The MCSS-26©


The MCSS-26© [previously known as the Manchester Clinical Supervision Scale©] is a research questionnaire, which was specifically developed during the landmark UK Clinical Supervision Evaluation Project to measure the efficacy of Clinical Supervision [CS], from the perspective of the Supervisee.

The original 36-item version of the scale was launched by the Department of Health, in London, in 2000. Since then, utilising merged data derived from multiple international MCSS© research studies, the Directors of White Winstanley Ltd have conducted and published a rigorous series of Rasch analyses [see Selected Publications].

The findings re-confirmed the robust psychometric properties of the research instrument and justified a re-modelled version; named the MCSS-26©. The current scale contains ten fewer questions, with increased structural integrity. In addition, the 6 subscales of the MCSS-26© have also been found to tap into the 3 domains [Formative, Normative and Restorative] of one of the most influential and widely adopted frameworks for Clinical Supervision, the so-called ‘Proctor Model’1.

The MCSS-26© can be used to evaluate the provision of Clinical Supervision to a variety of health/social care professions and fieldwork locations.

To date [2021], it has been translated into 10 languages, other than English and used in upwards of 190 licensed MCSS©/MCSS-26© evaluations of CS have been conducted in 18 countries, worldwide.

No other CS-specific questionnaire has yet withstood such close analytic scrutiny, nor publicly reported such findings, to make stepwise contributions to the methodological literature and to increase the substantive confidence of end-users. The MCSS-26© remains distinctive in both respects.
