Competing Interests

One of the investigators, Joshua Langberg, receives royalty payments from the National Association of School Psychologists for books about the HOPS program, which is being evaluated in this study. Thomas Power and Jennifer Mautone, investigators on this study, have a financial interest in a questionnaire (HPQ-T) being used in this study. The questionnaire was included in an appendix of a book published by Guilford Press in 2024 for which they receive royalty payments. This measure has already been evaluated and is not being evaluated or further developed in this study. Study investigators will continue to monitor competing interests and report any changes to the Office of Compliance and Privacy at CHOP. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
