This study examined the capacity of the Seashore Rhythm Test (SRT) and the Speech-Sounds Perception Test (SSPT) to detect insufficient effort in a clinical sample. Forty-six participants with financially compensable mild head injury who obtained scores indicative of insufficient effort on multiple measures were compared to 49 participants with brain injury who were not involved in litigation. Receiver operating characteristic (ROC) curve analysis indicated that both the SRT (AUC = .84) and SSPT (AUC = .80) were significant (p < .001) predictors of insufficient effort. Maximizing sensitivity and specificity, the optimal cutoff scores were 8 errors on the SRT and 10 errors on the SSPT. Combining both variables into a logistic regression function increased the diagnostic efficiency.
本研究考察了海岸节律测验（SRT）和言语声音感知测验（SSPT）在临床样本中检测努力不足的能力。将46名因轻度头部受伤获得经济赔偿且在多项测量中得分表明努力不足的参与者与49名未卷入诉讼的脑损伤参与者进行比较。受试者工作特征（ROC）曲线分析表明，SRT（曲线下面积[AUC]=0.84）和SSPT（AUC=0.80）都是努力不足的显著预测指标（p<0.001）。为使敏感性和特异性最大化，SRT的最佳临界分数为8个错误，SSPT为10个错误。将两个变量纳入逻辑回归函数可提高诊断效率。
