A new questionnaire, the Operationalised Psychodynamic Diagnosis (OPD) structure axis (OPD-SQ), allows for reliable patient assessment of psychic structure. This tool aids routine clinical use and research by including patient perspectives.
Area of Science:
- Psychology
- Psychiatry
- Clinical Psychology
Background:
- Psychodynamic diagnosis relies heavily on psychic structure assessment.
- Current methods require expert clinical interviews, limiting routine use and patient input.
Purpose of the Study:
- To develop and evaluate the Operationalised Psychodynamic Diagnosis (OPD) structure axis questionnaire (OPD-SQ).
- To enable reliable and valid assessment of psychic structure from the patient's perspective.
Main Methods:
- Development and evaluation of the OPD-SQ questionnaire.
- Administration to clinical and non-clinical samples (N = 1,112).
- Analysis of internal consistency, sample differences, and correlations with personality measures.
Main Results:
- The OPD-SQ demonstrated good internal consistency across all sub-scales.
- Expected differences were found between clinical and non-clinical samples, and in patients with/without personality disorders.
- Correlations with attachment security and neuroticism were observed, with minimal age/gender effects.
Conclusions:
- The OPD-SQ is a reliable and valid tool for assessing psychic structure.
- It facilitates broader clinical routine use and research by incorporating patient perspectives.
- The questionnaire is a valuable addition to psychodynamic assessment.
