    2024/12/01 | National Institute for Occupational Safety and Health (NIOSH)
    Program evaluations that lack experimental design often fail to produce evidence of impact because there is no available control group. Theory-based evaluations can generate evidence of a program's causal effects if evaluators collect evidence along the theorized causal chain and identify possible competing causes. However, few methods are availabl ...
