BACKGROUND The Problematic Pornography Use Scale (PPUS) was originally designed to help predicting pornography consumption. Despite the frequency with which this scale is used in the scientific literature, there is still relatively little evidence regarding the predictive validity of this important instrument. This current research introduces a construct capable of improving the ability of the scale to predict pornography consumption (meta-cognitive certainty). METHOD Over two studies, participants completed the PPUS and the meta-cognitive certainty in their responses to the scale was measured (Study 1) or manipulated (Study 2). Self-reported porn consumption was the criterion measure in both studies, with an additional actual overt behavior relevant to consumption of porn included in Study 2. RESULTS As expected, the PPUS significantly predicted porn consumption, confirming the predictive validity of the scale. More importantly, meta-cognitive certainty was capable of moderating the extent to which scores on the PPUS could predict porn consumption, with greater consistency between the PPUS and reported behavior from those with high (vs. low) meta-cognitive certainty. CONCLUSIONS These data suggest that considering meta-cognitive certainty may be useful for predicting when the link between the PPUS and porn consumption is stronger.

元认知确定性对色情消费的作用。

背景 有问题的色情使用量表 (PPUS) 最初旨在帮助预测色情消费。尽管该量表在科学文献中使用频率很高，但关于这一重要工具的预测有效性的证据仍然相对较少。当前的这项研究引入了一种能够提高量表预测色情消费（元认知确定性）能力的结构。方法 在两项研究中，参与者完成了 PPUS 并测量（研究 1）或操纵（研究 2）他们对量表反应的元认知确定性。自我报告的色情消费是两项研究中的标准衡量标准，研究 2 中包含与色情消费相关的额外实际公开行为。 结果正如预期的那样，PPUS 显着预测了色情消费，证实了该量表的预测有效性。更重要的是，元认知确定性能够调节 PPUS 分数可以预测色情消费的程度，PPUS 与具有高（与低）元认知确定性的人报告的行为之间具有更大的一致性。结论 这些数据表明，考虑元认知确定性可能有助于预测 PPUS 与色情消费之间的联系何时更强。
