The relationship between presenting psychopathological features and long-term outcome, in an incidence by first admission group of 43 schizophrenic patients from northern Alberta, followed up 14 years later, is examined. The symptoms examined for predictive ability were those on the New Haven Schizophrenia Index. Outcome was assessed on scales reflecting economic, social and psychiatric adjustment, summed for a combined score. Multiple regression analyses of the presenting NHSI symptoms to the outcome measures showed correlations of .60-.66, thus explaining statistically about 40% of the outcome variance.
对来自阿尔伯塔省北部的43名首次入院的精神分裂症患者进行了研究，随访14年后，考察了其首次出现的精神病理学特征与长期预后之间的关系。所检验的具有预测能力的症状是纽黑文精神分裂症指数上的那些症状。通过反映经济、社会和精神适应情况的量表对预后进行评估，并将这些量表得分相加得出综合分数。对首次出现的纽黑文精神分裂症指数症状与预后指标进行的多元回归分析显示，二者的相关性为0.60 - 0.66，因此从统计学角度解释了约40%的预后差异。
