The review eligibility criteria.

We included:	We excluded:
Randomized controlled trials published in English (randomized crossover trials and cluster-randomized trials);	Studies where less than 70% of participants met diagnostic criteria for anxiety, depression, or trauma-related disorders according to Diagnostic and Statistical Manual of Mental Disorders (DSM), and International Classification of Diseases (ICD) criteria, via clinical interview or validated self-report questionnaire (where self-report questionnaires were used, we estimated clinical caseness using data provided in the study, and established cut-offs for particular measures);
Studies of women aged over 16 of any ethnicity in the perinatal period (defined as pregnant or up to 2 years postnatal at the time of the baseline assessment);	Studies where the intervention was focused around the loss of a child;
Studies where individual cognitive behavioral therapy (CBT) was the active intervention, described in sufficient detail and meeting our definition of CBT (defined as established models of cognitive and/or behavioral therapy, with cognitive therapy built around the concept that the way we think affects how we feel emotionally and how we seek to behave, and behavioral therapy being based on changing behavior, for example behavioral activation or exposure-based work), delivered with or without treatment as usual;	Studies of brief interventions (which we defined as sessions lasting less than half an hour or of a duration of three or fewer sessions);
Studies where a reduction in anxiety, depression, or trauma-related symptoms was the primary aim of the intervention (including where anxiety, depression, or trauma-related disorders were comorbid disorders);	Studies where CBT for the targeted problem was one part of a wider multicomponent psychosocial intervention;
Studies of CBT delivered face-to-face or remotely, including guided self-help, such as internet-based programs with guidance either in person, by telephone or by email/messenger, (automated instant messaging was not included);	Studies testing psychoeducation, mindfulness-based interventions and EMDR.
Studies comparing CBT with waitlist, repeated assessment, treatment as usual, face-to-face and internet-based psychological therapy which was non-CBT-based (for example including Eye Movement Desensitization and Reprocessing (EMDR), supportive therapy, nondirective counseling, psychodynamic therapy, and present-centered therapy).
