Quality assessment
Citation | Was the final sample size ≥ N = 300? | Was the response rate ≥ 70%? | Did the authors use a validated measure of generalised anxiety, with valid cut-offs for classification of anxiety? | Was the target population defined clearly? (e.g. location of sample, any eligibility criteria) | Was there complete, random (stratified or non-stratified), or consecutive recruitment? | Were the confidence intervals (CI) or standard error (SE) reported? | Was the targeted sample representative, or the report presents evidence that the results can be generalized to the general undergraduate population? (could include weighting to restore representativeness) | Total quality score (out of 7) |
