Abstract
Background. Most studies of spouse similarity for
psychiatric disorders have focused on clinical
samples and are thus limited by selection bias. This study is, to our knowledge,
the first
comprehensive investigation of spouse similarity for lifetime psychiatric
history in a general
population sample using standardized diagnostic criteria.Methods. We studied 519 pairs of spouses residing in Edmonton,
Canada who completed the
Diagnostic Interview Schedule psychiatric interview. In each pair,
one spouse belonged to a random
subsample of persons who had participated in a large population survey
and was re-interviewed.
Association between spouses for lifetime DSM-III psychiatric
disorders was analysed with bivariate
and multivariate logistic regression analyses.Results. We observed significant spousal association for lifetime
presence of affective disorders and
for the spectrum of antisocial personality and addiction
disorders. Antisocial personality in one
spouse was also associated with anxiety disorders in the other
spouse, namely post-traumatic stress
disorder in wives and phobia in husbands; similarly, drug abuse/dependence
in wives was
associated with generalized anxiety in husbands and male drug abuse/dependence
was associated with female post-traumatic stress disorder. Dysthymia in
wives was
associated with generalized anxiety and post-traumatic stress disorder
in husbands.Conclusions. The existence of associations between spouses
for
the presence of psychiatric disorders,
either similar or different, has significant implications for
both clinicians and researchers. Future
research should aim at exploring the aetiological mechanisms of these associations.
