To address current gaps around screening for problematic pornography use (PPU), we initially developed and tested a six-item Brief Pornography Screen (BPS) that asked about PPU in the past six months.
We recruited five independent samples from the U.S. and Poland to evaluate the psychometric properties of the BPS. In Study 1, we evaluated the factor structure, reliability, and elements of validity using a sample of 224 U.S. veterans. One item from the BPS was dropped in Study 1 due to low item endorsement. In Studies 2 and 3, we further investigated the five-item the factor structure of the BPS and evaluated its reliability and validity in two national U.S. representative samples (N = 1,466, N = 1,063, respectively). In Study 4, we confirmed the factor structure and evaluated its validity and reliability using a sample of 703 Polish adults. In Study 5, we calculated the suggested cut-off score for the screen using a sample of 105 male patients seeking treatment for compulsive sexual behavior disorder (CSBD).
Findings from a principal components analysis and confirmatory factor analysis supported a one-factor solution which yielded high internal consistency (α = 0.89-0.90), and analyses further supported elements of construct, convergent, criterion, and discriminant validity of the newly developed screen. Results from a Receiver Operating Characteristic (ROC) curve suggested a cut-off score of four or higher for detecting possible PPU.
The BPS appears to be psychometrically sound, short, and easy to use in various settings with high potential for use in populations across international jurisdictions.
为了弥补目前在问题性色情使用（PPU）筛查方面的空白，我们最初开发并测试了一个六条目简短色情使用筛查（BPS），用于询问过去六个月内的 PPU 情况。
我们从美国和波兰招募了五个独立的样本，以评估 BPS 的心理测量学特性。在研究 1 中，我们使用 224 名美国退伍军人的样本评估了 BPS 的因子结构、信度和效度要素。由于项目低认可度，BPS 中有一个项目在研究 1 中被删除。在研究 2 和 3 中，我们进一步研究了 BPS 的五条目因子结构，并在两个美国全国代表性样本（分别为 N=1466，N=1063）中评估了其信度和效度。在研究 4 中，我们使用 703 名波兰成年人的样本证实了因子结构，并评估了其效度和信度。在研究 5 中，我们使用 105 名寻求治疗强迫性性行为障碍（CSBD）的男性患者的样本计算了该筛查的建议截断分数。
主成分分析和验证性因子分析的结果支持了一个单因素解决方案，该方案产生了较高的内部一致性（α=0.89-0.90），分析进一步支持了该新开发的筛查的结构、收敛、标准和判别效度要素。接收器操作特征（ROC）曲线的结果表明，四或更高的截断分数可用于检测可能的 PPU。
BPS 似乎具有良好的心理测量学特性，简短易用，在各种环境下都具有较高的应用潜力，可用于国际司法管辖区的人群。
