There have been a number of national surveys of psychiatric morbidity, which have included questions on drugs, alcohol, and tobacco. These surveys have helped delineate the overlap between substance use and dependence and other psychological morbidity. There is a strong association reported between high substance consumption and other measures of psychological problems. This article provides an overview of a national household survey, a survey of institutional residents with psychiatric disorders, and a national survey of a homeless population. All three surveys used comprehensive and complex sampling strategies and lay interviewers to conduct structured diagnostic interviews. The household survey included over 10,000 households, the institutional survey interviewed 755 individuals, and the homeless survey of hostels, night shelters, day centres, and private sector leased accommodation interviewed 1,061 individuals. This overview looks at patterns of nicotine, alcohol, and other drug use in the different samples and examines interactions with other psychiatric morbidity. The survey reports that substance-related disorders are some of the commonest disorders in the community, with 5% of the household sample alcohol dependent, 7% alcohol dependent in the institutional sample and over 21% in the homeless sample recorded as alcohol dependent. Tobacco, alcohol and other drug use and dependence were dramatically higher in the homeless sample than in either of the other two samples. Substance use was significantly associated with higher rates of psychological morbidity as measured by the Clinical Interview Schedule Revised. Future service planning needs to take account of the striking disparity of prevalence of psychiatric disorders in different subsections of the population.

With reference to clinical and normative school-age populations, future studies should be directed toward determining validated standard FMS assessments to enable accurate effect estimates, permit intervention comparisons and improve the efficacy of FMS development.

Background. A growing body of research has linked social media use to negative body image.Aims. The present research aimed to evaluate the efficacy of Digital Bodies, a brief classroom-based intervention that aims to improve adolescents' body image.Methods. British adolescents (N = 290; Age M = 12.81; SD = 0.40; Range = 12-13; Female = 151) were cluster randomized to intervention or waiting list control groups. Measures of body satisfaction, appearance ideal internalization (thin and athletic ideal internalization) and self-objectification were completed at baseline (T1), 1-week postintervention (T2) and 8-week follow-up (T3).Results. Multi-level modelling showed adolescents in the intervention group reported improved body satisfaction at T2, in comparison to the control, and crucially this effect was sustained at T3. Additionally, girls reported less thin ideal internalization at T2 relative to the control, but this effect was not sustained at T3. No other intervention effects were found.Conclusions. Overall, the findings provide initial support for the efficacy of Digital Bodies as an intervention for improving adolescents' body satisfaction.
