Non-experimental impact evaluations are so-called because they do not involve a comparison group that does not have access to the intervention. The method used in non-experimental evaluation is to compare intervention groups before and after implementation of the intervention.
If the assessment is favourable, and the proposed policy is enacted—after a suitable length of time for the policy to gain traction—it might be followed by an impact evaluation; ideally, assessed impacts before the fact and evaluated impacts after the fact are not wildly divergent. In some cases, impact becomes politicized due to a change ...
Interrupted time series analysis (ITS), sometimes known as quasi-experimental time series analysis, is a method of statistical analysis involving tracking a long-term period before and after a point of intervention to assess the intervention's effects.
The monitoring is a short term assessment and does not take into consideration the outcomes and impact unlike the evaluation process which also assesses the outcomes and sometime longer term impact. This impact assessment occurs sometimes after the end of a project, even though it is rare because of its cost and of the difficulty to determine ...
Evaluation, monitoring and follow-up - process and impact evaluation of the HIA and the monitoring and management of health impacts The main objective of HIA is to apply existing knowledge and evidence about health impacts, to specific social and community contexts, to develop evidence-based recommendations that inform decision-making in order ...
Environmental impact assessments commenced in the 1960s, as part of increasing environmental awareness. [6] An EIA is prepared to estimate the effects of a proposed development or construction project. EIA provides technical evaluations that are intended to contribute to more objective decision making.
The PRECEDE–PROCEED model is a cost–benefit evaluation framework proposed in 1974 by Lawrence W. Green that can help health program planners, policy makers and other evaluators, analyze situations and design health programs efficiently. [1]
Social impact assessment (SIA) is a methodology to review the social effects of infrastructure projects and other development interventions. Although SIA is usually applied to planned interventions, the same techniques can be used to evaluate the social impact of unplanned events, for example, disasters, demographic change, and epidemics.
