- Abstract
The Pediatric psychoSocial Risk Index (PSRI) is psychosocial risk screening instrument for health practitioners. The objective of this study was to confirm validity evidence of a truncated version of PSRI.PSRI was completed initially by 100 parents of children aged 0 to 18 years admitted to a tertiary hospital; 50 parents repeated the PSRI 3 days later. Analysis includes principal component analysis (PCA) to include the least number of items that explain the most variance in a shortened version of PSRI as well as confirming test-retest reliability and internal consistency of the shortened instrument.PSRI originally had 86 items, 85 close-ended items were analyzed. Three items were excluded because of missing test-retest data. Item reduction resulted in truncation of 16 items; 66 items remained. A Kaiser-Mayer-Orkin test of sampling adequacy resulted in reduction of 14 items; 52 items remained. Initial PCA led to reduction of 26 items. The PCA was rerun on remaining items, resulting in reduction of 6 further items; 18 items remained. Two items with >10% missingness were removed leaving 16 items in the final PSRI. Test-retest reliability was 0.98 and mean within-person across-item reliability was 0.95. Cronbach α was 0.9. Remaining items represented 9 social risk themes: food insecurity, medical complexity, home environment, behavioral issues, financial insecurity, parenting confidence, parental mental health, social support, and unmet medical needs.PSRI was reduced from 86 to 16 items with high internal consistency and reliability. PSRI demonstrates adequate validity supporting practitioners to screen families about their psychosocial risk.
