RESUMO
OBJECTIVES: The trauma and social pathways model of psychosis proposes interactions between trauma, attachment, social rank and dissociation in pathways to psychosis, though this model has yet to be empirically investigated. The primary aim of this study was to examine the overall predictive value of the trauma and social pathways model using regression analysis. A secondary aim was to delineate hypothesized pathways between trauma and positive symptoms of psychosis using serial mediation analysis. METHOD: This was a cross-sectional study of people attending mental health services for a psychosis-related diagnosis (N = 71). Measures of trauma, positive symptoms of psychosis, attachment, social comparison and dissociation were completed. RESULTS: A model of recurrent trauma, insecure attachment, social rank and dissociation predicted 23.2% of the variance in positive symptoms of psychosis. Recurrent trauma, attachment and dissociation contributed significantly to the model, while social rank did not. Further, serial mediation analysis indicated that the sequence of disorganized attachment and dissociation fully mediated the relationship between recurrent trauma and positive symptoms. CONCLUSIONS: Results provide preliminary support for the trauma and social pathways model of psychosis, specifically as it relates to recurrent trauma, insecure attachment and dissociation. Results did not support the social rank component of this model, however. These findings provide clear targets for the development of next-wave psychological interventions that focus on trauma-related variables in psychosis. Future studies should replicate these findings with a larger clinical sample, and consider a measure of shame to further elucidate social processes in pathways to psychosis.
RESUMO
AIM: Early intervention for people experiencing first episode psychosis is a priority, and keyworkers are vital to such services. However, keyworkers' roles in addressing first episode psychosis patients' physical health are under researched. This study addresses this knowledge gap by evaluating a keyworker-mediated intervention promoting physical health among first episode psychosis patients. METHODS: The study was informed by the Medical Research Council's Framework for Complex Interventions to Improve Health. First episode psychosis participants were recruited from three Irish mental health services. The intervention was evaluated in terms of its feasibility/acceptability. RESULTS: Feasibility outcomes were mixed (recruitment rate = 24/68 [35.3%]; retention rate = 18/24 [75%]). The baseline sample was predominantly male (M:F ratio = 13:6; Med age = 25 y; IQR = 23-42 y). Common health issues among participants included overweightness/obesity (n = 11) and substance use (smoking/alcohol consumption [n = 19]). Participants' initial health priorities included exercising more (n = 10), improving diet (n = 6), weight loss (n = 7) and using various health/healthcare services. The intervention's acceptability was evidenced by the appreciation participants had for physical health keyworkers' support, as well as the healthy lifestyle, which the intervention promoted. Acceptability was somewhat compromised by a low-recruitment rate, variable linkages between keyworkers and general practitioners (GPs) and COVID-19 restrictions. CONCLUSIONS: Physical health-oriented keyworker interventions for first episode psychosis patients show promise and further evaluation of such initiatives is warranted. Future interventions should be mindful of participant recruitment challenges, strategies to enhance relationships between keyworkers and GPs, and if necessary, they should mitigate COVID-19 restrictions' impacts on care.
