Abstract Antimicrobial stewardship (AMS) interventions promote optimised use of antimicrobials by healthcare professionals. In 2019–2020, the Commonwealth Partnerships for Antimicrobial Stewardship (CwPAMS) supported 12 global health partnerships in low‐ and middle‐income countries to co‐develop education and training interventions to improve AMS practices amongst hospital staff. This study aimed to describe six of the CwPAMS health partnerships' target behaviours and behaviour change techniques (BCTs) within their planned AMS interventions. Content analysis extracted behaviours and BCTs from partnership materials. Techniques used by partnerships with ( n = 2) and without ( n = 4) an embedded behavioural scientist were compared, to understand their added value. Nineteen AMS related behaviours for hospital staff were targeted; most commonly hand hygiene and antibiotic prescribing behaviours. Twenty‐three BCTs were coded, with instructing participants on how to perform the behaviours the most prominent across all, including partnerships with a behavioural scientist. Intervention materials did not always report the context of the intervention being delivered, including who was delivering it and the target. Behaviours for change were also often not specified. Partnerships varied in reporting their content and specific behaviours, impacting replicability of their interventions, and limiting knowledge exchange. An AMS behaviour change intervention resource is recommended to support clear specification of prospective AMS interventions.
