Summary

Grubbs, J. B., & Gola, M. (2019, The Journal of Sexual Medicine). Mere pornography use showed no consistent association with erectile functioning trajectories across samples.

Findings

What this study can support

Three samples including longitudinal latent growth modeling; found no relationship between mere use and ED trajectories, but consistent links between self-perceived problematic use and self-reported ED.

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

Three samples including longitudinal latent growth modeling; found no relationship between mere use and ED trajectories, but consistent links between self-perceived problematic use and self-reported ED.

Relevance to problematic pornography use

The most cited evidence on the PIED question: problems track perceived problems, not use amount.
