BackgroundHealthy Together Victoria (HTV) - a complex ‘whole of system’ intervention, including an embedded cluster randomized control trial, to reduce chronic disease by addressing risk factors (physical inactivity, poor diet quality, smoking and harmful alcohol use) among children and adults in selected communities in Victoria, Australia (Healthy Together Communities).ObjectivesTo describe the methodology for: 1) assessing changes in the prevalence of measured childhood obesity and associated risks between primary and secondary school students in HTV communities, compared with comparison communities; and 2) assessing community-level system changes that influence childhood obesity in HTC and comparison communities.MethodsTwenty-four geographically bounded areas were randomized to either prevention or comparison (2012). A repeat cross-sectional study utilising opt-out consent will collect objectively measured height, weight, waist and self-reported behavioral data among primary [Grade 4 (aged 9-10y) and Grade 6 (aged 11-12y)] and secondary [Grade 8 (aged 13-14y) and Grade 10 (aged 15-16y)] school students (2014 to 2018). Relationships between measured childhood obesity and system causes, as defined in the Foresight obesity systems map, will be assessed using a range of routine and customised data.ConclusionThis research methodology describes the beginnings of a state-wide childhood obesity monitoring system that can evolve to regularly inform progress on reducing obesity, and situate these changes in the context of broader community-level system change.

A Severity of Amphetamine Dependence Questionnaire (SAmDQ) was administered to 101 subjects attending an Australian drug dependency treatment centre. The SAmDQ was adapted from the Severity of Opiate and Alcohol Dependence Questionnaires (SODQ & SADQ). The structural characteristics of the SAmDQ were examined and compared with previous findings reported on samples of opiate addicts with the SODQ. A high degree of consistency was found between the results obtained with the SAmDQ and previous findings with the SODQ. The relationship between the SAmDQ and the Severity of Dependence Scale (SDS) was also examined. The findings suggest that further development of amphetamine dependence measurement is required.
