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 |
