According to the rating of the documented psychometric properties (Table 4), 16 (80%) test instruments complied with both validity and reliability criteria, based on the information reported by authors of the retained articles and the test publications. For all the instruments at least one of the three validity criteria was reported. Content validity, as determined by a review of expert judges, was reported for thirteen (65%) of the 20 instruments. It was found that evidence for internal structure was reported for fifteen (75%) instruments through performing statistical analysis (e.g., factor analysis, internal consistency reliability). Authors outlined relations to other variables based on predictive and/or concurrent, convergent and/or discriminant validity evidence for ten (50%) measurement instruments. The highest instrument validity score (3 out of 3) was obtained for the AST 6–11 (Bös, 2000), the MOT 4–6 2 (Zimmer, 2016), the BOTMP-2 (Bruininks & Bruininks, 2005), the MABC-2 (Henderson, Sugden, & Barnett, 2007), the MAND2 (McCarron, 1997) and the TGMD-2 (Ulrich, 2000), meaning that contributions reporting on these instruments provided all three sources of validity evidence. Authors of retained articles and test publications outlined estimates of reliability for 16 (80%) of the 20 identified test instruments. Inter-rater reliability was reported for ten (50%) test instruments and internal consistency for eight (40%) test instruments. The most common form of reliability testing used was test-retest reliability, found to be present in fourteen of the papers (70%). Papers related to the BOTMP-2 (Bruininks & Bruininks, 2005), the MABC-2 (Henderson et al., 2007), the PDMS-2 (Folio & Fewell, 2000), the MUGI (Ericsson, 2008) and the TGMD-2 (Ulrich, 2000) provided the highest reliability score (3 out of 3).
