一般病棟で勤務するフルタイム勤務看護師の短時間勤務看護師との協働意識尺度の開発

Development of Collaboration Consciousness Scale for Full-Time Nurses in Working with Part-Time Nurses in General Wards

要旨

目的：短時間勤務看護師との協働意識尺度を開発することである．

方法：多様な雇用・勤務形態及び働きやすい職場作りに着手している病院について，病床数と設置主体を指標に機縁法とホームページ検索により選出した東海・近畿地方8病院の一般病棟で，短時間勤務看護師と協働しているフルタイム勤務看護師を対象とした．項目分析，確認的因子分析を用いた構成概念妥当性の検討により尺度を構築し，信頼性，基準関連妥当性を検討した．

結果：全48項目に回答した390人を対象とし分析した結果，〈差異化意識〉〈おかげ様意識〉〈しわ寄せ意識〉〈お互い様意識〉の4因子26項目構造となり，許容できるモデル適合度が示された．本尺度と松本ら（1999）による職務満足尺度，「協働に対する同意性」との間に関連をみとめ，基準関連妥当性を確認した．Cronbachのα係数（0.678〜0.915）により，概ね内的整合性も確認できた．

Purpose: The present study aimed to develop a scale measuring full-time nurses' collaboration consciousness with part-time nurses (CCSFN-PN).

Method: The participants consisted of full-time nurses in working with part-time nurses. Scale development involved several phases, including item development, reliability testing, criterion-related validity testing, and construct validity testing.

Result: Data from 390 nurses who responded to all 48 items of the CCSFN-PN were analyzed (response rate: 50.5%, valid response rate: 87.8%). Exploratory factor analysis revealed four factors with 26 items. They were “differentiation, sense of appreciation, sense of covering-up the mess, and sense of mutual help”. The model showed approximately good fit to the data by confirmatory factor analysis (GFI = 0.846, AGFI = 0.816, RMSEA = 0.074) A significant correlation was observed between the CCSFN-PN and Job Satisfaction Scale (r_s = 0.314) as well as “Agreement to Collaborate with Part-time Nurses” (r_s = 0.365), thus confirming construct validity and criterion-related validity. Cronbach's α coefficient was 0.895 for the overall scale and 0.678-0.915 for subscales, confirming general internal consistency.

Conclusion: The results prove the reliability and validity of the CCSFN-PN. The CCSFN-PN can be used to assess full-time nurses' collaboration consciousness with part-time nurses.
