    “An Incredible Amount of Stress before You Even Put a Shovel in the Ground”: A Mixed Methods Analysis of Farming Stressors in Canada

    by Rochelle Thompson, Briana N. M. Hagen, Margaret N. Lumley, Charlotte B. Winder, Basem Gohar, Andria Jones-Bitton

    Farming is widely regarded as a highly stressful occupation, and many farming stressors have been studied globally. Research on farming stressors in Canada is scarce, yet there is some indication that Canadian farmers have high perceived stress scores and score more severely across mental health outcomes compared to the general population. This study provides a comprehensive exploration of farming stressors in Canada with the aim to inform avenues to reduce stress and/or boost the well-being of farmers. An exploratory sequential mixed-methods design was used. First, qualitative data were collected from 75 in-depth interviews with farmers and industry professionals from Ontario, Canada from 2017 to 2018. These data were then used to inform items measuring self-reported stress across 12 farming stressors in a national cross-sectional survey of farmers’ mental health conducted February–May 2021. Results from both data sources provide an initial understanding of the episodic and chronic stressors faced by farmers in Canada, and the context within which these stressors are experienced. Implications and focus areas for stress reduction and well-being promotion are discussed in this paper.

    Mental Health and Substance Use of Farmers in Canada during COVID-19

    by Rochelle Thompson, Briana N. M. Hagen, Margaret N. Lumley, Charlotte B. Winder, Basem Gohar, Andria Jones-Bitton

    Farmers in Canada faced higher levels of mental distress than the general public prior to the Coronavirus Disease 2019 (COVID-19) pandemic and are generally less likely than the public to seek help. However, the mental health impacts of COVID-19 on farmers in Canada remain unexplored. Our objective was to investigate mental health outcomes among farmers in Canada by gender and within the context of COVID-19. We conducted a national, online, cross-sectional survey of farmers in Canada (February–May 2021). The survey included validated scales of anxiety, depression, perceived stress, burnout (emotional exhaustion, cynicism, professional efficacy), alcohol use, resilience, and questions regarding participants’ perceived changes in these outcomes during the pandemic. Data were also collected on the impact of COVID-19 specific social and economic factors on mental health, help-seeking, and sense of community belonging through the pandemic. Descriptive statistics were summarized, and Chi-square analyses and t-tests were conducted to compare survey results between genders and to data collected in our similar 2016 survey and normative population data. A total of 1167 farmers participated in the survey. Participants scored more severely across scales than scale norms and the general Canadian population during COVID-19. Scale means were consistent between the 2016 and 2021 samples. Most participants with moderate to severe scores for any outcome reported worsening symptoms since the pandemic began. Women fared significantly worse than men across measures. Over twice as many women reported seeking mental health or substance use support during the pandemic than men. Participants rated the mental health impacts of all social and economic factors related to COVID-19 examined significantly (p < 0.05) differently than the Canadian public. The pandemic has negatively impacted the mental health of farmers in Canada and in ways that differ from the general population. National level and gender-specific mental health supports are needed to help improve the mental health of farmers in Canada.

  • Sources of Emotional Maltreatment and the Differential Development of Unconditional and Conditional Schemas

    by Molly C. McCarthy, Margaret N. Lumley

    Schema theory posits that experiences of maltreatment result in the early development of maladaptive schemas (EMS; Young, Klosko, & Weishaar, 2003, Schema therapy: A practitioner's guide, The Guilford Press: New York, NY). EMS are organized by conditionality; unconditional schemas are theorized to develop early in childhood predominantly in response to experiences of parenting and conditional schemas are theorized to develop later in life in response to other relationships. Despite this distinction, minimal previous research has investigated their differential development. The current study examined the relative contributions of parental and other (peer and intimate partner) emotional maltreatment (EMT) in the differential development of unconditional and conditional schemas. Ninety-seven undergraduate students retrospectively reported their maltreatment experiences using the Lifetime Experiences Questionnaire and completed the Young Schema Questionnaire to measure EMS. Consistent with hypotheses, parental EMT was the strongest predictor of unconditional schemas. Unexpectedly, parental EMT also emerged as the strongest predictor of conditional schemas. Theoretical and clinical implications of these findings are discussed.


  • Stress Generation in Adolescent Depression: The Moderating Role of Child Abuse and Neglect

    by Kate L. Harkness, Margaret N. Lumley, Alanna E. Truss

    The present study examined the role of childhood abuse and neglect and depression recurrence in moderating the generation of stressful life events in adolescent depression. Maltreatment history and stressful life events were assessed using two rigorous contextual interviews and rating systems. In a sample of 59 community depressed adolescents we found significantly higher rates of interpersonal events in the 3-month period immediately following depression episode onset versus the 3-month period immediately preceding onset in adolescents with a history of childhood maltreatment. By contrast, rates of events remained constant over a matched period in a control group of non-maltreated adolescents. Furthermore, the generation of interpersonal events only held among those on a first onset of depression. These results suggest that a history of childhood abuse and neglect exacerbates the psychosocial dysfunction associated with the onset of depression, particularly in the very first episode.
