BACKGROUND: Genitopelvic pain following childbirth is common and likely to challenge the psychological, relational, and sexual well-being of new mothers. While genitopelvic pain generally decreases during the postpartum period, personal and interpersonal characteristics may explain why genitopelvic pain persists beyond the period of physical recovery in some mothers. Body image concerns, increased stress, and relationship challenges would be particularly salient during pregnancy and the postpartum period, which could put new mothers at greater risk of sexual difficulties. Also, mothers may display a negative appraisal regarding genitopelvic pain and doubt their ability to cope with it, which may contribute to the pain. AIM: The current study aimed to examine the role of perfectionism, body image concerns, and perceived intimacy in the occurrence and change in genitopelvic pain in new mothers in postpartum. METHODS: A total of 211 new mothers and their partners were recruited for a larger prospective dyadic study on the transition to parenthood. OUTCOMES: Mothers completed a single item assessing genitopelvic pain, in addition to brief validated questionnaires measuring perfectionism, body image concerns, and perceived couple intimacy during pregnancy and at 4, 8, and 12 months postpartum. RESULTS: Five multilevel modeling analyses revealed that adaptive perfectionism, maladaptive perfectionism, and body image concerns were associated with a higher occurrence of genitopelvic pain from 4 to 12 months postpartum. Mothers' and partners' perceived intimacy was not significantly related to new mothers' genitopelvic pain. None of the predictors modified the trajectory of genitopelvic pain over time. CLINICAL IMPLICATIONS: Raising awareness among health care professionals regarding the role of perfectionism and body image concerns in genitopelvic pain may help them identify new mothers at risk of chronic genitopelvic pain, while offering a new avenue of intervention. STRENGTHS AND LIMITATIONS: There has been little research examining the role of perfectionism, body image concerns, and intimacy in postpartum genitopelvic pain. Based on a longitudinal prospective approach, this study identified perfectionism and body image concerns as significant predictors of postpartum genitopelvic pain. However, prepregnancy genitopelvic pain, genitopelvic pain intensity, and sexual distress were not measured. CONCLUSION: Adaptive and maladaptive perfectionism and body image concerns are associated with new mothers' genitopelvic pain up to 12 months postpartum.

BACKGROUND: The aim of this study was to examine the temporal and dyadic associations between anxiety and depressive symptoms during the transition to parenthood (TTP), while exploring the antecedence of attachment insecurities in these associations. METHOD: Couples of first-time parents (N = 211) completed the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, the Experiences in Close Relationships scale, and a sociodemographic questionnaire during the second trimester of pregnancy and at four and twelve months postpartum. RESULTS: Both prenatal anxiety and depressive symptoms predicted postnatal depressive and anxiety symptoms. Prenatal attachment-related anxiety predicted higher postnatal anxiety and depressive symptoms whereas prenatal attachment-related avoidance predicted higher postnatal depressive symptoms only. Parents whose partners had a higher level of prenatal attachment-related anxiety experienced higher postnatal anxious and depressive symptoms via their own's prenatal depressive symptoms. Parents whose partners had a higher level of prenatal attachment-related avoidance experienced higher postnatal depressive symptoms via their own's prenatal anxious symptoms. No gender differences were found for these associations. LIMITATIONS: The sample was predominantly composed of educated heterosexual French-Canadian Caucasian couples and all measures were self-reported. CONCLUSIONS: Our original findings suggest that professionals should routinely screen for anxiety and depressive symptoms in both partners from pregnancy up to one year postpartum. Also, our findings suggest addressing attachment insecurities with both partners to prevent the development of future symptoms during pregnancy or after childbirth. Finally, our study supports the relevance of considering these symptoms at subclinical levels during the TTP.

PURPOSE: To explore the intensity and variation of workers' worries, pain, psychosocial factors, and margin of manoeuvre before and after a return-to-work program, and identified the psychosocial factors associated with non-return to work at the end of the rehabilitation program. METHODS: A pre-post study design was used. A convenience sample of 80 workers starting a return-to-work program and having a compensated musculoskeletal injury that caused an absence of more than three months from their regular work was recruited. Data were collected at baseline and at the end of the rehabilitation program on the nature of the worries and maintenance factors defined in Dugas' generalized anxiety and worry model, using validated questionnaires. The margin of manoeuvre was assessed by the treating occupational therapist. A series of descriptive analyses were performed, as well as Generalized Estimating Equations analyses. RESULTS: Workers' worries were work-related or disability-related 83% of the time at baseline. These worries were essentially based on the situation then occurring at work 90% of the time. For the Generalized Estimating Equations analyses on work status, the final model was significant, explaining 54% of the variance in non-return to work (Pseudo R2 = 0.54; p = 0.0001). Workers were 8.52 times less likely to return to work when the margin of manoeuvre was insufficient, and twice as likely not to return to work in the presence of intense worry. Worries were significantly associated with insufficient margin of manoeuvre. CONCLUSION: A strong association between workers' lack of margin of manoeuvre at work and their worries about their return to work, and poor work outcomes, supports the importance of the worker-environment interaction in rehabilitation programs.

In this study, we combined the results of two controlled trials and examined the relationships between working alliance, telepresence, cognitive change and treatment outcome. Sixty-five participants with a primary diagnosis of generalized anxiety disorder (GAD) or panic disorder with agoraphobia (PDA) received cognitive behaviour therapy delivered via videoconference. Participants completed measures of working alliance and telepresence after three psychotherapy sessions. They also completed measures of treatment outcome and dysfunctional beliefs (cognitive change) specific to PDA and GAD at pretreatment and posttreatment. Results revealed that telepresence at the fifth session moderated the relationship between the working alliance at the first and fifth sessions. As telepresence increased, its impact on the working alliance diminished. Cognitive change mediated the relationship between the working alliance at the fifth session and treatment outcome.

Context Anxiety disorders are among the most prevalent psychopathologies for children and adolescents in Quebec. The prevalence of anxiety disorders is very high and has been affecting a growing number of young people for the past 10 years. It is possible to observe an increased number of anxiety prevention programs for young people around the world. However, some authors point out that they are rarely faithfully implemented, sustained, and scaled up in several schools. Based on implementation science, this HORS-PISTE program was developed to address these important issues by preventing anxiety in Quebec high school students. Implemented in more than 100 schools, the program is now part of Action 4.3 (Promote the deployment of the HORS-PISTE program) of the new interdepartmental Action Plan on Mental Health of the Government of Quebec (2022). Purpose This article aims to describe how the Knowledge-to-Action (KTA) framework, derived of implementation science, was used to design, implement, sustain, evaluate, and scale up the HORS-PISTE program. This framework proposes a cyclical process in seven phases. Method A multi-method and multi-stakeholder approach was conducted with a grant from the Public Health Agency of Canada's Mental Health Promotion Innovation Fund, which has been supporting 20 innovative projects across Canada since 2019. It includes a pre-post evaluation protocol consisting of validated questionnaires, surveys (administered to students, parents, and teachers), semi-structured logbooks completed by program facilitators and implementation review meetings in each school. The different cycles of the program development, implementation and evaluation are discussed through the KTA framework phases. Results From 2017 to 2021, this methodology made it possible to evaluate and readjust the program each year to promote its adaptation and prepare its scaling up. This article highlights the data collected and analyzed in relation to the seven phases of the KTA framework. Conclusion This article demonstrates how implementation science can support designers of anxiety prevention programs who are concerned by scaling up and sustaining their programs. Issues in combining the scientific rigor of evaluation with the reality of the field are also raised.

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.

Delivering psychotherapy by videoconference has been studied in a number of clinical trials, but no large controlled trial has involved generalized anxiety disorder (GAD). This multicenter randomized controlled non-inferiority trial was conducted to test if cognitive-behavior psychotherapy delivered by videoconference (VCP) is as effective as cognitive-behavior psychotherapy delivered face-to-face, using a strict margin of tolerance for non-inferiority. A total of 148 adults received a 15-session weekly manualized program. The treatment was based on the intolerance of uncertainty model of GAD. The impact of treatment was assessed using primary (GAD severity), secondary (worry, anxiety, and intolerance of uncertainty) and tertiary (general functioning) variables measured before and after treatment and at 6-month and 12-month follow-ups. Results showed that: (a) the treatment was effective; (b) VCP for GAD was statistically non-inferior to face-to-face psychotherapy on primary, secondary and tertiary measures at all assessment points; (c) change in intolerance of uncertainty significantly predicted change in the primary outcome measure over and above important clinical factors common to all psychotherapies (motivation, working alliance, perceived therapist competence, and client satisfaction). These findings support the use of VCP as a promising treatment option for adults with GAD. Clinical trial registry: ISRCTN#12662027.

A growing body of research examines the COVID-19 pandemic's effects on well-being. Only few studies focus on older adults or explore the predictors of COVID-19-related anxiety. Intolerance of uncertainty (IU) and some behaviors (e.g., avoidance, procrastination) are linked to anxiety among older adults and could both be relevant to consider in a pandemic context. This study measured the occurrence and anxiety levels among older adults and verified the possible role of IU and behaviors in predicting anxiety symptoms, impairment and distress related to COVID-19 health standards. It also examined the indirect effect of IU on symptoms, impairment and distress through behaviors. Participants aged 60 and over (N = 356) were recruited and administered questionnaires. Anxiety levels and symptom impairment were high and appeared to have increased since the beginning of the pandemic. IU and behavioral manifestations of anxiety were associated with higher anxiety symptoms, impairment and distress related to COVID-19 health standards. The indirect effects of IU on the tendency to worry and COVID-19-related anxiety through behavioral manifestations of anxiety were confirmed. This study provides knowledge on the relationship between COVID-19 and anxiety in older adults and identifies predictors relevant to this population.

Background: Several studies conducted since the beginning of the COVID-19 pandemic have shown its harmful effects on young people's mental health. In Québec and Canada, few studies have focussed on adolescents, and even fewer of these studies have examined this subject using a methodology that involved comparisons of data obtained before and during the pandemic, which is the purpose of this study. Objective: The objective of this study is to determine the impact of the COVID-19 pandemic on the anxiety of secondary 1 and 2 students in Québec, using data obtained before and during the pandemic. Method: Participants were 2990 French Canadian students in secondary 1 (grade 7) and secondary 2 (grade 8) in Québec. Two independent samples completed the questionnaires, one sample before the pandemic (fall 2019) and one sample during the pandemic (fall 2020). Their answers were subjected to descriptive analysis and multivariate analysis of variance. Results: Results show that the pandemic has had variable impacts on the student's mental health, with some of them reporting negative effects on their lives, others reporting no effect, and some reporting positive effect. However, the students surveyed during the pandemic generally reported more symptoms of generalized anxiety, and higher levels of test anxiety, fear of judgment and perfectionism than the ones surveyed before the pandemic. Conclusions: The discussion puts forward possible explanations for the results obtained, which contribute to a better understanding of young adolescents' experience during the COVID-19 pandemic. It also discusses the importance of developing interventions for adolescents affected by this pandemic.

BACKGROUND: Only a small proportion of older patients with generalized anxiety disorder (GAD) seek professional help. Difficulties in accessing treatment may contribute to this problem. Guided self-help based on the principles of cognitive-behavioral therapy (GSH-CBT) is one way of promoting access to psychological treatment. Moreover, because the therapist's role in GSH-CBT is limited to supporting the patient, this role could be assumed by trained and supervised lay providers (LPs) instead of licensed providers. The main goal of this study is to evaluate the efficacy of GSH-CBT guided by LPs for primary threshold or subthreshold GAD in older adults. METHODS: We will conduct a multisite randomized controlled trial comparing an experimental group receiving GSH-CBT guided by LPs (n = 45) to a wait-list control group (n = 45). Treatment will last 15 weeks and will be based on a participant's manual. Weekly telephone sessions with LPs (30 min maximum) will be limited to providing support. Data will be obtained through clinician evaluations and self-assessment questionnaires. Primary outcomes will be the tendency to worry and severity of GAD symptoms. Secondary outcomes will be anxiety symptoms, sleep difficulties, functional deficit, diagnosis of GAD, and cognitive difficulties. For the experimental group, measurements will take place at pre- and post-treatment and at 6 and 12 months post-treatment. For the control group, three evaluations are planned: two pre-treatment evaluations (before and after the waiting period) and after receiving treatment (post-treatment). The efficacy of GSH-CBT will be established by comparing the change in the two groups on the primary outcomes. DISCUSSION: This project will provide evidence on the efficacy of a novel approach to treat GAD in older adults. If effective, it could be implemented on a larger scale and provide many older adults with much needed mental health treatment through an expanded workforce. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov, number NCT03768544 , on December 7, 2018.

BACKGROUND: Previous meta-analyses have shown a significant relationship between working alliance and treatment outcome in general. Some studies have examined the relationship between working alliance and treatment outcome during telepsychotherapy, but to the best of our knowledge, no study has examined the mediating role of individual components of the working alliance. OBJECTIVE: As part of a clinical trial of cognitive behavioral therapy (CBT) for generalized anxiety disorder (GAD) delivered by videoconference (VC), the aim of this study is to examine the mediating role of intolerance of uncertainty on the relationship between the components of the working alliance and treatment outcome. METHODS: A sample of 46 adults with primary GAD received 15 sessions of CBT for GAD delivered over VC. Participants completed the measure of working alliance immediately after the fifth therapy session. The degree of change in intolerance of uncertainty (a key psychological process) was assessed from pre- to posttreatment. Treatment outcome was assessed via changes in GAD symptoms from pretreatment to the 6-month follow-up. RESULTS: The results revealed that the therapeutic bond did not predict treatment outcome (r=-0.23; P=.12). However, agreement on therapeutic goals and tasks did predict treatment outcome (r=-0.42; P=.004 and r=-0.37; P=.01, respectively). In addition, the relationship between consensus on therapeutic tasks and treatment outcome was completely mediated by changes in intolerance of uncertainty (unstandardized ß=-0.03; r2=0.12), whereas consensus relative to treatment goals had a direct impact on treatment outcome. CONCLUSIONS: These results provide a better understanding of the differential role of the components of the working alliance in telepsychotherapy as a facilitative factor for changes in key cognitive processes, leading to therapeutic change.

This study aims to examine two explanatory factors of relationship satisfaction and parental alliance among both parents of a new child, namely romantic attachment and perfectionism. A sample of 80 couples completed individual online questionnaires. Path analyses based on the Actor-Partner Interdependence Model were carried out to explore the actor and partner effects of each explanatory variable (attachment, perfectionism) on both partners' postnatal relationship satisfaction and parental alliance. Results revealed that attachment avoidance is negatively related to each partner's own relationship satisfaction and parental alliance, whereas attachment anxiety is related to their own lower parental alliance. Maladaptive perfectionism is negatively related to each partner's own relationship satisfaction, whereas adaptive perfectionism is positively related to each partner's own relationship satisfaction. These results extend the understanding of the factors contributing to parental and couple adaptation in the postnatal period. They highlight the role of attachment and perfectionism for improving postnatal professionals' interventions.

The Geriatric Anxiety Inventory (GAI) and its short form (GAI-SF) are self-reported scales used internationally to assess anxiety symptoms in older adults. In this study, we conducted the first critical comprehensive review of these scales' psychometric properties. We rated the quality of 31 relevant studies with the COSMIN checklist. Both the GAI and GAI-SF showed adequate internal consistency and test-retest reliability. Convergent validity indices were highest with generalized anxiety measures; lowest with instruments relating to somatic symptoms. We detected substantial overlap with depression measures. While there was no consensus on the GAI's factorial structure, we found the short version to be unidimensional. Although we found good sensitivity and specificity for detecting anxiety, cut-off scores varied. The GAI and GAI-SF are relevant instruments showing satisfactory psychometric properties; to broaden their use, however, some psychometric properties warrant closer examination. This review calls attention to weaknesses in the methodological quality of the studies.

BACKGROUND: Transdiagnostic group cognitive-behavioral therapy (tCBT) is a delivery model that could help overcome barriers to large-scale implementation of evidence-based psychotherapy for anxiety disorders. The aim of this study was to assess the effectiveness of combining group tCBT with treatment-as-usual (TAU), compared to TAU, for the treatment of anxiety disorders in community-based mental health care. METHODS: In a multicenter single-blind, two-arm pragmatic superiority randomized trial, we recruited participants aged 18-65 who met DSM-5 criteria for principal diagnoses of generalized anxiety disorder, social anxiety disorder, panic disorder, or agoraphobia. Group tCBT consisted of 12 weekly 2 h sessions. There were no restrictions for TAU. The primary outcome measures were the Beck Anxiety Inventory (BAI) and clinician severity rating from the Anxiety and Related Disorders Interview Schedule for DSM-5 (ADIS-5) for the principal anxiety disorder at post-treatment, with intention-to-treat analysis. RESULTS: A total of 231 participants were randomized to either tCBT + TAU (117) or TAU (114), with outcome data available for, respectively, 95 and 106. Results of the mixed-effects regression models showed superior improvement at post-treatment for participants in tCBT + TAU, compared to TAU, for BAI [p < 0.001; unadjusted post-treatment mean (s.d.): 13.20 (9.13) v. 20.85 (10.96), Cohen's d = 0.76] and ADIS-5 [p < 0.001; 3.27 (2.19) v. 4.93 (2.00), Cohen's d = 0.79]. CONCLUSIONS: Our findings suggest that the addition of group tCBT into usual care can reduce symptom severity in patients with anxiety disorders, and support tCBT dissemination in routine community-based care.

OBJECTIVES: Assessing late-life anxiety using an instrument with sound psychometric properties including cross-cultural invariance is essential for cross-national aging research and clinical assessment. To date, no cross-national research studies have examined the psychometric properties of the frequently used Geriatric Anxiety Inventory (GAI) in depth. METHOD: Using data from 3,731 older adults from 10 national samples (Australia, Brazil, Canada, The Netherlands, Norway, Portugal, Spain, Singapore, Thailand, and United States), this study used bifactor modeling to analyze the dimensionality of the GAI. We evaluated the "fitness" of individual items based on the explained common variance for each item across all nations. In addition, a multigroup confirmatory factor analysis was applied, testing for measurement invariance across the samples. RESULTS: Across samples, the presence of a strong G factor provides support that a general factor is of primary importance, rather than subfactors. That is, the data support a primarily unidimensional representation of the GAI, still acknowledging the presence of multidimensional factors. A GAI score in one of the countries would be directly comparable to a GAI score in any of the other countries tested, perhaps with the exception of Singapore. DISCUSSION: Although several items demonstrated relatively weak common variance with the general factor, the unidimensional structure remained strong even with these items retained. Thus, it is recommended that the GAI be administered using all items.

Our work aimed at evaluating the use of permeability glycoprotein (P-gp) inhibiting nanoparticles (NPs) as a part of a suitable oral solid dosage to improve bioavailability. Famotidine (Pepcid®), a stomach acid production inhibitor, was used as a drug model to test our hypothesis. Famotidine-loaded NPs were prepared by solvent emulsion evaporation using PEG grafted on a polylactide acid (PLA) polymer backbone (PLA-g-PEG), with a 5% molar ratio of PEG versus lactic acid monomer and PEG of either 750 or 2000 Da molecular weight. Tablet formulation was composed of 40% Famotidine-loaded NPs, 52.5% microcrystalline cellulose as filler, 7% pre-gelatinized starch as binder/disintegrant, and 0.5% magnesium stearate as lubricant. Tablets containing 1.6 mg of Famotidine were prepared at an average weight of 500 mg, thickness of 6.2-6.5 mm, hardness of 5-8 kp, and disintegration time of <1 min. Our results suggest that Famotidine-loaded NPs using grafted PEG-g-PLA polymers can be formulated as an oral solid dosage form while effectively inhibiting P-gp mediated Famotidine efflux, irrespective of PEG molecular weights. This could therefore represent an attractive formulation alternative to enhance oral permeability and bioavailability of drugs that are P-gp substrates.

OBJECTIVES: To estimate the 6-month prevalence of generalized anxiety disorder (GAD) in primary care patients aged 70 years and above and to describe their clinical profile, including types of worries. METHODS/DESIGN: Participants (N = 1193) came from the Étude sur la Santé des Aînés (ESA) services study conducted in Quebec, Canada. An in-person structured interview was used to identify GAD and other anxiety/depressive disorders as well as to identify types of worries. Three groups were created (ie, patients with GAD, patients with another anxiety disorder, and patients without anxiety disorders) and compared on several sociodemographic and clinical characteristics using multinomial logistic regression analyses. RESULTS: The 6-month prevalence of GAD was 2.7%. Findings also indicated that the most common types of worries were about health, being a burden for loved ones, and losing autonomy. Compared with respondents without anxiety disorders, older patients with GAD were more likely to be women, be more educated, suffer from depression, use antidepressants, be unsatisfied with their lives, and use health services. In comparison with respondents with another anxiety disorder, those with GAD were 4.5 times more likely to suffer from minor depression. CONCLUSIONS: GAD has a high prevalence in primary care patients aged 70 years and above. Clinicians working in primary care settings should screen for GAD, since it remains underdiagnosed. In addition, it may be associated with depression and life dissatisfaction. Screening tools for late-life GAD should include worry themes that are specific to aging.

BACKGROUND: Anxiety disorders are the most common mental disorders in community settings, and they are associated with significant psychological distress, functional and social impairment. While cognitive behaviour therapy (CBT) is the most consistently efficacious psychological treatment for anxiety disorders, barriers preclude widespread implementation of CBT in primary care. Transdiagnostic group CBT (tCBT) focuses on cognitive and behavioural processes and intervention strategies common to different anxiety disorders, and could be a promising alternative to conventional CBT. This study aims to examine the effectiveness of a transdiagnostic group CBT for anxiety disorders program as a complement to treatment-as-usual (TAU) in primary mental health care. METHODS/DESIGN: The trial is a multicentre pragmatic randomized controlled trial with a pre-treatment, post-treatment, and follow-up at 4, 8 and 12-months design. Treatment and control groups. a) tCBT (12 weekly 2-h group sessions following a manualized treatment protocol); b) TAU for anxiety disorders. Inclusion criteria comprise meeting DSM-5 criteria for primary Panic Disorder, Agoraphobia, Social Anxiety Disorder and/or Generalized Anxiety Disorder. Patients are recruited in three regions in the province of Quebec, Canada. The primary outcome measures are the self-reported Beck Anxiety Inventory and the clinician-administered Anxiety and Related Disorders Interview Schedule for DSM-5 (ADIS-5); secondary outcome measures include treatment responder status based on the ADIS-5, and self-reported instruments for specific anxiety and depression symptoms, quality of life, functioning, and service utilisation. STATISTICAL ANALYSIS: Intention-to-treat analysis. A mixed effects regression model will be used to account for between- and within-subject variations in the analysis of the longitudinal effects of the intervention. DISCUSSION: This rigorous evaluation of tCBT in the real world will provide invaluable information to decision makers, health care managers, clinicians and patients regarding the effectiveness of the intervention. Widespread implementation of tCBT protocols in primary care could lead to better effectiveness, efficiency, access and equity for the large number of patients suffering from anxiety disorders that are currently not obtaining evidence-based psychotherapy.

BACKGROUND: The Geriatric Anxiety Inventory (GAI) and a short form of this instrument (GAI-SF) were developed to assess the severity of anxiety symptoms in older adults in order to compensate for the lack of validated screening tools adapted to the elderly population. This study examined the psychometric properties of the French Canadian version of the GAI, in its complete (GAI-FC) and short form (GAI-FC-SF). METHOD: A total of 331 community-dwelling seniors between 65 and 92 years old participated in this study. RESULTS: Both the GAI-FC and the GAI-FC-SF have sound psychometric properties with, respectively, a high internal consistency (α = .94 and .83), an adequate convergent validity (r = .50 to .86 with instruments known to evaluate constructs similar to the GAI or related to anxiety), a good test-retest reliability (r = .89 and .85), in addition to a single-factor structure. CONCLUSIONS: The results support the use of both the GAI-FC and the GAI-FC-SF. The GAI-FC-SF seems to be an interesting alternative to the GAI-FC as a screening tool when time available for assessment is limited.

BACKGROUND: Panic disorder with agoraphobia (PDA) and generalized anxiety disorder (GAD) are impairing and costly disorders that are often misdiagnosed and left untreated despite multiple consultations. These disorders frequently co-occur, but little is known about the costs associated with their comorbidity and the impact of cognitive-behavioral therapy (CBT) on cost reduction. AIMS OF THE STUDY: The first objective of this study was to assess the mental health-related costs associated with the specific concomitance of PDA and GAD. The second aim was to determine whether there is a reduction in direct and indirect mental health-related costs following conventional CBT for the primary disorder only (PDA or GAD) or combined CBT adapted to the comorbidity (PDA and GAD). METHODS: A total of 123 participants with a double diagnosis of PDA and GAD participated in this study. Direct and indirect mental health-related costs were assessed and calculated from a societal perspective at the pre-test, the post-test, and the three-month, six-month and one-year follow-ups. RESULTS: At the pre-test, PDA-GAD comorbidity was found to generate a mean total cost of CADUSD 2,000.48 (SD = USD 2,069.62) per participant over a three-month period. The indirect costs were much higher than the direct costs. Both treatment modalities led to significant and similar decreases in all cost categories from the pre-test to the post-test. This reduction was maintained until the one-year follow-up. DISCUSSION: Methodological choices may have underestimated cost evaluations. Nonetheless, this study supports the cost offset effects of both conventional CBT for primary PDA or GAD and combined CBT for PDA-GAD comorbidity. IMPLICATIONS FOR HEALTHCARE PROVISION AND USE: Treatment of comorbid and costly disorders with evidence-based treatments such as CBT may lead to considerable economic benefits for society. IMPLICATIONS FOR HEALTH POLICIES: Considering the limited resources of healthcare systems, it is important to make choices that will lead to better accessibility of quality services. The application of CBT for PDA, GAD or both disorders and training mental health professionals in this therapeutic approach should be encouraged. Additionally, it would be favorable for insurance plans to reimburse employees for expenses associated with psychological treatment for anxiety disorders. IMPLICATIONS FOR FURTHER RESEARCH: In addition to symptom reduction, it would be of great pertinence to explore which factors can contribute to reducing direct and indirect mental health-related costs.
