(2) What are the effects on financial outcomes of financial coaching embedded within community settings? (3) What are the effects on financial outcomes of financial coaching embedded within healthcare settings? (4) What are the effects on health/well‐being‐related outcomes of financial coaching embedded within community settings? (5) What are the effects on health/well‐being‐related outcomes of financial coaching embedded within healthcare settings? (6) What study or intervention characteristics are associated with variation in the effects of financial coaching (i.e., design (RCT and QED), publication status (published or unpublished), dosage and duration of financial coaching intervention (continuous variable), age, financial coaching elements, and setting of intervention (healthcare or non‐healthcare)?
