This study determined the influence of morning and afternoon scheduling on the assessment of communicative skills of aphasic patients. Eight short-term (3 to 9 months post-onset) and eight long-term (12 or more months post-onset) aphasic subjects were administered 11 tests from the Porch Index of Communicative Ability (PICA) at specified times in the morning (A.M.) and afternoon (P.M.). Order of scheduling (A.M. first, P.M. second; P.M. first, A.M. second) was determined randomly but balanced between groups. Results indicated an absence of significant main effects for onset, scheduling, and test order; however, significant interactions between the scheduling and test-order factors were evidenced on the naming and auditory identification tests and on all overall measures. Analyses of these interactions revealed that patients scheduled first in the A.M. decreased their mean scores when assessed a second time in the P.M., whereas those scheduled first in the P.M., increased their scores when seen a second time in the A.M. Findings suggest that aphasic patients can be expected to do better on morning than afternoon assessments regardless of the order in which they are scheduled. Clinically, this indicates a need for consistency in the scheduling of periodic assessments for individual aphasic patients.
本研究确定了上午和下午安排对失语症患者沟通能力评估的影响。对8名短期（发病后3至9个月）和8名长期（发病后12个月或更长时间）失语症受试者，在上午（A.M.）和下午（P.M.）的特定时间进行了11项来自沟通能力波奇指数（PICA）的测试。安排顺序（上午先测，下午后测；下午先测，上午后测）随机确定，但在各小组间保持平衡。结果表明，发病时间、测试安排和测试顺序均无显著主效应；然而，在命名和听觉识别测试以及所有总体测量中，测试安排和测试顺序因素之间存在显著交互作用。对这些交互作用的分析表明，上午先接受测试的患者在下午再次接受评估时平均得分下降，而下午先接受测试的患者在上午再次接受评估时得分增加。研究结果表明，无论安排顺序如何，失语症患者在上午评估中的表现预计会优于下午评估。临床上，这表明对个体失语症患者进行定期评估时，安排需要保持一致。
