Discriminant Validity
Chronic SCI:
(Latimer 2006)
- Investigated “extreme group” comparisons to determine if PARA-SCI could show a difference between individuals with SCI who have different levels of physical activity.
- Demographics – age, sex, employment status
- Disability- lesion level, complete/incomplete, means of mobility
- Behavioral characteristics – gym membership, team, participation frequency as high or low
- Significant results only in the following categories:
o Leisure Time Activity- younger subjects participated in greater amounts of moderate intensity activity than older individuals
- total activity was greater in men and younger individuals compared to women and older participants
- those who belong to a gym or team reported more moderate and heavy intensity as well as more total activity
- Lifestyle Activity
- Going to school or working showed greater mild intensity than not
- Cumulative
- Greater heavy intensity in those who belong to a gym or team
