Validation of the Norwegian Versions of the Implementation Leadership Scale (ILS) and the Multifactor Leadership Questionnaire (MLQ) in a Mental Health Care Setting
Abstract Background: The implementation of evidence-based practices (EBPs) is of crucial importance in health care institutions and requires effective management from the leaders. However, there is a lack of sufficient assessment tools to evaluate the degree to which the employees´ rate how well their leaders are at implementing EBPs. This emphasizes the need for a validated and widely used implementation scale for EBPs. Methods: The current study evaluated the psychometric properties of the Multifactor Leadership Questionnaire (MLQ) and the Implementation Leadership Scale (ILS) in a Norwegian mental health care setting. Results: Results from confirmatory factor analyses indicated that the MLQ and ILS were valid instruments for measuring general and implementation leadership. The scales demonstrated good convergent validity. In addition, attitudes towards EBPs did not seem to be associated with the ILS and the MLQ, further supporting the applicability of the instruments. Conclusions: The two scales demonstrate good psychometric properties in a Norwegian mental health care setting, which suggests that the MLQ and ILS are valid and reliable tools for measuring leadership in an implementation setting. More research is highly needed to disentangle the link between perceived leadership and objective measures of successful implementation of EBPs. Trial registration: NSD 690133, NSD 60059/3/OOS
