<i>Primum non nocere</i> – are adverse events accurately reported in studies on psychological interventions for children?

Adverse Events (AEs) are defined as any unfavorable and unintended sign or symptom, that may occur during or after receipt of any intervention. The principle of non-maleficence requires careful consideration to ensure that existing or new psychological interventions are not harmful before they can be considered beneficial. In this context, the safety of psychological interventions, including the possible occurrence of AEs, is increasingly important for patients, families, and clinicians. The evaluation of AEs is crucial to obtain a complete understanding of the risk/benefit balance of psychological interventions. There is a need for researchers and clinicians to assess and report AEs comprehensively and in a coordinated manner. It is necessary to have more accurate data on the recording of AEs in protocols to enhance transparency and consistency, as well as to improve practice. Finally, and to facilitate this process, there is a need for standards for data collection.
