Objective[1]

  • Identify persons with activity limitation.
  • Assess the extent of Activity Limitation and the risk of increasing impairment.
  • Target people affected by leprosy, diabetes or other peripheral neuropathies
  • Be applicable world-wide.
  • Be used in combination with “Impairment” and “Participation-Restriction”4 tools in order to measure disablement from a holistic point of view.
  • Provide a means to measure the results of interventions whose goal is to improve function and/or self care.

Intended Population[1]

People affected by

  • Leprosy
  • Diabetes and
  • Other peripheral neuropathies in both low-income and developed areas.

Method of Use[1]

The scale is usually interviewed by the trained personnel. Any literate medical or non-medical worker/volunteer can administer the SALSA Scale. People using the SALSA Scale should have proper training during two days from an experienced, previously trained user. The training should address how to administer the questionnaire, how to calculate the score and how to interpret the results.

Some of the tips are:

1. Clarify the aim of the questionnaire.

2. All questions must be asked.

3. All questions must be asked exactly as is written on the form in Bold

4. Questions are close-ended.

5. It is the respondent’s personal opinion of each activity question that should be

recorded. 

Evidence

Reliability

Internal consistency:

  • correlation coefficients - 0.31 to 0.65
  • Crohnbach’s alpha - 0.70 and 0.90

Test-retest reliability:

  • intra-tester reliability- the 20 items had Kappa’s ranging from 0·51–1; 15 items had Kappa’s > 0·6; 12 items had Kappa’s > 0·7.
  • inter-tester reliability- Kappa’s ranged from 0·45–0·8; 15 items had Kappa’s > 0·6; 8 items had Kappa’s > 0·7[1]

Validity

Construct validity: good [2]

Convergent validity: good

Face validity: established [1]
