The single case archive: Review of a multitheoretical online database of published peer-reviewed single-case studies.

Case study methods are increasingly recognized as crucial methods to enhance understanding of the complexity of psychotherapy processes and as way to bridge the science-practice gap. The Single Case Archive (SCA) was constructed to facilitate access to the existing field of case study research for academic, clinical, and educational purposes. Cases were selected through systematic screening of relevant peer-reviewed journals in the field of psychotherapy research and rigorous snowball sampling. All cases meeting inclusion criteria were inventoried using the Inventory for Basic Information in Single Cases that maps study, patient, therapist, and therapy characteristics. About 3,471 cases from 175 peer-reviewed journals published between 1955 and 2019 were included in the SCA database. The SCA comprises cases from different theoretical backgrounds, discussing patients from different age categories, with different presenting problems going through a diversity of psychotherapeutic treatments that are studied using a range of methods. Cases differ strongly with respect to the amount of information that is present in the case study, and the field should pay more attention to ethical considerations like informed consent and providing relevant basic descriptive information. An online platform makes the SCA database searchable by researchers, clinicians, and students. In conclusion, the SCA is a unique resource that makes case studies more easily accessible, facilitates meta-studies and reviews of case studies, and stimulates methodological developments in the field of case study research.

Interpersonal dynamics and therapeutic relationship in patients with functional somatic syndromes: A metasynthesis of case studies.

Patients with functional somatic syndromes (FSS) often display troubled relationships with health care providers, psychotherapists, and significant others. Research shows that patients' history of trauma, attachment disturbances, and mentalization deficits may result in the emergence of maladaptive interpersonal patterns, which may later contribute to the onset and maintenance of FSS, "doctor hopping," and dropout in psychotherapy. As the nature and therapeutic consequences of such maladaptive interpersonal patterns in FSS cannot be understood sufficiently by quantitative methods alone, there is a need for in-depth qualitative research. To address this issue, we conducted a metasynthesis of 23 published case studies of patients with FSS from various psychotherapeutic orientations. Results show that patients with FSS from our sample perceived others as unreliable, that is, unavailable, overcontrolling, and overprotective. To adapt to such unreliable others, patients attempted to please and to control them. Patients also suppressed their emotional awareness and expression. Although alexithymia could also play a role, the primary reason for emotional avoidance seemed to be interpersonal in nature, that is, patients were avoiding negative emotions in order to please and control the unreliable others. The onset and worsening of FSS were associated with both interpersonal and physical triggers. Showing signs of physical or emotional distress led to more rejection, overcontrol, and overprotection from unreliable others, which could create a "vicious circle." Our results suggest that offering a more interpersonal perspective on emotion regulation difficulties would be beneficial for patients with FSS, counselors, psychotherapists, and other health care professionals.

Countertransference Processes in Psychodynamic Therapy with Dependent (Anaclitic) Depressed Patients: A Qualitative Study Using Supervision Data.

Although Blatt's two-polarity model of depression has suggested that patients' interpersonal styles may shape countertransference phenomena in psychotherapy, empirical research on this topic has remained scarce. This article provides an in-depth study of countertransference processes in clinical work with dependent (anaclitic) depressed patients using a qualitative methodology. Thematic analysis of narrative material of psychodynamic therapists discussing patient cases during supervision (n = 7) resulted in four recurrent themes: "empathy, compassion, and support," "anxiety, feeling overwhelmed, and protection," "frustration, irritation, and confrontation," and "inadequacy, incompetence, and fatalism." We found that these countertransference processes mainly revolved around perceived adaptive and maladaptive aspects of patients' relational functioning. Regarding clinical practice, our study suggests that therapists can use countertransference to determine in which position they are maneuvered by patients, although we caution against the exclusive use of subjectively informed data as a benchmark in the diagnostic and treatment process. We conclude that further in-depth research on countertransference and personality styles is needed to identify pitfalls in the treatment of depression.

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.
