Primary Outcomes (End Points) Attitudes towards evidence-informed policy making (EIPM), perception on use of AI tools in EIPM, EIPM practice Attitudes towards evidence-informed policy making (EIPM), perception on use of AI tools in EIPM, EIPM practice, platform usage
Primary Outcomes (Explanation) Attitudes toward and perceptions of evidence-informed policymaking (EIPM) will be measured using a 28-item questionnaire. Latent constructs will be derived through factor analysis. EIPM practices will be measured using a single survey item. Attitudes toward and perceptions of evidence-informed policymaking (EIPM) will be measured. EIPM practices will be measured using a single survey item and platform usage.
Experimental Design (Public) The target population consists of mid- and senior-level government officials who are responsible for drafting or reviewing policy documents, including policy briefs, policy reports, and strategy papers. Approximately 60 officials will be randomly assigned to either the treatment group or the control group, with 30 individuals in each group. As part of a broader partnership with the Sri Lankan government, an additional group of approximately 30 government officials will participate in a voluntary capacity-building program that includes access to the AI platform and complementary training activities. The impact of this capacity-building intervention will be evaluated separately using a mixed-methods approach combining quantitative and qualitative data. The target population consists of mid- and senior-level government officials who are responsible for drafting or reviewing policy documents, including policy briefs, policy reports, and strategy papers. 94 officials will be randomly assigned to either the treatment group or the control group, with 47 individuals in each group.

Planned Number of Observations 60 government officials in the RCT. 94 government officials in the RCT.
Sample size (or number of clusters) by treatment arms 30 individuals in the treatment group and 30 individuals in the control group. 47 individuals in the treatment group and 47 individuals in the control group.
Power calculation: Minimum Detectable Effect Size for Main Outcomes With n = 30, the minimum detectable effect size (Cohen's d) is 0.73. The study is powered to detect a large standardized effect. With n = 47, the minimum detectable effect size (Cohen's d) is 0.58. The study is powered to detect a medium to large standardized effect.
Secondary Outcomes (End Points) Text data from policy documents
Secondary Outcomes (Explanation) Use of research and policy evidence in policy documents will be assessed based on a coding manual.
