Prevalence of Posttraumatic Stress Disorder in Persons with Chronic Pain: A Meta-analysis

ObjectiveTo summarize evidence for the prevalence of posttraumatic stress disorder (PTSD) among persons with chronic pain (CP).MethodsWe searched databases for studies published between January 1995 and December 2016, reporting the prevalence of PTSD in persons with CP. Two reviewers independently extracted data and assessed the risk of bias. We calculated the pooled prevalence using a random-effects model and performed subgroup analyses according to pain location, the population and assessment method.ResultsTwenty-one studies were included and the PTSD prevalence varied from 0–57%, with a pooled mean prevalence of 9.7%, 95% CI (5.2–17.1). In subgroup analysis, the PTSD prevalence was 20.5%, 95% CI (9.5–39.0) among persons with chronic widespread pain, 11.2%, 95% CI (5.7–22.8) among persons with headache, and 0.3%, 95% CI (0.0–2.4) among persons with back pain. The prevalence in clinical populations was 11.7%, 95% CI (6.0–21.5) and in non-clinical populations 5.1%, 95% CI (0.01–17.2). In studies of self-reported PTSD symptoms, PTSD prevalence was 20.4%, 95% CI (10.6–35.5), and in studies where structured clinical interviews had been used to assess PTSD its prevalence was 4.5%, 95% (CI 2.1–9.3). The risk of bias was medium for most studies and the heterogeneity was high (I2 = 98.6).ConclusionPTSD is overall more prevalent in clinical cohorts of persons with CP and particularly in those with widespread pain, but may not always be more prevalent in non-clinical samples of persons with CP, compared to the general population. There is a large heterogeneity in prevalence across studies. Future research should identify sources of heterogeneity and the mechanisms underlying the comorbidity of the two conditions

Own and parental war experience as a risk factor for mental health problems among adolescents with an immigrant background: results from a cross sectional study in Oslo, Norway

BACKGROUND: An increasing proportion of immigrants to Western countries in the past decade are from war affected countries. The aim of this study was to estimate the prevalence of war experience among adolescents and their parents and to investigate possible differences in internalizing and externalizing mental health problems between adolescents exposed and unexposed to own and parental war experience. METHOD: The study is based on a cross-sectional population-based survey of all 10(th )grade pupils in Oslo for two consecutive years. A total of 1,758 aadolescents were included, all with both parents born outside of Norway. Internalizing and externalizing mental health problems were measured by Hopkins Symptom Checklist-10 and subscales of the Strengths and Difficulties Questionnaire, respectively. Own and parental war experience is based on adolescent self-report. RESULTS: The proportion of adolescents with own war experience was 14% with the highest prevalence in immigrants from Eastern Europe and Sub-Saharan Africa. The proportion of parental war experience was 33% with Sub-Saharan Africa being highest. Adolescents reporting own war experience had higher scores for both internalizing and externalizing mental health problems compared to immigrants without war experience, but only externalizing problems reached statistically significant differences. For parental war experience there was a statistically significant relationship between parental war experience and internalizing mental health problems. The association remained significant after adjustment for parental educational level and adolescents' own war experience. CONCLUSION: War exposure is highly prevalent among immigrants living in Oslo, Norway, both among adolescents themselves and their parents. Among immigrants to Norway, parental war experience appears to be stronger associated with mental health problems than adolescents own exposure to war experience

Perceived current needs, psychological distress and functional impairment in a war-affected setting: a cross-sectional study in South Sudan

Objectives To examine the current perceived needs of the general population in a war-affected setting, and to study the influence of perceived needs on the participants’ mental health status and functional impairment across genders. Methods A cross-sectional community survey (n=464) was conducted in war-affected South Sudan. Three regression models were analysed. Perceived needs were assessed with the Humanitarian Emergency Settings Perceived Needs Scale. Psychological distress was measured with the General Health Questionnaire and level of functioning by the Short Form Health Survey (SF-12). Results The most frequently expressed needs were related to drinking water, alcohol and drug use in the community and access to sanitation facilities. No gender differences were found regarding the level of perceived needs or the number of traumatic events. Higher level of perceived needs significantly predicted psychological distress and lower level of functioning even when numbers of experienced trauma events were taken into account. Conclusions The associations of higher level of needs and trauma experiences, on the one hand, and negative health outcomes on the other, necessitate a greater integration of interventions directed towards the population's perceived needs and mental health, particularly for those who have been exposed to trauma

The objective of this study was to describe prevalence of alcohol use and risky drinking across socio-demographic factors in South Sudan, and to determine the association between risky drinking, traumatic events and mental distress. Methods This is a randomized, population based, cross-sectional study from the north-western part of South Sudan with nearly 500 participants. We used the Alcohol Use Disorders Identification Test (AUDIT) as main outcome variable, the General Health Questionnaire (GHQ-28) for mental distress and five questions to assess traumatic events. Results The mean AUDIT score was 2.7 (SD 0.3) with 14,2 % in the high risk problem drinking category. Being male, lack of a regular income and psychological distress were significantly associated with higher AUDIT score. Traumatic events, however, was not associated with higher score on AUDIT. Conclusion Despite decades of civil war and great poverty the alcohol use in this population was at the same level as other countries in Southern Africa. Traumatic events were not related to risk of problem drinking

Better mental health in children of Vietnamese refugees compared with their Norwegian peers - a matter of cultural difference?

<p>Abstract</p> <p>Background</p> <p>There are conflicting results on whether immigrant children are at a heightened risk of mental health problems compared with native youth in the resettlement country.</p> <p>The objective of the study</p> <p>To compare the mental health of 94 Norwegian-born children from a community cohort of Vietnamese refugees, aged 4 - 18 years, with that of a Norwegian community sample.</p> <p>Methods</p> <p>The SDQ was completed by two types of informants; the children's self-reports, and the parents' reports, for comparison with Norwegian data from the Health Profiles for Children and Youth in the Akershus study.</p> <p>Results</p> <p>The self-perceived mental health of second-generation Vietnamese in Norway was better than that of their Norwegian compatriots, as assessed by the SDQ. In the Norwegian-Vietnamese group, both children and parents reported a higher level of functioning.</p> <p>Conclusion</p> <p>This surprising finding may result from the lower prevalence of mental distress in Norwegian-Vietnamese children compared with their Norwegian peers, or from biased reports and cultural differences in reporting emotional and behavioural problems. These findings may represent the positive results of the children's bi-cultural competencies.</p

The mental health of populations directly and indirectly exposed to violent conflict in Indonesia

Background Large disasters affect people who live both near and far from the areas in which they occur. The mental health impact is expected to be similar to a ripple effect, where the risk of mental health consequences generally decreases with increasing distance from the disaster center. However, we have not been able to identify studies of the ripple effect of man-made disaster on mental health in low-income countries. Objectives The objective was to examine the hypothesis of a ripple effect on the mental health consequences in populations exposed to man-made disasters in a developing country context, through a comparison of two different populations living in different proximities from the center of disaster in Mollucas. Methods Cross-sectional longitudinal data were collected from 510 Internally Displaced Persons (IDPs) living in Ambon, who were directly exposed to the violence, and non-IDPs living in remote villages in Mollucas, Indonesia, who had never been directly exposed to violence in Mollucas. Data were collected during home visits and statistical comparisons were conducted by using chi square tests, t-test and logistic regression. Results There was significantly more psychological distress "caseness" in IDPs than non-IDPs. The mental health consequences of the violent conflict in Ambon supported the ripple effect hypothesis as displacement status appears to be a strong risk factor for distress, both as a main effect and interaction effect. Significantly higher percentages of IDPs experienced traumatic events than non-IDPs in all six event types reported. Conclusions This study indicates that the conflict had an impact on mental health and economic conditions far beyond the area where the actual violent events took place, in a diminishing pattern in line with the hypothesis of a ripple effect

Perceived discrimination is associated with severity of positive and depression/anxiety symptoms in immigrants with psychosis: a cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Immigration status is a significant risk factor for psychotic disorders, and a number of studies have reported more severe positive and affective symptoms among immigrant and ethnic minority groups. We investigated if perceived discrimination was associated with the severity of these symptoms among immigrants in Norway with psychotic disorders.</p> <p>Methods</p> <p>Cross-sectional analyses of 90 immigrant patients (66% first-generation, 68% from Asia/Africa) in treatment for psychotic disorders were assessed for DSM-IV diagnoses with the Structured Clinical Interview for DSM Disorders (SCID-I, sections A-E) and for present symptom severity by The Structured Positive and Negative Syndrome Scale (SCI-PANSS). Perceived discrimination was assessed by a self-report questionnaire developed for the Immigrant Youth in Cultural Transition Study.</p> <p>Results</p> <p>Perceived discrimination correlated with positive psychotic (r = 0.264, p < 0.05) and depression/anxiety symptoms (r = 0.282, p < 0.01), but not negative, cognitive, or excitement symptoms. Perceived discrimination also functioned as a partial mediator for symptom severity in African immigrants. Multiple linear regression analyses controlling for possible confounders revealed that perceived discrimination explained approximately 10% of the variance in positive and depression/anxiety symptoms in the statistical model.</p> <p>Conclusions</p> <p>Among immigrants with psychotic disorders, visible minority status was associated with perceived discrimination and with more severe positive and depression/anxiety symptoms. These results suggest that context-specific stressful environmental factors influence specific symptom patterns and severity. This has important implications for preventive strategies and treatment of this vulnerable patient group.</p

Post-traumatic stress disorder moderates the relationship between trauma exposure and chronic pain

Background: Trauma exposure and post-traumatic stress disorder (PTSD) are risk factors for chronic pain. Objective: This study investigated how exposure to intentional and non-intentional traumatic events and PTSD are related to pain severity and outcome of treatment in chronic pain patients. Methods: We assessed exposure to potentially traumatizing events, psychiatric diagnosis with structured clinical interview, and pain severity in 63 patients at a secondary multidisciplinary pain clinic at the beginning of treatment, and assessed level of pain at follow up. Exposure to potentially traumatizing events and PTSD were regressed on pain severity at the initial session and at follow up in a set of multiple regression analysis. Results: The participants reported exposure to an average of four potentially traumatizing events, and 32% had PTSD. Exposure to intentional traumatic events and PTSD were significantly associated with more severe pain, and PTSD significantly moderated the relationship between trauma exposure and pain (all p < .05). The treatment programme reduced pain moderately, an effect that was unrelated to trauma exposure and PTSD. Conclusions: Trauma exposure is related to chronic pain in the same pattern as to mental disorders, with intentional trauma being most strongly related to pain severity. PTSD moderated the relationship between trauma exposure and pain. While pain patients with PTSD initially report more pain, they responded equally to specialist pain treatment as persons without PTSD
