AbstractThis systematic review investigated the relationship between peer and/or friend variables and physical activity among adolescents by synthesising cross-sectional, longitudinal, and experimental research conducted in the US. Seven electronic databases were searched to identify related articles published within the last 10 years and the articles reviewed included adolescents between 10 and 18 years. Studies reporting a measure of physical activity for adolescents and at least one potential peer and/or friend variable were included. Research demonstrated that peers and friends have an important role to play in the physical activity behavior of adolescents. Six processes were identified through which peers and/or friends may have an influence on physical activity including: peer and/or friend support, presence of peers and friends during physical activity, peer norms, friendship sport quality and acceptance, peer crowd affiliation, and peer victimization. The theoretical significance of these results is assessed and the development of peer-related physical activity programmes for adolescents is discussed.

Aquatics can be an appropriate and beneficial form of physical activity for people with SPIDs, but there are many barriers to participation. Tailored programmes are required. Further investigation of the experiences of people with SPIDs in relation to physical activity is recommended.

Therapists view self-disconnect as at the core of suicidality and note that toxic relationships also play a critical role. Therapeutic connection can present as a life-saving paradox for people who are suicidal. Risk of death and therapeutic endeavour may present as challenging dynamics for working with people who are suicidal. Some discussion points include the worth of self-compassion development for people who are suicidal, the rephrasing of "psychotherapy" when trying to save someone's life and the emphasis on relationship skills for all healthcare professionals who encounter people who are suicidal. Clinical or methodological significance of this article: This article is one of the first in which therapists are interviewed about their understandings of suicide and the processes of suicide in the therapeutic space. It offers novel insights about how people who are suicidal present in therapy and what may be contributing to this presentation. The research also gives insights on the struggles for therapists working with people who are suicidal and who may be ambiguous about the prospect of therapy and connecting. The study also offers important direction for future studies in relation to what requires further discussion and exploration regarding engaging in therapy with people who are suicidal. In addition, the current study can offer previously unexplored insights regarding suicide and therapy that may have the potential to assist in future intervention for people who are risk of killing themselves.

Given that depression is one of the biggest challenges the world faces at present, further research is required to examine the effectiveness of treatment for different levels of depression severity.

PurposeActs of violent extremism have become more regular in the past decade. Little research has managed to analyse the interplay between the individuals who have carried out these acts and those who have experienced them. By bringing two such groups together in direct contact with each other, The Summit Against Violent Extremism (SAVE) offered a unique opportunity to explore the experiences of former violent extremists and victims of terrorist acts. This article aims to focus on this initiative.Design/methodology/approachThe article is designed to take the reader through the discussions of three senior psychologists who attended SAVE to offer support to all involved. Their experiences and insights were gathered, within a focus group, to develop themes with the aim to discuss and share.FindingsPsychologists outlined social development, self‐identity, family and peer groups as critical to the development of extremist views and to the de‐radicalisation of such views. It was reported that the summit gave survivors a chance to express their anger in a positive setting but that this setting could be improved for future summits. Challenges that faced the psychologists included the multi‐lingual environment and confidentiality issues.Practical implicationsThe summit was seen as a successful means for developing an understanding of those who have taken part in acts of extreme violence and terror. The psychologists provide practical suggestions for future de‐radicalisation of people in extremist groups.Originality/valueThe role of therapeutic psychologists in such a summit was viewed as critically important as a support to both formers and survivors.

This paper details preliminary explorations of how the Power Threat Meaning Framework (PTMF) may be applied in an early intervention youth mental health service. The PTMF is discussed under the organisation’s strategic priority of influencing change regarding youth mental health in Ireland.
