Objective
This study examined relationships among family history of alcohol,
drug, and psychiatric problems and substance use severity, interpersonal
relationships, and service use in individuals with dual diagnosis.
Methods
Data were collected with the family history section of the Addiction
Severity Index administered as part of three studies of individuals with
dual disorders (N=413). Participants were categorized into
family history risk groups for each problem domain based on the number of
first and second degree relatives with alcohol, drug, or psychiatric
problems.
Results
Rates of alcohol, drug, and psychiatric problems were high across
family member categories and highest overall for siblings. Over two-thirds
of the sample was categorized in the high-risk group in the alcohol problem
domain, almost half of the sample was categorized as high-risk in the drug
problem domain, and over a third of the sample was categorized as high-risk
in the psychiatric problem domain. Across problem domains, individuals in
the high-risk group reported more relationship problems with parents and
siblings and higher rates of lifetime emotional, physical, and sexual abuse
than did those in the low or moderate-risk groups.
Conclusions
Family history of alcohol, drug, and psychiatric problems is
associated with greater rates of poor family relationships and history of
abuse. Assessment of these different forms of family history in multiple
family members can aid treatment providers in identifying individuals with
dual disorders who may benefit from trauma-informed care as part of their
overall mental health and substance abuse treatment services.
