Psychometric properties of the Developmental Tasks Questionnaire for Seniors

Abstract

The study describes the development of the Developmental Tasks Questionnaire for Seniors (DTQ-S), intended for assessing the level of developmental tasks attainment in old age, and evaluates its psychometric properties. The study group included 851 people, aged 60–94 years (M = 69.23; SD = 6.86): 540 women (63.5%) and 311 men (36.5%). As a result of the analysis, a 15-item questionnaire comprising three subscales was created: acceptance of one’s life, adaptation, and acceptance of passing. Confirmatory Factor Analysis demonstrated that the model had a satisfactory fit. The Cronbach’s alpha of the overall scale was.81, demonstrating good internal consistency. Preliminary results suggest that the DTQ-S has adequate convergent and divergent validity. The DTQ-S can be a useful tool for understanding the psychological functioning of seniors for content related to adapting to old age.
