摘要：With the aim of verifying the suitability of the CES-D scale for use in long-term care institutions for older adults,the CES-D questionnaire was used to collect patient-reported assessments,and two well-known psychometric instruments – the Hospital Anxiety and Depression Scale (HADS) and the Barthel Index of Abilities of Daily Living – were used to collect nurse-reported assessments,based on observations of patients’ behaviours. With regard to possible frequent cases of cognitive impairment and/or insufficient motivation to give sensible responses to CES-D questions,the patient-reported responses were collected from patients during one-on-one sessions with a nurse. The reliability, concurrent validity,and the trustworthiness of the obtained data were supported with proper values of the Cronbach’s alpha coefficient,0.70 < alpha < 0.85, with significant correlation between CES-D and HADS-Depression,R = 0.50, p < 0.001,and with significant correlation between scores of particular CES-D items vs. final CES-D evaluations of depression,proved by significance p < 0.001 for 18 of 20 CES-D items. These findings supported the effectiveness of the oneon-one session methodology in questionnaire surveys for older adults. The postulation that cases of self-reported depression included somewhat different information about the patient than nurse-reported depression concerning the same patient was supported with the evidence that,in spite of the significant correlation between the Barthel Index and HADS-Depression,R = –0.17,p = 0.016, and in spite of the significant correlation between CES-D and HADS-Depression, the correlation between the Barthel Index and CES-D,equal to R = –0.08 was insignificant at p = 0.244. The findings of this study,considered jointly,support the valuableness of the CES-D scale for use in one-on-one surveys for older adults.
