The current study aims to measure the validity, reliability, and psychometric properties of the Persian translation of the Video Gaming Addiction Test (VAT).
A total of 280 young men (14-20 years old) (Mean±SD age: 17.22±1.8 years), including excessive gamers and normal subjects, entered the study. They answered VAT, Visual Analog Scale (VAS), and Conner-Davidson Resilience Scale (CD-RISC). The VAT was translated and then back-translated. For testing reliability, we used the Cronbach alpha, split-half method, and Guttman method. Also, convergent and discriminant validity were tested to examine the construct validity of the translated version of VAT.
The Cronbach alpha for the total scale was 0.81. Also, after splitting questions in half, the Cronbach alpha values for these halves were 0.71 and 0.69. Six Guttman lambdas were calculated with 0.75 minimum and 0.82 maximum, all showing good reliability of the test. Convergent validity was tested by testing the correlation between VAT and VAS. The Pearson correlation was fond 0.73, showing a strong relationship between the two factors (P<0.001). For testing discriminant validity, the association of VAT with CD-RISC was tested, showing no correlation between these scales (r=-0.157; P=0.09).
The Persian translation of the VAT is valid and reliable, and it is appropriate for research and clinical use with acceptable properties, similar to the original version.
本研究旨在评估《视频游戏成瘾测试》（VAT）波斯语翻译版本的有效性、可靠性和心理测量特性。
共有280名年轻男性（14 - 20岁）（平均年龄±标准差：17.22±1.8岁）参与研究，其中包括过度游戏玩家和正常受试者。他们回答了VAT、视觉模拟量表（VAS）和康纳 - 戴维森心理韧性量表（CD - RISC）。VAT先进行翻译，然后再回译。为测试可靠性，我们使用了克朗巴哈α系数、分半法和古特曼法。此外，还测试了聚合效度和区分效度，以检验VAT翻译版本的结构效度。
总量表的克朗巴哈α系数为0.81。将问题分成两半后，这两半的克朗巴哈α系数分别为0.71和0.69。计算出六个古特曼λ系数，最小值为0.75，最大值为0.82，均表明测试具有良好的可靠性。通过测试VAT与VAS之间的相关性来检验聚合效度。皮尔逊相关系数为0.73，表明这两个因素之间存在强相关性（P<0.001）。为测试区分效度，检验了VAT与CD - RISC之间的关联，结果显示这些量表之间无相关性（r = -0.157；P = 0.09）。
VAT的波斯语翻译版本有效且可靠，具有与原始版本相似的可接受特性，适用于研究和临床应用。
