Psychology - Abstract
Cancer diagnosis and treatment are a stressful experience for a patient of any age. However, compared to younger children or adults, adolescents and young adults (AYA) are a distinct group of patients with unique challenges due to their developmental period. Literature suggests that up to a third of AYA patients may be at risk for developing psychopathology. While there is an increasing interest in studying psychosocial outcomes in AYAs, little is understood about the mechanisms of psychosocial wellbeing in this population. This thesis uses a variety of research methods to examine factors associated with resilience and psychopathology in youth living with cancer and beyond cancer and aims to identify intervention targets to promote holistic recovery of young people with cancer. Because psychosocial oncology is a young and rapidly evolving field, I begin by a short overview of some of the methodological challenges I faced in my research. In particular, I wanted to address the issue of not using cancer-specific questionnaires, and lack of longitudinal and data-driven approaches. To this end, I have innovatively used a mixed-methods approach to explore how individual, as well as socio-environmental factors are associated with psychological outcomes in young patients and survivors. I begin by a systematic review of the literature, which provides an insight into the prevalence rates of psychopathology and identifies some of the risk factors for psychiatric disorders. Subsequently, I present qualitative analysis of in-depth interviews about life with and beyond cancer. For my third study, I developed an online survey to collect information about psychological wellbeing, including cancer-specific questionnaires. Using this data, I employed network analysis to explore if any symptoms of psychopathology and cancer worries are particularly salient and contribute more to the overall symptomatology than the rest. Lastly, I conclude with a longitudinal analysis of a clinical dataset in Canada, where I explored psychological wellbeing and its relationship with fatigue, a commonly endorsed symptom. Due to the global pandemic COVID-19 and its consequent disruption, I complemented my online survey with an auxiliary study that explored the impact of the pandemic on the wellbeing of young people with cancer who were considered at risk for infections. Together, the research presented in this thesis contributes evidence to support that a subset of young people with cancer report psychopathology, and those at risk may be particularly vulnerable in the times of distress, such as the global pandemic. However, psychopathology may result from vastly different, individually led modifiable pathways, which can be addressed with a more personalized approach to care in the future. Psychosocial adaptation to cancer in young people is a complex process with many factors at play. This thesis begins to uncover a few, introduces innovative methods to counteract the existing mythological pitfalls and concludes by proposing future directions for strengthening research in psychosocial oncology and reducing the inequalities of outcomes in young people with cancer.

Background: Adolescent cancer survivors are a particularly vulnerable group of young patients. Compared with healthy peers, adolescent survivors face more psychosocial difficulties and are at increased risk of developing psychiatric disorders. Aims: We aimed to establish prevalence rates and predictors of psychiatric disorders in young cancer survivors and discuss areas for targeted interventions. Method: We systematically reviewed four major online databases: Embase, PsychINFO, Scopus, and Medline for quantitative studies evaluating mental health in adolescent cancer survivors. We used a narrative synthesis approach. Results: Nineteen studies met our inclusion criteria. Across the sample, up to 34% met criteria for post‐traumatic stress disorder (PTSD), 13% for clinical depression, and 8% for anxiety. Maladaptive coping, illness relapse, higher number of late effects, brain tumor diagnosis, and poor family functioning and parental distress were associated with higher psychological distress. Conclusions: A significant subset of adolescent survivors reports PTSD, anxiety, and depression symptoms. Individuals who present with more vulnerabilities and higher risk indices should be routinely assessed in order to reduce the psychological, social, and economic burden associated with poor mental health in this population. Early prevention strategies should target maladaptive coping mechanisms and promote healthy peer relationships and family functioning.

- Abstract
Background: The Common-Sense Model of illness self-regulation underpins illness-specific cognitions (including both illness perceptions and a fear of cancer recurrence; FCR). There is evidence in adults of associations between FCR, illness perceptions, and mental health in adult cancer survivors. However, there is limited empirical research examining these constructs within the developmentally distinct population of adolescent and young adult (AYA) survivors of cancer. The current study aimed to bridge that gap to inform potentially modifiable treatment targets in this population. Method: A cross-sectional, correlational design was used to examine the associations between illness perceptions, FCR, and mental health. A web-based survey was completed by a convenience sample of AYA survivors. Regression and mediation analyses were performed. Results: Overall, more negative illness perceptions were associated with more severe FCR and greater depressive and anxiety symptomatology. Higher FCR was predictive of worse overall mental health. More negative overall illness perceptions predicted the relationship between FCR-depression, mediating 24.1% of the variance. Contrastingly, overall illness perceptions did not predict or mediate the relationship between FCR-anxiety. However, the specific illness perceptions regarding timeline, personal control, and emotional representation, were predictive of the FCR-anxiety relationship. Discussion: Illness perceptions and FCR were predictive of mental health outcomes. Identifying and therapeutically targeting negative illness perceptions in those young adults who have survived adolescent cancer could therefore be a means of reducing anxiety and depressive symptomatology. Limitations and future directions are discussed., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objectives: This study explored factors that play a role in psychological adaptation and recovery of young people with sarcoma., Design: Qualitative study., Setting: National Health Service hospitals in the UK., Methods: Using purposive sampling, participants were recruited for semistructured interviews over the telephone or face to face in order to answer questions about how cancer impacted various domains of their life. Data were analysed using a framework approach., Results: Thirty participants, aged 15-39 years with primary sarcoma diagnosis provided in-depth accounts of their experience. Emerging themes from the interviews were grouped into two overarching themes that relate to one's adaptation to illness: individual level and environmental level. The qualitative nature of our study sheds light on meaningful connections between various factors and their role in one's psychological adaptation to sarcoma. We devised a visual matrix to illustrate how risk and protective factors in adaptation vary between and within individuals., Conclusions: This study demonstrates that young people with sarcoma report an array of both positive and negative factors related to their illness experience. The route to recovery is a multifactorial process and a one-size-fits-all approach to psychosocial care proves inadequate. We propose that moving beyond the latent constructs of resilience and psychopathology towards a dynamic model of psychological adaptation and recovery in this population can result in optimisation of care. We offer some recommendations for professionals working with young people with sarcoma in clinic and research., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

- Abstract
This cross sectional pilot study assesses the feasibility of conducting online research into cognitive mechanisms in adolescent and young adult cancer populations. Twenty-one participants, aged 18-39 years, answered questionnaires about mental defeat, rumination, cancer worry, anxiety, and experience participating in such research. Seven participants scored in the clinical range for anxiety. Cancer-related worry was common. Rumination and mental defeat were positively associated with anxiety. The participants reported the length and type of questions to be appropriate and not distressing. Findings may inform future research into cognitive mechanisms, which could aid the development of psychosocial interventions for young cancer patients.

- Abstract
Aim: To compare the differences of glucose metabolism outcomes between treatment-naïve, patients with first episode psychosis (FEP) and mood disorders., Methods: We conducted a systematic review and meta-analysis of glucose intolerance in treatment-naïve, first episode patients with severe mental illnesses (SMIs)., Results: We identified 31 eligible studies. Compared to healthy controls, FEP group have higher insulin and insulin resistance levels, and both groups have higher glucose tolerance test results. No significant differences were found in glucose metabolism outcomes between FEP and mood disorder groups., Conclusions: Our results highlight impaired glucose metabolism at the onset of SMIs, suggesting both patients with psychosis and mood disorders are high-risk groups for diabetes development., (© 2018 John Wiley & Sons Australia, Ltd.)

- Abstract
Aims: (1) Determine the accuracy of self-reported height, weight, and body mass index (BMI) calculated from those values in a population suffering from both serious mental illness (SMI) and overweight/obesity; (2) identify any associations that may predict error in self-reported measurements. Data were collected from screening appointments for two clinical trials for adult patients with SMI and overweight/obesity (BMI > 28) who gained weight while on antipsychotic medications. Both studies were conducted at the same urban community mental health center. Differences in self-reported and measured height, weight, and BMI were calculated. Analysis included age, sex, race, psychiatric diagnosis, and level of education. BMI calculated from self-reported height and weight were significantly lower (-0.47kg/m
2 ) than measured values. Height was significantly overestimated (1.04cm), while weight was underestimated (0.055kg). Men underestimated BMI more than women (0.55 vs. 0.41kg/m2 ). Increasing age correlated with lower accuracy of self-reported height and BMI. No differences due to psychiatric diagnosis, race, or education were found. BMI calculated from self-reported height and weight from patients with SMI and overweight/obesity is as accurate as the self-reported measurements collected from the general population and, while measurement is best, self-reports can be used as a tool for screening for obesity., (Copyright © 2017 Elsevier B.V.

- Abstract
Aim: To compare the prevalence of diabetes in patients with schizophrenia treated at a community mental health center with controls in the same metropolitan area and to examine the effect of antipsychotic exposure on diabetes prevalence in schizophrenia patients., Methods: The study was a comprehensive chart review of psychiatric notes of patients with schizophrenia and schizoaffective disorder treated at a psychosis program in a community mental health center. Data collected included psychiatric diagnoses, diabetes mellitus diagnosis, medications, allergies, primary care status, height, weight, body mass index (BMI), substance use and mental status exam. Local population data was downloaded from the Centers for Disease Control Behavioral Risk Factor Surveillance System. Statistical methods used were χ
2 test, Student's t test, general linear model procedure and binary logistic regression analysis., Results: The study sample included 326 patients with schizophrenia and 1899 subjects in the population control group. Demographic data showed control group was on average 7.6 years older ( P = 0.000), more Caucasians (78.7% vs 38.3%, P = 0.000), and lower percentage of males (40.7% vs 58.3%, P = 0.000). Patients with schizophrenia had a higher average BMI than the subjects in the population control (32.11, SD = 7.72 vs 27.62, SD = 5.93, P = 0.000). Patients with schizophrenia had a significantly higher percentage of obesity (58.5% vs 27%, P = 0.000) than the population group. The patients with schizophrenia also had a much higher rate of diabetes compared to population control (23.9% vs 12.2%, P = 0.000). After controlling for age sex, and race, having schizophrenia was still associated with increased risk for both obesity (OR = 3.25, P = 0.000) and diabetes (OR = 2.42, P = 0.000). The increased risk for diabetes remained even after controlling for obesity (OR = 1.82, P = 0.001). There was no difference in the distribution of antipsychotic dosage, second generation antipsychotic use or multiple antipsychotic use within different BMI categories or with diabetes status in the schizophrenia group., Conclusion: This study demonstrates the high prevalence of obesity and diabetes in schizophrenia patients and indicates that antipsychotics may not be the only contributor to this risk., Competing Interests: Conflict-of-interest statement: None of the authors have any conflict of interest to report.- Published
