What a Conners-4 Interpretation Should Say

You have three Conners-4 forms in front of you. Mom's parent form is elevated across the board; the teacher form is flat except for Inattention; and the self-report from your 14-year-old says he's basically fine. It's Thursday, the report is due Monday, and the section you're stuck on is the Conners-4 interpretation, not the scoring.

Here's the practical problem. Most reports handle this by listing T-scores in a paragraph and calling it interpretation. That isn't interpretation; that's transcription with better grammar. A Conners-4 interpretation that actually holds up tells the reader what the scores mean for this kid, why the raters disagree, and what you're not willing to conclude from a rating scale alone.
‍

Start with response style, not the elevations

Before you write a single sentence about Inattention, you check the validity indices. Negative Impression, Positive Impression, Inconsistency Index, Omitted Items. If a parent form has an elevated Negative Impression score, everything downstream is qualified, and your report should say so in the interpretation, not bury it in a table appendix nobody reads.

The Conners 4 manual's interpretation chapter walks through this in order for a reason: response style analysis comes before you interpret content, because an inconsistent or negatively skewed protocol changes what the elevations are allowed to mean.

What that looks like in a report:

"Mrs. R's ratings produced an elevated Negative Impression score, which can occur when a caregiver is describing a period of acute difficulty or is seeking services. Her ratings are reported below and are broadly consistent with teacher observations, but the magnitude of elevation should be interpreted with some caution."

That's honest, and it's defensible. It also protects you when someone re-evaluates this kid in two years, and the numbers look different.

What do the T-scores actually mean here?

Plain version, and you know this, but the report reader may not: T-scores have a mean of 50 and a standard deviation of 10. Above 60 is where you start paying attention; 70 and up is very elevated. The MHS scores chapter makes it clear that these ranges are guidelines that require clinical training and judgment and shouldn't be applied automatically. Which is the whole ballgame, honestly. A T-score of 68 on Inattention in a bright eighth grader who just moved schools is a different clinical object than a 68 in a kid with a three-year paper trail of the same complaint.

Two things worth writing into your Conners-4 interpretation that a lot of reports skip:

The measurement error. Every score has a confidence interval. If parent Inattention is 72 and teacher Inattention is 66, those may not be meaningfully different. Say that instead of narrating a discrepancy that isn't there.

Percentiles for the non-clinical reader. Parents and school teams understand "higher than about 95% of boys his age" better than they understand T = 65. Put both. It costs you four words.

[KEY TAKEAWAY: A number in a table is data. A number with a comparison group, a confidence band, and a "so what" is interpretation.]
‍

Why do parents and teachers rate so differently on the Conners-4?

This is the question people actually search, and it's the section most reports handle badly by pretending the discrepancy is a problem to be resolved. It usually isn't. It's information.

Setting demands differ. A classroom pulls sustained attention for 45-minute blocks with limited movement. A Saturday at home does not. Teachers compare a child to 28 same-age peers all day; parents compare to siblings and to their own childhood. Neither rater is wrong; they're reporting from different vantage points with different reference groups.

The Conners 4 manual addresses statistical significance between raters directly, so you're not left eyeballing it. Use that. But write the interpretation in behavioral language:

"Ratings across home and school converged on inattention and disorganization, and diverged on hyperactivity, which was reported as significantly elevated by his mother and within typical limits by his classroom teacher. This pattern is common and may reflect the greater structure and adult monitoring available in the classroom setting, as well as differences in what each rater has the opportunity to observe."

The same principle applies when you're triangulating with other measures. If you're also running a BASC-3 and the informant patterns split there too, that's worth a sentence, not a shrug. (see Informant Discrepancy Interpretation Guide for BASC-3)

The DSM symptom scales, content scales, and where the ADHD Index fits

These do different jobs, and your report should treat them differently.

The DSM symptom scales map to criteria. They're the ones you'll reference when you get to your diagnostic formulation, and they're the ones a reviewing clinician will look at first. Report them with the symptom counts where relevant, because "six of nine inattentive symptoms endorsed at a clinically significant level by both raters" carries more weight in a formulation than a T-score alone.

The content scales (Inattention/Executive Dysfunction, Hyperactivity, Impulsivity, Emotional Dysregulation, Depressed Mood, Anxious Thoughts) are where you get the clinical texture. Emotional Dysregulation elevated alongside Impulsivity tells a different intervention story than Inattention alone. Depressed Mood and Anxious Thoughts elevations are your comorbidity screening flags, and they should be routed somewhere in your recommendations rather than sitting in the table doing nothing.

The ADHD Index is probability-based, which trips people up. It's not a severity score. The Conners 4 sample report from Pearson shows how the probability score gets presented to a parent audience, and it's a useful model for phrasing. In your interpretation, keep it what it is: an actuarial estimate of similarity to a clinical ADHD sample, not a diagnosis and not a substitute for your history-taking.

And critical items. If the self-report flagged an item about self-harm or if the Severe Conduct scale is elevated, that goes in the body of the report and in your recommendations, not just in the scoring printout. I've seen reports in which a flagged item appeared only in the appendix. Don't do that.

Impairment is the part that makes it a diagnosis

A kid can have elevations on every Conners-4 scale and still not meet the criteria because the criteria require impairment across settings. The Impairment and Functional Outcome items exist for this, and they're routinely underused in reports.

So write it. Grades, homework completion time, peer relationships, whether he's lost privileges or been removed from class, whether the family fights about homework four nights a week. That's what impairment sounds like in a report. Not "significant functional impairment was noted."

This is also where you hedge appropriately. Rating scales are informant report. They're not observation; they're not performance data, and the MHS product materials frame Conners 4 results as guiding decision-making, not making it. Your Conners-4 interpretation should be a single converging line of evidence alongside developmental history, record review, observation, and any cognitive and academic testing you administered. Say that explicitly in the report. Reviewers notice when you don't. (see Psychological Reports: What Makes Them Defensible)

Putting it together without losing your Sunday

The honest problem with all of this is that the interpretation I just described takes maybe 25 minutes of actual clinical thinking and then another 90 minutes of typing it into a structure, cross-checking every T-score against the printout, and making sure the recommendations line up with the elevations you flagged in the body. The thinking part is the job. The rest is data entry with a doctorate.

This is where Psynth earned its place in my workflow; it takes the scores and the informant data and produces a first draft with the interpretive narrative already organized and grounded in the actual numbers, so I'm editing clinical judgment instead of retyping T-scores. Dr. Lexie Molina went from three to four hours per psychoeducational report to about fifteen minutes for a first draft, and she hasn't worked a weekend since. That tracks with what I've seen. The Psynth draft doesn't decide anything; you still make the diagnostic call, and you still own every sentence, but the synthesis grind stops eating your evenings.

The test that separates a good Conners-4 interpretation from a bad one: could a psychologist who has never met this child read your paragraph and understand why you concluded what you concluded? If yes, you're done. If they'd have to go find the score table to follow you, rewrite it.

What to keep on your desk

The short version, if you're editing a report right now: validity first, T-scores with percentiles and confidence, rater differences explained as setting differences rather than errors, DSM scales for the formulation and content scales for the texture, ADHD Index as probability not severity, critical items surfaced in the body, and impairment described in real behavior. Then a clear statement of what the Conners-4 can't tell you on its own.

Most of us know all of that. The reason it doesn't always make it into the report is time, not knowledge. If you'd rather spend that hour on the interpretation than the typing, Psynth drafts the rest from your scores, and the free trial is a low-friction way to run it on a real Conners-4 report and see whether the draft holds up to your standards.
