A systematic review of the psychometric properties of death anxiety self-report measures

Abstract

Recent research suggests that the transdiagnostic construct of death anxiety may be a basic fear underlying a range of anxiety disorders. Although the investigation of death anxiety in clinical populations is relatively recent, the death anxiety literature as a whole has a longer history evidenced by the number of instruments developed to measure this construct. This systematic review aimed to evaluate the evidence supporting the psychometric properties of self-report death anxiety measures. Relevant studies were identified via a systematic search of four electronic databases in addition to reference list searches. Two independent reviewers evaluated relevant studies using the established Terwee et al. quality appraisal tool. Of the 1831 studies identified, 89 met inclusion criteria. These studies investigated the psychometric properties of 21 self-report scales of death anxiety as well as six subscales. No measure was found to possess evidence of adequacy on all evaluated quality criteria. The Templer Death Anxiety Scale, Concerns about Dying Instrument and Death Concern Scale were found to possess the most evidence supporting their validity and reliability. Overall findings suggest that additional research is needed to establish the psychometric adequacy of death anxiety instruments, especially given increased utilization of these measures in both clinical and research settings.
