Associations of Reversal Learning Performance With Personality Disorder Profile and Drug Abuse History in a Sample of Prison Inmates.

Prison inmate samples present a high prevalence of impulsivity- and compulsivity-related behavioral problems. The Probabilistic Reversal Learning Task (PRLT) is a useful tool to assess decision-making, and we explore its associations with inmates' personality disorder (antisocial personality disorder, APD; obsessive-compulsive personality disorder, OCPD; or both) and history of drug abuse. Mixed-effects methods were used to model acquisition and reacquisition curves across PRLT, in a sample of 275 prison inmates diagnosed with OCPD, APD, or both. Two aspects were assessed: general discrimination learning and decision-making inflexibility. Participants with a mixed personality disorder profile showed a clear pattern of decisional inflexibility. A history of drug abuse was associated with a general poorer performance but not with decision-making inflexibility. Inability to adapt to changing contingencies, and thus to adverse consequences of previously rewarded choices, was not linked to compulsivity, as hypothesized to be present in OCPD and substance use disorders, but to the mixed APD/OCPD profile.

Impulsivity in antisocial personality disorder and obsessive-compulsive personality disorder in prison population

This study examined impulsivity in antisocial personality disorder (ASPD) and obsessive-compulsive personality disorder (OCPD) in the context of criminal offending. Participants completed the Demographic, Criminal, and Institutional Behavior Interview, the International Personality Disorder Examination, the Symptom Checklist-90-Revised, and the Impulsive Behavior Scale, that the APD and OCPD groups can commit the same crimes (against people and against objects). The results revealed that ASPD and OCPD groups can commit the same crimes (against human and against objects), although they differ in terms of impulsivity [Negative Urgency (UN), Sensation Seeking (BS) and Positive Urgency (UP)], with the OCPD group scoring lower on these dimensions. In the ASPD group, those who had committed crimes against human scored higher in UN, BS and UP than those who had committed crimes against objects. In the OCPD group, those who had committed crimes against human scored higher on UN and lower on BS and UP than those who had committed crimes against objects. The importance of analyzing personality disorder profiles for a better understanding of criminal behavior is emphasized.

Personality traits and change in depression status at 18 months: Findings from a British Psychiatric Morbidity Survey

BackgroundDepression is a common mental disorder, yet it shows low remission rates. The available evidence on personality traits as factors associated with the course of depression has common methodological limitations. Identifying personality traits linked with depression can improve understanding of the course of illness. Therefore, we aimed to investigate personality traits that are associated with the course of depression over 18 months. Methodslongitudinal data of 2366 Adult Psychiatric Morbidity Survey respondents were analysed. Assessments were applied at two-time points (baseline) and follow-up (about 18 months later). We assessed the total score on the screening questionnaire from the Structured Clinical Interview (SCID-II) for the dependent, obsessive-compulsive, and borderline personalities. Depression was measured using the revised Clinical Interview Schedule (CIS-R) version. ResultsAn increase of one score on the borderline personality scale at baseline increased the odds of experiencing persistent depression by 1.50 times (OR = 1.50, 95 % CI [1.22–1.86]), depression onset by 1.30 times (OR = 1.30, 95 % CI [1.14–1.50]), and recovery by 1.52 times (OR = 1.52, 95 % CI [1.35–1.70]), comparing to no depression group. Elevated scores of dependent personality traits significantly predicted depression persistence (OR = 1.95, 95 % CI [1.52–2.49]). An increase of one score on the obsessive-compulsive personality scale increases the odds of depression onset by 1.21 times (OR = 1.21, 95 % CI [1.04–1.39]). LimitationsThe APMS survey defined depression statuses in a limited sense, which may affect the generalisability of these results. ConclusionThe present study confirms previous findings and contributes evidence suggesting that personality dysfunctions worsen depression outcomes.

Association between pathogenic beliefs and personality disorders

Background and objectivesPersonality disorders are significant entities in the field of psychiatry and serve as predisposing factors for Axis I clinical disorder. The Treatment of choice is psychotherapy, and one specific approach is Control Mastery Therapy, which emphasizes addressing Pathogenic beliefs (PB). This study aimed to investigate whether there is a relationship between PB and specific personality disorders and whether these beliefs align with the core features specified in the Diagnostic and Statistical Manual of Mental Disorders (DSM) for that personality disorder. Materials and methodsThis study employed a retrospective cross-sectional design and included 319 participants, comprising individuals receiving treatment at the Psychotherapy Clinic at Maharaj Nakorn Chiang Mai Hospital, Faculty of Medicine, Chiang Mai University between 2007 and 2023. All participants were assessed and completed the Structured Clinical Interview for DSM-IV Axis II - Personality Disorders Questionnaire (SCID-II-PQ), Pathogenic Beliefs Scale, and Outcome-Inventory (depression). A generalized linear model (binary logistic regression) was employed, and the predictors included personality disorders. The outcome was the pathogenic belief, and covariates encompassed age, sex, education, clinical diagnosis, and depression score. A sensitivity analysis was conducted to examine the effect on the model when outliers of depressive scores were present. ResultsAfter adjusting for depression, ten personality disorders were found to predict 16 pathogenic beliefs out of the 27 outcomes examined. Notably, histrionic and obsessive-compulsive personality disorders showed no association with specific pathogenic beliefs. Furthermore, certain pathogenic beliefs were predicted by multiple personality disorders, while conversely, some personality disorders were associated with multiple pathogenic beliefs as well. Sensitivity analysis revealed that outliers influenced the relationships between certain disorders and pathogenic beliefs, particularly those with small effect sizes. ConclusionsThe profound impact of pathogenic beliefs intertwined with personality disorders, particularly influenced by childhood trauma and evident in Cluster B and schizotypal disorders, underscores the critical need for targeted psychotherapeutic interventions. Addressing these beliefs directly is key to enhancing treatment efficacy and patient outcomes. Pathogenic belief should be elicited in clinical settings regardless of personality disorder, especially those who experienced depression. Moving forward, rigorous research is imperative to validate and refine therapeutic approaches aimed at reshaping pathogenic beliefs, ensuring they become pivotal in transforming clinical practice and advancing mental health care.

Psychological and Psychiatric Characteristics of People with Keratoconus

Background and Objectives: There are many reports in the literature on the co-occurrence of somatic diseases and psychiatric disorders. Relatively few have addressed the co-occurrence of corneal cone with anxiety, depression, or personality disorders. Materials and Methods: 99 patients with keratoconus (study group) and 92 patients without keratoconus (control group) participated in the entire study, which was conducted in 2015 and 2020–2023. The Hamilton Depression Rating Scale (HDRS) and Beck’s Depression Inventory (BDI) were used to assess depressive symptoms, the State-Trait Anxiety Inventory (STAI) to assess anxiety symptoms, and the DSM-IV Personality Disorder Inventory (IBZO-DSM-IV) to identify personality disorders. Results: In the study group, the severity of depressive and anxiety symptoms correlated with all types of personality disorders. In the control group, these symptoms did not correlate with antisocial and narcissistic personalities. In the comparative analysis, there were more patients with antisocial, schizotypal, obsessive compulsive, schizoid, paranoid, and dependent personality traits in the study group. Conclusions: Patients with keratoconus have increased expressions of antisocial personality traits, but no differences in anxiety and depression symptoms were evident. Further research is needed among patients diagnosed with keratoconus in the short term.

AB069. Type of personality and cancer-related pain in central nervous system (CNS) tumor patients: a cross-sectional study.

Pain is the most common complaint experienced by central nervous system (CNS) tumor patients. Pain, especially cancer pain, involves the whole aspect of a person, such as personality, cognition, and behavior. Personality characteristics play an important role in how a person perceives pain rate and deals with painful situation. This study aimed to describe types of personality and investigate relationship between types of personality and cancer-related pain in CNS patients. This study was conducted at Cipto Mangunkusumo General Hospital from January to December 2023, that was determined by random sampling. The analysis included a total of 99 subjects from inpatient settings. In depth interview was used to assess type of personality and Numeric Rating Scale (NRS) was used to assess intensity of pain. Data analyses were carried out using the Chi-squared and Fisher's exact test to assess the relationship between types of personality and cancer-related pain in CNS patients. There were 99 subjects with mean age of 48.37±12.96 years, mostly women (60.6%). The results showed that in patients with CNS tumor, the most common neurological deficit was cancer pain (93.9%), consisting of no-mild pain (30.3%) and moderate-severe pain (69.7%). The prevalence of narcissistic personality was 73.7%, followed by histrionic personality 15.2%, and other personality (11.1%) such as borderline, obsessive-compulsive, and avoidant personality. Narcissistic personality traits were found in 48.5% of patients with moderate-severe pain. However, bivariate analysis showed that there was no significant relationship between types of personality and intensity of pain in CNS tumor patients (P=0.60). Although there was no significant relationship, cluster B personality (narcissistic, histrionic, and borderline) was found in a large percentage of CNS tumor patients. Research findings showed that intensity of pain was caused by biological components of pain and may be influenced by the patient's perception of pain itself, not solely due to personality. Therefore, it's important for health workers to pay attention and give optimal management to every patient's pain complaint, and not to ignore or minimize it. Psychiatrists can be involved by giving psychotherapy so that patients can deal with their pain in a more adaptive way.

Exploring the Nexus: Personality Disorders and Their Impact on Violent Extremism, Radicalism, and Activism.

The escalating global concerns surrounding radicalization and violent extremism necessitate a comprehensive understanding and explanation. Identifying the risk factors associated with radicalism and violent extremism is critical to the development of risk assessment, prevention, and intervention strategies. It is imperative to distinguish these risks from civic responsibilities (i.e., activism) to safeguard individual rights. This study aims to examine the association between well-established risk factors for violence-personality disorder symptoms-and violent extremist attitudes, radicalism, and activism. Findings indicate that antisocial personality disorder symptoms were linked to violent extremist attitudes and radicalism, whereas obsessive-compulsive disorder symptoms were related to activism. This suggests that obsessive-compulsive personality disorder may signify a readiness for legal and nonviolent political action; in contrast, antisocial personality disorder symptoms signify a readiness for extremist violence and illegal political action.

Evaluating the Impact of Obsessive-Compulsive Symptoms and Personality Types on Perinatal Depressive Symptoms.

Perinatal depression (PPD) presents a significant public health concern, often influenced by psychological and personality factors. This study investigated the impact of personality traits, particularly neuroticism, and obsessive-compulsive disorder (OCD) symptoms on the severity of PPD. The primary aim was to quantify the contributions of these factors to the risk and severity of PPD to enhance early intervention strategies. A total of 47 pregnant women with depressive symptoms per DSM-5 criteria at "Pius Brinzeu" County Emergency Hospital in Timisoara, Romania, were enrolled in this cross-sectional study, as well as 49 women without depressive symptoms as controls. Personality traits were assessed using the NEO Five-Factor Inventory (NEO-FFI), and OCD symptoms were measured using the Obsessive-Compulsive Inventory (OCI). Depression severity was evaluated using the Edinburgh Postnatal Depression Scale (EPDS). This set of questionnaires were administered antepartum and postpartum. The logistic regression analysis highlighted neuroticism as a significant predictor of PPD severity, with an increase in neuroticism associated with a higher risk of PPD (coefficient = 0.24, p < 0.001). Conversely, openness showed a protective effect (coefficient = -0.13, p = 0.009). Higher OCD symptomatology, particularly ordering and hoarding, were linked with increased depression scores. Specifically, the total OCI score significantly predicted the EPDS score (coefficient = 0.03, p = 0.003). Furthermore, significant increases in EPDS anxiety and depression scores were observed in the perinatal period, indicating worsening of symptoms (anxiety coefficient = 0.51; p < 0.001). The findings suggest that personality traits like neuroticism and OCD symptoms significantly contribute to the severity of PPD. Interventions targeting these specific traits could potentially mitigate the risk and severity of perinatal depression, underscoring the need for personalized treatment plans that consider these psychological dimensions.

Child Abuse and Neglect and Obsessive–Compulsive Personality Traits: Effects of Attachment, Intolerance of Uncertainty, and Metacognition

AbstractChild Abuse and Neglect (CAN) is extensively implicated as a risk factor preceding the development of Obsessive–Compulsive Personality Traits (OCPT). Nevertheless, the majority of individuals with a history of CAN do not go on to develop OCPT. To date, little research has investigated potential model networks that may help contribute to explaining why CAN sometimes leads to OCPT and not at other times. Thus, this study aimed to investigate whether attachment-anxiety, intolerance of uncertainty, and metacognition have indirect effects in the association between CAN and OCPT in various network models. Undergraduate psychology students (N = 291) participated in an anonymous 30-min online survey consisting of a series of self-report questionnaires regarding child abuse and neglect, attachment, intolerance of uncertainty, metacognition, OCPT, and depression. Bootstrapped serial mediation revealed attachment-anxiety and intolerance of uncertainty had a serial-mediation effect in the association between CAN and OCPT. Serial mediation was not found for metacognition and attachment-anxiety. However, metacognition alone mediated between child emotional abuse and OCPT. These findings expand our currently limited knowledge regarding the etiology of OCPT and suggest that attachment-anxiety, intolerance of uncertainty, and metacognition may be important contributors for understanding the development of OCPT following CAN exposure. The potential clinical utility for both assessment and treatment are discussed.

Acceptance and Commitment Therapy as a Conceptual Treatment Model for Obsessive-Compulsive Personality Disorder

Acceptance and commitment therapy (ACT) has demonstrated efficacy in thousands of clinical trials for eating disorders, depression, anxiety, personality disorders, and more. However, ACT has not established efficacy as a treatment for obsessive compulsive personality disorder (OCPD) in a clinical trial. The prevalence of OCPD is one of the highest among personality disorders, yet there is a dearth of research regarding empirically supported treatments and the disorder in general. Aspects of OCPD, including perfectionism, mood intolerance, experiential avoidance, and impaired psychosocial functioning, make it particularly suitable for research involving ACT, which aims to increase psychological flexibility. The purpose of this paper is to elucidate a conceptual model for the treatment of OCPD using ACT. Specific strategies and techniques will be discussed. Future research avenues include exploring ACT as a viable treatment for OCPD, as well as the constructs of experiential avoidance and psychological flexibility related to OCPD functioning.

Breast Cancer and Its Impact on Individual Personality Through a Dimensional Perspective: A Literature Review.

Psychiatric pathology stands out in contemporary society not only as independentbut also through its association with other medical comorbidities such as neoplastic diseases. Specialized literature confirms over time the coexistence of these diseases. There is a tendency to develop various psychiatric manifestations such as mood disorders and somatoform disorders, as well as decompensation of underlying existing psychiatric pathologies (anxiety disorders and psychotic disorders) or personality disorders (a good example is the exacerbation of anxiety in obsessive-compulsive personality disorder). Breast cancer, like any disabling disease, affects the person's psyche and behaviors as a whole. It is scientifically proven that mental balance influences the quality of life of patients and also the evolution and prognosis of the disease, psychological processes being able to modulate the activity ofthe tumor process. It is necessary to expand clinical practice and research beyond the simple evaluation of symptoms, and the goal of treatment should not only be to reduce symptomsbut also to improve in terms of both physically and mentallythe quality of life of cancer patients.

Adverse Childhood Experiences and Obsessive-Compulsive Personality Traits: Mediating Effects of Attachment and Metacognition

Adverse Childhood Experiences and Obsessive-Compulsive Personality Traits: Mediating Effects of Attachment and Metacognition

Work addiction and personality organization: Results from a representative, three-wave longitudinal study

Background: Several studies have explored the relationship between personality and work addiction, suggesting that individuals with certain mental disorders, including personality disorders such as obsessive-compulsive personality disorder (OCPD), may be more prone to work addiction. However, the characterization of personality organization (PO) among workaholics and its contribution to the persistence of work addiction remains unclear. Methods: In this longitudinal study of a representative sample of young adults (N = 1748), we applied the Bergen Work Addiction Scale and the Inventory of Personality Organization. Results: We found significant correlations between work addiction and identity diffusion, primitive psychological defenses, reality testing, and overall personality disorganization across three waves. A latent class growth analysis revealed three profiles: no work addiction, increasing work addiction, and constant moderate work addiction. Multinomial logistic regression analysis indicated that higher levels of personality disorganization in wave 1 and increases in personality disorganization between waves 1 and 3 were associated with higher odds of belonging to the increasing work addiction group. Similarly, higher overall personality disorganization in wave 1 was associated with higher odds of belonging to the constant moderate work addiction group. Conclusion: These findings suggest that individuals with chronic work addiction have lower levels of PO, and PO declines as work addiction persists. Screenings for work addiction are recommended to prevent potential mental health issues. Future research should explore the influence of workplace characteristics and work motivations on the association between work addiction and personality disorders.

Analysis of writing in personality disorders in prison population

AbstractWriting involves the activation of different processing modes than reading comprehension, and therefore the level of activation varies depending on the moment and the task.Objectivesto analyze the profiles in terms of the proposed coding from the PROESC in terms of personality disorders [Antisocial Personality Disorder (ASPD) with drugs possession and consumption crimes (DPCC) and Obsessive-Compulsive Personality Disorder (OCPD)] with gender violence crimes (GVC) in the prisoners.DesignThe sample was composed of 194 men. The participants were divided into two groups. Group 1 (ASPD; DPCC) consisted of 81 men, and Group 2 (OCPD; GVC) consisted of 113 men.Main outcome measuresThey completed the Demographic, Offense, and Behavioral Interview in Institutions, the International Personality Disorders Examination (IPDE), and Writing Processes Evaluation Battery (PROESC).ResultsGroup 2 made more mistake than Group 1 in narratives tasks.ConclusionParticipants know phoneme-grapheme correspondence rules, language disturbances of a reiterative and persistent nature may appear in those who show compulsive behavior.

Clinical features of auto-aggressive behavior in borderline personality disorder: a review of current research

Borderline personality disorder (BPD) is a common psychiatric disorder characterized by severe auto-aggression (AA) in the form of suicide attempts (SA) and non-suicidal self-injury (NSSI). The purpose of this review was to describe the current knowledge about the clinical features of self-harming behavior in borderline personality disorder. Materials and methods: The eLibrary, PubMed, CNKI, and Google Scholar databases were searched for articles on the relevant search query for the last 11 years. As a result, 28 articles were selected and summarized (a total of 7,284 BPD patients and 134 controls were included). Results: Suicidal attempts occur in 75 % of BPD patients, and NSSIs — in 90 %. AA behavior varies with age: adolescents tend to NSSIs, while adults more often undertake SAs. Depending on the type of clinical dynamics, AA in BPD may be impulsive, demonstrative, associated with comorbid addiction, or occur in the context of depersonalization. Among BPD symptoms, feelings of chronic emptiness, avoidance of abandonment, emotional instability, and identity disturbance are most commonly associated with auto-aggression. Risk factors for self-harming behavior in BPD include traumatic childhood events, especially physical and sexual abuse, and stress caused by microsocial conflict. Men with BPD and AA more often have comorbid narcissistic, antisocial, paranoid, and schizotypal personality disorders, as well as substance use disorders. Women with borderline personality disorder and AA tend to suffer more from addictive and obsessive-compulsive personality disorders, as well as eating disorders, particularly bulimia nervosa. In conclusion, self-harming behavior in BPD has many clinical features and can manifest in different forms. It is always necessary to study the predominant clinical manifestations, risk factors, and comorbid disorders to be able to assess the severity of AA.

Recent insights in the correlation between social media use, personality traits and exercise addiction: a literature review.

The excessive involvement in physical activity without stopping in between sessions despite injuries, the continuous thinking to exercise feeling insane thoughts and experiencing withdrawal symptoms are all characteristics of the Exercise Addiction (EA), an addictive behavior. While the primary exercise addiction is directly caused by compulsive exercise, many studies highlighted the relationship between Eating Disorders (ED) and EA, defining the secondary EA. The correlation between EA, social media use (SMU) and other individual traits remains a relatively underexplored domain. Therefore, this review aimed to examine the latest evidence on the relationship between EA, SMU, and some personality traits such as perfectionism and body image. Electronic databases including PubMed, Medline, PsycARTICLES, Embase, Web of Science were searched from January 2019 to October 2023, following the PRISMA guidelines. A total of 15 articles were examined and consolidated in this review. EA was found to be related to different individual traits such perfectionism, body dissatisfaction, depression, obsessive-compulsive personality disorders. While controversial results were found regarding the relationship between EA and SMU. The interaction between mental health, exercise addiction and social media use is complex. Excessive engagement in these latter may result in negative mental health consequences despite their potential benefits. Understanding individual differences and developing effective interventions is crucial to promoting healthy habits and mitigating the EA risks, ultimately enhancing mental well-being. Further research should focus on the identification of risks and protective factors with the eventual aim of developing and implementing effective prevention strategies.

Complex emotional needs, overcontrol and death by suicide in older adults

Globally, older people are frequently at consistently greater risk of dying by suicide than those belonging to any other age group. In countries that report low or moderate rates of suicide in older people, under recognition, under reporting, and under responsiveness may be factors that impact the statistics collected. In countries like the UK, where suicide rates in older people have fallen in line with the national average, suicide in older people occurs ambiguously, may be hidden, or not considered a deliberate act. The introduction of specialist older adult teams and legal restrictions around access to firearms, has likely had some positive impact on the reduction in suicide rate in some older people since the 1980s in the UK. However, these factors may also mean that suicide in older people occurs in individuals who do not access mental health services, or who now use methods that do not appear to be deliberate attempts to die. Psycho-social differences in suicidal older adults are outlined. Older people with complex emotional needs are at greater risk of death by suicide, if they have been given a diagnosis of ‘avoidant’ or ‘obsessive compulsive personality disorder’. It is suggested that ‘overcontrol’ is an underlying psychological need that greatly increases the risk of death by suicide in older people. Identification and treatment of overcontrol is briefly discussed.

Positive Psychology and Mental Health: Solving Problems of Positive Psychology from A New Perspective

Positive psychology tries to help people find happiness, hope, and life satisfaction within people’s lives. However, the approach of positive psychology might be inadequate. To reach all the positive sides, there need to be more negative sides to work with positive psychology because people may not have an accurate understanding of many mental disorders like obsessive-compulsive disorders or personality disorders. Telling them how problematic these mental disorders are might seem negative, but it will help people to have a better understanding of their own mental health. Forming the correct view of mental disorders will reduce stigma and help people with mental disorders reach out for help. Another problem with positive psychology is that many services related to this approach are driven by money, and the intentions might not be helpful for people who want to improve themselves. Possible causes of these problems might be related to the heavy money-related ideas led by Seligman, who is the most famous scientist in the area of positive psychology. Possible solutions might be related more to negative aspects of life in general because learning how to stay peaceful and happy during negative situations might be the only way to define true happiness. Based on the second wave of positive psychology, more attention is still needed to solve these problems by noticing how useful negative aspects of life are.

Romantic relationship obsessive-compulsive doubts, perfectionism, and DSM-5 personality traits in LGB people: a comparison with heterosexual individuals.

Relationship Obsessive-Compulsive Disorder is characterized by the presence of relationship-centered or partner-focused obsessions and compulsions that determine a great sense of doubt toward the partner or the relationship. Personality characteristics, including perfectionism, are involved in the development of Relationship Obsessive-Compulsive Disorder, and could predispose the individual to excessive doubts and preoccupations regarding the "adequacy of the couple" or the physical appearance of one's partner. Evidence from epidemiological research shows that the LGB community can present a high risk and prevalence of obsessive-compulsive symptoms and recent research demonstrated the usefulness of the DSM-5 personality model in understanding the personality of sexual minorities. However, further research is necessary to deepen our knowledge of the relationship between these variables in the LGB community. The aim of the present study was to compare a group of heterosexual individuals to a group of LGB individuals regarding personality traits, perfectionism, and relationship obsessive-compulsive symptoms. A total of 200 participants, 98 in the heterosexual group and 102 in the LGB group, were enrolled in the study and completed a psychological battery comprised of the Obsessive-Compulsive Inventory-Revised, Personality Inventory for DSM-5, Relationship Obsessive-Compulsive Inventory, Partner-Related Obsessive-Compulsive Symptom Inventory, and Multidimensional Perfectionism Scale. The results show that LGB individuals tend to report greater feelings of doubt regarding the partner's love, more negative emotions (Negative Affect) and Antagonism, and greater perfectionism traits compared to heterosexual individuals. These findings underline the necessity to consider the implementation of personalized interventions in clinical practice and the importance of initiating early preventive programs in sexual minority communities.

Prevalence of Obsessive-Compulsive Personality Disorder in Medical Students

Objective: Obsessive-compulsive personality disorder (OCPD) is a cluster C personality disorder, and the most prevalent one. It is mainly characterized by perfectionism and can cause distress and functional impairment in the individual. This study aimed to determine the prevalence of OCPD in medical students, investigate the effect of this disorder on students’ academic performance, and discover any possible related factors.&#x0D; Methods: This cross-sectional observational study consisted of 508 medical students enrolled at the University of Jordan in 2021. It utilized a questionnaire that enquired about their sociodemographic information, academic information, and study habits. It also contained questions about the diagnostic criteria of OCPD from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and questions from the Personality Inventory for the DSM-5 (PID-5) to assess the presence of the rigid perfectionism personality trait.&#x0D; Results: Fifty-one percent of the studied sample either fulfilled the DSM-5 criteria or showed moderate or high expression of rigid perfectionism, according to the PID-5. More than two-thirds of the students able to be diagnosed with OCPD reported being overwhelmed with anxiety and stress at times of exams, and 41.5% stated that they skip sleep before exams even though they have finished studying.&#x0D; Conclusion: The reported prevalence of 51.18% in medical students is ten times the prevalence of OCPD in the general population. There was no association between OCPD and the students’ gender or academic performance. Students affected by OCPD seem to experience overwhelming amounts of stress and may need mental health support in the form of regular check-ups and counseling services.
