Mobile phones are ubiquitous in everyday life. Scientific studies on the problematic use of mobile phones have given initial indications of negative consequences, such as increased depression and anxiety rates and reduced sleep quality. The Problematic Use of Mobile Phone (PUMP) scale is a well evaluated, 20-item questionnaire, but a German version of the scale is still lacking.
An online sample (n = 723, age 27.8 ± 11.2 years, 25.2% men) completed a German translation of the PUMP scale (PUMP-D). We conducted standard item analyses and calculated internal consistency and retest reliability. An exploratory (EFA) and a confirmatory factor analysis (CFA) were conducted using a random split of the sample, and correlations with the self-estimated time of mobile phone usage and a global self-rating of patterns of problematic use were computed. Additionally, a second sample (n = 256, age 25.0 ± 8.8 years, 34.0% men) completed the paper version of the PUMP-D scale twice to determine the 14-day retest reliability.
The item-total correlations ranged from = 0.35 (p < 0.001) to = 0.75 (p < .001). The internal consistency was α = 0.90. The self-estimated time of usage correlated with the total value of the PUMP-D scale at = 0.50 (p < .001). The EFA resulted in a single factor, which explained 36% of the variance. The CFA of the showed a moderate fit. The two-week retest reliability in the second sample was = 0.87 (p < .001).
The German translation of the PUMP-D demonstrated a single factor structure, good psychometric properties and can be used in further research.
手机在日常生活中无处不在。关于手机使用问题的科学研究已初步显示出一些负面后果，如抑郁和焦虑发生率增加以及睡眠质量下降。手机使用问题（PUMP）量表是一个经过充分评估的、包含20个条目的问卷，但该量表的德文版仍然缺失。
一个在线样本（n = 723，年龄27.8 ± 11.2岁，25.2%为男性）完成了PUMP量表的德文翻译版（PUMP-D）。我们进行了标准的项目分析，并计算了内部一致性和重测信度。使用样本的随机划分进行了探索性因素分析（EFA）和验证性因素分析（CFA），并计算了与自我估计的手机使用时间以及问题使用模式的整体自我评分的相关性。此外，第二个样本（n = 256，年龄25.0 ± 8.8岁，34.0%为男性）两次完成了PUMP-D量表的纸质版，以确定14天的重测信度。
项目与总分的相关性范围为 = 0.35（p < 0.001）至 = 0.75（p <.001）。内部一致性为α = 0.90。自我估计的使用时间与PUMP-D量表的总分相关性为 = 0.50（p <.001）。探索性因素分析得出一个单一因素，该因素解释了36%的方差。验证性因素分析显示拟合度适中。第二个样本中的两周重测信度为 = 0.87（p <.001）。
PUMP-D的德文翻译版显示出单一因素结构、良好的心理测量特性，可用于进一步研究。
