OBJECTIVES. The present study analyses the internal factor structure of the University of Rhode Island Change Assessment (URICA) Scale in pathological gambling (PG). The scale's association with the clinical profile of patients is also evaluated. METHOD. The factor analysis was based on a sample of 531 men with a DSM-IV diagnosis of pathological gambling. The statistical analysis included confirmatory factor analysis and linear correlation. RESULTS. The analyses confirmed the internal structure obtained for the URICA. The internal consistency was satisfactory (Cronbach's alpha between .74 and .85). The association between URICA scores and the socio-demographic and clinical profile of patients ranged between moderate and weak (R coefficients below .30). Lower motivation was present in 28.4% of cases and it was associated with shorter duration of the disorder, lower severity of the PG symptoms, and high psychopathology. Conclusions. The results support the validity and reliability of the URICA in a Spanish clinical population of pathological gamblers.
目的。本研究分析了罗得岛大学变化评估量表（URICA）在病理性赌博（PG）中的内部因素结构。还评估了该量表与患者临床特征的相关性。方法。该因子分析基于 531 名男性的样本，他们被诊断为 DSM-IV 病理性赌博。统计分析包括验证性因子分析和线性相关。结果。分析证实了 URICA 的内部结构。内部一致性令人满意（Cronbach 的 alpha 在.74 和.85 之间）。URICA 评分与患者的社会人口统计学和临床特征之间的相关性介于中等和较弱之间（R 系数低于.30）。在 28.4%的病例中存在较低的动机，它与疾病持续时间较短、PG 症状严重程度较低和较高的精神病理学相关。结论。研究结果支持 URICA 在西班牙病理性赌博临床人群中的有效性和可靠性。
