This study evaluated the impact of a cognitive retraining intervention designed to enhance the attention skills of schizophrenia patients. The dependent variables included measures of perceptual sensitivity and sustained vigilance derived from a visual continuous performance test, as well as visual span of apprehension and world-list recall. Sixteen subjects received approximately 15 hours of repeated practice with computer-mediated vigilance tasks. Seventeen subjects were assigned to a no-treatment control group. All subjects were rated on measures of negative and positive symptoms before treatment. Despite improved performance on the training tasks, no significant changes on the outcome measures were observed following treatment. Thus, it is suggested that cognitive rehabilitation interventions with schizophrenia patients stress the teaching of behavioral strategies that bypass deficits, rather than remediating deficiencies in basic abilities, such as attention.
本研究评估了一项旨在提高精神分裂症患者注意力技能的认知再训练干预措施的效果。因变量包括从视觉持续操作测试得出的感知敏感性和持续警觉性指标，以及视觉领会广度和单词表回忆。16名受试者接受了约15小时的计算机介导警觉任务重复训练。17名受试者被分配到无治疗对照组。所有受试者在治疗前均接受了阴性和阳性症状指标的评定。尽管训练任务表现有所改善，但治疗后在结果指标上未观察到显著变化。因此，建议对精神分裂症患者进行的认知康复干预应强调传授绕过缺陷的行为策略，而非纠正诸如注意力等基本能力的不足。
