While some individuals engage in recreational pornography use (PU), others may develop an uncontrolled pattern of use termed problematic pornography use (PPU). PPU is characterized by persistent, excessive, or compulsive engagement with pornographic content, despite distress and adverse consequences. Impulsivity has been identified as a factor associated with PU and PPU. The present meta-analysis aims to sum up the existing research on the relationship between impulsivity and PU/PPU and investigate whether age and gender could moderate this relationship. A keyword-based systematic literature search was performed to identify articles that assessed PU/PPU and impulsivity. Extracted correlations were converted into Fisher’s Z. Meta-regression analyses were also performed. Publication bias was assessed by Egger’s regression intercept. Outcomes included general impulsivity and its dimensions (ie, negative and positive urgency, lack of premeditation and perseverance), sensation seeking, PU, and PPU. Meta-analytic results of the random effects model showed a significant positive correlation between impulsivity as total score and PU (n = 1504, k = 4, Fisher’s Z = 0.21, P < .001) and PPU (n = 20174, k = 13, Fisher’s Z = 0.17, P < .001). Significant and positive associations were also found between sensation seeking and PU (n = 11707, k = 11, Fisher’s Z = 0.14, P < .001) and PPU (n = 20152, k = 9, Fisher’s Z = 0.06, P < .001). Concerning the relationship between PPU and different dimensions of impulsivity, almost all the associations were significant and positive. The dimension of positive urgency and attentional and nonplanning impulsivity showed the strongest association. Age (β = –0.50, Q = 101.26, df = 11, P < .001) and gender (female = 1; β = –0.46, Q = 102.54, df = 12, P < .001) moderated the association between general impulsivity and PPU. No risk of publication bias emerged. Prevention programs of PPU should focus on impulsivity and certain key dimensions (eg, positive urgency, attentional and nonplanning impulsivity) and be tailored to individual impulsivity profiles, considering age and gender differences. The primary strength of this meta-analysis is that it considers various conceptualizations of impulsivity. However, the results are to be interpreted with caution since >30% of relevant studies had to be excluded because information could not be gathered from the study authors. These results suggest that general impulsivity is linked to PU and PPU and that specific dimensions of impulsivity (ie, attentional impulsivity, nonplanning impulsivity, and positive urgency) can serve as risk factors for PPU.

In recent years, a growing number of attachment-based studies have contributed to the understanding of both substance and behavioral addictions. Although gambling is a form of addictive behavior widespread all over the world, both among young people and adults, the evidence on the association between attachment-related phenomena and gambling has not yet been systematized in literature. The aim of the present study, therefore, is to provide a systematic literature review aimed at summarizing the empirical evidence on this topic. Following the updated 2020 PRISMA guidelines, a systematic search in four electronic scientific databases (Scopus, PubMed, PsycInfo and Web of Science) was conducted. After removing duplicates, 146 records were double-screened, with 12 articles meeting the inclusion criteria. Additionally, by means of a backward search a further article was selected. Altogether, 13 articles were selected for the present systematic review. With few exceptions, the results underline the significant role played by attachment-related phenomena in gambling behaviors, highlighting that specific attachment contexts have a different influence on gambling, also depending on whether gamblers are youths or adults. In particular, while secure attachment has proven to be a protective factor for the onset of gambling behavior, insecure attachment has emerged to be a vulnerability factor in two ways. On the one hand, it directly favors gambling behaviors; on the other, it affects coping strategies and the individual’s ability to identify and regulate emotions, which in turn predict gambling. Limitations, strengths, and implications of the present systematic review are discussed.

The aim of this study was to analyze the direct and indirect relationships between the two phenotypes of narcissism, vulnerable and grandiose, and the tendency to perpetrate psychological abuse, exploring the mediating role of romantic jealousy. Our sample included 473 participants (213 males), aged 18–30 years (M = 22.74; SD = 2.81), involved in a stable romantic relationship. A structural equation modeling was conducted to test our model and a multigroup analysis was performed to test gender differences. Results show that the two forms of narcissism are both linked to psychological perpetrated abuse, but in different ways. Vulnerable narcissism was linked to psychological abuse only indirectly, through the role of romantic jealousy. On the contrary, grandiose narcissism was positively and directly associated with psychological abuse within the romantic relationship. Moreover, the model was invariant across genders. Limitations, strengths, and theoretical and clinical implications are discussed.
