Torture survivors' symptom load compared to chronic pain and psychiatric in-patients.

Before their entry into the rehabilitation program at the Rehabilitation and Research Centre for Torture Victims ('RCT') in Copenhagen, the degree of symptoms of a group of resettled traumatized refugees was assessed by means of two rating scales: the Disability Rating Index (DRI) (n=197), measuring pain-related functional disability, and the Hospital Anxiety and Depression Scale (HADS) (n=147). The results obtained were compared with other patient populations, which included (1) a large Swedish mixed pain group and (2) various groups of pain patients previously investigated in the validation study of the DRI scale. The DRI scores of the refugee group were comparable to, or higher than, those of the pain groups, except for patients suffering from multiple sclerosis. The degree of anxiety and depression was found to be considerably greater in the refugee group than in the pain groups. Another recently published Danish study comparing traumatized refugees with psychiatric in-patients in terms of Health of Nation Outcome Scores (HoNOS) documented a higher degree of psychiatric disability for refugees. Based on the hypothesis that the observed differences in this study were underestimated due to the exclusion of refugees with psychotic symptoms and substance abuse, a partial re-analysis of the data was carried out by calculating effect sizes with and without the items measuring these symptoms. Controlling for the exclusion of the critical items resulted in a more pronounced difference between the refugees and psychiatric inpatients. Based on the data compared in this study, traumatized refugees are shown to suffer from multiple problems, including chronic pain, at a high symptom-level. This challenges prior clinical assumptions that single factors like PTSD can explain all symptoms.

Using data from Multidimensional Pain Inventory subscales to assess functioning in pain rehabilitation.

The aim of this study was to examine whether Multidimensional Pain Inventory (MPI) subscale score changes can be used for monitoring interdisciplinary cognitive behavioural pain rehabilitation programmes, using the Psychological General Well-Being (PGWB) index as an independent variable of rehabilitation outcome. Data from 434 consecutively referred patients disabled by chronic pain were analysed. The intervention was a 4-week interdisciplinary pain rehabilitation group programme (5 h/day), based on biopsychosocial and cognitive behavioural principles. Mean PGWB total scores improved after rehabilitation (P<0.0001) with clinically relevant effect sizes for patients with 'dysfunctional' and 'interpersonally distressed' MPI profiles. Substantial correlations (r=0.7-0.3; P<0.001) were found between the changes in PGWB total scores and four of the MPI subscale scores. These were combined into a composite variable ['pain severity', 'interference', 'life control' (given reversed scores) and 'affective distress'], and were labelled as the Pain Rehabilitation Index. The subscales, 'support' and 'general activity level', were omitted, as changes were ambiguous with respect to functioning. 'Dysfunctional' and 'interpersonally distressed' profile patients showed a marked improvement in Pain Rehabilitation Index after rehabilitation (effect sizes of 0.77 and 0.43; P<0.0001, respectively). Conversely, the 'adaptive copers' may have deteriorated somewhat (effect size -0.28; P=0.036). We propose that scores from four MPI subscales are integrated and the difference pre-post rehabilitation is used to indicate composite rehabilitation outcomes, making it possible to interpret all included MPI subscales in the same direction. Psychometric evaluation of the index is warranted.

One-year follow-up of cognitive behavioral therapy for phobic postural vertigo.

BACKGROUND: Phobic postural vertigo is characterized by dizziness in standing and walking despite normal clinical balance tests. Patients sometimes exhibit anxiety reactions and avoidance behavior to specific stimuli. Different treatments are possible for PPV, including vestibular rehabilitation exercises, pharmacological treatment, and cognitive behavioral therapy. We recently reported significant benefits of cognitive behavioural therapy for patients with phobic postural vertigo. This study presents the results of a one-year follow-up of these patients. METHODS: Swedish translations of the following questionnaires were administered: (Dizziness Handicap Inventory, Vertigo Symptom Scale, Vertigo Handicap Questionnaire, and Hospital Anxiety and Depression Scale) were administered to 20 patients (9 men and 11 women; mean age 43 years, range 23-59 years) one year after completion of cognitive behavioral therapy. RESULTS: Test results were similar to those obtained before treatment, showing that no significant treatment effects remained. CONCLUSION: Cognitive behavioral therapy has a limited long-term effect on phobic postural vertigo. This condition is more difficult to treat than panic disorder with agoraphobia. Vestibular rehabilitation exercises and pharmacological treatment might be the necessary components of treatment.

Experience of handicap and anxiety in phobic postural vertigo.

CONCLUSIONS: We found a difference in gender distribution in a population of phobic postural vertigo patients compared with dizzy patients seen in general neuro-otological practice. It appears as if women with phobic postural vertigo suffer more and are more handicapped by dizziness than both men with phobic postural vertigo and a population with dizziness. These differences may reflect other causes of phobic postural vertigo besides anxiety, such as gender-related coping behaviour and postural strategy. OBJECTIVE: Anxiety influences the degree of suffering and handicap in dizzy patients. Experiences of anxiety and handicap were investigated among a population with phobic postural vertigo. MATERIAL AND METHODS: Using the Dizziness Handicap Inventory, the Vertigo Symptom Scale and the Vertigo Handicap Questionnaire, 34 consecutive patients with phobic postural vertigo were compared with a population of 95 consecutive patients seen at a balance disorder clinic. RESULTS: Patients with phobic postural vertigo scored higher than the control subjects with respect to all parameters with the exception of the physical subscale of the Dizziness Handicap Inventory. Because there were significantly more women in the control group we performed a gender-specific analysis of the results. The higher test scores among patients with phobic postural vertigo can be explained by the higher scores among women in this group, while the test results for men were more similar to those of the control group.
