Since the diffusion of recent models of mobile phones, anyone with an internet connection can communicate continuously and search for information. This raises some questions about the possible consequences of problematic mobile phone use (PMPU) in a complex life phase such as adolescence. Therefore, we performed a psychometric analysis of the brief version of the Test of Mobile Phone Dependence (TMD) in Italy. The sample comprised 575 Italian adolescents aged 11 to 18 years. Data were collected using the TMD-brief, the Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance Short Form. Regarding test dimensionality, the best-fit measurement model included four factors: "Abstinence"; "Abuse and interference with other activities"; "Tolerance"; and "Lack of control" (Satorra-Bentler χ (48) = 185.96, < 0.01; robust root mean square error of approximation (RMSEA) = 0.079 (90% confidence interval (CI): 0.067; 0.091); robust TLI = 0.904; robust comparative fit index (CFI) = 0.930). The Italian version of the TMD-brief was found to have good reliability and psychometric properties, and a four-factorial structure. PMPU predicted significant sleep disturbances and this relationship was moderated by clinical personality traits. Findings from this study support the use of the Italian version of the TMD-brief as a screening tool to investigate PMPU in Italian adolescents.
自新型移动电话普及以来，任何具备互联网连接的人均可实现持续通信和信息搜索。这使得人们开始关注在青少年这一复杂人生阶段，过度使用移动电话（PMPU）可能带来的后果。因此，我们在意大利对简短版手机成瘾测试（TMD）进行了心理测量学分析。该样本包括 575 名 11 至 18 岁的意大利青少年。使用简短版 TMD、DSM-5 人格量表和 PROMIS 睡眠障碍短式量表收集数据。关于测试维度，最佳拟合测量模型包括四个因素：“禁欲”；“滥用和干扰其他活动”；“耐受”和“缺乏控制”（Satorra-Bentler χ(48)=185.96，<0.01；稳健根均方误差近似值（RMSEA）=0.079（90%置信区间（CI）：0.067；0.091）；稳健 TLI=0.904；稳健比较拟合指数（CFI）=0.930）。简短版 TMD 意大利语版本具有良好的信度和心理测量学特性，以及四因素结构。PMPU 可预测显著的睡眠障碍，而这种关系受临床人格特质的调节。本研究结果支持使用简短版 TMD 意大利语版本作为筛查工具，以调查意大利青少年的 PMPU。
