Establishing the concurrent validity
of the Clinical Outcome in Routine
Evaluation-Learning Disabilities scale

Abstract
Purpose –Individuals with an intellectual disability (ID) develop mental health difficulties at similar rates to
individuals in the general population. Using Patient Reported Outcome Measures can help track deterioration
and improve the outcomes of individuals seeking help for their difficulties. The Clinical Outcome in Routine
Evaluation-Learning Disabilities (CORE-LD) is a multi-trait measure of psychological distress which has
shown moderate test-rest reliability. However, the CORE-LD is yet to be validated for the population it was
designed for. Therefore the purpose of this paper is to establish the concurrent validity of the CORE-LD in a
population of individuals with a diagnosis of mild–moderate ID.
Design/methodology/approach –Participants with a diagnosis of mild–moderate ID, as well as other
co-morbidities, were recruited from two UK inpatient hospitals and asked to complete the CORE-LD and its
general population counterpart the Clinical Outcome in Routine Evaluation-Outcome Measure (CORE-OM).
Findings –Statistically significant differences were found regarding the CORE-LD across gender, with
females scoring higher on the CORE-LD than males. There was no significant difference between security
levels. The overall mean scores on each measure were moderately correlated. The data from this analysis
suggest a significant positive correlation (r
s
¼0.68).
Originality/value –This initial study’s findings have demonstrated the CORE-LD may have concurrent
validity, and further replication studies in larger and more diverse samples are needed.

Introduction
An intellectual disability (ID) is defined by the ICD-10 as “a condition of arrested or incomplete
development of the mind, which is especially characterised by impairment of skills manifested during
the developmental period, which contribute to the overall level of intelligence, i.e. cognitive, language,
motor and social abilities”(World Health Organisation, 1992). Similarly, The Diagnostic and Statistical
Manual of Mental Disorders-5 define an ID as significant impairment in three areas, social skills,
conceptual skills and adaptive skills (American Psychiatric Association, 2013).
Individuals with a diagnosis of ID have an elevated risk of developing mental health difficulties or
live in circumstances, which are associated with an increased risk of developing mental health
problems (Hatton et al., 2017). As such, individuals with a diagnosis of ID develop mental health
difficulties similarly or quicker than their general population counterparts (Sheehan et al., 2015).
In response to the above, mental health provision has been increased for individuals with a
diagnosis ofID (Department of Health and SocialCare, 2011). To afford these services, there is an
expectation of effectiveness from the Government (Department of Health and Social Care, 2017).
To demonstrate effectiveness the use of outcome measures is employed. Aside from
demonstrating effectiveness, routine use of outcome measures has been shown to increase
