Psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) in 9230 adults across seven European countries: Findings from the ESTSS ADJUST study.

BACKGROUND: The four-item Patient Health Questionnaire-4 (PHQ-4) is a widely used screening measure for depression and anxiety. OBJECTIVES: This study aimed to test factor structure and measurement invariance in an adult sample of the general population across seven European countries. METHOD: A total sample of 9230 adults, 71.3 % female, Mage = 44.35 (SD = 14.11) from seven countries (Austria, Croatia, Georgia, Germany, Lithuania, Portugal, and Sweden) participated in the study. We applied confirmatory factor analysis (CFA) to examine the factor structure and measurement invariance testing to evaluate measurement equivalence across countries, gender, and age groups. RESULTS: The CFA yielded that a two-factor PHQ-4 model with separate depression and anxiety factors had the best fit. Partial scalar measurement invariance was established across different groups based on gender, age, and country. CONCLUSIONS: The PHQ-4 is a valid and reliable measure that can be applied to screen for depression and anxiety in the general population. LIMITATIONS: The limitation of the study includes the sampling, which resulted in the sample structure with the majority of females, predominantly of high education and from urban communities.

Daily uplifts during the COVID-19 pandemic: what is considered helpful in everyday life?

BACKGROUND: Knowledge of what is uplifting and helpful during pandemics could inform the design of sustainable pandemic recommendations in the future. We have explored individuals' views on helpful and uplifting aspects of everyday life during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Participants answered a brief, daily survey via text messages during 14 consecutive days in July-August, 2020. The survey included the question: "During the past 24 hours, is there anything that has made you feel good or helped you in your life?" We used content analysis to compile responses from 693 participants, who provided 4,490 free-text answers, which resulted in 24 categories subsumed under 7 themes. RESULTS: Positive aspects during the COVID-19 pandemic primarily related to social interactions, in real life or digitally, with family, friends and others. Other important aspects concerning work, colleagues and maintaining everyday life routines. One theme concerning vacations, going on excursions and being in nature. Leisure and recreation activities, such as hobbies and physical exercise, also emerged as important, as did health-related factors. Bodily sensations, thoughts, feelings and activities that benefited well-being were mentioned frequently. Lastly, people commented on the government strategies for containing COVID-19, and whether to comply with restrictions. CONCLUSIONS: To summarize, daily uplifts and helpful aspects of everyday life centered around social relationships. To comply with recommendations on physical distancing, people found creative ways to maintain social connections both digitally and face-to-face. Social interaction, maintenance of everyday life routines, hobbies and physical activity appeared to be important for well-being.

Six years after the wave. Trajectories of posttraumatic stress following a natural disaster.

BACKGROUND: The characteristics of long-term trajectories of distress after disasters are unclear, since few studies include a comparison group. This study examines trajectories of recovery among survivors in comparison to individuals with indirect exposure. METHODS: Postal surveys were sent to Swedish tourists, repatriated from the 2004 Indian Ocean tsunami (n=2268), at 1, 3, and 6 years after the tsunami to assess posttraumatic stress (PTS) and poor mental health. Items were used to ascertain high and moderate disaster exposure groups and an indirect exposure comparison group. RESULTS: Long-term PTS trajectories were best characterized by a resilient (72.3%), a severe chronic (4.6%), a moderate chronic (11.2%) and a recovering (11.9%) trajectory. Trajectories reported higher levels of PTS than the comparison group. Exposure severity and bereavement were highly influential risk factors. CONCLUSIONS: These findings have implications regarding anticipation of long-term psychological adjustment after natural disasters and need for interventions after a single traumatic event with few secondary stressors.

Properties of Swedish posttraumatic stress measures after a disaster.

This study evaluated the properties of Swedish versions of self-report measures of posttraumatic stress disorder (PTSD), with emphasis on the Impact of Event Scale-Revised (IES-R). Survey data from adult survivors 1, 3, and 6 years after the 2004 Indian Ocean tsunami (n=1506) included the IES-R (from which the IES-6 was derived) and the 12-item General Health Questionnaire (GHQ-12). The PTSD Checklist (PCL) was included in one survey. A structured clinical interview was performed after 6 years (n=142). Factor analyses of the IES-R and PCL indicated that a dysphoric-arousal model provided good fit invariant across assessments. Both measures were accurate in excluding PTSD while all measures provided poorer positive predictive values. The IES-R, but not the IES-6 and GHQ-12, evidenced stability across assessments. In conclusion, the Swedish IES-R and PCL are sound measures of chronic PTSD, and the findings illustrate important temporal aspects of PTSD assessment.

Impact of physical injury on mental health after the 2004 Southeast Asia tsunami.

BACKGROUND: The risk of developing enduring post-traumatic stress reactions and mental health problems in the aftermath of disasters is substantial. However, there are inconsistencies regarding the contribution of physical injury as an independent risk factor for developing psychiatric morbidity after disasters. AIMS: The aim was to assess whether physical injury was associated with post-traumatic stress reactions and general mental health after adjusting for perceived life-threat in the aftermath of the 2004 tsunami. METHODS: A sample of 1501 highly exposed survivors from the 2004 Southeast Asia tsunami was selected from a cohort of Swedish survivors surveyed 14 and 36 months after the event. The impact of physical injury on post-traumatic stress and general mental health was assessed by regression models accounting for subjective life-threat. RESULTS: Physical injury was associated with higher levels of post-traumatic stress reactions and poorer general mental health. These associations were observed at both 14 and 36 months after the disaster. CONCLUSIONS: Physical injury has a specific contribution to the association between traumatic experience and both post-traumatic stress reactions and general mental health in victims of the 2004 tsunami. The effect is stable over several years.

Prolonged grief among traumatically bereaved relatives exposed and not exposed to a tsunami.

Numerous studies on the mental health consequences of traumatic exposure to a disaster compare those exposed to those not exposed. Relatively few focus on the effect of the death of a close relative caused by the disaster-suffering a traumatic bereavement. This study compared the impact on 345 participants who lost a close relative in the 2004 Indian Ocean tsunami, but who were themselves not present, to 141 who not only lost a relative, but also were themselves exposed to the tsunami. The focus was on psychological distress assessed during the second year after the sudden bereavement. Findings were that exposure to the tsunami was associated with prolonged grief (B = 3.81) and posttraumatic stress reactions (B = 6.65), and doubled the risk for impaired mental health. Loss of children increased the risk for psychological distress (prolonged grief: B = 6.92; The Impact of Event Scale-Revised: B = 6.10; General Health Questionnaire-12: OR = 2.34). Women had a higher frequency of prolonged grief. For men, loss of children presented a higher risk for prolonged grief in relation to other types of bereavement (B = 6.36 vs. loss of partner). Further long-term follow-up could deepen the understanding of how recovery after traumatic loss is facilitated.

Tsunami-exposed tourist survivors: signs of recovery in a 3-year perspective.

Long-term follow-up after disaster exposure indicates increased rates of psychological distress. However, trajectories and rates of recovery in large samples of disaster-exposed survivors are largely lacking. A group of 3457 Swedish survivors temporarily on vacation in Southeast Asia during the 2004 tsunami were assessed by postal questionnaire at 14 months and 3 years after the tsunami regarding post-traumatic stress reactions (IES-R) and general mental health (GHQ-12). There was a general pattern of resilience and recovery 3 years postdisaster. Severe exposure and traumatic bereavement were associated with increased post-traumatic stress reactions and heightened risk for impaired mental health. The rate of recovery was lower among respondents exposed to life threat and among bereaved. Severe trauma exposure and bereavement seem to have considerable long-term impact on psychological distress and appear to slow down the recovery process. Readiness among health agencies for identification of symptoms and provision of interventions might facilitate optimal recovery.

The effect of traumatic bereavement on tsunami-exposed survivors.

Fourteen months after the 2004 tsunami, mental health outcome was assessed in 187 bereaved relatives, 308 bereaved friends, and in 3,020 nonbereaved Swedish survivors. Of the bereaved relatives, 41% reported posttraumatic stress reactions and 62% reported impaired general mental health. Having been caught or chased by the tsunami in combination with bereavement was associated with increased posttraumatic stress reactions. Complicated grief reactions among relatives were almost as frequent as posttraumatic stress reactions. The highest levels of psychological distress were found among those who had lost children. Traumatic bereavement, in combination with exposure to life danger, is probably a risk factor for mental health sequelae after a natural disaster.

Impact of exposure to trauma on posttraumatic stress disorder symptomatology in Swedish tourist tsunami survivors.

The aim was to examine long-term mental health and posttraumatic stress symptomatology in a Swedish tourist population after exposure to the 2004 Southeast Asian tsunami. Data from 4822 returned questionnaires 14 months after the disaster were analyzed. Respondents were categorized into 3 subgroups: (1) danger-to-life exposure group (having been caught or chased by the waves), (2) nondanger-to-life exposure group (exposed to other disaster-related stressors), and (3) low exposure group. Main outcome measures were General Health Questionnaire-12 and Impact of Event Scale-22-Revised. Danger-to-life exposure was an important factor in causing more severe posttraumatic stress symptoms and in affecting mental health. Female gender, single status, and former trauma experiences were associated with greater distress. Other factors related to more severe symptoms were loss of relatives, physical injuries, viewing many dead bodies, experiencing life threat, and showing signs of cognitive confusion. Disaster exposure has a substantial impact on survivors, which stresses the need for long-lasting support.

Psychological effects of serious traumas can cause severe personal suffering for the individual and will also mean a great economical loss för the individual and for the society in terms of decreased functioning due to illness. The Swedish National Center for Disaster Psychiatry has done a survey to investigate the public resources for acute psychosocial support and for treatment of disorders after psychological traumas. The organization of psychosocial support within the public health care system after major disasters is functioning all over Sweden. Twenty-seven clinics were identified. A majority of these clinics have specialized in the support and treatment of victims of war and torture. Fifty percent of the public medical service areas do not have specialist clinics for treatment of trauma related disorders. At many places there is a lack of specialist treatment resources for people who have developed disorders after experiences of assaults, serious accidents or other types of life threats or sudden loss. There is an obvious need of increased resources in this area.
