Reliability estimates were determined for 24 moderately mentally retarded adult males on three psychomotor tasks. For four consecutive days measures were taken on reaction time, auditory and visual, 15 trials daily for each; grip strength, dominant and non-dominant hand, two trials daily for each; and standing long jump, three trials daily. Analyses of variance, adjusted for day-to-day trend, were applied to the data. Intraclass reliability coefficients for both dominant (R = .96) and non-dominant (R = .94) hand-grip strength were high. The reaction time scores for both the auditory (R = .87) and visual (R = .83) data were moderately reliable. A low reliability coefficient (R = .49) was obtained for the standing long jump.
对24名中度智力障碍成年男性在三项心理运动任务上进行了信度估计。连续四天对反应时间（包括听觉和视觉反应时间，每天每项进行15次试验）、握力（优势手和非优势手，每天每项进行2次试验）以及立定跳远（每天进行3次试验）进行测量。对数据应用了经日常趋势调整的方差分析。优势手（R = 0.96）和非优势手（R = 0.94）握力的组内信度系数都很高。听觉（R = 0.87）和视觉（R = 0.83）数据的反应时间得分具有中等信度。立定跳远获得了较低的信度系数（R = 0.49）。
