DHP | R Documentation |
The DHP is a multidimensional patient self-completion diabetes-specific inventory designed to identify psychosocial dysfunction among adult insulin dependent and insulin requiring patients. Factor analyses have suggested that responses to DHP items depend on three latent variables representing Psychological distress, Barriers to Activity and Disinhibited eating. Chwalow et.al (2007) describe a randomized study of the quality of life of type 2 diabetic patients.
data(DHP)
A data frame with 185 rows and 8 variables.
The Disinhibited eating (DE) subscale summarizing responses to the following five questions with four ordinal response categories that were coded in such a way that 0 represents no dysfunction and 3 represents a high degree of dysfunction:
Do you wish there were not so many things to eat? Responses: a) “Not at all”, b) “A little”, c) “A lot”, d) “Very much”
