The Schizophrenia Caregiver Questionnaire (SCQ) was developed to evaluate the state of family members caring for schizophrenics. Our study aimed to construct a Japanese version of the SCQ (J-SCQ) based on its English version and verify its reliability and validity. We conducted forward and backwards translations and cognitive debriefing to draw up the J-SCQ. A total of 1229 survey sheets were mailed, together with the Japanese versions of the Medical Outcomes Study Short-Form version 2 (SF-12v2) and World Health Organization Quality of Life Scale (WHOQOL-26) questionnaires. A total of 305 survey sheets (valid response rate: 68.2%) were analyzed. The Cronbach's alpha coefficients of various supra-domains and subdomains of the J-SCQ were over 0.71, establishing its internal consistency. Pearson's correlation coefficients between the various domains of the SF-12v2 and WHOQOL-26 was used to establish concurrent validity. The results show that the J-SCQ may be a useful Japanese questionnaire that can compare Japanese caregivers to those across different countries and measure the effects of support and intervention provided to caregivers.
精神分裂症照顾者问卷（SCQ）旨在评估照顾精神分裂症患者的家庭成员的状况。我们的研究旨在基于英文版本构建日文版的SCQ（J-SCQ），并验证其信效度。我们进行了正向和反向翻译以及认知反馈，以制定J-SCQ。总共邮寄了1229份调查问卷，同时附上了医学结局研究简表第2版（SF-12v2）和世界卫生组织生活质量量表（WHOQOL-26）的日文版问卷。共分析了305份调查问卷（有效回复率：68.2%）。J-SCQ各超领域和子领域的Cronbach's alpha系数均超过0.71，表明其内部一致性良好。使用SF-12v2和WHOQOL-26各领域之间的Pearson相关系数来建立同时效度。结果表明，J-SCQ可能是一份有用的日文问卷，可用于比较日本照顾者与不同国家的照顾者，并衡量为照顾者提供的支持和干预的效果。
