摘要

研究以探索性和驗證性因素分析，檢驗貝特非語文智力測驗第二版之因素結構的模式適合度。 從2001年 1月至2002年 2月共收集 125 位輕中度智能障礙者為研究對象，平均年齡為 20.8 歲，標準差 3.7 歲，年齡範圍 16-37歲；平均教育程度為 10.9 年，標準差 1.6 年，年級範圍 6-12 年。結果顯示貝特II非語文智力測驗的潛在因素結構屬於階級模式，亦即非語文智商可以分成知覺速度與觀念推理兩個因素。知覺速度是由走迷津、符號替代與文書檢查等三個分測驗所構成；觀念推理則包括紙形板、圖畫補充及謬誤圖畫等三個分測驗。 智能障礙者在知覺速度因素的整體答對率顯著高於觀念推理因素的整體答對率。

The latent structure of the Revised Beta Examination-Second Edition (Beta-II) was examined in 125 adolescents and adults with mild to moderate mental retardation during the period from January, 2001, through February, 2002. The mean age of the sample was 20.8 (SD = 3.7) and ranged from 16 to 37 years. Years of education completed ranged from 6 to 12 years (M = 10.9, SD = 1.6). The results of the confirmatory factor analysis suggest that a hierarchical model with g at the apex and two subordinate factors Perceptual Speed and Conceptual Reasoning provides an adequate account of the theoretical components underlying the Beta-II IQ, which are robust across sex and levels of mental retardation. Perceptual Speed comprised Mazes, Coding, and Clerical Checking subtests, whereas Conceptual Reasoning was made up of Paper Form Boards, Picture Completion, and Picture Absurdities subtests. Moreover, a significant discrepancy was found in the performances between the Perceptual Speed and Conceptual Reasoning dimensions, with the raw percentage correct scores in the Perceptual Speed higher than those of the Conceptual Reasoning.
