The Victorian Institute of Sport Assessment (VISA) questionnaire model is based on item response theory using a graded response (responses reflect increasing difficulty). The purpose of the VISA-G is to monitor patient outcomes and evaluate treatment strategies for people with greater trochanteric pain syndrome (GTPS). The primary aim of the current study was to translate and culturally adapt the VISA-G into a Danish context (DK) through forward and back translation and cognitive interviews. The second aim was to establish test-retest reliability and face validity of the VISA-G into a Danish context (DK). No major disagreements were observed between the original and translated versions of the questionnaire. A total of 58 heterogenous asymptomatic, and 49 symptomatic respondents (response rate: 92% and 78% respectively) completed the VISA-G.DK twice, 1 week apart. The VISA-G.DK had excellent internal consistency (Cronbach's alpha: asymptomatic = 0.86; symptomatic = 0.98). The test-retest reliability was excellent for the total score: ICC: 0.961 (95% CI [0.933-0.978]). Standard Error Measurement was calculated to be 0.6. Bland-Altman plots showed no significant or relevant differences from test to retest in the total score with mean differences below 1 (0.61). The minimal detectable change was 3.17 for both groups. The VISA-G.DK was found to be valid, reliable and acceptable for use in the Danish population.
维多利亚体育评估研究所（VISA）问卷模型基于项目反应理论，采用等级反应（反应反映难度增加）。VISA-G的目的是监测大转子疼痛综合征（GTPS）患者的治疗效果并评估治疗策略。本研究的主要目的是通过正向翻译、反向翻译和认知访谈，将VISA-G翻译成丹麦语并进行文化调适。第二个目的是在丹麦语环境（DK）中建立VISA-G的重测信度和表面效度。问卷的原始版本和翻译版本之间未观察到重大分歧。共有58名异质性无症状受访者和49名有症状受访者（回复率分别为92%和78%）完成了两次VISA-G.DK，间隔1周。VISA-G.DK具有出色的内部一致性（克朗巴哈系数：无症状组=0.86；有症状组=0.98）。总分的重测信度极佳：组内相关系数（ICC）：0.961（95%置信区间[0.933 - 0.978]）。计算得出测量标准误为0.6。布兰德-奥特曼图显示，总分重测时无显著或相关差异，平均差异低于1（0.61）。两组的最小可检测变化均为3.17。结果发现，VISA-G.DK在丹麦人群中使用有效、可靠且可接受。
