OBJECTIVE: To evaluate the methodological quality of research on cognitive
rehabilitation after traumatic brain injury (TBI). DATA SOURCES: Secondary
analysis of studies identified in prior systematic reviews of cognitive
rehabilitation. STUDY SELECTION: Randomized controlled trials (RCTs) and
observational studies involving exclusively or primarily participants with TBI.
DATA EXTRACTION: Criteria for evaluating methodological quality were adapted from
prior reviews of rehabilitation research. These criteria were modified to be
relevant to cognitive rehabilitation research. Sixteen criteria for evaluating
the quality of RCTs were applied: 8 relating to the internal validity of studies,
5 descriptive criteria, and 3 statistical criteria. Twelve of these criteria were
used to evaluate non-RCT observational studies. DATA SYNTHESIS: Thirty-two RCTs
and 21 observational studies were independently reviewed and rated by 2 of the
authors. Initial agreement between raters for individual studies ranged from 57%
to 100%. Interrater reliabilities based on the kappa statistic indicated moderate
to substantial agreement. CONCLUSIONS: Several high-quality RCTs support the
effectiveness of interventions for attention, communication skills, and executive
functioning after TBI. Several high-quality observational studies support the
effectiveness of comprehensive-holistic rehabilitation after TBI, including
improvements in participation outcomes. The proposed criteria appear useful for
evaluating the quality of research on cognitive rehabilitation and improving the
design and reporting of future research in this area.
