Purpose: The study’s aim was to describe the experience of motivational interviewing (MI) training for parents with adolescents. Methods: Focus group interviews were carried out with 12 mothers in 3 groups who participated in the MI training. The study had a qualitative descriptive design, and qualitative content analysis was used. Results: Data analysis was separated into 4 domains: acceptance, relational skills, self-reflection, and rebuilding relationships. Seven categories and 11 subcategories included (1) enhancing acceptance and empathy, (2) recognizing the importance of the MI spirit and applying core skills, (3) improving self-expression and self-control of negative emotions and behavior, (4) recognizing self-problems, and (5) true communication and recovery of trust. Conclusion: Through MI training, participants have experienced not only the enhancement of their communication skills but also personal modifications (in self-acceptance, self-reflection, and self-control) and positive interpersonal relationships (rebuilding relationships). In addition, participants have realized the importance of listening and reflection in such experiences. Reflection training has provided participants meaningful experiences. Our key insight from these findings is that skill is not most important in communication training. MI elements such as acceptance, collaboration, and a respectful attitude are more likely to be used than conventional communication skills.
