CCT is efficacious on global cognition, select cognitive domains, and psychosocial functioning in people with mild cognitive impairment. This intervention therefore warrants longer-term and larger-scale trials to examine effects on conversion to dementia. Conversely, evidence for efficacy in people with dementia is weak and limited to trials of immersive technologies.

BackgroundSuicide bereavement is a risk factor for adverse outcomes related to grief, social functioning, mental health and suicidal behaviour. Consequently, suicide bereavement support (i.e., postvention) has been identified as an important suicide prevention strategy. However, little is known about its effectiveness. To redress this gap, this review aimed to assess the evidence of effectiveness of interventions for people bereaved by suicide, and appraise the quality of the research in this field.MethodsWe conducted a systematic review according to PRISMA guidelines. Searches of peer-reviewed literature in Medline, PsycINFO, Embase and EBM Reviews identified 12 papers reporting on 11 relevant studies conducted between 1984 and 2018.ResultsAcross studies, there was a wide variety of intervention modalities, study populations, control groups, and grief, psychosocial and suicide-related outcome measures. Overall, the quality of studies was weak. While there was some evidence of the effectiveness of interventions for uncomplicated grief, evidence of the effectiveness of complicated grief interventions was lacking. Based on this scant evidence, interventions which seem to show promise include supportive, therapeutic and educational approaches, involve the social environment of the bereaved, and comprise a series of sessions led by trained facilitators.ConclusionsThere is a clear need for additional methodologically sound studies in this area. Specifically, selection procedures, sample sizes, randomization, and the use of appropriate measures are crucial. As people bereaved by suicide are at-risk of adverse grief, mental ill-health and suicidal behaviour, further research across the life-span is essential to prevent grief and mental health ramifications.

IntroductionMany countries have developed guidelines advocating for responsible reporting of suicidal behaviour in traditional media. However, the increasing popularity of social media, particularly among young people, means that complementary guidelines designed to facilitate safe peer-peer communication are required. The aim of this study was to develop a set of evidence informed guidelines to assist young people to communicate about suicide via social media with the input of young people as active participants of the study.MethodsSystematic searches of the peer-reviewed and grey literature were conducted resulting in a 284-item questionnaire identifying strategies for safe communication about suicide online. The questionnaire was delivered over two rounds to two panels consisting of Australian youth advocates; and international suicide prevention researchers and media and communications specialists. Items were rerated if they were endorsed by 70–79.5% of both panels, or if 80% or more of one panel rated the item as essential or important. All items that were endorsed as essential or important by at least 80% of both panels were included in the final guidelines.ResultsA total of 173 items were included in the final guidelines. These items were organised into the following five sections: 1) Before you post anything online about suicide; 2) Sharing your own thoughts, feelings, or experience with suicidal behaviour online; 3) Communicating about someone you know who is affected by suicidal thoughts, feelings or behaviours; 4) Responding to someone who may be suicidal; 5) Memorial websites, pages and closed groups to honour the deceased.DiscussionThis is the first study to develop a set of evidence-informed guidelines to support young people to talk safely about suicide on social media. It is hoped that they will be a useful resource for young people and those who support them (e.g., parents, teachers, community workers and health professionals).
