Posttraumatic stress symptoms in people exposed to the 2017 earthquakes in Mexico

Post-Traumatic Stress Disorder after the 6.1 Magnitude Earthquake in Piura, Peru: A Cross-Sectional Study

In Peru, major disasters like the 2007 Pisco earthquake have produced high rates of post-traumatic stress. However, evidence is still needed to strengthen interventions. In 2021, a major earthquake struck Piura, in northern Peru. In this context, we aimed to assess the prevalence of PTSD and its associated factors. A cross-sectional study was conducted during August-September 2021 in people who experienced the 6.1 Piura earthquake on 30 July 2021. The questionnaire included the PCL-C, CD-RISC, ISI, HFIAS, and additional demographic data. Generalized linear models were used. The prevalence of PTSD was 20.3%. Household income was between PEN 2001 and 3000 (PR = 4.26, 95% CI: 1.08-16.75), smoking (PR = 2.49, 95% CI: 1.03-6.01), experience of a nervous breakdown (PR = 1.83, 95% CI: 1.09-3.09), moderate food insecurity (PR = 2.91, 95% CI: 1.10-7.73), and severe insomnia (PR = 8.25, 95% CI: 2.22-30.71) increased the prevalence of PTSD. One out of five individuals experienced post-traumatic stress symptoms after the 2021 earthquake in Piura, which varies depending on socioeconomic, psychosocial, and individual factors. Further research should strengthen these findings to ensure a fair and early mental health intervention against new seismic events in this and other Peruvian regions.

Measuring mental health burden in humanitarian settings: a critical review of assessment tools

BACKGROUND

The effects of disasters and conflicts are widespread and heavily studied. While attention to disasters' impacts on mental health is growing, mental health effects are not well understood due to inconsistencies in measurement.

OBJECTIVE

The purpose of this study is to review mental health assessment tools and their use in populations affected by disasters and conflicts.

METHOD

Tools that assess posttraumatic stress disorder, depression, substance use disorder, and general mental health were examined. This review began with a search for assessment tools in PubMed, PsycINFO, and Google Scholar. Next, validation studies for the tools were obtained through snowball sampling. A final search was conducted for scientific studies using the selected tools in humanitarian settings to collect the data for analysis. The benefits and limitations described for each tool were compiled into a complete table.

RESULTS

Twelve assessment tools were included, with 88 studies using them. The primary findings indicate that half of the studies used the Impact of Events Scale-Revised. The most common limitation discussed is that self-report tools inaccurately estimate the prevalence of mental health problems. This inaccuracy is further exacerbated by a lack of cultural appropriateness of the tools, as many are developed for Western contexts.

CONCLUSION

It is recommended that researchers and humanitarian workers reflect on the effectiveness of the mental health assessment tool they use to accurately represent the populations under study in emergency settings. In addition, mental health assessment should be coupled with action.

Efficacy of an Early Cognitive-Behavioral Intervention for Acute Stress Disorder in Mexican Earthquake Victims

Acute stress disorder (ASD) refers to the symptoms associated with posttraumatic stress disorder (PTSD) within the first four weeks following the traumatic event. Recent theoretical models suggest that early detection of ASD provides an opportunity to implement early interventions to prevent the development of PTSD or ameliorate its symptomatology. The aim of the present study was the evaluation of the efficacy of an ASD treatment for earthquake victims, which would serve as an early intervention for PTSD. A single-case (n = 1) quasi-experimental design was used, with pre and post-assessments, as well as one, three and six-month follow-ups, with direct treatment replications. Fourteen participants completed the treatment and the follow-up measurements. The results obtained using a single-case analysis showed significant clinical improvement and clinically significant change when employing a clinical significance analysis and the reliable index of change. Statistical analyses of the dataset displayed statistically significant differences between the pre and post-assessments and the follow-up measures, as well as large effect sizes in all clinical measures. These results suggest that the treatment was an efficacious early intervention for PTSD during the months following the traumatic event, although some relevant study limitations are discussed in the text.

Ecological Disasters and Mental Health: Causes, Consequences, and Interventions

Ecological disasters highlight the importance of understanding natural disasters as they relate to a changing global climate. Such disasters often have a predictable pattern of evolving over time and anticipated psychological and behavioral problems and community disruptions. Various factors enhance transmission of these adverse effects beyond the geographic location of the ecological disaster, with certain populations being particularly vulnerable to these effects. Understanding the range and pattern of these effects can aid in optimizing interventions. The use of evidence-informed interventions can reduce distress, enhance well-being, and improve functioning for affected individuals and communities. Effective preparedness involves an understanding of these factors, incorporation of them at all stages of disaster management, and continuous education and training for disaster planners and responders.
