To examine changes in speed of information processing on a modification of the Stroop color-naming task following cognitive-behavior therapy (CBT) and to evaluate whether changes are associated with word type, treatment condition, or treatment response.
Subjects were 98 women aged between 17 and 45 years with a current primary diagnosis of bulimia nervosa who were participating in a randomized clinical trial evaluating CBT. Data were available on all relevant variables for 98 women. Speed of information processing was assessed at pretreatment and posttreatment using a modification of the Stroop color-naming paradigm.
Significant main effects were found for the factors time (pretreatment vs. posttreatment) and word type (food/body words vs. color words, food/body words vs. control words). Predicted interactions between time and word type were not identified.
Changes in information processing speed over treatment were not specifically associated with word type, treatment condition, or treatment response. Consequently, the utility of the modified Stroop paradigm as a measure of change over time for bulimia nervosa is questioned.
在对斯特鲁普颜色命名任务进行修改后,研究认知行为疗法(CBT)后信息处理速度的变化,并评估这些变化是否与单词类型、治疗条件或治疗反应相关。
研究对象为98名年龄在17至45岁之间、目前初步诊断为神经性贪食症的女性,她们参与了一项评估CBT的随机临床试验。98名女性的所有相关变量数据均可用。在治疗前和治疗后,使用对斯特鲁普颜色命名范式的修改版本来评估信息处理速度。
发现时间(治疗前与治疗后)和单词类型(食物/身体相关词汇与颜色词汇、食物/身体相关词汇与对照词汇)这两个因素有显著的主效应。未发现时间和单词类型之间的预测交互作用。
治疗过程中信息处理速度的变化与单词类型、治疗条件或治疗反应并无特定关联。因此,修改后的斯特鲁普范式作为神经性贪食症随时间变化的一种测量方法的效用受到质疑。
