Measuring personality functioning with the 12-item version of the OPD-Structure Questionnaire (OPD-SQS): reliability, factor structure, validity, and measurement invariance in the general population

Background

The assessment of personality functioning is at the core of current dimensional models of personality disorders. A variety of measures from different clinical and research traditions aim to assess basic psychological capacities regarding the self and others. While some instruments have shown reliability and validity in clinical or other selected samples, much less is known about their performance in the general population.

Methods

In three samples representative of the German adult population with a total of 7,256 participants, levels of personality functioning were measured with the short 12-item version of the Operationalized Psychodynamic Diagnosis - Structure Questionnaire (OPD-SQS). We addressed questions of factor structure, reliability, validity, factorial invariance, and provide norm values.

Results

Confirmatory factor analysis indicated a satisfactory to good model fit. OPD-SQS models were mostly unaffected by variables such as gender, age, or measurement time. As expected, personality functioning was associated with general psychopathology as well as indices of occupational functioning.

Conclusion

The OPD-SQS is a viable measure to assess personality functioning in the general population.

Level of Structural Integration and Its Association with Intersession Experiences and Outcomes: A Pilot Study

The level of structural integration (LSI), a psychodynamic/psychoanalytic concept originally developed by the Operationalized Psychodynamic Diagnosis (OPD), provides a promising empirical approach that is recognized beyond the boundaries of psychoanalysis and is highly relevant for therapy and research. The aim of our study was to investigate the intersession experiences of patients in psychotherapy with different levels of structural integration. The sample consisted of 69 inpatients who were undergoing psychotherapeutic treatment. The patients were asked to complete the German version of the Intersession Experience Questionnaire (IEQ), the short version of the OPD Structure Questionnaire (OPD-SQS) and the Brief-Symptom Inventory (BSI). LSI is associated with the situations, contents and negative emotions in the intersession experiences of patients, as well as their symptom distress over the course of therapy. Furthermore, the level of structural integration is a significant predictor of outcomes. Patients with different LSI had different intersession experiences.

Erstellung und Validierung einer Kurzversion des Fragebogens zur Erfassung aversiver und protektiver Kindheitserfahrung (APK-18)

Zusammenfassung. Die Erfassung von Kindheitserfahrungen stellt einen wichtigen Baustein für Verständnis und Behandlung psychischer Belastungen im Erwachsenenalter dar. Dabei kommt der Erfassung protektiver Kindheitserfahrungen neben etablierten aversiven Erlebnissen eine wachsende Bedeutung zu. Ziel der vorliegenden Studie ist die Erstellung einer validen, reliablen und zeitökonomischen Kurzform des Fragebogens zur Erfassung aversiver und protektiver Kindheitserfahrungen (APK). Mithilfe des Ant-Colony Optimization (ACO) Algorithmus wurden an einer klinisch-psychotherapeutischen Stichprobe ( n = 701) aus den 59 Items der Langversion ein Set von 18 Items identifiziert und an einer nicht-klinischen Stichprobe ( n = 643) validiert. Die Kurzversion (APK-18) zeigte gute Reliabilität und Validität und unterschied anhand latenter Mittelwertunterschiede zuverlässig zwischen klinischen und nicht-klinischen Teilnehmenden. Einschränkungen bezüglich der Reliabilität ergaben sich bei 2 der insgesamt 8 Sub-Skalen, „Sonstige traumatische Ereignisse“ und „Trennungserfahrungen“. Mit der Kurzversion APK–18 liegt ein ökonomisches und valides Messinstrument vor, welches in klinische Routineerhebungen integriert werden kann.
