日本語版Attitudes to Suicide Prevention Scale(ASP-J)の妥当性と信頼性―医療従事者の自殺予防に対する態度測定尺度の開発

Validity and Reliability of the Japanese Version of the Attitudes to Suicide Prevention Scale (ASP-J): To evaluate health practitioner's attitudes toward suicide prevention

抄録

　Attitudes to Suicide Prevention Scaleの日本語版(ASP-J)を作成した。原著者の許可を得て，日本語訳を準備し，逆翻訳の手続きにより内容的等価性を確認した。その上で，自殺予防に関する研修の参加者145名を対象にASP-Jを含む質問紙調査を研修の前後で実施した。分析の結果，ASP-Jはプレテスト，ポストテストとも十分な内的一貫性を示した。また研修の前後で自殺予防に対する否定的態度が改善されたことが確認された。さらにASP-Jと，自殺予防への自信尺度および自殺の危機介入スキル尺度(SIRI-JS)の下位尺度「変更」との間に相関関係が認められた。加えて自殺念慮者や自死遺族への対応件数が多いほど，自殺予防に対してより肯定的な態度を有することが確認された。

　This study aimed to develop a Japanese version of the Attitudes to Suicide Prevention Scale (ASP-J) and investigate its psychometric properties. We enrolled 145 health professionals who attended our training programs for suicide prevention to assess the ASP-J and found that it had good internal consistency. In addition, negative attitudes toward suicide prevention were improved through training. The ASP-J scores were associated with the “alteration” factor of the short version of the Suicide Intervention Responce Inventory (SIRI-JS) and the score of confidence in suicide prevention. Furthermore, the experiences of providing counseling to and consulting suicide attempters and survivors were related to better attitudes. In conclusion, the ASP-J has validity and reliability, but further research is needed to explore other related variables and improve the psychometric properties.
