Conners CATA Continuous Auditory Test of Attention

The Conners Continuous Auditory Test of Attention® (Conners CATA®) measures a respondent’s performance in areas of inattentiveness, impulsivity, and sustained attention, making it a useful tool in evaluating attention disorders and neurological functioning. The Conners CATA provides objective information about an individual’s performance in attention tasks, complementing information obtained from rating scales such as the Conners 3.
For a more in-depth assessment of attention, the Conners CATA can also be used in conjunction with the Conners Continuous Performance Test Third Edition™ (Conners CPT 3™), which is a task-oriented computerized assessment of attention-related problems in individuals aged eight years and older. The Conners CATA and Conners CPT 3 can be purchased as a combo kit or individually. Click here to learn more about the Conners CPT 3.

Assessment Reports
provide detailed information about scores from a single administration, presented both numerically and
graphically. An individual's scores are compared to those in the normative sample and elevations at the scale and subscale level are indicated.
Progress Reports 
compare the results of two to four administrations for the same individual to measure changes over time.
These reports are ideal to use when monitoring treatment and intervention effectiveness.

How To Use:​
During the 14-minute, 200-trial administration, respondents are presented with high-tone sounds that are either preceded by a low-tone warning sound (warned trials) or played alone (unwarned trials). Respondents are instructed to respond only to high-tone sounds on warned trials and to ignore those on unwarned trials. On most trials, the low-tone and the high-tone sounds are played in the same ear (non-switch trials). On switch trials, the low-tone warning sound and the high-tone target sound are played in different
ears, requiring the respondent to shift auditory attention from one ear to the other.

Reliability and validity
Users can be confident that the Conners CATA will yield consistent and stable scores across administrations.
Internal Consistency
One measure of a test's internal consistency is split-half reliability, which has been previously used to establish the reliability of other continuous performance tests. Split-half reliability estimates of the Conners CATA scales were calculated for the normative and clinical samples. Results were very strong; across all scores, the median split-half reliability estimate was .95 for the norm and clinical samples (all correlations were significant, p < .001). These results indicate that the Conners CATA demonstrates excellent internal consistency for both the normative and clinical groups.
Test-Retest Reliability
Test-retest reliability refers to the consistency of scores obtained from the same respondent on separate occasions over a specified period of time. To estimate the test-retest reliability of the Conners CATA, a sample of 69 respondents from the general population completed the Conners CATA twice with a 1- to 4-week interval between administrations. The median test-retest correlation was .64. These results suggest a good level of test-retest reliability.
Users can be assured that the Conners CATA will help detect attention deficits and differentiate clinical from non-clinical cases.
Discriminative Validity
Discriminative validity pertains to an instrument's ability
to distinguish between relevant participant groups (i.e., the test's ability to differentiate between clinical and non-clinical groups). In order to conduct discriminative validity analyses, Conners CATA data were collected during the standardization process from 193 children and adults who had an
existing ADHD diagnosis. Conners CATA scores from this
ADHD sample were compared to a matched sample from
the general population. Results indicated that differences were found between the ADHD sample and the matched
general population sample on most measures with small
to moderate sizes (d = 0.10 to 0.63). As expected, the ADHD sample demonstrated poorer performance (i.e., they had higher scores on the Conners CATA). In particular, the ADHD sample had lower d scores, indicating that they had more difficulty in distinguishing between target trials and non-target trials than did the general population sample. Similarly, the ADHD sample made a greater number of errors (i.e., they had higher percentages of Commissions and Perseverative Commissions than did the general population sample) and showed more variability in their responses (i.e., higher HRT SD scores compared to the matched general
population sample).
Incremental Validity
Another approach in establishing the Conners CATA's validity is to show how it works together with other measures of similar constructs in the assessment of attention problems. To assess this, samples were collected in which cases were scored on the Conners CATA and other measures of attention. Specifically, in a sample of 112 youth, Parent reports
on the Conners 3rd Edition (Conners 3-P) were collected
in addition to their scores on the Conners CATA and the
Conners CPT 3. Logistic regressions were conducted in
order to determine how well scales from the Conners CATA improve the diagnostic efficacy of the Conners 3-P and
Conners CPT 3 in predicting group membership into ADHD or general population groups. When the Conners 3-P, Conners CPT 3, and Conners CATA scores were considered together,there was an overall correct classification rate (i.e.,
the ability to accurately predict group membership) of 93.8%, sensitivity (i.e., the ability to correctly detect ADHD
cases) of 94.7%, and specificity (i.e., the ability to correctly detect general population cases) of 92.7%. These values
were 9.9%, 8.7%, and 10.9%, higher respectively than when
the ratingscale was used on its own. Furthermore, the Conners CATA added increased classification accuracy over
and above the Conners 3-P and Conners CPT 3.

Normative Data
The normative sample consists of 1,080 cases and is representative of the United States (U.S.) population in terms of
key demographic variables such as gender, race, geographical region, and parental education level.

在 14 分鐘、200 次試驗管理期間,向受訪者呈現高音聲音,然後是低音警告音(警告試驗)或單獨播放(未警告試驗)。指示受訪者在警告試驗中只對高音作出反應,而在未警告試驗中忽略那些。在大多數試驗中,低音和高音在同一隻耳朵中播放(非切換試驗)。在切換試驗中,低音警告聲和高音目標聲音在不同的耳朵中播放,要求受訪者將聽覺注意力從一隻耳朵轉移到另一隻耳朵。
用戶可以確信 Conners CATA 將在各個管理部門中產生一致且穩定的分數。
​​​​​測試內部一致性的一種衡量標準是對半信度,它以前已用於確定其他連續性能測試的信度。計算了標準和臨床樣本的 Conners CATA 量表的半信度估計值。結果非常好;在所有分數中,正常樣本和臨床樣本的中位分半信度估計值為 0.95(所有相關性均顯著,p < .001)。這些結果表明,Conners CATA 對規範組和臨床組都表現出極好的內部一致性。
重測信度是指同一受訪者在特定時間段內在不同場合獲得的分數的一致性。為了估計 Conners CATA 的重測信度,來自普通人群的 69 名受訪者樣本完成了 Conners CATA 兩次,兩次給藥之間的間隔為 1 至 4 週。中位重測相關性為 0.64。這些結果表明了良好的重測信度水平。
用戶可以放心,Conners CATA 將有助於檢測注意力缺陷並區分臨床病例和非臨床病例。
​​​​​區分效度與工具區分相關參與者群體的能力有關(即,測試區分臨床和非臨床群體的能力)。為了進行區分有效性分析,Conners CATA 數據在標準化過程中從 193 名患有 ADHD 診斷的兒童和成人中收集。來自這個 ADHD 樣本的 Conners CATA 分數與來自普通人群的匹配樣本進行了比較。結果表明,ADHD 樣本和匹配的一般人群樣本在大多數小到中等大小的測量值上存在差異(d = 0.10 到 0.63)。正如預期的那樣,ADHD 樣本表現出較差的表現(即,他們在 Conners CATA 上得分較高)。特別是, d 分數,表明他們比一般人群樣本更難區分目標試驗和非目標試驗。同樣,ADHD 樣本犯了更多的錯誤(即,他們比一般人群樣本具有更高百分比的佣金和持久性佣金)並且在他們的反應中表現出更大的可變性(即,與匹配的一般人群相比,更高的 HRT SD 分數樣本)。
建立 Conners CATA 有效性的另一種方法是顯示它如何與其他類似結構的測量一起工作以評估注意力問題。為了評估這一點,我們收集了樣本,其中的案例在 Conners CATA 和其他注意力措施上進行了評分。具體來說,在 112 名青少年的樣本中,除了他們在 Conners CATA 和 Conners CPT 3 上的分數外,還收集了關於 Conners 第 3 版 (Conners 3-P) 的家長報告。進行邏輯回歸以確定量表的好壞Conners CATA 提高了 Conners 3-P 和 Conners CPT 3 在預測 ADHD 或一般人群群體成員資格方面的診斷功效。當 Conners 3-P、Conners CPT 3 和 Conners CATA 分數一起考慮時,有一個總體正確分類率(即,準確預測群體成員的能力)為 93.8%,敏感性(即正確檢測 ADHD 病例的能力)為 94.7%,特異性(即正確檢測一般人群病例的能力)為 92.7%。這些值分別比單獨使用評分量表時高 9.9%、8.7% 和 10.9%。此外,Conners CATA 在 Conners 3-P 和 Conners CPT 3 之上增加了更高的分類準確度。

規範樣本由 1,080 個案例組成,在性別、種族、地理區域和父母教育水平等關鍵人口變量方面代表了美國 (US) 人口。
