The Experience of Service Questionnaire (ESQ, formerly CHI-ESQ) was developed by the then Commission for Health Improvement (now the Health Care Commission) as a means of measuring service satisfaction in Child and Adolescent Mental Health Services. The CHI-ESQ was originally used as an anonymous measure for one-off audits of service delivery but CORC recommends that it should be used routinely in conjunction with other core measures so that a family’s experiences with the service can be understood alongside the child’s symptom reduction.
The ESQ consists of 12 items and three free text sections looking at what the respondent liked about the service, what they felt needed improving, and any other comments.
|Reliability||Degree to which respondents in a similar sample had similar scores||No information available at present.|
|Test-retest reliability||Degree to which the same respondents have the same score after period of time when trait shouldn’t have changed||No information available at present.|
|Concurrent validity||Correlation of the measure with others measuring the same concept||No information available at present.|
|Discriminant validity||Lack of correlation with opposite concepts||No information available at present.|
|Construct validity||Degree to which a test measures what it claims to be measuring||Brown et al. (2014) reported that the ESQ items can be grouped into two underlying constructs: Satisfaction with Care and Satisfaction with the Environment. The Satisfaction with Care scores showed good precision, differentiating well between less satisfied children, young people and parents, while the Satisfaction with Environment construct did not show sufficient measurement precision, and it is therefore not recommended to be used on its own.|
Information on the development progress can be found in this Commission for Health Improvement Evaluation Report.
Parents/carers and young people aged 9-18 can fill out the ESQ.
There are no known translations of the ESQ.
There are three versions of the ESQ:
- ESQ Child Self-report for 9-11 year olds
- ESQ Child Self-report for 12-18 year olds
- ESQ Parent/carer report
Further versions of the parent/ carer report have been developed:
Scoring and Interpretation
The ESQ consists of 12 items rated "Certainly True" (= 1 under CORC Snapshot; = 3 under CORC+), "Partly True" (= 2) and "Not True" (= 3 under CORC Snapshot; = 1 under CORC+) and three free-text sections looking at what the respondent liked about the service, what they felt needed improving, and any other comments. The ESQ Addendum consists of three items which are scored in the same way as the ESQ.
Adding up the "Certainly True" responses for each item across a sample can provide information on respondents' subjective satisfaction with the service.
The Satisfaction with Care construct can be obtained by adding up items 1,2,3,4,5,6,7,11 and 12, and the Satisfaction with Environment construct can be obtained by adding up items 8,9 and 10 (Brown at al., 2014)
If you are planning to use this measure for the delivery and improvement of health and/or social care, a license to incorporate it into electronic systems can be obtained from NHS Digital. Please note that licenses obtained via this route may be restricted to particular territory (e.g. England, UK). If planning to use the measure outside of England, you may wish to contact NHS Digital to clarify the geographical scope of the licence.
