Personalized Psychotherapy for Outpatients with Major Depression and Anxiety Disorders: Transdiagnostic Versus Diagnosis-Specific Group Cognitive Behavioural Therapy

Defining and operationalizing personalized psychological treatment - a systematic literature review

This systematic literature review aimed to propose a definition of personalized psychological treatment and to suggest how the definition can be operationalized. PsycINFO, Cochrane Library, MEDLINE and EMBASE were searched up to 11 December 2023 for studies in which a definition of personalized psychological treatment was included or a systematic operationalization of personalized psychological treatment was described. Based on a narrative synthesis of the collected definitions, summary categories were developed that informed the proposed definition. Operationalizations were described according to what aspect of treatment, how and when treatment was personalized. The extent to which the operationalizations deviated from the proposed definition was assessed. Thirty-four studies with definitions and 200 with operationalizations were included. The following definition was proposed: personalized psychological treatment aims to optimize treatment outcome for the individual patient by tailoring treatment to unique or specific needs, preferences or other characteristics and includes a systematic adaptation of treatment or a differentiation between treatment strategies. Based on the operationalizations, timing of personalization, specification of the systematic approach and treatment elements that could be personalized were added to the proposed definition. Evidence-based personalization of psychological treatments can be enhanced by clear operationalization based on a comprehensive definition of personalization.

Individual-Specific Animated Profiles of Mental Health

How important is the timing of the pretreatment evaluation? If we consider mental health to be a relatively fixed condition, the specific timing (e.g., day, hour) of the evaluation is immaterial and often determined on the basis of technical considerations. Indeed, the fundamental assumption underlying the vast majority of psychotherapy research and practice is that mental health is a state that can be captured in a one-dimensional snapshot. If this fundamental assumption, underlying 80 years of empirical research and practice, is incorrect, it may help explain why for decades psychotherapy failed to rise above the 50% efficacy rate in the treatment of mental-health disorders, especially depression, a heterogeneous disorder and the leading cause of disability worldwide. Based on recent studies suggesting within-individual dynamics, this article proposes that mental health and its underlying therapeutic mechanisms have underlying intrinsic dynamics that manifest across dimensions. Computational psychotherapy is needed to develop individual-specific pretreatment animated profiles of mental health. Such individual-specific animated profiles are expected to improve the ability to select the optimal treatment for each patient, devise adequate treatment plans, and adjust them on the basis of ongoing evaluations of mental-health dynamics, creating a new understanding of therapeutic change as a transition toward a more adaptive animated profile.

Trait and symptom change in group cognitive behaviour therapy for anxiety and depression

Personality traits underlying both anxiety disorders and depression are more malleable than previously presumed. This study examined associations between changes in personality traits (i.e. negative affectivity and detachment) and alleviation of anxiety and depression symptoms following cognitive behaviour therapy (CBT). We hypothesized that decreases in negative affectivity would predict alleviation of depression and anxiety symptoms and decreases in detachment would predict decreases in depression and, to a lesser degree, anxiety symptoms. Data (N = 156) were collected in a randomized controlled trial comparing transdiagnostic and diagnosis-specific group CBT for patients with major depressive disorder, social anxiety disorder, panic disorder or agoraphobia. We assessed personality traits using the Personality Inventory for DSM-5 (PID-5) and symptoms with the Hopkins Symptom Checklist 25-item scale (SCL). Prediction was based on regression analyses. We found that decreases in negative affectivity predicted lower levels of depression and anxiety symptoms while decreases in detachment only predicted lower levels of depression symptoms. The findings substantiate current efforts to explicate the dynamic interplay between personality traits and symptoms and support the existing focus on targeting negative affectivity and detachment in therapy for anxiety disorders and depression. The trial is registered at clinicaltrials.gov (ID NCT02954731).

Evaluation of a male-specific psychotherapeutic program for major depressive disorder compared to cognitive behavioral therapy and waitlist: study protocol for a six-arm randomized clinical superiority trial examining depressed eugonadal and hypogonadal men receiving testosterone

Background

Treatment of major depressive disorder (MDD) in men is complicated by the endorsement of traditional masculinity ideologies (TMI) often leading to reluctance toward psychotherapy, therapy interfering processes, or premature termination. In addition, it has been shown that men with MDD have a significantly increased risk of being hypogonadal (e.g., total testosterone levels <12.1 nmoL/L). Therefore, it is recommended to examine depressed men with regard to their testosterone status and if hypogonadism is present to combine psychotherapy with testosterone treatment (TT).

Aim

This project aims to evaluate a male-specific psychotherapeutic program (MSPP) for MDD in depressed eugonadal and hypogonadal men receiving testosterone in comparison to a standard cognitive behavioral therapy (CBT) for MDD and a Waitlist.

Methods

The study presents a 2×3 factorial study design. In total, 144 men aged between 25 and 50 will be stratified by testosterone status (eugonadal/hypogonadal) and then randomized into one of the three conditions (MSPP, CBT, or Waitlist). Additionally, a healthy control group of 100 men will be recruited, which will undergo only baseline assessments. Both standardized psychotherapy programs will encompass 18 sessions delivered in a weekly manner. Aligned with the TT-related medical visits of the 72 hypogonadal men, all participants will be followed up with clinical assessments and bio sampling at weeks 0, 6, 15, 24, and 36.

Expected results

Compared to Waitlist control groups, treatment groups are expected to be more effective and efficacious (depression score reduction of ≥50%) at week 24 and at the follow-up at week 36. The MSPP is expected to show higher effectiveness and efficacy for depressive symptoms and higher acceptability (lower dropout rate) as compared to CBT.

Discussion

This study represents the first attempt to test a male-specific psychotherapy for MDD in a single-setting compared to standard CBT and a Waitlist control condition using randomized clinical trial methodology. In addition, the potential positive adjunct effect of psychotherapy to TT in reducing depressive burden and improving quality of life in hypogonadal depressed men represents a neglected research area and might introduce new hypogonadism screening procedures in depressed men and combined treatment approaches for depressed men suffering from hypogonadism. Limitations are the rigorous inclusion and exclusion criteria, which limit the generalizability of the study results to first episode treatment naïve depressed men.

The Spanish version of the reflective functioning questionnaire: Validity data in the general population and individuals with personality disorders

INTRODUCTION

Mentalization or reflective functioning (RF) is the capacity to interpret oneself or the others in terms of internal mental states. Its failures have been linked to several mental disorders and interventions improving RF have a therapeutic effect. Mentalizing capacity of the parents influences the children's attachment. The Reflective Functioning Questionnaire (RFQ-8) is a widely used tool for the assessment of RF. No instrument is available to assess general RF in Spanish-speaking samples. The aim of this study is to develop a Spanish version of the RFQ-8 and to evaluate its reliability and validity in the general population and in individuals with personality disorders.

METHODS

602 non-clinical and 41 personality disordered participants completed a Spanish translation of the RFQ and a battery of self-reported questionnaires assessing several RF related constructs (alexithymia, perspective taking, identity diffusion and mindfulness), psychopathology (general and specific) and interpersonal problems. Temporal stability was tested in a non-clinical sub-sample of 113 participants.

RESULTS

Exploratory and confirmatory factor analyses suggested a one-factor structure in the Spanish version of the RFQ-8. RFQ-8 understood as a single scale was tested, with low scorings reflecting genuine mentalizing, and high scorings uncertainty. The questionnaire showed good internal consistence in both samples and moderate temporal stability in non-clinical sample. RFQ correlated significantly with identity diffusion, alexithymia, and general psychopathology in both samples; and with mindfulness, perspective taking, and interpersonal problems in clinical sample. Mean values of the scale were significantly higher in the clinical group.

DISCUSSION

This study provides evidence that the Spanish version of the RFQ-8, understood as a single scale, has an adequate reliability and validity assessing failures in reflective functioning (i.e., hypomentalization) in general population and personality disorders.

Emotion dysregulation and neuroticism as moderators of group Unified Protocol effectiveness outcomes for treating emotional disorders

BACKGROUND

The personality dimension neuroticism and difficulties in emotional regulation (ER) are two variables closely related to the onset, course, and maintenance of emotional disorders (EDs). The Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP) is a treatment specifically designed to address neuroticism by training in adaptive ER skills and has been shown to be effective in reducing difficulties in ER. However, the specific impact of these variables on treatment outcomes is not entirely clear. The aim of the present study was to explore the moderating role of neuroticism and difficulties in ER regarding the evolution of depressive and anxiety symptoms and quality of life.

METHODS

This secondary study included 140 participants diagnosed with EDs, who received the UP in group format as part of an RCT being conducted in different Spanish Public Mental Health Units.

RESULTS

The results of this study found that high scores in neuroticism and difficulties in ER were associated with greater severity of depression and anxiety symptomatology, and with poorer quality of life. In addition, difficulties in ER moderated the efficacy of UP regarding anxiety symptoms, and quality of life. No moderating effects were found for depression (p > 0.5).

LIMITATIONS

We only evaluated two moderators that may influence UP effectivenes; other key moderators should be analyzed in future.

CONCLUSIONS

The identification of specific moderators affecting transdiagnostic interventions outcomes will allow the development of personalized interventions and provide useful information to improve the psychopathology and well-being of people with EDs.

The effect of a solution-oriented therapy on the depression levels and the perceived social support of depressive patients

BACKGROUND

This study was executed to evaluate the effect of the solution-oriented therapy programme on the depression levels and the perceived social support of depressive patients METHOD: The study was designed as a randomized controlled trial with a pre-test and post-test control group and repeated measures. The Solution-Oriented Therapy Programme was implemented in a total of 6 to 10 sessions with the patients of experimental group.

RESULTS

There were no statistically significant differences between the mean BDI and PSSI scores of the experimental and control groups before the programme. At one week after the programme (29.89 ± 4.15) and after 3 months (31.71 ± 3.72), the mean of the BDI grades of the individuals in the experimental group were significantly lower than was that of the individuals in the control group. In the study group, the mean PSSI scores significantly increased at one week after programme (50.79 ± 10.81) and decreased (46.61 ± 10.37) at after 3 months.

CONCLUSION

The execution of Solution-Oriented Therapy Programme with the depressive patients should be done by the psychiatric nurses within the scope of the services that psychiatric care units serve.

Transdiagnostic versus Diagnosis-Specific Group Cognitive Behavioral Therapy for Anxiety Disorders and Depression: A Randomized Controlled Trial

INTRODUCTION

The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) delivered in a group format could facilitate the implementation of evidence-based psychological treatments.

OBJECTIVE

This study compared the efficacy of group UP and diagnosis-specific cognitive behavioral therapy (dCBT) for anxiety and depression in outpatient mental health services.

METHODS

In this pragmatic, multi-center, single-blinded, non-inferiority, randomized controlled trial (RCT), we assigned 291 patients with major depressive disorder, social anxiety disorder, panic disorder, or agoraphobia to 14 weekly sessions in mixed-diagnosis UP or single-diagnosis dCBT groups. The primary test was non-inferiority, using a priori criteria, on the World Health Organisation 5 Well-Being Index (WHO-5) at the end of the treatment. Secondary outcomes were functioning and symptoms. We assessed outcomes at baseline, end-of-treatment, and at a 6-month follow-up. A modified per-protocol analysis was performed.

RESULTS

At end-of-treatment, WHO-5 mean scores for patients in UP (n = 148) were non-inferior to those of patients in dCBT (n = 143; mean difference -2.94; 95% CI -8.10 to 2.21). Results were inconclusive for the WHO-5 at the 6-month follow-up. Results for secondary outcomes were non-inferior at end-of-treatment and the 6-month follow-up. Client satisfaction and rates of attrition, response, remission, and deterioration were similar across conditions.

CONCLUSIONS

This RCT demonstrated non-inferior acute-phase outcomes of group-delivered UP compared with dCBT for major depressive disorder, social anxiety disorder, panic disorder, and agoraphobia in outpatient mental health services. The long-term effects of UP on well-being need further investigation. If study findings are replicated, UP should be considered a viable alternative to dCBT for common anxiety disorders and depression in outpatient mental health services.

Acceptability of and intention to use the Unified Protocol delivered in group format in the Spanish Public Health System

BACKGROUND

The high prevalence of emotional disorders leads to a high demand for mental care which results in high costs and long waiting lists in public mental health settings. The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) is a recent emotion-regulation-based intervention that can be a cost-effective solution in public mental health settings due its transdiagnostic approach and the possibility to apply it in group format. However, the acceptability by mental healthcare professionals (MHCPs) delivering the UP in group format has not been explored.

METHODS

Thirty-three MHCPs, grouped into MHCPs without previous experience and MHCPs with experience in delivering the UP, were asked about aspects of acceptability and intention to use. Quantitative analysis was carried out to explore MHCPs acceptability. Furthermore, qualitative opinion about UP were collected through a SWOT (strengths, weaknesses, opportunities, threats) analysis to explore MHCPs opinion of delivering the UP intervention in a group format, within the Spanish Public Mental Health System.

RESULTS

The results showed high scores in all acceptability dimensions and intention to use in the future. SWOT analysis showed strengths and opportunities focusing on its transdiagnostic nature and the cost-effective benefits of group treatment, and weaknesses and threats related to the limited material and human resources.

CONCLUSIONS

Findings indicate high acceptability of the UP by MHCPs working within the Spanish Public Mental Health System and also identified areas for improvements. In order to enhance the dissemination and implementation of the UP, it is essential to consider MHCPs' perceptions and to be open to their suggestions.

The Role of Perseverative Cognition for Both Mental and Somatic Disorders in a Naturalistic Psychiatric Patient Sample

OBJECTIVE

Perseverative cognition (PC) is the repeated or long-term activation of the cognitive representation of psychological stressors and is associated with prolonged stress including somatic and mental consequences. Hence, PC might represent a cognitive process linking mental and somatic pathology, but current research on this link is limited by investigating healthy samples, markers of somatic disease, and single disorders. The present study explored the importance of PC for different mental and somatic disorders in psychiatric patients.

METHODS

Data from 260 naturalistic psychiatric outpatients were used. Psychiatric diagnoses were based on structured clinical interviews. Somatic diseases were assessed using a well-validated questionnaire and were clustered into (cardio)vascular and immune/endocrine diseases. PC was operationalized using the Perseverative Thinking Questionnaire (PTQ).

RESULTS

Multiple regression complemented with relative importance analyses showed that the PTQ total and subscale scores were associated with the presence of mood disorders, addiction, and anxiety. Unexpectedly, no relatively important associations were found between the PTQ and autism spectrum disorder, attention-deficit/hyperactivity disorder, or somatic disease.

CONCLUSIONS

Our data complement previous work linking PC to stress-related mental disorders but question its immediate role in neurodevelopmental and somatic disorders. Targeting PC in the treatment of mood disorders and perhaps also in addiction seems promising.

Kölner Fragebogen zur Sprachlosigkeit

Hintergrund

Mit dem Kölner Fragebogen zur Sprachlosigkeit (KFS) liegt erstmals ein validiertes Erhebungsinstrument zur Erfassung von Sprachlosigkeit vor. Die empirische Prüfung des KFS hinsichtlich seiner Eignung zur validen Unterscheidung von Personen mit gering und hoch ausgeprägter Sprachlosigkeit ist von zentraler Bedeutung für den klinischen Einsatz des Instruments.

Material und Methoden

Die Stichprobe umfasste die KFS-Daten von insgesamt 205 teilnehmenden Personen einer Onlineerhebung. Mithilfe mehrerer inferenzstatistischer Verfahren wurden die prädiktiven Eigenschaften des KFS-Item 12 analysiert, um es für die Bestimmung eines Schwellenwerts beim Einsatz des KFS nutzbar zu machen. Basierend auf dem 75. Perzentil des KFS-Item 12 erfolgte eine Dichotomisierung der Stichprobe mit anschließender „Receiver-operating-characteristic“(ROC)-Analyse zur KFS-Gesamtskala.

Ergebnisse

Die Ergebnisse der ROC-Analyse („area under the curve“ [AUC]: 0,863; p < 0,001) ergaben bei Verwendung des Youden-Index den optimalen Schwellenwert von >29, mit einer Sensitivität von 76 % und einer Spezifität von 79 % für die Gesamtskala des KFS.

Diskussion

Der Schwellenwert der KFS-Gesamtskala ist zur Differenzierung von Personen mit gering oder stark ausgeprägter Sprachlosigkeit geeignet. Das Item 12 des KFS kann zudem als Prädiktor einer potenziellen Sprachlosigkeit herangezogen werden.

On the efficacy of the unified protocol for transdiagnostic treatment of emotional disorders: A systematic review and meta-analysis

In recent years a large array of treatment protocols conceptualized as transdiagnostic have been developed with clinical and practical advantages compared to traditional single-disorder protocols. Within this panorama, the Transdiagnostic Unified Protocol (UP) of Emotional Disorders was developed aimed at treating the negative affective processes underlying several diagnostic categories, and accounting for the covariance of different emotional disorders. The UP has been found to efficiently target the roots of these disorders leading to a reduction in symptoms of co-occurring disorders. However, several questions have marginally addressed in the previous studies, and some UP features still remain unexplored. The present meta-analysis aims at evaluating whether the UP results to significant changes in anxiety and depression symptoms severity in children, adolescents, and adults. 19 RCTs and 13 uncontrolled pre-post trials comprising 2183 patients/clients met inclusion criteria for meta-analysis. Large to moderate combined overall effect size for both depression plus anxiety were detected in the uncontrolled pre-post studies (g = 0.756) and in RTCs studies (g = 0.452), respectively. Large effect size at pre-treatment to 3-6-month follow-up was observed for combined depression plus anxiety (g = 1.113). Subgroup analysis suggested that UP treatment does not differ across the anxiety and depression self-report measures. Moreover, UP intervention outperformed both passive and active control conditions to treat negative affective syndromes. Meta-regression confirmed the moderate effects of therapist level of experience, the sample characteristics, and the UP-protocol adaptations. The findings indicate that the manualized UP treatment has potential to contribute to improving mental health outcomes, particularly of anxiety and depression.
