Construction of a death anxiety scale-extended

A 51-item Death Anxiety Scale-Extended was constructed. This scale consists of the 15 Death Anxiety Scale items plus 36 new items which were generated on a rational basis that both survived content validity ratings and correlated at the .001 level with three out of four groups (one Kuwaiti, one Sudanese, and two American) participants. The Death Anxiety Scale-Extended correlated .81 with the Death Anxiety Scale. The 36 new items (Death Anxiety Scale-New) correlated .64 with the Death Anxiety Scale and .97 with the Death Anxiety Scale-Extended. The Kuder-Richardson formula 20 coefficients of internal consistency were .73 for the Death Anxiety Scale, .91 for the Death Anxiety Scale-New, and .92 for the Death Anxiety Scale-Extended. © 2006, Baywood Publishing Co., Inc.
