Proposing Scale Items for Evaluating Practical Competence of Public Health Nurses at Child Guidance Centers

要旨

　目的：児童相談所（以下，児相）保健師の実践能力の評価指標となる項目を提案し，尺度開発にならい，信頼性および妥当性を検討することである．

　方法：全国の児相保健師138名中，34名を分析対象に，先行研究等をもとに作成した17項目を用いて，無記名自記式質問紙調査を行った．構成概念妥当性の検討は，確認的因子分析と仮説検定を実施した．信頼性の検討は，I-T相関，Cronbach's α係数を確認した．

　結果：項目間相関が高い1項目を除外し，16項目で作成した「児相の基本職務を遂行する力」「保護者に寄り添い，その特徴や能力に応じた支援を行う力」「地域の関係機関やネットワークと連携する力」の3因子モデルの適合度指標は，RAMSEA = .065，CFI = .988，SRMR = .084で，仮説検定では8項目中5項目が統計的に支持された．項目全体のCronbach's α係数は .930，3因子では .809〜.888，I-T相関は .47〜.85であった．

　結論：本項目は信頼性と妥当性があると判断できた．児相保健師の実践能力を評価する指標として活用可能と考える．

　Objective: To propose scale items that can be used for evaluation of practical competence of public health nurses working at child guidance centers and to examine its reliability and validity.

　Methods: This study involved 34 public health nurses working at child guidance centers who responded to a questionnaire survey asking about 17 items of practical competence of public health nurses working at child guidance centers. The confirmatory factor analysis and hypothesis testing were conducted to examine the construct validity of the items. The reliability of the items were examined using I-T correlation and Cronbach's α index.

　Results: Excluded one item with high correlation between items, we assumed three factors model using 16 items; “Competence to perform basic duties at child guidance center”, “Competence to provide close support to parents according to their characteristics and abilities” and “Competence to collaborate with local related organizations and networks”. The model fit index was RAMSEA = .065, CFI = .988, SRMR = .084. The hypothesis testing statistically supported 5 out of 8 items. Cronbach's α was .930, and I-T correlation was .47-.85.

　Conclusion: The reliability and validity of these items were confirmed. These items can be used for evaluation of practical competence of public health nurses working at child guidance centers.
