Study Links Problematic Pornography Use to Increased Suicidal Thoughts

A recent study published in the Psychology of Addictive Behaviors has revealed a significant correlation between problematic pornography use (PPU) and suicidal thoughts.

The research aimed to investigate the relationship between PPU and suicidal ideation (SI) both cross-sectionally and longitudinally. Two independent samples were used: one consisting of undergraduate students and another of a nationally representative sample of U.S. adults. The researchers sought to understand if PPU could be linked to past-month suicidal thoughts and the perceived likelihood of future suicidal behaviours while controlling for factors such as the frequency of pornography use, moral disapproval, moral incongruence, and religiousness.

The study’s findings indicate that PPU is associated with higher levels of self-perceived likelihood of suicidal behaviours but not necessarily with past-month suicidal thoughts in cross-sectional analyses. Longitudinally, PPU was linked to higher initial levels of both past-month suicidal thoughts and self-perceived likelihood of suicidal behaviours, though it did not predict changes over time. These associations persisted even when accounting for the frequency of pornography use, which was statistically unrelated to suicidal outcomes.

The research utilised path analysis and latent growth curve modelling to assess the data. For the undergraduate sample, PPU was significantly related to the self-perceived likelihood of suicidal behaviours, whereas the frequency of pornography use and moral disapproval were not. Interestingly, higher moral disapproval of pornography use was correlated with lower past-month suicidal ideation among college students.

In the nationally representative sample, the findings were consistent. PPU predicted greater initial levels of suicidal thoughts and perceived likelihood of suicidal behaviours. But over the two-year follow-up period, these levels did not significantly change, indicating that while PPU may establish a baseline risk, it does not necessarily exacerbate suicidal thoughts over time.

The study highlights the importance of considering PPU in clinical settings, particularly for individuals who report feelings of addiction to pornography. Clinicians are advised to assess for suicidal ideation in patients presenting with PPU or compulsive sexual behaviours (CSBs). The findings underscore the need for comprehensive approaches that address the emotional and cognitive aspects of PPU, including distorted cognitions and affect regulation.

For researchers, this study provides a foundation for further exploration into the psychiatric comorbidities associated with PPU and CSBD. The authors call for more rigorous research and public funding to better understand and address these complex behaviours and their psychological impacts.

The inclusion of compulsive sexual behaviour disorder (CSBD) in the World Health Organization’s International Classification of Diseases-11 (ICD-11) reflects a growing recognition of the clinical significance of out-of-control sexual behaviours. This study contributes to the evidence base, suggesting that PPU is not only a prevalent issue but also one that can significantly impact mental health, particularly in terms of suicidal thoughts.

While the study provides valuable insights, it also acknowledges certain limitations. The cross-sectional and longitudinal designs do not allow for causal inferences, and the reliance on self-reported data may introduce bias. Future research should aim to include more diverse samples and utilise methods such as ecological momentary assessment to capture the variability in suicidal thoughts and PPU.

The authors also suggest that future studies should explore the mechanisms through which PPU influences suicidal ideation, considering factors like emotion regulation, social isolation, and moral incongruence. By understanding these underlying processes, more effective interventions can be developed to mitigate the risks associated with PPU.
