RESUMO

Cognitive behavioural therapy (CBT) including exposure and response prevention is the first-line psychological treatment for obsessive compulsive disorder (OCD). Given changes in the clinical landscape, there are increasing efforts to evaluate its effectiveness in online contexts. Mirroring the traditional in-person delivery, few studies have assessed the role of therapist-guided, manual-based CBT for OCD delivered in real-time via videoconferencing methods. The present study sought to fill this gap by comparing in-person and online delivery of group-based CBT for the treatment of OCD. A convenience sample of participants with moderate to severe OCD (n = 144) were recruited from a naturalistic database from two large OCD specialty assessment and treatment centres. Patients received group-based CBT that was provided in-person (pre-COVID-19 pandemic; March 2018 to March 2020) or online via videoconferencing (during the COVID-19 pandemic; March 2020 to April 2021). In both delivery methods, treatment consisted of 2-h weekly sessions led by trained clinicians. Analyses revealed that, regardless of treatment modality, both in-person and online groups demonstrated significant, reliable, and statistically equivalent improvements in OCD symptoms post-treatment. Videoconferenced, clinician-led CBT may be a promising alternative to in-person delivery for those with moderate to severe OCD symptoms.

RESUMO

OBJECTIVES: The current study examined whether cannabis use frequency and cannabis-related problem severity (as per the Cannabis Use Disorder Identification Test-Revised) predicted outcomes of cognitive behavioural therapy (CBT) for anxiety and related disorders. It was predicted that greater frequency of cannabis use and greater cannabis-related problem severity would be associated with dampened treatment outcomes compared to less severe cannabis use presentations. METHODS: Participants were 253 adults seeking treatment for anxiety and related disorders. Cannabis use was categorized as non-use (n = 135), infrequent use (using monthly to 4 times per month; n = 45), and frequent use (using 2 or more times per week; n = 73). Individuals who reported using cannabis completed cannabis use and cannabis-related problem measures before starting a CBT group. Participants also completed a weekly symptom-specific measure of anxiety symptoms throughout CBT. RESULTS: As hypothesized, frequent cannabis use was associated with poorer outcomes in CBT for anxiety and related disorders compared to non-use. Despite this, individuals who used cannabis frequently still experienced a statistically significant decrease in their anxiety symptoms from pre-to post-CBT, with a large effect size (d = -0.87). Cannabis-related problems was not a significant predictor of CBT outcomes. CONCLUSIONS: Cannabis use frequency was associated with poorer CBT outcomes for anxiety and related disorders, however these individuals still made notable treatment gains. The mechanism driving this relationship remains unclear. Future studies should attempt to replicate the current findings and examine possible mechanisms.

RESUMO

Recent meta-analyses highlight alterations in cognitive functioning among individuals with major depressive disorder (MDD), with performance deficits observed across multiple cognitive domains including executive functioning, memory, and attention. Moreover, impaired concentration is a formal diagnostic criterion for a major depressive episode. Notably, cognitive impairment is reported frequently in MDD and is associated with poor treatment response. Despite this knowledge, research examining the effectiveness of top-down, adjunctive treatments for cognitive dysfunction in MDD remains in its infancy. The primary aim of the present study was to perform a pilot investigation of the implementation of a standardized cognitive remediation program, Goal Management Training (GMT), among individuals with a primary diagnosis of MDD. A secondary aim was to explore how comorbid symptoms of post-traumatic stress disorder (PTSD) among those MDD patients exposed to trauma may affect treatment response. A final sample of thirty individuals were randomized to either participate in the nine-week GMT program (active group; n = 16) or to complete a nine-week waiting period (waitlist control; n = 14). One participant was excluded from the GMT group analysis following study completion due to meeting an exclusion criteria. In total, 60% of the individuals allocated to the GMT program were trauma exposed (n = 9). Groups were assessed at baseline, post-treatment, and at three-month follow-up. The assessment comprised neuropsychological tasks assessing a variety of cognitive domains, subjective measures of functioning and symptom severity, as well as a clinical interview to establish a primary diagnosis of MDD. Significant gains in processing speed, attention/concentration, and response inhibition were observed for the participants in the GMT condition relative to participants in the waitlist control condition. Individuals in the GMT condition also reported improvements in subjective cognitive functioning from baseline to post-treatment. Heightened PTSD symptom severity was associated with reduced response to treatment with respect to the domain of processing speed. The results of this pilot investigation highlight not only the potential utility of GMT as an augmentative treatment in MDD, but also highlight the contribution of comorbid symptoms of PTSD to diminished treatment response among trauma-exposed individuals with MDD. The study is limited primarily by its small pilot sample and the absence of a program evaluation component to gauge participant opinions and feedback of the treatment protocol.

RESUMO

OBJECTIVE: Telehealth is being increasingly incorporated into the delivery of mental health care and has received widespread attention during the COVID-19 pandemic for its ability to facilitate care during physical distancing restrictions. Videoconferencing is a common telehealth modality for delivering psychotherapy and has demonstrated similar outcomes to those of face-to-face therapy. Cognitive behavioural therapy (CBT) is the most common psychotherapy evaluated across various telehealth modalities; however, studies on CBT delivered via videoconference, particularly in a group therapy format, are lacking. Further, little research exists on videoconference group CBT for anxiety disorders. Accordingly, the present study compared the outcomes of group CBT for anxiety and related disorders delivered via videoconference versus face-to-face. METHOD: Using a non-randomized design, data on attendance, dropout, clinical outcomes, and functional impairment were collected from 413 adult outpatients of a tertiary care anxiety disorders clinic who attended a CBT group for panic disorder/agoraphobia, social anxiety disorder, generalized anxiety disorder (GAD), or obsessive-compulsive disorder delivered either face-to-face (pre-COVID-19 pandemic) or via videoconference (since the onset of COVID-19 pandemic). Outcomes were assessed using well-validated self-report measures. Data were collected pre-treatment, across 12 weekly sessions, and post-treatment. Intent-to-treat analyses were applied to symptom outcome measures. RESULTS: Face-to-face CBT conferred only a slight benefit over videoconference CBT for symptom outcomes across all groups, but when assessed individually, only the GAD group showed greater symptom improvement in the face-to-face format. Effect sizes for significant differences between the delivery formats were small. Participants in videoconference groups tended to have slightly higher attendance rates in some instances, whereas functional improvement and treatment dropout were comparable across the delivery formats. CONCLUSIONS: Results provide preliminary evidence that videoconference group CBT for anxiety and related disorders may be a promising and effective alternative to face-to-face CBT. Additional research is needed to establish equivalence between these delivery formats.

RESUMO

The Posttraumatic Stress Disorder (PTSD) Checklist for DSM-5 (PCL-5) is a widely used, self-report measure that is employed to assess PTSD symptom severity and determine the presence of probable PTSD in various trauma-exposed populations. The PCL-5 is often administered in clinical settings as a screening tool for PTSD, with a suggested cutoff score of 33 indicating a probable PTSD diagnosis. Recent research indicates that a higher cutoff may be required in psychiatric samples. In the present study, we aimed to determine the sensitivity and specificity of the PCL-5 in a Canadian outpatient psychiatric sample and establish an optimal cutoff score for detecting probable PTSD in this sample. Participants were 673 individuals who reported a history of trauma exposure and were assessed using a semistructured interview and self-report measures. Individuals diagnosed with PTSD (N = 193) reported a mean PCL-5 score of 56.57, whereas individuals without PTSD (N = 480) reported a mean score of 33.56. A score of 45 was determined to be the optimal cutoff score in this sample, balancing sensitivity and specificity while detecting a probable diagnosis of PTSD. Consistent with findings in other psychiatric samples, these findings indicate that in an outpatient psychiatric sample with a history of exposure to a variety of trauma types, a higher cutoff score is required to determine probable PTSD. In addition, given the estimated rate of false positives even with a higher cutoff, follow-up diagnostic assessments are recommended.

RESUMO

Emotion regulation difficulties (difficulty regulating the experience, occurrence, and expression of emotions) are associated with the severity of posttraumatic stress disorder (PTSD) symptoms across trauma types (e.g., childhood abuse, sexual assault, combat trauma). Despite emerging research suggesting that evidence-based treatments for PTSD, including cognitive processing therapy (CPT), are effective in improving emotion regulation difficulties, some have argued that these therapies may not be as safe or acceptable to patients compared to non-trauma focused treatments. Accordingly, the current study sought to determine the impact of pre-treatment emotion regulation difficulties on PTSD treatment outcomes and dropout, as well as whether emotion regulation difficulties improve over the course of treatment with group CPT among individuals with PTSD. One hundred and one individuals with PTSD participated in group CPT. Repeated measures t-tests found significant pre- to post-treatment improvements for emotion regulation difficulties (d = .79). Further, hierarchical linear modeling and logistic regression analyses revealed that pre-treatment emotion regulation difficulties were neither significantly associated with changes in PTSD symptoms over the course of treatment (d = -.07) nor with treatment dropout (OR = 1.00). These findings suggest that CPT delivered in a group setting to individuals with PTSD can lead to significant improvement in emotion regulation and that emotion regulation difficulties do not negatively impact treatment outcome or patient retention.

RESUMO

Executive functions (EF) deficits are hypothesized to be a core contributor to hoarding symptoms. EF have been studied in adult hoarding populations, but studies in youth are lacking. The current study compared multiple EF subdomains between youth with obsessive-compulsive disorder (OCD) and youth with OCD and hoarding symptoms. Forty youth (8-18 years old) with a primary diagnosis of OCD were recruited. Participants were divided by hoarding severity on the Child Saving Inventory (CSI) into either the "hoarding group" (upper 33.3%) or the "low-hoarding group" (lower 66.7%). Groups were compared on EF tasks of cognitive flexibility, decision-making, and inhibitory control. Youth in the hoarding group exhibited significantly higher cognitive flexibility and lowered perseveration than the low-hoarding group. Hoarding and low-hoarding groups did not differ in any other EF subdomain. Hoarding symptoms in youth with OCD were not associated with deficits in EF subdomains; instead, youth who hoard exhibited higher cognitive flexibility compared to youth with low hoarding symptoms.

RESUMO

BACKGROUND: Recent meta-analyses point towards cognitive impairments in obsessive-compulsive disorder (OCD), particularly in such executive function subdomains as planning and organization. Scant attention has focused on cognitive remediation strategies that may reduce cognitive dysfunction, with a possible corresponding decrease in symptoms of OCD. OBJECTIVE: The aim of this study was to assess the implementation of a standardized cognitive remediation program, Goal Management Training (GMT), in a pilot sample of individuals with OCD. METHOD: Nineteen individuals with a primary DSM-5 diagnosis of OCD were randomized to receive either the 9-week GMT program (active group; n = 10) or to complete a 9-week waiting period (waitlist control; n = 9). Groups were assessed at baseline, post-treatment, and 3-month follow-up. The assessment comprised neuropsychological tasks assessing a variety of cognitive domains, and subjective measures of functioning and of symptom severity. RESULTS: The active condition showed significant improvements from baseline to post-treatment on measures of inattention, impulsivity, problem-solving, and organization compared to controls. Moreover, whereas the active group reported a significant improvement in subjective cognition over the course of treatment, no such improvement emerged in the waitlist group over this same period. Neither group showed improvement on indices of depressive, anxiety, or OCD-related symptom severity. DISCUSSION: The results of this small pilot investigation indicate that, although promising, this protocol requires several modifications to be best suited for this population. Replication of these findings is awaited, with current results potentially limited by sample characteristics including motivation to seek and complete treatment, and high attrition at 3-month follow-up (n = 6 completers). TRIAL REGISTRATION: NCT02502604. (December 7, 2018).

RESUMO

Introduction: Obsessive-compulsive disorder (OCD) is a heterogeneous disorder, with multiple symptom presentations. Delineating the neuropsychological characteristics associated with previously identified symptom clusters may therefore be useful in assisting to better define symptom subtypes of OCD.Areas covered: This review summarizes the existing literature on the assessment of neuropsychological performance in symptom-based dimensions of OCD. Results of 23 studies are described and the methodological issues and challenges present in this body of literature are discussed.Expert opinion: The current state of the literature precludes a meaningful meta-analysis of cognitive dysfunction across the breadth of symptom dimensions of OCD. This is due primarily to significant methodological differences observed between studies, both in terms of neuropsychological measures and symptom subtyping methods employed, and any resulting meta-analytic results would be biased by varying quality of evidence. Future studies addressing these limitations should include more consistent neuropsychology measures and methods of classifying OCD symptoms with the aim of reproducing the results of previous research to identify more concrete patterns of neuropsychological performance across dimensions; best practices and alternative approaches are discussed.

RESUMO

Objectives: To review qualitative research on the specific challenges and strategies that relate to driving cessation for older adults with dementia, from the perspectives of key informant groups.Method: A meta-synthesis of qualitative studies was conducted. Structured inclusion criteria were applied to screen 616 titles and abstracts, and 9 qualitative studies were included, published from 2002 to 2016. Descriptive themes were identified using content analysis and synthesized to generate analytic themes.Results: The study samples and methodologies represented a diverse range. Cross-cutting themes on experiences of driving cessation for people with dementia are the: importance of open communication and autonomy in decision-making, and advanced planning to connect people with resources; significance of relationships; importance of providing support for the impact of cessation on identity and emotional wellbeing; and benefit of individualizing supportive approaches.Conclusion: This review identifies some important areas for consideration when designing supportive programs to address driving.Clinical Implications: Interventions to support driving cessation for people with dementia should prioritize support for communication, advanced planning, and emotional effects of stopping driving.

RESUMO

A growing body of literature suggests that obsessive-compulsive disorder (OCD) is a heterogeneous condition. The studies investigating symptom dimensions have been limited by numerous methodological differences and sample characteristics. The purpose of this study was to compare the two most commonly applied statistical techniques used in addressing this question in the same large cohort of individuals with OCD. Both cluster analysis and factor analysis were used to examine OCD symptom data as measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) Symptom Checklist for 355 individuals with a primary diagnosis of OCD. The factor analysis revealed a three-factor model best described as symmetry obsessions/ordering compulsions, contamination obsessions/cleaning compulsions and aggressive obsessions/checking compulsions. In contrast, the cluster analysis yielded a stable four-cluster solution best described as symmetry obsessions/ordering compulsions, contamination obsessions/cleaning compulsions, aggressive-somatic-religious obsessions/checking compulsions and a mixed symptom profile. Although there was overlap in the models resulting from these two statistical approaches, cluster analysis better captured the dimensional nature of OCD by demonstrating the prevalence of symptom categories in each subgroup. Though both analyses are capable of providing similar outputs, the validity of these results is limited given the input of a priori symptom categories from the Y-BOCS.

RESUMO

BACKGROUND: The study of seasonal patterns of public interest in psychiatric disorders has important theoretical and practical implications for service planning and delivery. The recent explosion of internet searches suggests that mining search databases yields unique information on public interest in mental health disorders, which is a significantly more affordable approach than population health studies. OBJECTIVE: This study aimed to investigate seasonal patterns of internet mental health queries in Ontario, Canada. METHODS: Weekly data on health queries in Ontario from Google Trends were downloaded for a 5-year period (2012-2017) for the terms "schizophrenia," "autism," "bipolar," "depression," "anxiety," "OCD" (obsessive-compulsive disorder), and "suicide." Control terms were overall search results for the terms "health" and "how." Time-series analyses using a continuous wavelet transform were performed to isolate seasonal components in the search volume for each term. RESULTS: All mental health queries showed significant seasonal patterns with peak periodicity occurring over the winter months and troughs occurring during summer, except for "suicide." The comparison term "health" also exhibited seasonal periodicity, while the term "how" did not, indicating that general information seeking may not follow a seasonal trend in the way that mental health information seeking does. CONCLUSIONS: Seasonal patterns of internet search volume in a wide range of mental health terms were observed, with the exception of "suicide." Our study demonstrates that monitoring internet search trends is an affordable, instantaneous, and naturalistic method to sample public interest in large populations and inform health policy planners.

RESUMO

BACKGROUND: Driving in persons with dementia poses risks that must be counterbalanced with the importance of the care for autonomy and mobility. Physicians often find substantial challenges in the assessment and reporting of driving safety for persons with dementia. This paper describes a driving in dementia decision tool (DD-DT) developed to aid physicians in deciding when to report older drivers with either mild dementia or mild cognitive impairment to local transportation administrators. METHODS: A multi-faceted, computerized decision support tool was developed, using a systematic literature and guideline review, expert opinion from an earlier Delphi study, as well as qualitative interviews and focus groups with physicians, caregivers of former drivers with dementia, and transportation administrators. The tool integrates inputs from the physician-user about the patient's clinical and driving history as well as cognitive findings, and it produces a recommendation for reporting to transportation administrators. This recommendation is translated into a customized reporting form for the transportation authority, if applicable, and additional resources are provided for the patient and caregiver. CONCLUSIONS: An innovative approach was needed to develop the DD-DT. The literature and guideline review confirmed the algorithm derived from the earlier Delphi study, and barriers identified in the qualitative research were incorporated into the design of the tool.

RESUMO

OBJECTIVE: The aim of this project was to review the literature on interventions aimed at facilitating driving cessation in older adults, with and without dementia. METHODS: A literature search was performed using the databases MEDLINE, CINAHL, Cochrane Central, Embase, and PsycINFO, from 1994 to September 2014. Two independent raters screened articles for inclusion and extracted study data. We only included articles if they directly addressed the topic of intervention approaches to facilitate the process of driving cessation in older adults or to support the adaptation of older adults who have had to stop driving and included a control group. RESULTS: Of an initial 477 unique records identified, 111 pertained to driving cessation in older adults, and only three articles were controlled trials of intervention approaches related to driving cessation. One article described an intervention for retired drivers with dementia, while another was aimed at caregivers of drivers with dementia, and the third included retired and retiring drivers without dementia. Outcomes such as reduced depressive symptoms, increased trips out of home, and efficacy in dealing with the driving cessation process were positive, but the specific outcome measures and magnitude of effects varied across studies. CONCLUSIONS: Although the results summarized in this review point toward potentially promising effects of interventions for facilitating driving cessation in older adults, these findings must be interpreted with caution given the significant methodological limitations of the studies, including small samples, participant attrition, lack of blinding, and non-validated outcome measures.

RESUMO

With an increasing number of older drivers who are prescribed antidepressants, the potential consequences of antidepressant use on driving skills in an aging population are becoming a pressing issue. We conducted a systematic review using MEDLINE, targeting articles specifically pertaining to antidepressants and driving in a population or subgroup of older adults (≥ 55 years of age). The search yielded 267 references, nine of which pertained to the effects of antidepressants on driving in older adults. The single experimental study found imipramine to have detrimental effects on highway driving, whereas nefazodone did not. Seven of eight population-based studies reported a significant increased risk of involvement in a collision associated with antidepressant use. Although the studies indicated a negative effect of antidepressants on driving, the epidemiological designs cannot exclude the possibility that the underlying illness, generally major depression, is the culprit.
