What Is the SDQ PDF?
The SDQ PDF is a portable, printable version of the Strengths and Difficulties Questionnaire (SDQ), a brief behavioral screening tool for children and adolescents aged 2‑17. Developed by psychologists Robert Goodman and colleagues, the SDQ assesses emotional symptoms, conduct problems, hyperactivity/inattention, peer relationship difficulties, and prosocial behavior. The PDF format lets clinicians, teachers, and parents administer the questionnaire offline, then score and interpret results using standardized guidelines.

Key Components of the SDQ
The SDQ consists of 25 statements divided into five sub‑scales, each containing five items. Respondents rate each item as "Not True," "Somewhat True," or "Certainly True" (scored 0‑2). A total difficulties score (sum of the first four sub‑scales) ranges from 0‑40, while a separate prosocial score ranges from 0‑10.
Sub‑scale breakdown
- Emotional Symptoms (e.g., worries, nervousness)
- Conduct Problems (e.g., temper, rule‑breaking)
- Hyperactivity/Inattention (e.g., restlessness, concentration)
- Peer Relationship Problems (e.g., loneliness, being bullied)
- Prosocial Behavior (e.g., helpfulness, empathy)
How to Download and Use the SDQ PDF
Official SDQ PDFs are hosted by the SDQ website. Choose the version that matches your respondent group:
- Parent‑report form
- Teacher‑report form
- Self‑report form (ages 11‑17)
After downloading, print the 8‑page document. Each page includes the questionnaire, scoring tables, and interpretation guidance. No special software is required; the PDF is compatible with all major readers.
Scoring the SDQ PDF
Scoring follows three steps:
Interpretation uses normative cut‑offs (normal, borderline, abnormal) that differ by age and informant. Below is a concise reference table.
| Score Type | Normal Range | Borderline | Abnormal |
|---|---|---|---|
| Total Difficulties (0‑40) | 0‑13 | 14‑16 | 17‑40 |
| Prosocial (0‑10) | 6‑10 | 5 | 0‑4 |
Interpreting Results
High total difficulties scores suggest the need for further assessment or intervention. Specific sub‑scale elevations point to particular concerns (e.g., high hyperactivity indicates attention‑related issues). Prosocial scores provide a protective context; low scores may signal social skill deficits.
Clinicians typically combine SDQ results with clinical interviews, observations, and other measures before diagnosing a disorder.
Common Uses of the SDQ PDF
The SDQ is employed in a variety of settings:
- Schools: Screening large student bodies for mental‑health needs.
- Primary care: Quick check‑ups during pediatric visits.
- Research: Standardized data collection across studies.
- Community programs: Monitoring outcomes of youth interventions.
Advantages and Limitations
Advantages
- Brief (5‑10 minutes to complete).
- Validated in over 80 languages and cultures.
- Free to use for non‑commercial purposes.
- PDF format ensures offline accessibility.
Limitations
- Self‑report form may be less reliable for younger children.
- Does not replace a full diagnostic interview.
- Cut‑offs are population‑specific; local norms may be needed.
Frequently Asked Questions
Can I use the SDQ PDF for clinical diagnosis?
No. The SDQ is a screening tool, not a diagnostic instrument. Scores should trigger further evaluation by qualified professionals.
Is the SDQ PDF available in other languages?
Yes. The SDQ website offers translated PDFs for more than 80 languages, each with culturally adapted norms where available.
How often should the SDQ be administered?
For monitoring purposes, many services repeat the questionnaire every 6‑12 months, or after a major intervention.
Do I need permission to distribute the PDF?
The SDQ is free for non‑commercial use. Commercial users must obtain a license from the developers.
Where to Find Reliable SDQ PDFs
The safest source is the official SDQ portal (sdqinfo.org). Third‑party sites may host outdated versions or incomplete scoring tables.
Conclusion
The SDQ PDF remains one of the most practical, evidence‑based tools for early identification of emotional and behavioral difficulties in youth. By downloading the correct form, scoring accurately, and interpreting results within a broader clinical context, practitioners can efficiently flag concerns and guide timely support.
