A digital iCBT intervention for social anxiety disorder in Quebec and Ontario: protocol for a multi-phase effectiveness-implementation study.

BACKGROUND: Social anxiety disorder (SAD) is one of the most prevalent anxiety disorders in Canada. Viable therapy options for the treatment of SAD include CBT being delivered virtually. In Australia, an innovative internet-delivered cognitive-behavioral therapy (iCBT) program for social anxiety has been developed, implemented, and demonstrated as effective. To make available high-quality and real-time evidence in response to the crucial need to access psychological services to meet population mental health needs, we propose to conduct a Canadian adaptation of the iCBT Shyness Program and to examine the program's effectiveness, and implementation in two Canadian provinces (Quebec and Ontario). METHODS: The overall study design is a hybrid effectiveness-implementation study of a quasi-experimental parallel group trial. Prior to implementing the iCBT Shyness Program, it will undergo an initial adaptation to the Canadian context and focus groups will be conducted with key actor groups to discuss the adaptations to the graphics, narration of the lessons, and this to better reflect varying socio-cultural context among Canadian French- and English-speaking populations. We will evaluate the effectiveness of the program in three parallel pathways reflecting real-world pathways: (1) self-refer to the intervention; (2) recommended by a health professional without guidance; and (3) recommended by a health professional, with low-intensity guidance. Data collection will be carried out at baseline, at the beginning of each lesson, 12-week and 6-month follow-up. Outcomes measured will include anxiety and depressive symptoms, psychological distress, disability, as well as health service utilization and satisfaction. Semi-structured interviews will then be conducted with study participants and health care providers to explore facilitating factors and barriers to the implementation of the iCBT adapted program. DISCUSSION: This study will provide evidence on the effectiveness, barriers and facilitating factors to implementing a low-intensity iCBT in the Canadian context for SAD, which will bridge an important care gap for undeserved populations in Canada with SAD. Findings will inform the eventual scaling up of the program in community-based primary care across Canada. This would improve equity of the health care system by helping a large number of Canadians to timely access to mental health services. TRIAL REGISTRATION: clinicaltrials.gov NCT06403995.

Care trajectories and transitions at the end of life: a population-based cohort study.

BACKGROUND: End-of-life periods are often characterised by suboptimal healthcare use (HCU) patterns in persons aged 65 years and older, with negative effects on health and quality of life. Understanding care trajectories (CTs) and transitions in this period can highlight potential areas of improvement, a subject yet only little studied. OBJECTIVE: To propose a typology of CTs, including care transitions, for older individuals in the 2 years preceding death. DESIGN: Retrospective cohort study. METHODS: We used multidimensional state sequence analysis and data from the Care Trajectories-Enriched Data (TorSaDE) cohort, a linkage between a Canadian health survey and Quebec health administrative data. RESULTS: In total, 2080 decedents were categorised into five CT groups. Group 1 demonstrated low HCU until the last few months, whilst group 2 showed low HCU over the first year, followed by a steady increase. A gradual increase over the 2 years was observed for groups 3 and 4, though more pronounced towards the end for group 3. A persistent high HCU was observed for group 5. Groups 2 and 4 had higher proportions of cancer diagnoses and palliative care, as opposed to comorbidities and dementia for groups 3 and 5. Overall, 68.4% of individuals died in a hospital, whilst 27% received palliative care there. Care transitions increased rapidly towards the end, most notably in the last 2 weeks. CONCLUSION: This study provides an understanding of the variability of CTs in the last two years of life, including place of death, a critical step towards quality improvement.

Long-term effects of benzodiazepine discontinuation among older adults: potential improvements on depressive symptoms.

OBJECTIVES: To examine how change in benzodiazepine (BZD) use is linked to changes in depressive symptoms intensity, worry intensity, and sleep quality over 16 months. METHOD: Data come from a larger randomised controlled trial (RCT) named the 'Programme d'Aide du Succès au SEvrage (PASSE-60+)' study (NCT02281175). Seventy-three participants age 60 years and older took part in a 4-month discontinuation programme and were assessed four times over 16 months. Change in BZD use was defined as the difference in reported mg/day between two assessments. Control variables were RCT discontinuation group; BZD use at T1; and either depressive symptoms, worry intensity, or sleep quality at T1. Hierarchical multiple regressions were used to analyse data. RESULTS: In the short term, right after the discontinuation programme, sleep quality worsened with lower BZD use. This link was no longer significant at the 3- and 12-month follow-up. In the long term, depressive symptoms lowered with lower BZD use. No change was found in worry intensity in relation to BZD use at all measurement times. CONCLUSION: Discontinuation may improve depressive symptoms. Our study also questions the long-term effectiveness of BZD use, since long-term discontinuation was not linked with change in worry intensity and sleep quality.

Factors associated with mental health service use during the pandemic: Initiation and barriers.

BACKGROUND: Scarce are the studies focusing on initiation of new mental health service use (MHSU) and distinguishing individuals who have sought services but have been unsuccessful in accessing these. AIMS: Assessing the factors associated with initiating new MHSU as compared to no MHSU due to self-reported no need, no MHSU due to health system and personal barriers and MHSU using resources already in place. METHODS: The sample included participants (n = 16,435) in the five established regional cohorts of the Canadian Partnership for Tomorrow's Health (CanPath) who responded to the CanPath COVID-19 health surveys (May-December 2020 and January-June 2021). Multinomial regression analyses were carried out to study MHSU since the pandemic (March 2020) as a function of predisposing, enabling and need factors. Analyses were carried out in the overall sample and restricted to those with moderate and severe symptoms (MSS) of depression and/or anxiety (n = 2,237). RESULTS: In individuals with MSS of depression and/or anxiety, 14.4% reported initiating new MHSU, 22.0% had no MHSU due to barriers and personal reasons and 36.7% had no MHSU due to self-reported no need. Age, living alone, lower income, a decrease in income during the pandemic and health professional status were associated with MHSU. Younger adults were more likely to initiate MHSU during the pandemic than older adults who reported not being comfortable to seek mental health care or self-reported no need. Individuals living alone and with lower income were more likely to report not being able to find an appointment for mental health care. CONCLUSIONS: Awareness campaigns focusing on older adults that explain the importance of seeking treatment is needed, as well as sensitising health professionals as to the importance of informing and aiding individuals at risk of social isolation and lower socio-economic status as to available mental health resources and facilitating access to care.

The effectiveness of transdiagnostic cognitive behavioural therapy for anxiety disorders: the role of and impact of comorbid depression.

Transdiagnostic Cognitive Behaviour Therapy (tCBT), an intervention designed to be applicable across multiple diagnoses, was introduced to improve limitations in traditional therapy such as cost and access to trained therapists. It has been established as an effective and efficacious treatment for anxiety disorders, though there has been little research focussed on the role of depression. The current study investigated the role of comorbid depression during tCBT for anxiety disorders in primary care settings as an outcome and a moderator of anxiety outcomes. Results of multi-level ANOVAs indicated no significant difference in anxiety outcomes regardless of whether there was a comorbid depression diagnosis in the tCBT condition, and that individuals with a comorbid depression diagnosis experienced significantly greater reduction in anxiety severity than those without. Depression symptom severity decreased to a significantly greater extent in the tCBT condition than in TAU when the outcome measure of Patient Health Questionnaire was utilised as the outcome measure, but this was not mirrored when the Clinician Severity Rating was utilised as the outcome measure. This study provides preliminary support for the effectiveness of Transdiagnostic Cognitive Behaviour therapy for those with both a principal anxiety disorder and comorbid depression in symptom reduction.

Cost-Effectiveness of Group Transdiagnostic Cognitive Behavioural Therapy for Anxiety Disorders in Primary Care Settings: Economic Evaluation From the Healthcare System Perspective Over a 1-Year Time Horizon.

AIM: To assess the incremental cost-effectiveness ratio (ICER) of group transdiagnostic cognitive-behavioural therapy (tCBT) added to treatment as usual (TAU) for anxiety disorders compared to TAU only from the healthcare system perspective over a 1-year time horizon. METHODS: Data from a pragmatic multisite randomized controlled trial where adults (18-65 years) with an anxiety disorder were randomized to tCBT + TAU (n = 117) or TAU (n = 114). Group tCBT is a 12-week (2h weekly sessions) community-based intervention. Health service utilization and related costs were captured from medico-administrative data and included those for the intervention, ambulatory visits, hospitalizations and medications. Effectiveness was based on quality-adjusted life years (QALYs). The study included measures at baseline, 4, 8, and 12 months. Intention-to-treat and complete case analyses were carried out. Missing data were imputed using multiple imputation analyses. Seemingly unrelated regression analyses were used to assess the effect of the intervention on total costs and QALYs while also adjusting for baseline confounders. The probability of cost-effectiveness of the intervention was assessed according to different willingness-to-pay (WTP) thresholds using the net benefit regression method. RESULTS: The ICER of tCBT + TAU as compared to TAU in the intention-to-treat analysis was $6,581/QALY. Complete case analyses showed a similar ICER of $6,642/QALY. The probability at a WTP threshold of $20,000 and $40,000 that tCBT + TAU as compared to TAU is cost-effective is 93.0% and 99.9%. CONCLUSION: tCBT added to TAU appears to be cost-effective from the healthcare system perspective for treating adult patients with anxiety disorders. Larger trials including young and older adults as well as a range of anxiety disorders are needed to further investigate the cost-effectiveness of tCBT in different patient populations.

Factors associated with change in moderate or severe symptoms of anxiety and depression in community-living adults and older adults during the COVID-19 pandemic.

OBJECTIVES: Few are the longitudinal studies on the changes in moderate or severe symptoms of anxiety or depression (MSS-ANXDEP) from before to during the COVID-19 pandemic in Canada. The aim was to study the change in MSS-ANXDEP and associated sociodemographic, economic, psychosocial, health behaviour and lifestyle, and clinical factors. METHODS: The current sample includes 59,997 adults aged ≥ 35 years participating in the 2018 and 2020 health surveys of the 5 established cohorts of the Canadian Partnership for Tomorrow's Health (CanPath). MSS-ANXDEP was based on a cutoff score ≥ 10 on the 7-item Generalized Anxiety Disorder Scale and Patient Health Questionnaire (PHQ-8). Change in MSS-ANXDEP was categorized as follows: no MSS-ANXDEP, remitted, incident, and persistent. Multinomial regressions were used to study MSS-ANXDEP as a function of sociodemographic, economic, psychosocial, health behaviours and lifestyle, and clinical factors. RESULTS: Sociodemographic and economic (i.e. age, gender, cohort, race/ethnicity, lower income, decreased in income, work status, being an essential worker), lifestyle and health behaviours (i.e. smoking, cannabis and alcohol use, drinking more alcohol), psychosocial (i.e. provide help to others, information and instrumental support, and change in relationships with friends, family, and partner) and clinical factors (i.e. lifetime mental disorder and multimorbidity) were associated with remitted, incident, and persistent MSS-ANXDEP. CONCLUSION: Health and socio-economic factors were associated with changes in symptoms of anxiety and depression during the pandemic, further increasing inequities in mental health needs. Public health campaigns on the importance of healthy behaviours should continue and health policies should reduce economic and social barriers to integrated substance use and mental health care.

RéSUMé: OBJECTIFS: Les études longitudinales sur l'évolution des symptômes modérés ou sévères d'anxiété ou de dépression (SMS-ANXDEP) avant et pendant la pandémie de COVID-19 au Canada sont rares. L'objectif était d'étudier l'association entre l'évolution des SMS-ANXDEP et les facteurs sociodémographiques, économiques, psychosociaux, cliniques et liés aux comportements et au mode de vie, avant et pendant la pandémie. MéTHODES: Ce grand échantillon comprend 59 997 adultes âgés de ≥ 35 ans qui ont participé aux enquêtes de santé 2018 et 2020 des 5 cohortes établies du Partenariat canadien pour la santé de demain (CanPath). La présence de SMS-ANXDEP a été définie par un résultat ≥ 10 sur les échelles Generalized Anxiety Disorder Scale à 7 items (GAD-7) et Patient Health Questionnaire (PHQ-8). Les changements dans les SMS-ANXDEP ont été catégorisés selon les patrons temporels suivants : absence, rémission, incidence et persistance de SMS-ANXDEP. Des régressions multinomiales multivariées ont été utilisées pour étudier les patrons temporels de SMS-ANXDEP en fonction, des facteurs socio-démographiques, économiques, associés au style de vie et aux comportements de santé, psychosociaux et cliniques. RéSULTATS: Les facteurs socio-démographiques et économiques (âge, genre, cohorte, race/ethnie, revenu inférieur, diminution du revenu, statut d'emploi, être un travailleur essentiel), associés au style de vie et aux comportements de santé (tabagisme, consommation de cannabis et d'alcool, consommation accrue d'alcool), psychosociaux (offrir de l'aide pendant la pandémie, soutien en information et instrumental, changement dans les relations avec les amis, la famille et la personne partenaire) et cliniques (trouble mental au cours de la vie, multimorbidité) étaient associés à la présence de SMS-ANXDEP en rémission, incident et persistant. CONCLUSION: Les patrons temporels des SMS-ANXDEP pendant la pandémie étaient associés aux facteurs socio-économiques et de santé, suggérant des inégalités accrues en matière de besoins de santé mentale. Les campagnes de santé publique sur l'importance d'adopter des comportements sains devraient continuer et les politiques de santé devraient réduire les barrières économiques et sociales aux soins intégrés de santé mentale et de toxicomanie.

Care trajectories of individuals with anxiety disorders: A retrospective cohort study.

BACKGROUND: Anxiety disorders (ADs) are associated with increased healthcare use (HCU), and individuals may seek healthcare through various pathways according to clinical and individual characteristics. This study aimed to characterize care trajectories (CTs) of individuals with ADs. METHODS: This is a retrospective cohort study using the Care Trajectories - Enriched Data cohort, a linkage between the Canadian Community Health Surveys (CCHS), and health administrative data from Quebec. The cohort included 5143 respondents reporting ADs to the CCHS between 2009 and 2016. We measured CTs over 5 years before CCHS using a state sequence analysis. RESULTS: The cohort was categorized into five types of CTs. Type 1 (52.7 %) was the lowest care-seeking group, with fewer comorbidities. Type 2 (24.0 %) had higher levels of physical and mental health comorbidities and moderate HCU, mainly ambulatory visits to general practitioners. Type 3 (13.1 %) represented older patients with the highest level of physical illnesses and high HCU, predominantly ambulatory consultation of specialists other than psychiatrists. Types 4 and 5 combined young and middle-aged patients suffering from severe psychological distress. HCU of type 4 (6.7 %) was high, mainly consultations of ambulatory psychiatrists, and HCU of type 5 (3.5 %), was the highest and mostly in acute care. LIMITATIONS: Administrative and survey data may have coding errors, missing data and self-report biases. CONCLUSION: Five types of CTs showed distinct patterns of HCU often modulated by physical and mental health comorbidities, which emphasizes the importance of considering ADs when individuals seek care for other mental health conditions or physical illness.

Moderators of the cost-effectiveness of transdiagnostic CBT for anxiety disorders over an 8-month time horizon using a net-benefit regression framework.

BACKGROUND: Access to evidence-based psychological treatment is a concern in many parts of the globe due to government-level financial constraints and patient-level barriers. Transdiagnostic cognitive behavioural therapy (tCBT) is an effective treatment approach that uses a single protocol for anxiety disorders which could enhance the dissemination of evidence-based psychotherapy. In a context of limited resources, the study of treatment moderators can allow to identify subgroups for which the cost-effectiveness of an intervention differs, information that could impact decision-making. So far, there has been no economic evaluation of tCBT for different subpopulations. The objectives of this study, using the net-benefit regression framework, were to explore clinical and sociodemographic factors as potential moderators of the cost-effectiveness of tCBT compared to treatment-as-usual (TAU). METHODS: This is a secondary data analysis of a pragmatic randomized controlled trial opposing tCBT added to TAU (n = 117) to TAU only (n = 114). Data on costs from the health system and the limited societal perspectives, as well as anxiety-free days, an effectiveness measure based on the Beck Anxiety Inventory, were collected over an 8-month time horizon and used to derive individual net-benefits. The net-benefit regression framework was used to assess moderators of the cost-effectiveness of tCBT + TAU as opposed to TAU alone. Variables of sociodemographic and clinical nature were assessed. RESULTS: Results showed that the number of comorbid anxiety disorders significantly moderated the cost-effectiveness of tCBT + TAU compared to TAU from the limited societal perspective. CONCLUSIONS: The number of comorbid anxiety disorders was identified as a moderator affecting the cost-effectiveness of tCBT + TAU compared to TAU from the limited societal perspective. More research is needed to strengthen the case of tCBT from an economic standpoint for large-scale dissemination. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02811458, 23/06/2016.

Mental health service use and associated predisposing, enabling and need factors in community living adults and older adults across Canada.

OBJECTIVES: Using Andersen's model of health care seeking behavior, we examined the predisposing, enabling, and need factors associated with mental health service use (MHSU) during the first wave of the COVID-19 pandemic across Canada. METHODS: The sample included n = 45,542 participants in the 5 established regional cohorts of the Canadian Partnership for Tomorrow's Health (CanPath) and who responded to the CanPath COVID-19 health survey (May-December 2020), with complete data on MHSU. Multivariable logistic regression analyses were carried out to study MHSU as a function of predisposing, enabling, and need factors. Analyses were stratified by regional cohort. RESULTS: Among the need factors, individuals reporting moderate/severe symptoms of depression and anxiety and poorer self-rated mental health were more likely to report MHSU. Among the enabling factors, receipt of informational/financial/practical support was associated with increased MHSU. While income was not consistently associated with MHSU, reported decrease in income was marginally associated with reduced MHSU. Among the predisposing factors, identifying as female or other gender minority was associated with increased MHSU, as was the presence of past-year cannabis use. In contrast, older age and alcohol consumption were associated with reduced MHSU. CONCLUSION: Need factors were consistently associated with MHSU. Although income inequities in MHSU were not observed, changes such as reduced income during the pandemic may lead to barriers in accessing mental health services. Future research should focus on better identifying contextual enabling factors and policies that overcome financial barriers to MHSU.

An examination of sudden gain prevalence across cognitive-behavioural therapy for anxiety and depressive disorders: A quantitative analysis and meta-analytic review.

Sudden gains, incidences of unexpectedly large and stable session to session symptom reductions during psychotherapy, have been shown in samples of individuals receiving treatment for both anxiety and depressive disorders, although seemingly more frequently in sample receiving treatment for depressive disorders. This may suggest that sudden gains are a function of depression, but the high comorbidity between anxiety and depressive disorders makes this difficult to assess. Study One utilised a sample of 117 adults undergoing CBT for a principal anxiety disorder to explore the effect of comorbid depression on sudden gain prevalence. Results indicated that sudden gains were not more prevalent in the comorbid depression group; however, the frequency of sudden gains was significantly related to comorbid depressive disorder severity. Study Two involved a meta-analysis of 48 studies to compare sudden gain prevalence between trials of CBT for depressive disorders versus anxiety-related disorders. The results of the meta-analysis indicated significantly higher rates of sudden gains in samples with a principal depressive disorder diagnosis, compared to a principal anxiety disorder diagnosis. Sudden gains may therefore be driven by depression, but only at the more severe level.

Experience of LGBTQIA2S+ populations with gambling during the COVID-19 pandemic: protocol for a mixed-methods study.

INTRODUCTION: Research undertaken since the beginning of the COVID-19 pandemic has provided us information about the impact of the pandemic on the gambling habits of the general population. However, very little is known about certain subgroups at increased risk of developing gambling disorder, such as the LGBTQIA2S+ population. The purpose of this study is to describe the impact of the COVID-19 pandemic on gambling behaviours among LGBTQIA2S+ individuals. In addition, we want to understand the experiences of the LGBTQIA2S+ population with gambling disorder and identify interventions that LGBTQIA2S+ people have found to be effective in addressing problem gambling during the COVID-19 pandemic. METHODS AND ANALYSIS: This study has a sequential explanatory mixed-method design in two phases over 2 years. The first phase is a correlational study. We will conduct a cross-sectional survey using a stratified random sampling among Canadian residents who are 18 years of age or older, self-identify as sexually and gender-diverse (ie, LGBTQIA2S+) and have gambled at least once in the previous 12 months. This survey will be administered online via a web panel (n=1500). The second phase is a qualitative study. Semistructured interviews will be conducted with LGBTQIA2S+ people with problematic gambling (n=30). ETHICS AND DISSEMINATION: This research project has been ethically and scientifically approved by the Research Ethics Committee and by the CIUSSS de l'Estrie-CHUS scientific evaluation committee on 3 March 2022 (reference number: 2022-4633-LGBTQ-JHA). Electronic and/or written informed consent, depending on the data collection format (online survey and online or in-person interviews), will be obtained from each participant. A copy of the consent form and contact information will be delivered to each participant.

An analysis of differential improvement by diagnosis in group transdiagnostic cognitive behaviour therapy for anxiety disorders.

INTRODUCTION: Anxiety disorders are the most prevalent among the mental health disorders and have a negative impact on an individual's life. Cognitive behaviour therapy (CBT) is documented as the most effective treatment for anxiety disorders. However, challenges associated with implementing diagnosis-specific CBT have led to transdiagnostic approaches of CBT (tCBT). tCBT uses a single protocol with core elements of CBT for treatment of anxiety disorders broadly. The aim of the current study is to examine whether participants with different principal anxiety diagnoses demonstrate similar anxiety reduction. METHODS: The current study involved a secondary analysis of 117 participants randomly allocated to receive tCBT for anxiety disorders in a pragmatic randomised effectiveness trial. Beck Anxiety Inventory (BAI) and Clinician Severity Ratings (CSR) scales were administered at pre- and post-treatment and one-year follow-up, while the Anxiety Disorder Diagnostic Questionnaire - Weekly (ADDQ-W) was administered each session. RESULTS: Mixed-factorial analyses of variance (ANOVAs) indicated that participants with GAD, SAD and PD/A improved to post-treatment and maintained to follow-up, with no differential improvement across principal diagnoses. Mixed effect regression modelling of session by session measures indicated non-differential negative slopes across principal diagnoses of GAD, SAD and PD/A. CONCLUSION: Overall, results indicate that group tCBT for anxiety disorders shows equal effectiveness for GAD, PD/A, and SAD in real-world conditions.

Cost-effectiveness of transdiagnostic group cognitive behavioural therapy for anxiety disorders v. treatment as usual: economic evaluation of a pragmatic randomized controlled trial over an 8-month time horizon using self-reported data.

BACKGROUND: This economic evaluation supplements a pragmatic randomized controlled trial conducted in community care settings, which showed superior improvement in the symptoms of adults with anxiety disorders who received 12 sessions of transdiagnostic cognitive-behavioural group therapy in addition to treatment as usual (tCBT + TAU) compared to TAU alone. METHODS: This study evaluates the cost-utility and cost-effectiveness of tCBT + TAU over an 8-month time horizon. For the reference case, quality-adjusted life years (QALYs) obtained using the EQ-5D-5L, and the health system perspective were chosen. Alternatively, anxiety-free days (AFDs), derived from the Beck Anxiety Inventory, and the limited societal perspective were considered. Unadjusted incremental cost-effectiveness/utility ratios were calculated. Net-benefit regressions were done for a willingness-to-pay (WTP) thresholds range to build cost-effectiveness acceptability curves (CEAC). Sensitivity analyses were included. RESULTS: Compared to TAU (n = 114), tCBT + TAU (n = 117) generated additional QALYs, AFDs, and higher mental health care costs from the health system perspective. From the health system and the limited societal perspectives, at a WTP of Can$ 50 000/QALY, the CEACs showed that the probability of tCBT + TAU v. TAU being cost-effective was 97 and 89%. Promising cost-effectiveness results using AFDs are also presented. The participation of therapists from the public health sector could increase cost-effectiveness. CONCLUSIONS: From the limited societal and health system perspectives, this first economic evaluation of tCBT shows favourable cost-effectiveness results at a WTP threshold of Can$ 50 000/QALY. Future research is needed to replicate findings in longer follow-up studies and different health system contexts to better inform decision-makers for a full-scale implementation.

Demand management processes to improve access to cognitive-behavioral therapies for anxiety disorders: a grounded theory study.

Introduction: Anxiety disorders are impactful mental health conditions for which evidence-based treatments are available, notably cognitive-behavioral therapies (CBTs). Even when CBTs are available, demand-side factors limit their access, and actors in a position to perform demand management activities lack a framework to identify context-appropriate actions. Methods: We conducted a constructivist grounded theory study in Quebec, Canada, to model demand management targets to improve access to CBTs for anxiety disorders. We recruited key informants with diverse experiences using purposeful, then theoretical sampling. We analyzed data from 18 semi-directed interviews and 20 documents through an iterative coding process centered around constant comparison. Results: The resulting model illustrates how actors can target clinical-administrative processes fulfilling the demand management functions of detection, evaluation, preparation, and referral to help patients progress on the path of access to CBTs. Discussion: Modeling clinical-administrative processes is a promising approach to facilitate leveraging the competency of actors involved in demand management at the local level to benefit public mental health.

[Short-term interventions offered by les centres locaux de services communautaires (CLSC) to people living with anxiety or depressive disorders: Results of the longitudinal component of the Shared Knowledge study]. / Les interventions de courte durée offertes par les centres locaux de services communautaires (CLSC) aux personnes traversant un épisode de troubles anxieux ou dépressifs : une étude longitudinale au Québec.

Context In Quebec, adult mental health (AMH) first-line teams are mandated to provide psychosocial services to people living with mental health difficulties, including anxiety and mood disorders. Following the establishment of new clinical guidelines in 2017, the duration of interventions was not to exceed 15 sessions, with some exceptions. Objectives The overall aim of the longitudinal component of the Shared Knowledge study was to evaluate the care experience of individuals with an anxiety or depressive disorder receiving a short-term intervention (<15 sessions) by first-line AMH teams, and the evolution of recovery over time. Specifically, the objectives were to: 1) determine the appreciation of short-term interventions by service users; and 2) assess the evolution over time of the symptomatology, functioning and quality of life and recovery of individuals receiving short-term interventions. Method A mixed method longitudinal design was used. Telephone interviews were conducted with participants, in which the following variables were quantitatively and qualitatively assessed: appreciation of services received, quality of relationship with the provider (INSPIRE), depressive symptoms (PHQ-9), anxiety symptoms (GAD-7), global functioning (WHODAS), quality of life (ReQOL), and personal recovery (ERTAD). Linear mixed model analyses were performed to examine changes over time on quantitative measures. Content analysis was performed on the qualitative data. Results A total of 63 individuals participated in an interview before the start of their intervention and 22 of them participated after the end of this intervention. Statistical analyses showed a significant improvement in anxiety symptoms, quality of life, and personal recovery, but no difference was observed in depressive symptoms and level of functioning. Nearly half (47.4%) of participants reported that the intervention they received had "completely" met the need that had led them to seek help, and 33.3% felt "completely" equipped or empowered in their recovery. The quality of the relationship with the caregiver, the opportunity to take part in decision-making, and the personalization of the intervention according to their needs and preferences were some of the elements that were particularly appreciated. Conclusion Short-term interventions seem to be appreciated and produce positive effects in many people suffering from anxiety or depressive disorders. However, they remain insufficient for a number of them. A personal recovery measure should be used in conjunction with symptomatology and functioning scales to monitor the progress of people using first-line mental health services.

[A Portrait of Generalized Anxiety Symptoms in a Sample of High School Students: The Importance of Prevention, Screening and Intervention]. / Portrait des symptômes d'anxiété généralisée chez les élèves du secondaire : l'importance de la prévention, du dépistage et de l'intervention.

Anxiety disorders are among the most prevalent psychopathologies in children and adolescents around the world. They affect their personal, family, school and social functioning. Although symptoms of generalized anxiety disorder (GAD) are among the most commonly observed symptoms in adolescence, relatively little is known about the most important risk factors. Objectives The purpose of the present study was therefore 1) to document the prevalence of the central feature of GAD, excessive worrying, in high school students aged 12 to 17 years, by identifying the percentage of students reporting low, medium, and high levels of symptoms, 2) to identify key sociodemographic characteristics associated with high symptom level, and 3) to identify individual and family risk factors associated with high symptom level and estimate their relative contribution. Method A total of 8689 Quebec high school students (55.9% girls) participated in the study. The average age of these students was 14.34 years (SD=1.52). A k-means cluster analysis was first performed to create three categories based on the symptoms of generalized anxiety presented by the participants (low, medium, high). Multinomial logistic regression analyzes were then performed to identify the variables that best predict membership in these different categories. Results The results showed that 35.1% of the students reported a low level of symptoms, 40.2% reported an average level of symptoms, while 24.7% reported a high level of symptoms. Girls and adolescents in higher grades were more likely to report high levels of symptoms. Several factors were also identified as increasing the risk of being in the high generalized anxiety symptoms category compared to the average generalized anxiety symptoms and low generalized anxiety symptoms categories. These include fear of negative evaluation by others, perfectionism, depressed feelings, negative problem orientation and cognitive avoidance. Conclusion This study supports previous research showing that girls are at greater risk of developing generalized anxiety disorder. It also highlights the multidimensional aspect of the problem, by identifying the most important risk factors. Ultimately, this better understanding of the factors involved will allow us to better identify the targets to prioritize in the prevention of generalized anxiety disorders in adolescence.

Mindfulness-based stress reduction to improve depression, pain and high patient global assessment in controlled rheumatoid arthritis.

Objective: The aim was to improve distressing patient-reported outcomes (PROs) that persisted in RA patients with clinically controlled inflammation (controlled RA). Methods: In a pragmatic pilot study, we offered mindfulness-based stress reduction (MBSR), a group intervention, to controlled RA patients who had high (≥16) Centre for Evaluation Studies depression (CES-D) scores and/or patient general assessment of disease activity (PGA) at least 2/10 larger than evaluator general assessment (EGA) (PGA-EGA: Delta). Evaluations before, 6 and 12 months after MBSR included CES-D, PGA, modified HAQ, simple disease activity index (SDAI), anxiety (general anxiety disorder 7; GAD-7), coping strategies (coping with health injuries and problems; CHIP), sleep disturbance and pain. Facilitators and obstacles to recruitment and participation were identified. A subset of patients was interviewed for qualitative analysis of their experience. Results: Out of 306 screened patients, 65 were referred, 39 (60%) agreed and 28 (43%) completed MBSR. Anticipated burden, timing and frequency of group meetings, commuting issues, age extremes and co-morbidities were barriers to participation. Up to 12 months after MBSR, anxiety, depression, emotion-oriented coping, sleep and function significantly improved. Nonetheless, no significant impact was observed on pain, PGA, Delta or SDAI. The interviews revealed that benefits, including integration of effective coping strategies, were maintained. Conclusion: We addressed MBSR feasibility issues and selection of outcomes in controlled RA patients with distressing PROs. For patients who chose to participate in MBSR, lasting benefits were evident for anxiety, depression, sleep and function. Larger studies are required to evaluate the weaker impact of MBSR on RA-related pain and PGA.

French adaptation and validation of the Panic Disorder Severity Scale-self-report.

BACKGROUND: The aims of this study were to conduct a cross-cultural validation of the Panic Disorder Severity Scale - Self-Report (PDSS-SR) and to examine psychometric properties of the French-Canadian version. METHODS: A sample of 256 adults were included in the validation study based on data from the baseline interview of a clinical trial on transdiagnostic cognitive-behavioral therapy for mixed anxiety disorders. Participants completed the Anxiety and Related Disorders Interview Schedule (ADIS-5), and self-report instruments including the PDSS-SR, Beck Anxiety Inventory (BAI), Mobility Inventory for Agoraphobia (MIA), Sheehan Disability Scale (SDS), Patient Health Questionnaire (PHQ-9), Social Phobia Inventory (SPIN), Insomnia Severity Index (ISI) and Penn State Worry Questionnaire (PSWQ). The cross-cultural adaptation in French of the PDSS-SR included a rigorous back-translation process, with an expert committee review. Sensitivity to change was also examined with a subgroup of patients (n = 72) enrolled in the trial. RESULTS: The French version of the PDSS-SR demonstrated good psychometric properties. The exploratory factor analysis supported a one factor structure with an eigenvalue > 1 that explained 64.9% of the total variability. The confirmatory factor analysis (CFA) corroborated a one-factor model with a good model fit. Internal consistency analysis showed a .91 Cronbach's alpha. The convergent validity was adequate with the ADIS-5 clinical severity ratings for panic disorder (r = .56) and agoraphobia (r = .39), as well as for self-report instruments [BAI (r = .63), MIA (accompanied: r = .50; alone: r = .47) and SDS (r = .37)]. With respect to discriminant validity, lower correlations were found with the SPIN (r = .17), PSWQ (r = .11), ISI (r = .19) and PHQ-9 (r = .28). The optimal threshold for probable diagnosis was 9 for the PDSS-SR and 4 for the very brief 2-item version. The French version showed good sensitivity to change. CONCLUSIONS: The French version of the PDSS-SR has psychometric properties consistent with the original version and constitutes a valid brief scale to assess the severity of panic disorder and change in severity over time, both in research and clinical practice.
