Validate an instrument to measure the Perceived Social Support in outpatients who are in treatment to hypertension and/or diabetes mellitus ii.
Observational and exploratory design with mixed methods, qualitative and quantitative.
Two community health centers from the municipality of Puente Alto (Santiago, Chile).
Hypertensive and/or diabetic patients between 18 and 65 years old. A purposive sample was undertaken for the qualitative study, and a random sample for the final survey.
Focus groups and semi-structured interviews were conducted to explore the constructs of social support as perceived by patients. According to expert opinion and literature review, a scale of social support was selected and a pilot study was conducted in 40 patients, then we interviewed in depth to some of those participants. The instrument was modified according the results of this process. The final version was applied to 250 participants.
The construct existence was verified in the population. In the adaptation, one item was eliminated. The alpha of Cronbach was 0.89 and the factorial analysis had the same four factors from the original study. Nine new items obtained from the focal groups were added to the instrument, obtaining an alpha of Cronbach of 0.92.
The final instrument has good psychometric proprieties, and is applicable in our population. The additional items from the qualitative study improve its internal consistency, but don't add new information about Perceived Social Support. This is consistent with other studies, and suggests the application of the original version of the instrument.
验证一种用于测量高血压和/或2型糖尿病门诊患者感知社会支持的工具。
采用定性和定量相结合的观察性与探索性设计。
来自智利圣地亚哥蓬塔阿尔托市的两个社区卫生中心。
年龄在18至65岁之间的高血压和/或糖尿病患者。定性研究采用立意抽样，最终调查采用随机抽样。
进行焦点小组和半结构化访谈，以探索患者所感知的社会支持结构。根据专家意见和文献综述，选择了一种社会支持量表，并在40名患者中进行了预试验，然后对其中一些参与者进行了深入访谈。根据这一过程的结果对该工具进行了修改。最终版本应用于250名参与者。
在总体中验证了该结构的存在。在改编过程中，删除了一个项目。克朗巴赫α系数为0.89，因子分析与原研究具有相同的四个因子。从焦点小组获得的九个新项目被添加到该工具中，克朗巴赫α系数为0.92。
最终工具具有良好的心理测量学特性，适用于我们的人群。定性研究中的附加项目提高了其内部一致性，但没有增加关于感知社会支持的新信息。这与其他研究一致，并建议应用该工具的原始版本。
