シャイネスを測定する潜在連合テストの信頼性・妥当性の検討: 再検査信頼性・基準関連妥当性の観点から

摘要

本研究は，シャイネスを測定する潜在連合テスト（Implicit Association Test；以下IATとする；【1】）の日本語版（相川・藤井【2】）の信頼性と妥当性を，再検査信頼性と基準関連妥当性という2つの観点から検討した．32名の参加者を対象に，2 度にわたって実験を行い，（a）時点lと2における再検査信頼性，（b）時点1におけるシャイネスIAT と自尊心IAT の相関係数から基準関連妥当性をそれぞれ確認した．分析の結果，（a）時点1と2の相関係数はr＝.68(pく01）であり，時点1におけるシャイネスIAT と自尊心IAT の相関係数はr＝－.47(p＜.01）という値が得られた．これらの結果は，シャイネスIAT の再検査信頼性と基準関連妥当性を示すものであり，シャイネスIATが測度として妥当であることが示された．%This paper investigates reliability and validity of Implicit Association Test (in the following, IAT for short) for measuring shyness by seeing test-retest reliability and criterion-related validity. We administered a computerized experiment to 32 participants twice (Time 1 and Time 2) and examined the test-retest reliability over a one-week interval and the criterion-related validity by calculating a correlation coefficient between the shyness IAT score and the self-esteem IAT score. The analyses revealed that the correlation coefficient between the two shyness IAT scores over a one-week interval was computed as r = .68 (p < .01), and the correlation coefficient at Time 1 between the shyness IAT score and the self-esteem IAT score was r = -Al (p < .01). These results endorse the test-retest reliability and the criterion-related validity of shyness IAT, showing that using shyness IAT for measuring implicit shyness is plausible.
