Implementation outcome definitions used for systematic review based on Proctor's implementation outcome framework (Proctor et al., 2011)

Implementation outcome	Narrative definition	Population reporting	Stage of implementation reported	Type of data reporting	Specific study inclusion criteria	Exclusion criteria
Acceptability	Satisfaction with various aspects of intervention or implementation strategy	Consumer; Implementer	Pre-implementation; During implementation; Post-implementation	Qualitative; Quantitative	Must report formal analyses of quantitative or qualitative results of satisfaction with specific depression intervention or implementation strategy being tested	Excluded if general service satisfaction not linked to specific depression intervention or implementation strategy; Excluded if descriptive without formal analyses of client or consumer perceptions
Adoption	Initial implementation, utilization, or intention to try intervention or implementation strategy	Implementer; Organization; Setting	Pre-implementation; During implementation	Quantitative	Must be able to calculate numerator and denominator (no. of implementers, organizations, or settings adopting or intending to adopt/no. of eligible)	Excluded if qualitative results on use or intent to use not allowing calculation of proportion adopting
Appropriateness	Perceived fit, relevance, compatibility, usefulness, or practicability of intervention or implementation strategy	Consumer; Implementer; Organization; Setting	Pre-implementation	Qualitative; Quantitative	Must report formal qualitative or quantitative analyses of pre-implementation perceived fit of specific depression intervention or implementation strategy being tested	Excluded if general service appropriateness not focused on intervention or strategy of interest; Excluded if descriptive without formal analyses of client or consumer perceptions
Feasibility	Actual fit, relevance, compatibility, usefulness, or practicability of intervention or implementation strategy	Consumer; Implementer; Organization; Setting	During implementation; Post-implementation	Qualitative; Quantitative	Must report formal quantitative or qualitative analyses of post-implementation actual fit of specific depression intervention or implementation strategy being tested	Excluded if general service feasibility not focused on intervention or strategy of interest; Excluded if descriptive without formal analyses of client or consumer experiences
Fidelity	Degree to which an intervention or implementation strategy was implemented as intended	Implementer	During implementation	Quantitative	Must report formal analyses of fidelity to intervention or implementation strategy of interest; must be able to calculate numerator and denominator of (no. of implementers achieving fidelity/no. of implementing)	Excluded if general quality of care or delivery not focused on intervention or strategy of interest; Excluded if qualitative results on fidelity that do not allow calculation of proportion achieving fidelity
Cost	Cost of intervention or strategy delivery	Implementer; Organization; Setting	Post-implementation	Quantitative	Must report actual dollar amounts of implementation cost of intervention or implementation strategy of interest	Excluded if general costs of service delivery not tied to intervention or strategy of interest
Penetration	Degree of integration of intervention or implementation strategy within service setting and subsystems in non-controlled settings	Consumer; Implementer; Organization; Setting	During implementation; Post-implementation	Quantitative	Must be able to calculate numerator and denominator of either (no. of implementers, organizations, or settings delivering intervention or implementation strategy/no. of eligible) or (no. of consumers using a given intervention/no. of eligible); Depression intervention must be under routine institutional implementation, rather than controlled by researchers or external implementers	Excluded if results do not allow calculation of proportion utilizing intervention or implementation strategy with depression intervention delivered under routine conditions; Excluded if depression intervention under researcher-controlled implementation and not institutional implementation
Sustainability	Extent to which an intervention or implementation strategy is maintained within service setting's ongoing, stable operations	Organization; Setting	During implementation; Post-implementation	Qualitative; Quantitative	Defined as measurement of maintenance (either quantitative or qualitative) or ‘intent-to-continue use’ after initial pilot research-based funding has been rescinded and implementation is progressing under routine care conditions	Excluded if measurement only occurred during pilot research-based funding; Excluded if general sustainability not targeting intervention or implementation strategy of interest
