Depression and anxiety symptoms in young adults before and during the COVID-19 pandemic: evidence from a Canadian population-based cohort.

BACKGROUND: Concerns have been raised that the COVID-19 pandemic could increase risk for adverse mental health outcomes, especially in young adults, a vulnerable age group. We investigated changes in depression and anxiety symptoms (overall and severe) from before to during the pandemic, as well as whether these changes are linked to COVID-19-related stressors and pre-existing vulnerabilities in young adults followed in the context of a population-based cohort. METHOD: Participants (n = 1039) from the Quebec Longitudinal Study of Child Development reported on their depression (Centre for Epidemiological Studies Depression Scale, short form) and anxiety (General Anxiety Disorder-7 Scale) symptoms and completed a COVID-19 questionnaire during the first wave of the COVID-19 pandemic in the summer of 2020 (age 22 years). Assessments at age 20 (2018) were used to estimate pre-pandemic depression and anxiety symptom severity. RESULTS: While mean levels of depression and anxiety symptoms did not change from before to during the first wave of the COVID-19 pandemic (e.g., the mean of depressive symptoms was 9.30 in 2018 and 9.59 in 2020), we observed a slight increase in rates of severe depression (scores ≥ 21) from before (6.1%) to during (8.2%) the pandemic. Most COVID-19-related variables (e.g., loss of education/occupation, frequent news-seeking) - except living alone - and most pre-existing vulnerabilities (e.g., low SES, low social support) were not associated with changes in depression or anxiety symptoms. However, results varied as a function of pre-pandemic levels of depression and anxiety: depression and anxiety symptoms increased among adults with the lowest levels of symptoms before the pandemic, while they decreased among those with the highest levels of symptoms, possibly reflecting a regression to the mean. CONCLUSIONS: Depression and anxiety symptoms in young adults from Québec in Summer 2020 were mostly comparable to symptoms reported in 2018. Most COVID-19-related stressors and pre-existing vulnerabilities were not associated with changes in symptoms, except living alone and pre-existing symptoms of depression and anxiety. However, the increased rate of severe depression warrants further investigation.

The Quality of Six Clinical Practice Guidelines in Health and Social Sciences: Are We on the Right Track?

Interest in the development and promotion of clinical practice guidelines (CPGs) continues to grow in many professions. However, the potential benefits associated with CPGs are dependent upon their quality. A number of studies have shown that the quality of CPGs varies greatly. Furthermore, the quality of many of the CPGs used in health and social sciences has yet to be examined. In light of this, the aim of this study was to examine the quality of CPGs that focus on intervention and care management in mental health in Quebec. A search of Quebec regulatory bodies websites was conducted and six CPGs were included in this study. The CPGs were assessed by four trained raters using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. Items scores and domains scores were considered to determine the quality of the six CPGs. Results show that many of the CPGs did not achieve minimum ratings for numerous quality checks. Notably, none of the CPGs were designed using a rigorous methodology, they lacked transparency throughout the development process and insufficient consideration was given to the applicability of the recommendations they included. Because these shortcomings may hinder the efficacy and utilization of CPGs, suggestions to improve the development of CPGs and to improve their quality are discussed.

The effects of walking in nature on negative and positive affect in adult psychiatric outpatients with major depressive disorder: A randomized-controlled study.

BACKGROUND: While walking in nature has been shown to improve affect in adults from the community to a greater extent than walking in urban settings, it is unknown whether such benefits apply to individuals suffering from depression. Using a parallel group design, this randomized controlled trial examined the effects of a single walk in nature versus urban settings on negative and positive affect in adult psychiatric outpatients diagnosed with major depressive disorder (MDD). METHOD: Participants recruited from a psychiatric outpatient clinic for adults with MDD were randomly assigned to a nature or urban walk condition. Thirty-seven adults (mean age = 49 years) completed a single 60-minute walk. Negative and positive affect were assessed using The Positive and Negative Affect Schedule or PANAS at 6 time points: before the walk, halfway during the walk, immediately post-walk, at home before bedtime, 24 h post-walk, and 48 h post-walk. RESULTS: Controlling for baseline levels of affect before the walk, individuals who walked in nature experienced overall lower levels of negative affect, F(1, 35.039) = 4.239, p = .047, compared to those who walked in urban settings. Positive affect did not differ across walk conditions. LIMITATIONS: The generalizability of results are limited by the small sample size and the presence of more female than male participants. CONCLUSIONS: Walking in nature might be a useful strategy to improve negative affect in adults with MDD. Future research should investigate different ways to integrate the beneficial effects of nature exposure into existing treatment plans for psychiatric outpatients with MDD.

Assessing the quality of seven clinical practice guidelines from four professional regulatory bodies in Quebec: What's the verdict?

RATIONALE, AIMS, AND OBJECTIVES: Clinical practice guidelines (CPGs) have become a common feature in the health and social care fields, as they promote evidence-based practice and aim to improve quality of care and patient outcome. However, the benefits of the recommendations reported in CPGs are only as good as the quality of the CPGs themselves. Indeed, rigorous development and strategies for reporting are significant precursors to successful implementation of the recommendations that are proposed. Unfortunately, research has demonstrated that there is much variability in their level of quality. Furthermore, the quality of many CPGs has yet to be examined. The aim of the present study was to assess the quality of seven CPGs from four Quebec professional regulatory bodies pertaining to clinical evaluations in the fields of medicine, psychoeducation, psychotherapy, and social work. METHODS: The seven Quebec CPGs were assessed by four trained appraisers using the Appraisal of Guidelines for Research and Evaluation II guideline evaluation tool. RESULTS: Results suggest that while some quality criteria were met, most were not, denoting that these CPGs are of sub-optimal quality. CONCLUSION: Our findings highlight that there is still a lot to be done in order to improve the rigour and transparency with which scientific evidence is assessed and applied when developing CPGs. Impacts regarding the implementation of these CPGs are discussed in light of their use in clinical practice.
