Home › Guides › Online games and play-time evidence: what a psychiatric expert can and cannot infer
Records of online gaming are increasingly part of the material that reaches a psychiatric expert. A solicitor may send screenshots of a console, a family member may describe the hours spent at a keyboard, or a platform may have produced an account history. Each can seem like a precise measure of behaviour. In practice, play-time information is one piece of evidence among many, and it has real limits.
This article explains, in general terms, how an expert approaches play-time evidence in a medico-legal report. It does not describe any particular case, and it is not legal advice. For the general framework of these reports, see our guide to what a psychiatric medico-legal report is.
Where play-time information comes from
Play-time evidence usually arrives in one of four forms. Each has different strengths and weaknesses.
- Self-report. The person describes how long they play, when, and with what effect. This is valuable for understanding their own experience, but memory for hours is often approximate, particularly for games played over long periods.
- Family or third-party accounts. Partners, parents, friends or colleagues may describe what they have seen. These accounts can be useful for context, but they reflect the observer’s vantage point and may be affected by their own concerns or the circumstances of the case.
- Screenshots and device records. A phone or console may show usage figures for a given period. These can be helpful, but the figures depend on how the device counts time, whether it was shared, and whether it was switched on in the background.
- Platform account histories. Some games provide records of sessions or purchases. These are often the most detailed, but they may cover only part of the period in question, or may not separate solo play from shared sessions.
The expert will want to know where each piece of information came from, when it was produced, and whether anyone has checked it against another source.
Why hours alone do not establish a diagnosis
A large number of hours at a game does not, by itself, meet clinical criteria for any disorder. Play can be a normal leisure activity, a social activity, a work activity for some people, or a way of relaxing after a hard day. The question for the expert is not how long someone played, but whether the pattern of play caused significant harm and loss of control.
The international classification ICD-11 recognises gaming disorder as a pattern of persistent or recurrent gaming behaviour, with impaired control, increasing priority given to gaming over other interests, and continuation despite negative consequences. The diagnosis also requires significant impairment in personal, family, social, educational, occupational or other important areas of functioning. The expert will look for evidence of each element rather than treating play time as a proxy for all of them.
What the expert will look for
When play-time evidence is in the bundle, an expert usually works through a set of questions:
- Period. Which dates does the evidence cover, and do they match the period at issue in the instruction?
- Completeness. Are there gaps in the records, and is there a reason the device or account might not show all the play?
- Pattern. Was the play steady, increasing or variable? Did it change around particular events?
- Control. Did the person try to cut down, and what happened when they did?
- Consequences. What was affected at work, at school, at home, in relationships and in health?
- Alternatives. Could the pattern be explained by something else, such as low mood, anxiety, sleep disturbance or a response to a physical injury?
The expert will say which of these questions the evidence can answer and which it cannot. That honesty is part of a sound report.
Reliability and interpretation
Play-time figures are easy to misread. A figure that looks high may include time the device was left on while the person was elsewhere. A figure that looks low may not include play on a second device or a different account. Shared accounts, household devices and game features that run while the console is idle can all distort the picture.
The expert may therefore ask for the original records rather than a summary, and may ask the instructing solicitor to clarify how a figure was calculated. Where the evidence is incomplete, the report should say so, and should explain what can and cannot be concluded from it.
Wording in the report
Careful wording matters. An expert will usually say that a person “reported” a pattern of play, or that the records “show” a total for a given period, rather than stating as fact things the expert cannot verify. Where the evidence supports a view, the report may say that a pattern is consistent with a particular diagnosis, while explaining the reasons and the limits of that view.
A report should not use play-time figures to imply a diagnosis that the wider assessment does not support. It should also avoid moral language about gaming in general, because the question is clinical and legal rather than a judgement about leisure.
What a solicitor can usefully do
Instructing solicitors can help by sending the original records, explaining where each piece of evidence came from, and identifying the period that matters for the case. A short chronology, prepared from the records, can be more useful than a bundle of screenshots with no explanation.
It also helps to flag any changes in circumstances during the period, such as a change of job, a move, an injury or a bereavement, because these may affect how the play-time information should be read.
Key points
- Play-time evidence can come from self-report, third-party accounts, device records or platform histories, and each has limits.
- Hours of play do not by themselves establish a disorder under ICD-11.
- The expert considers period, completeness, pattern, control, consequences and alternative explanations.
- Shared devices and background activity can distort usage figures, so the original records matter.
- Careful wording, such as “reported” or “consistent with”, keeps the report within what the evidence supports.
- A clear chronology from the instructing side helps the expert focus on what matters.
