Table 1.
Cohort demographics. Estimated means (95% CI) reported for IDACI rank (a measure of socioeconomic status) and SDQ Total difficulties scores, and estimated percentage of males using population weights. Percentages of children in education provision or referred to speech‐language therapy are based on raw counts
| Typically developing | LD‐only | LD‐plus diagnosis | |
|---|---|---|---|
| Percent male | 48.43 (41.76, 55.16) | 55.54 (36.71, 72.90) | 75.80 (56.90, 88.15) |
| IDACI rank scorea | 23,704 (22,731, 24,677) | 15,682 (12,881, 18,484) | 20,477 (15,389, 25,565) |
| SDQ: Total Difficulties scoreb | 5.02 (4.38, 5.65) | 7.21 (5.78, 8.64) | 11.94 (7.34, 16.55) |
| Percent with Statement of Special Educational Need | 0.79 | 8.14 | 50.00 |
| Percent in special school or unit | 0 | 0 | 39.02% |
| Percent referred to speech‐language therapy services | 22.57% | 54.65% | 84.09% |
a
Mean values for children with LD‐only differ significantly, t(440) = 5.31, p < .001. There are no other significant group differences.
b
Both LD‐only and LD‐plus groups have significantly increased symptom severity scores relative to TD peers: t(440) = 2.76, p = .006 and t(399) = 2.93, p = .004 respectively.
