Cross-validiation of the Neuropsychology Behavior and Affect Profile in stroke patients

Internal stability and discriminant validity of the Neuropsychology Behavior and Affect Profile (L. Nelson et al., 1989) were examined in samples of 70 stroke patients and 88 elderly controls. The test is designed to yield indices of premorbid (before-item subset) and present (now-item subset) levels of emotional functioning in each of five scales. With coefficient alphas ranging from.76 to .87, results indicated moderate to high internal stability. The test was also able to reliably distinguish between the criterion stroke sample (n = 42) and a matched group of elderly controls in terms of present levels of emotional functioning (2 weeks poststroke). When discriminant validity was examined in terms of premorbid emotional status (before-item subset), group differences were unexpectedly obtained
