceptable. However, for the fourth model (strict invariance model in which residuals additionally restrained), some of the fit indicators, did not show an acceptable range. These results indicate that the scale predictive validity is strongly (not strictly) invariant across different adult groups. Table 5 provides different fit indicators for each model.

For predictive path model invariance across adolescents groups and age groups (adolescents vs. adults), results showed an acceptable model fit for the first three models. For the fourth model (the strict invariance) some of the fit indicators did not show an acceptable range. The results indicate that the scale’s predictive validity is strongly (but not strictly) invariant across adolescents groups and age groups. Table 6 provides the fit indicators for each model for these groups.

4. Conclusions, Discussion, and Proposed Future Development

Current study tested some assumptions of an integrated model of existential annihilation anxieties using a short parsimonious measure of EAA. The measure that contained three different models of EAA found to be unidimensional which validate the intersectionality hypothesis. Existential anxieties from different sources intersect, feed and amplify each other, as they belong to the same person’s existence. EAA found to fully mediate the effects of cumulative trauma on PTSD. This paper charts an alternative trajectory for the integrative study of EAA, asserting that analytic priority rests with understanding identity dynamics and its implications for the integrative theory of EAA. It provided evidence for the clinical importance of all components of EAA, especially those related to the social EAAs that rarely addressed or measured in the literature.

While mortality salience and psychoanalytic psychic AA are important dynamics, extinction salience of the group, can be equally powerful for some individuals and groups and have significant clinical implications. Mortality salience

can intersect and interact with the extinction salience within the person’s identities hierarchy. In factor analysis, group EAA had the highest commonality and loading on the single factor that found to represent EAA and accounted for 72.16% of the variance. Further, the different types of EAA found to represent one factor which provided evidence of the validity of the integrative approach of intersecting and interacting identity trauma-based EAA. Future research may plan to establish profiles of EAA in different trauma victims (e.g., torture survivors, veterans, sexual abuse survivors, Holocaust and genocide survivors, minorities, and refugees).

Additionally, the current study established the reliability, stability and predictive validity of EAA measure. EAA short form seems to have good psychometric properties with multiply traumatized and clinical populations. Its correlations reflect the good content and conceptual, as well as discriminant and predictive validity. It seems to possess good internal consistency and test-retest stability. It is a parsimonious tool to measure this developed concept. It is easy to use in research projects with multiple traumatized in clinical and non-clinical settings and with adults and adolescents.

In path analysis, EAA fully mediated the effects of cumulative trauma on PTSD, which emphasizes the clinical importance of this long-ignored existential dimension. Recent studies on Syrian refugees in Egypt and the Netherlands and internally displaced replicated these findings and found similar results on the role of EAA in PTSD and other mental health conditions (Al-Ibraheem, Kira, Aljakoub, & Al-Ibraheem, 2017; Kira, Shuwiekh, Al Ibraheem, & Aljakoub, 2018b; Kira, Shuwiekh, Rice, Al Ibraheem, & Aljakoub, 2017) . These findings are important to developing more convincing conceptual frameworks and more effective intervention strategies that target EAA in all its components.

However, this short measure though parsimoniously measured most dimensions of the integrated framework; it does not cover all the dimensions discussed in the introduction (does not include enough items that measure role/status identity, and physical identity). To measure this concept in all its dimensions, we developed an expanded version (see Appendix). The measure includes fifteen items that include four subscales: EAA related to personal identity traumas subscale, EAA related to collective identity traumas subscale, EAA related to role/status identity (e.g., relative deprivation and personal achievement and self-actualization) subscale, and EAA related to fear of death. The new scale with its four subscales gives the researcher the option to use one subscale or the other to measure EAA resulted from different threats to different identities, or, alternatively to map the profile of different EAA intensities using the whole scale. Alternatively, the three items short measure discussed here has good psychometrics and is available for research especially with multiply traumatized that may not have the attention span to tolerate longer measures and questionnaires (Allen, Hurvich, & Mcguire, 2017: p. 7) . The EAA scale is not intended for diagnostic purposes, rather for different relevant clinical, social and political research and for advanced clinical case conceptualization. Future studies would be conducted to test this expanded version of EAA with its four subscales.

Appendix

Existential Annihilation Anxiety (EAA) Scale (Long Form)

Many people have experienced different kinds of events and situations in their lives that challenged their existence personally, or the existence of one of the groups to which they belong. Such challenges may threaten them and made them worry about themselves, their status, their identity or their existence as a person or as a member of the group (for example religious, cultural or ethnic group). These next questions will ask you about some specific situations that may or may not have happened to you in the past (during your life) that may let you feel an existential or annihilation threat. Please rate, if you agree or you disagree with each statement according to the scale indicated after each question:

____1. Because of what has happened to me personally or is happening to me now, I sometimes worry that I just lose my sense of self (I worry that I will cease to exist as a person).

Strongly Agree Agree Somewhat Agree Disagree
