明尼苏达州休闲时间身体活动问卷（LTPA）的准确性（MRFIT中使用的非职业活动的1年调查）在78名年龄20-59岁的男性和女性中进行了研究，通过将调查结果与一年内获得的以下测量结果进行比较：6个48小时体力活动记录，14个48小时Caltrac加速度计读数（Caltrac），进行14次为期4周的LTPA问卷（FWH）; 3次V-02峰值测定和体脂百分比（% BF）。LTPA问卷显示：与% BF（r = -0.24）和V-02峰值（r = 0.47）之间存在弱至中度相关性;与Caltrac读数之间存在弱相关性，表示为Met.minutes.day（-1）（r = 0.23）;与FWH报告的相应活动有很强的关联;中度关联与体力活动记录中报告的总活动和重度活动有关，但与中度和轻度活动无关。此外，发现几种LTPA要么代表性不足，要么目前未包括在明尼苏达州LTPA量表中。它的结论是，虽然验证结果被发现是相当不错的，几个可能的改进被确定，这应该提高明尼苏达州LTPA问卷评估习惯性体力活动的准确性。
The accuracy of the Minnesota Leisure Time Physical Activity (LTPA) Questionnaire (a 1-year survey of non-occupational activity used in MRFIT) was studied in 78 men and women, age 20-59 years, by comparing survey results to the following measures obtained over a year's duration: six 48-hour physical activity records; fourteen 48-hour Caltrac accelerometer readings (Caltrac); 14 administrations of a 4-week version of the LTPA Questionnaire (FWH); 3 V-02peak determinations and percent body fat (% BF). The LTPA Questionnaire demonstrated: weak to moderate associations with % BF (r = -0.24) and with V-02peak (r = 0.47); a weak association with Caltrac readings expressed as Met.minutes.day(-1) (r = 0.23); strong associations with corresponding activities reported on the FWH; and moderate associations with total and heavy activities reported in the physical activity record, but no associations with moderate and light activities. Furthermore, several types of LTPA were found to be either under-represented or not currently included in the Minnesota LTPA Questionaire. It is concluded that although validation results were found to be quite good, several possible refinements were identified, which should improve the accuracy of the Minnesota LTPA Questionnaire is assessing habitual physical activity.
