Self-efficacy is a temporary and influenceable characteristic, related to situations and tasks, mediating health-promoting behaviours. This study aimed to evaluate psychometric properties of a Portuguese version of the Fluid Intake Appraisal Inventory, and to describe self-efficacy in relation to limited fluid intake amongst Portuguese haemodialysis patients. Respondents were recruited from three dialysis units, and 113 of 155 eligible patients gave their informed consent. The translated scale was distributed and collected by the head nurses. Interdialytic weight gain was calculated as percentage of dry weight. Satisfactory psychometric properties were estimated in the Portuguese context. The participants' self-efficacy in relation to low fluid intake was asymmetrically distributed; the majority had moderately to high self-efficacy while some patients had very low self-efficacy to limited fluid intake. There was a significant difference in self-efficacy to fluid restrictions; patients with a weight gain of 3.5% or less presented higher self-efficacy scores than did patients exceeding the cutoff point.
自我效能是一种与情境和任务相关的、暂时且可影响的特征，它在促进健康行为中起中介作用。本研究旨在评估葡萄牙语版液体摄入评估量表的心理测量特性，并描述葡萄牙血液透析患者在液体摄入量有限方面的自我效能。研究对象从三个透析单位招募，155名符合条件的患者中有113名给予了知情同意。翻译后的量表由护士长分发和收集。透析间期体重增加以干体重的百分比计算。在葡萄牙语环境下评估了令人满意的心理测量特性。参与者在低液体摄入方面的自我效能分布不对称；大多数人具有中度至高自我效能，而一些患者对有限的液体摄入具有非常低的自我效能。在液体限制的自我效能方面存在显著差异；体重增加3.5%或以下的患者比超过临界值的患者表现出更高的自我效能得分。
