目的评价赌博冲动量表中文版(GUS-C)的信度和效度,为该量表在中国大陆的推广使用提供科学依据。方法采用分层随机抽样方法在辽宁、山东、河南、湖北、湖南、福建6省抽取730名≥18岁中国大陆常住居民进行问卷调查;采用同质性信度、分半信度、重测信度进行信度评价,采用效标关联效度和结构效度进行效度评价。结果项目分析结果表明,GUS-C量表6个条目与其总分相关系数为0.648～0.838,CR值为8.797～29.525(均P<0.01);GUS-C量表总体Cronbach’sα系数、分半信度和重测信度分别为0.834、0.813、0.819,条目间平均相关系数为0.531;赌博相关认知量表(GRCS-C)总分及其赌博期待、控制错觉、预测控制、无力戒赌、解释偏差5个维度得分与GUS-C量表总分的Pearson相关系数为0.359～0.570(均P<0.01),抑郁焦虑压力中文简体版(DASS-21)总分及其抑郁、焦虑、压力3个维度得分与GUS-C量表总分的Pearson相关系数为0.238～0.307(均P<0.01);验证性因素分析结果表明,拟合指标GFI=0.98、AGFI=0.97、CFI=0.99、RFI=0.98、RMSEA=0.053,各条目因素负荷分别为0.81、0.41、0.78、0.88、0.72、0.84;中国大陆居民男性和女性GUS-C量表得分分别为(10.66±7.41)和(9.16±5.62)分,均高于中国台湾居民及在澳华人的(9.18±6.29)和(7.84±4.10)分以及澳大利亚居民的(8.31±4.73)和(6.98±2.41)分,差异均有统计学意义(P<0.01)。结论 GUS-C量表具有较好的信度和效度,可作为中国大陆居民赌博冲动评价的有效工具。
Objective To evaluate the reliability and validity of the Chinese version of the Gamble Impulse Scale (GUS-C) and provide a scientific basis for the promotion and use of the scale in mainland China. Methods Stratified random sampling method was used to conduct questionnaire survey in 730 Chinese mainland residents aged 18 and above in Liaoning, Shandong, Henan, Hubei, Hunan and Fujian provinces. A questionnaire survey was conducted using stratified random sampling method. Degree of reliability evaluation, the validity of the standard-related validity and structural validity evaluation. Results The results of project analysis showed that the correlation coefficient of 6 items in GUS-C scale was 0.648-0.838 and CR was 8.797-29.525 (all P <0.01). The overall Cronbach’s alpha coefficient of GUS-C scale was divided into half Reliability and retest reliability were 0.834, 0.813 and 0.819 respectively, and the average correlation coefficient was 0.531. The score of GRCS-C and its gambling expectation, control illusion and predictive control were unable to quit , And the Pearson correlation coefficient between the five dimensions of explanatory deviation and the total score of GUS-C was 0.359-0.570 (all P <0.01). The total score of DASS-21 and its depression, anxiety, stress The Pearson correlation coefficient between the three dimensions and the GUS-C total score was 0.238-0.307 (all P <0.01). The results of confirmatory factor analysis showed that the fitting index GFI = 0.98, AGFI = 0.97, CFI = 0.99, RFI = 0.98, RMSEA = 0.053, and the load of each item was 0.81,0.41,0.78,0.88,0.72,0.84. The scores of male and female GUS-C in Chinese mainland were (10.66 ± 7.41) and (9.16 ± 5.62) Points higher than those from Taiwan, China residents and Chinese in Australia (9.18 ± 6.29) and (7.84 ± 4.10), respectively, and those in Australia (8.31 ± 4.73) and (6.98 ± 2.41) points, the difference was statistically significant (P <0.01). Conclusion The GUS-C scale has good reliability and validity, which can be used as an effective tool to evaluate the gambling impulse of Chinese residents.
