Redevelopment of mental health first aid guidelines for substance use problems: a Delphi study

Background Substance use problems have a major impact on the physical and mental health of individuals, families and communities. Early intervention may have a positive effect on recovery and treatment outcomes for those with substance use problems, reducing related risk and harm. Separate mental health first aid guidelines on how a member of the public could assist someone experiencing or developing alcohol use and drug use problems in high income Western countries were developed using Delphi expert consensus in 2009 and 2011, respectively. This study aimed to synthesise and update these two original guidelines to reflect current evidence and best practice. Methods The Delphi expert consensus method was used to determine the inclusion of statements in the redeveloped guidelines. A questionnaire was developed using previously endorsed helping statements from the original guidelines on alcohol and drug use problems, as well as relevant content identified in systematic searches of academic and grey literature. Three panels of experts (people with lived experience, support people and professionals) rated statements over three consecutive online survey rounds to determine the importance of their inclusion in the guidelines. Statements endorsed by at least 80% of each panel were included. Results 103 panellists completed all three survey rounds. They rated 469 statements and endorsed 300 of these for inclusion in the redeveloped guidelines. Conclusions This study has developed a broader and more comprehensive set of guidelines for how to support a person experiencing or developing a substance use problem. The redeveloped guidelines provide more detail on knowledge about and recognition of substance use problems, approaching and assisting people who want to change or are not ready to change, harm reduction, community-based supports and professional help, but have less on physical first aid actions. Mental Health First Aid International will use these guidelines in future updates of their training courses.
