本研究探討羅夫2 與7 選擇性注意力測驗於40 名診斷為精神分裂症的門診病患之效度。當損傷標準被定義為低於常模平均數的 1 個標準差時，65-78% 的病人在速度分數上達到損傷標準，相對的只有23-28% 病人在正確分數上達到損傷標準。病人在自動偵測的測驗情境所表現的速度與正確度皆優於在控制搜索情境。女性在與目標類似的干擾刺激背景中 (控制搜索情境)，其目標刺激搜尋的速度快於男性。年齡與教育程度和羅夫2 與7 選擇性注意力測驗的各項分數並無顯著相關。速度與正確分數和作業智商有顯著正相關。速度分數與負性症狀呈現負相關，而正確分數與精神症狀之間並無顯著關係。這些初步結果顯示2 與7 選擇性注意力測驗能有效的使用於門診精神分裂症患者的選擇性注意力之評量。

This study validated the use of the Ruff 2 & 7 Selective Attention Test in 40 outpatients with schizophrenia. Sixty-five to seventy-eight percent of the patients were impaired (defined as being more than one standard deviation below the normative mean) on measures of speed, but only 23.0-28.0% scored in the impaired range for accuracy. Patients were faster and more accurate in automatic detection rather than controlled search conditions. Females were significantly faster than males in visual search when the target discriminability was low. Age and education were not correlated with any of the 2 & 7 Test scores. There were significant positive associations between speed and accuracy measures and performance IQ. Speed scores were inversely related to negative symptoms, while
accuracy had no correlation with symptom scores. These preliminary results
demonstrate that the 2 & 7 Test is a valid instrument for assessing selective attention in outpatients with schizophrenia.
