The Outpatient Physical Therapy Improvement in Movement Assessment Log (OPTIMAL) is a self-report instrument developed to measure the ability to perform mobility actions.
To validate a Spanish version of the OPTIMAL instrument.
Cross-cultural adaptation and validation study.
Primary and specialized outpatient care settings.
Three hundred seven patients beginning physical therapy treatment and 30 subjects from the general population.
A 2-part study was designed based on guidelines for cultural adaptation of patient-reported outcome measures.
Reliability was estimated by internal consistency (Cronbach α), SE of measurement, and test-retest reliability (intraclass correlation coefficient) at 2 weeks. Confirmatory factor analysis was performed to examine structural validity. The association with the Physical Functioning Subscale was assessed with Spearman correlation coefficients. OPTIMAL scores across different groups were compared with Mann-Whitney U and Kruskal-Wallis tests. Effect size, standardized response mean, and minimal detectable change were determined for responsiveness.
The Spanish version of the OPTIMAL instrument showed a similar structure to the original English questionnaire. Cronbach α was 0.95 for the difficulty and confidence scales. Intraclass correlation coefficient was 0.91 (95% CI 0.87-0.94) for the difficulty scale and 0.90 (95% CI 0.85-0.93) for the confidence scale. The SE of measurement was 5.11 for the difficulty scale and 6.54 for the confidence scale. The association with the Physical Functioning Subscale was strong and significant (P < .001). The 2 scales showed significantly different scores for each of the established patient groups. The effect size was 0.61 (95% CI 0.48-0.74) for the difficulty scale and 0.53 (95% CI 0.38-0.69) for the confidence scale. The standardized response mean was 0.97 (95% CI 0.78-1.13) for the difficulty scale and 0.76 (95% CI 0.48-1.01) for the confidence scale. The minimal detectable change, of a possible score of 100, was 14.2 for the difficulty scale and 18.1 for the confidence scale.
The Spanish version of the OPTIMAL has appropriate reliability, validity, and responsiveness and it is an adequate self-report instrument for the assessment of mobility actions.

门诊物理治疗运动评估日志（OPTIMAL）是一种自我报告工具，旨在衡量患者进行移动动作的能力。
验证 OPTIMAL 工具的西班牙语版本。
跨文化适应和验证研究。
初级和专门的门诊护理环境。
307 名开始物理治疗的患者和 30 名普通人群中的受试者。
根据患者报告结果测量的文化适应指南设计了 2 部分研究。
西班牙语版 OPTIMAL 工具表现出与原始英语问卷相似的结构。困难和信心量表的 Cronbach α 分别为 0.95。困难量表的组内相关系数为 0.91（95%置信区间为 0.87-0.94），信心量表为 0.90（95%置信区间为 0.85-0.93）。困难量表的测量标准误差为 5.11，信心量表为 6.54。与身体机能子量表的相关性很强且显著（P<0.001）。两个量表在每个既定的患者组中都显示出明显不同的评分。困难量表的效应量为 0.61（95%置信区间为 0.48-0.74），信心量表为 0.53（95%置信区间为 0.38-0.69）。困难量表的标准化反应均值为 0.97（95%置信区间为 0.78-1.13），信心量表为 0.76（95%置信区间为 0.48-1.01）。可能得分为 100 分的最小可检测变化，困难量表为 14.2，信心量表为 18.1。
OPTIMAL 的西班牙语版本具有适当的可靠性、有效性和反应性，是评估移动动作的自我报告工具。
