Johnny case study: DSM-5 Level 1 cross-cutting measure
Score the parent-rated DSM-5 Level 1 Cross-Cutting Symptom Measure for Johnny, use it to separate typical childhood behaviour from clinically significant psychopathology, assign DSM diagnoses in descending order with rationale, explain why other diagnoses were excluded, and decide on referral, in 500-750 words.

What a cross-cutting screener can and cannot establish
The instrument at the centre of this assignment determines how the whole paper should be written. The DSM-5 Level 1 Cross-Cutting Symptom Measure is a screener: it surveys domains such as somatic complaints, sleep, inattention, irritability, anger, anxiety and depression, and a rating at or above the threshold in a domain indicates that further inquiry is warranted, not that a disorder is present. So the honest answer to what information do you gather from this instrument is that it tells you where to look, and the honest answer to what you would do next is that you would follow the flagged domains into a Level 2 measure, a clinical interview and collateral information from school. The measure was also completed by the mother alone, which means you have one informant's view of behaviours that may present differently at school — a limitation worth stating, since cross-informant disagreement is the norm in child assessment rather than the exception.
That constraint makes the diagnostic section a matter of careful hedging rather than confident labelling, and the assignment does ask you to assign diagnoses in descending order with rationale. Do it as diagnostic impressions tied explicitly to DSM-5 criteria: name the criteria Johnny's presentation meets, state what duration and impairment evidence you have and what you lack, and order the impressions by how much of the presentation each accounts for. The rule-out section is graded equally and is where most papers thin out — say what other conditions the flagged domains could represent and what specifically argues against each, including developmentally typical behaviour, which the assignment names as the comparison. Then the referral decision follows naturally from what you could not establish, and it should cite impairment rather than symptom counts, which is also how the DSM itself distinguishes a disorder from a difficulty. Say what Johnny cannot currently do, and what a specialist would establish that you could not.

Review before submission
Common mistakes
- Treating threshold scores on a screener as diagnostic findings.
- Ignoring that a single informant completed the measure.
- Assigning diagnoses without naming the DSM-5 criteria they rest on.
- Writing a thin rule-out section when it carries equal weight.
- Omitting developmentally typical behaviour from the differential.
- Justifying referral by symptom count rather than by impairment and uncertainty.
Submission checklist
- The instrument is described as a screener with its purpose stated.
- Single-informant limitation is acknowledged.
- Diagnoses are ordered and each is tied to criteria.
- Exclusions are explained with what argues against each.
- The referral decision is reasoned from impairment.
- The paper is 500-750 words with five scholarly references beyond the text.
