Customization options in consumer health information materials on type-2 diabetes mellitus-an analysis of modifiable features in different types of media.

Introduction: The understanding of health-related information is essential for making informed decisions. However, providing health information in an understandable format for everyone is challenging due to differences in consumers' health status, disease knowledge, skills, and preferences. Tailoring health information to individual needs can improve comprehension and increase health literacy. Objective: The aim of our research was to analyze the extent to which consumers can customize consumer health information materials (CHIMs) for type-2 diabetes mellitus through various media types. Methods: We conducted a comprehensive search for various CHIMs across various media types, such as websites, apps, videos, and printed or printable forms. A representative sample of CHIMs was obtained for analysis through blocked randomization across the various media types. We conducted a quantitative content analysis to determine the frequency of user-centered customization options. Cross-comparisons were made to identify trends and variations in modifiable features among the media. Results: In our representative sample of 114 CHIMs, we identified a total of 24 modifiable features, which we grouped into five main categories: (i) language, (ii) text, (iii) audiovisual, (iv) presentation, and (v) medical content. Videos offered the most customization opportunities (95%), while 47% of websites and 26% of apps did not allow users to tailor health information. None of the printed or printable materials provided the option to customize the information. Overall, 65% of analyzed CHIMs did not allow users to tailor health information according to their needs. Conclusion: Our results show that CHIMs for type-2 diabetes mellitus could be significantly improved by providing more customization options for users. Further research is needed to investigate the effectiveness and usability of these options to enhance the development and appropriate provision of modifiable features in health information.

Defining a competency map for a practical skill.

BACKGROUND: In recent years there has been a move towards a competency-based model for assessing the performance of practical procedures in clinical medicine rather than the traditional assumption that competency is achieved with increasing experience. For such an assessment to be valid, the necessary competencies comprising that skill must be identified. Our aim was to map the individual competencies necessary to perform a given procedural skill using spinal anaesthesia as the example, and to explore the relationship of individual competencies with each other. METHODS: In the first part of the study an extensive hierarchical task analysis (HTA) was undertaken to determine the competencies necessary for the performance of spinal anaesthesia. Secondly, the concept of competency-based knowledge space theory (CbKST) was applied to the map. CbKST is based on the principle that acquisition of a specific skill is usually preceded by a number of dependent or prerequisite skills. Our aim was to map the individual competencies necessary to perform a given procedural skill RESULTS: The analysis yielded a comprehensive HTA of the skills necessary to perform spinal anaesthesia, comprising 509 individual competencies. Applying the concept of CbKST yielded 194 key competences with at least one dependent or prerequisite skill. DISCUSSION: We have defined a comprehensive HTA or competency map for use in the assessment of the performance of spinal anaesthesia. This CbKST approach will provide clinicians who undertake medical procedures to better understand their own performance, and to improve over time.

Comparative judgments with missing information: a regression and process tracing analysis.

We had participants decide which one of two applicants was better qualified for a scholarship. They also judged the difference between them (comparative judgment). The applicants were described by features (grades) in different subjects (dimensions). The grades on some dimensions were missing (unique dimensions) for an alternative while all the grades were available on other dimensions (common dimensions). In a conventional regression analysis, we found that decision makers gave more weight to dimensions when they were common than when they were unique. However, this commensurability effect was limited to medium important dimensions and did not apply to dimensions of high or low importance. We also observed how participants retrieved information for the choice alternatives and analysed how importance and commensurability are reflected in the processing prior to the decision. Features on more important or common dimensions were inspected earlier than features on less important or unique dimensions. Participants preferred dimensional transitions and inspected features on unique dimensions longer than their common counterparts. This finding suggested that participants used inferences when features were missing. We propose an outline of a decision heuristic to describe decision making with missing information.

Speed of comprehension of visualized ordered sets.

The authors investigated the effects of visual properties of hierarchical graphs on speed of comprehension: planarity (crossing of lines), slopes (orientation of lines), and levels (adjustment of dots). In each of 4 experiments, 30 participants responded to interpretive questions that required comparisons among the elements of the graph. Knowledge provided to participants differed across Experiments 1a, 1b, and 1c; question demands varied in Experiment 2. Analysis of response latencies showed that crossing of lines is the most influential variable independent of orientation, dot adjustment, and question demands. Speed of comprehension decreased with increasing question demands. When question demands were high, orientation of lines also had an effect on speed of comprehension. Preliminary conclusions for the presentation of hierarchical graphs are drawn.
