Validity and Reliability Testing of the Prenatal Psychosocial Profile

Two studies of low-income pregnant women (N = 179) were done to examine the validity and reliability of the Prenatal Psychosocial Profile (PPP). The PPP, a composite of the Rosenberg Self-Esteem Scale, the Support Behaviors Inventory, and a newly developed measure of stress, is a brief, comprehensive clinical assessment of psychosocial risk during pregnancy. Construct validity of the stress scale was supported by theoretically predicted negative correlations with self-esteem, partner support, and support from others (N = 91). Convergent validity of the stress scale was demonstrated by a correlation of .71 with the Difficult Life Circumstances Scale. Adequate levels of internal consistency were found. Interrelationships between the four subscales were consistent with the underlying conceptualization, and there was beginning evidence of the factorial independence of the subscales.
