About Attitudes to Ageing Questionnaire
The AAQ was designed for completion by older people themselves and was developed following a robust psychometric procedure piloted with 1356 older people in 15 centres across the world and later field-tested with 5566 older people in 20 centres across the globe (including centres in Eastern and Western Europe, Asia (China and Japan) and North and South America). The mean age of the field trail sample was 72.53 (SD: 7.90). Almost 90% of the opportunistic sample lived in their own home or with family members. The 24 items of the AAQ scale are scored on a five-point Likert scale (1 = strongly disagree, 5 = strongly agree).
The development of this AAQ followed a coherent, logical and empirical process taking full account of the contemporary gerontological theory and both modern and classical psychometric analytical methods. Exploratory factor analysis combined with an Item Response Theory approach using Rasch analysis was used in determining three distinct subscales for the AAQ: (1) Psychosocial Loss; (2) Physical Change; and (3) Psychological Growth. Each domain includes eight items. The three subscales of the AAQ report reasonably good PSI (Person Separation Index) scores of .807, .809 and .738 respectively. The PSI score is a summary estimate of the true variance relative to the sum of this variance and the error variance. It is used as a reliability index for Item Response Theory (IRT) equivalent to Cronbach’s alpha.
