Jp. Davis et al., DEPRESSION IN ADULTS WITH INTELLECTUAL DISABILITY .2. A PILOT-STUDY, Australian and New Zealand Journal of Psychiatry, 31(2), 1997, pp. 243-251
Objectives: To identity adults with intellectual disability (ID) with
a depressive disorder referred to a tertiary consultation clinic for p
sychiatric assessment; to investigate common presenting features of de
pression in adults with ID; to assess the utility of visual analogue s
cale (VAS) measures of emotion/behaviour, the CORE measure of psychomo
tor disturbance, and substitutive diagnostic criteria in the assessmen
t of depressive disorders in this patient group.Method: Over a 6-month
period 47 patients were seen for psychiatric evaluation. Patients in
whom a diagnosis of depression was made were further assessed using: V
AS measures of depression, irritability, verbal aggression, physical a
ggression, temper outbursts, regressed behaviour; CORE measure of psyc
homotor disturbance; and substitutive diagnostic criteria designed by
the authors. Results: Ten patients were found to have a depressive dis
order. Substitutive criteria resulted in a greater rate of diagnosis t
han standard DSM-IV criteria. The VAS measure of irritability was high
ly scored for all 10 depressed patients. All 10 depressed patients wer
e assigned to the melancholic subgroup according to CORE score. Conclu
sions: Standard assessment measures and diagnostic criteria may requir
e modification to enhance their utility in this patient group. Melanch
olic features require further investigation.
