CSA investigators at risk of moral injury according to new research.

Police who investigate online crimes against children are themselves at risk of moral injury and other psychological

harms, according to new research.

Researchers at the University of Portsmouth and Solent University explored moral injury amongst child exploitation

investigators and interviewed police officers from two Constabularies during a year-long study. 


The CREST (Centre for Research and Evidence on Security Threats) funded project, asked questions relating to

motivations for beginning the role, any personality changes, prior trauma, difficulties relating to their current role,

coping mechanisms, moral decision making and use of professional support.

Professor Peter Lee, Director of Security and Risk Research and Innovation at the University of Portsmouth, said:

“We found that law enforcement professionals who investigate child exploitation can be continually exposed to

traumatising visual images in their jobs for years on end. This makes them particularly vulnerable to moral injury,

PTSD, anxiety, depression and secondary trauma."

He said that ‘investigating online child sex crime is an extreme example of regularly and repeatedly witnessing acts

that transgress the moral frameworks of those involved.’

“This study is important to find out more about the causes and consequences of moral injury amongst these police

investigators to enhance support in the future.”


Researchers found that some individuals were distressed by their current role. This was a consequence of repeatedly experiencing intrusive thoughts and images, with overwhelming workloads and timeframes.

The study suggests ways to improve management of the psychological distress of viewing indecent images by enhancing current professional support. Police officers rely heavily on family and peer support to help process their distress, rather than use the current help available to them. 

Dr Mark Doyle, Solent University said: “We also aim to improve the recognition, training and professional support for those who conduct this difficult role. We have identified a number of areas for follow-on research and engagement with police online investigators to enhance existing support schemes and develop new specialised training to promote the psychological wellbeing of those on the front line.”


The evidence and insights from the research will help to enhance good mental health practice, not just for these police investigators but for other professionals whose work can be mentally traumatic.

The research team hopes to go on to establish greater understanding of the prevalence and severity of mental health difficulties, personality change, mental health stigma, behavioural and other factors that specifically influence wellbeing.
