The test-retest stability of the Maternal Perinatal Scale (MPS) was examined for a random sample of 41 mothers. The stability of items over a two-day period ranged from 1.00 to .85 (r) for items with an underlying normal distribution and from 1.00 to .86 (Cramer's V or Phi coefficient) for nominal items. Moreover, 90% of the coefficients exceeded .90. Intercorrelations between specific information assessed by the items were consistent with clinical obstetric and research evidence. The results were interpreted as lending support to the clinical and research potential of a systematic self-report format in the assessment of perinatal histories. 相似文献
