Description

The Personality Disorder Features Screener (TPDFS-56) is a psychometric instrument designed to identify personality traits that may be associated with personality disorders. The scale provides an initial assessment of personality disorder features and can support further clinical evaluation and diagnostic procedures by mental health professionals.

The instrument focuses on cognitive, emotional, and behavioural characteristics that may be related to maladaptive personality patterns.

Objective

The primary objective of the TPDFS-56 is to provide a rapid and structured method for identifying personality traits associated with personality disorders.

The questionnaire aims to support the diagnostic process by helping mental health professionals recognize potential areas of concern and to provide information useful for the development of targeted therapeutic interventions.

Structure and Content

The TPDFS-56 consists of 56 items assessing different personality traits and behaviours related to personality disorders.

The items examine various psychological characteristics, including patterns of thinking, emotional responses, and behavioural tendencies.

The questions are organized according to characteristics associated with different personality disorder categories, including:

Paranoid personality traits, schizoid personality traits, antisocial personality traits, borderline personality traits, narcissistic personality traits, and dependent personality traits.

Scoring Method

The TPDFS-56 evaluates responses according to the frequency and intensity of specific thoughts and behaviours that may indicate personality disorder features.

The scoring system includes:

The Overall Trait Score, which provides a general indication of the presence of personality disorder-related characteristics.

The Subscale Scores, which allow the evaluation of specific personality disorder-related domains and areas of concern.

Responses are typically rated using a 4- or 5-point Likert scale, indicating the degree to which each statement reflects the individual’s experiences or behaviours.

Data Analysis and Use

The TPDFS-56 can be used in clinical and research settings to examine personality characteristics and identify patterns associated with personality disorders.

The data can support the comparison of personality profiles, the exploration of relationships between personality traits and psychological variables, and the planning of further diagnostic assessment.

Validity and Reliability

Psychometric evaluation of the TPDFS-56 involves examining the reliability and validity of the scale as a screening instrument.

Reliability analysis may include assessment of internal consistency, while validity studies may examine relationships between TPDFS-56 scores and established personality assessment instruments or clinical diagnoses.

Applications

The TPDFS-56 can be applied in clinical psychology, psychiatry, counselling, and psychological research.

It is particularly useful as a screening tool for identifying individuals who may require more detailed personality assessment and clinical evaluation.
