Main question

Who self-identifies as "addicted" to pornography in the general population, and why?

Related claims

Summary

Using a nationally representative sample of US adults, Grubbs, Kraus, and Perry (2019) examined who reports feeling “addicted” to pornography and what predicts that feeling.

Key findings

Religiousness and moral disapproval were stronger predictors of self-reported addiction than the amount of pornography a person actually used. This supports the moral incongruence account: people are more likely to feel “addicted” when their use conflicts with their values.

Why it matters

This study is frequently cited in the behavioural addiction debate because it suggests that self-identification as “addicted” is not a simple reflection of heavy use. It informs how we read community claims about PPU.

Findings

What this study can support

Indicates self-reported addiction may reflect moral conflict rather than heavy use.

What it cannot establish

Causal conclusions beyond the study design; generalizations to populations, behaviors, or contexts outside the sample; and any claim not directly measured.

Limitations

Clinical relevance

Indicates self-reported addiction may reflect moral conflict rather than heavy use.

Relevance to problematic pornography use

Shows self-perceived problems track moral incongruence more than frequency.
