Summary
A new short form of the DSM-5 Level of Personality Functioning Questionnaire (DLOPFQ) was developed. This brief measure accurately assesses personality functioning, offering a valuable tool for clinical and research settings.
Area of Science:
- Psychiatry and Psychology
- Mental Health Assessment
- Personality Disorders
Background:
- The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) introduced the Alternative DSM-5 Model for Personality Disorders (AMPD).
- Criterion A of the AMPD defines level of personality functioning (LOPF) through self and interpersonal functioning.
Purpose of the Study:
- To describe the development of a short form of the DSM-5 Level of Personality Functioning Questionnaire (DLOPFQ).
- To create a brief, reliable, and valid measure of LOPF as conceptualized by the AMPD.
Main Methods:
- A sample of 1,279 participants from diverse settings completed the full DLOPFQ.
- Exploratory and confirmatory factor analyses were used to select items and validate the short form.
- Internal consistency, convergent validity, and factor structure were assessed.
Main Results:
- The DLOPFQ Short Form demonstrated good internal consistency.
- Short-form subscales correlated strongly with full-form subscales and related constructs.
- Confirmatory factor analysis supported a second-order factor model for LOPF.
Conclusions:
- The DLOPFQ Short Form provides a brief and effective assessment of personality functioning.
- This measure is suitable for use in clinical and research contexts.
- Future research should explore further refinements and applications of the DLOPFQ Short Form.

25.1K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.

Personal identity is the deeply felt sense of self that individuals cultivate over time, intricately woven from intrinsic qualities they consider essential to their existence—qualities such as morality, intelligence, and friendliness. These attributes serve as vital internal benchmarks, guiding individuals in evaluating whether their actions resonate with their true selves.When personal identity takes center stage in one's life, individuals often emphasize their distinctiveness,...

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
