Development and validation of the Nottingham Leisure Questionnaire (NLQ)

Objectives: To reduce the length of the Nottingham Leisure Questionnaire (NLQ) in order to make it more suitable for postal use, and to evaluate its test-retest reliability, sensitivity, stability and validity in relation to other measures of activities of daily living (ADL), mood and handicap. Method: The NLQ was shortened and the response categories collapsed. Results from a previous trial which had used the NLQ were reanalysed to establish if significant group differences were maintained. The new version of the NLQ was subsequently tested for test-retest reliability on a new group of patients from the Nottingham stroke register who were asked to complete it twice. The new NLQ and other measures were sent to patients in a multicentre rehabilitation trial (TOTAL) six and twelve months after recruitment for postal completion. Subjects: One hundred and thirty-seven consecutive patients from the Nottingham stroke register and 466 patients with a stroke in a multicentre rehabilitation trial. Results: The original NLQ was reduced from 37 to 30 items and from five to three response categories. Data from an earlier study were reanalysed and differences between treatment groups remained. The results of a test-retest analysis using kappa showed that six items had excellent agreement, 15 good and nine fair, suggesting acceptable test-retest reliability. Results from the rehabilitation trial showed that the subjects performed all items and few additional activities were suggested. Higher NLQ scores were associated with higher subscores on the Nottingham Extended Activities of Daily Living Scale (NEADL) and lower NLQ scores with living alone and worse emotional health. Conclusion: The NLQ has been successfully modified for postal self-administration but there is potential for further development.
