Table 2 Identified Research Gaps

From: Using media to impact health policy-making: an integrative systematic review

Domain of evidence gaps Gaps identified
Study design • Lack of well-designed comparative studies, particularly on social media
Intervention • Limited evidence on effects of media interventions independent of other interventions (i.e., published studies assessed media as part of multi-component intervention)
• Limited evidence on planned media interventions (i.e., most published studies assessed media coverage that was not planned)
• Limited description of media interventions assessed
Study setting • Limited evidence from low and middle-income countries
Outcomes • Lack of rigorous evaluation of outcomes (e.g., assessed based on perceptions of respondents about effectiveness of media interventions and not actual evaluation of effectiveness)
• Limited evidence on the impact on policy stages
• Lack of studies evaluating the policy evaluation stage
