目的：發展一具美容意願量表，能夠預測醫院員工接受美容的意願，且能揭示一套檢核受試者答題反應的健康信念美容意願報告卡。 方法：利用試題反應理論Rasch模式的WINSTEPS軟體，檢測某醫院員工填答接受美容的意願量表，是否構成單向度的測量。並以迴歸分析找出影響美容意願的因子、以接受者操作特徵曲線找出美容意願量表的決斷點，作為預測美容行動的依據。 結果：12道美容意願量表被檢測出具有兩個特徵因素（自覺罹患分量表及改善必要性分量表）。當兩個分量表合併分數後的決斷點大於2.875分時，對於有意願採取美容行動的準確度達87.1%。檢核受試者答題反應的健康信念美容意願報告卡，標準化殘差可以提供美容服務機構檢視受試者在某題上反應與眾不同的異常揭露。 結論：利用健康信念模式發展出來的美容意願量表，可以用來預測醫院員工之美容意願與行動。

Objectives: To develop a scale that predicts aesthetic intention and ability to take action by hospital employees and incorporates a report card that clearly discloses individual examinees' aberrant responses on items. Methods: A Rasch model based on item response theory (IRT) with WINSTEPS software was utilized to examine an aesthetic intention scale to determine if it formed a single construct. Multiply regress analyses were used to identify the key factors associated with aesthetic intention. Receiver Operating Characteristic (ROC) was applied to determine a cut-off point for examinee's ability to take aesthetic action. Results: The 12-item aesthetic intention scale has two characteristic features (i.e., subscales of perceived susceptibility and essential improvement). The cut-off point was set at 2.875 after combining those two scaled scores and accounted for 87.1% of sensitivity on the target population. The report card of examinee's aberrant responses on items using standardized residual scores can provide aesthetic service institutes with a tool for following up on unusual responses in comparison with the model's expectations. Conclusions: The aesthetic intention scale examined by the Rasch model can be used with hospital employees to predict aesthetic intention and ability to take action.
