Outcome Measures

Primary Outcomes (1)

• Change From Baseline in Knowledge and Decision-Making Regarding Dental Care, Assessed by a Self-Administered Questionnaire (Percentage of Correct Responses)

  Study outcomes are defined as the effects of the interventions measured using a self-administered questionnaire. Questionnaire responses are summarized as a percentage score ranging from 0% to 100%, with 100% indicating all responses answered correctly. For each research question, outcomes are calculated as the change (Δ) in percentage scores between pre-intervention (baseline) and post-intervention assessments.

  Immediately after completion of the educational intervention (single study visit)

Interventions

Educational material, OTHER

Patients with head and neck cancer and practicing dentists in Germany participate in an anonymous, prospective pre-post survey study. Both groups complete a baseline questionnaire assessing demographic characteristics as well as knowledge, attitudes, experiences, and decision-making related to dental care in the context of head and neck cancer treatment. Following the baseline assessment, participants receive group-specific, guideline-based written educational information. After reviewing the educational material, participants complete a post-intervention questionnaire with identical content. The effect of the educational intervention is evaluated by comparing pre- and post-assessment responses within each group.

Model Details: This is a prospective, survey-based pre-post study conducted in two participant groups: patients with head and neck cancer and practicing dentists. Both groups complete an anonymous online questionnaire assessing knowledge, attitudes, experiences, and practices related to dental care in the context of head and neck cancer. After the baseline assessment, group-specific, guideline-based written educational information is provided. Participants then complete a post-assessment with identical content. The effect of the educational intervention is evaluated by comparing pre- and post-assessment responses within each participant group.
