Effect of an Educational Nail Biopsy Video on Pre-operative Anxiety, Health Literacy, and Patient Satisfaction

Anxiety, as measured by the State Trait Anxiety Inventory

State Trait Anxiety Inventory uses a scale of 1-4 for each question, with 1 being "not at all" and 4 being "very much so." The maximum score is 80, and the minimum score is 20. Scores from 20-37 indicate "no or low anxiety," scores from 38-44 indicate "moderate anxiety," and scores from 45-80 indicate "high anxiety."

Anxiety, as measured by the Amsterdam Preoperative Anxiety and Information Scale

The Amsterdam Preoperative Anxiety and Information Scale uses a Likert scale from 1-5. The questions focus on anxiety and the need for information, creating two separate sub-scores. This measure assesses the anxiety sub-score, which ranges from 4 to 20 (4 questions) A higher anxiety sub-score indicates a higher anxiety level.

Need for information, as measured by the Amsterdam Preoperative Anxiety and Information Scale

The Amsterdam Preoperative Anxiety and Information Scale uses a Likert scale from 1-5. The questions focus on anxiety and the need for information, creating two separate sub-scores. This measure assesses the need for information sub-score, which ranges from 2 to 10 (2 questions). A higher need for information sub-score indicates a higher information requirement.

Health literacy, as measured by 4 domains of The Health Literacy Questionnaire

Using 4 domains of the The Health Literacy Questionnaire, subjects will respond using a scale from "strongly disagree" (equivalent to 1 point on Likert scale) to "strongly agree" (equivalent to 4 points on Likert scale) or from "cannot do or always difficult" (equivalent to 1 point on Likert scale) to "always easy" (equivalent to 5 points on Likert scale). The maximum score is 86, the minimum score is 19. A higher score indicates higher health literacy, while a lower score indicates lower health literacy.

Patient satisfaction, as measured by a patient satisfaction survey

The patient satisfaction survey uses a scale from "not at all" (equivalent to 1 on a Likert scale) to "very much" (equivalent to 4 on a Likert scale), or from "not acceptable" (equivalent to 1 on a Likert scale) to "Acceptable" (equivalent to 3 on a Likert scale). The maximum score is 27, the minimum score is 7, with a higher score indicating higher satisfaction, and a lower score indicating lower satisfaction.
