Description
本研究では,約半数のADHDの成人に併発する症状である成人のSCT症状を測定する尺度を開発し,妥当性を検討した。この新たな尺度の狙いは,既存の尺度の項目が抑うつと類似しているために抑うつとの弁別性が乏しい問題を克服することであった。文献のレビューによってSCT項目が選定され,専門家によって内容的妥当性の検討が行われた。これらの項目は抑うつ気分でないときの状況について回答されるものであった。大学生471名が質問紙に回答し,因子分析によって項目の選定が行われた。ジョイント因子分析によって,本SCT尺度は抑うつからの十分な弁別性を有していることが示された。最終的なSCT尺度(9項目)は,収束的妥当性,弁別的妥当性,内的一貫性の高さが示された。
Description Alternative
This study developed and validated a measure of sluggish cognitive tempo (SCT) for adults, which is a comorbid symptom in about half of the adults with ADHD. The aim of this new measure was to overcome the shortcoming of existing scales to discriminate SCT from depression due to contaminated items. The items to measure SCT were identified by a literature review, and their content validity was evaluated by experts. The items were rated in reference to situations when the participants were not depressed. Responses of 471 undergraduate students were used for factor analyses to help select the items. The results of a joint factor analysis, combining depression items and SCT items, showed that this new measure of SCT for adults demonstrated a good ability to discriminate SCT from depression. The resultant 9-item SCT scale showed adequate convergent validity, discriminant validity, and internal consistency.
