The Personality Inventory for DSM-5 – Short Form (PID-5-SF) is a 100-item self-report measure designed to assess maladaptive personality traits. It measures 25 personality facets as well as traditional personality disorders. The scale is accompanied by the Personality Inventory for DSM-5 – Adaptive, which selectively administers items most likely to provide clinically meaningful information.
The Personality Inventory for DSM-5 – Short Form (PID-5-SF) is a 100-item self-report measure developed by Maples and colleagues (2015) as a shorter version of the original 220-item PID-5 (Krueger et al., 2012). It assesses 25 facets of maladaptive personality functioning, with each facet measured by four items.
Example PID-5-SF Item
The PID-5-SF serves a dual purpose: (a) measuring an empirically-derived five-factor model of maladaptive personality traits; and (b) providing a dimensional approach to assessing the specific personality disorder types described in the Diagnostic and Statistical Manual of Mental Disorders (DSM), as operationalised through the Alternative Model for Personality Disorders (AMPD) in Section III of the DSM-5-TR, in contrast to the categorical approach in Section II. This dual framework allows clinicians to assess and understand personality dysfunction both dimensionally and in relation to diagnostic categories.
The PID-5-SF is organised around five broad trait domains of personality dysfunction, with each domain primarily defined by three core facets (totalling 15 “primary” facets):
The remaining 10 facets (Attention Seeking, Callousness, Depressivity, Hostility, Perseveration, Restricted Affectivity, Rigid Perfectionism, Risk Taking, Submissiveness, and Suspiciousness) also contribute to the five domains, but often with more complex associations, including significant relationships with multiple domains. For example, Hostility relates to high levels of both Negative Affectivity and Antagonism, while Restricted Affectivity relates to both increased Detachment and decreased emotional expressiveness (the opposite of Negative Affectivity).
The PID-5-SF also generates scores for the specific personality disorder types described in the DSM (including Antisocial Personality Disorder with Psychopathic Features specifier). These AMPD composite scores represent specific configurations of facets that correspond to traditional personality disorder categories:
For clinicians, the PID-5-SF offers several distinct advantages, particularly in comprehensive assessment of maladaptive personality traits and differential diagnosis. It bridges the gap between categorical, diagnostic approaches and dimensional approaches to personality assessment, aligning with the evolving conceptualisation of personality disorders in modern clinical practice. The PID-5-SF aids in assessment, case conceptualisation, treatment planning, and intervention evaluation. As an assessment tool, it helps to identify specific patterns of personality dysfunction that may underlie presenting symptoms (relevant to Diagnostic Criterion B of the AMPD), facilitating a more nuanced understanding of maladaptive personality trait-related difficulties even when full diagnostic criteria for personality disorders are not met. Note that the PID-5-SF does not map onto the DSM-5-TR Section II’s categorical model of personality disorders, which is still relied upon in many clinical settings for diagnosis and reporting.
The Personality Inventory for DSM-5 – Adaptive (PID-5-A) is an adaptive version of the PID-5–SF. The PID-5-A was developed by NovoPsych to reduce respondent burden and make comprehensive personality assessment more feasible in time-constrained clinical settings. The adaptive algorithm stops administering items when early responses indicate that further items are unlikely to provide additional clinically relevant information, while preserving complete assessment for potential or actual trait elevations. This reduces the number of items administered by 34%, on average, without compromising the identification of clinically relevant maladaptive personality trait levels.
The PID-5-A addresses the longstanding tension between comprehensive assessment and respondent burden by administering fewer items without compromising the identification of elevated maladaptive personality trait levels. The reduced number of items administered and completion time decrease respondent burden, and the time savings also improve the feasibility of incorporating comprehensive personality assessment within routine clinical practice.
Scoring and interpretation of the PID-5-SF involves summing the item responses within each facet and domain to obtain average scores (between 0 and 3). Higher average scores indicate elevated levels of specific personality traits, while average scores indicate relatively lower expression of those traits. The Personality Inventory for DSM-5 – Short Form (PID-5-SF) yields scores for five empirically-derived domains of maladaptive personality functioning, 25 personality facets, and the specific personality disorder types described in the DSM. Higher scores indicate greater presence of maladaptive personality traits.
The PID-5-SF provides scores for five broad domains of maladaptive personality functioning:
The PID-5-SF measures 25 facets of maladaptive personality, with each facet assessed by four items. These facets provide a more nuanced understanding of maladaptive personality functioning than the broader domains.
The PID-5-SF also generates scores for the specific personality disorder types described in the DSM (including Antisocial Personality Disorder with Psychopathic Features specifier). These AMPD composite scores represent specific configurations of facets that correspond to traditional personality disorder categories:
Responses to individual items are scored from 0 (“Very false or often false”) to 3 (“Very true or often true”). Average scores are calculated for each facet by averaging the four constituent item scores, resulting in average facet scores ranging from 0 to 3. Average domain scores are calculated by averaging the average scores of the three primary facets within each domain, also ranging from 0 to 3. AMPD composite scores are calculated by summing the average scores of constituent facets, with possible score ranges varying depending on the number of constituent facets.
The respondent’s scores are also presented as percentiles based on normative data from a representative sample of adults in the United States (Miller et al., 2022; see also Krueger et al., 2012). The percentiles contextualise the respondent’s scores relative to the general adult population. A score on the 50th percentile represents the typical level for that personality domain, facet, or type in the general adult population, while a score on or above the 84.13rd percentile (1.0 standard deviation above the mean) is considered “Elevated” and a score on or above the 93.32nd percentile (1.5 standard deviations above the mean) is considered “Clinically Significant.” The threshold for clinical significance was established based on statistical grounds, psychometric precedent, and clinical utility, and was further validated using data from over 15,000 mental health treatment-seeking clients assessed on NovoPsych.
On first administration, graphs are presented showing the respondent’s scores as percentiles for:
Scores displayed within the area coloured red meet the threshold for clinical significance and represent the most pronounced deviations from typical personality variations, while scores displayed in the area coloured orange meet the “Elevated” threshold and represent notable but less pronounced deviations.
If administered more than once, longitudinal graphs are presented for the respondent’s scores as percentiles, enabling clinicians to monitor changes in maladaptive personality traits over time and in response to treatment.
The Personality Inventory for DSM-5 – Short Form (PID-5-SF) has demonstrated strong psychometric properties across multiple studies, establishing it as a reliable and valid measure of maladaptive personality traits that performs comparably to the original 220-item PID-5.
The PID-5-SF has shown excellent internal consistency across different samples. Maples and colleagues (2015) reported Cronbach’s alpha coefficients ranging from .89 to .91 for the five domain scales and from .74 to .88 for the 25 facet scales in a derivation sample of university students and mental health treatment-seeking adults in the community (n = 1,417). In their validation sample of mental health treatment-seeking adults (n = 109), the reliability remained strong, demonstrating that the abbreviated scales maintain the psychometric integrity of the original PID-5 despite the significant reduction in items.
In an independent evaluation using Norwegian university student samples, Thimm and colleagues (2016) found comparable reliability estimates. In their derivation sample (n = 503), Cronbach’s alpha coefficients ranged from .85 to .91 for domains and from .74 to .88 for facets. Similarly robust results were found in their replication sample (n = 127), with Cronbach’s alpha coefficients ranging from .87 to .91 for domains and from .67 to .91 for facets. Across both studies, the mean inter-item correlations for domains (approximately .41) and facets (.54-.66) fell within the optimal range, indicating good internal consistency without excessive item redundancy.
These findings consistently demonstrate that the PID-5-SF maintains excellent reliability despite using fewer items per scale than the original PID-5, supporting its use as an efficient alternative for assessing maladaptive personality functioning.
Factor analytic studies have consistently supported the five-factor structure of the PID-5-SF, with factor congruence coefficients between the short (PID-5-SF) and original (PID-5) forms ranging from .93 to .99 (Maples et al., 2015). The five-factor structure has been replicated across different samples, including in Norway (Thimm et al., 2016), demonstrating the robustness of the measure’s structural validity.
Confirmatory factor analyses of the individual facet scales have generally shown good model fit, supporting the unidimensionality of each facet despite the reduced number of items. Thimm and colleagues (2016) reported comparative fit indices values ranging from .95 to 1.00 for the facet scales, indicating excellent fit.
The PID-5-SF demonstrates excellent convergent validity with the original PID-5. Maples and colleagues (2015) reported convergent correlations ranging from .96 to .98 for domains and from .89 to 1.00 for facets, with mean convergent correlations of .97 and .94, respectively. These exceptionally high correlations indicate that the shortened scales capture essentially the same constructs as the original, longer scales.
Both the original PID-5 and the PID-5-SF show expected relationships with the five-factor model of personality (FFM). Negative Affectivity correlates positively with Neuroticism, Detachment correlates negatively with Extraversion, Antagonism correlates negatively with Agreeableness, Disinhibition correlates negatively with Conscientiousness, and Psychoticism shows more complex relationships across multiple FFM domains (Thimm et al., 2016).
The PID-5-SF domains also demonstrate theoretically consistent relationships with measures of maladaptive personality beliefs. For example, Thimm et al. (2016) found that paranoid beliefs were strongly related to Suspiciousness, antisocial beliefs to Callousness and Deceitfulness, and avoidant beliefs to Anxiousness and Withdrawal.
Discriminant validity of the PID-5-SF is supported by the pattern of inter-domain correlations, which is almost identical to that of the original PID-5 (intraclass correlation of .98; Maples et al., 2015). The domains show moderate intercorrelations, reflecting the fact that personality dysfunction tends to manifest across multiple domains while still representing distinct constructs.
The PID-5-SF demonstrates strong criterion validity in relation to clinical outcomes and DSM personality disorder diagnoses. Maples and colleagues (2015) found that the criterion validity of the PID-5-SF with interviewer-rated Section II and Section III scores, and internalising and externalising outcomes was nearly identical to that of the original PID-5.
Bach and colleagues (2015) demonstrated the clinical utility of the Alternative Model for DSM Personality Disorders (AMPD), as measured by the PID-5, through detailed case studies, showing how the personality trait profiles can effectively characterise individuals with various personality disorders and inform treatment planning.
Miller and colleagues (2022) provided normative data for the PID-5 domains, facets, and AMPD composites based on a representative sample of U.S. adults (obtained from Krueger et al., 2012). These norms can be used for the interpretation of PID-5-SF scores given the high congruence between the original PID-5 and the PID-5-SF. Miller and colleagues reported scores at 1.0, 1.5, and 2.0 standard deviations above the mean as potential thresholds for meaningful deviations on PID-5-SF scores. After considering statistical significance, psychometric precedent, and clinical utility, NovoPsych selected the 93.32nd percentile (corresponding to 1.5 standard deviations above the mean) as the threshold for clinical significance. This threshold was further validated using data from over 15,000 mental health treatment-seeking clients assessed on NovoPsych (see NovoPsych’s review of the PID-5-SF [Baker et al., 2025]). The 84.13rd percentile (corresponding to 1.0 standard deviation above the mean) was selected as the threshold for identifying deviations that may also be clinically relevant but less pronounced.
The psychometric evidence demonstrates excellent internal consistency for both domain and facet scales, a robust five-factor structure confirmed across multiple samples, and strong convergent validity with both the original PID-5 and related constructs. The PID-5-SF shows appropriate discriminant validity through its pattern of inter-domain correlations and maintains the criterion validity of the original PID-5. Comprehensive normative data further enhances its interpretability. These psychometric properties collectively establish the PID-5-SF as a reliable and valid measure of maladaptive personality traits.
Personality traits exist on a continuum — everyone has them to varying degrees. The PID-5-SF measures maladaptive personality traits that, when elevated, can cause difficulties in relationships, work, and daily life. Having elevated traits doesn’t necessarily mean someone has a personality disorder; rather, it indicates specific patterns of thinking, feeling, and behaving that may be problematic. A personality disorder reflects a specific configuration of elevated maladaptive personality traits together with significant impairment in self-identity and interpersonal functioning. Importantly, the PID-5-SF serves a dual purpose: assessing both the dimensional spectrum of maladaptive personality traits and traditional personality disorder categories.
The PID-5-SF can be used by qualified professionals, such as psychologists, as part of a comprehensive diagnostic assessment process for personality disorders; however, the PID-5-SF should not be solely relied upon for assigning a diagnosis of any personality disorder. It is designed to assess maladaptive personality traits that correspond to the dimensional trait model outlined in the Alternative Model for Personality Disorders (AMPD) in Section III of the DSM-5-TR. Clinicians can use PID-5-SF scores as part of a comprehensive assessment to better understand underlying personality patterns, inform diagnostic impressions, and guide treatment.
The Personality Inventory for DSM-5 – Adaptive (PID-5-A) is an adaptive version of the Personality Inventory for DSM-5 – Short Form (PID-5-SF; Maples et al., 2015). The PID-5-A was developed by NovoPsych to reduce respondent burden and improve the feasibility of comprehensive personality assessment in time-constrained clinical settings. Using an adaptive administration algorithm, item delivery is discontinued when early responses indicate that additional items are unlikely to yield clinically meaningful information, while ensuring full assessment for potential or actual trait elevation. On average, the PID-5-A administers 66 items (versus 100 for the full-length PID-5-SF) and reduces completion time. When the PID-5 is used for screening purposes, the adaptive version is recommended due to its reduced respondent burden without compromising clinical utility. Both versions yield scores for the same domains, facets, and AMPD composites.
Traditionally, personality disorders have been viewed categorically — someone either meets criteria for a disorder or they don’t, as reflected in Section II of the DSM-5-TR. However, research increasingly supports a dimensional approach, recognising that personality pathology exists on a continuum rather than in distinct categories. The Alternative Model for Personality Disorders (AMPD) in Section III represents this shift, conceptualising personality disorders as combinations of impairments in personality functioning and elevations in maladaptive traits. The PID-5-SF aligns with this dimensional approach, measuring the degree to which someone exhibits various personality traits rather than simply determining presence or absence of a disorder. This dimensional perspective better captures the complexity of personality, explains why people with the same diagnosis can present very differently, and helps clinicians tailor treatment to specific trait patterns rather than broad diagnostic labels. Many professionals now view personality disorders as having both categorical and dimensional aspects — while diagnostic thresholds remain useful for communication and treatment planning, understanding the underlying trait dimensions provides richer clinical information.
The five maladaptive personality trait domains assessed by the PID-5-SF can be understood as extreme or problematic variants of the well-known Five Factor, Big Five, or OCEAN model of personality, as measured by the IPIP-NEO-120. Negative Affectivity corresponds to very high Neuroticism, involving intense anxiety, emotional instability, and persistent negative emotions. Detachment represents extremely low Extraversion, characterised by social withdrawal, anhedonia, and emotional coldness. Antagonism reflects very low Agreeableness, including callousness, manipulation, and hostility toward others. Disinhibition corresponds to very low Conscientiousness, involving impulsivity, irresponsibility, and lack of self-control. Psychoticism relates most closely to unusual manifestations of Openness, but captures more severe perceptual and cognitive distortions. These connections demonstrate that maladaptive personality traits represent extremes of normal personality variation rather than entirely separate phenomena.
Self-report measures like the PID-5-SF rely on self-awareness, which can be challenging when assessing personality. Scores might differ from self-perception if someone is comparing themselves to a specific reference group, experiencing current stress that colours self-perception, or has limited insight into how others experience them. Some people minimise difficulties while others are overly self-critical. Discussing results with a mental health professional can help clarify whether scores accurately reflect personality patterns or if other factors are influencing responses.
People can have elevated maladaptive personality traits without significant impairment, especially if they’ve developed effective coping strategies or work in environments that accommodate their traits. For example, someone with elevated Rigid Perfectionism might excel on detail-oriented tasks, or someone with elevated Emotional Lability might thrive in creative fields. The key factor is whether these traits cause distress or interfere with important areas of life. Context matters — traits that are problematic in one setting may be adaptive in another.
While personality traits tend to be relatively stable, they can shift with significant life experiences, therapy, or personal development. The PID-5-SF captures current patterns of traits, which may be influenced by stress, mental health conditions, or recent life events. Some traits, particularly those related to emotional instability and impulsivity, often decrease with age and maturity. While primarily an assessment tool, the PID-5-SF can be used over time to help track whether interventions are helping to reduce problematic trait expressions.
