Table 1 Properties of Berlin and Fresno test

From: Study protocol of psychometric properties of the Spanish translation of a competence test in evidence based practice: The Fresno test

Test property Measure used Performance of Berlin test [10] Performance of Fresno test [9]
Content validity (test covers entire topic of interest) Expert opinión Expert opinion (five teachers in EBP) Revisions based on experts' suggestions
Inter-rater reliability (degree to which 2 scorers rate a single performance similarly) Inter-rater correlation Total score 0.96 (IC 95%: 0.92–0.98) Ranged from 0.76 to 0.98 for individual items, total scores 0.98
Internal reliability (degree to which all test questions on the test measure a single construct) Cronbach's α average of all possible split half correlations 0.75 0.88
Item difficulty (relative difficulty of each item) % of candidates who answer achieve a passing score Not given Ranged from moderate (73%) to difficult (24%); no easy items
Item discrimination (ability of each item to discriminate between those with overall high scores and those with overall low scores) Item discrimination index (ranges from -1.0 to 1.0) Not given Ranged from 0.41 to 0.86, no items had negative or weak discriminations
Construct validity (evidence that the test measures the construct it intends to) Mean scores of experts and novices compared by t test Significant difference, higher expert scores than novices Significant difference, higher expert scores than novices
