The Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-5]; American Psychiatric Association, 2013 ) Section III Alternative Model for Personality Disorders (AMPD) represents a novel approach to the diagnosis of personality disorder (PD). In this model, PD diagnosis requires evaluation of level of impairment in personality functioning (Criterion A) and characterization by pathological traits (Criterion B). Questions about clinical utility, complexity, and difficulty in learning and using the AMPD have been expressed in recent scholarly literature. We examined the learnability, interrater reliability, and clinical utility of the AMPD using a vignette methodology and graduate student raters. Results showed that student clinicians can learn Criterion A of the AMPD to a high level of interrater reliability and agreement with expert ratings. Interrater reliability of the 25 trait facets of the AMPD varied but showed overall acceptable levels of agreement. Examination of severity indexes of PD impairment showed the level of personality functioning (LPF) added information beyond that of global assessment of functioning (GAF). Clinical utility ratings were generally strong. The satisfactory interrater reliability of components of the AMPD indicates the model, including the LPF, is very learnable.
The DSM-5 Section III alternative model for personality disorders (AMPD) is a personality disorder (PD) nosology based on severity of personality dysfunction and pathological traits. We examined the degree to which the personality constructs identified by McAdams and Pals (2006; dispositional traits, characteristic adaptations, narrative identity) and the paradigms of personality assessment described by Wiggins (2003; psychodynamic, interpersonal, personological, multivariate, empirical) are represented within the AMPD. Nine raters expert with the AMPD and personality evaluated elements of Criterion A and the 25 trait facets of Criterion B for presence of type and degree of personality constructs and paradigms, as well as level of inference. Criterion B showed higher rater agreement compared to Criterion A. Criteria A and B reflect different configurations of construct, paradigm, and level of inference. The characteristic adaptation construct and interpersonal paradigm were strongly reflected in both Criteria A and B. The psychodynamic and personological paradigms and the narrative identity construct were highly correlated, and the multivariate, empirical, and dispositional traits variables were highly correlated. Results illustrate differential conceptual emphases as well as areas of overlap with Criteria A and B. This characterization highlights that PD nosology rests on personality theory and suggests implications for integrative PD assessment.
OBJECTIVE: The use of virtual reality (VR) for pain has numerous studies showing effectiveness. However, there has been limited study of its use for chronic pain. METHODOLGY: This pilot study (N=10) investigated the impact of repeated sessions of a VR application for chronic pain on ten subjects. Impact on pain as well as on psychological variables such as depression, anxiety, catastrophizing, and sense of control over pain was assessed. Subjects underwent three twenty minute sessions of the VR application Cool! on a weekly basis using an Oculus Rift or Vive. The impact of the sessions on pain was assessed at four intervals and psychological data captured at two intervals. RESULTS: Results indicate that the VR sessions provided significant pain relief in all treatment sessions with an average of a 66% reduction in pain during the VR session and a 45% reduction in pain immediately after the session. A decrease in pain was reported to last an average of 30 hours after the session. There appeared to be limited if any impact of the VR intervention on chronic pain levels across time. There was no significant impact found for the VR intervention on depression, anxiety, catastrophizing and sense of control over pain. CONCLUSION: Implications for the use of VR on chronic pain conditions are discussed. More frequent VR interventions for chronic pain may be needed to impact pain across time. In addition, VR applications might not be used as an interventional-type in-office treatment as done here but perhaps need to have a skill teaching component or be an application available for in-home and more frequent use.
The construct composition of the Level of Personality Functioning Scale (LPFS; Criterion A) of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition alternative model for personality disorders (American Psychiatric Association, 2013) was examined in a clinical vignette rating study. Multiple indices of level of personality functioning, psychiatric and psychosocial impairment, Criterion B maladaptive personality traits, and conceptually divergent variables (intellectual level, socioeconomic status, and likability) were used to deconstruct the LPFS. Most variables were highly intercorrelated, but partial correlational analyses showed the LPFS possesses meaningful personality construct variance not fully explained by severity of pathological traits, psychiatric and psychosocial impairment, or the conceptually divergent variables. This exploratory study offers initial evidence that the LPFS contains substantive LPF variance beyond PD severity. Results are framed and discussed in terms of the known conceptual and empirical overlap between Criterion A and Criterion B as well as the differing ways a dimension of personality disorder (PD) severity may be interpreted. We propose the LPFS is more than statistical artifact created by empirical covariation but less than a true latent dimension of PD severity. The LPFS may be understood as a methodologically pragmatic but theoretically substantive dimension of PD severity.
Aim: To investigate the 20-year relationship between anxiety, depression and pain medication use. Patients: A total of 521 individuals reporting chronic pain from the National Survey of Midlife Development in the USA (MIDUS) study. Methods: Structural equation modeling of 20-year longitudinal survey data. Results: Over 20 years, a bidirectional relationship between depression and anxiety in individuals with chronic pain was indicated. Pain medication utilization predicted later use at 10 years. Pain medication use was not strongly related to later anxiety; however, heightened anxiety was associated with later use. Conclusion: Depression and anxiety show an extensive long-term bidirectional relationship. While there was little indication of a relationship between pain medication use and later negative mood, anxiety was associated with subsequent pain medication use.
