Some studies have shown that older people experience less experiential avoidance and more gratitude when they were compared with younger people (López, 2020). These variables might be important to improve the mental health of older people, especially in crisis situations.Objective:Investigate the relationship between experiential avoidance (EA), gratitude and distress in old people post crisis COVID-19.Methods:A cross-sectional study was carried out. Data from 361 people older than 60 years. The mean age was 68,44 (SD= 5.31), 62.9% were woman. The sample included in the cross-sectional analysis consisted of who provided data on the Acceptance and Action Questionnaire - II (AAQ–II; Bond et al., 2011), Gratitude subscale of the Values in Action Inventory of Strengths-Short Form (Littman-Ovadia, 2015) and Hospital Anxiety and Depression Scale (Zigmond & Snaith, 1983). Pearson´s correlations were used to explore the relationships among study variables including EA, gratitude, and emotional distress. Lineal regression analyses were used to investigate the incremental explained variance in emotional distress according to the main hypotheses. Standardized regression coefficients β were used to determine the relative contribution of these variables.Results:EA and gratitude were negatively correlated (r=-.27; p= <.000). Gratitude and emotional distress were negatively correlated (r=-.30; p= <.000). EA and emotional distress were positive correlated (r=.61; p= <.000). Regression analyses indicated that AAQ-II and gratitude were significant predictors of emotional distress among old people. AAQ-II and gratitude were added. AAQ-II and gratitude were significant predictor of emotional distress R2adj=62.7 % explain the model.Conclusion:EA and gratitude are powerful factors to predict emotional distress in a crisis among older people. EA is an important construct in the understanding of emotional distress. This is an initial step to deep in the process of internal experiences and promoting gratitude can be very beneficial to generate programs to promote mental health in old people.
