Interactions between Obsessional Symptoms and Interpersonal Ambivalences in Psychodynamic Therapy: An Empirical Case Study

Developing psychoanalytic case conceptualization skills through didactic teaching: A randomized controlled trial

OBJECTIVE

Time-limited didactic interventions have been shown to be effective in developing "generic" case conceptualization skills. The objective of this study is to test whether similar interventions can be used to develop case conceptualization skills that are "specific" to a treatment modality.

METHOD

University psychology students were randomized to a target (n = 62) or a control group (n = 62). The target group received a training on psychoanalytic case conceptualization skills based on the newly-developed operators model. The control group received a training on generic case conceptualization skills based on the well-established 5 Ps model.

RESULTS

The students' self-efficacy for case conceptualization significantly increased in both groups. However, students in the target group reported a significantly greater increase in psychoanalytic case conceptualization skills and in their ability to make clinical inferences. The teaching method, as well as the case conceptualization models, were acceptable to students. However, the 5 Ps model was significantly more acceptable to students than the operators model.

CONCLUSIONS

This is the first RCT to provide evidence that psychoanalytic case conceptualization skills can be developed through didactic teaching and that they constitute a specific set of skills that are not developed by learning generic case conceptualization skills.

Extending Blatt's two-polarity model of personality development to dissociative identity disorder: a theory-building case study

In this theory-building case study, we investigate Blatt's two-polarity model of personality development according to which psychopathology is a consequence of an unbalance between the two developmental lines of interpersonal relatedness and self-definition. Anaclitic psychopathology, such as schizophrenia, histrionic, dependent, and borderline personality disorders, is associated with an excessive and rigid emphasis on interpersonal relatedness. In this theory-building case study, we examine whether this model can be extended to dissociative identity disorder (DID). The patient is a 23-year old Caucasian man who suffers from periodic episodes of dissociation. Consensual qualitative research for case studies is used to quantitatively and qualitatively describe the interplay between symptomatic and interpersonal evolutions throughout 41 sessions of supportive-expressive psychoanalytic psychotherapy. In line with the two-polarity model of personality development, close associations between symptoms of dissociation and dependent interpersonal dynamics were observed. Psychoanalytic interventions focusing on elaboration of the subjective meanings of (past and anticipated) dissociations, and on working through core interpersonal conflicts, are followed by transformations in the patient's interpersonal stances and subjective well-being. No new dissociative episodes were reported during the follow-up assessment three and a half years after the completion of treatment. This case study demonstrates that DID is a form of anaclitic psychopathology as it is associated with a predominant tendency to interpersonal relatedness.

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.

Validity Beyond Measurement: Why Psychometric Validity Is Insufficient for Valid Psychotherapy Research

In psychotherapy research, "validity" is canonically understood as the capacity of a test to measure what is purported to measure. However, we argue that this psychometric understanding of validity prohibits working researchers from considering the validity of their research. Psychotherapy researchers often use measures with a different epistemic goal than test developers intended, for example when a depression symptom measure is used to indicate "treatment success" (cf. outcome measurement for evidence-based treatment). However, the validity of a measure does not cover the validity of its use as operationalization of another target concept within a research procedure, nor the validity of its function toward an epistemic goal. In this paper, we discuss the importance of considering validity of the epistemic process beyond the validity of measures per se, based on an empirical case example from our psychotherapy study ("SCS", Cornelis et al., 2017). We discuss why the psychometric understanding of validity is insufficient in covering epistemic validity, and we evaluate to what extent the available terminology regarding validity of research is sufficient for working researchers to accurately consider the validity of their overall epistemic process. As psychotherapy research is meant to offer a sound evidence-base for clinical practice, we argue that it is vital that psychotherapy researchers are able to discuss the validity of the epistemic choices made to serve the clinical goal.

Beyond Clinical Case Studies in Psychoanalysis: A Review of Psychoanalytic Empirical Single Case Studies Published in ISI-Ranked Journals

Single case studies are at the origin of both theory development and research in the field of psychoanalysis and psychotherapy. While clinical case studies are the hallmark of psychoanalytic theory and practice, their scientific value has been strongly criticized. To address problems with the subjective bias of retrospective therapist reports and uncontrollability of clinical case studies, systematic approaches to investigate psychotherapy process and outcome at the level of the single case have been developed. Such empirical case studies are also able to bridge the famous gap between academic research and clinical practice as they provide clinically relevant insights into how psychotherapy works. This study presents a review of psychoanalytic empirical case studies published in ISI-ranked journals and maps the characteristics of the study, therapist, patient en therapies that are investigated. Empirical case studies increased in quantity and quality (amount of information and systematization) over time. While future studies could pay more attention to providing contextual information on therapist characteristics and informed consent considerations, the available literature provides a basis to conduct meta-studies of single cases and as such contribute to knowledge aggregation.
