| 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. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
