Assessment of the psychometric properties of the Scale of Detection of Existential Loneliness in patients with advanced diseases

Abstract

Aim: To analyze the psychometric properties and the clinical utility of the Scale of Existential Loneliness (EDSOL) in hospitalized patients with advanced disease. Method: To determine the psychometric properties of the scale, the EDSOL scale was administered along with other instruments to 103 adult patients with advanced diseases admitted to 5 palliative care units of Catalan hospitals. Results: The scale presents an excellent reliability measured through Cronbach’s alpha (0.902) and adequate temporal stability (r = 0.71). The scale showed positive and significant correlations with anxiety and depression of the HADS scale and with the overall score of HADS, as well as with the clinical psychological assessment (p <0.01). Through the statistical analysis of the ROC curves, it was determined that the scale had a sensitivity of 79.8% and a specificity of 74.6% and it is suggested that the cut-off point for the detection of EDSOL be a score of 5. Conclusions: The EDSOL scale has good psychometric properties, is simple, brief, reliable and easy to administer. We consider that is an useful scale to detect the presence of existential loneliness in hospitalized patients suffering from advanced diseases.
