This article reports on the investigation of the correlation between the Eu
ropean Addiction Severity Index (EuropASI) and the Childhood Trauma Questio
nnaire (CTQ) among 102 Norwegian drug abusers admitted to treatment. The ai
m of the study is to explore how different types and levels of childhood tr
auma and social and psychiatric factors, medical situation and experienced
family history are interrelated. The study addresses three main questions:
1) What is the prevalence of different kinds of childhood trauma among drug
abusers in treatment? 2) Does type or level of maltreatment in childhood p
redict specific substance abuse problems as adults and/or specific social,
psychiatric and medical problems as adults? 3) Do substance abuse problems
and mental health problems in the primary family predict different types an
d levels of childhood maltreatment? Twenty-five per cent of the total sampl
e was included in the high-level trauma group and 54% in the intermediate-l
evel group. Females had significantly higher scores than males in all types
of childhood trauma. The strongest correlations were found between childho
od trauma and lifetime psychiatric problems and psychiatric status during t
he last 30 days before admission for treatment. More research, and especial
ly prospective studies, is needed to clarify the importance of parents' sub
stance abuse and psychiatric problems in childhood/adolescent compared with
trauma in the client's childhood and the client's current psychiatric stat
us.
