“…Furthermore, staff members who feel that they are permitted to make mistakes in providing support to residents are better able to learn from these mistakes and adjust their actions in subsequent incidents involving challenging behaviour ( Knotter et al., 2013 ; Olivier-Pijpers et al., 2019 ). Exosystem aspects that seem to be associated with challenging behaviour include the management's leadership style, coaching by psychologists, a supportive team environment for care professionals, a positive organisational culture and the translation of personnel policies into daily practices; all of these aspects provide the staff guidance on proper support of residents, resulting in the occurrence of fewer incidents involving challenging behaviour ( Dilworth et al., 2011 ; Allen et al., 2013 ; Deveau and McGill, 2016 , 2019 ; Bigby and Beadle-Brown, 2018 ; McGill et al., 2018 ; Olivier-Pijpers et al., 2018 ; Olivier-Pijpers et al., 2019 ). Macrosystem aspects linked to challenging behaviour include negative media attention to bad practices, which results in a focus on control instead of trust of staff members to support residents, in turn negatively influencing challenging behaviour ( Olivier-Pijpers et al., 2019 ).…”
