Development and Preliminary Evaluation of iCanPlan: A Mobile Health Application for Intimate Partner Violence Prevention in Thailand.

Intimate partner violence (IPV) is a significant global public health issue that requires accessible, scalable, and contextually appropriate interventions. Mobile health (mHealth) technologies provide a promising platform to deliver support, information, and safety planning tools for individuals at risk of IPV. This study aimed to develop and pilot-test iCanPlan, a mobile application designed to support IPV prevention in Thailand. The application evaluates IPV risk, identifies indicators of danger, and provides a countrywide list of assistance sources. iCanPlan consists of four main components: (1) an IPV risk assessment tool, (2) a list of support resources, (3) educational materials presented in the form of infographics, and (4) encouraging quotes from well-known public figures. The app features a clean, user-friendly interface with intuitive navigation and color-coded components to enhance usability. In addition, a preliminary study was conducted with 30 experts from multidisciplinary fields, including gender-based violence research, social work, psychology, public health, and non-governmental organizations. Participants used the application for one month and subsequently evaluated it using a structured questionnaire based on heuristic evaluation principles. The questionnaire assessed usability, safety features, content quality, cultural appropriateness, language clarity, ethical considerations, and overall evaluation using a five-point Likert scale. Data was analyzed using descriptive statistics (mean and standard deviation) in SPSS. The findings demonstrated excellent performance across all domains, with high mean scores for usability (M = 4.93), safety features (M = 4.73), and content quality (M = 4.82), while cultural appropriateness, language clarity, ethical considerations, and overall evaluation achieved perfect scores (M = 5.00). These results indicate strong agreement among experts regarding the application's usability, safety, and relevance. The study highlights the potential of iCanPlan as a culturally appropriate and user-friendly digital intervention for IPV prevention. Further research involving the target population is needed to evaluate its effectiveness and long-term impact on help-seeking behavior and IPV-related outcomes.
