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.

Physical activity theories have almost exclusively focused on conscious regulatory processes such as plans, beliefs, and expected value. The aim of this review was to aggregate the burgeoning evidence showing that physical activity is also partially determined by non-conscious processes (e.g., habits, automatic associations, priming effects). A systematic search was conducted and study characteristics, design, measures, effect size of the principle summary measures, and main conclusions of 52 studies were extracted by two independent coders. The findings support that habitual regulatory processes measured via self-report are directly associated with physical activity beyond conscious processes, and that there is likely interdependency between habit strength and intentions. Response latency measures of automatic associations with physical activity were widely disparate, precluding conclusions about specific effects. A small body of evidence demonstrated a variety of priming effects on physical activity. Overall, it is evident that physical activity is partially regulated by non-conscious processes, but there remain many unanswered questions for this area of research. Future research should refine the conceptualisation and measurement of non-conscious regulatory processes and determine how to harness them to promote physical activity.

Inoculation theory, a theory of conferring resistance to persuasive influence, has established efficacy as a messaging strategy in the health domain. In fact, the earliest research on the theory in the 1960s involved health issues to build empirical support for tenets in the inoculation framework. Over the ensuing decades, scholars have further examined the effectiveness of inoculation-based messages at creating robust positive health attitudes. We overview these efforts, highlight the structure of typical inoculation-based health messages, and describe the similarities and differences between this method of counter-persuasion and other preparatory techniques commonly employed by health researchers and practitioners. Finally, we consider contexts in which inoculation-oriented health messages could be most useful, and describe how the health domain could offer a useful scaffold to study conceptual issues of the theory.

This review is designed to advance current conceptualizations of mental toughness in sport as well as identify avenues for future research by offering a fresh perspective using Kelly's (1955/1991) personal construct psychology (PCP). After reviewing sport-general and sport-specific research contributing to current perspectives on mental toughness, we highlight the need for theoretically driven research in the area. Following this, we provide an overview PCP and offer a conceptual model grounded in PCP which attempts to organize the knowledge base as well as provide a platform for future research. In integrating previous research with PCP, we propose a construct definition in which the multidimensional nature of mental toughness, its usefulness for dealing with and thriving through both positively and negatively construed situations, and the processes by which this occurs are highlighted. Specifically, mental toughness is defined as a collection of values, attitudes, emotions, and cognitions that influence the way in which an individual approaches, responds to, and appraises demanding events to consistently achieve his or her goals. To conclude, methodological and conceptual limitations associated with previous research are examined and the PCP model of mental toughness presented here is employed to identify avenues for future research.
