Little information is available on the prevalence of Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 eating disorders in adolescence, and eating disorders remain unique in the DSM for not systematically including a criterion for clinical significance. This study aimed to provide the first prevalence report of the full suite of DSM-5 eating disorders in adolescence, and to examine the impact of applying a criterion for clinical significance.
In total, 5191 (participation rate: 70%) Australian adolescents completed a survey measuring 1-month prevalence of eating disorder symptoms for all criterial, ‘other specified’ and unspecified eating disorders, as well as health-related quality of life and psychological distress.
The point prevalence of any eating disorder was 22.2% (12.8% in boys, 32.9% in girls), and ‘other specified’ disorders (11.2%) were more common than full criterial disorders (6.2%). Probable bulimia nervosa and binge eating disorder, but not anorexia nervosa (AN), were more likely to be experienced by older adolescents. Most disorders were associated with an increased odds for being at a higher weight. The prevalence of eating disorders was reduced by 40% (to 13.6%) when a criterion for clinical significance was applied.
Eating disorders, particularly ‘other specified’ syndromes, are common in adolescence, and are experienced across age, weight, socioeconomic and migrant status. The merit of adding a criterion for clinical significance to the eating disorders, similar to other DSM-5 disorders, warrants consideration. At the least, screening tools should measure distress and impairment associated with eating disorder symptoms in order to capture adolescents in greatest need for intervention.
Insomnia treatment using an internet-based cognitive–behavioural therapy
for insomnia (CBT-I) program reduces depression symptoms, anxiety
symptoms and suicidal ideation. However, the speed, longevity and
consistency of these effects are unknown.
To test the following: whether the efficacy of online CBT-I was sustained
over 18 months; how rapidly the effects of CBT-I emerged; evidence for
distinct trajectories of change in depressive symptoms; and predictors of
A randomised controlled trial compared the 6-week Sleep Healthy Using the
Internet (SHUTi) CBT-I program to an attention control program. Adults
(N=1149) with clinical insomnia and subclinical
depression symptoms were recruited online from the Australian
Depression, anxiety and insomnia decreased significantly by week 4 of the
intervention period and remained significantly lower relative to control
for >18 months (between-group Cohen's d=0.63, 0.47,
0.55, respectively, at 18 months). Effects on suicidal ideation were only
short term. Two depression trajectories were identified using growth
mixture models: improving (95%) and stable/deteriorating (5%) symptoms.
More severe baseline depression, younger age and limited comfort with the
internet were associated with reduced odds of improvement.
Online CBT-I produced rapid and long-term symptom reduction in people
with subclinical depressive symptoms, although the initial effect on
suicidal ideation was not sustained.
We must begin with names. ‘Tony Edwards’ is the person to whom this volume is dedicated, but it is not a name that everyone will immediately recognize, particularly those who know him only from his published work, for he has made himself known in public, from the first, as A. S. G. Edwards. When he began his career, this was the manner in which most scholars, most men at least, named themselves. Fashions have changed, and given names, one, two, or more, are now almost universal. But Tony has held on tenaciously to his initials, perhaps because he has three of them. We do not believe that he did so in any spirit of emulation of or desire to align himself with ‘Edwards A. S. G.’, the Edwards Active Strain Gauge well known to Google, an advanced form of technical engineering equipment which guarantees the vacuum conditions needed for the manufacture of certain precision instruments, such as aircraft engine turbine blades. It seems strangely apt as an analogous form of ‘A. S. G.’, whether one thinks of the ‘active strain’ involved as what he exerts upon himself or upon other people. The analogy fails, of course, when one comes to the creation of vacuum, where it works back to front, for Tony's work has essentially been to fill the vacuum that once existed in the study of manuscript history.
Late medieval manuscripts and early modern print history form the focus of this volume. It includes new work on the compilation of some important medieval manuscript miscellanies and major studies of merchant patronage and of a newly revealed woman patron, alongside explorations of medieval texts and the post-medieval reception history of Langland, Chaucer and Nicholas Love. It thus pays a fitting tribute to the career of Professor A.S.G. Edwards, highlighting his scholarly interests and demonstrating the influence of his achievements. Carol M.
