Leeds Adult Spasticity Impact Scale (LASIS)

Overview


A literature search was conducted to identify all relevant publications on the psychometric properties of the Leeds Adult Spasticity Impact Scale (LASIS). At the time of publication no studies have reported on the psychometric properties of the LASIS in the stroke population.

Floor/Ceiling Effects

While no studies have investigated the floor or ceiling effects of the LASIS when used with a stroke population, it ca be anticipated that ceiling effects may exist when the LASIS is used with high-functioning patients, due to the hierarchical relationship of items (Ashford et al., 2008).

Reliability

Internal consistency:
No studies have reported on the internal consistency of the LASIS.

Test-retest:
No studies have reported on the test-retest reliability of the LASIS.

Inter-rater:
No studies have reported on the inter-rater reliability of the LASIS.

Intra-rater:
No studies have reported on the intra-rater reliability of the LASIS.

Validity

Content:
No studies have reported on the content validity of the LASIS.

Criterion:
Concurrent:
No studies have reported on the concurrent validity of the LASIS.

Predictive:
No studies have reported on the predictive validity of the LASIS.

Construct:
Convergent/Discriminant:
No studies have reported on the convergent/discriminant validity of the LASIS.

Known Group:
No studies have reported on the known-groups validity of the LASIS.

Responsiveness

No studies have reported on the responsiveness of the LASIS.

Sensitivity/Specificity:
No studies have reported on the sensitivity or the specificity of the LASIS.
