sleep-onset difficulties in an adolescent sample.
Methods: Participants were 385 students (59% male) from grades 9 to 11, between 13
and 18 yrs old (M=15.6, SD=1.0), from 8 co-educational high schools of varied socioeconomic
status in metropolitan Adelaide, South Australia. The cross-sectional study
used a questionnaire battery including the Sleep Anticipatory Anxiety Questionnaire -
Adolescent Version [SAAQ-A], completed during school time, followed by 8 days of
sleep diary completion and wearing wrist actigraphy to obtain subjective and
objective sleep onset latency [SOL].
Results: Significant relationships were found between somatic arousal (SAAQ-A
subscale) and objective SOL, and between sleep-related cognitions (SAAQ-A
subscale) and subjective SOL and SOL overestimation (sleep misperception). No
relationships were found between subjective SOL and somatic or rehearsal and
planning cognitions. Objective SOL was not related to rehearsal and planning, or
sleep-related cognition scores, and sleep misperception had no relationship with
somatic, and rehearsal and planning cognition scores.
Conclusions: These findings are similar to those in clinical adult populations, but also
notably different, for example the lack of association between negative sleep-related
pre-sleep cognitions and objective sleep difficulty. This study’s results provide a basis
for existing relationships between negative pre-sleep cognitions and subjective and
objective sleep difficulties in this population to be examined causally in more detail

The contribution of peer and media influences to the development of body satisfaction and self-esteem in young girls: a prospective study
This study aimed to prospectively examine the role of peer and media influences in the development of body satisfaction (incorporating the desire for thinness and satisfaction with appearance) in young girls, as well as the relationship between body satisfaction and self-esteem. 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. In addition, the watching of appearance-focused television programs was temporally antecedent to appearance satisfaction. Finally, girls ’ desire for thinness was found to temporally precede low self-esteem. Thus, as early as school entry, girls appear to already live in a culture in which peers and the media transmit the thin ideal in a way that negatively influences the development of body image and self-esteem
Family disorganization, sleep hygiene, and adolescent sleep disturbance
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 = 14.9, SD = 1.0) years, (43% male), recruited from four high schools in South Australia. Sleep hygiene fully mediated the relationship between family disorganization and sleep onset latency (z = 2.77, p < .01) and daytime sleepiness (z = 3.47, p < .01). Only partial mediation was evident for total sleep time (z = 2.50, p < .05). These findings suggest that consideration should be given to the family environment when assessing sleep disturbance in adolescents, and subsequently implementing interventions.8 page(s
