The aim was to psychometrically test and evaluate the Swedish functional health literacy scale and the Swedish communicative and critical health literacy scale in patients undergoing bariatric surgery.
A prospective cross-sectional psychometric study.
Patients from three bariatric centres in Sweden were consecutively included in this study.
A total of 704 patients undergoing bariatric surgery filled in the questionnaires preoperatively. Inclusion criteria were scheduled for primary bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy) and greater than 17 years, proficiency in Swedish.
Psychometric outcomes of the Swedish Functional Health Literacy scale and the Swedish Communicative and Critical Health Literacy scale.
There was a higher proportion of females (74.4%, n=523) to males (25.6%, n=180). The mean age was 42 years (SD 11.5). Limited functional health literacy and limited communicative and critical health literacy (including both inadequate and problematic health literacy) was reported in 55% (n=390) and 40% (n=285), respectively. Cronbach alpha for the Swedish Functional Health Literacy scale was α=0.86 and for the Swedish Communicative and Critical Health Literacy scale, α=0.87. Construct validity showed weak to negative correlations between the Swedish Functional Health Literacy scale and income, education and SF-36/RAND36 summary scores. Confirmatory factor analysis showed a one-factor solution for the Swedish Functional Health Literacy scale and a two-factor solution for the Swedish Communicative and Critical Health Literacy scale.
The Swedish Functional Health Literacy scale and the Swedish Communicative and Critical Health Literacy scale are valid and reliable to use for patients undergoing bariatric surgery in a Swedish context. Measuring dimensions of health literacy can be used as a guide for the development of health literacy friendly patient information in patients undergoing bariatric surgery.
本研究旨在对接受减重手术的患者进行瑞典功能性健康素养量表和瑞典交流与批判健康素养量表的心理测量学测试和评估。
前瞻性横断面心理测量学研究。
本研究连续纳入了瑞典三个减重中心的患者。
共 704 名接受减重手术的患者在术前填写了问卷。纳入标准为拟行原发性减重手术（Roux-en-Y 胃旁路术或袖状胃切除术），年龄>17 岁，精通瑞典语。
瑞典功能性健康素养量表和瑞典交流与批判健康素养量表的心理测量学结果。
女性（74.4%，n=523）多于男性（25.6%，n=180）。平均年龄为 42 岁（SD 11.5）。报告有限功能性健康素养和有限交流与批判健康素养（包括不足和有问题的健康素养）的患者分别占 55%（n=390）和 40%（n=285）。瑞典功能性健康素养量表的克朗巴赫 α 值为 0.86，瑞典交流与批判健康素养量表的克朗巴赫 α 值为 0.87。结构效度显示，瑞典功能性健康素养量表与收入、教育和 SF-36/RAND36 综合评分之间呈弱至负相关。验证性因子分析显示，瑞典功能性健康素养量表呈单因子解决方案，瑞典交流与批判健康素养量表呈双因子解决方案。
瑞典功能性健康素养量表和瑞典交流与批判健康素养量表在瑞典背景下对接受减重手术的患者是有效和可靠的。测量健康素养的维度可以作为指导患者在接受减重手术时制定健康素养友好型患者信息的指南。
