Identifying Priorities for Enhancing Village Health Volunteer's Mental Health Recovery Practices in Thai Rural Communities: A Nominal Group Technique Study

Six patient and public involvement (PPI) advisors participated in the study, comprising two VHVs, one mental health nurse, one caregiver and one peer support worker, to ensure research relevance and applicability. The PPI reviewed the Thai NGT questions to assess the appropriateness of language, particularly in relation to mental health and stigma, leading to minor modifications in wording. Additionally, two VHVs and one caregiver assisted in piloting the questions to evaluate their validity and appropriateness and offered feedback on the procedure, content and timing. They recommended using probing questions to elicit more detailed responses and ensuring concise content to maintain participant engagement.
