RELATIONSHIP OF PERSONALITY TRAITS WITH ANXIETY, DEPRESSIVE AND PTSD SYMPTOMATOLOGY AND ACADEMIC PERFORMANCE. Experience with an Arab college student sample.

BACKGROUND: The objective was to highlight the profile of Eysenck Personality Questionnaire traits of a sample of Arab college students, and assess the relationship of trait scores with gender, age and symptoms of anxiety, depression, PTSD and grade point average (GPA) score. Similar reports from the Arab world were restricted to neuroticism/extraversion and rarely involved traumatic experience and psychosocial performance. METHODS: Participants (N = 624) were Kuwaiti national college students who completed, in class, the EPQ- 90, Hopkins Symptoms Checklist, and the PTSD Checklist. RESULTS: Men had higher psychoticism (p < 0.004) and extra- version (p <0.03) scores, while women had higher neuroticism (p < 0.001) and lie scale scores (p < 0.001). Students with the lowest GPA had the highest scores for psychoticism (p< 0.01). Psychoticism and neuroticism were significantly correlated with each other, but negatively with extraversion and lie scale. The correlations of psychopathology were strongest with neu- roticism and psychoticism; and negative with extraversion and the lie scale. In regression analyses, the dominant predictor of psychopathology was neuroticism. With neuroticism as covari- ate, the sex difference in depression scores was no longer sig- nificant. CONCLUSIONS: Our findings support the usefulness of neuroticism as reflecting characteristic level of distress; and a combination of high neuroticism and low extraversion as vul- nerability marker for psychopathology. Psychoticism needs further study as a marker of psychosocial underachievement.

Exploratory factor analytical study of depressive symptomatology: an Arab experience with a sample comprising college students, using the revised Beck Depression Inventory.

BACKGROUND AND OBJECTIVES: An understanding of the domains of depressive symptomatology could facilitate valid and interpretable comparisons across cultures. The objective of the present study was to assess the factor structure of the Beck Depression Inventory-II (BDI-II) in an Arab sample comprising college students, in comparison to the international data. DESIGN AND SETTING: Cross-sectional questionnaire survey of Arab college students in their classrooms over a 1-year period. PATIENTS AND METHODS: Participants (n=624) who completed the questionnaire, which had been translated into Arabic, during the 2007-2008 academic session. Exploratory factor analysis was done by principal axis factoring with oblique rotation. RESULTS: Factor 1 consisted of psychological symptoms. Factor 2 mainly comprised somatic symptoms, but with some affective symptoms (loss of interest, irritability). Factor 3 also belonged to a purely psychological domain, whereas factor 4 was another mixture of somatic and psychological symptoms (41.8% of variance explained). Thus the four domains were as follows: cognitive I, somatic-affective I, cognitive II, and somatic-affective II. These domains were similar in construct to the original subscales on which the BDI-II was validated for students in North America. Our four-factor solution fulfilled the recommended criteria, namely, a strong first factor, simple structure (parsimony), and stable factors with construct meanings that are in line with theory. CONCLUSION: Our factor structure defined depression in a manner consistent with theory, in that sadness, self-dislike, and guilt feelings defined the cognitive domain. whereas irritability and changes in sleep pattern and appetite mostly defined the somatic-affective domain. The BDI-II has construct validity across cultures.

Relationship between symptoms of anxiety and depression in a sample of Arab college students using the Hopkins Symptom Checklist 25.

BACKGROUND: The controversy over the relationship between symptoms of anxiety and depression is an enduring issue. Various models have been proposed to explain this relationship. We explored the following research questions. First, using exploratory factor analysis (EFA), will the symptoms that define anxiety and depression (as in the Hopkins Symptom Checklist 25, HSCL-25) appear together in 1 factor, or are they separable into the hypothesized dimensions of the disorders? Second, using confirmatory factor analysis, how will the structural integrity of the resulting factors compare with those of the various models that have been proposed to explain the relationship between the symptoms of anxiety and depression? This issue has not been investigated in an Arab setting. METHOD: Participants (n = 624) were Kuwaiti national college students, who completed the HSCL-25 in class. EFA was done by principal axis factoring. Seven models were generated for comparison in confirmatory factor analysis, using 8 'fit' indices in Analysis of Moment Structures, version 16. RESULTS: The 5 factors from EFA were similar in construct to the subscales of the Mood and Anxiety Symptom Questionnaire, on which the tripartite model of anxiety and depression was validated ('core anxiety', 'core depression', 'general distress mixed', 'general distress anxiety', 'general distress depression'). The hierarchical bifactor model and the dimensional model characterized by the correlation of these factors were best at meeting the fit indices, followed by the correlated 2-factor anxiety/depression model. In line with theory, the correlation between the specific anxiety/depression factors was lower than that between each of them and the general distress mixed factor; and there was no significant gender difference in the summed score for core depression. CONCLUSION: The findings support the impression that, although the core symptoms of anxiety are separable from the core symptoms of depression, there is an overlapping set of symptoms which contribute to the experience of comorbidity. The relationship between symptoms of anxiety and depression probably has dimensional and hierarchical elements. The findings broaden the evidence base of the cross-cultural validity of the tripartite model.

Dimensional and hierarchical models of depression using the Beck Depression Inventory-II in an Arab college student sample.

BACKGROUND: An understanding of depressive symptomatology from the perspective of confirmatory factor analysis (CFA) could facilitate valid and interpretable comparisons across cultures. The objectives of the study were: (i) using the responses of a sample of Arab college students to the Beck Depression Inventory (BDI-II) in CFA, to compare the "goodness of fit" indices of the original dimensional three-and two-factor first-order models, and their modifications, with the corresponding hierarchical models (i.e., higher - order and bifactor models); (ii) to assess the psychometric characteristics of the BDI-II, including convergent/discriminant validity with the Hopkins Symptom Checklist (HSCL-25). METHOD: Participants (N = 624) were Kuwaiti national college students, who completed the questionnaires in class. CFA was done by AMOS, version 16. Eleven models were compared using eight "fit" indices. RESULTS: In CFA, all the models met most "fit" criteria. While the higher-order model did not provide improved fit over the dimensional first - order factor models, the bifactor model (BFM) had the best fit indices (CMNI/DF = 1.73; GFI = 0.96; RMSEA = 0.034). All regression weights of the dimensional models were significantly different from zero (P < 0.001). Standardized regression weights were mostly 0.27-0.60, and all covariance paths were significantly different from zero. The regression weights of the BFM showed that the variance related to the specific factors was mostly accounted for by the general depression factor, indicating that the general depression score is an adequate representation of severity. The BDI-II had adequate internal consistency and convergent/discriminant validity. The mean BDI score (15.5, SD = 8.5) was significantly higher than those of students from other countries (P < 0.001). CONCLUSION: The broadly adequate fit of the various models indicates that they have some merit and implies that the relationship between the domains of depression probably contains hierarchical and dimensional elements. The bifactor model is emerging as the best way to account for the clinical heterogeneity of depression. The psychometric characteristics of the BDI-II lend support to our CFA results.

Psychopathological status, behavior problems, and family adjustment of Kuwaiti children whose fathers were involved in the first gulf war.

OBJECTIVES: Following the end of the Gulf War that resulted in the liberation of Kuwait, there are no reports on the impact of veterans' traumatic exposure and posttraumatic stress disorder (PTSD) on their children. We compared the severity of anxiety, depression, deviant behavior and poor family adjustment among the children of a stratified random sample of four groups of Kuwaiti military men, viz: the retired; an active -in-the-army group (AIA) (involved in duties at the rear); an in-battle group (IB) (involved in combat); and a prisoners -of- war (POWs) group. Also, we assessed the association of father's PTSD/combat status and mother's characteristics with child psychosocial outcomes. METHOD: Subjects were interviewed at home, 6 years after the war, using: the Child Behavior Index to assess anxiety, depression, and adaptive behavior; Rutter Scale A2 for deviant behavior; and Family Adjustment Device for adjustment at home. Both parents were assessed for PTSD. RESULTS: The 489 offspring (250 m, 239 f; mean age 13.8 yrs) belonged to 166 father-mother pairs. Children of POWs tended to have higher anxiety, depression, and abnormal behavior scores. Those whose fathers had PTSD had significantly higher depression scores. However, children of fathers with both PTSD and POW status (N = 43) did not have significantly different outcome scores than the other father PTSD/combat status groups. Mother's PTSD, anxiety, depression and social status were significantly associated with all the child outcome variables. Parental age, child's age and child's level of education were significant covariates. Although children with both parents having PTSD had significantly higher anxiety/depression scores, the mother's anxiety was the most frequent and important predictor of child outcome variables. The frequency of abnormal test scores was: 14% for anxiety/depression, and 17% for deviant behavior. CONCLUSION: Our findings support the impression that child emotional experiences in vulnerable family situations transcend culture and are associated with the particular behavior of significant adults in the child's life. The primacy of the mother's influence has implications for interventions to improve the psychological functioning of children in such families. Mental health education for these families has the potential to help those in difficulty.

Post-traumatic stress disorder among wives of Kuwaiti veterans of the first Gulf War.

OBJECTIVES: To assess post-traumatic stress disorder (PTSD) among wives of Gulf War Kuwaiti military men, divided into four groups according to degree of combat exposure: the retired, an active-in-the-army group (AIA) (involved in duties at the rear); an in-battle group (IB) (involved in combat); and a prisoners-of-war (POWs) group. To assess the relationship between wives' PTSD and indices of family adjustment, husbands' level of combat exposure, and PTSD status. METHOD: One hundred and seventy-six wives were assessed with the PTSD Checklist for DSM-IV, the family adjustment device, and for anxiety/depression. RESULTS: Fifty (28.4%) fulfilled criteria for probable PTSD. The prevalence was significantly associated with husbands' combat exposure, her presence in Kuwait, but not with husbands' PTSD status. Wives' PTSD was mostly predicted by their depression/anxiety scores. CONCLUSION: The findings support the salience of effective social support, and the need for women empowerment issues in psychosocial intervention for this group.

Prevalence and correlates of posttraumatic stress disorder among Kuwaiti military men according to level of involvement in the first Gulf War.

First, to compare the prevalence and intensity of posttraumatic stress disorder (PTSD) among Kuwaiti military men, divided into four groups (50 subjects each) according to degree of exposure to war trauma: (1) the retired (retired before the invasion); (2) an active-in-the-army group (AIA) (involved in duties at the rear only); (3) an in-battle (IB) group (involved in combat); and (4) prisoners of war (POWs-captured during combat). Second, to compare the severity of impact of event, comorbid depression, and anxiety among the groups. Third, to evaluate the contribution of self-esteem and locus of control (LOC). Subjects were interviewed once, 6 years after the war, using: the Clinician Administered PTSD Scale; the Impact of Event Scale (IES); the Hopkins Symptom Checklist-25; the Internal-External LOC; and The Self-Esteem Scale. Subjects were aged 24-71 years (mean 37.9). Sixty-three subjects (31.5%) fulfilled criteria for PTSD, with the rate significantly higher among the POWs (48%) than the retired (24%) and IB (22%), reflecting the severity of IES. Avoidance symptoms were the most pronounced. Self-esteem was significantly lowest among the POWs and those with PTSD. External LOC was associated with PTSD, anxiety, and depression. Self-esteem was the only covariate of PTSD scores. LOC was a significant covariate for anxiety. The characteristics of PTSD in these veterans showed similarity with those from elsewhere. The prominence of self-esteem and avoidance symptoms implies that they should be part of focus for interventions. Focus on LOC should be from the perspective of anxiety.
