紙筆版結核IAT（Implicit Association Test：潜在連合テスト）の作成および信頼性・妥当性の検討

Development of a Paper Version of the Tuberculosis Implicit Association Test (IAT) and Verifying its Reliability and Validity

要旨

　目的：結核に対する潜在的意識を測定する紙筆版結核Implicit Association Test（IAT）を開発する．

　方法：看護学生96名と一般学生27名を対象に，信頼性，妥当性を検討した．

　結果：看護学生41名と一般学生20名から有効回答を得た．再テスト信頼性における級内相関係数は0.679であった．弁別的妥当性ではIAT値と社会的望ましさ尺度に有意な相関を認めなかった（r = 0.023, p = 0.861）．既知集団妥当性では，看護学生と一般学生，感染看護学単位取得の有無の比較でIAT値に有意差を認めず（p = 0.357, p = 0.827），結核の知識とも相関を認めなかった（r = 0.032, p = 0.845）．併存妥当性では，感染脆弱意識とIAT値に相関を認めなかった（r = 0.190, p = 0.142）．

　結論：紙筆版結核IATは一定の信頼性・妥当性を有するが，既知集団妥当性はさらなる検討を要する．

　Objectives: This study aimed to develop a paper version of the Tuberculosis Implicit Association Test (IAT) and verify its reliability and validity.

　Methods: To evaluate explicit awareness of infections, 96 nursing and 27 psychology students were asked to complete a survey that included a paper version of the Tuberculosis IAT and other existing psychometric scales. Test - retest reliability and discriminant, known-groups, and concurrent validities of the Tuberculosis IAT were then assessed.

　Results: 41 nursing students and 20 psychology students completed the questionnaire (valid response rate: 42.7% and 74.1%, respectively). The test - retest reliability was confirmed by the intraclass correlation coefficient of 0.679. Regarding discriminant validity, as hypothesized, the IAT scores did not correlate with the social desirability scale score (r = 0.023, p = 0.861). Contrary to our hypothesis concerning known-groups validity, there was no significant difference in IAT scores between nursing and psychology students (t = 0.929, p = 0.357) or among nursing students seeking credit for the course on infectious disease nursing (t = - 0.220, p = 0.827). In contrast, as hypothesized, there was no significant correlation between nursing students' knowledge of tuberculosis and the IAT scores (r = 0.032, p = 0.845). Additionally, regarding concurrent validity, no significant correlation was found between the perceived vulnerability to disease scale and IAT scores (r = 0.190, p = 0.142), contrary to the hypothesis.

　Conclusions: Although the paper version of the Tuberculosis IAT was considered to have a sufficient reliability and validity, further investigation into its known-groups validity was deemed necessary.
