A sample of 59 patients with asthma and chronic obstructive pulmonary
diseases (COPD) was compared to matched samples of psychiatric patient
s and normal individuals with respect to personality disorders (PDs) a
ssessed by a self-report measure (VKP) (Duijsens, Eurelings-Bontekoe,
Diekstra & Ouwersloot, 1993a, b). The number of PDs differed significa
ntly between pulmonary and psychiatric patients, while there was no si
gnificant difference between pulmonary patients and normal individuals
. Comparison of the number of diagnosis criteria yielded significant c
ontrasts between psychiatric patients versus the normal individuals an
d the pulmonary patients. Pulmonary patients and normal individuals sh
owed significantly lower mean number of criteria met than matched psyc
hiatric patients for nearly all of the diagnoses. It is concluded that
PDs are no more prevalent in asthma and COPD patients than in the gen
eral population.
