The purpose of this study was to explore the effectiveness of
informational portrait vignettes for enhancing physical activity-related
psychosocial cognitions in adults with spinal cord injury (n = 90). METHODS:
Using the Health Action Process Approach (HAPA), participants were classified as
being in the motivational or volitional phase of behavior change. Half of the
participants were randomly allocated to read an experimental vignette, which
described the physical activity behaviours, thoughts, and feelings of a character
demographically similar to the reader. The remainder read a control vignette.
Social cognitions were measured one-week before, and immediately after reading
the vignette. RESULTS: Analyses revealed no significant effects of the vignettes
on social cognitions (p > 0.05). CONCLUSIONS: Informational portrait vignettes
describing a physically active person with SCI and targeting multiple HAPA-based
social cognitions are not recommended as a physical activity promotional strategy
for people with SCI. The effectiveness of other types of vignettes should be
examined. IMPLICATIONS FOR REHABILITATION: Until further research is completed to
determine whether social comparison strategies play a meditational role in
accounting for the impact of a tailored informational portrait vignette to alter
leisure time physical activity among those with spinal cord injury, these types
of informational intervention should not be utilized in a rehabilitation, or
real-world, setting. Although informational portrait vignettes may not be
effective in altering leisure time physical activity social cognitions among
those with spinal cord injury, different types of vignettes, such as composite
vignettes, should be explored.
