Psychological distress (K6) - adults by age group

    Chart

    Psychological distress (K6), ACT residents, 18+ years, by age group, ACTGHS 2019

    The Kessler 6 (K6) scale was developed to discriminate cases of serious mental illness from non-cases (https://www.hcp.med.harvard.edu/ncs/k6_scales.php).

    Based on their K6 score, 6.5% of 25-44 year olds, 5.3% of 45-64 years olds and 3.3% of 65-80 year olds have probable serious mental illness.

    Note: Probable serious mental illness is based on a score of 19-30. This corresponds with the score categorisation used by the Australian Bureau of Statistics. For more information, visit: https://www.abs.gov.au/ausstats/abs@.nsf/Lookup/4817.0.55.001Chapter92007-08.

    The indicator shows self-reported data collected through Computer Assisted Telephone Interviewing (CATI). Estimates were weighted to adjust for differences in the probability of selection among respondents and were benchmarked to the estimated residential population using the latest available Australian Bureau of Statistics population estimates.

    Respondents to the 2019 ACT General Health Survey were aged 18 years and over. 

    If a respondent was missing one value, the missing value was replaced with the mean of the five non-missing values. If a respondent was missing more than one value, they were excluded from analysis.

    The estimates for males and 65-80 year olds has a relative standard error of 25% to 50% and should be used with caution.

    The estimates for 18-24 year olds and over 80 year olds have been withheld due to small numbers in these groups.

    The Medical Subject Headings (MeSH) approach to grouping age has been used for analysis.
