| Abstract |
The present study investigated the prevalence and heritability of nightmares and their comorbidity with psychopathology in a sample (N = 1,318) of children, adolescents, and child and adolescent twins ranging in age from 4 to 17 years old. The prevalence of terrible nightmares was estimated to be 6.4%, which is similar to previous studies. There were marginal gender differences in this rate (7.7% for boys; 5.1% in girls), contrary to previous studies that purport higher rates for girls. There was little evidence for prevalence changes across age. Nightmares were highly heritable and attributed to an additive genetic influence (51%) and nonshared environmental effects (49%). There was little evidence for a shared genetic correlation for nightmares and generalized waking anxiety (Overanxious Disorder of Childhood). There was also a substantial and pervasive comorbid psychopathology for those parents who reported Strongly True on Item 59: My child has terrible nightmares on the 200-item parent-as-respondent, Coolidge Personality and Neuropsychological Inventory. Issues in estimating prevalence rates of nightmares were identified. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 November 2013.
All research outputs
#18,347,414
of 22,721,584 outputs
Outputs from Behavior Genetics
#726
of 907 outputs
Outputs of similar age
#85,194
of 93,366 outputs
Outputs of similar age from Behavior Genetics
#8
of 8 outputs
Altmetric has tracked 22,721,584 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 907 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.8. This one is in the 12th percentile – i.e., 12% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 93,366 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 4th percentile – i.e., 4% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one.
