The SSAGA Phase 2 study is a selected followup of the SSAGA 1 cohort with a longer instrument.
The version of the SSAGA instrument used in the SSAGA 2 study is known as
the SSAGA-OZ. The SSAGA-OZ is an Australian adaptation of the SSAGA,
incorporating additional sections from other interviews (SIFU, NSHS, and
others). The shorter version of the SSAGA instrument used in the SSAGA 1
study is known as the Mini-SSAGA-OZ.
The SSAGA (Semi-Structured Assessment for the Genetics of Alcoholism) is
an instrument designed to assess physical, psychological and social
manifestations of alcoholism and related disorders. It is a semi- structured
interview which capitalises on prior research in psychiatric epidemiology. As
such, it relies heavily on items previously validated by other research
interviews, including DIS, CIDI, HELPER, SAM, SADS, and SCID.
The members of the COGA Assessment Committee are indebted to the many researchers
who developed the interviews upon which, in part, the SSAGA is based.
In addition to SSAGA2, a different subset of the the SSAGA1 subjects was
followed up with the SSAGA-OZ as part of Pam Madden's ABMRF Interview for
Women study. This involved 521 families of whom 1033 indivisuals were
eligible after removing some subjects due to ACTSTATs.
The SSAGA2 and ABMRF cohorts are completely distinct, ie there are NO
subjects who are in both studies. For this reason
