背景:虽然有些人从事娱乐色情使用(PU),其他人可能会发展出不受控制的使用模式,称为有问题的色情使用(PPU)。PPU的特点是持久性,过度,或者强迫性地接触色情内容,尽管痛苦和不良后果。冲动性已被确定为与PU和PPU相关的因素。
目的:本荟萃分析旨在总结现有关于冲动性与PU/PPU之间关系的研究,并探讨年龄和性别是否可以调节这种关系。
方法:进行了基于关键字的系统文献检索,以确定评估PU/PPU和冲动性的文章。将提取的相关性转换为FisherZ。还进行了Meta回归分析。通过Egger回归截距评估发表偏倚。
结果:结果包括一般的冲动性及其维度(即,消极和积极的紧迫性,缺乏预谋和毅力),寻求感觉,PU,和PPU。
结果:随机效应模型的Meta分析结果显示,冲动性总分与PU(n=1504,k=4,FisherZ=0.21,P<.001)和PPU(n=20174,k=13,FisherZ=0.17,P<.001)之间存在显著正相关。感觉寻求与PU(n=11707,k=11,Fisher'sZ=0.14,P<.001)和PPU(n=20152,k=9,Fisher'sZ=0.06,P<.001)之间也存在显着和正相关。关于PPU与冲动的不同维度之间的关系,几乎所有的关联都是显著的和积极的。积极的紧迫性与注意力和非计划冲动性的维度显示出最强的关联。年龄(β=-0.50,Q=101.26,df=11,P<.001)和性别(女性=1;β=-0.46,Q=102.54,df=12,P<.001)缓和了一般冲动与PPU之间的关联。没有出现发表偏倚的风险。
结论:PPU的预防计划应侧重于冲动性和某些关键方面(例如,积极的紧迫性,注意和非计划冲动),并根据个人冲动概况量身定制,考虑到年龄和性别差异。
■这种荟萃分析的主要优势在于,它考虑了冲动性的各种概念化。然而,本研究结果应谨慎解释,因为>30%的相关研究必须被排除,因为无法从研究作者那里收集信息.
结论:这些结果表明,一般冲动性与PU和PPU有关,并且冲动性的特定维度(即,注意力冲动,非计划性冲动,和积极的紧迫性)可以作为PPU的风险因素。
BACKGROUND: 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.
OBJECTIVE: 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.
METHODS: 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.
RESULTS: Outcomes included general impulsivity and its dimensions (ie, negative and positive urgency, lack of premeditation and perseverance), sensation seeking, PU, and PPU.
RESULTS: 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.
CONCLUSIONS: 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.
UNASSIGNED: 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.
CONCLUSIONS: 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.
