# of studies reporting psychometric properties: 2
Interpretability
- Higher total scores are intended to indicate better performance of behaviours which promote health in individuals with SCI.
- The scores could be used for each sub-scale or as a tool for general overall health.
- There are no norms or reported cut scores for the SCI population.
- Published data for the SCI population is available for comparison (see Interpretability section in the Study Details sheet).
MCID: not established in SCI
SEM: not established in SCI
MDC: not established in SCI
Reliability
Internal consistency is high for the total SCILS (Cronbach’s a = 0.75 – 0.81) and low to high for the SCILS subscales (Cronbach’s a = 0.31-0.86).
(Pruitt et al. 1998; Shabany et al. 2018)
Validity
- SCILS was tested against instruments measuring constructs other than that of the SCILS; correlations of the SCILS are low and non-significant for the following instruments as expected:
- Functional Independence Measure (Pearson’s r = -0.06).
- Brief Symptom Inventory (Pearson’s r = -0.16- -0.13).
- Impact of Event Scale (Pearson’s r = -0.16).
- Beck Depression Inventory (Pearson’s r = -0.17).
- SCILS was tested against instruments measuring the same construct as that of the SCILS; correlations of the SCILS were moderate with:
- Self-assessment of overall health behaviour (Pearson’s r = 0.51) (P<0.005).
- Physician assistant’s assessment of overall health behaviours (Pearson’s r = 0.41) (P<0.005).
- SCILS was tested against instruments measuring the same construct as that of the SCILS; correlations of the SCILS were low with:
- Physical therapist’s assessment of overall health behaviour (Pearson’s r = 0.30) (non-significant).
- Nurse’s assessment of overall health behaviour (Pearson’s r = -0.18).
- SCILS was tested against instruments measuring the same construct as that of the SCILS; correlations of the SCILS were high with:
- Health Behaviour Questionnaire (HBQ) (Pearson’s r = 0.65).

Responsiveness
No values were reported for the responsiveness of the SCILS for the SCI population.
Floor/Ceiling Effect
No values were reported for the presence of floor/ceiling effects in the SCILS for the SCI population.
