The literature indicates that individuals with diabetes do not easily adopt smoking cessation interventions. Given that the success of such interventions depends on patient involvement and attitudes, assessing intervention acceptability, including patient satisfaction and perceived usefulness, is crucial before implementing a smoking cessation intervention. This paper reports the preliminary validation of the satisfaction and perceived usefulness questionnaires for evaluating smoking cessation interventions among individuals with diabetes.
Validity study.
The satisfaction questionnaire contained eight statements while the perceived usefulness questionnaire had fourteen; both rated on a 5-point Likert scale. Content validation involved five tobacco cessation facilitators rating item relevance using a 4-point ordinal rating scale, suggesting improvements. The questionnaires were also translated into Maltese for local use and assessed for translation validity using a similar scale. Unanimous agreement among experts was required for item relevance and equivalence. Thirty-four individuals with type 1 or type 2 diabetes, attending a diabetes-specific smoking cessation intervention, received either the Maltese or English versions of the questionnaires. Internal consistency was measured using Cronbach's alpha.
After two rounds of content validation, the experts unanimously agreed on item relevance and conceptual equivalence. Fifteen and sixteen participants completed the Maltese and English versions of the questionnaires, respectively. Both questionnaires' versions were found to have a high internal consistency (>0.8).
These findings provide the initial validation of these instruments for assessing the acceptability of smoking cessation interventions among individuals with diabetes. Further validation in different settings using a larger sample is suggested.
文献表明，糖尿病患者不容易采用戒烟干预措施。鉴于此类干预措施的成功取决于患者的参与度和态度，在实施戒烟干预之前，评估干预措施的可接受性，包括患者满意度和感知有用性，至关重要。本文报告了用于评估糖尿病患者戒烟干预措施的满意度和感知有用性问卷的初步验证情况。
效度研究。
满意度问卷包含8项陈述，感知有用性问卷有14项；均采用5点李克特量表评分。内容效度涉及5名戒烟促进者使用4点有序评分量表对项目相关性进行评分，并提出改进建议。问卷还被翻译成马耳他语以供当地使用，并使用类似量表评估翻译效度。项目相关性和等效性要求专家们达成一致意见。34名1型或2型糖尿病患者参加了特定于糖尿病的戒烟干预，他们分别收到了马耳他语或英语版本的问卷。使用克朗巴哈系数测量内部一致性。
经过两轮内容效度验证，专家们就项目相关性和概念等效性达成了一致意见。分别有15名和16名参与者完成了问卷的马耳他语和英语版本。发现两个问卷版本都具有较高的内部一致性（>0.8）。
这些发现为这些工具在评估糖尿病患者戒烟干预措施可接受性方面提供了初步验证。建议在不同环境中使用更大样本进行进一步验证。
