*The maximum number of allowable omissions are for the DSM Symptom Scales and does not apply to Symptom Counts.
** For the Conners 4 Teacher ADHD Index and Self-Report ADHD Index, the scale cannot be scored if the omitted item is one of the weighted items
(see chapter 12 for a discussion of the Conners 4–ADHD Index scoring).

Table A.2. Negative Impression Index Interpreted with Omitted Items: Conners 4 Parent Examples
|
Example |
NII Raw Score |
Number of |
NII Cut-Off |
NII Status |
Explanation |
|
1 |
9 |
1 |
≥ 8 |
An unrealistic or exaggerated presentation |
The NII cut-off (8) has been exceeded by the NII raw score (9), regardless of the omitted items. This NII score may be an underestimate. |
|
2 |
0 |
2 |
≥ 8 |
No indication of exaggerated responding |
The cut-off (8) cannot be met or exceeded. That is, even if both of the omitted items were rated as 3, the score (2 × 3 = 6) does not meet the cut-off. |
|
3 |
5 |
1 |
≥ 8 |
Cannot be determined |
Depending on the value for the omitted item, the cut-off could either be met (e.g., if the omitted item score = 3, the Raw Score = 5 + 3 = 8), or not met (e.g., if the omitted item score = 2, the Raw Score = 5 + 2 = 7). Because of this ambiguity, the NII cannot be interpreted. |
Note. NII = Negative Impression Index. NII Raw Score is based on the sum of the items that were rated.

IncX Raw Score |
Number of |
IncX Cut-Off |
IncX Status |
Explanation |
|
1 |
5 |
1 |
≥ 4 |
A high level of Inconsistency |
The IncX cut-off (4) has been exceeded by the IncX raw score (5), regardless of the omitted items. This IncX score may be an underestimate. |
|
2 |
0 |
1 |
≥ 4 |
No indication of inconsistent responding |
The cut-off (4) cannot be met or exceeded. That is, even if the difference between the omitted pair was 3, the score does not meet the cut-off. |
|
3 |
1 |
1 |
≥ 4 |
Cannot be determined |
Depending on the value for the omitted item, the cut-off could either be met (e.g., if the omitted pair difference score = 3, the Raw Score = 1 + 3 = 4), or not met (e.g., if the omitted pair difference score = 0, the Raw Score = 1 + 0 = 1). Because of this ambiguity, the IncX cannot be interpreted. |
Note. IncX = Inconsistency Index. IncX Raw Score is based on the item pairs that were rated.
