Cross-sectional data related to depression and anxiety symptoms, sociodemographic characteristics, quality of life (QoL), and emotion-regulation processes were collected from 1,704 primary care patients. Correlation and analysis of variance (ANOVA) tests were conducted to identify those variables associated with both depression and anxiety. Participants were then divided into severe and nonsevere emotional symptoms, and binomial logistic regression was used to identify the variables that contributed the most to classify the severity. The final adjusted model included psychological QoL (p < .001, odds ratio [OR] = .426, 95% CI [.318, .569]), negative metacognitions (p < .001, OR = 1.083, 95% CI [1.045, 1.122]...

The Improving Access to Psychological Therapies (IAPT) project, launched in the United Kingdom in 2007, has become an international benchmark for the treatment of common mental disorders. In Spain, Psicofundación developed the PsicAP clinical trial, following the precedent set by the IAPT. Method: This study reviews and compares and contrasts the methods, results, and contributions of the IAPT and PsicAP. Results: The IAPT is a project for the pragmatic implementation of evidence-based psychological therapies in primary care. PsicAP is a randomized clinical trial whose results demonstrated that adding a psychological treatment (seven group sessions of transdiagnostic cognitive-behavioural therapy) to treatment-as-usual (TAU) for anxiety and depression in the primary care setting was more effective and cost-effective than TAU alone. The therapeutic gains and the cost-effectiveness were maintained at a 12 months follow-up. Moreover, the percentage of reliably recovered patients was comparable to the numbers from the IAPT. Conclusions: This brief psychological treatment should be implemented in the Spanish public health system, similar to the precedent set by the IAPT initiative.

A total of 178 patients completed the GAD-7 and were administered the Composite International Diagnostic Interview (CIDI) for DSM-IV Axis I Disorders, which was used as a reference standard. Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios were calculated. A cutoff of 10 yielded a sensitivity of .87, a specificity of .78, a positive predictive value of .93, a negative predictive value of .64, a positive likelihood ratio of 3.96 a negative likelihood ratio of .17 and Younden's Index of .65. The GAD-7 performed very well with a cutoff value of 10, the most frequently used cutoff point. Thus, a computerized version of the GAD-7 is an excellent screening tool for detecting general anxiety disorder in Spanish primary care settings.

However, there is no previous information on the key (bridge) symptoms that maintain comorbidity. The current study aimed to identify symptoms that may play a linking role in bridging comorbidity among EDs from a network analysis perspective. A sample of adult primary care patients (N = 1704) with symptoms of EDs was assessed using the Patient Health Questionnaire (PHQ). Network analysis was applied to examine the network structure, communities, expected influence, and bridge symptoms between depressive, anxiety, and somatic symptoms. Sad mood and low energy were the most central symptoms. Furthermore, low energy, fainting spells, sad mood, and restlessness were detected as prominent bridge symptoms between anxiety, depression, and somatic symptoms. These bridge symptoms could be therapeutic targets for early intervention and prevent the development of comorbidity among EDs. The results of this research highlight the importance of symptom-specific functional properties for the activation of communities within EDs, providing new insights on a complex phenomenon such as comorbidity.

To date, however, no RCTs have been conducted to compare TD-CBT to another active intervention in this setting. Our aim is to conduct a single-blind RCT to compare group TD-CBT plus TAU to progressive muscle relaxation (PMR) plus TAU in adults (age 18 to 65 years) with a suspected emotional disorder. We expect that TD-CBT + TAU will be more cost-effective than TAU + PMR, and that these gains will be maintained at the 12-month follow-up. Seven therapy sessions (1.5 hours each) will be offered over a 24-week period. The study will be carried out at four primary care centres in Cantabria, Spain. The study will take a societal perspective. Psychological assessments will be made at three time points: baseline, post-treatment, and at 12-months. The following variables will be evaluated: clinical symptoms (anxiety, depression, and/or somatic); functioning; quality of life (QoL); cognitive-emotional factors (rumination, worry, attentional and interpretative biases, emotion regulation and meta-cognitive beliefs); and satisfaction with treatment. Data on health service use, medications, and sick days will be obtained from electronic medical records. Primary outcome measures will include: incremental cost-PLOS ONE

El ensayo clínico PsicAP demostró que añadir 7 sesiones de entrenamiento cognitivo-conductual en grupo con enfoque transdiagnóstico al tratamiento habitual de trastornos emocionales en pacientes adultos de atención primaria aumentó la eficacia y coste-efectividad para reducir los niveles de síntomas, redujo la discapacidad y mejoró la calidad de vida. En este trabajo se describen esas 7 sesiones del protocolo PsicAP de tratamiento transdiagnóstico, dirigido a la intervención sobre los factores comunes a los distintos trastornos: las distorsiones cognitivas y las estrategias de regulación emocional. Se trata de una intervención basada en el aprendizaje mediante psicoeducación, reestructuración cognitiva, relajación, técnicas conductuales y prevención de recaídas. Se concluye argumentando sobre la utilidad de este protocolo para reducir la brecha entre investigación y práctica clínica, algo nece...

BACKGROUND The empirical evidence accumulated on the efficacy, effectiveness, and efficiency of psychotherapeutic treatments in children and adolescents calls for an update. The main goal of this paper objective was to carry out a selective review of empirically supported psychological treatments for a variety of common psychological disorders and problems in childhood and adolescence. METHOD A review was carried out of the psychological treatments for different psychological disorders and problems in social-emotional or behavioral adjustment in the child-adolescent population according to the Spanish National Health System (Clinical Practice Guidelines) levels of evidence and degrees of recommendation. RESULTS The findings suggest that psychological treatments have empirical support for addressing a wide range of psychological problems in these developmental stages. The degree of empirical support ranges from low to high depending on the phenomenon analyzed. The review suggests unequal progress in the different fields of intervention. CONCLUSIONS From this update, psychologists will be able to make informed decisions when implementing those empirically supported treatments to address the problems that occur in childhood and adolescence.

Transdiagnostic cognitive behaviour therapy (TD-CBT) is a promising treatment of emotional disorders. In this study, we evaluated several emotion regulation strategies as potential mediators of treatment outcomes in a clinical sample of primary care. METHODS A total of 1061 primary care patients were included in a randomized clinical trial comparing treatment-as-usual (TAU) to TD-CBT+TAU. Of these, 631 (TAU=316; TD-CBT+TAU=315) completed the full treatment and all pre- and post-treatment scales to assess symptoms (anxiety, depression, somatization), emotion regulation strategies (worry, rumination, negative metacognition, suppression, cognitive reappraisal), overall functioning, and quality of life (QoL). RESULTS Treatment and direct effects showed that TD-CBT+TAU was superior to TAU alone. On the multivariate analysis of indirect effects, three maladaptive strategies (worry, rumination and negative metacognition) had significant effects on all emotional symptoms. Suppression was also significant for depression. Rumination and negative metacognition were the only significant mediators of functioning, while only negative metacognition was significant for QoL. Reappraisal had no effect on any outcome. LIMITATIONS We focused mainly on maladaptive cognitive emotion regulation strategies and only studied one behavioural strategy (suppression) and one adaptive strategy (reappraisal). CONCLUSIONS Targeting certain maladaptive emotion regulation strategies (worry, rumination, suppression, negative metacognition) as mediators for treatment with TD-CBT could reduce emotional symptoms and improve well-being. Negative metacognition was the most transdiagnostic strategy, whereas an adaptive strategy such as reappraisal was not a mediator. Thus, maladaptive emotion regulation strategies are key mediators in transdiagnostic therapy for emotional disorders in primary care.

The aim of this study was to evaluate several key psychometric properties of the Sheehan Disability Scale (SDS) in patients with or without MDD and varying degrees of symptom severity using the Patient Health Questionnaire-9 (PHQ-9). METHOD A total of 1,704 PC patients participating in the PsicAP clinical trial completed the SDS and PHQ-9. We evaluated the factor structure, measurement invariance across gender, internal consistency, and the discriminative and predictive validity. RESULTS Confirmatory factor analyses revealed a unifactorial model of the SDS containing 4 items (SDS-4) with the best model fit (CFI: .99; GFI: .99; TLI: 96; RMSEA: .10). This model contained the three life domain items (work, family, and social life) plus perceived stress (PS) with significant loadings. The internal consistency of the SDS-4 was acceptable in...

This study aimed to establish the symptom structure of the Generalized Anxiety Disorder scale (GAD-7) using a novel network approach in combination with traditional analytical tools. METHODS A sample of 1704 primary care patients with emotional disorders (i.e., anxiety, depression, and/or somatization) completed the GAD-7 to report their anxiety symptoms. We examined the GAD-7 structure using exploratory graph analysis (EGA) compared to exploratory factor analysis (EFA) and confirmatory factor analysis. RESULTS The EFA results showed a one-factor solution, but EGA revealed a two-factor solution (cognitive-emotional and somatic). "Worrying too much" and "difficulty relaxing" were the most relevant symptoms. CONCLUSIONS The results support the possible distinction between the somatic and cognitive-emotional components of the GAD-7, thus permitting more specific screening in primary care settings.

We also sought to explore the potential contribution of cognitive variables to help differentiate between PD and PD + MDD. This was a subgroup analysis of 331 patients with PD symptoms who were included in the PsicAP clinical trial. All participants completed scales to evaluate panic, depression, somatization, cognitive and performance variables. A univariate analysis showed significant differences (p < .01) between the groups (PD vs PD + MDD) in clinical variables. Somatization was the best predictor of comorbid PD + MDD (β = .346; p < .01). Cognitive variables do not appear to play an essential role in predicting the presence of depressive symptoms in people with a screen positive for PD. These findings appear to support a transdiagnostic tre...

BACKGROUND Psychological treatments have shown their efficacy, effectiveness, and efficiency in dealing with mental disorders. However, considering the scientific knowledge generated in recent years, in the Spanish context, there are no updating studies about empirically supported psychological treatments. The main goal was to carry out a selective review of the main empirically supported psychological treatments for mental disorders in adults. METHOD Levels of evidence and degrees of recommendation were collected based on the criteria proposed by the Spanish National Health System (Clinical Practice Guidelines) for different psychological disorders. RESULTS The results indicate that psychological treatments have empirical support for the approach to a wide range of psychological disorders. These levels of empirical evidence gathered range from low to high depending on the psychological disorder analysed. The re...

We aimed to determine whether a transdiagnostic psychological therapy plus treatment-as-usual (TAU) is more efficacious than TAU alone in primary care adult patients.MethodsA randomized, two-arm, single-blind clinical trial was conducted in 22 primary care centres in Spain. A total of 1061 adult patients with emotional disorders were enrolled. The transdiagnostic protocol (n = 527) consisted of seven 90-min sessions (8–10 patients) delivered over a 12–14-week period. TAU (n = 534) consisted of regular consultations with a general practitioner. Primary outcome measures were self-reported symptoms of anxiety, depression, and somatizations. Secondary outcome measures were functioning and quality of life. Patients were assessed at baseline, post-treatment, and at 3, 6, and 12 months. Intention-to-treat and per-protocol analyses were performed.ResultsPost-treatment primary outcomes were significantly better in the transd...

However, little is known about possible moderators or predictors of treatment outcome. We aimed to explore the potential predictors and moderators of outcome in a large multicentre randomized controlled trial comparing TD-GCBT plus treatment as usual (TAU) to TAU alone. METHOD Putative demographic and baseline clinical variables were examined using the PROCESS macro as potential predictors/moderators of depressive and anxiety symptoms at posttreatment and 1-year follow-up. RESULTS Analyses were based on a study completer sample of 1061 participants randomized to TD-CBT + TAU (n = 527) or TAU alone (n = 534), with 631 participants assessed at the posttreatment evaluation and 388 at the 1-year follow-up. Individuals working or with a partner among sociodemographic variables, and higher baseline comorbidities and more severity of symptoms among clinical variables obtained more benefits from adding TDCBT to TAU. Those taking medication before treatment obtained less benefits from the TD-GCBT than those without prescribed antidepressant medications, after controlling for baseline severity of symptoms. Overall, the moderating effect of clinical (but not sociodemographic) variables remained at 1-year follow-up. CONCLUSION Findings support largely the generalization of the TD-GCBT for emotional disorders in primary care to a variety of sociodemographic and clinical groups. However, TD-GCBT seems to work to a greater extent for those individuals with a more severe clinical profile. Providing TD-GCBT before prescribing antidepressant medication and while people are still working may enhance the effects of adding this psychological treatment to TAU in primary care.
