Non-attendance in randomized remote mental health clinical trial during the COVID-19 pandemic.

During the COVID-19 pandemic, a significant increase in psychiatric symptoms was found among essential service professionals (professionals or interns from the health and educational sector) who were exposed to high-risk contamination areas. These symptoms impair functionality, impacting quality of life, work, autonomy, and relationships. Recent data show that brief interventions are effective; however, between 20 and 30% of those individuals often do not attend their scheduled appointments. This study aimed to identify variables related to non-attendance for remote telepsychotherapy among participants with COVID-19-related emotional distress compared to those who initiated treatment. We included 2097 essential service professionals with PROMIS (Patient-Reported Outcomes Measurement Information System) T-scores ≥70 for anxiety, depression, or irritability who scheduled a remote mental health appointment. Participants completed clinical and sociodemographic data, mental health risk and protective factors, and PROMIS subscales. We conducted a binary logistic regression, using attendance vs. non-attendance as the dependent variable and these demographic and clinical characteristics as independent variables. Of the 2097 participants, 230 (11%) did not attend the first session despite three rescheduling attempts. Non-attendance was associated with the presence of irritability and seeking treatment during the second COVID-19 wave. In contrast, anxious symptoms, older age, and coping mechanisms that typically include intellectual and reading activities were associated with attendance. Our findings shed light on non-attendance patterns in mental health services, revealing that personal characteristics and environmental factors significantly contribute to missed appointments. Understanding these dynamics can improve patient engagement and adherence to mental health treatments, particularly in the context of telepsychotherapy during the COVID-19 pandemic.
