Objective: To examine to which extent 9 items pertaining to health perception fulfil the Likert criteria for adding the scores for each item to make up a Current Health scale. The term "scaling" denotes the process of constructing a scale from questionnaire items.
Design: Examination of convergent and discriminant validity of items, groupings of items, item variance, and information content of each item.
Subjects: 2,263 male and female heads of households who participated in The Danish Health Study 1982-83. The survey used items pertaining to health status from Rand's Health Insurance Study.
Results: The Likert criteria for constructing a scale of the nine items are fulfilled except for one item. The lack of fulfillment for this item can eventually be attributed to the translation.
