BACKGROUND
Short versions of problematic internet use (PIU) questionnaires may provide a convenient and effective way of assessing internet-related problems in various contexts, ranging from research to clinical practice. The aim of this study was to investigate whether single yes/no question (Q-single) regarding "functional impairment due to PIU" could serve as a screening tool to indicate the potential absence of PIU, given the lack of functional impairment.
METHODS
Data from two online studies (N = 524 and N = 272) assessing internet-related behaviors among students were used for the analyses. Participants completed questionnaires (the nine-item Problematic Internet Use Questionnaire [PIUQ-9], the Compulsive Internet Use Scale [CIUS], the nine-item Patient Health Questionnaire, depression module [PHQ-9], the seven-item Generalized Anxiety Disorder scale [GAD-7]), questions about their internet use time, besides answering the Q-Single question. Block-wise multiple linear regression analyses were used to determine the predictive effect of the Q-Single on PIU (as measured with the PIUQ-9 and the CIUS) and its association with depression and anxiety symptom scores (as measured with the PHQ-9 and the GAD-7).
RESULTS
The Q-Single demonstrated a high negative predictive value in screening the absence of PIU, however positive predictive value was low to moderate. Q-Single proved to be a good predictor of PIU (β = 0.484, p < 0.001 [PIUQ-9] and β = 0.481, p < 0.001 [CIUS]) when controlling for age, gender, and internet use time. Adjusting for the same controlling variables, the Q-Single had a moderate association with depression symptoms (β = 0.385, p < 0.001 [PHQ-9]) and anxiety symptoms (β = 0.252, p < 0.001) [GAD-7]) supporting the validity of the single-question instrument.
CONCLUSIONS
The finding that a single question could predict absence of PIU in students, implies that functional impairment is an important indicator of PIU.
背景
问题性互联网使用（PIU）问卷的简短版本可能提供一种便捷有效的方法，用于在从研究到临床实践的各种情境中评估与互联网相关的问题。鉴于缺乏功能损害，本研究的目的是调查关于“PIU导致的功能损害”的单一是/否问题（Q-单一）是否可以作为一种筛查工具，以表明可能不存在PIU。
方法
来自两项评估学生互联网相关行为的在线研究（N = 524和N = 272）的数据用于分析。除了回答Q-单一问题外，参与者还完成了问卷（九项问题性互联网使用问卷[PIUQ-9]、强迫性互联网使用量表[CIUS]、九项患者健康问卷抑郁模块[PHQ-9]、七项广泛性焦虑障碍量表[GAD-7]），以及关于他们互联网使用时间的问题。采用逐步多元线性回归分析来确定Q-单一问题对PIU（用PIUQ-9和CIUS测量）的预测作用及其与抑郁和焦虑症状评分（用PHQ-9和GAD-7测量）的关联。
结果
Q-单一问题在筛查不存在PIU方面显示出较高的阴性预测值，然而阳性预测值较低至中等。在控制年龄、性别和互联网使用时间后，Q-单一问题被证明是PIU的良好预测指标（β = 0.484，p < 0.001 [PIUQ-9]，β = 0.481，p < 0.001 [CIUS]）。在调整相同的控制变量后，Q-单一问题与抑郁症状（β = 0.385，p < 0.001 [PHQ-9]）和焦虑症状（β = 0.252，p < ......
结论
单一问题可以预测学生中不存在PIU这一发现意味着功能损害是PIU的一个重要指标。 （注：原文中“p < 0.001 [GAD-7])”后面的内容缺失，翻译时保留了原文格式）
