Aims

  • To evaluate the psychometric properties of the DSM-IV mania symptoms in an epidemiologic sample - first investigation of its kind in Australia and
    only second internationally.
  • Since mania frequently co-occurs with substance use disorders (SUD), to examine differences in symptom expression between those mania respondents with and without a lifetime SUD.
