Ecological validity of neuropsychological interventions: A systematic review

Abstract

Background

The concept of ecological validity (EV) in neuropsychological interventions (NI) has been consistently advocated, but there is a lack of reviews focused on how EV is operationalized in NI programmes. This review aims to address this gap by exploring the outcome measures more commonly used for assessing EV and to understand the main characteristics of programmes with good EV.

Method

A literature search was conducted to identify studies that examined the EV of NI programmes, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Collaboration Guidelines.

Results

A total of twenty-seven studies were included in this review. Among these, only three studies explicitly described the procedures used to assess EV. Additionally, almost half of the studies assumed that interventions had good EV based on the characteristics of the programmes. The inconsistent assessment of EV of NI programmes prevented the identification of specific characteristics of programmes demonstrating good EV.

Conclusion

This systematic review reveals a significant gap in the literature concerning the operationalization of EV within the field of NI. Further research is required to establish a consistent definition of EV in the context of NI and to develop criteria for its effective operationalization.
