*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 Omitted Items	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.

Table A.3. Inconsistency Index Interpreted with Omitted Items: Conners 4 Parent Examples

Example	IncX Raw Score	Number of Omitted Item Pairs	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.

Table A.4. DSM ADHD Inattentive Symptoms Scale Interpreted with Omitted Items: Conners 4 Parent Examples

Example	DSM ADHD Inattentive Symptoms Obtained Score	Number of Omitted Items	Symptom Count Reported	Meaning of Notation
1	1	1	1*/9	*Symptom Count(s) may be underestimated due to omitted item(s).
2	1	2	?	? = could not be scored due to omitted item(s).
3	8	2	8*/9	*Symptom Count(s) may be underestimated due to omitted item(s).

Note. The DSM requires at least 6/9 symptoms to be endorsed to meet Criterion A of the diagnostic criteria for ADHD for youth ≤ 16 years of age, and at least 5/9 symptoms for youth ≥ 17 years of age.
