Objective To test the reliability and validity of the Physical Activity Scale for the Elderly(PASE)(Chinese version) in old patients with chronic obstructive pulmonary disease(COPD),so as to provide an effective tool for evaluating physical activity of older patients with COPD in China.Methods According to the inclusion criteria,201 patients with COPD receiving treatment in outpatient of Tianjin First Center Hospital from March 2015 to May 2016 were selected as research subjects by convenience sampling method.General Situation Questionnaire,PASE in Chinese version(PASE-C),International Physical Activity Questionnaire-short(IPAQ-S),36-item Short-Form Health Survey Questionnaire(SF-36) and Self-Efficacy for Managing Chronic Disease 6-Item Scale(SES6) were applied to collect patients′ information.A total of 201 questionnaires were sent out and 194 valid questionnaires were collected.The effective response rate was 96.5%.By convenience sampling method,40 patients were selected to carry pedometer and record data for seven consecutive days,and they would complete PASE-C again.Results The Cronbach′s α coefficient of PASE-C was 0.725.The test-retest reliability of PASE-C was 0.980,the test-retest reliability of leisure time activities was 0.944,the test-retest reliability of household activities was 0.978,and the test-retest reliability of occupational activities was 0.970(P<0.001).In the PASE-C,the Item-Content Validity Index(I-CVI) of leisure time activities was 1.00,I-CVI of household activities was from 0.83 to 1.00,and I-CVI of occupational activities was 0.83;the Scale-Content Validity Index/Universal Agreement(S-CVI/UA) was 0.80,Scale-Content Validity Index/Average(S-CVI/Ave) was 0.97.The total steps of pedometer were positively correlated with the total score of PASE-C(r=0.578,P<0.001).The total scores of PASE-C and IPAQ-S were positively correlated(rs=0.698,P<0.001).The total score of PASE-C was negatively correlated with mMRC score and DOSE index,and positively correlated with total score of SF-36,and score of physiological function(PF),role of physiology(RP),general health status(GH),vitality(VT),social function(SF),role of emotion(RE),mental health(MH),and total score of SES6(P<0.05).Conclusion The PASE-C has good validity and reliability,which can be applied into the measurement of physical activity of old patients with COPD in China.%目的 评价中文版老年人体力活动量表(PASE)在老年慢性阻塞性肺疾病(COPD)患者中的信效度,以期为我国老年COPD患者提供有效的体力活动测评工具.方法 采用便利抽样法,选取2015年3月-2016年5月在天津市第一中心医院门诊接受治疗的符合纳入标准的COPD患者201例为调查对象.采用一般情况调查表、中文版PASE、国际体力活动问卷短卷(IPAQ-S)、健康调查简表(SF-36)、慢性病管理自我效能量表(SES6)对其进行调查.共发放问卷201份,回收有效问卷194份,有效回收率为96.5%.从194例患者中采用便利抽样法抽取40例携带计步器7 d,记录7 d的计步器数据,并再次让患者填写中文版PASE.结果 中文版PASE的Cronbach′s α系数为0.725.中文版PASE的重测信度为0.980,休闲性体力活动重测信度为0.944,家务性体力活动重测信度为0.978,职业性体力活动重测信度为0.970(P<0.001).中文版PASE中,休闲性体力活动的条目水平的内容效度指数(I-CVI)为1.00,家务性体力活动的I-CVI为0.83~1.00,职业性体力活动的I-CVI为0.83;中文版PASE的全体一致量表水平的内容效度指数(S-CVI/UA)=0.80,平均量表水平的内容效度指数(S-CVI/Ave)=0.97.计步器总步数与重测中文版PASE总分呈正相关(r=0.578,P<0.001).中文版PASE总分与IPAQ-S总分呈正相关(rs=0.698,P<0.001).中文版PASE总分与mMRC评分、DOSE指数呈负相关,与SF-36总分、生理机能(PF)得分、生理职能(RP)得分、一般健康状况(GH)得分、精力(VT)得分、社会功能(SF)得分、情感职能(RE)得分、精神健康(MH)得分、SES6总分呈正相关(P<0.05).结论 中文版PASE具有良好的信效度,适合在中国老年COPD患者中应用.
