A systematic approach to searching the literature was initially undertaken to identify multidimensional tools used in perinatal mental health assessment, in both the cited and grey literature.
The disease-specific, multidimensional tools commonly used in lung cancer studies, such as the Lung Cancer Symptom Scale (LCSS) used by Hanna et al. [ 6] in a study which compared second-line treatment with pemetrexed versus docetaxel, were too complex for use in a routine clinical practice setting.
20 Multidimensional tools such as TOPS (Treatment Outcomes in Pain Survey instruments 21) or the standard questionnaire of the German Pain Society 22 have been developed but those processes were not consensus driven.
Very few multidimensional tools are available for measurement of pain in children and adolescents.
The psychometric properties of six multidimensional tools and/or criteria were assessed.
It should be noted that the main observations discussed in [ 11], which were extracted separately from the two datasets by both classical multidimensional tools (hierarchical clustering and PCA) and standard test procedures, are also highlighted by kernel PCA graphical representations.
The NASA-TLX workload measure is a multidimensional tool that rates responses in accordance to six factors: 1) mental demand, 2) physical demand, 3) temporal demand, 4) effort, 5) performance, and 6) frustration (Table 2).
Where items within a scale measure different elements of patient experience (as in this multidimensional tool) a moderate Cronbach's alpha (i.e. approximately 0.5), rather than a high alpha (i.e. >0.7), is expected.
This index is a multidimensional tool measuring frailty and prognostic indicators in health-related outcomes.
Such tools are complementary, and combining a unidimensional (e.g., EPDS) and multidimensional tool (e.g., the ANRQ, ARPA) in this way allows for both cross-sectional and contextual/longitudinal factors to be assessed.
