Since the ""Taiwan Disaster Year"" began with the 921 earthquake, Taiwan has witnessed numerous significant disaster events in recent years, resulting in extensive financial losses and loss of life. These events have profoundly affected individuals’ trust and sense of security, leading to a widespread impact on social groups and cultures. As professional healthcare providers, counseling psychologists frequently engage in post-disaster psychological rescue and reconstruction efforts during major disasters or crises. This practice has raised challenges for crisis intervention during such events. Researchers thus aim to understand the landscape and challenges of psychological rescue efforts during domestic disasters. This study uses phenomenological research methods and semi-structured interviews to gather data. It includes interviews with six counseling psychologists, three of whom are certified supervisors who acted as supervisors during disaster events, while the other three provided crisis intervention services as psychologists. The study categorizes its findings into two main themes and eight sub-themes: Experiences of counseling psychologists in post-disaster psychological support: (1) Self-assessment and professional knowledge before providing post-disaster psychological support: This theme explores how psychologists evaluate their readiness and expertise before engaging in disaster relief efforts. (2) Roles and functions of post-disaster psychological support: This examines the specific responsibilities and activities undertaken by psychologists during the support process. (3) Preparatory, initial, mid-term, and long-term actions, including the role of supervisors: This delves into the different stages of psychological support and the crucial role of supervisors in guiding and supporting these efforts. (4) Multiple challenges, physical and mental stress, and cultural and folk challenges after providing post-disaster psychological support: This theme addresses the complex challenges psychologists face following their intervention, including stress and cultural issues. Practical planning to address the challenges of post-disaster psychological support: (1) Implementing drills and psychological education: Emphasizes the importance of preparedness through regular drills and education. (2) Continuous capacity building and case discussions: Highlights the need for ongoing training and discussion of cases to enhance skills and knowledge. (3) Establishing lists and supervisory relationships: Focuses on creating structured relationships and lists to streamline support efforts. (4) Familiarity with cloud and information operations: Stresses the need for proficiency in modern technology to facilitate efficient support. (5) Adjusting expectations and service mentality: Discusses the necessity of adapting expectations and maintaining a service-oriented mindset. Based on the research results, the researcher proposes a systematic approach comprising three steps (""Stop, Look, Ask"") and nine specific suggestions for post-disaster psychological support, serving as a practical reference for crisis intervention practice: ""Stop""—before intervention: (1) Self-assess physical and mental state and willingness to engage: Psychologists need to evaluate their readiness and motivation. (2) Equip with necessary professional knowledge and capacity building: Psychologists need to ensure that they have the required expertise and training. (3) Cultivate the ability for multicultural intervention: Develop skills to effectively engage with diverse cultural backgrounds. ""Look""—during intervention: (1) Understand the roles and functions and fit them appropriately: Matching roles and tasks to individuals’ strengths. (2) Adjust intervention actions at different stages: Modify approaches according to the phase of intervention. (3) Understand challenges and respond positively: Recognize and constructively address difficulties encountered. ""Ask""—after intervention: (1) Physical and mental selfadjustment and return to original balance: Focusing on recovery and well-being. (2) Seek supervisory assistance to reorganize intervention experiences: Utilizing supervision to reflect and improve.(3) Curriculum development and continued education for capacity building: Advocating for ongoing education and training in disaster psychology. Finally, the study concludes with recommendations for future research and suggests areas for further exploration to enhance the effectiveness of psychological support in disaster scenarios.
