Little is known about whether and to what extent loneliness impacts the lives of people with visual impairment (VI). Thus, the aim of this study was to examine the prevalence of and factors associated with loneliness in adults with VI, and to examine its association with life satisfaction. This cross-sectional interview study included a probability sample of 736 adults (≥18 years old) with VI who were members of the Norwegian Association of the Blind and Partially Sighted. The interviews took place from January to May 2017, collecting information about sociodemographics, VI characteristics, adverse life events, loneliness (Three Item Loneliness Scale), and life satisfaction (Cantril’s Ladder of Life Satisfaction). The prevalence of loneliness was compared to data obtained from the general Norwegian population (N = 14,884; mean age 46.4 years; 50.7% females). The prevalence of moderate and severe loneliness in the VI population was 28.7% (95% CI: 25.4, 32.1) and 19.7% (95% CI: 16.9, 22.8), respectively. The rates were consistently higher across age groups compared to the general population. Loneliness was associated with younger age, blindness, having other impairments, unemployment, and a history of bullying or abuse. In addition, higher scores on loneliness were associated with lower levels of life satisfaction (fully adjusted β = − 0.48, 95% CI: − 0.55, − 0.41). Loneliness is common in adults with VI. Strategies capable of reducing loneliness could improve life satisfaction among people who are blind or visually impaired.

Psychiatric outpatients with a refugee background have often been exposed to a variety of potentially traumatizing events, with numerous negative consequences for their mental health and quality of life. However, some patients also report positive personal changes, posttraumatic growth, related to these potentially traumatic events. This study describes posttraumatic growth, posttraumatic stress symptoms, depressive symptoms, post-migration stressors, and their association with quality of life in an outpatient psychiatric population with a refugee background in Norway.

This population-based study assessed the prevalence and determinants of symptom-defined post-traumatic stress disorder (PTSD) in a cohort of hospitalized and non-hospitalized patients about 1.5–6 months after their COVID-19 onset. The data were acquired from two mixed postal/web surveys in June–September 2020 from patients all aged ≥18 years with a positive polymerase chain reaction for severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) until 1 June 2020, comprising both hospitalized and non-hospitalized subjects. The catchment areas of the two included hospitals covers about 17% of the population of Norway. In total, 211 hospitalized and 938 non-hospitalized subjects received invitation. The prevalence of symptom-defined PTSD was assessed using the PTSD checklist for DSM-5 (PCL-5). Determinants of symptom-defined PTSD and PTSD symptoms were analyzed using multivariable logistic and linear regression analysis. In total, 583 (51%) subjects responded at median 116 (range 41–200) days after COVID-19 onset. The prevalence of symptom-defined PTSD was 9.5% in hospitalized and 7.0% in non-hospitalized subjects (p = 0.80). Female sex, born outside of Norway, and dyspnea during COVID-19 were risk factors for persistent PTSD symptoms. In non-hospitalized subjects, previous depression and COVID-19 symptom load were also associated with persistent PTSD symptoms. In conclusion, COVID-19 symptom load, but not hospitalization, was associated with symptom-defined PTSD and PTSD symptom severity.

Traumatized refugees often report significant levels of chronic pain in addition to posttraumatic stress disorder symptoms, and more information is needed to understand pain in refugees exposed to traumatic events. This study aimed to assess the frequency of chronic pain among refugee psychiatric outpatients, and to compare outpatients with and without chronic pain on trauma exposure, psychiatric morbidity, and psychiatric symptom severity. We conducted a cross-sectional study of sixty-one psychiatric outpatients with a refugee background using structured clinical diagnostic interviews to assess for traumatic events [Life Events Checklist (LEC)], PTSD (Posttraumatic Stress Disorder) and complex PTSD [Structured Clinical Interview for DSM-IV PTSD Module (SCID-PTSD) and Structured Interview for Disorders of Extreme Stress (SIDES)], chronic pain (SIDES Scale VI) and psychiatric symptoms [M.I.N.I. International Neuropsychiatric Interview (M.I.N.I.)]. Self-report measures were used to assess symptoms of posttraumatic stress [Impact of Event Scale-revised (IES-R)], depression and anxiety [Hopkins Symptom Checklist (HSCL-25)] and several markers of acculturation in Norway. Of the 61 outpatients included, all but one reported at least one chronic pain location, with a mean of 4.6 locations per patient. Chronic pain at clinical levels was present in 66% of the whole sample of outpatients, and in 88% of the outpatients with current PTSD diagnosis. The most prevalent chronic pain locations were head (80%), chest (74%), arms/legs (66%) and back (62%). Women had significantly more chronic pain locations than men. Comorbid PTSD and chronic pain were found in 57% of the outpatients. Significant differences were found between outpatients with and without chronic pain on posttraumatic stress, psychological distress, and DESNOS severity. Chronic pains are common in multi-traumatized refugees in outpatient clinics in Norway, and are positively related to symptomatology and severity of psychiatric morbidity. The presence of chronic pain, as well as comorbid chronic pain and PTSD, in psychiatric outpatients with a refugee background call for an integrated assessment and treatment for both conditions.

Background: Post-traumatic stress disorder (PTSD) diagnosis often depends on a retrospective, self-report of exposure to a life-threatening event.Aims: To examine the stability of recalled perceived life threat in a community sample exposed to a distinct stressful event.Method: Five hundred and thirty-two Norwegian citizens who experienced the 2004 South-East Asia tsunami completed a self-report questionnaire 6 and 24 months post-disaster. The questionnaire measured perceived life-threat intensity, exposure, immediate stress response, psychopathology, personality dimensions, self-efficacy and social support.Results: Recalled threat intensity increased from 6 to 24 months (P<0.001). Recall amplification was associated with lack of PTSD symptom improvement (P< 0.05), but not with degree of exposure, immediate stress response, mood or stress symptoms, personality, self-efficacy or social support.Conclusions: Recall amplification of perceived life threat from a single stressful event occurs in the general population, it may hinder PTSD symptom improvement and it questions the diagnostic validity of PTSD.
