The authors assessed the association of smoking with dementia and cognitive decline in a meta-analysis of 19 prospective studies with at least 12 months of follow-up. Studies included a total of 26,374 participants followed for dementia for 2-30 years and 17,023 participants followed up for 2-7 years to assess cognitive decline. Mean study age was 74 years. Current smokers at baseline, relative to never smokers, had risks of 1.79 (95% confidence interval (CI): 1.43, 2.23) for incident Alzheimer's disease, 1.78 (95% CI: 1.28, 2.47) for incident vascular dementia, and 1.27 (95% CI: 1.02, 1.60) for any dementia. Compared with those who never smoked, current smokers at baseline also showed greater yearly declines in Mini-Mental State Examination scores over the follow-up period (effect size (beta)=-0.13, 95% CI: -0.18, -0.08). Compared with former smokers, current smokers at baseline showed an increased risk of Alzheimer's disease (relative risk=1.70, 95% CI: 1.25, 2.31) and an increased decline in cognitive abilities (effect size (beta)=-0.07, 95% CI: -0.11, -0.03), but the groups were not different regarding risk of vascular dementia or any dementia. The authors concluded that elderly smokers have increased risks of dementia and cognitive decline.

The aim in the current study was to investigate the effectiveness of an online, self-directed cognitive-behavioral therapy program (MoodGYM) in preventing and reducing the symptoms of anxiety and depression in an adolescent school-based population. A cluster randomized controlled trial was conducted with 30 schools (N = 1,477) from across Australia, with each school randomly allocated to the intervention or wait-list control condition. At postintervention and 6-month follow-up, participants in the intervention condition had significantly lower levels of anxiety than did participants in the wait-list control condition (Cohen's d = 0.15-0.25). The effects of the MoodGYM program on depressive symptoms were less strong, with only male participants in the intervention condition exhibiting significant reductions in depressive symptoms at postintervention and 6-month follow-up (Cohen's d = 0.27-0.43). Although small to moderate, the effects obtained in the current study provide support for the utility of universal prevention programs in schools. The effectiveness of booster sessions should be explored in future research.

Relative to typical children, SLI children experience clinically important increases in the severity of diverse emotional, behavioural and ADHD symptoms and more frequently show a clinical level of these problems. The small number of studies included in pooled analysis and methodological heterogeneity reduce the precision and generalisability of the findings. Most studies do not account for initial levels of EB problems.

This study evaluated the effectiveness of a cognitive behaviour therapy Internet program (MoodGYM) for depressive symptoms, attributional style, self-esteem and beliefs about depression, and on depression and depression-vulnerable status in male youth. A total of 78 boys age 15 and 16 years were allocated to either undertake MoodGYM or to standard personal development activities. Outcomes were measured before commencement, post-program and 16 weeks post-program. There were no significant between-group differences in change scores pre- to post- or pre- to follow-up using the intention to treat sample or for participants with post- and/or follow-up data. For boys completing 3 or more modules there were small relative benefits of MoodGYM for depressive symptoms (Effect Size, ES = 0.34), attributional style (ES = 0.17) and self-esteem (ES = 0.16) at post-program, although only the effect for self-esteem was sustained at follow-up. Both groups showed improvement in their beliefs about depression at follow-up, with the control group showing a moderate relative benefit (ES = 0.40). While the numbers are small, there was a reduction in the risk of being depressed in the MoodGYM group of 9% at post-treatment compared with a slightly increased risk for the control group. The risk of being classified as vulnerable to depression reduced by 17% in the MoodGYM group at post-treatment compared with no change in risk for the control group. These reductions in risk for the MoodGYM group were not sustained at follow-up. The limitations of the study highlight several important challenges for MoodGYM and other self-directed Internet cognitive behaviour therapy programs. These include how to ensure enough of the program is received and that people who could potentially benefit access the program and continue to remain engaged with it, and how to enhance the sustainability of any benefits.

Background: This study evaluates the benefits of a self-directed Internet intervention for depression (MoodGYM) delivered as a part of the high school curriculum. Method: One hundred and fifty-seven girls, aged 15 and 16 years, were allocated to undertake either MoodGYM or their usual curriculum. MoodGYM's impact on depressive symptoms, risk of depression, attributional style, depression literacy and attitudes toward depression was examined using random effect regression. Results: MoodGYM produced a significantly faster rate of decline in depressive symptoms over the trial period than the control condition. The effect size for MoodGYM was not significant immediately after the intervention (Cohen's d 5 .19, 95% CI À.18-.56) but was moderate and significant 20 weeks after the intervention (d 5 .46, 95% CI .10-.82). Girls with high depression scores before intervention showed the strongest benefits on self-reported depression at follow-up (d 5 .92, 95% CI .10-1.38). There were no significant intervention effects on depression status, attributional style, depression literacy, and attitudes. Approximately 70% of girls in the MoodGYM group completed less than three of its modules and completion of fewer modules was related to high depression score before intervention. Conclusions: The findings suggest that there are benefits from MoodGYM on self-reported depressive symptoms but has low rates of completion highlight problems in ensuring adherence to Internet programs for depression.

Nineteen empirical studies providing evidence about the nature of trauma narratives in posttraumatic stress disorder (PTSD) were reviewed. Selected studies had participants with a diagnosis of PTSD or with PTSD symptoms. The studies used either linguistic indices or participants' rating of narrative quality. There was evidence of a relationship between PTSD specific pathology and the occurrence of sensory/perceptual references and disturbed temporal aspects. Evidence for PTSD-related narrative fragmentation was inconclusive, and there were little data about specific self-referential content. Poor validity and confusion of content and syntactic aspects of narrative organization limited the data on the organization of PTSD narratives. Approaches that address some of these limitations and allow narrative-based evaluation of memory for trauma in PTSD are outlined.

In everyday social interactions, people's facial expressions sometimes reflect genuine emotion (e.g., anger in response to a misbehaving child) and sometimes do not (e.g., smiling for a school photo). There is increasing theoretical interest in this distinction, but little is known about perceived emotion genuineness for existing facial expression databases. We present a new method for rating perceived genuineness using a neutral-midpoint scale (-7 = completely fake; 0 = don't know; +7 = completely genuine) that, unlike previous methods, provides data on both relative and absolute perceptions. Normative ratings from typically developing adults for five emotions (anger, disgust, fear, sadness, and happiness) provide three key contributions. First, the widely used Pictures of Facial Affect (PoFA; i.e., Bthe Ekman faces^) and the Radboud Faces Database (RaFD) are typically perceived as not showing genuine emotion. Also, in the only published set for which the actual emotional states of the displayers are known (via self-report; the McLellan faces), percepts of emotion genuineness often do not match actual emotion genuineness. Second, we provide genuine/fake norms for 558 faces from several sources (PoFA, RaFD, KDEF, Gur, FacePlace, McLellan, News media), including a list of 143 stimuli that are event-elicited (rather than posed) and, congruently, perceived as reflecting genuine emotion. Third, using the norms we develop sets of perceived-as-genuine (from eventelicited sources) and perceived-as-fake (from posed sources) stimuli, matched on sex, viewpoint, eye-gaze direction, and rated intensity. We also outline the many types of research questions that these norms and stimulus sets could be used to answer.
