Disaster Exposure

Although natural disasters sometimes strengthen community ties, it was hypothesized that the negative affect following a hurricane would lower evaluations of strangers. This hypothesis was tested by having 105 students evaluate an individual that they had just met following Hurricane Andrew. The hypothesis did not receive support, but students living in storm-damaged neighborhoods expressed more negative affect than those living in less damaged neighborhoods. Regression analyses also disclosed that severity of a disaster predicted concentrations of immunoglobulin A in saliva. The results suggest that salivary immunoglobulin A can be used to assess the health consequence of disaster exposure.

Salivary Immunoglobulin A

While research indicates that high stress may be immunosuppressive, little is known about the effects of relaxation on the immune system. To determine whether relaxation is immunoenhancing, 50 volunteer college students were randomly assigned to one of four relaxation methods (Benson's relaxation response, guided visualization, massage, lying quietly with eyes closed, or a touching-control group). Salivary immunoglobulin A (S-IgA) and salivary Cortisol levels were recorded before and after one 20-min. relaxation session. Subjects in the relaxation response, visualization, and massage groups showed a significant increase in S-IgA concentrations from the before to the after relaxation samples. Also, post-relaxation S-IgA concentrations were significantly higher in the relaxation response, visualization, and massage groups than in the touching-control group. Salivary Cortisol did not change significantly. These data suggest that one component of the immune system, S-IgA, may be enhanced by the practice of a coping skill such as relaxation.

Abstract Objectives The extent to which the COVID-19 pandemic is appraised as a stressor influences perceived stress (PS) and psychological well-being during the event. Here, the association of older adults’ expectations concerning the pandemic’s duration and impact with PS and negative affect (NA) is investigated. Based on the stress and coping framework, PS is expected to mediate the association between COVID-19 expectations and NA. Methods Seven hundred fourteen residents of the United States and aged 60 and older completed an anonymous online survey in late March 2020 reporting PS, NA, and expectations regarding the pandemic. Results Regression analyses controlling for demographic factors revealed that more dire pandemic expectations significantly predicted PS and NA directly, and the effects on NA were significantly mediated by PS. Discussion Findings provide evidence that expectations about a pandemic influence the extent to which older adults experience stress and NA in the midst of a pandemic event. Implications for mental health are discussed.
