items comprising the Parent Domain are divided into seven subscales: Parent Depression, Parent Attachment, Restrictiveness of Parental Role, Parental Sense of Competence, Social Isolation, Relationship with Spouse, and Parental Health. Finally, the optional Life Stress Domain assesses the number of major changes in the family's environment (e.g., death in the family, job changes). Normative information on the PSI has been gathered on large samples of mothers recruited from a variety of public and private pediatric clinics in the United States (Abidin, 1995). Percentiles, means, and standard deviations are available for the domain scores and the total score by child age. The normative information on fathers' responses to the PSI (n = 200) suggests that fathers earn significantly lower stress scores on all components of the PSI when compared to mothers (Abidin, 1995). The fathers in the normative sample, however, were predominantly Caucasian (95%) and college-educated (48%) and may not be representative of the general population. Internal reliability coefficients for the subscales of the PSI have been determined for both the original standardization sample of 534 parents who obtained services from small group pediatric clinics in central Virginia and from a cross-cultural sample of 435 parents from Bermuda and the United States (Hauenstein, Scarr, & Abidin, 1986). The internal reliability coefficients from both of these samples were fairly consistent. The alpha coefficients for both samples ranged from .59 to .78 for the Child Domain subscales and from .55 to .80 for the Parent Domain subscales. Based on the sample of 534 parents, the internal reliability coefficient was .89 for the Child Domain Total Scale score, .93 for the Parent Domain Scale Total score, and .95 for the Total stress score. Test-retest reliability coefficients have been computed for intervals ranging three weeks, three months, and one
