To investigate the test-retest stability of a standardized version of Nelson's (1976) Modified Card Sorting Test (MCST) and its relationships with demographic variables in a sample of healthy older adults.
A standard card order and administration were devised for the MCST and administered to participants at an initial assessment, and again at a second session conducted a minimum of six months later in order to examine its test-retest stability. Participants were also administered the WAIS-R at initial assessment in order to provide a measure of psychometric intelligence.
Thirty-six (24 female, 12 male) healthy older adults aged 52 to 77 years with mean education 12.42 years (SD = 3.53) completed the MCST on two occasions approximately 7.5 months (SD = 1.61) apart. Stability coefficients and test-retest differences were calculated for the range of scores. The effect of gender on MCST performance was examined. Correlations between MCST scores and age, education and WAIS-R IQs were also determined.
Stability coefficients ranged from .26 for the percent perseverative errors measures to .49 for the failure to maintain set measure. Several measures were significantly correlated with age, education and WAIS-R IQs, although no effect of gender on MCST performance was found.
None of the stability coefficients reached the level required for clinical decision making. The results indicate that participants' age, education, and intelligence need to be considered when interpreting MCST performance. Normative studies of MCST performance as well as further studies with patients with executive dysfunction are needed.
在健康老年人样本中,研究纳尔逊(1976年)修订卡片分类测试(MCST)标准化版本的重测稳定性及其与人口统计学变量的关系。
为MCST设计了标准的卡片顺序和施测方式,并在初次评估时对参与者进行施测,在至少六个月后的第二次测试中再次施测,以检验其重测稳定性。在初次评估时还对参与者进行了韦氏成人智力量表修订版(WAIS-R)测试,以提供心理测量智力的指标。
36名(24名女性,12名男性)年龄在52至77岁之间、平均受教育年限为12.42年(标准差=3.53)的健康老年人,在两次间隔约7.5个月(标准差=1.61)的测试中完成了MCST。计算了分数范围内的稳定性系数和重测差异。检验了性别对MCST表现的影响。还确定了MCST分数与年龄、受教育程度和WAIS-R智商之间的相关性。
稳定性系数范围从持续性错误百分比测量的0.26到无法保持定势测量的0.49。尽管未发现性别对MCST表现有影响,但几项测量与年龄、受教育程度和WAIS-R智商显著相关。
没有一个稳定性系数达到临床决策所需的水平。结果表明,在解释MCST表现时需要考虑参与者的年龄、受教育程度和智力。需要对MCST表现进行规范性研究以及对执行功能障碍患者进行进一步研究。
