To evaluate the preliminary validity and reliability of the myTREEHOUSE Self-Concept Assessment for children with cerebral palsy (CP) aged 8 to 12 years.
The myTREEHOUSE Self-Concept Assessment includes 26 items divided into eight domains, assessed across three Performance Perspectives (Personal, Social, and Perceived) and an additional Importance Rating. Face and content validity was assessed by semi-structured interviews with seven expert professionals regarding the assessment construct, content, and clinical utility. Reliability was assessed with 50 children aged 8 to 12 years with CP (29 males, 21 females; mean age 10y 2mo; Gross Motor Function Classification System [GMFCS] level I=35, II=8, III=5, IV=1; mean Wechsler Intelligence Scale for Children - Fourth Edition [WISC-IV]=104), whose data was used to calculate internal consistency of the scale, and a subset of 35 children (20 males, 15 females; mean age 10y 5mo; GMFCS level I=26, II=4, III=4, IV=1; mean WISC-IV=103) who participated in test-retest reliability within 14 to 28 days.
Face and content validity was supported by positive expert feedback, with only minor adjustments suggested to clarify the wording of some items. After these amendments, strong internal consistency (Cronbach's α 0.84-0.91) and moderate to good test-retest reliability (intraclass correlation coefficient 0.64-0.75) was found for each component.
The myTREEHOUSE Self-Concept Assessment is a valid and reliable assessment of self-concept for children with CP aged 8 to 12 years.
评估myTREEHOUSE自我概念评估工具对8至12岁脑瘫（CP）儿童的初步效度和信度。
myTREEHOUSE自我概念评估包括26个项目，分为八个领域，从三个表现视角（个人、社会和感知）以及一个额外的重要性评级进行评估。通过与七位专家就评估结构、内容和临床实用性进行半结构化访谈来评估表面效度和内容效度。对50名8至12岁的CP儿童（29名男性，21名女性；平均年龄10岁2个月；粗大运动功能分类系统[GMFCS]：I级=35名，II级=8名，III级=5名，IV级=1名；韦氏儿童智力量表第四版[WISC-IV]平均得分=104）进行信度评估，其数据用于计算该量表的内部一致性，另有35名儿童（20名男性，15名女性；平均年龄10岁5个月；GMFCS：I级=26名，II级=4名，III级=4名，IV级=1名；WISC-IV平均得分=103）在14至28天内参与重测信度评估。
专家的积极反馈支持了表面效度和内容效度，仅建议进行一些小调整以澄清某些项目的措辞。经过这些修改后，各分量表均具有较强的内部一致性（克朗巴哈α系数为0.84 - 0.91）和中等至良好的重测信度（组内相关系数为0.64 - 0.75）。
myTREEHOUSE自我概念评估是对8至12岁CP儿童自我概念的有效且可靠的评估。
