Walking Alongside
Medical assistance in dying (MAiD) was introduced into Canadian federal legislation in 2016. Mental illness as the sole underlying medical condition (MI-SUMC) is currently excluded from eligibility; such exclusion is scheduled to expire on March 17, 2024. Irremediability, capacity, quality of life, autonomy, family involvement, and healthcare system constraints have been debated intensively. Recent studies have not explored the views of family me…
A qualitative exploration of the lived experiences of Body Dysmorphic Disorder
Body Dysmorphic Disorder (BDD) is characterized by an intense preoccupation with one or more perceived "defects" in physical appearance. Despite the distress and impairment associated with BDD, the disorder remains understudied and poorly understood. In particular, there are limited studies available which give voice to those with firsthand experiences of the disorder. A qualitative approach was employed to study lived experience of BDD. In-depth…
Psychedelics As Psychiatric Medications
Searching for relief from suffering
Medical assistance in dying (MAiD) was introduced into Canadian legislation in 2016. Mental illness as the sole underlying medical condition (MI-SUMC) is excluded from eligibility; this is expected to change in 2024. Incurability, intolerable suffering, capacity to make healthcare decisions, and suicidality have been publicly debated in connection with mental illness. Few studies have explored the views of persons with mental illness on the intro…

People experiencing homelessness (PEH) have high rates of acute and chronic health conditions, complex support needs and often face multiple barriers to accessing health services. Financial incentive (FI) interventions have been found effective in improving service engagement and health outcomes for a range of health conditions, populations and settings, but little is known about their impact on PEH. We conducted a scoping review to explore the i…
The relationship between physical activity levels and symptoms of depression, anxiety and stress in individuals with alopecia Areata
81.9% of the participants did not meet PA guidelines. Participants with hair loss of more than 50% on the scalp, and who did not meet PA guidelines, were significantly more likely to experience symptoms of severe depression (p = .003), moderate anxiety (p = .04) and mild stress (p = .003) than those who met guidelines CONCLUSION: Findings suggest that increased PA participation in AA individuals with severe hair loss is associated with improved m…
Psychosocial Factors Affecting Smoking Cessation Among People Living With Schizophrenia
Introduction: People living with schizophrenia smoke at much higher rates than the general population, and find it more difficult to quit. To date, lived experience has received little attention from researchers. Personal recovery perspectives may generate further insights into established psychosocial barriers and enablers of smoking cessation. Methods and Results: A lived experience account is provided by one of our authors that places the curr…
Quitlink”—A Randomized Controlled Trial of Peer Worker Facilitated Quitline Support for Smokers Receiving Mental Health Services
Introduction: Although smokers with severe mental illnesses (SSMI) make quit attempts at comparable levels to other smokers, fewer are successful in achieving smoking cessation. Specialized smoking cessation treatments targeting their needs can be effective but have not been widely disseminated. Telephone delivered interventions, including by quitlines, show promise. However, few SSMI contact quitlines and few are referred to them by health profe…
Protocol for an Economic Evaluation of the Quitlink Randomized Controlled Trial for Accessible Smoking Cessation Support for People With Severe Mental Illness
Introduction: Smoking is a major cause of disease burden and reduced quality of life for people with severe mental illness (SMI). It places significant resource pressure on health systems and financial stress on smokers with SMI (SSMI). Telephone-based smoking cessation interventions have been shown to be cost effective in general populations. However, evidence suggests that SSMI are less likely to be referred to quitlines, and little is known ab…
Latent Psychotic Symptom Profiles Amongst People Who Use Methamphetamine
The inability to distinguish clearly between methamphetamine-related psychosis and schizophrenia has led to the suggestion that "methamphetamine psychosis" does not represent a distinct diagnostic entity but rather that the drug has triggered a vulnerability to schizophrenia. We tested this possibility by exploring the latent class structure of psychotic symptoms amongst people who use the drug and examining how these latent symptom profiles corr…
Reducing Smoking Among People With Schizophrenia
Although tobacco smoking is very common among people with schizophrenia and has devastating effects on health, strategies to ameliorate the risk are lacking. Some studies have reported promising results yet quit rates are much lower than in the general population. There is a need to advance research into smoking cessation efforts among people with schizophrenia. We posed the following question to five leading international experts in the field: "…

Relative strength of the associations of body fat, muscularity, height, and penis size dissatisfaction with psychological quality of life impairment among sexual minority men
To date, there is scant research on whether different domains of male body dissatisfaction vary in the strengthof their relationships with psychological well-being. This paucity also extends to sexual minority men (i.e.,men who report their sexual orientation as gay or bisexual). Thus, among sexual minority men, we examinedthe relative strength of the associations of four key male body dissatisfaction domains body fat, muscularity,height, and pen…

"I don't eat a hamburger and large chips every day!" A qualitative study of the impact of public health messages about obesity on obese adults
This study is the first step in exploring the ways in which we understand how public health messages about obesity resonate with obese individuals in Australia. However, much more research--both qualitative and quantitative--is needed to enhance understanding of the impact of obesity messages on individuals
‘Our girth is plain to see’
The news media plays an important role in making visible and shaping public understandings of health and health risks. In relation to overweight and obesity, it has been suggested that the media is more likely to engage in alarmist reporting in a climate in which it is taken for granted that obesity is an ‘epidemic’. This study analyses Australian media coverage of a report on overweight and obesity, Australia's Future ‘Fat Bomb’: a report on the…

Criminally violent victimisation in schizophrenia spectrum disorders
Overall, our findings suggest that substance abuse (particularly drug abuse) is a key predictor of violent victimisation based on criminal statistics. The latter has implications for mental health professions involved in the care planning and community management of patients with major mental illness and work points to the importance of substance abuse treatment in the prevention of victimisation as well as violence perpetration

A comparative study of the economic and social functioning of Vietnamese-Australians with low English proficiency living with psychotic illness
BACKGROUND: Because national surveys of people living with psychotic disorders tend to exclude people with low English proficiency (LEP), little is known of their economic and social functioning. Culturally influenced explanatory models may result in delayed presentation and poorer functioning. AIMS: The study aimed to compare the functioning of LEP Vietnamese-Australian and Australian-born patients with psychosis and to investigate the Vietnames…

This pilot study aimed to determine whether CR enhances vocational outcomes for job seekers participating in an innovative vocationally oriented psycho‐educational …
A randomised controlled trial of dietary improvement for adults with major depression (the ‘SMILES’ trial)
The possible therapeutic impact of dietary changes on existing mental illness is largely unknown. Using a randomised controlled trial design, we aimed to investigate the efficacy of a dietary improvement program for the treatment of major depressive episodes. ‘SMILES’ was a 12-week, parallel-group, single blind, randomised controlled trial of an adjunctive dietary intervention in the treatment of moderate to severe depression. The intervention co…
Managing the transition to open access publishing
To manage the transition to the open access (OA) model of scholarly publishing, we need to understand better what enables, encourages and inhibits the adoption of OA publishing among scientists, and to appreciate individual differences within disciplines. The study adopts a psychological perspective to elucidate motivations, capabilities and opportunities for OA publishing among bioscientists in the UK. To identify differences within the discipli…
