Results for 2020-2022

Results from the full sample of 15,893 respondents in the National Study of Mental Health and Wellbeing (NSMHW) were published on 5 October 2023 in National Study of Mental Health and Wellbeing, 2020–2022. Readers are directed to these data in preference to results for 2020-21, which were based on a smaller sub-sample of 5,554 respondents.

Revisions to 2020-21 data

Revisions to NSMHW data for 2020-21 are scheduled to be made in late 2023. Results for 2020-21 reported on this page and in the Data downloads section are therefore out of date. Readers are directed to main results published in National Study of Mental Health and Wellbeing, 2020–2022. Revised data for 2020-21 will be available in Microdata: National Study of Mental Health and Wellbeing in late 2023.

Key Statistics

  • Over two in five Australians aged 16-85 years (43.7% or 8.6 million people) had experienced a mental disorder at some time in their life
  • One in five (21.4% or 4.2 million people) had a 12-month mental disorder
  • Anxiety was the most common group of 12-month mental disorders (16.8% or 3.3 million people)
  • Almost two in five people (39.6%) aged 16-24 years had a 12-month mental disorder

COVID-19 context

 

Mental health is a key component of overall health and wellbeing. A mental illness can be defined as ‘a clinically diagnosable disorder that significantly interferes with an individual’s cognitive, emotional or social abilities’[1]. The term itself covers a range of illnesses including anxiety, affective and substance use disorders.

A person does not need to meet the criteria for a mental disorder to be negatively affected by their mental health. Mental ill-health affects and is affected by multiple socioeconomic factors, including a person’s access to services, living conditions and employment status, and impacts not only the individual but also their families and carers.[2]

The ABS recognises people who have a lived experience of mental ill-health and that having - or not having - mental ill-health does not define a person. We acknowledge that people are living productive, purposeful and meaningful lives with mental ill-health. We acknowledge their unique experiences, and those of carers, families and supporters of people living with mental ill-health.

The ABS uses, and supports the use of, the Mindframe guidelines on responsible, accurate and safe reporting on suicide, mental ill-health and alcohol and other drugs. The ABS recommends referring to these guidelines when reporting on statistics in this report.

Some of these statistics may cause distress. Services you can contact are detailed in blue boxes throughout this page and in the Mental health resources section at the bottom of this page.

Type of 12-month mental disorder

12-month Anxiety disorders

Anxiety disorders typically involve feelings of tension, distress or nervousness. A person may avoid situations they believe cause these feelings, potentially limiting their interactions with the wider world and impacting the way they live.[3]

While people’s experiences with affective disorders vary, they can cause a person to withdraw from social contact, lose interest in the important things in their life and make enjoyable activities seem like too much effort.[4][5]

12-month Substance Use disorders

Substance Use disorders involve the harmful use or dependence on alcohol or drugs. While people use substances for a range of reasons, misuse of substances may have serious long-term consequences on a person’s health and wellbeing, as well as negatively impacting families and communities.[6] Substances included in the NSMHW were alcohol and four groups of drugs: sedatives, stimulants, cannabinoids and opioids.

Psychological distress

The Kessler Psychological Distress Scale (K10) is a widely used indicator which gives a simple measure of psychological distress in the past 4 weeks. In 2020-21, 15.4% of Australians aged 16-85 years experienced high or very high levels of psychological distress:

  • Females were more likely to experience high or very high levels of psychological distress than males (18.6% compared with 12.0%)
  • One in five (20.0%) people aged 16-34 years experienced high or very high levels of psychological distress, twice the rate of people aged 65-85 years (9.6%)
  • 64.2% of people with high or very high levels of psychological distress had a 12-month mental disorder.

Lived experience of suicide

Suicidal behaviour is complex, with many influencing factors. Dealing with stressful or traumatic past or present events, death, separation, loss, bullying, mental illness, alcohol and drugs can play a role in causing emotional pain. Other factors may include life-changing events, family history and relationships, work, education, and social pressures.[7]

Suicide can also have a profound emotional effect not only on family and friends, but on the whole community.[8] The ABS acknowledges the individuals, families and communities affected by suicide each year in Australia.

Suicidal thoughts and behaviours in the NSMHW refer to whether a person had ever seriously thought about taking their own life, made a plan to take their own life, or attempted to take their own life, and whether they had done so in the last 12 months.

In 2020-21, one in six (16.7%) Australians aged 16-85 years had experienced any suicidal thoughts or behaviours in their life. This comprises 16.7% of people who had ever seriously thought about taking their own life, 7.7% who had ever made a plan to take their own life, and 4.8% who had ever attempted to take their own life.

  • Females were more likely than males to have experienced any suicidal thoughts or behaviours in their lifetime (18.7% compared with 14.5%)
  • 3.4% of all Australians aged 16-85 years had experienced any suicidal thoughts or behaviours in the last 12 months.
  1. A person must have said they had seriously thought about taking their life to be then asked if they had made a plan or attempt to take their own life. Rates for ‘Any suicidal thoughts or behaviours’ are therefore the same as for ‘Thoughts’.

The NSMHW asked people whether they have ever been close to someone who had taken or attempted to take their own life. Almost two in five (38.0%) people aged 16-85 years had been close to someone who had taken or attempted to take their own life, while 5.9% had been close to someone who had taken or attempted to take their own life in the last 12 months.

Self-harm

Self-harm refers to a person intentionally causing pain or damage to their own body. This behaviour may be motivated as a way of expressing or controlling distressing feelings or thoughts. Self-harm and suicide are distinct and separate acts although some people who self-harm are at an increased risk of suicide.[9]

In 2020-21, 8.8% of Australians aged 16-85 years had ever self-harmed in their lifetime:

  • Females had higher lifetime rates of self-harm than males (11.4% compared with 6.2%)
  • Almost one in four (24.7%) females aged 16-34 years had self-harmed in their lifetime
  • One in fourteen (7.0%) females aged 16-34 years had self-harmed in the last 12 months.
  1. Confidence interval for males not available for publication.

Aspects of disordered eating

Binge eating in the NSMHW is defined as a person eating a large amount of food during a short period of time (more than what most people would eat given the circumstances), associated with feeling this eating is out of control (that is, being unable to prevent these eating behaviours or feeling unable to stop). To be considered binge eating, these behaviours must have occurred at least once a week for several months or longer. These data are not estimates of the prevalence of diagnosed binge eating disorders in Australia, however binge eating and other disordered eating behaviours are the most common indicators of the development of an eating disorder.[10]

The importance of weight and/or shape to how a person thinks of themselves can be a risk factor for the development of eating disorders.[11] In 2020-21, more than one in five people (21.0%) rated their weight and/or shape as being very or extremely important to how they thought about themselves as a person:

  • Females were more likely than males to rate their weight and/or shape as being very or extremely important (24.2% compared with 17.6%)
  • 31.9% of females aged 16-34 years rated their weight and/or shape as being very or extremely important.
