Research ethics

All new data collection studies conducted with the ALSPAC cohort require ethical approval. Applications for ethical approval must be developed with ALSPAC.

We will work with you to achieve effective participant involvement from our ALSPAC Participant and Public Advisory Panel (APPAP). We will ensure studies collecting biological samples have the appropriate consent and participant information to comply with the requirements of the Human Tissue Act.

Studies which do not involve human tissue, use of NHS premises or ionizing radiation should be submitted to the ALSPAC Ethics and Law Committee (ALEC).
