Many parents suffer from depression after having a baby. This can be both debilitating and distressing for the parent(s) and their families. Depression in the postpartum period often goes unrecognised, leaving parents struggling with its impact. Early identification and treatment of postpartum depression is essential in order to promote the best outcome possible for parents and their babies. This book provides a step-by-step guide of an evidence-based treatment for postpartum depression and aims to be a resource for therapists treating parents using this approach. The programme is divided into four modules which address: (i) assessment and goal setting - covering strengths and values as well as risks and challenges, (ii) behavioural activation -encouraging helpful behaviours that reduce the depressive symptoms as well as how to counter unhelpful avoidance, (iii) managing unhelpful thinking - working out how to address rumination and build self-compassion and finally (iv) relapse prevention - working out what has helped and how to stay well. As well as these four standard modules there are also additional sessions covering how to manage distressing intrusive thoughts and dealing with traumatic images/memories of the birth. This book can be used in conjunction with the accompanying workbook for the parent(s) undertaking this treatment including detailed worksheets and resources.
