Effectiveness of cognitive behavioural therapy for anxiety and depression in primary care: a meta-analysis

Control your emotions: evidence for a shared mechanism of cognitive and emotional control

The current investigation examined the bidirectional effects of cognitive control and emotional control and the overlap between these two systems in regulating emotions. Based on recent neural and cognitive findings, we hypothesised that two control systems largely overlap as control recruited for one system (either emotional or cognitive) can be used by the other system. In two experiments, participants completed novel versions of either the Stroop task (Experiment 1) or the Flanker task (Experiment 2) in which the emotional and cognitive control systems were actively manipulated into either a high or low emotional-load condition (achieved by varying the proportions of negative-valence emotional cues) and a high and a low cognitive control condition (achieved through varying the proportion of conflict-laden trials). In both experiments, participants' performance was impaired when both emotional and cognitive control were low, but significantly and similarly improved when one of the two control mechanisms were activated - the emotional or the cognitive. In Experiment 2, performance was further improved when both systems were activated. Our results give further support for a more integrative notion of control in which the two systems (emotional and cognitive control) not only influence each other, but rather extensively overlap.

A systematic review and meta-analysis of transdiagnostic interventions for common mental disorders in primary care

OBJECTIVE

In primary care, treating common mental disorders according to the ICD or DSM is challenging. A transdiagnostic approach may facilitate the management of mental health problems by treating across psychiatric diagnoses. This meta-analysis aims to identify and compare transdiagnostic interventions delivered in primary care and to determine the effectiveness of these interventions, focusing on common mental disorders.

METHODS

A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted by searching the databases Medline, Embase, Web of Science, and PsycINFO. Standardized mean differences (SMD) were calculated for the outcomes, and additional subgroup analyses were performed.

RESULTS

From an initial set of 10,618 RCTs, 38 studies were included and retained for data extraction. Transdiagnostic interventions led to a significant reduction in symptoms of depression (SMD: -0.38) and anxiety (SMD: - 0.47). Treatment outcomes for somatoform disorders were not significant (SMD: - 0.22). About half of the interventions were provided by health professionals not specifically trained in psychotherapy; these interventions also proved to be effective (depression: SMD: -0.47; anxiety: -0.39).

CONCLUSION

This meta-analysis supports the use of transdiagnostic interventions for common mental disorders in primary care. Transdiagnostic interventions carried out by medical and health professionals not specifically trained in psychotherapy are feasible in PC, but emphasis should be placed on adequate training for them.

Evaluation and Future Challenges in a Self-Guided Web-Based Intervention With and Without Chat Support for Depression and Anxiety Symptoms During the COVID-19 Pandemic: Randomized Controlled Trial

BACKGROUND

The COVID-19 pandemic has had an impact on mental health worldwide. Low- and middle-income countries were largely affected by it. Mexico was one of the most affected countries. Extended periods of lockdowns, isolation, and social distancing, among other factors, highlighted the need to introduce web-based psychological interventions to the Mexican population. In this context, Mental Health COVID-19 emerged as a self-guided web-based intervention (SGWI) aimed at adults to improve mental health during the COVID-19 pandemic.

OBJECTIVE

This study aims to assess the efficacy of 2 modalities of a self-guided intervention (with and without chat support) in reducing depression symptoms, generalized anxiety, community posttraumatic stress, widespread fear, anxiety, sleep quality, physiological and affective coping, and suicide ideation. In addition, it aimed to compare the moderating role of coping strategies, acceptance, and satisfaction in participants' symptom reduction. We hypothesize that the self-guided, chat-supported modality will show higher efficacy than the modality without chat support in achieving clinical change and better performance as a moderator of depression symptoms, generalized anxiety, community posttraumatic stress, widespread fear, anxiety, sleep quality, physiological and affective coping, and suicide ideation, as well as an increase in participants' satisfaction and acceptability.

METHODS

A randomized controlled trial was conducted. Data were collected from May 2020 to June 2022. We performed intrasubject measures at 4 evaluation periods: pretest, posttest, and follow-up measurements at 3 and 6 months. Differences between intervention groups were assessed through the Mann-Whitney U test for continuous variables and the chi-square test for categorical variables. Changes due to intervention were analyzed using Wilcoxon W test. Moderated regression analysis was performed to test the hypothesized moderating role of coping strategies, usability, and opinion about treatment on clinical change.

RESULTS

A total of 36 participants completed the intervention; of these, 5 (14%) were part of the SGWI group, and 31 (86%) were on the SGWI plus chat support (SGWI+C) group, which included a chat service with therapists. The perceived high complexity of the system for the SGWI group had a moderating effect associated with a lack of efficacy of the intervention regarding depression, but not when controlled for sociodemographic variables. A perception of lower helpfulness of the intervention was associated with poorer outcomes. Coping strategies did not show moderating effects.

CONCLUSIONS

Enhancing the utility of web-based interventions for reducing clinical symptoms by incorporating a support chat to boost treatment adherence seemed to improve the perception of the intervention's usefulness. Web-based interventions face several challenges, such as eliminating complexities in platform use and increasing the users' perceived utility of the intervention, among other issues identified in the study.

The role of symptom reduction in improving health-related quality of life through brief cognitive behavioral therapy

Brief cognitive behavior therapy (bCBT) is effective in reducing symptoms of depression and anxiety disorders and improving health-related quality of life (HRQoL). However, the mechanisms through which cognitive behavior therapy impact HRQoL are not well understood. This study evaluated whether anxiety and depression symptom reduction is a mechanism of treatment for HRQoL outcomes.

METHOD

Using secondary data from a multisite, pragmatic, randomized trial, this study evaluated bCBT vs enhanced usual care in 16 VA community-based outpatient clinics. Ordinary least-squares path analysis testing multiple mediators was used to evaluate the role of change in depression and anxiety symptoms in the relationship between treatment condition and HRQoL.

RESULTS

Receiving bCBT (vs. enhanced usual care) was significantly negatively associated with change (reduction) in depression and anxiety scores. The indirect effect of treatment on mental HRQoL was significant with change in depression scores as mediator. A similar pattern was observed for physical HRQoL and change in anxiety scores as mediator.

CONCLUSION

Findings suggest reduction of depression and anxiety symptoms as a mechanism through which bCBT for depression promoted improvements in HRQoL, with important implications for understanding how CBT impacts functioning, as well as the utility of bCBT in nontraditional mental health settings.

Nurturing an organizational context that supports team-based primary mental health care: A grounded theory study

BACKGROUND

The expansion of the Patient-Centred Medical Home model presents a valuable opportunity to enhance the integration of team-based mental health services in primary care settings, thereby meeting the growing demand for such services. Understanding the organizational context of a Patient-Centred Medical Home is crucial for identifying the facilitators and barriers to integrating mental health care within primary care. The main objective of this paper is to present the findings related to the following research question: "What organizational features shape Family Health Teams' capacity to provide mental health services for depression and anxiety across Ontario, Canada?"

METHODS

Adopting a constructivist grounded theory approach, we conducted interviews with various mental health care providers, and administrators within Ontario's Family Health Teams, in addition to engaging provincial policy informants and community stakeholders. Data analysis involved a team-based approach, including code comparison and labelling, with a dedicated data analysis subcommittee convening monthly to explore coded concepts influencing contextual factors.

RESULTS

From the 96 interviews conducted, involving 82 participants, key insights emerged on the organizational contextual features considered vital in facilitating team-based mental health care in primary care settings. Five prominent themes were identified: i) mental health explicit in the organizational vision, ii) leadership driving mental health care, iii) developing a mature and stable team, iv) adequate physical space that facilitates team interaction, and v) electronic medical records to facilitate team communication.

CONCLUSIONS

This study underscores the often-neglected organizational elements that influence primary care teams' capacity to deliver quality mental health care services. It highlights the significance of strong leadership complemented by effective communication and collaboration within teams to enhance their ability to provide mental health care. Strengthening relationships within primary care teams lies at the core of effective healthcare delivery and should be leveraged to improve the integration of mental health care.

Internet-delivered transdiagnostic psychological treatments for individuals with depression, anxiety or both: a systematic review with meta-analysis of randomised controlled trials

OBJECTIVE

Depression and anxiety are major public health problems. This study evaluated the effects of internet-delivered transdiagnostic psychological treatments for individuals with depression, anxiety, or both.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

Medline (Ovid), Cochrane Library (Wiley), the Web of Science Core Collection (Clarivate), and PsycInfo (EBSCO) were searched on 24 May 2021, with an update on 6 February 2023.

ELIGIBILITY CRITERIA

Randomised controlled trials of internet-delivered transdiagnostic psychological treatments, open to both participants with primary depression and participants with primary anxiety. This review concerned all treatment frameworks, both guided and unguided formats and all age groups.

DATA EXTRACTION AND SYNTHESIS

In random-effects meta-analysis, we estimated pooled effects on depression symptoms and anxiety in terms of Hedges' g with 95% CIs. Absolute and relative heterogeneity was quantified as the τ2 and I 2.

RESULTS

We included 57 trials with 21 795 participants. Nine trials (16%) recruited exclusively from routine care, and three (5%) delivered treatment via video. For adults, large within-group reductions were seen in depression (g=0.90; 95% CI 0.81 to 0.99) and anxiety (g=0.87; 95% CI 0.78 to 0.96). Compared with rudimentary passive controls, the added effects were moderate (depression: g=0.52; 95% CI 0.42 to 0.63; anxiety: g=0.45; 95% CI 0.34 to 0.56) and larger in trials that required all participants to meet full diagnostic criteria for depression or an anxiety disorder. Compared with attention/engagement controls, the added effects were small (depression: g=0.30; 95% CI 0.07 to 0.53; anxiety: g=0.21; 95% CI 0.01 to 0.42). Heterogeneity was substantial, and the certainty of the evidence was very low. Two trials concerned adolescents and reported mixed results. One trial concerned older adults and reported promising results.

CONCLUSION

Internet-delivered transdiagnostic treatments for depression and anxiety show small-to-moderate added effects, varying by control condition. Research is needed regarding routine care, the video format, children and adolescents and older adults.

Interventions to reduce burnout and improve the mental health of nurses during the COVID-19 pandemic: A systematic review of randomised controlled trials with meta-analysis

This systematic review aims to investigate and determine the effectiveness of interventions on improving mental health (anxiety, depression, stress or mental well-being) and/or reducing burnout of nurses working in hospitals during the COVID-19 pandemic. A search was conducted on studies from conception to December 2022 in databases: PubMed, Embase, Cochrane Central Register of Controlled Trials, CINAHL, PsycINFO, Scopus and Web of Science and in ProQuest Thesis & Dissertations Global Database, Google Scholar and ClinicalTrials.gov. A total of 17 randomised controlled trials that evaluated different interventions were included. The outcomes were anxiety (n = 11), depression (n = 5), stress (n = 13) mental well-being (n = 7) and burnout (n = 7). Not all interventions led to positive outcomes. Grading of Recommendations Assessment, Development and Evaluation (GRADE) appraisal and risk of bias assessment using the Cochrane tool for randomised controlled trials (RoB 2.0) revealed poor quality of currently available literature, with low to very low certainty. Meta-analysis showed high heterogeneity among the five different outcomes, with subgroup analysis showing greater success in interventions conducted on nurses involved in the care of COVID-19 patients. More well-designed trials are necessary to reinforce current evidence to improve the mental health of nurses, to not only protect their quality of life but also to ensure the quality of patient care.

Efficacy of an Electronic Cognitive Behavioral Therapy Program Delivered via the Online Psychotherapy Tool for Depression and Anxiety Related to the COVID-19 Pandemic: Pre-Post Pilot Study

BACKGROUND

Lockdowns and social distancing resulting from the COVID-19 pandemic have worsened the population's mental health and made it more difficult for individuals to receive care. Electronic cognitive behavioral therapy (e-CBT) is a cost-effective and evidence-based treatment for anxiety and depression and can be accessed remotely.

OBJECTIVE

The objective of the study was to investigate the efficacy of online psychotherapy tailored to depression and anxiety symptoms during the pandemic.

METHODS

The pilot study used a pre-post design to evaluate the efficacy of a 9-week e-CBT program designed for individuals with depression and anxiety affected by the pandemic. Participants were adults (N=59) diagnosed with major depressive disorder and generalized anxiety disorder, whose mental health symptoms initiated or worsened during the COVID-19 pandemic. The online psychotherapy program focused on teaching coping, mindfulness, and problem-solving skills. Symptoms of anxiety and depression, resilience, and quality of life were assessed.

RESULTS

Participants demonstrated significant improvements in symptoms of anxiety (P=.02) and depression (P=.03) after the intervention. Similar trends were observed in the intention-to-treat analysis. No significant differences were observed in resilience and quality-of-life measures. The sample comprised mostly females, making it challenging to discern the benefits of the intervention in males. Although a pre-post design is less rigorous than a controlled trial, this design was selected to observe changes in scores during a critical period.

CONCLUSIONS

e-CBT for COVID-19 is an effective and accessible treatment option. Improvements in clinical symptoms of anxiety and depression can be observed in individuals whose mental health is affected by the COVID-19 pandemic.

Effectiveness of physical activity interventions for improving depression, anxiety and distress: an overview of systematic reviews

OBJECTIVE

To synthesise the evidence on the effects of physical activity on symptoms of depression, anxiety and psychological distress in adult populations.

DESIGN

Umbrella review.

DATA SOURCES

Twelve electronic databases were searched for eligible studies published from inception to 1 January 2022.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Systematic reviews with meta-analyses of randomised controlled trials designed to increase physical activity in an adult population and that assessed depression, anxiety or psychological distress were eligible. Study selection was undertaken in duplicate by two independent reviewers.

RESULTS

Ninety-seven reviews (1039 trials and 128 119 participants) were included. Populations included healthy adults, people with mental health disorders and people with various chronic diseases. Most reviews (n=77) had a critically low A MeaSurement Tool to Assess systematic Reviews score. Physical activity had medium effects on depression (median effect size=-0.43, IQR=-0.66 to -0.27), anxiety (median effect size=-0.42, IQR=-0.66 to -0.26) and psychological distress (effect size=-0.60, 95% CI -0.78 to -0.42), compared with usual care across all populations. The largest benefits were seen in people with depression, HIV and kidney disease, in pregnant and postpartum women, and in healthy individuals. Higher intensity physical activity was associated with greater improvements in symptoms. Effectiveness of physical activity interventions diminished with longer duration interventions.

CONCLUSION AND RELEVANCE

Physical activity is highly beneficial for improving symptoms of depression, anxiety and distress across a wide range of adult populations, including the general population, people with diagnosed mental health disorders and people with chronic disease. Physical activity should be a mainstay approach in the management of depression, anxiety and psychological distress.

Exploring Fear of Cancer Recurrence (FCR) in cancer survivors from a medical social work perspective: A qualitative study of medical social workers in South Korea

BACKGROUND

Fear of Cancer Recurrence (FCR) in cancer survivors has been insufficiently addressed despite its imperativeness in cancer journey. Although several studies have investigated healthcare professionals' experience with FCR in cancer survivors, a medical social work perspective has rarely been reflected. This study aimed to explore Korean medical social workers' experience with intervening FCR in cancer survivors.

METHODS

Snowball sampling recruited 12 experienced medical social workers intervening with cancer survivors at tertiary or university cancer hospitals in South Korea. Individual and focus-group interviews (FGI) were conducted with the medical social workers. The interviews were recorded, transcribed, and analyzed by using an inductive qualitative content analysis.

RESULTS

Content analysis of the interviews extracted the following major themes regarding FCR in cancer survivors. First, when and how FCR among cancer survivors emerged at the early stage of medical social work interventions was identified. Second, how medical social workers dealt with FCR in cancer survivors was illustrated. Third, the responses of cancer survivors to medical social work interventions for FCR were assessed. Finally, the internal and external issues underlying the medical social work interventions for FCR among cancer survivors were revealed and discussed.

CONCLUSION

Based on the results, this study suggested the implications on dealing with FCR in cancer survivors in the realm of medial social work profession. Furthermore, it expanded the discussion about FCR in cancer survivors from cancer hospitals to community.

Risk factors and digital interventions for anxiety disorders in college students: Stakeholder perspectives

The worldwide prevalence of anxiety disorders among college students is high, which negatively affects countries, schools, families, and individual students to varying degrees. This paper reviews the relevant literature regarding risk factors and digital interventions for anxiety disorders among college students from the perspectives of different stakeholders. Risk factors at the national and societal levels include class differences and the coronavirus disease 2019 pandemic. College-level risk factors include the indoor environment design of the college environment, peer relationships, student satisfaction with college culture, and school functional levels. Family-level risk factors include parenting style, family relationship, and parental level of education. Individual-level risk factors include biological factors, lifestyle, and personality. Among the intervention options for college students' anxiety disorders, in addition to traditional cognitive behavioral therapy, mindfulness-based interventions, psychological counseling, and group counseling, digital mental health interventions are increasingly popular due to their low cost, positive effect, and convenient diagnostics and treatment. To better apply digital intervention to the prevention and treatment of college students' anxiety, this paper suggests that the different stakeholders form a synergy among themselves. The nation and society should provide necessary policy guarantees, financial support, and moral and ethical supervision for the prevention and treatment of college students' anxiety disorders. Colleges should actively participate in the screening and intervention of college students' anxiety disorders. Families should increase their awareness of college students' anxiety disorders and take the initiative to study and understand various digital intervention methods. College students with anxiety disorders should actively seek psychological assistance and actively accept and participate in digital intervention projects and services. We believe that in the future, the application of methods such as big data and artificial intelligence to improve digital interventions and provide individualized treatment plans will become the primary means of preventing and treating anxiety disorders among college students.

Using the common-sense model to explicate the role of illness representation in self-care behaviours and anxiety symptoms among patients with Type 2 diabetes

OBJECTIVES

Based on the common-sense model of self-regulation, this study aimed to explicate the mechanism underlying the effect of illness representations on self-care behaviours and anxiety symptoms among patients with type 2 diabetes.

METHODS

A telephone survey was administered to 473 patients in Hong Kong. Structural equation modelling was used to test if threat and control perceptions regarding diabetes would be associated with self-reported self-care behaviours and anxiety symptoms through adoption of adaptive/maladaptive coping strategies and diabetes-related self-efficacy.

RESULTS

Control perceptions but not threat perceptions were positively associated with self-care behaviours. Control perceptions had a positive indirect association with self-care behaviours through more problem-focused coping and diabetes-related self-efficacy. Threat perceptions simultaneously had a positive indirect association through more problem-focused coping and a negative indirect association through more avoidant coping and lower diabetes-related self-efficacy. In contrast, threat and control perceptions were positively and negatively, respectively, associated with anxiety symptoms. Problem-focused and avoidant coping consistently mediated the indirect association between threat perceptions and anxiety symptoms.

CONCLUSION

Threat and control perceptions were associated with diabetes self-care behaviours and anxiety symptoms through different self-regulation pathways.

PRACTICE IMPLICATIONS

Our findings inform possible targets for self-management interventions to simultaneously enhance self-care behaviours and alleviate diabetes-associated anxiety.

Exploring service users experiences of remotely delivered CBT interventions in primary care during COVID-19: An interpretative phenomenological analysis

Primary Care Mental Health Services (PMHCS) aim to provide accessible and effective psychological interventions. However, there is a scarcity of qualitative research focused on patients' experiences. Service users' experience can inform development of accessible, high-quality mental health services. Nine semi-structured interviews were analysed from Primary Care Mental Health users in Northern Scotland using Interpretative Phenomenological Analysis (IPA). Four superordinate themes were generated: Orientating to treatment, Intervention features, Change enablers, and Impact. The results identified both facilitators and barriers associated with access and psychological change; and narratives around CBT acceptability, outcomes and remote delivery. The role of GPs emerged as a key determinant of access to PMHCS. The therapeutic relationship contributed to person-centred care provision, idiosyncratic change processes and self-empowerment. A personal commitment to engage with homework was described as a crucial change enabler. Findings are discussed in relation to existing literature, practical implications and suggestions for future research.

The Integration of Behavioral Health and Primary Care for Hispanic/Latino Patients with Depression and Comorbid PTSD

Comorbid PTSD and depression are notably high within primary care settings serving low-income and/or immigrant Hispanic/Latino populations. There is limited research examining how comorbid PTSD impacts the response to depression treatment for patients within these settings. The purpose of this study was to examine PTSD-depression comorbidity and its association with treatment outcomes among Hispanic/Latino patients enrolled in an integrated behavioral health intervention for depression. Participants were Hispanic/Latino adult primary care patients who met the criteria for depression and were not currently in treatment. Depression and anxiety severity were assessed at baseline and the 6 and 12 month follow-ups. Outcomes were compared between participants who met the criteria for a PTSD diagnosis and those that did not. Depression and anxiety scores significantly decreased through the 1-year intervention period regardless of PTSD diagnosis. More research is needed to understand what elements of culturally adapted, linguistically concordant treatment benefit diverse patients the most.

Effects of Urban Forest Therapy Program on Depression Patients

Depression is a common serious mental health condition that can have negative personal and social consequences, and managing it is critical for treating depression patients. Forest therapy is emerging as a promising non-pharmacological intervention to improve mental health. However, although the effectiveness of forest therapy programs using forests far from the city has been proven, it is not well known that urban forests can be easily accessed in daily life. Therefore, this study aimed to examine the effects of an urban forest therapy program on depression symptoms, sleep quality, and somatization symptoms of depression patients. To evaluate this, a randomized controlled trial (RCT) design was employed. A total of 47 depression patients participated in this study (22 in the urban forest therapy program group and 25 in the control group). The Beck Depression Inventory (BDI), the Hamilton Rating Scale for Depression (HRSD), the Pittsburgh Sleep Quality Index (PSQI), and the Patient Health Questionnaire-15 (PHQ-15) were administered to each participant to assess the effects of the urban forest therapy program. The results of this study revealed that depression patients in the urban forest therapy program had significantly alleviated depression symptoms and improved sleep quality and somatization symptoms compared to the control group. In conclusion, this study demonstrates the possibility that the urban forest therapy program could be used as an effective non-pharmacological treatment to alleviate depression disorder.

A cross-sectional study on fatigue, anxiety, and symptoms of depression and their relation with medical status in adult patients with Marfan syndrome. Psychological consequences in Marfan syndrome

Marfan syndrome (MFS) is a connective tissue disorder affecting the cardiovascular, ocular, and skeletal system, which may be accompanied by psychological features. This study aimed to determine the prevalence of fatigue, anxiety, and symptoms of depression in MFS patients, and to assess the degree to which sociodemographic and clinical variables are associated with fatigue and psychological aspects. The prevalence of fatigue, anxiety, and symptoms of depression were assessed in two cohorts of MFS patients and compared with healthy controls. The checklist individual strength (CIS), and hospital anxiety and depression scale (HADS) questionnaires were utilized. Medical status was assessed (family history of MFS, aortic root dilatation >40 mm, previous aortic surgery, aortic dissection, chronic pain, skeletal involvement, and scoliosis). Severe fatigue was experienced by 37% of the total MFS cohort (n = 155). MFS patients scored significantly higher on the CIS questionnaire, concerning severe fatigue, as compared with the general Dutch population (p < 0.0001). There were no differences in HADS anxiety or depression scores. In older MFS patients, with a more severe cardiovascular phenotype, chronic pain, and a higher unemployment rate, significantly more symptoms of depression were observed, when compared with the general population (p = 0.027) or compared with younger MFS patients (p = 0.026). Multivariate analysis, showed that anxiety was associated with chronic pain (p = 0.022) and symptoms of depression with unemployment (p = 0.024). MFS patients report significantly more severe fatigue as compared with the general population. Since the cause of fatigue is unclear, more research may be needed. Psychological intervention, for example, cognitive behavioral therapy, may contribute to a reduction in psychological symptoms.

Long-term outcomes at 24- and 36-month follow-up in the intervention arm of the randomized controlled trial of Prompt Mental Health Care

BACKGROUND

Whether long-term symptom improvement is maintained after treatment in services such as the Norwegian Prompt Mental Health Care (PMHC) and the English Improving Access to Psychological Therapies is not yet known. In this prospective study, we investigate whether improvements observed at 6-month follow-up are maintained at 24- and 36-month follow-up among clients who received PMHC.

METHOD

Data from the treatment arm of the randomized controlled trial of PMHC were used (n = 459). The main outcomes were (reliable) recovery rate and symptoms of depression (PHQ-9) and anxiety (GAD-7). Primary outcome data at 24- and 36-months follow-up were available for 47% and 39% of participants, respectively. Secondary outcomes were work participation, functional status, health-related quality of life, and positive mental well-being. Sensitivity analyses with regard to missing data assumptions were conducted for the primary continuous outcomes.

RESULTS

Improvements were maintained at 24- and 36-month follow-up for symptoms of depression and anxiety, (reliable) recovery rate, and health-related quality of life. Small linear improvements since 6-month follow-up were observed for work participation, functional status, and positive mental well-being. Sensitivity analyses did not substantially alter the findings for symptoms of depression and anxiety mentioned above.

CONCLUSIONS

Our findings support the long-term effectiveness of PMHC, but results should be interpreted with caution due to lacking follow-up data at 24- and 36-month in the control group, and substantial attrition.

Utilization of passive visual perception task indetecting patients with major depressive disorder for active health

Depression is a common emotional and mental disease. At present, doctors' diagnosis mainly depends on the existing evaluation scales and their accumulated experience, lack of objective electrophysiological quantitative evaluation indicators. This study explores the difference in event-related potential (ERP) between patients with depression and healthy controls under the stimulation of multi-dimensional tasks, extracts the characteristic data, and uses a t-test for statistical analysis to provide an objective evaluation index for the clinical diagnosis of depression. Ninety-nine patients in the major depression group (MDD) and thirty patients in the healthy control group (HC) were used to compare the responses to positive, negative, and neutral stimulation, the results showed that there were significant differences between the left and right occipital lobes and one frontal lobe, and the frontal lobe showed lateralization; There were significant differences between the depression group and the healthy control group under multi-dimensional stimulation (P < 0.01), and the depression patients were significantly lower than the healthy patients. The results showed that emotional information was processed differently in patients with depression in the early stages of visual face processing. Therefore, EEG indices could be used as an objective index for the early detection of depression. Moreover, according to the instructions before the test, the subject is only asked to recognize visual pictures instead report emotional feelings. Stigma about psychiatric disorders could thus be reduced in this way. The explorations above facilitate designing more accurate and implicit active mental health techniques.

Antidepressant medication use by patients accessing a national digital mental health service

BACKGROUND

Digital mental health services (DMHSs) provide psychological treatments via the internet or phone and are increasingly being offered as part of routine care. This study describes antidepressant (AD) medication use and treatment outcomes in a large sample of routine care patients accessing a DMHS.

METHODS

Patients completing an assessment with an Australia-wide DMHS (MindSpot Clinic) from 1st January to 31st December 2020 (n = 17,409) were asked about psychotropic medication use. Demographic characteristics and treatment outcomes on the PHQ-9 (depression), GAD-7 (anxiety), and K-10+ (general distress) were compared for patients taking an AD versus no AD. Treatment outcomes were also analyzed for a subgroup of patients reporting recent commencement of AD medication.

RESULTS

Almost one quarter of patients (4141/17409; 23.8%) reported taking an AD, mainly selective serotonin reuptake inhibitors (SSRIs). Patients taking ADs had more severe symptoms however effect sizes were large (Cohen's d's > 1.0). Patients recently commencing ADs had the highest baseline symptoms but showed greater symptom improvement at post-treatment and 3-month follow-up.

LIMITATIONS

Treatment trajectory was measured weekly using standardized scales that are sensitive to change, however they did not allow formal clinical diagnoses of depression and were subject to the effects of missing data. The observational design did not control for spontaneous recovery or for comorbid conditions that might influence recovery.

CONCLUSIONS

Despite these limitations, online treatment provided by a DMHS as part of routine care is acceptable and effective for patients reporting concurrent AD medication use.

Effects of mindfulness-based intervention programs on sleep among people with common mental disorders: A systematic review and meta-analysis

BACKGROUND

Sleep problems are particularly prevalent in people with depression or anxiety disorder. Although mindfulness has been suggested as an important component in alleviating insomnia, no comprehensive review and meta-analysis has been conducted to evaluate the effects of different mindfulness-based intervention (MBI) programs on sleep among people with depression or anxiety disorder.

AIM

To compare the effects of different MBI programs on sleep among people with depression or anxiety disorder.

METHODS

Related publications in Embase, Medline, PubMed and PsycINFO databases were systematically searched from January 2010 to June 2020 for randomised controlled trials. Data were synthesized using a random-effects or a fixed-effects model to analyse the effects of various MBI programs on sleep problems among people with depression or anxiety disorder. The fixed-effects model was used when heterogeneity was negligible, and the random-effects model was used when heterogeneity was significant to calculate the standardised mean differences (SMDs) and 95% confidence intervals (CIs).

RESULTS

We identified 397 articles, of which 10 randomised controlled trials, involving a total of 541 participants, were included in the meta-analysis. Studies of internet mindfulness meditation intervention (IMMI), mindfulness meditation (MM), mindfulness-based cognitive therapy (MBCT), mindfulness-based stress reduction (MBSR) and mindfulness-based touch therapy (MBTT) met the inclusion criteria. The greatest effect sizes are reported in favour of MBTT, with SMDs of -1.138 (95%CI: -1.937 to -0.340; P = 0.005), followed by -1.003 (95%CI: -1.645 to -0.360; P = 0.002) for MBCT. SMDs of -0.618 (95%CI: -0.980 to -0.257; P = 0.001) and -0.551 (95%CI: -0.842 to -0.260; P < 0.0001) were reported for IMMI and MBSR in the pooling trials, respectively. Significant effects on sleep problem improvement are shown in all reviewed MBI programs, except MM, for which the effect size was shown to be non-significant.

CONCLUSION

All MBI programs (MBTT, MBCT, IMMI and MBSR), except MM, are effective options to improve sleep problems among people with depression or anxiety disorder.

Benefits of Digital Mental Health Care Interventions for Correctional Workers and Other Public Safety Personnel: A Narrative Review

Chronic exposure to stressors and potentially psychologically traumatic events contributes to the high prevalence of mental health disorders in correctional workers (CWs) and other public safety personnel (PSP). Digital mental health interventions are an accessible and scalable method of improving and maintaining the mental health of this population. The current review explores the benefits of digital mental health interventions for PSP-with a focus on CWs-and how these innovations can address the limitations in in-person mental health care. A systematic literature search of five databases (Medline, PsycInfo, Embase, CINAHL, Google Scholar) was conducted until March 2022. The search yielded 16 publications that focused on digital mental health interventions or care available to CWs and other PSP. The benefits of digital innovations were summarized into five categories which discussed (1) their ability to enhance accessibility and reduce stigma; (2) the provision of evidence-based and structured psychotherapy programs; (3) variability in the degree of therapist engagement; (4) the integration of proactive interventions; and (5) enhancing engagement by acknowledging unique experiences and interpersonal relationships. Although digital mental health technologies for CWs are still in their infancy, there is strong evidence to support their effectiveness in ameliorating symptoms of mental distress. Future research should consider how ethnicity, gender, culture, sexual orientation, and socioeconomic status can be integrated into these therapies and how the interplay between different stakeholders and organizations can impact the effectiveness of online therapies and programs.

Effectiveness of Videoconference-Delivered Cognitive Behavioral Therapy for Adults With Psychiatric Disorders: Systematic and Meta-Analytic Review

Background

Cognitive behavioral therapy (CBT) is the gold standard of psychotherapy for psychiatric disorders. However, the format of delivering CBT in person limits access to the intervention. The advancements in information and communication technology, especially the internet, present an opportunity for cognitive behavioral therapists to service patients or clients in remote areas through videoconferencing. Although many randomized controlled trials of videoconference-delivered cognitive behavioral therapy (VCBT) have already been conducted, the overall estimated effect size of VCBT for psychiatric disorders has not been examined by systematic reviews and meta-analyses.

Objective

This study attempts to evaluate the effectiveness of VCBT for psychiatric disorders through a systematic and meta-analytic review.

Methods

A systematic review and meta-analysis of studies in which VCBT was directly compared to control groups (such as treatment as usual, attention control, wait-list control, and other minimal supports) was carried out. To identify previous studies that meet our study objective, 2 independent reviewers undertook a systematic search through seven databases: MEDLINE (via PubMed), Web of Science, Science Direct, PsycINFO, CINAHL, LILACS, and SciELO. Other databases (ClinicalTrials.gov and Cochrane Central Resister of Controlled Trials) were also checked. All studies included in the review were assessed using the quality criteria of the Cochrane Collaboration. Statistical analysis was performed by using Cochrane Review Manager (RevMan, version 5.4.0). Standardized mean difference was used in major meta-analyses where a P value of .05 or less was the threshold for statistical significance. A heterogeneity test and the chi-square test were performed to assess the presence and extent of statistical heterogeneity with significance set at P<.10. Funnel plots were visually inspected to assess the risk of bias. Subgroup analyses were conducted for each disorder to estimate intervention effects.

Results

The systematic search resulted in 16 studies (total N=1745) that met the criteria for this study and were included in the review. There were 10 studies on depressive symptoms, 3 on chronic pain, 1 on generalized anxiety disorder, 1 on obsessive-compulsive disorder, and 1 on hypochondriasis. The quality and risk of bias was also assessed. Results showed a pooled effect size (Hedge g) post treatment of −0.49 (95% CI –0.68 to –0.29), indicating that VCBT is effective for clients with psychiatric disorders. Study quality did not affect outcomes.

Conclusions

While the overall results indicate the effectiveness of VCBT, there are still only a limited number of studies on specific psychiatric and somatic conditions. Therefore, more randomized controlled trials are needed to establish the effectiveness of VCBT for different disorders.

Cognitive behavioral therapy for depressive disorders: Outcomes from a multi-state, multi-site primary care practice

BACKGROUND

Individuals with depressive disorders often present to and seek treatment in primary care. Integrated behavioral health services within this setting can improve access to evidence-based cognitive behavioral therapy (CBT). However, limited information exists on the effectiveness of CBT for depression in primary care.

METHODS

Of the 1,302 participants with a primary depressive disorder referred by their primary care provider, 435 endorsed moderate to severe depression at baseline and engaged in at least one CBT session. A psychotherapy tracking database was used to collect relevant data, which included demographics, clinical characteristics, treatment outcomes, and CBT intervention use.

RESULTS

Participants with moderate to severe depression who participated in CBT reported a significant decrease in depression and anxiety symptoms at the end of treatment (p ≤ .001, d = 0.52-0.78). Rates of reliable change, response, and remission and types of CBT interventions used differed between major and persistent depressive disorders.

LIMITATIONS

Multiple limitations must be noted, which are related to the naturalistic study design, inclusion and exclusion criteria, sample operationalization, symptomatic measurement, time-limited and focused assessment, data collection strategies, and psychological services. Together, these temper the conclusions that can be drawn.

CONCLUSION

Significant reductions in depression and anxiety symptoms were reported by participants with depressive disorders who engaged in short-term CBT within primary care. This study indicates that CBT can be implemented within primary care and suggests that primary care patients with depression can benefit from integrated psychological services, supporting population-based models of care.

Service users experience of psychological interventions in primary care settings: A qualitative meta-synthesis

Primary care mental health services play a crucial role in public mental health by providing local and accessible psychological interventions that meet individuals' needs. Despite growing research investigating service users' perspectives of psychological interventions, a qualitative systematic review in this context is not available. The present meta-synthesis collates the existing articles and gives a thematic synthesis of qualitative studies on service users' experience of psychological interventions in primary care. Multiple databases (CINAHL, EMBASE, PsychINFO, MEDLINE, and Cochrane Library) were searched for published qualitative studies of service users' experiences of psychological interventions delivered in primary care. Articles were included if they met inclusion criteria. Study quality was assessed using the Critical Appraisal Skills Programme tool. All types of psychological interventions were considered across model and delivery format (e.g., face-to-face, computerised programmes, and group). NVIVO was used to code the dataset and themes were extracted following thematic synthesis. Twenty-two studies were included. Four analytical themes and 10 subthemes emerged. The identified themes were as follows: (1) 'Access and Acceptability: facilitators and barriers', (2) 'Structural aspects'; (3) 'Therapeutic process' and (4) 'Outcomes'. A model of interrelationships between themes is proposed. Findings suggest several 'essential ingredients' across psychological interventions and modalities. The crucial role of relational factors, the importance of assessing service users' perceptions of treatment features (e.g., remote delivery) and of tailoring the intervention to their needs were emphasised. Results also suggest involving service users more in discussions and decisions about psychological interventions offered might enhance access, acceptability, and engagement. Recommendations for practice and research are provided.

Inequities in the delivery of mental health care: a grounded theory study of the policy context of primary care

BACKGROUND

Strengthening capacity for mental health in primary care improves health outcomes by providing timely access to coordinated and integrated mental health care. The successful integration of mental health in primary care is highly dependent on the foundation of the surrounding policy context. In Ontario, Canada, policy reforms in the early 2000's led to the implementation of a new interprofessional team-model of primary care called Family Health Teams. It is unclear the extent to which the policy context in Ontario influenced the integration of mental health care in Family Health Teams emerging from this period of policy reform. The research question guiding this study was: what were key features of Ontario's policy context that influenced FHTs capacity to provide mental health services for mood and anxiety disorders?

METHODS

A qualitative study informed by constructivist grounded theory. Individual interviews were conducted with executive directors, family physicians, nurse practitioners, nurses, and the range of professionals who provide mental health services in interprofessional primary care teams; community mental health providers; and provincial policy and decision makers. We used an inductive approach to data analysis. The electronic data management programme NVivo11 helped organise the data analysis process.

RESULTS

We conducted 96 interviews with 82 participants. With respect to the contextual factors considered to be important features of Ontario's policy context that influenced primary care teams' capacity to provide mental health services, we identified four key themes: i) lack of strategic direction for mental health, ii) inadequate resourcing for mental health care, iii) rivalry and envy, and, iv) variations across primary care models.

CONCLUSIONS

As the first point of contact for individuals experiencing mental health difficulties, primary care plays an important role in addressing population mental health care needs. In Ontario, the successful integration of mental health in primary care has been hindered by the lack of strategic direction, and inconsistent resourcing for mental health care. Achieving health equity may be stunted by the structural variations for mental health care across Family Health Teams and across primary care models in Ontario.

Psychologic Treatment of Depression Compared With Pharmacotherapy and Combined Treatment in Primary Care: A Network Meta-Analysis

PURPOSE

Most patients with depression are treated by general practitioners, and most of those patients prefer psychotherapy over pharmacotherapy. No network meta-analyses have examined the effects of psychotherapy compared with pharmacotherapy, combined treatment, care as usual, and other control conditions among patients in primary care.

METHODS

We conducted systematic searches of bibliographic databases to identify randomized trials comparing psychotherapy with pharmacotherapy, combined treatment, care as usual, waitlist, and pill placebo. The main outcome was treatment response (50% improvement of depressive symptoms from baseline to end point).

RESULTS

A total of 58 studies with 9,301 patients were included. Both psychotherapy and pharmacotherapy were significantly more effective than care as usual (relative risk [RR] for response = 1.60; 95% CI, 1.40-1.83 and RR = 1.65; 95% CI, 1.35-2.03, respectively) and waitlist (RR = 2.35; 95% CI, 1.57-3.51 and RR = 2.43; 95% CI, 1.57-3.74, respectively) control groups. We found no significant differences between psychotherapy and pharmacotherapy (RR = 1.03; 95% CI, 0.88-1.22). The effects were significantly greater for combined treatment compared with psychotherapy alone (RR = 1.35; 95% CI, 1.00-1.81). The difference between combined treatment and pharmacotherapy became significant when limited to studies with low risk of bias and studies limited to cognitive behavior therapy.

CONCLUSIONS

Psychotherapy is likely effective for the treatment of depression when compared with care as usual or waitlist, with effects comparable to those of pharmacotherapy. Combined treatment might be better than either psychotherapy or pharmacotherapy alone.

Depression in multiple sclerosis: Is one approach for its management enough?

BACKGROUND

Major depression disorder (MDD) and severe depression symptoms are highly prevalent in multiple sclerosis (MS). Depression can worsen symptoms of MS and is associated with significantly reduced quality of life and increased risk of suicide. Currently, there is no gold-standard, single treatment available for depression in MS. Pharmacotherapy, cognitive behavior therapy (CBT), and exercise training individually are moderately, yet incompletely, efficacious for managing depression in the general population and MS.

PURPOSE

This review provides an overview of evidence from meta-analyses and systematic reviews for current treatments of depression in persons with MS. This review further develops the rationale for using a combinatory treatment approach in persons with MS.

METHODS

We performed a narrative review of meta-analyses and systematic reviews regarding the current state of evidence for the three most common treatments of depression in persons with MS (i.e., antidepressant medication, cognitive-behavior therapy, and exercise training). We provide a concise assessment of the overall effect of these treatments on depression in the general population and then persons with MS. We further note short-comings of research on these treatments for depression.

CONCLUSION

There is no single, gold-standard treatment for depression in MS, and we proposed that combinatory treatments should be considered for the management of depression in MS. However, there is a paucity of evidence for the use of combinatory therapy on depression and its outcomes in persons with MS, and this supports direct examination of the feasibility and efficacy of such combinatory approaches for MDD in MS.

Integrating Behavioral Health and Primary Care (IBH-PC) to improve patient-centered outcomes in adults with multiple chronic medical and behavioral health conditions: study protocol for a pragmatic cluster-randomized control trial

BACKGROUND

Chronic diseases that drive morbidity, mortality, and health care costs are largely influenced by human behavior. Behavioral health conditions such as anxiety, depression, and substance use disorders can often be effectively managed. The majority of patients in need of behavioral health care are seen in primary care, which often has difficulty responding. Some primary care practices are providing integrated behavioral health care (IBH), where primary care and behavioral health providers work together, in one location, using a team-based approach. Research suggests there may be an association between IBH and improved patient outcomes. However, it is often difficult for practices to achieve high levels of integration. The Integrating Behavioral Health and Primary Care study responds to this need by testing the effectiveness of a comprehensive practice-level intervention designed to improve outcomes in patients with multiple chronic medical and behavioral health conditions by increasing the practice's degree of behavioral health integration.

METHODS

Forty-five primary care practices, with existing onsite behavioral health care, will be recruited for this study. Forty-three practices will be randomized to the intervention or usual care arm, while 2 practices will be considered "Vanguard" (pilot) practices for developing the intervention. The intervention is a 24-month supported practice change process including an online curriculum, a practice redesign and implementation workbook, remote quality improvement coaching services, and an online learning community. Each practice's degree of behavioral health integration will be measured using the Practice Integration Profile. Approximately 75 patients with both chronic medical and behavioral health conditions from each practice will be asked to complete a series of surveys to measure patient-centered outcomes. Change in practice degree of behavioral health integration and patient-centered outcomes will be compared between the two groups. Practice-level case studies will be conducted to better understand the contextual factors influencing integration.

DISCUSSION

As primary care practices are encouraged to provide IBH services, evidence-based interventions to increase practice integration will be needed. This study will demonstrate the effectiveness of one such intervention in a pragmatic, real-world setting.

Cognitive-behavioural therapy for a variety of conditions: an overview of systematic reviews and panoramic meta-analysis

BACKGROUND

Cognitive-behavioural therapy aims to increase quality of life by changing cognitive and behavioural factors that maintain problematic symptoms. A previous overview of cognitive-behavioural therapy systematic reviews suggested that cognitive-behavioural therapy was effective for many conditions. However, few of the included reviews synthesised randomised controlled trials.

OBJECTIVES

This project was undertaken to map the quality and gaps in the cognitive-behavioural therapy systematic review of randomised controlled trial evidence base. Panoramic meta-analyses were also conducted to identify any across-condition general effects of cognitive-behavioural therapy.

DATA SOURCES

The overview was designed with cognitive-behavioural therapy patients, clinicians and researchers. The Cochrane Library, MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Child Development & Adolescent Studies, Database of Abstracts of Reviews of Effects and OpenGrey databases were searched from 1992 to January 2019.

REVIEW METHODS

Study inclusion criteria were as follows: (1) fulfil the Centre for Reviews and Dissemination criteria; (2) intervention reported as cognitive-behavioural therapy or including one cognitive and one behavioural element; (3) include a synthesis of cognitive-behavioural therapy trials; (4) include either health-related quality of life, depression, anxiety or pain outcome; and (5) available in English. Review quality was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2. Reviews were quality assessed and data were extracted in duplicate by two independent researchers, and then mapped according to condition, population, context and quality. The effects from high-quality reviews were pooled within condition groups, using a random-effect panoramic meta-analysis. If the across-condition heterogeneity was I2 < 75%, we pooled across conditions. Subgroup analyses were conducted for age, delivery format, comparator type and length of follow-up, and a sensitivity analysis was performed for quality.

RESULTS

A total of 494 reviews were mapped, representing 68% (27/40) of the categories of the International Classification of Diseases, Eleventh Revision, Mortality and Morbidity Statistics. Most reviews (71%, 351/494) were of lower quality. Research on older adults, using cognitive-behavioural therapy preventatively, ethnic minorities and people living outside Europe, North America or Australasia was limited. Out of 494 reviews, 71 were included in the primary panoramic meta-analyses. A modest effect was found in favour of cognitive-behavioural therapy for health-related quality of life (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.05 to 0.50, I2 = 32%), anxiety (standardised mean difference 0.30, 95% confidence interval 0.18 to 0.43, prediction interval -0.28 to 0.88, I2 = 62%) and pain (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.28 to 0.74, I2 = 64%) outcomes. All condition, subgroup and sensitivity effect estimates remained consistent with the general effect. A statistically significant interaction effect was evident between the active and non-active comparator groups for the health-related quality-of-life outcome. A general effect for depression outcomes was not produced as a result of considerable heterogeneity across reviews and conditions.

LIMITATIONS

Data extraction and analysis were conducted at the review level, rather than returning to the individual trial data. This meant that the risk of bias of the individual trials could not be accounted for, but only the quality of the systematic reviews that synthesised them.

CONCLUSION

Owing to the consistency and homogeneity of the highest-quality evidence, it is proposed that cognitive-behavioural therapy can produce a modest general, across-condition benefit in health-related quality-of-life, anxiety and pain outcomes.

FUTURE WORK

Future research should focus on how the modest effect sizes seen with cognitive-behavioural therapy can be increased, for example identifying alternative delivery formats to increase adherence and reduce dropout, and pursuing novel methods to assess intervention fidelity and quality.

Cultural adaptations of cognitive behavioural therapy for Latin American patients: unexpected findings from a systematic review

The current literature extensively recommends making cultural adaptations to psychological therapies, in order to address the differences in values, beliefs and attitudes that patients from different ethnic groups might hold. Although this approach has shown positive outcomes in some settings, it is not well established yet whether such adaptations are needed for all therapies and in all cultures. Therefore, the main aim of this study was to systematically review the literature regarding culturally adapted and ‘conventional’ cognitive behavioural therapy (CBT) for Latin American patients, within Latin American and non-Latin American countries. Sixty empirical studies regarding the effectiveness of culturally adapted and conventional CBT were included in this review. The included studies were carried out in Latin American and non-Latin American countries. The information from all studies was synthesized and assessed, including intervention effect sizes, patient retention rates, methodological quality of the papers, and the type of cultural adaptation made to the therapy. There were no differences between the sets of studies in terms of effectiveness, retention rates, methodological quality, or proportion of statistically significant interventions. Most of the cultural adaptations were peripheral or unspecified. The evidence to date indicates that both conventional and culturally adapted CBT offer the same benefits for Latin American patients in terms of effectiveness and retention rates. Rather than focusing on cultural adaptations, clinicians are encouraged to improve the way they deliver CBT through training and supervision.

A randomized controlled trial on the comparative effectiveness of mindfulness-based cognitive therapy and health qigong-based cognitive therapy among Chinese people with depression and anxiety disorders

BACKGROUND

The goal of this study was to investigate treatment outcome and related intervention processes of mindfulness-based cognitive therapy versus health qigong-based cognitive therapy versus waitlist control among individuals with mood disorders.

METHODS

A total of 187 individuals with mood disorders were randomized and allocated into mindfulness-based cognitive therapy, health qigong-based cognitive therapy, or waitlist control groups. All participants were assessed at three time points with regard to depressive and anxiety symptoms, physical and mental health status, perceived stress, sleep quality, and self-efficacy. Linear mixed models analysis was used to test the individual growth model by studying the longitudinal data.

RESULTS

Mindfulness-based cognitive therapy and health qigong-based cognitive therapy both produced greater improvements on all outcome measures as compared with waitlist control. Relatively, more reductions of mood symptoms were observed in the health qigong-based cognitive therapy group as compared with the mindfulness-based cognitive therapy group. Health qigong-based cognitive therapy is more conducive to physical health status whereas mindfulness-based cognitive therapy has more favorable mental health outcomes. Individual growth curve models indicated that alterations in perceived stress was the common predictor of mood changes in both intervention groups.

CONCLUSIONS

The predominant emphasis on physical health in health qigong-based cognitive therapy makes it more acceptable and effective than mindfulness-based cognitive therapy as applied in Chinese individuals with mood disorders. The influence of Chinese culture is discussed.

Long-term outcomes of Prompt Mental Health Care: A randomized controlled trial

Prompt Mental Health Care (PMHC, Norwegian adaptation of Improving Access to Psychological Therapies) is found successful in alleviating symptoms of anxiety and depression. Here, we investigate whether improvement is maintained over time. A randomized controlled trial was conducted in two PMHC sites from November 2015 to August 2017, randomly assigning 681 adults with anxiety and/or mild to moderate depression (70:30 ratio: PMHC n = 463, TAU n = 218). Main outcomes were recovery rates and changes in symptoms of depression and anxiety from baseline to 12 months. Secondary outcomes were functional status, health-related quality of life, mental wellbeing and work participation. At 12 months after baseline the reliable recovery rate was 59.4% in PMHC and 36.6% in TAU, giving a between-group effect size of 0.51 (95%CI: 0.26, 0.77, p < 0.001). Differences in symptom change gave between-group effect sizes of -0.67 (95%CI: -0.99, -0.36, p < 0.001) for depression and -0.58 (95%CI: -0.91, -0.26, p < 0.001) for anxiety. PMHC was also at 12 months found more effective in improving functional status, health-related quality of life and mental wellbeing, but not work participation. In sum, substantial treatment effects of PMHC remain at 12 months follow-up, although results should be interpreted with caution due to risk of attrition bias.

Psychological interventions for posttraumatic stress disorder involving primary care physicians: systematic review and Meta-analysis of randomized controlled trials

Background

Evidence-based psychological interventions for posttraumatic stress disorder (PTSD) are available in specialized settings, but adequate care in primary care is often lacking.

The aim of this systematic review was to determine the effectiveness of psychological interventions for PTSD involving primary care physicians (PCPs) and to characterize these interventions as well as their providers.

Method

A systematic review and meta-analyses of randomized controlled trials (RCTs). Primary outcome were symptoms of PTSD.

Results

Four RCTs with a total of 774 patients suffering from PTSD symptoms were included, all applying cognitive behavioural based interventions. Three studies with psychological interventions being conducted by case managers were pooled in a meta-analysis. Interventions were not effective in the short term (0–6 months; SMD, − 0.1; 95% CI, − 0.24-0.04; I² = 0%). Only two studies contributed to the meta-analysis for long term (12–18 months) outcomes yielding a small effect (SMD, − 0.23; 95% CI, − 0.38- -0.08; I² = 0%).

Conclusions

Psychological interventions for PTSD in primary care settings may be effective in the long term but number and quality of included studies was limited so the results should be interpreted with caution.

Efficacy of a Guided Web-Based Self-Management Intervention for Depression or Dysthymia: Randomized Controlled Trial With a 12-Month Follow-Up Using an Active Control Condition

BACKGROUND

An increasing number of studies suggest that web-based interventions for patients with depression can reduce their symptoms and are expected to fill currently existing treatment gaps. However, evidence for their efficacy has mainly been derived from comparisons with wait-list or treatment as usual controls. In particular, designs using wait-list controls are unlikely to induce hope and may even have nocebo effects, making it difficult to draw conclusions about the intervention's efficacy. Studies using active controls are rare and have not yielded conclusive results.

OBJECTIVE

The main objective of this study is to assess the acute and long-term antidepressant efficacy of a 6-week, guided, web-based self-management intervention building on the principles of cognitive behavioral therapy (iFightDepression tool) for patients with depression compared with web-based progressive muscle relaxation as an active control condition.

METHODS

A total of 348 patients with mild-to-moderate depressive symptoms or dysthymia (according to the Mini International Neuropsychiatric Interview) were recruited online and randomly assigned to 1 of the 2 intervention arms. Acute antidepressant effects after 6 weeks and long-term effects at 3-, 6-, and 12-month follow-up were studied using the Inventory of Depressive Symptomatology-self-rating as a primary outcome parameter and change in quality of life (Short Form 12) and user satisfaction (client satisfaction questionnaire) as secondary outcome parameters. Treatment effects were assessed using mixed model analyses.

RESULTS

Over the entire observation period, a greater reduction in symptoms of depression (P=.01) and a greater improvement of life quality (P<.001) was found in the intervention group compared with the active control group. Separate tests for each time point revealed significant effects on depressive symptoms at the 3-month follow-up (d=0.281; 95% CI 0.069 to 0.493), but not after 6 weeks (main outcome:d=0.192; 95% CI -0.020 to 0.404) and 6 and 12 months. The intervention was significantly superior to the control condition with respect to user satisfaction (25.31 vs 21.97; t₂₅₉=5.804; P<.01).

CONCLUSIONS

The fact that antidepressant effects have been found for a guided self-management tool in comparison with an active control strengthens the evidence base for the efficacy of web-based interventions. The antidepressant effect became most prominent at the 3-month follow-up. After 6 weeks of intervention, significant positive effects were observed on life quality but not on depressive symptoms. Although the effect size of such web-based interventions on symptoms of depression might be smaller than that suggested by earlier studies using wait-list control conditions, they can be a cost-effective addition to antidepressants and face-to-face psychotherapy.

Trends in psychiatric diagnoses, medications and psychological therapies in a large Swedish region: a population-based study

BACKGROUND

Health services utilization for mental health disorders is reported to increase sharply in many countries. The aim of this study was to report trends in all aspects of mental health care utilization in a total population sample.

METHODS

Repeated cross-sectional register study of the Stockholm Region (VAL) including both primary and secondary care. Trends in the proportion of adults in the total population of Stockholm Region with a recorded ICD-10 psychiatric diagnosis or psychological therapy during 2007-2017 as well as claims of psychiatric medication from 2011 were calculated.

RESULTS

The proportion of adults utilizing any mental health care increased from 13.2% in 2011 to 16.1% in 2017. In 2017, 49.3% were treated in primary care, 32.2% in secondary care and 18.5% were jointly managed. The increase was most pronounced in younger adults. Women were more likely to receive mental health care than men in all ages. Medication decreased from 71.0 to 67.7%, while psychological therapy increased from 33.1 to 37.6%. The use of psychiatric medication increased with age while psychological therapy decreased. All time trends were statistically significant (p < .0001).

CONCLUSION

Care for mental health disorders has been increasing mainly in primary care and was delivered to one in seven adult individuals in 2017. Interventions are needed to address the growing burden of mental health disorders while avoiding overtreatment.

Insomnia, Anxiety and Depression in Adult Cochlear Implant Users With Tinnitus

OBJECTIVE

Determine the prevalence of clinical insomnia and its associations with anxiety, depression, and tinnitus in adult cochlear implant (CI) users.

DESIGN

Self-reported information on tinnitus, sleep, and demographic variables was collected from adult CI users (n = 127). Tinnitus presence, its persistence, related emotional distress, and difficulties with sleep were assessed using questions from the UK Biobank study (www.ukbiobank.ac.uk). Tinnitus-related handicap was assessed using the Tinnitus Handicap Inventory. Clinical insomnia symptoms were characterized using the Insomnia Severity Index (ISI), and clinical anxiety and depression symptoms using the Hospital Anxiety and Depression Scale (HADS). Regression models were used to compare the data from CI users with and without tinnitus, and to test the associations between clinical insomnia, anxiety, depression and tinnitus handicap.

RESULTS

About a half (53%) of CI users reported tinnitus, of whom 54% described it as persistent, 41% as emotionally distressing and 73% reported having difficulties with sleep based on the UK Biobank questions. The ISI suggested that clinically abnormal insomnia symptoms were more likely to occur with tinnitus (odds ratio [OR] = 2.60, 95% confidence interval 1.04 to 6.45; p = 0.040) and were found in 41% of CI users with tinnitus. Post-hoc exploratory analyses on the ISI suggested that CI users with tinnitus experienced greater levels of difficulty falling asleep, lower satisfaction with sleep patterns, greater interference of sleep problems with daily activities, and a greater impact on their quality of life. The HADS scores suggested that those with tinnitus were also more likely to have clinically abnormal anxiety (42%; OR = 3.50, 95% confidence interval 1.49 to 8.22; p = 0.004) and depression symptoms (14%; OR = 6.18, 95% confidence interval 1.17 to 32.82; p = 0.032). The clinical insomnia observed in CI users with tinnitus was associated with tinnitus handicap (p = 0.028), and the levels of clinical anxiety (p = 0.012) and depression (p < 0.001).

CONCLUSIONS

Clinically abnormal insomnia symptoms are prevalent, potentially affecting over 40% of CI users with tinnitus. The associations between clinical insomnia, anxiety, and depression symptoms, and tinnitus-related handicap suggest that all of these symptoms should be considered when assessing the tinnitus-related burden and its impact on the quality of life after cochlear implantation. The present findings also have potential implications for the clinical management of CI recipients with tinnitus, in whom it may be advisable to monitor sleep problems so that they can be addressed where appropriate. Further research is needed to investigate the mechanisms and causal links behind insomnia and tinnitus-related symptoms in this population. Future studies should also investigate the feasibility and effectiveness of night time use of CIs to alleviate tinnitus-related insomnia. The potential impact of insomnia on the quality of life of CI users with tinnitus highlights the importance of including sleep measures in future evaluations of the effectiveness of cochlear implantation for the alleviation of tinnitus.

Effectiveness of Prompt Mental Health Care, the Norwegian Version of Improving Access to Psychological Therapies: A Randomized Controlled Trial

BACKGROUND

The innovative treatment model Improving Access to Psychological Therapies (IAPT) and its Norwegian adaptation, Prompt Mental Health Care (PMHC), have been evaluated by cohort studies only. Albeit yielding promising results, the extent to which these are attributable to the treatment thus remains unsettled.

OBJECTIVE

To investigate the effectiveness of the PMHC treatment compared to treatment as usual (TAU) at 6-month follow-up.

METHODS

A randomized controlled trial with parallel assignment was performed in two PMHC sites (Sandnes and Kristiansand) and enrolled clients between November 9, 2015 and August 31, 2017. Participants were 681 adults (aged ≥18 years) considered for admission to PMHC due to anxiety and/or mild to moderate depression (Patient Health Questionnaire [PHQ-9]/Generalized Anxiety Disorder scale [GAD-7] scores above cutoff). These were randomly assigned (70:30 ratio; n = 463 to PMHC, n = 218 to TAU) with simple randomization within each site with no further constraints. The main outcomes were recovery rates and changes in symptoms of depression (PHQ-9) and anxiety (GAD-7) between baseline and follow-up. Primary outcome data were available for 73/67% in PMHC/TAU. Sensitivity analyses based on observed patterns of missingness were also conducted. Secondary outcomes were work participation, functional status, health-related quality of life, and mental well-being.

RESULTS

A reliable recovery rate of 58.5% was observed in the PMHC group and of 31.9% in the TAU group, equaling a between-group effect size of 0.61 (95% CI 0.37 to 0.85, p < 0.001). The differences in degree of improvement between PMHC and TAU yielded an effect size of -0.88 (95% CI -1.23 to -0.43, p < 0.001) for PHQ-9 and -0.60 (95% CI -0.90 to -0.30, p < 0.001) for GAD-7 in favor of PMHC. All sensitivity analyses pointed in the same direction, with small variations in point estimates. Findings were slightly more robust for depressive than anxiety symptoms. PMHC was also more effective than TAU in improving all secondary outcomes, except for work participation (z = 0.415, p = 0.69).

CONCLUSIONS

The PMHC treatment was substantially more effective than TAU in alleviating the burden of anxiety and depression. This adaptation of IAPT is considered a viable supplement to existing health services to increase access to effective treatment for adults who suffer from anxiety and mild to moderate depression. A potential effect on work participation needs further examination.

The Role of the Patient-Centered Medical Home in Treating Depression

PURPOSE OF REVIEW

This review discusses the role of the patient-centered medical home (PCMH) in treating depression, focusing on findings from primary care-based studies and their implications for the PCMH.

RECENT FINDINGS

Pharmacotherapy, psychotherapy, and collaborative care are evidence-based treatments for depression that can be delivered in primary care and extended to diverse populations. Recent research aligns with the core components of the PCMH model. The core components of the PCMH are critical elements of depression treatment. Comprehensive care within the PCMH addresses medical and behavioral health concerns, including depression. Psychiatric and psychological care must be flexibly delivered so services remain accessible yet patient-centered. To ensure the quality and safety of treatment, depression symptoms must be consistently monitored. Coordination within and occasionally outside of the PCMH is needed to ensure patients receive the appropriate level of care. More research is needed to empirically evaluate depression treatment within the PCMH.

Psychological Treatment of Depression in Primary Care: Recent Developments

PURPOSE OF REVIEW

We give an overview of recent developments on psychological treatments of depression in primary care.

RECENT FINDINGS

In recent years, it has become clear that psychotherapies can effectively be delivered through e-health applications. Furthermore, several studies in low and middle income countries have shown that lay health counselors can effectively deliver psychological therapies. Behavioral activation, a relatively simple form of therapy, has been found to be as effective as cognitive behavior therapy. Treatment of subthreshold depression has been found to not only reduce depressive symptoms but also prevent the onset of major depression. In addition, therapies are effective in older adults, patients with general medical disorders and in perinatal depression. Psychological therapies are effective in the treatment of depression in primary care, have longer lasting effects than drugs, are preferred by the majority of patients, and can be applied flexibly with different formats and across different target groups.

Guidelines for the evaluation and treatment of perimenopausal depression: summary and recommendations

There is a new appreciation of the perimenopause - defined as the early and late menopause transition stages as well as the early postmenopause - as a window of vulnerability for the development of both depressive symptoms and major depressive episodes. However, clinical recommendations on how to identify, characterize and treat clinical depression are lacking. To address this gap, an expert panel was convened to systematically review the published literature and develop guidelines on the evaluation and management of perimenopausal depression. The areas addressed included: 1) epidemiology; 2) clinical presentation; 3) therapeutic effects of antidepressants; 4) effects of hormone therapy; and 5) efficacy of other therapies (eg, psychotherapy, exercise, and natural health products). Overall, evidence generally suggests that most midlife women who experience a major depressive episode during the perimenopause have experienced a prior episode of depression. Midlife depression presents with classic depressive symptoms commonly in combination with menopause symptoms (ie, vasomotor symptoms, sleep disturbance), and psychosocial challenges. Menopause symptoms complicate, co-occur, and overlap with the presentation of depression. Diagnosis involves identification of menopausal stage, assessment of co-occurring psychiatric and menopause symptoms, appreciation of the psychosocial factors common in midlife, differential diagnoses, and the use of validated screening instruments. Proven therapeutic options for depression (ie, antidepressants, psychotherapy) are the front-line treatments for perimenopausal depression. Although estrogen therapy is not approved to treat perimenopausal depression, there is evidence that it has antidepressant effects in perimenopausal women, particularly those with concomitant vasomotor symptoms. Data on estrogen plus progestin are sparse and inconclusive.

Cognitive behaviour therapy for depression in primary care: systematic review and meta-analysis

Depression is common in primary care, and most patients prefer psychological treatment over pharmacotherapy. Cognitive behaviour therapy (CBT) is an effective treatment, but there are gaps in current knowledge about CBT in the primary care context, especially with regard to long-term effects and the efficacy of specific delivery formats. This is an obstacle to the integration of primary care and specialist psychiatry. We conducted a systematic review and meta-analysis of randomised controlled trials of CBT for primary care patients with depression to investigate the effect of CBT for patients with depression in primary care. A total of 34 studies, with 2543 patients in CBT and 2815 patients in control conditions, were included. CBT was more effective than the control conditions [g = 0.22 (95% confidence interval (CI) 0.15-0.30)], and the effect was sustained at follow-up [g = 0.17 (95% CI 0.10-0.24)]. CBT also led to a higher response rate [odds ratio (OR) = 2.47 (95% CI 1.60-3.80)] and remission rate [OR = 1.56 (95% CI 1.15-2.14)] than the control conditions. Heterogeneity was moderate. The controlled effect of CBT was significant regardless of whether patients met diagnostic criteria for depression, scored above a validated cut-off for depression, or merely had depressive symptoms. CBT also had a controlled effect regardless of whether the treatment was delivered as individual therapy, group therapy or therapist-guided self-help. We conclude that CBT appears to be effective for patients with depression in primary care, and recommend that patients with mild to moderate depression be offered CBT in primary care.

Cognitive behavioral therapy for primary care depression and anxiety: a secondary meta-analytic review using robust variance estimation in meta-regression

Cognitive-behavioral therapy (CBT) is well supported for treating depressive and anxiety disorders. Trials of CBT for anxiety and depression in primary care have increased over the past decade, yet only one meta-analysis, published in 2015, examined this topic and the scope of that review is relatively narrow. This study conducted a systematic review and meta-analysis of primary care based CBT for depression and anxiety. A search of seven electronic databases, six professional websites, and reference lists from articles meeting inclusion criteria was conducted for studies published between 1900 and November 2018. Fifty-seven eligible studies (including 10,701 participants; 221 effect sizes) of randomized controlled trials were eligible and included for meta-analysis using robust variance estimation in meta-regression. Outcome indicators were depression and anxiety measures. An overall significant treatment effect, d = 0.400, 95% CI (0.235, 0.566), p < 0.001, of CBT for depression and anxiety disorders in primary care was identified. Subgroup analyses indicated significant treatment effect for: (1) depressive (d = 0.425, p < 0.001) and anxiety (d = 0.393, p < 0.01) outcomes, (2) studies conducted inside primary care (d = 0.412, p < 0.001), (3) studies using individual-based CBT (d = 0.412, p < 0.001), (4) studies without primary care physician involvement (d = 0.395, p < 0.001), and (5) studies using both tele-health (d = 0.563, p < 0.001) and in-person CBT (d = 0.363, p < 0.001). The percentage of White participants, treatment composition (CBT only versus CBT + other approaches), and treatment duration were significant moderators. Implications for clinical practice are discussed based on both moderator and subgroup analysis results.

Efficacy of an internet-based self-management intervention for depression or dysthymia - a study protocol of an RCT using an active control condition

BACKGROUND

The treatment of major depressive disorder, a highly prevalent disorder associated with pronounced burden, is a large challenge to healthcare systems worldwide. Internet based self-management interventions seem to be a cost effective way to complement the treatment of depressed patients, but the accumulating evidence is mainly based on the comparison to waitlist controls and treatment as usual, which might lead to an overestimation of effects. Furthermore, studies assessing long-term effects and possible negative outcomes are still rare.

METHODS/DESIGN

The proposed study evaluates the efficacy of the German version of the iFightDepression® tool in comparison to an active control condition. A total of 360 patients with mild to moderate depressive symptoms are included into a two-armed randomized controlled trial. They receive one of two six week interventions; either the iFightDepression® tool or progressive muscle relaxation serving as the control condition. Both intervention groups receive information material, weekly tasks via the internet and regular phone calls as part of the intervention. The primary outcome is change in depressive symptoms after the intervention period, as measured with the Inventory of Depressive Symptomatology. Satisfaction with the program, usability, changes in perceived quality of life, and possible negative effects are assessed as secondary outcomes.

DISCUSSION

This study represents the first randomized controlled trial on the iFightDepression® self-management tool in its German version, aiming at efficacy, but also at providing new insights into so far understudied aspects of E-mental health programs, namely the specificity of the treatment effect compared to an active control condition, it's continuity over a time course of 12 months, and possible negative effects of these internet based interventions.

TRIAL REGISTRATION

International trial-registration took place through the "international clinical trials registry platform" (WHO) with the secondary ID 080-15-09032015. German Clinical Trial Registration: DRKS00009323 (DRKS.de, registered on 25 February 2016).

Dissemination and Implementation of Cognitive Behavioral Therapy for Depression in the Kaiser Permanente Health Care System: Evaluation of Initial Training and Clinical Outcomes

Notwithstanding its empirical status and strong recommendation in clinical practice guidelines, cognitive behavioral therapy (CBT) continues to be delivered infrequently and with low fidelity on the clinical front lines. Recently, organized efforts and policies within the public sector to disseminate and implement CBT and other evidence-based psychotherapies have yielded encouraging results and provided optimism for bridging the research-to-practice-gap. Following from these efforts, the current article examines the initial impact and experience of the implementation of an individualized approach to CBT training and treatment within the Kaiser Permanente health care system. Initial training outcomes, including changes in general and specific competencies, were assessed using divergent assessment methods within the initial cohort of therapists undergoing training. Initial patient outcomes, including changes in depression and anxiety, were assessed among patients receiving treatment from therapists in training. Results revealed training in and implementation of CBT-D was associated with overall large improvements in therapist competencies and in clinically significant improvements in both depression and anxiety among patients. Findings from the initial phase of dissemination and implementation within a large private system provide support for, and extend recent findings related to, the feasibility and effectiveness of training in and implementation of CBT-D in a real-world context.

The effectiveness of four empirically supported psychotherapies for primary care depression and anxiety: A systematic review and meta-analysis

BACKGROUND

Depressive and anxiety disorders are highly prevalent and detrimental in primary care settings. However, there are gaps in the literature concerning effectiveness and generalizability of empirically supported interventions and treatment of both depression and anxiety in primary care settings. The aim of this review is to systematically assess and meta-analyze the effectiveness of brief empirically-supported psychotherapies for treating depression and/or anxiety in primary care.

METHODS

Seven electronic databases, five professional websites and manual search of reference lists were searched through April 2017 for randomized controlled trials (RCTs) of four psychotherapies treating primary care depression and anxiety: cognitive-behavior therapy (CBT), problem-solving therapy (PST), motivational interviewing (MI), and solution-focused brief therapy (SFBT).

RESULTS

From an initial pool of 1140 articles, 179 articles were eligible for full-text review and 65 articles were included for final analysis. Sixty-five articles containing 198 effect sizes reported an overall treatment effect size of d = 0.462, p < 0.001. Single-predictor meta-regression indicated that marital status, treatment modality (individual versus group), and treatment composition were significant moderators. Multiple-predictor meta-regression discovered treatment setting (inside versus outside primary care) significantly moderated treatment effect, b = -0.863, p = 0.039 after controlling for other intervention characteristics.

CONCLUSION

Treatment effects were found for CBT and PST, both for depressive and anxiety disorders. Interventions delivered outside primary care settings were more effective than those within, individual treatment had greater treatment effects compared to group treatment, and both technology-assisted and in-person treatments were found to be effective.
