看護職の業務遂行における多重課題に関する研究—卓越性，熟慮性，および自己効力感との関連

Research of the Multitasking of Nurses: Relationship between the Nursing Practice Ability, Cognitive Reflectivity, and Self-efficacy

要旨

　目的：多重課題困難感の要因として看護実践能力，認知的熟慮性，自己効力感との関連を探索することを目的とした．

　方法：看護職349名の基本的属性，多重課題困難感，看護実践の卓越性自己評価尺度（NESCP），認知的熟慮性−衝動性尺度，一般性セルフ・エフィカシー尺度（GSES）について，Mann-Whitney U検定と多重ロジスティック回帰分析を行った．

　結果：多重課題困難感を感じない群でNESCP（p < 0.001）や GSES（p < 0.001）の得点が高く，GSESの得点の増加（aOR = 0.864, 95%CI: 0.803〜0.930）や男性であること（aOR = 2.975, 95%CI: 1.333〜6.639）が，多重課題困難感を低下させる要因であった．

　結論：多重課題困難感の要因として自己効力感と性別が関連していた．自己効力感を高めるような教育を行うことで，多重課題困難感を軽減する可能性が示唆された．

　Objective: The aim of this study was to investigate the relationships between nursing practice ability, cognitive reflectivity, and self-efficacy as factors affecting the sense of difficulty in multitasking.

　Method: Using data from 349 nurses, the Mann-Whitney U test and multiple logistic regression were used to analyze fundamental attributes, the sense of difficulty in multitasking, Nursing Excellence Scale in Clinical Practice (NESCP) scores, cognitive reflectivity-impulsivity scale scores, and general self-efficacy scale (GSES) scores.

　Results: In the group that did not experience the sense of difficulty in multitasking, NESCP (p < 0.001) and GSES (p < 0.001) scores were higher than those in the group that experienced the sense of difficulty in multitasking, and increased GSES scores (adjusted odds ratio = 0.864, 95% confidence interval: 0.803-0.930) and being male (adjusted odds ratio = 2.975, 95% confidence interval: 1.333-6.639) were factors that reduced the sense of difficulty in multitasking.

　Conclusion: Self-efficacy and sex were related to multitasking difficulty. This suggests that conducting educational programs to increase self-efficacy could reduce the sense of difficulty in multitasking.
