Study Objectives: To examine the relationship between pre-sleep cognitions and sleep-onset difficulties in an adolescent sample.
Methods: Participants comprised 385 students (59% male) from grades 9 to 11, aged between 13 and 18 years (M = 15.6, SD = 1.
Cognitive processes play an important role in the maintenance, and treatment of sleep difficulties, including insomnia. In 2002, a comprehensive model was proposed by Harvey. Since its inception the model has received >300 citations, and provided researchers and clinicians with a framework for understanding and treating insomnia.

Methods: Three-hundred seventy-four Australian adolescents (mean age 15.6 years, SD 1.
Aim: Adolescent sleep patterns vary between countries, and these differences influence adolescent functioning and well-being. The present study provides data on the sleep and well-being of Australian adolescents.
Methods: 385 adolescents aged 13-18 years were recruited from 8 South Australian schools spanning the socio-economic spectrum.
Study Objectives: Many studies of adolescent insomnia use experience of insomnia-like symptoms to categorize "caseness." This is likely to lead to inflated prevalence and may have important ramifications for the research using individual symptoms to operationalize insomnia. The aim of the present study was to contrast the occurrence of insomnia symptoms with cases of insomnia diagnosed using criteria from the fourth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) and the second edition of the International Classification of Sleep Disorders (ICSD-II) in a sample of Australian adolescents.

Design: Randomized controlled trial of CBT plus BLT vs. waitlist (WL) control with comparisons at pre- and post-treatment.
Study Objectives: To determine the proportion of adolescents whose bedtime is set by their parents and to evaluate whether parent-set bedtimes are associated with earlier bedtimes, more sleep, and better daytime functioning.
Participants: 385 adolescents aged 13-18 years (mean = 15.6, SD = 0.
Adolescent sleep health is becoming increasingly recognized internationally as a significant concern, with many countries reporting high incidences of sleep disturbance in our youth. Notwithstanding the value of findings obtained from each large-scale survey of adolescent sleep performed within individual countries, the field lacks synthesis and analysis of adolescent sleep studies into a single review. This review presents findings from a meta-analysis of 41 surveys of worldwide adolescent sleep patterns and problems published in the last decade (1999-2010).

The present study investigated the capacity of presleep video-game playing to extend sleep latency and reduce subjective feelings of sleepiness in adolescents. The arousing psychophysiologic mechanisms involved and the impact of presleep video-game playing on sleep architecture were also explored.

The link between sleep hygiene and adolescent sleep is well documented, though evidence suggests contributions from other factors, particularly the family environment. The present study examined whether sleep hygiene mediated the relationship between family disorganization and self-reported sleep onset latency, total sleep time, and daytime sleepiness in adolescents. Participants were 217 adolescents, aged 13 to 18 (M = 14.

The aim of the current research was to evaluate Shapesville, a children's picture book designed to promote positive body image in young children. Participants were a convenience sample comprising 84 girls (aged 5-9 years) recruited from four private girls' schools. Girls were randomly allocated to be read either Shapesville or a control book.

A sample of 97 girls 5-8 years of age completed individual interviews at Time 1 and 1 year later at Time 2. Linear panel analyses found that Time 1 perception of peers' desire for thinness was temporally antecedent to girls' desire for thinness, appearance satisfaction, and self-esteem 1 year later.
