S. Weich et al., DO SOCIOECONOMIC RISK-FACTORS PREDICT THE INCIDENCE AND MAINTENANCE OF PSYCHIATRIC-DISORDER IN PRIMARY-CARE, Psychological medicine, 27(1), 1997, pp. 73-80
In a prospective cohort study of consecutive primary care attenders in
south London, the estimated prevalence of non-psychotic psychiatric d
isorder was 45.6%, using the Revised Clinical Interview Schedule (CIS-
R). The estimated 12-month incidence rate was 15.7%. Extremely high st
ability was found in CIS-R scores over 12 months (r = 0.65) and 68.8%
of cases at baseline were also cases 12 months later. A clear differen
ce emerged in the types of risk factor which were associated with the
incidence and maintenance of disorder in the study population: while s
ocioeconomic variables, especially low household income and not having
a partner were associated with a worse outcome among prevalent cases
at baseline, such variables were only weakly associated with the incid
ence of psychiatric disorder after adjusting for potential confounders
. The latter, notably family psychiatric history and the severity of p
sychiatric symptoms at baseline were independently associated with the
incidence of psychiatric disorder after adjusting for other risk fact
ors, including measures of previous psychiatric disorder.
