Description
本研究の目的は,助産師の職場ストレッサーを測定する尺度を作成し,バーンアウトとの関連要因を検討することである.全国の病院161施設に勤務する助産師839人を対象とし,郵送法による自記式質問紙調査を実施した.作成した助産師の職場ストレッサー項目の因子分析,バーンアウトへの要因の重回帰分析を行った.有効回答は708人(有効回答率84.4%)であり,平均年齢は35.3歳であった.助産師の職場ストレッサー尺度8因子55項目を作成した.その下位8因子はそれぞれ,第1因子「医師との非協働的関係」,第2因子「自己の助産力への低評価」,第3因子「助産師スタッフ間の支援不足」,第4因子「対象者との関係の困難さ」,第5因子「仕事の量的負荷」,第6因子「助産関連以外の業務要求への負担」,第7因子「提供するケアへの不全感」と第8因子「評価制度の不備」であった.助産師の職場ストレッサー下位尺度への関連要因は,年齢,月平均給与,職位,現職場勤続年数,通算分娩経験数,月平均夜勤回数,病棟助産師数,産科病床数であった.バーンアウトの関連要因は,年齢,月平均夜勤回数,助産師スタッフ間の支援不足,対象者との関係の困難さ,仕事の量的負荷であった.本研究では,助産師の職場ストレッサー尺度の信頼性と妥当性が確認できた.助産師の職務上の職場ストレッサーであるスタッフ間の葛藤及び仕事の負荷は,助産師のバーンアウトを導く可能性があることが示唆された.病院勤務助産師のバーンアウト予防において,職務上の葛藤や労働負荷の程度を把握し,それを低減するための対策と支援が必要である.
This study aimed to develop a scale to measure work-related stressors among Japanese midwives working in hospitals and to determine potential demographic and job-related factors that may be associated with burnout. A mailed self-administered questionnaire survey targeted 839 midwives working at 161 hospitals across Japan. In order to determine the relationship between the Maslach Burnout Inventory(MBI)subscales and work-related stressors, factor analysis and multiple regression analysis were carried out. Valid responses were obtained from 708 participants(valid response rate:84.4%)with a mean age of 35.2 years. A Midwife Work-Related Stress Scale consisting of 55 items in the following 8 categories was created:"poor collaboration between midwives and obstetricians"(factor 1);"low self-evaluation of own midwifery practice"(factor 2);"poor co-worker(midwives)support"(factor 3);"difficult relationships with pregnant women or their families(factor 4);"excessive workload"(factor 5);"demand of duties besides midwifery job"(factor 6);"unsatisfactory performance of care"(factor 7);and "inadequate management system"(factor 8).Variables associated with subcategories of the Midwife Work-Related Stress Scale comprised "age", "salary", "work position", "years of midwifery experience", "night work", "number of midwives", and "obstetrics bed capacity". Variables associated with the MBI were "age", "night shift", "poor co-worker(midwives)support", "difficult relationships with pregnant women or their families", and "excessive workload". The present study confirmed the reliability and validity of the Midwife Work-Related Stress Scale. These findings suggest that an effective strategy for preventing burnout in midwives is to develop educational and supportive systems, reduce the quantitative work burden, and obtain supportive feelings from colleagues and supervisors.
