This study examined reliability and validity of Wisdom-Related Knowledge Assessment, Japanese version.Spontaneous think-aloud responses to wisdom-related dilemmas, in both life-planning and life-review tasks,from 197 adult, young- and old-elderly, were scored on five criteria of wisdom: factual knowledge, procedural knowledge, life-span contextualization, value-goal relativism, and recognition and management of uncer- tainty. Results were as follows: l) Inter-rater agreement indicated an acceptable level of reliability. 2) As expected, nve criteria of wisdom-related knowledge had moderate correlations with each other. 3) With intelligence, social intelligence, and years of education as external criteria, wisdom-related knowledge and wisdom shown in life-planning tasks was signincantly related to years of education. Higher correlation coeffients for wisdom-related scales were found with social intelligellce than with intelligence. These results indicated sufficient validity in life-planning tasks. And 4) some of wisdom-related knowledge and wisdom shown in life-review tasks showed correlations with intelligence or social intelligence, and therefore, demon- strated their validity to a certain extent.
Key words: wisdom, wisdom-related knowledge, adulthood, elderly
