Overview

The purpose of this study is to introduce and bring into the clinical practice new screening tool Coin in the Hand Test for detection of simulating disability or weak results in psychological assessment.

Aim:
The goal of this study was to define the maximal performance in a general and clinical population and to determine the extent to which participants in experimental group are capable of faking weakened performance so that this fraud would not be recognized.

Material and methods:
The test Coin in the Hand Test was studied on a non-psychiatric group of participants (N = 153) to determine the ability to adapt to three different scenarios: 1 = the best possible performance; 2 = acquiring disability pension; 3 = prolonging sick leave. In the second study the test was administered individually to a group of hospitalized psychiatric patients.

Results:
The performance score for each scenario significantly differed suggesting to a good ability of experimental group to adapt to the instruction. The mean performance score for the maximal performance was close to the maximum of 10 points (M = 9,98; SD = 0,13; 9– 10), while for the serious faking it was the lowest (M = 4,87; SD = 2,37; 0–10). Score for moderate faking was found in between the previous two values (M = 6,85; SD = 1,72; 1–10). The results of the individual assessment done on a group of psychiatric patients corresponded with the results of the group with a scenario for the best possible performance.

Conclusion:
The presented very good ability to differentiate between faking and honest individuals is an encouragement for inclusion of this test into the clinical practice.

Key words:
Coin in the Hand Test – malingering – insufficient effort

The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.

The Editorial Board declares that the manuscript met the ICMJE “uniform requirements” for biomedical papers.

测量 - 手测试中的硬币

本研究的目的是引入临床实践中的一种新的筛查工具,在手测试中用于检测模拟残疾或 在手测试中用于检测模拟残疾或心理评估结果较差的硬币。

目标

这项研究的目标是定义一般和临床人群的最大表现,并确定实验组参与者是否有能力欺骗性能下降的程度,从而无法识别这种欺诈。

材料和方法

在非精神科参与者组(N = 153)中研究了手部测试中的测试硬币,以确定适应三种不同场景的能力:1 =最佳性能; 2 =获得残疾养恤金; 3 =延长病假在第二项研究中,试验单独给予一组住院的精神病患者。

结果

每个场景的表现分数显着不同,表明实验组适应指令的良好能力。最高表现的平均表现得分接近10分(M = 9.98; SD = 0.,13; 9 - 10),而对于严重的假冒,则最低(M = 4 ,87; SD = 2.37; 0-10)。在前两个值之间发现中度假的得分(M = 6.85; SD = 1,72; 1-10)。对一组精神病患者进行的个别评估结果与该组的结果相符,并提供了最佳表现的情景。

结论

患者表现出非常好的区分假冒和诚实个体的能力,这是鼓励鼓励将该测试纳入临床实践的鼓励。
