Pornography Use and Mental Health Problems in the Chinese Population: Examining the Pornography Problems Due to Moral Incongruence Model

Pornography has become increasingly prevalent worldwide with the development of the Internet, and considerable research on the effects of pornography use has emerged. Based on existing research and the Pornography Problems Due to Moral Incongruence (PPMI) model, we examined problematic pornography use (PPU) as a mediator and moral disapproval of pornography use as a moderator in the links between pornography use frequency and mental health problems in a Chinese sample (N = 833). Our results support the completely mediated effect of PPU (ab = 0.16) and the moderated effect of moral disapproval of pornography use on the association between pornography use frequency and PPU. Pornography use frequency was strongly associated with PPU when participants experienced high moral incongruence (MI), and the indirect effect of PPU was weaker (ab = 0.13) at the lower level of moderator (-1 SD), and stronger (ab = 0.23) at the higher level of moderator (+1 SD). However, the direct effect of MI on mental health problems was not supported. This study advances our understanding of the internal mechanism between pornography use and mental health and extends the PPMI model to the Chinese cultural context (characterized as low religiosity and sexually conservative). The findings confirm the cross-cultural consistency of the PPMI model in China and highlight another important source of MI besides religiosity: cultural characteristics.

Treatment Approaches for Problematic Pornography Use: A Systematic Review

Problematic pornography use (PPU) is an emerging condition associated with several negative psychological and sexual outcomes. This study aimed to systematically review treatment approaches for PPU. Potentially eligible studies were searched for in PubMed/MEDLINE, Embase, PsycINFO, and Web of Science up to April 1, 2023. The quality of the evidence was assessed with the use of the Joanna Briggs Institute's checklists, the Cochrane risk-of-bias tools, and the GRADE approach. A total of 8936 references were retrieved, and 28 studies were included in the systematic review (n = 500 participants). Included studies were case reports (k = 16), case series (k = 1), quasi-experimental investigations (k = 7), and randomized clinical trials (k = 4). The majority of included studies presented overall low quality and significant risk of bias, with all interventions receiving a low or very low rating according to the GRADE approach. Most studies investigated psychological interventions, with the predominance of second and third wave cognitive behavioral therapy interventions. Pharmacological treatments included opioid antagonists (naltrexone in most cases) and antidepressants, while one study investigated a protocol that included rTMS. Several investigations described the combination of psychological and pharmacological approaches. Most studies did not report on side effects, with online and self-help interventions presenting significant issues in terms of treatment adherence. Even though there are promising options that may have efficacy for the treatment of patients with PPU, the literature in the topic still presents significant limitations that compromise the reaching of more definitive conclusions.

Withdrawal-like Symptoms in Problematic Pornography Use: A Scoping Review

OBJECTIVES

There is still debate whether problematic pornography use (PPU) can be understood as an addictive disorder, and little is known about withdrawal-like symptoms in these patients. Therefore, our aim was to summarize the existing scientific literature about this topic in the format of a scoping review.

METHODS

Potentially eligible references were retrieved from 6 databases (MEDLINE/PubMed, Web of Science, Embase, PsycINFO, LILACS, and SciELO) up to February 7, 2023. Studies were included if they reported original data about withdrawal-like symptoms in individuals with PPU. Studies investigating child pornography use, or in which it was not possible to extract data of interest were excluded. Data extracted from included studies and their quality assessment were described narratively.

RESULTS

A total of 937 references were retrieved, and 14 studies were included (n = 31,009 participants). According to our results, cravings were intense in most cases and frequent reasons for relapse. The proportion of participants experiencing other withdrawal-like symptoms (mental, sexual, and physical symptoms) reached up to 72.2% in the cross-sectional studies with this information available. Severity of withdrawal symptoms was associated with severity of PPU and frequency of pornography use. In some studies, measures of withdrawal symptoms were considered central symptoms of PPU and were significantly higher in individuals considering treatment. Masturbation was reported to alleviate withdrawal-like symptoms in some cases.

CONCLUSIONS

There is preliminary evidence for the existence of withdrawal-like symptoms in PPU. Future studies should investigate onset, characteristics, duration, and proportion of withdrawal-like symptoms in PPU with robust methodology, also investigating potential confounding variables.
