Voyeuristic Disorder: Diagnosis, Harm and Treatment

Looking is part of human sexuality. Many people feel excited when they see someone they are attracted to, and many enjoy watching their partner with that partner's knowledge and enjoyment. None of this is a problem. The line lies in the words "unaware and not consenting". When arousal is tied to secretly watching or filming people who don't know, that is the point where a preference becomes a violation.

This article is part of the Paraphilic disorders series, written for understanding and prevention.

What is voyeuristic disorder?

According to DSM-5-TR (2022), voyeuristic disorder is diagnosed when:

1. There is recurrent and intense sexual arousal from observing an unsuspecting person who is naked, undressing or engaged in sexual activity, shown through fantasies, urges or behaviors, for at least 6 months
2. The person has acted on these urges with a non-consenting person, or the urges cause clinically significant distress or impairment in functioning
3. The person is at least 18 years old, because sexual curiosity in adolescence is a normal part of development that needs to be distinguished (though this does not mean secret filming by teenagers is acceptable)

The doctor may add the specifiers "in a controlled environment" or "in full remission" when there has been no acting on urges and no distress for at least 5 years while living normally. ICD-11 classifies it under code 6D31 Voyeuristic disorder, with the emphasis on acts towards non-consenting people.

Preference vs a condition that should be treated

A survey in Canada (Joyal & Carpentier, 2017) found that almost half of adults had at some point "wanted" to secretly watch someone. So the feeling itself is common. What separates most people from a condition that needs treatment is not acting on it, and choosing to meet their needs in ways that involve consent.

The smartphone era: secret filming causes lasting harm

Today voyeurism doesn't stop at looking. It includes upskirt filming, tiny hidden cameras and sharing images in online groups. Many victims feel humiliated and fearful, can't sleep and lose their sense of safety in private spaces. Once images are leaked, the effects can follow them for years.

In Thailand, these acts may break several laws: the law on computer-related offences when images are distributed, and the Criminal Code amendment (No. 30) B.E. 2568 (2025), in force from 30 December 2025, which created an offence of sexual harassment covering words, gestures, staring and acts through electronic means, with heavier penalties when committed in public, online or against children under 15. Sexual images of children count as child sexual abuse material, and possessing or sharing them is a serious crime.

Causes and co-occurring factors

There is no single explanation. Factors often found together include learning to associate excitement with risk from adolescence, social anxiety or difficulty forming close relationships, compulsive use of sexual media, drinking or substance use, and depression. Some people also have other conditions in the same group, such as exhibitionistic disorder or frotteuristic disorder.

Assessment and treatment

Assessment is confidential and covers the pattern of behavior, frequency, triggers, risk to others, co-occurring mental health conditions and motivation to change.

Psychological therapy is at the core:

• CBT helps identify risky situations and self-justifying thoughts, such as "they don't know, so there's no harm", and practise alternatives when urges arise
• A relapse prevention plan, such as avoiding risky places or times, carrying recording devices less, limiting access to triggering media and having a trusted person for support
• Relationship and emotion-regulation skills, so that sexual needs can be met in consensual relationships
• Treating co-occurring conditions, such as depression, anxiety and alcohol use

Medication is considered only for people with severe urges or high risk, following the WFSBP (2020) guidelines, and must be under a psychiatrist's care. Our clinic provides screening, counseling and appropriate referral.

If you're worried about this

The fact that you've read this far means you want to change, which is a very good starting point.

• Stop and step away from risky situations right away. Delete the devices or apps used for secret filming.
• Consult a doctor or clinical sexologist in confidence; see When to see a clinical sexologist
• If you feel severe distress or have thoughts of harming yourself, call 1323, Thailand's mental-health hotline (Thai language; ask for English support)
• If you have been secretly filmed, keep the evidence, report it to the police on 191 and get help from the Social Assistance Center on 1300
