Hence, we need to find a valid instrument (Z_{in}) which satisfies two conditions, known as instrument relevance and instrument exogeneity.
This condition corresponds to the instrument relevance assumption in the empirical section, which assures a sufficient correlation between the endogenous variable, i.e., wage cuts, and the instrumental variable, i.e., the status of a performance-based payment system.
The participative process used to build the tool is described and the consequences of the research are discussed: psychometric properties of the instrument; relevance for the caregivers who are involved in the daily support of a disabled person; use of this tool to guide a disabled person's project or psychoeducation.
The objective was to translate the instrument relevance regarding conceptual and cultural equivalence and strive for simplicity.
In a recent study of clinician's behaviour and attitudes towards routine outcome measurement, administrative load and instrument relevance were highlighted as barriers to implementation [ 47].
Unfortunately, criteria for PRO scale selection are occasionally restricted to issues of availability or familiarity rather than considerations of instrument relevance or quality.
Responses to the EBP2 were able to distinguish groups with different levels of prior EBP exposure for three of the five domains of the instrument (Relevance, Terminology and Confidence, ANOVA p < 0.001 to 0.004).
Table 2 presents the policy scorecard of regulatory instruments of relevance to mental health and psychosocial risks applicable to the EU member states.
When asked about the instrument's relevance, a substantial portion of the sample provided mixed responses, stating that the EQ-5D could be relevant to other and possibly more severe patients, but not to their own personal experience.
