Introduction
The rise of mental health problems in youth highlights the need for accessible and cost-effective psychological interventions. Blended interventions, which combine face-to-face and online sessions, can be an adequate response to the increase in demands for youth mental health services. Although this can be a promising approach, effective dissemination depends on the professionals´ acceptance.

Objectives
This study aimed to explore the acceptability of and intention to use blended interventions by psychologists working with children with emotional disorders and to examine their predictors, including previous knowledge, expectancies (i.e., performance expectancy, effort expectancy, social influence, and facilitating conditions), and attitudes toward evidence-based practices.

Methods
The sample consisted of 76 Portuguese psychologists (Mage = 37.26 years, SD = 10.47; 92.1% female) working in youth mental health services. The participants completed an online protocol to evaluate the different dimensions included in the study.

Results
The results showed that most participants demonstrated moderate to high acceptability of blended psychological interventions for emotional disorders in youth and intend to use them in the future. Regression analysis showed that performance expectancy and positive attitudes toward evidence-based practices were significant predictors of acceptance of blended interventions and that social influence was a significant predictor of both acceptance of and intention to use blended interventions.

Conclusion
These results emphasize the importance of sharing the findings of blended interventions, changing professionals’ attitudes toward evidencebased practices, and collaborating more closely with organizations and institutions to advance standards that encourage the adoption of this intervention format.
