RESUMO
Background: The coronavirus disease 2019 (COVID-19) outbreak caused worldwide disruptions to healthcare systems. The emerging evidence indicates that mental health problems have consequently become an occupational hazard in frontline healthcare workers. Aim: We aimed to develop a psychological preparedness training (PPT) programme to support frontline health workers in three resource-limited hospitals in South Africa dealing with the COVID-19 outbreak and to evaluate its effectiveness using an audit tool. We established a theoretical framework and goals for a psychological preparedness programme to support healthcare workers at the study sites. Setting: Data were collected at the Dora Nginza Hospital, Nelson Mandela Academic Hospital and Elizabeth Donkin Hospital. Methods: We employed an observational, descriptive, and cross-sectional design. A group psychological intervention was developed and implemented at the three sites in South Africa, from mid-April 2020 over 20 weeks. We collected data using an audit tool to measure healthcare workers' perceptions of the outbreak before and after the intervention. We analysed the data to test for a statistically significant difference between the pre-intervention and post-intervention audit tools. Results: We supported 761 healthcare workers during the 20 weeks of the programme. Statistical analysis showed a significant positive change from pre- to post-intervention measures in perceptions of health worker about the outbreak, their anxiety associated with the outbreak, their ability to control reactions to stress and the perception of their ability to support others. Feedback comments indicated that the programme was beneficial for the majority of those who attended. Conclusion: Health workers who attended the programme reported improvement in stress levels and in perceptions about their ability to cope with the outbreak, as well as in their perceptions of being able to support others.
RESUMO
Background: Trauma exposure is widespread and linked to chronic physical and mental health conditions including posttraumatic stress disorder. However, there are major gaps in our knowledge of trauma exposure in Africa and on the validity of instruments to assess potentially life-threatening trauma exposure.Objective: The Life Events Checklist for the DSM-5 (LEC-5) is a free, widely used questionnaire to assess traumatic events that can be associated with psychopathology. As part of a case-control study on risk factors for psychosis spectrum disorders, we used the LEC-5 to examine the frequency of traumatic events and to assess the questionnaire's factor structure in South Africa (N = 6,765).Method: The prevalence of traumatic events was measured by individual items on the LEC-5 across the study sample, by case-control status, and by sex. Cumulative trauma burden was calculated by grouping items into 0, 1, 2, 3, and ≥4 traumatic event types. Psychometric properties of the LEC-5 were assessed through exploratory and confirmatory factor analyses.Results: More than 92% of the study sample reported experiencing ≥1 traumatic event; 38.7% reported experiencing ≥4 traumatic event types. The most endorsed item was physical assault (65.0%), followed by assault with a weapon (50.2%). Almost 94% of cases reported ≥1 traumatic event compared to 90.5% of controls (p < .001) and 94% of male participants reported ≥1 traumatic event compared to 89.5% of female participants (p < .001). Exploratory factor analysis revealed a 6-factor model. Confirmatory factor analyses of three models found that a 7-factor model based on the South African Stress and Health survey was the best fit (standardized root mean square residual of 0.024, root mean square error of approximation of 0.029, comparative fit index of 0.910).Conclusion: Participants reported very high exposure to traumatic events. The LEC-5 has good psychometric priorities and is adequate for capturing trauma exposure in South Africa.
Trauma exposure was extremely prevalent in this South African sample, with less than 8% of participants reporting zero exposure to traumatic events.This was the first time the factor structure of the LEC-5 was assessed in South Africa.A confirmatory factor analysis using a 7-factor model based on a previous study of trauma exposure, the South African Stress and Health study (SASH), was the best fit for the LEC-5.
