Although psychosocial problems are commonly associated with
both alcohol misuse and insomnia, very little is known about the combined
effects of insomnia and current alcohol dependence on the severity of
psychosocial problems. The present study evaluates whether the co-occurrence of
insomnia and alcohol dependence is associated with greater psychosocial problem
severity.
Alcohol dependent individuals (N = 123) were evaluated prior
to participation in a placebo-controlled medication trial. The Short Index of
Problems (SIP), Addiction Severity Index (ASI), Insomnia Severity Index (ISI),
and Time Line Follow Back (TLFB), were used to assess psychosocial, employment,
and legal problems; insomnia symptoms; and alcohol consumption, respectively.
Bivariate and multivariate analyses were used to evaluate the relations between
insomnia and psychosocial problems.
Subjects' mean age was 44 years (SD = 10.3), 83% were male,
and their SIP sub-scale scores approximated the median for normative data. A
quarter of subjects reported no insomnia; 29% reported mild insomnia; and 45%
reported moderate-severe insomnia. The insomnia groups did not differ on
alcohol consumption measures. The ISI total score was associated with the SIP
total scale score (β = 0.23, p = 0.008). Subjects with moderate-severe insomnia
had significantly higher scores on the SIP total score, and on the social and
impulse control sub-scales, and more ASI employment problems and conflicts with
their spouses than others on the ASI.
In treatment-seeking alcohol dependent subjects, insomnia
may increase alcohol-related adverse psychosocial consequences. Longitudinal
studies are needed to clarify the relations between insomnia and psychosocial
problems in these subjects.
