Abstract

Objective: We conducted two empirical studies (in a cross-sectional and a longitudinal design) with the aim at establishing normative data (including norms for strategy use [i.e., clustering and switching strategies] and performance over time), and examining the convergent validity, the test-retest reliability (3-4 wks interval) and the changes in performance with practice (1 year interval) of the different verbal fluency (VF) quantitative and qualitative scores in Spanish-speaking children and adolescents.

Method: In S1 (n = 620 6- to 15-year-old Spanish-speaking children and adolescents), MANCOVA and Pearson's correlations were employed. In S2 (n = 148 6- to 12-year-old Spanish-speaking children), intraclass correlation coefficient (ICC), paired t-tests, and Confirmatory Factor Analysis (CFA) were used.

Results: S1 results showed an age effect on all VF measures (quantitative and qualitative). The number of switches/clusters was more related to total word productivity and to executive functions (EF) than the mean cluster size. In S2, a significant increase in phonological VF performance was observed on number of switches and word productivity scores from baseline (Time 1) to repeat testing at Time 2. Practice effects were observed at Time 3 on all measures except for semantic and phonological mean cluster size. Test-retest reliability coefficients at Time 2 for number of clusters and switches, but not for mean cluster size, fell in the moderate range, ranging from ICCs .61 to ICCs .81. Test-retest reliability coefficients for total word productivity were higher (ICCs above .80) and stronger when testing as a unity with CFA methods (ϕ=.94, p < .001).

Conclusions: These data may be relevant for informing the neuropsychological assessment of spontaneous cognitive flexibility in children with typical development (TD) and those with developmental or acquired disorders.

西班牙语儿童言语流利性总体表现、聚类和转换的规范、收敛有效性、重测可靠性和练习效果。
研究目的我们进行了两项实证研究(横向和纵向设计),目的是建立标准数据(包括策略使用标准[即聚类和转换策略]和随时间变化的表现),并检验西班牙语儿童和青少年不同言语流利性(VF)定量和定性得分的收敛有效性、重测可靠性(间隔 3-4 周)和随练习表现的变化(间隔 1 年):在 S1(n = 620 名 6 至 15 岁讲西班牙语的儿童和青少年)中,采用了 MANCOVA 和皮尔逊相关性。在 S2(n = 148 名 6 至 12 岁讲西班牙语的儿童)中,采用了类内相关系数(ICC)、配对 t 检验和确证因子分析(CFA):S1 结果显示,年龄对所有 VF 测量(定量和定性)都有影响。与平均聚类大小相比,切换/聚类数量与总词汇量和执行功能(EF)的关系更为密切。在 S2 中,从基线(时间 1)到时间 2 的重复测试,语音 VF 的转换次数和单词效率得分都有明显提高。除了语义学和语音学的平均聚类大小外,在第 3 次测试中,所有测量指标都观察到了练习效应。第 2 次测试时,词簇数量和切换次数的重测信度系数处于中等水平,从 ICCs .61 到 ICCs .81 不等。总词汇生产率的重测信度系数更高(ICCs 高于.80),并且在使用 CFA 方法进行统一测试时更强(j=.94,p <.001):这些数据可能有助于对典型发育(TD)儿童和发育障碍或后天失调儿童的自发认知灵活性进行神经心理学评估。

期刊介绍: The Clinical Neuropsychologist (TCN) serves as the premier forum for (1) state-of-the-art clinically-relevant scientific research, (2) in-depth professional discussions of matters germane to evidence-based practice, and (3) clinical case studies in neuropsychology. Of particular interest are papers that can make definitive statements about a given topic (thereby having implications for the standards of clinical practice) and those with the potential to expand today’s clinical frontiers. Research on all age groups, and on both clinical and normal populations, is considered.
