Overly stringent inclusion criteria affecting external validity |
| Number of systematic reviews included | 1 |
| Summary of Findings | The systematic review methods used produced an evidence base that did not inform the development of guidance to the extent that it could have done due to: (i) an emphasis upon internal research validity to produce an evidence base with an emphasis on short-term interventions at the level of the individual; (ii) criteria for appraising the external validity of studies were not developed sufficiently; and (iii) the systematic review of evidence and development of guidance were strongly reliant upon the judgement of reviewers and committee members. |
