Understanding Extreme Injustice Appraisal Phenotypes in Newly Acquired Spinal Cord Injury.

Area of Science:

• Psychology
• Rehabilitation Medicine
• Clinical Research

Background:

• Spinal cord injury (SCI) can lead to significant psychosocial challenges, including appraisals of injustice.
• Understanding extreme phenotypes of these appraisals is crucial for developing effective interventions.

Purpose of the Study:

• To identify and characterize extreme phenotypes of injustice appraisals in individuals with recent SCI.
• To inform psychosocial interventions and future clinical research for SCI populations.

Main Methods:

• Cross-sectional analysis of baseline data from 101 adults with recent SCI.
• Used the Injustice Experience Questionnaire (IEQ) to classify participants into low (IEQ ≤ 12) and high (IEQ ≥ 26) injustice appraisal groups.
• Assessed depressive symptoms (PHQ-8), PTSD symptoms (PCL-5), anger (STAXI-II), disability appraisals (ADAPSS), and quality of life (SCI QOL BDS).

Main Results:

• High injustice appraisal phenotype exhibited significantly higher depressive symptoms (p<.001), PTSD symptoms (p<.001), and anger (p<.001) compared to the low appraisal group.
• Maladaptive appraisals of disability were significantly higher (p<.001) in the high injustice group.
• Lower quality of life satisfaction was reported across all domains (p<.01) in individuals with high injustice appraisals, with large effect sizes.

Conclusions:

• Extreme phenotyping reveals distinct psychosocial profiles in individuals with SCI based on injustice appraisals.
• High injustice appraisals are strongly linked to increased psychological distress and diminished quality of life.
• Findings underscore the necessity for interventions targeting perceptions of unfairness in early SCI rehabilitation to enhance psychological outcomes.
