我们通过评估青少年对基于多伦多述情障碍量表-20（TAS-20）的自我报告问卷的反应，研究了青少年情绪意识的发展方面。对TAS-20的项目进行了修改，使其更容易被青少年理解，并增加了9个与想象力有限有关的新项目。本研究采用日本语言能力测验和青少年多维移情量表进行测量，以检验其同时效度。202名正常青少年和32名有心身和/或行为问题的青少年患者参加了这项研究。80名初中生也参加了单独的重测信度测试。经过探索性和验证性因素分析后，提取了13个项目，并确定了4个核心因素，在所产生的量表：识别感觉困难（DIF），描述感觉困难（DDF），外部导向思维（EOT）和压缩的想象能力（CIC）。有趣的是，多维共情量表得分与DIF和DDF呈正相关，但与EOT和CIC呈负相关。较高的DDF分数与较高的日语能力相关。无论语言能力如何，女性的DIF/DDF评分均高于男性。重测信度系数显著。患者组的DIF评分显著高于正常学生。目前的研究结果表明，在识别和描述的感觉的主观困难与移情和语言能力。发展方面的情绪意识，本文所述的表明，述情障碍的自我报告问卷必须仔细构建和检查，即使是成年人。
We examined developmental aspects of the emotional awareness of adolescents by evaluating their responses to a self-reported questionnaire based on the Toronto Alexithymia Scale-20 (TAS-20). The items of the TAS-20 were modified to make them more understandable by adolescents, and nine new items related to a limited capacity for imagination were added. The Japanese Linguistic Ability Test and the multi-dimensional empathy scale for adolescents were administered to examine concurrent validity. Two hundred and two normative young adolescents and thirty-two adolescent patients with psychosomatic and/or behavioral problems participated in the study. Eighty junior high school students also participated in a separate examination of test-retest reliability. Thirteen items were extracted after exploratory and confirmatory factor analyses, and four core factors were identified in the resulting scale: Difficulty Identifying Feelings (DIF), Difficulty Describing Feelings (DDF), Externally-Oriented Thinking (EOT) and Constricted Imaginal Capacities (CIC). Interestingly, scores on the multi-dimensional empathy scale correlated positively with DIF and DDF, but negatively with EOT and CIC. Higher DDF scores were associated with higher Japanese linguistic abilities. DIF/DDF scores were higher for females than males, irrespective of linguistic ability. Test-retest reliability coefficients were significant. The patient group showed significantly higher DIF scores than the normative students. The present findings indicated that subjective difficulties in identifying and describing feelings are associated with empathetic and linguistic abilities. The developmental aspect to emotional awareness herein described suggests that self-reported questionnaires for alexithymia must be carefully constructed and examined, even for adults.
