Why is the external validity of single-subject research frequently questioned by critics?
If a single-subject study demonstrates that a specific behavioral intervention successfully reduces self-injury in two children, a critic questioning the study's external validity would argue that these results may not necessarily apply to other children in the broader population.
A researcher conducts a single-subject study with three children to evaluate a new social-skills training program. Match each element of this research scenario to its role in a critique of the study's external validity.
A researcher finds that a new intervention successfully reduces social anxiety in two college students. Arrange the following logical steps to represent the process of analyzing why these findings might not apply to the broader population.

An educational psychologist conducts a single-subject study and demonstrates that a specialized visual-schedule intervention successfully reduces transition-related anxiety in two specific children with developmental delays. If a critic questions the external validity of these findings, what is the core of their concern?
A peer reviewer evaluates a single-subject study involving two participants and concludes that the findings should not be used to inform national healthcare guidelines. This judgment is based on the study's inherent deficiency in _____ validity.
Critics of single-subject research frequently question its external validity because of the difficulty in knowing whether the observed treatment effects will successfully _____ to other individuals in the broader population.
A clinical psychologist publishes a single-subject study showing that a new behavioral intervention successfully reduces self-injury in two children with intellectual disabilities. If they claim this study proves the treatment will be effective for all children with intellectual delays, this claim is invalid because it ignores the inherent external validity concerns caused by the small sample size of single-subject designs.
A researcher publishes a single-subject study examining a treatment for self-injury. Match the elements from the study's critique to their correct descriptions or roles in evaluating external validity.
A researcher claims a self-injury treatment is ready for general use based on a single-subject study of two children. Order the steps an evaluator should take to assess the external validity of this claim, from the initial observation to the final evaluation.
