Adjusted prevalence ratios (aPR) for Tourette syndrome and co-occurring mental, emotional and behavioral (MEB) conditions predicting the parenting aggravation index score controlling for each other and demographic variables, National Survey of Children’s Health 2007
| Conditions included in separate models predicting parenting aggravation index |
Tourette syndrome aPR (CI) |
Co-occurring MEB condition aPR (CI) |
|---|---|---|
| Model including Tourette syndrome, but not MEBs as independent variables (original aPR) |
3.8 (2.2–6.6) | |
| Model including Tourette syndrome plus: | ||
| Any MEBa | 1.7 (0.9–3.2)b | 5.2 (4.5–6.1) |
| Any externalizing condition | 1.7 (0.9–3.1)b | 5.5 (4.8–6.4) |
| Attention-deficit/hyperactivity disorder | 1.9 (1.0–3.6)b | 4.4 (3.8–5.1) |
| Behavioral or conduct problems | 1.5 (0.8–2.9)b | 7.6 (6.5–8.8) |
| Any internalizing condition | 1.9 (1.0–3.6)b | 4.3 (3.7–5.1) |
| Depression | 2.2 (1.1–4.2)b | 4.4 (3.6–5.3) |
| Anxiety | 2.3 (1.0–5.3)b | 3.9 (3.3–4.6) |
| Autism spectrum disorder | 2.4 (1.4–4.0) | 4.7 (3.6–6.1) |
Note: Each row represents a separate model; PR adjusted for age, sex, race, ethnicity (95% CI); CI = Confidence Interval.
a
Mental, emotional or behavioral problems include attention-deficit/ hyperactivity disorder, behavioral or conduct problems, depression, anxiety and autism spectrum disorders.
b
Relative standard error (RSE) > 30% (Range = 32–44%); RSEs for aPRs are reported if over 30% because these estimates may not be reliable.
