Reliability and Validity of the Human Caring Scale for Emergency Nursing

要旨

　目的：救急看護師への半構造化面接の結果から作成した救急看護ヒューマンケアリング実践評価スケール（HCSEN）の信頼性・妥当性を検討した．

　方法：内容妥当性，表面妥当性を検討したHCSEN（60項目）と併存妥当性検討のための外的基準（職務満足に関する質問）の調査を，Web調査会社を通して実施した．救急看護師178名（有効回答率86.4％）を分析対象とし，探索的因子分析，Cronbach's α係数の算出，相関分析，t検定を行った．

　結果：探索的因子分析で8因子が抽出され，Cronbach's α係数は全体0.982，各因子0.723〜0.941であった．HCSEN各因子得点と，外的基準総得点の中間位で分割した2群を比較したt検定では，全ての因子で2群間に有意差が認められた（ps < .002）．

　結論：抽出された各因子の下位尺度において内的整合性は確認され，職務満足に関する質問項目との併存的妥当性も確認された．以上より，HCSENは一定の信頼性を得ることができた．

　Purpose: We aimed to examine the reliability and validity of the Human Caring Scale for Emergency Nursing (HCSEN), which was created from the results of semi-structured interviews conducted with emergency department nurses.

　Method: We administered the HCSEN (60 items), which was examined the content validity and surface validity, as well as the external criteria (questions regarding job satisfaction) for coexistence validity examination through a web research company. Responses from 178 emergency department nurses (valid response rate 86.4%) were analyzed, and exploratory factor analysis, Cronbach's α coefficient calculation, correlation analysis, and t-test were performed.

　Results: Eight factors were extracted by exploratory factor analysis. Cronbach's α coefficient was 0.982 overall, and that for each factor ranged from 0.723 to 0.941. A t-test comparing the HCSEN factor scores and the two groups were divided by the middle of the external criteria total score showed a significant difference between the two groups for all factors (ps < .002).

　Conclusion: Internal consistency was confirmed for the subscales of each extracted factor. Moreover, the coexistence validity with the question items related to job satisfaction was also confirmed. Thus, the HCSEN was able to obtain a certain degree of reliability.
