Predictors of dropout in cognitive behavior and interpersonal online brief psychotherapies for essential professionals during the COVID-19 pandemic

Premature dropout from psychotherapy can harm patients and increase mental health costs. This study identified predictors of dropout in brief online psychotherapy for essential workers during the COVID-19 pandemic. This was a secondary analysis of a randomized trial on 4-week CBT or IPT protocols. Participants provided sociodemographic data and completed the Patient-Reported Outcomes Measurement Information System and Burnout Assessment Tool Short-Form. Predictors were analyzed in three blocks: sociodemographic, clinical, and therapist characteristics using bivariable and multivariable analyses. The sample included 804 individuals who attended at least the first session of either CBT ( n = 403) or IPT ( n = 401). A total of 17.2% ( n = 138) of the participants dropped out during the protocol. Significant predictors of dropout included having children (IRR = 1.48; 95% CI: 1.07–2.05; p = 0.016), residing in specific regions of Brazil (Northeast IRR = 1.44; 95% CI:1.04–2.00; p = 0.02 and Midwest IRR = 1.73; 95%CI: 1.13–2.64; p = 0.01), therapist male sex (IRR = 2.04; 95% CI: 1.47–2.83; p =
