本研究之目的在探討機構正式照顧者之約束知識、態度與使用約束理由的關係。抽樣方法採方便取樣，樣本來自北市16所養護機構及高雄市2所護理之家之護理師、護士及護佐總計68名。研究結果顯示：約束知識的得分為護理師最高，護佐最低，正式照顧者的職別、年齡、有無專業證書、醫護相關工作年資及是否接受約束訊息與約束知識的得分有統計上的顯著差異（ps<.05）。在約束態度的得分為護理師與護士皆高於護佐，正式照顧者有無專業證書、醫護相關工作年齡與約束態度的得分有統計上的顯著差異（ps<.05）。除護士較護佐不贊同使用約束理由外，其餘特性無統計上顯著意義。正式照顧者基本特性與約束知識、態度與使用約束理由之相關，顯示正式照顧者的約束知識與年齡之相關為r=-.24、與工作年資為r=.29、與約束態度為r=.31，皆達統計之顯著水準（ps<.05）。約束態度與工作年資之相關為r=.24，亦達統計之顯著水準（p<.05）。然而約束知識、態度和使用約束理由之間，則無顯著相關。上述結果顯示正式照顧者的年齡越大、工作年資越少、其約束知識越差；工作年資越久、約束知識越佳、越不喜歡約束；而約束知識、態度和使用約束理由沒有相關存在。依據研究發現，建議應加強正式照顧者在約束知識的了解，修正其對約束的態度，發展約束替代方案以減少住民受約束的機會。

　　　　　The purpose of this study was to investigate the relationship between knowledge of restraint and attitude toward restraint and reasons for restraint usage observed in formal caregivers in institutions. A total of 68 caregivers comprising registered professional nurses, registered nurses and nursing assistants were chosen from 16 intermediate care facilities in Taipei and 2 nursing homes in Kaohsiung. The research findings showed that registered professional nurses had higher scores in knowledge of restraint usage than nursing assistants. There were significant differences in knowledge of restraint found according to formal caregivers' job positions, age, licensure status, seniority, and restraint information obtained from various resources (ps<.05). In attitude towards restraint, the registered professional nurses and registered nurses had higher scores than nursing assistants. There were significant differences in attitude towards restraint according to different formal caregivers' licensure status and seniority (ps<.05). Analysis of the reasons for restraint usage revealed that nurses were less in favor of the reasons to use restraints than nursing assistants. There were significant correlations between formal caregivers' knowledge of restraint and age (r=-0.24), seniority (r=0.29) and attitude toward restraint (r=0.31). Attitude toward restraint had a significant positive relationship with seniority (r=0.24). However, there were no significant relationships between knowledge of restraint and attitude toware restraint and reasons for restraint use. The above results expressed that the older and lower seniority level formal caregivers had lower scores of knowledge about restraint. The higher the seniority and the more knowledge about restraint formal caregivers had, the more unfavorable attitude toward restraint they had. No relationships existed between knowledge of restraint and attitude toward restraint and reasons for restraint use. Recommendations for further study are to improve formal caregivers' knowledge of restraint so as to change their attitude toward restraint in clinical settings, and to develop alternative methodologies geared toward reducing the frequency of restraint.
