The Management of Anxiety and Depressive Disorders: A Review

Characteristics of subjects with comorbidity of symptoms of generalized anxiety and major depressive disorders and the corresponding threshold and subthreshold conditions in an Arab general population sample

BACKGROUND

There is controversy about differential meaningfulness between comorbid generalized anxiety disorder (GAD)/ major depressive disorder (MDD), the corresponding "pure" disorders and subthreshold conditions. We compared subjects who met DSM-IVTR criteria of symptoms and functional impairment for comorbid GAD/MDD, versus those with GAD, MDD, subthreshold conditions, and without significant symptoms. The comparison measures were socio-demographics, clinical severity, and quality of life (QOL).

MATERIAL/METHOD

Participants (N=3155: 55.1% female, aged 16-87 yrs) were a general population sample of Kuwaitis who self-completed DSM-IVTR criteria-based questionnaires and the WHOQOL-BREF in 2006/7. We scrutinized the questionnaires and classified them into categories.

RESULTS

Of the 273 GAD and 210 MDD cases, the prevalence of comorbidity among cases with GAD was 30.8%, and 40% among MDD. Of the 398 subthreshold GAD and 194 subthreshold MDD cases, 58 had subthreshold anxiety/depression comorbidity. Comorbid threshold GAD/MDD cases were significantly older, and more likely to be women, divorced and unemployed, compared with GAD and MDD. In all measures, the threshold GAD/MDD comorbidity was the severest condition. There was a monotonic decrease in QOL with increasing anxiety-depression symptoms. For the predictors of subjective QOL, the GAD/MDD comorbidity group differed markedly from the others.

CONCLUSIONS

The high prevalence of comorbidity and subthreshold conditions supports the recommendation to assess them routinely, regardless of the primary reason for consultation. Our findings support a dimensional model with comorbid GAD/MDD at the higher end of a continuum, and differing from the "pure" conditions by a later onset and predictors of subjective wellbeing.

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.

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.
