摘要

根據細緻加工可能性模型，決定態度改變路徑的條件有二：個人捲入事件的程度和個體加工相關信息的能力。本研究以當事人對咨詢會談中咨詢師所傳達信息的理解能力為相關信息加工能力的操作定義，在真實咨詢情境中檢驗了細緻加工可能性模型的效度。使用咨詢師評定表、語意區分態度量表、想法列表協議，以及自編當事人信息理解程度評定表，對70位當事人進行測量。測量變量包括：當事人對咨詢師可信性的知覺、當事人對咨詢師所提供信息的態度，以及當事人對信息的理解能力。根據細緻加工可能性模型的假設，以當事人對信息的理解能力為調節變量，調節咨詢師可信性對當事人態度的影響，理解能力愈高，可信性對態度的影響愈小。研究結果顯示：當事人信息理解能力的調節效應顯著。調節效應的具體形式為：當事人對信息的理解能力愈高，可信性對態度的影響愈明顯。本文亦討論了研究中存在的共同方法偏差及其影響。

關鍵詞：細緻加工可能性模型；調節效應；咨詢師可信性；當事人信息理解能力

Abstract

According to the Elaboration Likelihood Model (ELM), there are two conditions (high personal involvement and the ability to process relevant information) that determine which route individuals will choose in changing attitude. With operationally defining the ability to process issue-relevant information as the client’s ability in understanding the information delivered in counseling sessions, in this study, the validity of ELM application in counseling was examined in a study using data collected from real counseling sessions in China. A total of 70 clients completed Thoughts-Listing Protocol, Semantic Differentials, and Counselor Rating Form – Short, which assessed, respectively, their ability in understanding relevant information, their attitude toward the information delivered in counseling sessions, and their perception on therapist’s credibility. The results of hierarchical multilevel regression showed that the moderator effect of clients’ ability in understanding was significant. That is, a client’s ability of understanding the information delivered by the therapist significantly moderated the relationship between the therapist’s credibility and the client’s attitude. A larger effect of therapist’s credibility on client’s attitude was revealed for the participants at a higher level of ability in understanding than that for those with a lower level of ability. Finally, the authors discussed the limitations (e.g., common method bias) in the present study.
