Health care providers can offer different treatment formats of WHO’s recommended, structured psychological interventions for adults and older adolescents with depressive disorder. These include behavioural activation, cognitive behavioural therapy (CBT), interpersonal psychotherapy (IPT), problem-solving treatment as an adjunct treatment (e.g. in combination with antidepressants). Different treatment formats for consideration include (a) individual and/or group face-to-face psychological treatments delivered by professionals and supervised lay therapists, as well as (b) self-help psychological treatment. While face-to-face psychological treatment or guided self-help psychological treatment are likely to have better outcomes than unguided self-help, the latter may be suitable for those people who either (a) do not have access to face-to-face psychological treatment or guided self-help psychological treatment or (b) are not willing to access such treatments
