[Development of a Counseling Guide for Rehabilitation Specialist Counseling in the German Pension Insurance System on the Requirements of the Federal Participation Act: A Delphi Study].

The aim of this study was to develop a concept for implementing the requirements of the Federal Participation Act (Bundesteilhabegesetz, BTHG) in rehabilitation counseling through the use of a Delphi study.We employed a modified Delphi technique, involving twelve rehabilitation counselors and seven managerial experts in the field of vocational rehabilitation services. Based on a legal analysis, three focus groups were formed to explore potential implementation strategies and best practice examples for meeting the statutory requirements of the BTHG. Subsequently, two rounds of written Delphi surveys were conducted to reach consensus on a counseling concept in line with the BTHG.After two Delphi rounds, structured feedback was statistically evaluated, resulting in 58 recommendations. The recommendations address issues such as determining the right of choice and preference, assessing individual life realities during counseling sessions, providing information and support in workplace integration management, implementing coordinated service provision in counseling, and networking efforts, as well as general counseling topics.The results outline the requirements that the BTHG imposes on rehabilitation counseling and provide a solid foundation for advisory practices.
