Satisfaction of Patients with Diabetes Mellitus and Caregivers with an Abdominal Manikin for Insulin Injection Training: A Prototype Testing

Abstract

Objective: This descriptive research aimed to test the prototype of an abdominal manikin for insulin injection training. The objective was to study the level of satisfaction with the use of an abdominal manikin for insulin injection training among patients with diabetes mellitus and caregivers. Methods: A purposive sampling method was used to select 32 participants, consisting of diabetic patients or their caregivers who were administering insulin injections. Data were collected between August 2023 and July 2024. The instruments included: 1) a demographic questionnaire, and 2) a satisfaction evaluation form on using an abdominal manikin for insulin injection training, covering usability and design aspects, which was verified by three experts, yielding a content validity index (CVI) of 1. The reliability was confirmed with a Cronbach’s alpha coefficient of .88. Data were analyzed using descriptive statistics. Results: The findings revealed that the overall satisfaction of the participants with using an abdominal manikin for insulin injection training was at the highest level (M = 4.38, SD = .46). When considering specific aspects, the top three aspects of satisfaction in terms of usage were: safety in use (M = 4.66, SD = .55), durability (M = 4.53, SD = .62), and ease of use without complexity (M = 4.50, SD = .67). The top three aspects of satisfaction in terms of design were: creativity in designing the insulin injection training model for type 2 diabetes mellitus (M = 4.53, SD = .62), neatness and aesthetics of the Insulin Injection training model (M = 4.38, SD = .66), and appropriateness of shape and size (M = 4.28, SD = .68). Conclusion: The development of the simulated abdomen for insulin injection training provides realistic characteristics similar to human skin, offering convenience, safety, and durability, effectively substituting more expensive models.
