This book is a fine amalgamation of theoretical concepts and practical dimensions illustrated through case studies. These case studies from India demonstrate the efforts to bridge the gap between ‘what should be done’ and ‘what has been done’. Each one brings with it years of experience and efforts to address burning public health issues. These would serve as food for thought for discussions during any academic or research program. The contents of this book will equip readers to: • Describe the different types of public health interventions. • Frame an appropriate research question on a public health intervention, including relevance and expected outcome. • Describe approaches to designing a public health intervention. • Formulate the implementation plan of an intervention. • Develop a monitoring and evaluation framework of a public health intervention. • Choose the most appropriate study design to test the effectiveness of an intervention. • Assess scalability of an intervention.
