Self-rated health (Table 7.9)


Self-rated health for 12 to 17 years old adolescents in Young-HUNT 1 and four years later in Young-HUNT 2 (Breidablik et al., 2008).

In the HUNT study (Nord-Trøndelag county health survey), one of the questions is: “How is your overall health at the moment?” The outcome categories are “Very good”, “Good”, “Not very good”, and “Poor”. Table 7.9 shows the counts for the adolescents aged 12 to 17 years in 1995 to 1997 (Young-HUNT 1), and for the same individuals four years later (Young-HUNT 2; Breidablik et al. (2008)). Both the rows and the columns are ordered. In this example, it may be appropriate to regard self-rated health as an unobserved (latent) continuous variable, where only a categorized version has been observed. Table 7.9 is actually an example of a paired c × c table with ordinal data.




An object of class matrix (inherits from array) with 4 rows and 4 columns.
