Criticism by community people and poor workplace communication as risk factors for the mental health of local welfare workers after the Great East Japan Earthquake: A cross-sectional study

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.

Workplace and safety perceptions among New York City employees after the 9/11 attacks

This study examined associations of individual characteristics on perceived workplace conditions and safety in a volunteer sample of 254 employees from businesses in New York City's World Trade Center (WTC) towers and other area workplaces who completed structured diagnostic and disaster-specific interviews an average of 35 months after the September 11, 2001 (9/11) terrorist attacks. WTC workplace employees perceived greater workplace responsiveness to their post-9/11 needs relative to employees of other workplaces, independent of individual demographic and other disaster-related variables; they also reported lower perceived safety at work. Thus, employee disaster-related workplace location, an organizational-level variable, was a powerful determinant of individual perceptions of the postdisaster workplace and its responsiveness, suggesting the importance of organizational disaster planning and response in helping workers adjust to the postdisaster workplace environment and promoting personal healing and recovery.

Trajectories for Post-traumatic Stress Disorder Symptoms Among Local Disaster Recovery Workers Following the Great East Japan Earthquake: Group-based Trajectory Modeling

BACKGROUND

As many local municipality and medical workers were involved in disaster recovery duties following the Great East Japan Earthquake (GEJE) on March 11, 2011, the aim of this work was to elucidate the distinct trajectories for post-traumatic stress disorder (PTSD) symptoms and associated factors among these personnel. They confronted a diverse range of stressors both as survivors and as relief workers; however, little is known about their longitudinal PTSD symptoms.

METHODS

The participants were 745 local municipality and hospital medical workers [average age: 43.6 ± 9.5 years, range: 20 - 66 years; 306 (59%) women] involved in disaster recovery duties following the GEJE. PTSD symptoms were measured using the Japanese version of the PTSD Checklist Specific Version (PCL-S) at four time points: 14, 30, 43, and 54 months after the GEJE. Using group-based trajectory modeling, distinct trajectories were elucidated.

RESULTS

We identified five distinct PTSD symptoms profiles: resistance (n = 467, 62.7%), subsyndromal (n = 181, 24.3%), recovery (n = 47, 6.3%), fluctuating (n = 26, 3.5%), and chronic (n = 24, 3.2%). The trajectories differed according to the post-disaster working conditions and personal disaster experiences.

LIMITATIONS

Potential selection bias resulting from the limited number of participants who completed all waves. The survey was conducted in one region of the disaster area.

CONCLUSIONS

The majority of participants remained stable, with a relatively small group classified as chronic and fluctuating. Our results highlight the importance of improved working conditions and sustained monitoring of workers responding to natural disasters.

The pitfall of empathic concern with chronic fatigue after a disaster in young adults

BACKGROUND

Empathic concern (EC) is an important interpersonal resilience factor that represents positive adaptation, such as "relating to others" (a factor of posttraumatic growth [PTG]) after disaster. However, controversy exists regarding whether the changes in EC (e.g., the intra-personal change between the acute phase and the disillusionment phase) positively or negatively affect mental health after a disaster. We hypothesized that increased EC may increase chronic fatigue due to over-adjustment (hypothesis 1). We also hypothesized that increasing the changes in "relating to others" could decrease the changes in chronic fatigue (hypothesis 2).

METHODS

Forty-nine young, healthy volunteers (M/F: 36/13; age at 3 months after the disaster [3 months]: mean ± SD: 21.1 ± 1.7 years) underwent assessments of EC using the Japanese version of the Interpersonal Reactivity Index, chronic fatigue using the Japanese version of the Checklist Individual Strength (CIS-J) questionnaire, and "relating to others" using the Japanese version of the PTG inventory during the acute phase (3 months) and the disillusionment phase (1 year after the disaster). Pearson product moment correlations at 3 months and 1 year were determined for all scores related to EC. The changes (delta = degree of change from 3 months to 1 year) or scores at 1 year were entered into linear structural equation systems to test the hypotheses.

RESULTS

The delta of EC positively affected the delta of the CIS-J, and the delta of relating to others negatively affected the delta of the CIS-J. Both the EC and relating to others scores were negatively associated with the CIS-J score at 1 year. These results were in accordance with hypothesis 1 and 2.

CONCLUSIONS

We demonstrated the opposite effects of 2 types of ECs, i.e., stability (inherent disposition) and flexibility (degree of change), on the degree of chronic fatigue. Increasing EC with increasing chronic fatigue, but not the change in relating to others, may be a red flag for individuals during the disillusionment phase.

The association between effective workplace communication with superiors and lower psychological distress among workers in the evacuation area after the Fukushima Daiichi Nuclear Power Plant accident

OBJECTIVES

Well-managed workplace communication may promote well-mental health status among workers, even those who may have experienced drastic changes in their workplace and living environment after the Fukushima Daiichi Nuclear Power Plant accident. This study aimed to compare the workplace and living environment of workers in the evacuation area to the non-evacuation area, as well as the association between workplace communication and psychological distress.

METHOD

This cross-sectional questionnaire survey was conducted in two manufacturing companies in the evacuation area and a company in the non-evacuation area. Psychological distress was defined by a Kessler K6 distress scale score ≥5. Workplace communication was measured by the status of communication ("Do you feel that you can talk freely?") and consultation ("Can you consult when having troubles?") with superiors, managers and colleagues. Work burden, overtime, and irregular mealtimes as changes in the workplace and domestic life were determined. Differences in the workplace and living environment were compared using the chi-squared test, with the association between workplace communication and psychological distress analyzed by logistic regression.

RESULTS

The proportion of workers with an increased work burden, overtime, and irregular meals was significantly higher among workers in the evacuation areas. There was also a significant association between low-psychological distress status and communication and consultation with superiors or managers, with no significant association with colleagues.

CONCLUSION

Only workplace communication with superiors or managers was associated with low-psychological distress, even after drastic changes in the workplace. Therefore, superiors or managers should initiate open communication and active consultation after a disaster.

Addressing challenges in children's mental health in disaster-affected areas in Japan and the Philippines - highlights of the training program by the National Center for Global Health and Medicine

Background and purpose

Natural disasters such as earthquakes, typhoons, floods, and volcanic eruptions frequently occur in Republic of Philippines and mental health care for children affected by these natural disasters is a major public health concern. Aiming to train health professionals on children’s mental health, to conduct a situational analysis to identify the local needs and resources for children’s mental health, and to propose a mental health program for children that can be transferred from Japan to the Philippines, the National Center for Global Health and Medicine (NCGM) conducted a training program for children’s mental health in disaster-affected areas in Japan and the Philippines in June, October, and December, 2017. The training was organized by NCGM for the Program for International Promotion of Japan’s Healthcare Technologies and Services funded by Ministry of Health, Labour, & Welfare, Japan in relation to the Memorandum of Understanding in the Field of Healthcare between NCGM in Japan and University of the Philippines Manila, College of Public Health.

Key highlights

The training program consisted of classroom trainings, site visits, and round table discussions in Japan and the Philippines. The classroom trainings and site visits focused on two points: the experiences of individuals and families who survived the Great East Japan Earthquake (GEJE) in 2011 and super typhoon Haiyan in 2013 and the program and activities, especially on mental health, of various government and non-government organizations in helping the affected families and communities. The round table discussion, on the other hand, was conducted to identify challenges related to children’s mental health in disaster-affected areas and to develop recommendations to address these challenges.

The major recommendations for the Philippines were to give equal emphasis to physical and psychosocial preparedness and to develop a comprehensive program to care for carers. In Japan, public health and mental health should be integrated in the Disaster Medical Service. Experts from both countries should also generate evidence on the effectiveness of interventions in reducing mental health stigma and collaborate with school personnel and communities in order to learn more about psychosocial preparedness. Finally, mental health must be mainstreamed in programs not only in Japan but also in other countries.

Implications

The training program enabled key stakeholders to describe the current situation of mental health in Japan and the Philippines, to identify mental health challenges common to disaster-affected areas in both countries, and to propose short- and long-term plans and recommendations. The training program is expected to address the mental health needs of children in disaster-affected areas through a responsive community-based support network. The training participants agreed to form a network and build partnerships toward the common goal of mainstreaming community-based support for children’s mental health in disaster-affected areas in Japan and the Philippines.
