The Ghent Psychotherapy Study (GPS) on the differential efficacy of supportive-expressive and cognitive behavioral interventions in dependent and self-critical depressive patients: study protocol for a randomized controlled trial

Impact of personality style changes on CBT and PDT treatment responses in major depression

This study examines the influence of depressive personality styles on treatment responses in patients with major depression receiving cognitive behavioural therapy and psychodynamic therapy. We assessed changes in personality styles, including dependency, self-criticism, sociotropy, and autonomy, and their association with treatment response. Both treatment modalities led to significant reductions in self-criticism and sociotropy scores. Depressive symptom severity decreased overall, with a more pronounced reduction observed in the cognitive behavioural therapy group. Notably, reduced self-criticism and sociotropy were associated with better treatment outcomes in the cognitive behavioural therapy group. Our findings highlight the role of personality styles in influencing treatment outcomes for major depression. The study suggests an association between changes in personality styles and the reduction of symptoms. Our results support the idea that unique pathways of change are activated depending on the therapeutic intervention. These insights are critical in tailoring treatments to individual needs, addressing the central question of 'what works for whom'.

Depressive personality traits and temperament and character personality traits in a clinical sample: Results from regression and network analyses

Personality and psychopathology are highly relevant and easily relatable constructs. The current study investigated the relationships between dependency and self-criticism, sociotropy and autonomy depressive personality traits, and Cloninger's temperament and character personality traits postulated as vulnerability factors for depression, in relation to depressive and general psychopathology symptoms in a clinical sample of 100 patients diagnosed with major depressive disorder. The results showed that self-directedness, a character trait of the temperament and character model, was positively associated with dependency, self-criticism, sociotropy, and autonomy. Applying more in-depth analyses with regression models revealed associations between self-directedness and depressive personality styles dependency and sociotropy, and general psychopathology symptoms was a significant clinical indicator in these relationships. Going beyond the regression models, network analysis showed that self-directedness is associated with self-criticism, sociotropy, autonomy, and general psychopathology symptoms. The relationship between self-directedness and sociotropy, self-criticism and autonomy suggests that these depressive personality traits may be attributable to aspects of self-determination, maturity, responsibility, discipline, and self-acceptance. General psychopathology research informed by literature incorporating personality traits has far-reaching implications for understanding individual differences as well as increasing efforts to contribute to the amelioration of disabling psychological disorders like major depressive disorders.

What too strict a method obscures about the validity of outcome measures

Objective: To assess the outcome of psychotherapeutic treatments, psychotherapy researchers often compare pre- and post-treatment scores on self-report outcome measures. In this paper, the common assumption is challenged that pre-to-post decreasing and increasing outcome scores are indicative of successful and failed therapies, respectively.Method: The outcome of 29 psychotherapeutic treatments was evaluated by means of quantitative analysis of pre- and post-treatment scores on commonly used outcome measures (such as the Symptom Checklist-90-R, the Inventory of Interpersonal Problems, and the General Health Questionnaire-12), as well as through consensual qualitative research.Results: Overall, a moderate to low convergence between qualitative and quantitative evaluations of outcome was observed. Detailed analyses of six cases are presented in which pre-to-post comparisons of outcome measures proved misleading.Conclusions: It is concluded that psychotherapy outcome research might benefit from assessment strategies that are sensitive to the singularities of individual treatments and to the complexity of the phenomenon of therapeutic outcome. Furthermore, classical psychometric evaluations of the validity of outcome measures might be supplemented with less-systematic evaluations that take any contingent source of information on outcome into account.

How Speakers Orient to the Notable Absence of Talk: A Conversation Analytic Perspective on Silence in Psychodynamic Therapy

Silence has gained a prominent role in the field of psychotherapy because of its potential to facilitate a plethora of therapeutically beneficial processes within patients’ inner dynamics. This study examined the phenomenon from a conversation analytical perspective in order to investigate how silence emerges as an interactional accomplishment and how it attains interactional meaning by the speakers’ adjacent turns. We restricted our attention to one particular sequential context in which a patient’s turn comes to a point of possible completion and receives a continuer by the therapist upon which a substantial silence follows. The data collection consisted of 74 instances of such post-continuer silences. The analysis revealed that silence (1) can retroactively become part of a topic closure sequence, (2) can become shaped as an intra-topic silence, and (3) can be explicitly characterized as an activity in itself that is relevant for the therapy in process. Only in this last case, the absence of talk is actually treated as disruptive to the ongoing talk. Although silence is often seen as a therapeutic instrument that can be implemented intentionally and purposefully, our analysis demonstrated how it is co-constructed by speakers and indexically obtains meaning by adjacent turns of talk. In the ensuing turns, silence indeed shows to facilitate access to the patient’s subjective experience at unconscious levels.

The Influence of Interpersonal Patterns on the Therapy Process in a Case of Childhood Trauma

Research concerning the influence of core interpersonal patterns related to childhood trauma on the therapeutic process is scarce. We investigated interpersonal patterns at the start of treatment, changes in interpersonal patterns as treatment progressed, and the change process in a mixed-methods single case study of a supportive-expressive psychodynamic psychotherapy with a 33-year-old female with a history of childhood trauma. The patient showed a pervasive inability to open up towards others throughout the entire treatment, which is closely associated with others' actual or anticipated rejection, disrespect and disinterest. Excessive use of expressive interventions, which target interpersonal change, initially led to a worsening of the patient's condition. Via supportive and general interventions, symptom stabilization was achieved. The findings of this study suggest a thorough understanding of dominant interpersonal patterns is necessary to recognize their influence on the therapy process.

Adjuvant psychotherapy in early-stage bipolar disorder: study protocol for a randomized controlled trial

Background

Bipolar disorders are serious illnesses with a chronic course and a high rate of relapse. Typically, bipolar disorders onset during adolescence or early adulthood, with patients experiencing significant personal and social costs as a consequence of their illness. Despite this, to date, there is limited (controlled) evidence regarding the effectiveness of psychotherapy during the critical stages of the disorder (e.g., early onset). Some preliminary studies suggest that targeted, tailored early interventions in particular may improve disease prognosis. The proposed study examines the effectiveness of group psychotherapy on relapse prevention, global adaptive functioning, and neuropsychological functioning in early-stage bipolar disorder.

Methods

In this multicenter randomized controlled trial (RCT), 300 patients with bipolar disorder are randomized to one of two group psychotherapies: Specific Emotional-Cognitive Therapy (SECT; intervention group) or Emotion-Focused Supportive Therapy (EFST; active control group). Each therapy comprises of a total of 48-h sessions (delivered once a month) over a period of 4 months. Assessments take place at baseline (t1); 6 months follow-up, i.e., post-intervention (t2); 12 months follow-up (t3); and 18 months follow-up (t4), whereby 18 months follow-up is the primary time point of interest.

Discussion

The goal of this study is to test the effects of an innovative, specific group therapy relative to an active control condition in terms of rates of relapse, global functioning, and neuropsychological functioning. Pending the outcomes of the trial, it will be possible to establish a firm evidence base for accessible group psychotherapy adjuvant to routine psychiatric care for individuals with bipolar disorder.

Reformulating and Mirroring in Psychotherapy: A Conversation Analytic Perspective

The conversational actions of reformulating and mirroring constitute some of the core intervention techniques of psychotherapy. The purpose of the present study was to investigate the way in which therapists in cognitive-behavioral (CBT) and psychodynamic therapy (PDT) use reformulating and mirroring strategies to return patients’ prior talk and how their differential usage can be viewed in light of the respective manualized recommendations. A mixed methods approach was applied using qualitative data that derived from a RCT. The data collection consisted of 200 excerpts assembled from both treatment conditions. The method of Conversation Analysis was used to determine the practices that accomplished instances of reformulating and mirroring, and to examine their distinct implications for subsequent talk. The quantitative analysis revealed that cognitive-behavioral therapists are significantly more likely to use reformulations, which is in harmony with what is suggested in CBT’s treatment manuals. Psychodynamic therapists’ frequent use of transformative formulations is, by contrast, unexpected in regard to the suggestions of the treatment protocol, as these interventions steer toward topical closure. Compared to the CBT condition, psychodynamic therapists were still significantly more likely to rely on mirroring strategies, which are in line with PDT’s theoretical preference. Our findings raise the question whether alleged differences in treatment styles, as they are imposed by RCT methodology, are actually tangible in manual-guided clinical practice.

Core Interpersonal Patterns in Complex Trauma and the Process of Change in Psychodynamic Therapy: A Case Comparison Study

We performed a case comparison study to investigate the nature of interpersonal patterns in childhood trauma and the process of change therein. We analyzed three matching cases of childhood trauma that followed a psychodynamic treatment via a mixed-methods design. We found that (1) the core tendency to avoid negative reactions from others through passive behaviors emerged in all three cases, both in childhood and adulthood, (2) core interpersonal patterns transpired in the interaction between patient and therapist and thereby affected the therapeutic relationship, and (3) change ensued when a repetition of core interpersonal patterns was avoided and a new relational experience occurred. The accumulated findings across cases further resulted in several clinical implications and recommendations, such as the importance of the assessment of patients' (covert) conditions, responsiveness, supervision and facilitating patients' agency, and provided several avenues for further research.

Change processes underlying "good outcome": A qualitative study on recovered and improved patients' experiences in psychotherapy for major depression

Aim: Exploring change processes underlying "good outcome" in psychotherapy for major depression. We examined the perspectives of patients who "recovered" and "improved" (Jacobson & Truax) following time-limited CBT and PDT. Method: In the context of an RCT on the treatment of major depression, patients were selected based on their pre-post outcome scores on the BDI-II: we selected 28 patients who recovered and 19 who improved in terms of depressive symptoms. A grounded theory analysis was conducted on post-therapy client change interviews, resulting in an integrative conceptual model. Results: According to recovered and improved patients, change follows from an interaction between therapy, therapist, patient, and extra-therapeutic context. Both helping and hindering influences were mentioned within all four influencing factors. Differences between recovered and improved patients point at the role of patients' agency and patients' internal and external obstacles. However, patients marked as "improved" described heterogeneous experiences. CBT- and PDT-specific experiences were also observed, although our findings suggest the possible role of therapist-related influences. Conclusion: From patients' perspectives, various change processes underlie "good outcome" that do not necessarily imply an "all good process". This supports a holistic, multidimensional conceptualization of change processes in psychotherapy and calls for more fine-grained mixed-methods process-outcome research.

Perceived mechanisms of change in therapeutic yoga targeting psychological distress

INTRODUCTION

This study was designed to investigate yoga teachers' and yoga therapists' perceptions of the ways yoga is applied to treat symptoms of psychological distress, and identify the defining features, main components, and mechanisms of change in therapeutic practice.

METHODS

A qualitative design was employed. Six yoga teachers who had specific training and experience in teaching therapeutic yoga or practicing 'yoga therapy' took part in one-to-one interviews during which they gave accounts of their experiences of helping people cope with psychological distress through yoga. Participants' interviews were transcribed verbatim and were analysed using an integrative inductive-deductive thematic analysis.

RESULTS

Four key themes were identified in relation to the benefits of therapeutic yoga: Awareness, Choice, Relationships, and Tailoring.

CONCLUSIONS

The findings support previous research which suggests that individualised yoga therapy is a promising intervention, and may help to form a theoretical rationale for the future treatment of psychological distress with yoga.

No Change? A Grounded Theory Analysis of Depressed Patients' Perspectives on Non-improvement in Psychotherapy

Aim: Understanding the effects of psychotherapy is a crucial concern for both research and clinical practice, especially when outcome tends to be negative. Yet, while outcome is predominantly evaluated by means of quantitative pre-post outcome questionnaires, it remains unclear what this actually means for patients in their daily lives. To explore this meaning, it is imperative to combine treatment evaluation with quantitative and qualitative outcome measures. This study investigates the phenomenon of non-improvement in psychotherapy, by complementing quantitative pre-post outcome scores that indicate no reliable change in depression symptoms with a qualitative inquiry of patients' perspectives. Methods: The study took place in the context of a Randomised Controlled Trial evaluating time-limited psychodynamic and cognitive behavioral therapy for major depression. A mixed methods study was conducted including patients' pre-post outcome scores on the BDI-II-NL and post treatment Client Change Interviews. Nineteen patients whose data showed no reliable change in depression symptoms were selected. A grounded theory analysis was conducted on the transcripts of patients' interviews. Findings: From the patients' perspective, non-improvement can be understood as being stuck between knowing versus doing, resulting in a stalemate. Positive changes (mental stability, personal strength, and insight) were stimulated by therapy offering moments of self-reflection and guidance, the benevolent therapist approach and the context as important motivations. Remaining issues (ambition to change but inability to do so) were attributed to the therapy hitting its limits, patients' resistance and impossibility and the context as a source of distress. "No change" in outcome scores therefore seems to involve a "partial change" when considering the patients' perspectives. Conclusion: The study shows the value of integrating qualitative first-person analyses into standard quantitative outcome evaluation and particularly for understanding the phenomenon of non-improvement. It argues for more multi-method and multi-perspective research to gain a better understanding of (negative) outcome and treatment effects. Implications for both research and practice are discussed.
