Purpose: Suicide attempts have been increasing in Taiwan. Self-injury crisis intervention has become a necessary competency for professional practitioners. We develop a scale for professionals to use during crisis intervention. Methods: The items comprising the scale were developed through a literature review of crisis intervention theories, and input from experts in crisis intervention and scale development. The first draft of the scale included 90 items. We collected online responses from practitioners who had graduated from departments of psychology, counselling, or social work with experience in self-injury crisis intervention in the past 3 years. We first conducted item analysis and exploratory factor analysis with data from 120 participants. Fifty items were retained. In the second stage, we used data from 127 participants to conduct confirmatory factor analysis and model modification. A total of 25 items were retained. We tested reliability and validity. Results: The Cronbach's α of the 7 subscales ranged from .78 to .91. The Cronbach's α of the overall scale was .95. The split-half reliability of the overall scale was .89. The split-half reliability of the 7 subscales ranged from .81 to .90, and the composite reliability of the 7 subscales ranged from .81 to .91. Conclusions: The formal scale (MD-SCIS) consists of 7 subscales: (1) building a relationship, (2) crisis assessment and context inquiry, (3) emotional support, (4) specific action plan, (5) resource linkage and systematic consultation, (6) follow-up and estimation, and (7) self-regulation and professional development. Based on the results, we recommend practical applications and research implications.
