Measurement Property Summary
Number of studies reporting psychometric properties: 6
Interpretability
- High scores on the Fearful Despondency, Overwhelming Disbelief, and Negative Perceptions of Disability subscales represent greater agreement with the appraisals; respondents with higher scores on these subscales are more likely to appraise their injury in terms of loss and threat and to perceive their injury as unmanageable.
- Low scores on the Determined Resolve, Growth and Resilience, and Personal Agency subscales represent greater agreement with the appraisals (though the range of scores is not provided). Respondents with lower scores on these subscales were more likely to appraise their injury in terms of loss and threat and to perceive their injury as unmanageable.
- No information is given regarding norms or meaningful cut-off scores for the SCI population, although the ADAPSS is still in early stages of development.
- MCID: not established in SCI population
- SEM: not established in SCI population
- MDC: not established in SCI population
Typical Values
Mean scores reported for the ADAPSS-sf have varied from 13.94 to 19.21 (SD = 6.10-7.44)
(Eaton et al. 2018; n=371; 261 males, 110 females; non-traumatic and traumatic; injury level: Cervical-sacral; AIS A-D)
(Mignogna et al. 2014; n=98; 94 males, 4 females; mean (SD) age: 18.3 (13.1) years; tetraplegia (low): n=14, tetraplegia (high, AIS A,B,C): n=6, AIS D: n=41; traumatic injury: yes (77), no (21))
(Dean et al. 2020; n=115; age: 18 years or younger at time of SCI, initially interviewed at age 19 or older, and followed annually)
(McDonald et al. 2018; n=262; 92% males; median age: 59 years; traumatic and non-traumatic SCI; 51% AIS D; paraplegia and tetraplegia)
Reliability – Moderate to High
Number of studies reporting reliability data: 3
- Moderate to High internal consistency for the ADAPSS subscales (Personal Agency): α=0.70
- Moderate to High internal consistency for the ADAPSS subscales (Fearful Despondency): α= 0.85
- Moderate to High test-retest reliability for the ADAPSS subscales: α=0.74-0.86
(Dean & Kennedy 2009; n=237; 162 males, 75 females; mean age = 47 (range: 18-81); tetraplegia: 37%, paraplegia: 56%, unknown: 7%)
Validity – Low to High
Number of studies reporting validity data: 4
- Low correlation between the Perceived Manageability Scale – Needs Assessment Checklist and the following ADAPSS subscales:
- Fearful Despondency: ρ=-.597
- Overwhelming Disbelief: ρ=-.468
- Determined Resolve: ρ=-0.599
- Growth and Resilience: ρ=-.345
- Negative Perceptions of Disability: ρ=-.533
- Personal Agency: ρ=-.519
- High correlation between the Hospital Anxiety and Depression Scale – Anxiety subscale and the ADAPSS Fearful Despondency subscale: ρ=.649 (p<.01)
- Moderate correlation between the Hospital Anxiety and Depression Scale – Anxiety subscale and the ADAPSS subscales:
- Overwhelming Disbelief: ρ=.597 (p<.01)
- Determined Resolve: ρ=.347 (p<.01)
- Negative Perceptions of Disability: ρ=.496 (p<.01)
- Personal Agency: ρ=.393 (p<.01)
- Low correlation between the the Hospital Anxiety and Depression Scale – Anxiety subscale and the ADAPSS Growth and Resilience subscale: ρ=.187 (p<.01)
(Dean & Kennedy 2009; n=237; 162 males, 75 females; mean age = 47 (range: 18-81); tetraplegia: 37%, paraplegia: 56%, unknown: 7%)
- Low significance in correlation between the ADAPPS-sf total score and life satisfaction: (p< .001)
- High significance in correlation between the ADAPPS-sf total score and controlling for depressive symptoms (p<.604)
- Low significance in correlation between the ADAPPS-sf total score and level of injury: (p<.051)
- Ranking N/A: standard constant β values (life satisfaction: -0.72, controlling for depressive symptoms: 0.05, level of injury: 0.153) have not been ranked due to lack of established criteria
(Mignogna et al. 2014; n=98; 94 males, 4 females; mean (SD) age: 18.3 (13.1) years; tetraplegia (low): n=14, tetraplegia (high, AIS A,B,C): n=6, AIS D: n=41; traumatic injury: yes (77), no (21))
Responsiveness
No values were reported for the responsiveness of the ADAPSS for the SCI population.
Floor/Ceiling Effect
No values were reported for the presence of floor/ceiling effects in the ADAPSS for the SCI population.
