    INTRODUCTION: Depression is highly prevalent and the leading contributor to the burden of disease in young people worldwide, making it an ongoing priority for early intervention. As the current evidence-based interventions of medication and psychological therapy are only modestly effective, there is an urgent need for additional treatment strategies. This paper describes the rationale of the Improving Mood with Physical ACTivity (IMPACT) trial. The primary aim of the IMPACT trial is to determine the effectiveness of a physical activity intervention compared with psychoeducation, in addition to routine clinical care, on depressive symptoms in young people. Additional aims are to evaluate the intervention effects on anxiety and functional outcomes and examine whether changes in physical activity mediate improvements in depressive symptoms. METHODS AND ANALYSIS: The study is being conducted in six youth mental health services across Australia and is using a parallel-group, two-arm, cluster randomised controlled trial design, with randomisation occurring at the clinician level. Participants aged between 12 years and 25 years with moderate to severe levels of depression are randomised to receive, in addition to routine clinical care, either: (1) a physical activity behaviour change intervention or (2) psychoeducation about physical activity. The primary outcome will be change in the Quick Inventory of Depressive Symptomatology, with assessments occurring at baseline, postintervention (end-point) and 6-month follow-up from end-point. Secondary outcome measures will address additional clinical outcomes, functioning and quality of life. IMPACT is to be conducted between May 2014 and December 2019. ETHICS AND DISSEMINATION: Ethical approval was obtained from the University of Melbourne Human Research Ethics Committee on 8 June 2014 (HREC 1442228). Trial findings will be published in peer-reviewed journals and presented at conferences. Key messages will also be disseminated by the youth mental health services organisation (headspace National Youth Mental Health Foundation). TRIAL REGISTRATION NUMBER: ACTRN12614000772640.

    The effectiveness of simple psychological and physical activity interventions for high prevalence mental health problems in young people: A factorial randomised controlled trial
    Parker, AG ; Hetrick, SE ; Jorm, AF ; Mackinnon, AJ ; McGorry, PD ; Yung, AR ; Scanlan, F ; Stephens, J ; Baird, S ; Moller, B ; Purcell, R (ELSEVIER SCIENCE BV, 2016-05-15)
    BACKGROUND: The prevalence and burden of disease of depression and anxiety disorders in young people necessitates effective early intervention strategies. The aim of this study was to evaluate the effectiveness of low-intensity interventions (problem solving therapy (PST) and physical activity promotion) in young people (15-25 years) with mild-moderate depression and/or anxiety. METHOD: A 2×2 factorial randomised controlled trial (RCT) with factors of PST versus supportive counselling (control) and behavioural activation physical activity versus lifestyle psychoeducation (control). Help-seeking participants (n=176) were randomised to receive up to 6 manualised intervention sessions. Primary outcomes were post-intervention depressive symptoms (Beck Depression Inventory-II (BDI-II), anxiety symptoms (Beck Anxiety Inventory), and Montgomery-Åsberg Depression Rating Scale (MADRS)). Trial registration ACTRN12608000550303. RESULTS: Depression symptoms were significantly reduced in the physical activity group compared to psychoeducation (BDI-II: d=0.41 (95% CI: 0.07-0.76); MADRS: d=0.48 (95% CI: 0.13-0.82), but not post-intervention anxiety symptoms. PST was not superior to supportive counselling, nor were any interactions between interventions significant. LIMITATIONS: As self reported levels of physical activity did not significantly differ between baseline and end-point in those randomised to the physical activity intervention, it is unclear as to whether some form of physical activity not measured in the trial may have led to the difference in depression symptoms. CONCLUSIONS: PST was not superior to supportive counselling in reducing depression and anxiety symptoms in young people. Participants who received the physical activity intervention reported the greatest reduction in depression symptoms, however further research is required to establish the mechanism of action and to determine its effectiveness as an adjunct intervention in routine clinical practice.

    Stigmatising attitudes of undergraduates towards their peers with depression: a cross-sectional study in Sri Lanka
    Amarasuriya, SD ; Jorm, AF ; Reavley, NJ ; Mackinnon, AJ (BMC, 2015-06-19)
    BACKGROUND: There is limited research examining mental health-related stigma of undergraduates in non-western developing countries. This study examined stigma of undergraduates in Sri Lanka towards another depressed undergraduate. METHODS: A hypothetical vignette of an undergraduate suffering from depression was presented. A total of 4650 undergraduates responded to scales assessing their personal stigma towards and desire for social distance from this individual. Exploratory structural equation modelling (ESEM) was performed to determine the dimensionality and loading pattern of the items on these two stigma scales. Multiple linear regressions were used to explore correlates of the identified dimensions of stigma. RESULTS: Previous findings that the Social Distance Scale forms a single dimension and that the Personal Stigma Scale consists of two dimensions were supported. However, the measurement structure of the dimensions of stigma on the latter scales, labelled 'Weak-not-Sick' and 'Dangerous-Undesirable' , differed from previous work. A high level of stigma in relation to the 'Weak-not-Sick' Scale was observed. However, some correlates associated with lower levels of stigma on this scale, such as being in the Medical Faculty, were associated with higher levels of stigma on the 'Dangerous-Undesirable' and 'Social Distance' scales. In contrast, labelling the problem as a mental health-related problem, with absence of specific psychiatric terminology, was associated with lower levels of stigma on these latter two scales. Exposure to a mental health problem in family or friends or from personal experience was also associated with lower stigma on the Social Distance Scale. However, the effect sizes of these relationships were small. CONCLUSIONS: The findings highlight differences in the measurement structure and score distribution of the 'Weak-not-Sick' and 'Dangerous-Undesirable' scales when used in different cultural and demographic contexts. The dimensionality of stigma relevant to these scales must always be established prior to their use in different contexts. Furthermore, campaigns targeted at improving knowledge about depression as a real illness and as a psychiatric condition need to ensure that such attempts are not associated with increases in other aspects of stigma.

    Behavior change through automated e-mails: Mediation analysis of self-help strategy use for depressive symptoms
    Morgan, AJ ; Mackinnon, AJ ; Jorm, AF (PERGAMON-ELSEVIER SCIENCE LTD, 2013-02)
    OBJECTIVE: To evaluate whether automated e-mails promoting effective self-help strategies for depressive symptoms were effective in changing self-help behavior, and whether this improved depression outcomes. METHOD: 568 adults with sub-threshold depression participated in a randomized controlled trial and provided complete data. A series of 12 e-mails promoting the use of evidence-based self-help strategies was compared with e-mails providing non-directive depression information. Depression symptoms were assessed with the Patient Health Questionnaire depression scale (PHQ-9) and use of self-help strategies was assessed at baseline and post-intervention. We hypothesized that those receiving the self-help e-mails would increase their use of evidence-based self-help and this would be associated with improvements in depression. Mediation analyses were conducted using a non-parametric bootstrapping procedure. RESULTS: Total use of the self-help strategies promoted in the e-mails significantly mediated the effect of the intervention on depressive symptoms (B = -0.75, SE = 0.16, 95% CI: -1.06 to -0.48). The direct effect of the intervention on depressive symptoms was much smaller and not significant when the mediation path was included. The majority of the individual strategies also had a significant indirect effect on depressive symptoms. CONCLUSIONS: In adults with sub-threshold depression, automated e-mails based on behavior change principles can successfully increase use of self-help strategies, leading to a reduction in depressive symptoms.

    Internet-Based Recruitment to a Depression Prevention Intervention: Lessons From the Mood Memos Study
    Morgan, AJ ; Jorm, AF ; Mackinnon, AJ (JMIR PUBLICATIONS, INC, 2013-02)
    BACKGROUND: Recruiting participants to randomized controlled trials of health interventions can be very difficult. Internet-based recruitment is becoming an increasingly important mode of recruitment, yet there are few detailed accounts of experiences recruiting participants to mental health interventions. OBJECTIVE: To report on our experience with Internet-based recruitment to an online depression prevention intervention and pass on lessons we learned. METHODS: Participants were recruited to the Mood Memos study, an online preventive depression intervention, purely through Internet-based sources. The study was targeted to adults with subthreshold depression symptoms from several English-speaking countries. A variety of online recruitment sources were trialed, including search engine advertising (Google, Yahoo!, Bing), Facebook advertising, posts in forums and online noticeboards, and promotion through relevant websites and email newsletters of mental health organizations. RESULTS: The study website received visits from 94,808 individuals over the 14-month recruitment period. The recruitment target was reached with 1699 individuals signing up to the randomized controlled trial and 1326 fully enrolling. Most visitors arrived via Google advertising, which promoted a depression-screening questionnaire. Google advertising accounted for nearly half of the total participants who signed up to the study, at an average cost of AUD $12 per participant. Promoting the study through trustworthy organizations and websites known to participants was also effective. Recruitment techniques that were less effective were contacting forums, email groups, and community noticeboards. CONCLUSIONS: Several techniques, including Google advertising, were successful in recruiting participants to a trial evaluating an online depression intervention. Results suggest that Internet-based recruitment to mental health interventions is feasible and can be relatively affordable. TRIAL REGISTRATION: ACTRN12609000925246.
