This is an ethically reviewed and approved protocol for a cross-sectional descriptive design to estimate the prevalence of psychosocial effects of post-COVID-19 lockdowns on children aged 12 to 17, utilizing the Strengths and Difficulties Questionnaire (SDQ). Participants are adolescents enrolled in Junior High School, Education High School, or Senior High School at a private institution in Manila. Individuals already diagnosed with cognitive impairments or psychological disturbances were excluded.

We are publishing the copy of our ethically approved proposal to increase transparency of our study. We believe that investigating the psychosocial development of adolescents to explain the effects of the COVID-19 pandemic is a unique approach to understanding its effects on their mental health. We hope that by making our protocol available, other investigators may be able to replicate our study in other subgroups of this population (ie, public schools, street children, home-schooled kids, etc.). It is our hope that if the study is replicated enough, we can have sufficient data to do a meta-analysis and get more accurate estimate of the effects.
