Measuring the profiles of the security needs of forensic psychiatric inpatients: Validation of the See, Think, Act Scale

Introduction: This study aimed to develop and validate a Chinese version of the See, Think, Act Scale (C-STA). The relational security of the Department of Forensic Psychiatry of Castle Peak Hospital, which provides territory-wide forensic psychiatric services in Hong Kong, was measured.

Methods: The See, Think, Act Scale was first translated into Chinese, then back-translated into English for comparison, and finally, subject to modification until alignment was achieved. Its content validity and face validity were explored through expert panel evaluation and focus group discussion, respectively. Eighty-nine Chinese mental health professionals were recruited from six service units to measure the relational security of the Department of Forensic Psychiatry using the C-STA.

Results: The Cronbach's alpha coefficient for internal consistency was high, with all components exceeding 0.90. The intraclass correlation coefficients for the test-retest reliability of all components ranged from 0.50 to 0.72. Participants had the lowest score on the "patient focus" component (M = 2.56, standard deviation [SD] = 0.32). A significant sex difference in total relational security scores was found (P < 0.001).

Discussion: The C-STA is a valid and reliable instrument to measure the relational security of forensic psychiatric services. "Patient focus" might be the target component of relational security for which the Department of Forensic Psychiatry needs to have interventions. The significant sex difference in total relational security scores needs further exploration.
