ABSTRACT: Although the detection rate for unruptured intracranial aneurysm (UIA) has improved since the 1990s, the quality of life and psychosocial status of patients living with UIA have been negatively affected. However, a comprehensive assessment tool for UIA patients is still awaited. This study aimed to develop and validate a disease-specific scale to assess UIA patients' psychosocial well-being in their daily lives. On the basis of previous qualitative research, 52 items on a six-dimension scale were generated. After a pilot study, statistical analysis was conducted to examine construct validity-including convergent validity, discriminant and known-group validity, and internal reliability. Between 2010 and 2011, 124 patients across three hospitals in Japan were tested using a tentative scale. As a result of exploratory factor analysis, we identified 25 items based on five conceptually derived dimensions (psychological stability, trust in healthcare resources, satisfaction with the decision-making process, positive perception of self-management, and confidence in UIA knowledge) as a final psychosocial well-being scale for UIA patients (UIA-PW scale). Cronbach's alpha coefficients for each subscale ranged between .76 and .90, with .83 for the total score, which indicated satisfactory internal consistency. The total score for the UIA-PW scale correlated significantly with the existing quality of life and mental health scales, but it is important to note that psychological stability and positive perception of self-management were negatively correlated. Although additional investigation is needed, the UIA-PW scale shows reasonable validity and reliability in assessing psychosocial well-being of patients living with UIA.
