Final answer:
Outcome evaluations can be challenging due to the need for long-term follow-up assessments and participant engagement.
Step-by-step explanation:
Outcome evaluations can be intimidating for evaluators because they often rely on long-term follow-up assessments. This kind of evaluation requires having appropriate systems in place to effectively track and measure the outcomes of a program or intervention. Evaluators may feel like they can provide the necessary resources and support, but ultimately, the success of an outcome evaluation depends on the participants' willingness to actively engage and comply with the evaluation process.
