ObjectivesThe study aimed to explore psychotherapists' attitudes towards new technologies. Understanding the factors influencing their acceptance of technologies is essential to improving the accessibility, quality, and effectiveness of psychotherapeutic care in the digital age. Based on previous research from different fields (e.g., e‐government and mobile applications), we integrated the Unified Theory of Acceptance and Use of Technology (UTAUT‐T) with the Technology Readiness Index (TRI). UTAUT‐T focuses on one's perception of technology, while TRI emphasizes individual characteristics. Therefore, we regard psychotherapists' attitudes towards digital solutions by analysing factors related to technology and users (psychotherapists).MethodsWe conducted an online questionnaire study involving 391 psychotherapists aged 25–66 (M = 40.90; SD = 7.79). Participants completed self‐report questionnaires: UTAUT‐T, TRI 2.0, and a survey measuring technology usage at work.ResultsThe model explained 30.2% of the variance in actual technology usage and 57.6% in behavioural intention. Both technology‐related and therapist‐related factors affect technology use. Some factors directly influence use behaviour (optimism, ease of use, convenience), while others are mediated by behavioural intention (pressure from others, professional support, therapy quality expectations).ConclusionsTechnology‐related and therapist‐related factors influence psychotherapists' use of technology. The study revealed that optimism plays a crucial role in addition to behavioural intention. This insight is vital for implementing new technologies in mental health services.
