This study has certain limitations that must be considered
when analyzing the results. Although we included all patients
who initiated treatment or re-treatment in a reference service
during a time period of almost two years, the sample size is
relatively small and may have led to type 2 error. A standardized
instrument was not used to investigate social support, and no
diagnostic interview was used to evaluate depressive disorders;
depressive symptoms were only evaluated according to the
BDI. Finally, causal relations cannot be assumed due to the
cross-sectional design.
The impact of HCV is evengreater when it is associated with psychiatric disorders, such
as depression and alcohol and/or drug abuse
