The contents are of interest for all professionals working in the field of perinatal mental health. Special attention in the reprint is given to three main domains: clinical characteristics of perinatal depression and anxiety in women and men; psychometric properties and usefulness of screening tools; and types of intervention. The first area focuses on the investigation of prevalence, risk factors and predictors of perinatal depression and anxiety, considering different samples of women and/or men, during the prenatal and postpartum period; a glance is also given to perinatal mental health difficulties experienced during the COVID-19 pandemic. The second area is focused on the description of psychometric properties of tools for the detection and screening of perinatal anxiety and depression. This section includes contributions regarding: comparisons among different tools, further validation of already existing questionnaires and validation of new instruments, which could enhance the early detection of depressive and anxiety symptoms. The third area focuses on different approaches of intervention to reduce perinatal depression and anxiety, including gender-transformative interventions to address perinatal mental health and clinical guidelines for the pharmacological management of both depression and anxiety.PsychologybicsscEdinburgh Postnatal Depression Scale (EPDS)Slovakiavaliditypostpartum depressionpregnancyCOVID-19pandemic stresscorrelates of stressinfectionpreparednessInsomnia Symptom Questionnairesleep disordersperinatal periodinternal consistencyconvergent validitypredictorslongitudinal studyanxietychildbirth experienceclinical practice guidelinedepressionantidepressantpsychotropic medicationsperipartumchildbirthfearassessmentbirthquestionnaire developmentcaesareanvaginalchildbirth anxietyanxiety in pregnancySARS-CoV-2pandemicsupportperinatal carechildbirth schoolperinatalscreeningvalidationEPDSperinatal mental healthanxiety disordersperinatal anxietyfear of childbirthpostnatalidentifyingGADquestionnairesstructural validityperinatal depressionresponsivenessonline and offline interventionpostpartum womene-health technologysocial stigmasocial supportstudy protocolfatherspreterm birthseverity of prematurityELBWVLBWparenting stresspartner’s influencegender transformative interventionsscoping reviewLMICPsychologyAgostini Francescaedt1279881Agostini FrancescaothBOOK9910639987603321Screening and Treatment of Perinatal Depression and Anxiety3016106UNINA
