This study aimed to validate the revised Short Questionnaire to Assess Health-Enhancing Physical Activity (SQUASH) to measure sedentary activity in post-liver-transplant patients. The proposed scale could be useful for transplantation nurses to assess and modify sedentary lifestyles and increase physical activity.
The SQUASH was modified to include items on sitting time and light-intensity physical activity (LPA-SQUASH). A pilot study was conducted with 20 liver transplant patients, and an expert panel validated the scale contents. Then, post-liver-transplant outpatients at a Japanese university hospital participated in the main study (September-October 2020), in which questionnaires were mailed twice to assess test-retest reliability, and accelerometers used to establish criterion validity. Intra-class correlation coefficients (ICC) were calculated for test-retest reliability. Spearman correlations and Bland-Altman plots were used to assess validity and measurement error.
In total, 173 participants returned the questionnaires, and 106 and 71 completed the reliability and validation studies, respectively. The range of LPA-SQUASH correlation coefficients for test-retest was .49-.58. ICCs ranged from .72 to .80 for items other than leisure. Accelerometer data and the LPA-SQUASH total physical activity amount and light-intensity physical activity correlated moderately.
We modified the SQUASH, which was developed to measure physical activity in healthy adults, to assess light-intensity physical activity in post-liver-transplant patients. The LPA-SQUASH showed acceptable validity and reliability. The questionnaire may be used by transplantation nurses to examine light-intensity physical activity content/duration, deliver patient education considering patients' sedentary lifestyle, and facilitate goal setting for physical activity interventions to prevent metabolic syndrome.
本研究旨在验证修订后的简短评估健康促进体力活动问卷（SQUASH），以测量肝移植后患者的久坐活动。该量表可用于移植护士评估和改变久坐生活方式并增加体力活动。
SQUASH 进行了修改，纳入了久坐时间和低强度体力活动（LPA-SQUASH）的项目。对 20 名肝移植患者进行了试点研究，并由专家小组验证了量表内容。然后，日本一所大学医院的肝移植门诊患者参加了主要研究（2020 年 9 月至 10 月），通过邮寄问卷两次评估测试-重测信度，并使用加速度计建立效标效度。计算了测试-重测信度的组内相关系数（ICC）。使用 Spearman 相关系数和 Bland-Altman 图评估效度和测量误差。
共有 173 名参与者返回了问卷，106 名和 71 名分别完成了可靠性和验证研究。LPA-SQUASH 测试-重测相关性的范围为.49-.58。除休闲外，其他项目的 ICC 范围为.72 至.80。加速度计数据与 LPA-SQUASH 总体力活动量和低强度体力活动呈中度相关。
我们修改了 SQUASH，该问卷最初是为测量健康成年人的体力活动而开发的，现用于评估肝移植后患者的低强度体力活动。LPA-SQUASH 具有可接受的有效性和可靠性。移植护士可以使用该问卷检查低强度体力活动的内容/持续时间，根据患者的久坐生活方式提供患者教育，并促进设定体力活动干预目标，以预防代谢综合征。
