Performance on the Medical Symptom Validity Test (MSVT) was examined in 193 consecutively referred patients aged 8 through 17 years who had sustained a mild traumatic brain injury. A total of 33 participants failed to meet actuarial criteria for valid effort on the MSVT. After accounting for possible false positives and false negatives, the base rate of suboptimal effort in this clinical sample was 17%. Only one MSVT failure was thought to be influenced by litigation. The present results suggest that a sizable minority of children is capable of putting forth suboptimal effort during neuropsychological exam, even when external incentives are not readily apparent. The MSVT appears to have good potential value as an objective measure for detecting symptom invalidity in school-age youth.
193 名连续就诊的 8 至 17 岁轻度创伤性脑损伤患者进行了医学症状有效性测验（MSVT）的表现测试。共有 33 名参与者未能通过 MSVT 有效努力的统计标准。在考虑了可能的假阳性和假阴性后，该临床样本中表现不佳的努力的基础率为 17%。仅认为一个 MSVT 失败受到诉讼的影响。目前的结果表明，相当一部分儿童在进行神经心理学检查时能够表现出不佳的努力，即使外部激励并不明显。MSVT 似乎具有很好的潜在价值，可以作为检测学龄期青少年症状无效的客观衡量标准。
