Support has been found to be related to perinatal health, resulting in the development of the Postpartum Support Questionnaire based on the four categories of support (informational, material, emotional and comparison) identified by House (1981) and Cronenwett (1985). Data from four studies (N = 207) provided evidence of the psychometric properties of the instrument. Internal consistency reliability was demonstrated (alpha = .90 to .94 for total instrument). Test-retest reliability ranged from .69 to .79 for total scores and .30 to .79 for for categories of support. Measures of concurrent validity with the Personal Resource Questionnaire .85 were .42 and .48 at 6 and 8 weeks postpartum. Confirmatory factor analysis using LISREL 7 supported the four categories of support, but the use of these factors separately remains to be demonstrated.
