Abstract

BACKGROUND
Means to measure death anxiety, death depression and sense of symbolic immortality with approved validity and reliability does not yet exist in Korea.
METHODS
Existing English questionnaires such as Templer Death Anxiety Scale (TDAS), Death Depression Scale (DDS), Sense of Symbolic Immortaligy Scale (SSIS) were translated into Korean by 5 translators, and then reviewed by 3 non-participants of translation for collegial summary and this summary was counter-translated again by another 2 non-participants. Another 3 non-participants of translation and counter-translation were chosen to examine the two sentences of each item. Then reexamination was done by retranslating and counter-translating the parts with errors. Aftr pretest on ordinary people. the completed questionnaires were given to medical students, residents and nurses of a university hospital. Pastors and missionaries were selected as comparison group.
RESULTS
Kuder-Richardson or Cronbach-alpha that represent internal consistency of TDAS, DDS and SSIs was 0.69, 0.84 and 0.78. The three sentences that lowered internal consistency of SSIS was deleted. BDI and DDS showed a positive correlation (0.32, P=0.02), suggesting proved construct validity. Correlation coefficient that proves construct validity of TDAS and DDS was 0.54 (P<0.01), of SSIS and TDAS -0.23(P=0.04), of SSIS and DDS -0.29(P=0.01). The TDAS and DDS(P<0.01), DDS and BDI(P=0.02) have shown a positive correlation were shown. There was significant difference in the score of SSIS(P<0.01). The same results in cases where the 3 sentences was deleted.
CONCLUSION
Korean versions of TDAS, DDS and SSIS were reliable and valid.
