Whilst still in politics Whitely wrote
Speed Up and Sit Still - The Controversies of ADHD Diagnosis and Treatment (UWA Publishing 2010). Since retiring from politics he completed a PhD (thesis title
ADHD Policy, Practice and Regulatory Capture in Australia 1992–2012). Subsequently, he has researched Australian mental health policy and practice and pharmaceutical and medical device regulation. His research has primarily focused on the drivers and outcomes of prescription mental health medication use by children, adolescents and young adults for ADHD and depression.
ADHD research Whitely led two research projects examining the effect of relative-age within a school classroom on the probability of school-children being medicated for
ADHD. The first,
Influence of birth month of Western Australian children on the probability of being treated for ADHD, was published in the Medical Journal of Australia in 2017. It found that among West Australian school children aged 6–10 the youngest in class (born in June) were approximately twice as likely to take ADHD medication as their oldest classmates (born the previous July). The second,
Attention deficit hyperactivity disorder late birthdate effect common in both high and low prescribing international jurisdictions: a systematic review, published in 2019 examined 22 studies in 13 countries covering 15.4 million children. It found that is the global norm for the youngest students within a school year grade to be diagnosed with and medicated for ADHD than there older classmates. Whitely also co-authored a paper published in 2020,
Look west for Australian evidence of the relationship between amphetamine‐type stimulant prescribing and meth/amphetamine use. It reviewed Western Australian (WA) evidence of the relationship between prescribing amphetamine type stimulants for ADHD and the illicit use of amphetamines. It found that the non-medical use of prescription ATS by WA secondary school students is the major component of their illicit amphetamine use. It also reported that since at least 2002 WA adults have been prescribed ATS at a much higher rate than other Australian adults and WA adult illicit amphetamine use rates have consistently been among the highest in Australia.
Research examining antidepressant use and suicide by young Australians Whitely led research published in 2020,
Antidepressant Prescribing and Suicide/Self-Harm by Young Australians: Regulatory Warnings, Contradictory Advice, and Long-Term Trends. It examined the Australian response to the US
Food and Drug Administration's (FDA) 2004 black box warnings that antidepressant use was associated with an elevated risk of suicidal thinking and behaviours in people aged under 25.This research found that in the four years following the 2004 FDA warning there was a 31% decrease in antidepressant prescribing and a small fall in the rate of suicide by young Australians. However, from 2009 to 2018 the rates of antidepressant use and suicide by young Australians increased consistently. In 2009 there were 275 suicides by Australians aged under 25 years, in 2018 this number rose to 458. Whitely, and his co-authors Prof Jon Juriedini and Dr Melissa Raven, concluded “correlation does not prove causation. However, given that the FDA warned that antidepressants were associated with an approximately doubled risk of suicidality relative to placebo, we are not surprised that rising dispensing rates have been accompanied by increasing youth suicide rates”. == Parliamentary career ==
