To understand potential benefits of exercise in the cystic fibrosis (CF) population, there needs to be accurate methods to quantify it. The Habitual Activity Estimation Scale (HAES) questionnaire has been shown to be a feasible tool to measure physical activity however the reliability and validity have yet to be determined in the CF population.
Fourteen (seven male, seven female) patients aged 16.2 +/- 4.2 years with CF participated in this study. Participants were clinically stable at the time of the study and participating in their habitual physical activity. To assess reliability, patients completed the HAES and a validated 3-day activity diary, and wore an ActiGraph Accelerometer for two consecutive weeks. Validity was assessed by comparing the activity results of each of the three instruments over a single week time period.
ICC estimates of reliability for the HAES, diary, and accelerometer were 0.72 (P < 0.0001), 0.76 (P < 0.0001), 0.63 (P < 0.0001), respectively. Validity analysis indicated that there were significant relationships between the participants' activity results as estimated by the HAES, diary and accelerometer. Further, significant relationships were detected between activity measures when broken into morning, afternoon, or evening periods, and between measures from weekday or weekend days. There were also significant relationships among the three instruments when recording different activity levels (somewhat inactive, somewhat active, and very active).
The findings of this study suggest that the HAES questionnaire is a reliable and valid instrument that can be used to assess activities of varying intensity in patients with CF.
为了解运动对囊性纤维化（CF）患者群体的潜在益处，需要有准确的方法来对其进行量化。习惯性活动评估量表（HAES）问卷已被证明是一种测量身体活动的可行工具，但其在CF患者群体中的信度和效度尚未确定。
14名（7名男性，7名女性）年龄为16.2±4.2岁的CF患者参与了本研究。研究时参与者临床状况稳定，且进行其习惯性身体活动。为评估信度，患者完成HAES问卷和一份经验证的3天活动日记，并连续两周佩戴ActiGraph加速度计。通过比较三种仪器在单周时间内的活动结果来评估效度。
HAES问卷、活动日记和加速度计的信度ICC估计值分别为0.72（P<0.0001）、0.76（P<0.0001）、0.63（P<0.0001）。效度分析表明，HAES问卷、活动日记和加速度计所估计的参与者活动结果之间存在显著关系。此外，在按上午、下午或晚上时段划分的活动测量之间，以及工作日或周末的测量之间，均检测到显著关系。在记录不同活动水平（有些不活跃、有些活跃和非常活跃）时，三种仪器之间也存在显著关系。
本研究结果表明，HAES问卷是一种可靠且有效的工具，可用于评估CF患者不同强度的活动。
