A personal construct psychology (PCP; Kelly, 1955/1991) framework was employed in an attempt to reveal a holistic understanding of mental toughness in the context of Australian Football. Eleven male coaches (M age = 42, SD = 9.62) with considerable playing and coaching experience at the elite level were interviewed using a PCP-based interview protocol. Transcribed verbatim data were analyzed using grounded theory procedures. Three independent categories (characteristics, situations, behaviors) were inductively derived and integrated into a model in which the importance of understanding each component individually was emphasized. The relationship between these three central categories was also highlighted. Results identified the key mental characteristics and their contrasts together with those situations that demand mental toughness, and the behaviors commonly displayed by mentally tough footballers. Conceptualized in the context of these three categories, mental toughness in Australian Football can be considered as a buffer against adversity but also as a collection of enabling factors that promote and maintain adaptation to other challenging situations. Practical implications of the findings are discussed and focus on issues pertaining to enhancing and/or developing mental toughness.

Several interventions have targeted dyads to promote physical activity (PA) or reduce sedentary behaviour (SB), but the evidence has not been synthesised. Sixty-nine studies were identified from MEDLINE, PsycINFO, and Web of Science, and 59 were included in the main meta-analyses (providing 72 independent tests). Intervention details, type of dyadic goal, participant characteristics, and methodological quality were extracted and their impact on the overall effect size was examined. Sensitivity analyses tested effect robustness to (a) the effects of other statistically significant moderators; (b) outliers; (c) data included for participants who were not the main target of the intervention. Dyadic interventions had a small positive, highly heterogeneous, effect on PA g = .203, 95% CI [0.123–0.282], compared to comparison conditions including equivalent interventions targeting individuals. Shared target-oriented goals (where both dyad members hold the same PA goal for the main target of the intervention) and peer/friend dyads were associated with larger effect sizes across most analyses. Dyadic interventions produced a small homogeneous reduction in SB. Given dyadic interventions promote PA over-and-above equivalent interventions targeting individuals, these interventions should be more widespread. However, moderating factors such as the types of PA goal and dyad need to be considered to maximise effects.

Athlete development and management encompass a complex interaction of biological, psychological, and social factors. Within elite sport, multidisciplinary sport science and medicine teams play an important role in achieving an optimal balance between preventing athlete ill-health and optimizing health and performance. The psychological aspects of athlete health and performance have gained increased attention over the past two decades, with much of this research concerned with the mental health of athletes and the concept of mental toughness. Recently, it was proposed that mental health and mental toughness are contradictory concepts in the world of elite sport. Although an interesting proposition, this claim was not substantiated. Thus, the purpose of this narrative review was to evaluate theory and evidence regarding the thesis that mental health and mental toughness are contradictory concepts in the world of elite sport, with the view to advance scholarly knowledge and inform professional practice. Narrative review. A critical evaluation of this literature suggests that mental toughness may represent a positive indicator of mental health, or facilitate its attainment, rather than be at odds with it. When implemented alongside multilayered approaches to organizational change (e.g., group structures, policies), mental toughness could be used as a 'hook' to attract athletes into settings that can open dialogue on the importance of mental health and improve knowledge of key issues (e.g., stigma, symptoms).
