This paper presents a report of some of the activities of the International Energy Agency's (IEA) Wind TCP Task 39. By identifying best practices in an international collaboration, Task 39 hopes to provide the scientific evidence to inform improved regulations and standards, increasing the effectiveness of quiet wind turbine technology. Task 39 is divided into five separate work packages, which address the broad wind turbine noise topic in successive steps; from wind turbine noise generation (WP2), to airborne noise propagation over large distances (WP3). The assessment of wind turbine noise and its impact on humans is addressed in WP4, while WP5 is dealing with other aspects of perception and acceptance, which may be related to noise. All WPs contribute to a dedicated Work Package on dissemination (WP1). This paper provides an update of activities primarily associated with the socio-psychological aspects of wind turbine noise (WP4 and WP5). Through the consideration of a wide variety of factors, including measurement technologies, auralisation and psychology, the effects on noise perception, annoyance and its impact on wellbeing and health is being further investigated. This paper presents a discussion of the activities of each member country and highlights some of the key research questions that need to be further considered.

Research on psychological treatment of depression in inpatients is not conclusive,with some studies finding clear positive effects and other studies finding no significant benefit compared to usual care or structured pharmacotherapy. The results of a meta-analysis investigating how effective psychological treatment is for depressed inpatients are presented. A systematic search in bibliographical databases resulted in 12 studieswith a total of 570 respondents. This set of studies had sufficient statistical power to detect small effect sizes. Psychological treatments had a small (g=0.29), but statistically significant additional effect on depression compared to usual care and structured pharmacological treatments only. This corresponded with a numbersneeded- to-be-treated of 6.17. Heterogeneity was zero inmost analyses, and not significant in all analyses. There wasno indication for significant publication bias. Effectswere not associatedwith characteristics of the population, the interventions and the design of the studies. Although the number of studieswas small, and the quality ofmany studieswas not optimal, it seems safe to conclude that psychological treatments have a small but robust effect on depression in depressed inpatients. More high-quality research is needed to verify these results.

Abstract Objectives The aim of this review is to establish the effectiveness of psychological relapse prevention interventions, as stand-alone interventions and in combination with maintenance antidepressant treatment (M-ADM) or antidepressant medication (ADM) discontinuation for patients with remitted anxiety disorders or major depressive disorders (MDD). Methods A systematic review and a meta-analysis were conducted. A literature search was conducted in PubMed, PsycINFO and Embase for randomised controlled trials (RCTs) comparing psychological relapse prevention interventions to treatment as usual (TAU), with the proportion of relapse/recurrence and/or time to relapse/recurrence as outcome measure. Results Thirty-six RCTs were included. During a 24-month period, psychological interventions significantly reduced risk of relapse/recurrence for patients with remitted MDD (RR 0.76, 95% CI: 0.68–0.86, p<0.001). This effect persisted with longer follow-up periods, although these results were less robust. Also, psychological interventions combined with M-ADM significantly reduced relapse during a 24-month period (RR 0.76, 95% CI: 0.62–0.94, p = 0.010), but this effect was not significant for longer follow-up periods. No meta-analysis could be performed on relapse prevention in anxiety disorders, as only two studies focused on relapse prevention in anxiety disorders. Conclusions In patients with remitted MDD, psychological relapse prevention interventions substantially reduce risk of relapse/recurrence. It is recommended to offer these interventions to remitted MDD patients. Studies on anxiety disorders are needed.
