Objective:

To evaluate the usability and technical functionality of Kalmer, a mobile app designed to assist young individuals engaging in non-suicidal self-injury (NSSI) by integrating Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT) strategies.

Key Findings:
  • High usability scores (SUS mean: 81), indicating strong user satisfaction and functionality.
  • Users rated objective quality as good (mean = 3.88/5) and subjective quality as improvable (mean = 2.99/5).
  • Perceived the app as useful (mean = 3.66/5).
Interpretation:

Kalmer has the potential to enhance self-awareness, knowledge, and help-seeking attitudes among users through its integrated therapeutic features.

Limitations:
  • Sample size was small (26 participants).
  • Participants were non-clinical, which may not reflect the experiences of those in clinical settings, potentially limiting generalizability.
  • User engagement and content personalization need improvement.
Conclusion:

Kalmer shows feasibility as a complementary tool in NSSI treatment and sets the stage for future clinical trials.
