がん患者による看護ケアの質評価質問紙Oncology Patients' Perceptions of the Quality of Nursing Care Scale Short Form（OPPQNCS-SF）の日本語版開発（第1報）—がん専門病院に入院する消化器がん患者を対象として

Development of the Japanese Version of Oncology Patients' Perceptions of the Quality of Nursing Care Scale Short Form (OPPQNCS-SF) (First Report): Perspective of Patients with Gastrointestinal Cancer Who are Hospitalized at Cancer Centers.

要　旨

　目的：がん患者の視点で看護ケアの質を評価する質問紙Oncology Patients' Perceptions of the Quality of Nursing Care Scale Short Form（以下，OPPQNCS-SF）の日本語版を開発する．

　方法：2名の翻訳者（内1名は医療職）が，原版OPPQNCS-SFを日本語に翻訳した．日本語訳したものをプレテストとして身の回りのがん体験者に実施後，関東圏内にあるがん専門病院の消化器外科で入院治療を受ける患者93名に質問紙を配布した．信頼性は一貫性と再現性の観点から，妥当性は内容妥当性・収束妥当性・因子妥当性の観点から検証した．

　結果：89名より質問紙を回収した．Cronbach's α係数は，日本語版OPPQNCS-SF全体で0.94であった．再現性は3項目を除いた14項目で，0.6以上の値をとった．また，日本語版OPPQNCS-SFは，入院患者の満足度を評価するHospital Patient Satisfaction Questionnaire-13（HPSQ-13）の下位尺度コミュニケーションとで0.7以上の高い相関がみられた．日本語版OPPQNCS-SFは，原版と違い1因子構造となった．

　結論：上記よりいくつかの研究の限界はあるが，日本語版OPPQNCS-SFの信頼性・妥当性は証明された．

　PURPOSE: The purpose of this study was to develop a Japanese version of the Oncology Patients' Perceptions of the Quality of Nursing Care Scale Short Form (OPPQNCS-SF) to allow patients with cancer to evaluate the quality of nursing care.

　METHODS: The original English version of the OPPQNCS-SF was translated into Japanese by two translators. After pre-testing on four patients with cancer, the Japanese version of OPPQNCS-SF was administered to 93 inpatients who received hospital care in the Gastrointestinal Surgery Unit, Oncology Center. The reliability and validity of the questionnaire was assessed using Cronbach's alpha test and retesting; convergent validity was measured using the Hospital Patient Satisfaction Questionnaire-13 (HPSQ-13), which evaluates inpatient satisfaction and exploratory factorial analyses.

　RESULTS: A total of 89 inpatients answered the Japanese version of OPPQNCS-SF. Cronbach's αvalue was 0.94 for the Japanese version. The test-retest reliability was ≧ 0.6 in 14 items, except for 3 items. Also, correlation coefficients were ≧ 0.7 between the Japanese version and HPSQ-13. Unlike the original, the Japanese version possessed a one-factor structure.

　CONCLUSIONS: The Japanese version of OPPQNCS-SF is a valid and reliable questionnaire for patients with cancer to evaluate the quality of their nursing care.
