I thank my family and close friends who have supported me during times of doubt and illness. They have been my rock and without their support, I wouldn’t have been able to complete. I thank my colleagues, staff and interns at Positive Psychology Institute who gave me time, space and practical support. I thank my clients who already believe in the idea of becoming mentally fit.
I thank the students who participated in the data gathering. CONCEPTUALISING AND MEASURING MENTAL FITNESS 8 CITATIONS FOR PAPERS SUBMITTED FOR PUBLICATION Robinson, P. Conceptualising mental fitness. Manuscript submitted for publication.
Conceptualising and measuring mental fitness: a Delphi Study. (2014c) A multifactorial model of mental fitness. Manuscript submitted for publication. CONCEPTUALISING AND MEASURING MENTAL FITNESS 9 Abstract Despite the increasing use of the term mental fitness, there are no consistent theoretical foundations, models or reliable and valid measures to use in research and practice.
By using the adjective ‘mental’ prior to fitness, mental fitness can be seen as analogous to physical fitness. Physical fitness is a better known domain and it can be used to enable people to grasp potential meanings of mental fitness. To commence the process of defining and measuring mental fitness, a conceptual review and two studies were conducted. The purpose of the conceptual review was to explore the historical, popular and scientific meaning and use of the term mental fitness and how it could be utilised within psychology.
The review provided evidence to formulate an initial definition of mental fitness and a set of four guiding principles. Further, this review suggested an example of a resource index containing existing, published psychological theories and variables that are associated to positive mental health outcomes. This example resource index was proposed within a framework based on the physical fitness analogy of strength, endurance and flexibility. Following on from the conceptual review, a Delphi study was conducted to engage an international expert panel (n = 25) to evaluate the proposed definition and four guiding principles of mental fitness, expert consensus was achieved.
Results provided an updated definition of mental fitness as being “the modifiable capacity to utilise resources and skills to flexibly adapt to challenges or advantages, enabling thriving”. Results for the four guiding principles were (1) fitness is a positive term without connotations of illness implied by mental health or mental illness; (2) mental fitness could be understood by the wider community in a similar way to physical fitness; (3) mental fitness is measurable; and (4) mental fitness can be improved, in a similar way to physical fitness. The panel also offered valuable, qualitative input and recommendations for future research and practice. The final study was conducted to provide preliminary empirical support for the concept and CONCEPTUALISING AND MEASURING MENTAL FITNESS 10 measurement of mental fitness.
Exploratory (EFA) and confirmatory (CFA) factor analysis (n = 223) was used to analyse items from a selection of variables drawn from established measures. Results from the EFA identified four factors labelled strength, endurance, flexibility, and team supporting the item content and the physical fitness analogy. Results from the CFA provided preliminary evidence for a multifactorial model of mental fitness and validation for the four factors. Moreover, results provided initial validation for a mental fitness model containing the four factors subsumed by a second order factor of mental fitness.
Limitations and future directions are discussed, as are the broader theoretical and empirical implications of the research. The preliminary findings suggest that the concept and model of mental fitness can provide a new and positive approach to the language and measurement of positive mental health aligned to the physical fitness analogy. This can create a broader understanding that, as in physical fitness, mental fitness requires the practice of intentional activities to create positive habits of mind that lead to higher levels of well-being, optimal functioning and quality of life outcomes. CONCEPTUALISING AND MEASURING MENTAL FITNESS 11 CHAPTER 1 – INTRODUCTION A vision for the future: Listen in on this conversation… “How’s your fitness regime going?” “Right now I’m working on building my biceps and improving my mood”.
“Is it working?” “Yes, my muscles are bigger and my brain is giving me more automatic positive thoughts now, so I have much more energy”. Rationale The overarching objective of this dissertation is to develop the concept of mental fitness to provide a contribution to theory, the development of research propositions and practical interventions. To date the concept of mental fitness has no consistent theoretical foundations, construct validity or standardised measurement to research, replicate or for practitioners’ to apply. The essential premise is that the concept of mental fitness will assist psychologists, mental health professionals, medical practitioners, organisations, the wider community, policy makers and governments meet the challenge of reducing mental illness and improving mental health.
It is proposed that the language of fitness is effective in the mental health context because (a) it utilises language already known and understood and is easy to relate to; (b) it reduces stigma that exists around the concept of mental health; (c) it helps to address the need for more proactive, preventative and holistic approaches to improved mental health that has consumer acceptability; (d) it progresses the idea that a fit mind and body are equally important and need regular, intentional activities and practices to build sustainable habits of mind. It is argued that the concept of mental fitness, offered in a similar framework to physical fitness, can provide a way of explaining positive mental health theory, research and activities in a non-threatening and proactive way so as to increase mental health outcomes. CONCEPTUALISING AND MEASURING MENTAL FITNESS 12 Research Questions To commence this process, the primary research questions for this dissertation are: (1) what is mental fitness and how should it be defined? (2) what are the components of mental fitness? and (3) what are the factors underlying current published measures, that can be used to operationalise mental fitness?
