Main question
How much of self-perceived "porn addiction" is explained by moral incongruence rather than use?
Summary
Grubbs, Perry, Wilt, and Reid (2019) integrated existing research and conducted a systematic review and meta-analysis of the relationship between moral incongruence and self-reported problems with pornography. Moral incongruence refers to the distress people feel when their behaviour conflicts with their moral or religious values.
Main finding
The authors found that moral incongruence is a major — and frequently the strongest — predictor of whether a person labels themselves as “addicted” to pornography. This label is often driven more by the moral conflict than by how much pornography the person actually views.
Why it matters
This work is central to understanding how PPU is defined and why the behavioural addiction debate is not only about brain science but also about values and self-perception. It does not, on its own, settle whether heavy use is harmful.
Findings
- Moral incongruence — distress arising from a mismatch between a person's moral or religious beliefs and their behaviour — is a strong and often the strongest predictor of self-perceived 'pornography addiction'.
- Self-perceived addiction is more closely tied to moral conflict than to the amount or frequency of pornography use itself.
- Feelings of being 'addicted' are strongly associated with psychological and spiritual distress, independent of actual usage levels.
Limitations
- Relies predominantly on self-report measures of both use and perceived addiction.
- Does not resolve whether heavy pornography use has independent harms separate from moral distress.

Clinical relevance
Suggests clinicians should assess moral distress separately from behaviour.
Relevance to problematic pornography use
Central to understanding why people label their use as problematic.
