Should cancer pain still be considered a separate category alongside acute pain and chronic non-cancer pain? Reflections on ICD-11

Introduction

Traditionally, cancer pain has often been viewed as an independent third major category in pain medicine alongside acute pain and chronic non-cancer pain. However, the new chronic pain category MG30 in the eleventh version of International Classification of Diseases (ICD-11) includes cancer-related pain as one of its seven subgroups. In light of this, the aim of the paper is to investigate whether the traditional trichotomy should be replaced by a dichotomy between acute pain and chronic pain, cancer-related pain being part of both groups depending on the duration of pain.

Methods

The rationale for viewing cancer pain as a separate category is reviewed.

Results

Cancer being a deadly disease, cancer pain has a life-and-death and existential dimension that is different from non-cancer pain. It seems sensible to believe that this is an additional dimension to the suffering caused by cancer pain, and that clinicians should therefore take this existential dimension into consideration when assessing pain.

Conclusion

Without challenging the place of chronic cancer-related pain under the MG30 heading, it is concluded that while using ICD-11 in the future, pain clinicians should continue being mindful of the fact that the reality of death shapes the experience of cancer pain. The traditional trichotomy is therefore still valid and mirrors the fact that human beings are vulnerable (acute pain), temporal (chronic pain) and mortal (cancer pain).

Assessing complex PTSD and PTSD: validation of the German version of the International Trauma Interview (ITI)

Background: With the introduction of the ICD-11 into clinical practice, the reliable distinction between Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD) becomes paramount. The semi-structured clinician-administered International Trauma Interview (ITI) aims to close this gap in clinical and research settings.Objective: This study investigated the psychometric properties of the German version of the ITI among trauma-exposed clinical samples from Switzerland and Germany.Method: Participants were 143 civilian and 100 military participants, aged M = 40.3 years, of whom 53.5% were male. Indicators of reliability and validity (latent structure, internal reliability, inter-rater agreement, convergent and discriminant validity) were evaluated. Confirmatory factor analysis (CFA) and partial correlation analysis were conducted separately for civilian and military participants.Results: Prevalence of PTSD was 30% (civilian) and 33% (military) and prevalence of CPTSD was 53% (civilians) and 21% (military). Satisfactory internal consistency and inter-rater agreement were found. In the military sample, a parsimonious first-order six-factor model was preferred over a second-order two-factor CFA model of ITI PTSD and Disturbances in Self-Organization (DSO). Model fit was excellent among military participants but no solution was supported among civilian participants. Overall, convergent validity was supported by positive correlations of ITI PTSD and DSO with DSM-5 PTSD. Discriminant validity for PTSD symptoms was confirmed among civilians but low in the military sample.Conclusions: The German ITI has shown potential as a clinician-administered diagnostic tool for assessing ICD-11 PTSD and CPTSD in primary care. However, further exploration of its latent structure and discriminant validity are indicated.

Prolonged grief disorder symptomology in three African countries: A network analysis and comparison

Background

Bereavement is a globally prevalent life stressor, but in some instances, it may be followed by a persistent condition of grief and distress, codified within the 11th edition of the International Classification of Diseases (ICD-11) as prolonged grief disorder (PGD). Network analysis provides a valuable framework for understanding psychological disorders at a nuanced symptom-based level.

Aim

This study novelly explores the network structure of ICD-11 PGD symptomology in a non-Western sample and assesses the replication of this across three African country sub-samples in these data.

Methodology

Network models were estimated using the "Inventory of Complicated Grief-Revised" in a sample of trauma-exposed individuals who experienced bereavement throughout life (N = 1,554) from three African countries (Ghana, n = 290; Kenya, n = 619; Nigeria, n = 645). These networks were statistically evaluated using the network comparison test.

Results

It was found that "Feelings of Loss" and "Difficulty moving on" were the most central symptoms in the combined sample network. These findings were largely consistent for the Ghana and Nigeria sub-samples, however, network structure differences were noted in the Kenya sub-sample.

Conclusion

The identified PGD network highlights particular indicators and associations across three African samples. Implications for the assessment and treatment of PGD in these cultural contexts warrant consideration.

Methodologies and key considerations for implementing the International Classification of Diseases-11th revision morbidity coding: insights from a national pilot study in China

OBJECTIVE

The aim of this study was to disseminate insights from a nationwide pilot of the International Classification of Diseases-11th revision (ICD-11).

MATERIALS AND METHODS

The strategies and methodologies employed to implement the ICD-11 morbidity coding in 59 hospitals in China are described. The key considerations for the ICD-11 implementation were summarized based on feedback obtained from the pilot hospitals. Coding accuracy and Krippendorff's alpha reliability were computed based on the coding results in the ICD-11 exam.

RESULTS

Among the 59 pilot hospitals, 58 integrated ICD-11 Coding Software into their health information management systems and 56 implemented the ICD-11 in morbidity coding, resulting in 3 723 959 diagnoses for 873 425 patients being coded over a 2-month pilot coding phase. The key considerations in the transition to the ICD-11 in morbidity coding encompassed the enrichment of ICD-11 content, refinement of tools, provision of systematic and tailored training, improvement of clinical documentation, promotion of downstream data utilization, and the establishment of a national process and mechanism for implementation. The overall coding accuracy was 82.9% when considering the entire coding field (including postcoordination) and 92.2% when only one stem code was considered. Krippendorff's alpha was 0.792 (95% CI, 0.788-0.796) and 0.799 (95% CI, 0.795-0.803) with and without consideration of the code sequence, respectively.

CONCLUSION

This nationwide pilot study has enhanced national technical readiness for the ICD-11 implementation in morbidity, elucidating key factors warranting careful consideration in future endeavors. The good accuracy and intercoder reliability of the ICD-11 coding achieved following a brief training program underscore the potential for the ICD-11 to reduce training costs and provide high-quality health data. Experiences and lessons learned from this study have contributed to WHO's work on the ICD-11 and can inform other countries when formulating their transition plan.

Complex posttraumatic stress disorder in adolescence: A two-year follow-up study

BACKGROUND

Complex posttraumatic stress disorder is a new diagnosis in the 11th edition of the International Classification of Diseases (ICD-11). There is a need for a better understanding of complex PTSD in children and adolescents.

OBJECTIVE

The study aimed to estimate the factors associated with chronic complex PTSD versus recovery of complex PTSD in adolescents in a 2-year follow-up study.

METHOD

In total, 66 adolescents, mean age 14.5, 73% female, identified as having complex PTSD using self-report at baseline recruited from a general population sample, were included in the study. The International Trauma Questionnaire - Child and Adolescent Version (ITQ-CA) was used for the assessment of complex PTSD.

RESULTS

Overall, 36% of the study sample has been identified as having chronic complex PTSD over 2 years, 10% met the criteria for PTSD at a 2-year follow-up, and 54% recovered. A higher risk for chronic complex PTSD was associated with exposure to more traumatic events and more life-stressors over the 2 years, low social network, low positive social support, bullying at school, and loneliness.

CONCLUSION

The study found that around one-third of the traumatized youth had a prolonged trajectory of complex PTSD symptoms, which were associated with negative life experiences and social difficulties.

Development of the complex trauma screener: A brief measure of ICD-11 PTSD and complex PTSD

The purpose of this study was to develop the Complex Trauma Screener (CTS), a brief screener (seven items) of the ICD-11 trauma disorders that can be used in "quick-paced" facilities. We examined the factor structure of the CTS in two separate samples: civilian college students (N = 823) and military veterans (N = 130) who reported exposure to at least one traumatic event. Confirmatory factor analyses (CFAs) supported two highly-correlated factors (post-traumatic stress disorder [PTSD] and Disturbances in Self-Organization [DSO]) that loaded on the ICD-11-consistent items. The model fit indices indicated good to excellent model fit in both samples, and the internal consistencies for the scales were borderline to good (α = 0.68-0.86). Supplementary analyses supported the gender invariance of the CFA model in the civilian student sample, as well as convergent (with another trauma inventory) and discriminant validity (with borderline disorder features, depression, and mania) of the CTS in both samples. The CTS is, to our knowledge, the shortest instrument designed to measure the ICD-11 trauma disorders and is ideal for "fast-paced" facilities that have significant assessment time restraints. The CTS is, therefore, is a psychometrically-validated instrument that can help mental health professionals efficiently screen adults for ICD-11 trauma disorders.

A network analysis of ICD-11 Complex PTSD, emotional processing, and dissociative experiences in the context of psychological trauma at different developmental stages

Objective

Traumatic experiences are a significant risk factor for psychological disturbances, including disorders such as complex posttraumatic stress disorder, emotion-processing problems, and trauma-related dissociative experiences. The present investigation examined the coexistence of these symptoms using a network analysis model.

Method

This study included a sample of 406 people referred to comprehensive health centers in Tehran from September to December 2023 with psychopathological syndromes. Variables were assessed using The International Trauma Questionnaire, International Measurement of Exposure to Traumatic Event checklist, Baker Emotional Processing Questionnaire, and Dissociative Experiences. A regularized partial correlation network and Glasso algorithm, in combination with Extended Bayesian information criteria, were applied to estimate the network structure.

Results

Signs of unprocessed emotions and disturbance in self-organization symptoms were the most important symptoms in the symptom network, forming strong connections with other nodes. Thereby, these two symptoms can be regarded as the most important clinical manifestations in the symptom network following traumatic experiences. Three distinct symptom communities were identified: the community of traumatic experiences (childhood, adolescence, adulthood), the community of dissociative experiences (amnesia, depersonalization/derealization, and absorption), and the community of emotional processing (suppression, unpleasant emotional experience, Signs of unprocessed emotions, avoidance, and emotional control, posttraumatic stress disorder symptoms and disturbance in self-organization symptoms). The strongest edges observed were between childhood trauma-adolescence trauma (0.473) in the community of traumatic experiences, between amnesia and depersonalization/derealization (0.644) in the community of dissociative experiences, and between disturbance in self-organization symptoms and unprocessed emotions (0.324) in the community of emotional processing, indicating the recurrent occurrence of these symptoms.

Conclusion

In this study, disturbance in self-organization symptoms was identified as the central psychopathologic symptom in individuals experiencing traumas at different developmental stages. It seems that adolescent trauma and not childhood trauma plays a more decisive role in the symptoms that a person manifests after traumatic experiences. Also, posttraumatic stress disorder symptoms and disturbance in self-organization symptoms were recognized in the cluster of emotional processing symptoms and can have substantial roles in prioritizing therapeutic measures.

Improving Quality of ICD-10 (International Statistical Classification of Diseases, Tenth Revision) Coding Using AI: Protocol for a Crossover Randomized Controlled Trial

BACKGROUND

Computer-assisted clinical coding (CAC) tools are designed to help clinical coders assign standardized codes, such as the ICD-10 (International Statistical Classification of Diseases, Tenth Revision), to clinical texts, such as discharge summaries. Maintaining the integrity of these standardized codes is important both for the functioning of health systems and for ensuring data used for secondary purposes are of high quality. Clinical coding is an error-prone cumbersome task, and the complexity of modern classification systems such as the ICD-11 (International Classification of Diseases, Eleventh Revision) presents significant barriers to implementation. To date, there have only been a few user studies; therefore, our understanding is still limited regarding the role CAC systems can play in reducing the burden of coding and improving the overall quality of coding.

OBJECTIVE

The objective of the user study is to generate both qualitative and quantitative data for measuring the usefulness of a CAC system, Easy-ICD, that was developed for recommending ICD-10 codes. Specifically, our goal is to assess whether our tool can reduce the burden on clinical coders and also improve coding quality.

METHODS

The user study is based on a crossover randomized controlled trial study design, where we measure the performance of clinical coders when they use our CAC tool versus when they do not. Performance is measured by the time it takes them to assign codes to both simple and complex clinical texts as well as the coding quality, that is, the accuracy of code assignment.

RESULTS

We expect the study to provide us with a measurement of the effectiveness of the CAC system compared to manual coding processes, both in terms of time use and coding quality. Positive outcomes from this study will imply that CAC tools hold the potential to reduce the burden on health care staff and will have major implications for the adoption of artificial intelligence-based CAC innovations to improve coding practice. Expected results to be published summer 2024.

CONCLUSIONS

The planned user study promises a greater understanding of the impact CAC systems might have on clinical coding in real-life settings, especially with regard to coding time and quality. Further, the study may add new insights on how to meaningfully exploit current clinical text mining capabilities, with a view to reducing the burden on clinical coders, thus lowering the barriers and paving a more sustainable path to the adoption of modern coding systems, such as the new ICD-11.

Improvements in Neoplasm Classification in the International Classification of Diseases, Eleventh Revision: Systematic Comparative Study With the Chinese Clinical Modification of the International Classification of Diseases, Tenth Revision

BACKGROUND

The International Classification of Diseases, Eleventh Revision (ICD-11) improved neoplasm classification.

OBJECTIVE

We aimed to study the alterations in the ICD-11 compared to the Chinese Clinical Modification of the International Classification of Diseases, Tenth Revision (ICD-10-CCM) for neoplasm classification and to provide evidence supporting the transition to the ICD-11.

METHODS

We downloaded public data files from the World Health Organization and the National Health Commission of the People's Republic of China. The ICD-10-CCM neoplasm codes were manually recoded with the ICD-11 coding tool, and an ICD-10-CCM/ICD-11 mapping table was generated. The existing files and the ICD-10-CCM/ICD-11 mapping table were used to compare the coding, classification, and expression features of neoplasms between the ICD-10-CCM and ICD-11.

RESULTS

The ICD-11 coding structure for neoplasms has dramatically changed. It provides advantages in coding granularity, coding capacity, and expression flexibility. In total, 27.4% (207/755) of ICD-10 codes and 38% (1359/3576) of ICD-10-CCM codes underwent grouping changes, which was a significantly different change (χ21=30.3; P<.001). Notably, 67.8% (2424/3576) of ICD-10-CCM codes could be fully represented by ICD-11 codes. Another 7% (252/3576) could be fully described by uniform resource identifiers. The ICD-11 had a significant difference in expression ability among the 4 ICD-10-CCM groups (χ23=93.7; P<.001), as well as a considerable difference between the changed and unchanged groups (χ21=74.7; P<.001). Expression ability negatively correlated with grouping changes (r=-.144; P<.001). In the ICD-10-CCM/ICD-11 mapping table, 60.5% (2164/3576) of codes were postcoordinated. The top 3 postcoordinated results were specific anatomy (1907/3576, 53.3%), histopathology (201/3576, 5.6%), and alternative severity 2 (70/3576, 2%). The expression ability of postcoordination was not fully reflected.

CONCLUSIONS

The ICD-11 includes many improvements in neoplasm classification, especially the new coding system, improved expression ability, and good semantic interoperability. The transition to the ICD-11 will inevitably bring challenges for clinicians, coders, policy makers and IT technicians, and many preparations will be necessary.

Practical implications of ICD-11 personality disorder classifications

Personality disorders (PDs) are associated with an inferior quality of life, poor health, and premature mortality, leading to heavy clinical, familial, and societal burdens. The International Classification of Diseases-11 (ICD-11) makes a thorough, dramatic paradigm shift from the categorical to dimensional diagnosis of PD and expands the application into adolescence. We have reviewed the recent literature on practical implications, and severity and trait measures of ICD-11 defined PDs, by comparing with the alternative model of personality disorders in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), by mentioning the relevance in forensic and social concerns, and by referencing the developmental implication of life span, especially in adolescence. Study results strongly support the dimensional utility of ICD-11 PD diagnosis and application in adolescence which warrants early detection and intervention. More evidence-based research is needed along the ICD-11 PD application, such as its social relevance, measurement simplification, and longitudinal design of lifespan observation and treatment.

Associations between olfactory reference disorder and social phobia - results of an internet-based study

Despite the similar clinical features of Olfactory Reference Disorder (ORD) and Social Phobia (SP), or studies showing elevated comorbidity of the two disorders, and the conceptualization of ORD as a form of SP in the East Asian culture, to our knowledge, the relationship between ORD and SP has not been investigated. This study examined the association of ORD according to the 11th revision of the International Classification of Diseases (ICD-11) and SP in 225 German university / college students who completed self-ratings with regard to socio-demographic data and symptoms of SP and ORD within an anonymous internet-based survey. Symptoms of SP were assessed with the Social Phobia Inventory (SPIN). Symptoms of ORD according to the ICD-11 were assessed with the Olfactory Reference Disorder Questionnaire (ORDQ), developed for this study. In our sample, 86.6% of the participants who met the self-rated features for ORD also met the self-rated criteria for current SP. ORD severity scores were significantly related to SP. Participants with and without self-reported ORD differed significantly in their SP total scores. SP severity was also significantly correlated with poorer insight of ORD-related beliefs, greater ORD-related avoidance of intimate relationships and higher levels of shame and fear of rejection due to body odor. These preliminary findings indicate that ORD could be closely related to SP and highlight the need for future research on the relationship of ORD and SP in order to gain a better understanding of the development, maintenance, treatment and classification of ORD.

Pain as a disease in the new International Classification of Diseases (ICD-11): Latin American expert consensus

Aims: Pain diagnoses in the 10th version of the International Classification of Diseases (ICD-10) did not adequately support the current management of pain. Therefore, we aimed to review the new 11th revision (ICD-11) in order to analyze its usefulness for the management, coding, research and education of chronic pain from a Latin American perspective. Methods: The Latin American Federation of Associations for the Study of Pain convened a meeting of pain experts in Lima, Peru. Pain specialists from 14 Latin American countries attended the consensus meeting. Results: In ICD-11, chronic pain is defined as pain that persists or recurs longer than 3 months and is subdivided into seven categories: chronic primary pain and six types of chronic secondary pain. Chronic primary pain is now considered a disease in itself, and not a mere symptom of an underlying disease. Conclusion: The novel definition and classification of chronic pain in ICD-11 is helpful for better medical care, research and health statistics. ICD-11 will improve chronic pain management in Latin American countries, for both the pain specialist and the primary care physician.

Dissociative Symptoms in Complex Posttraumatic Stress Disorder: A Systematic Review

The 11th revision of the International Classification of Diseases (ICD-11) introduced Complex Posttraumatic Stress Disorder (CPTSD) as a sibling disorder to PTSD. Dissociative symptoms have been implicated in the severity of ICD-11 CPTSD; however, no reviews have investigated how dissociation has been measured in studies investigating CPTSD, nor the relationship between CPTSD and dissociation. This systematic review aimed to identify measures used to assess dissociative symptoms in studies that have assessed CPTSD according to ICD-11 criteria and to synthesize the relationship between these constructs. PsycINFO, PubMed, Scopus and Web of Science were searched on March 31, 2021. Seventeen articles met inclusion criteria. CPTSD was most frequently measured by a version of the International Trauma Questionnaire. Twelve measures were used to assess for dissociative symptoms, the most common being the Dissociative Symptoms Scale and the Dissociative Experiences Scale. The relationship between CPTSD and dissociative symptoms was moderate-to-strong, but inconsistently reported. Further research is needed to determine the most appropriate measure(s) of dissociation in CPTSD.

Can personality disorder be accurately assessed in older age? A differential item functioning analysis of ICD-11 inventories

OBJECTIVES

The contested categorical personality disorder (PD) criteria are not well suited to inform PD diagnoses in older adults. Yet, the classification of PDs is undergoing a critical transition phase with a paradigm shift to a dimensional approach for diagnosing PDs. No special attention was given to the expression of PDs in older age when the dimensional ICD-11 model was developed. Given that PDs are highly prevalent in older adults, there is an urgent need to examine if ICD-11 related instruments are able to adequately assess for PDs in older adults.

METHODS

The age-neutrality of ICD-11 measures was examined in a sample of 208 Dutch community-dwelling adults (N = 208, M age = 54.96, SD = 21.65), matched on sex into 104 younger (age range 18-64) and 104 older (age range 65-93) adults. An instrument is considered not to be age-neutral if a collective large level of differential item functioning (DIF) exists in a group of items of an instrument (i.e., 25% or more with DIF). We therefore set out to detect possible DIF in the following ICD-11 self-report measures: the Standardized Assessment of Severity of Personality Disorder (SASPD), the Personality Inventory for ICD-11 (PiCD), and the Borderline Pattern Scale (BPS).

RESULTS

DIF analyses using a non-parametric odds ratio approach demonstrated that SASPD, PiCD, and BPS were age-neutral with less than 25% of items showing DIF. Yet, impact of DIF at scale level, examined by way of differential test functioning (DTF), indicated a DTF effect on the SASPD total score.

CONCLUSIONS

These results of age-neutrality of the PiCD and BPS are promising for measuring ICD-11 traits and the borderline pattern. Yet, the age-neutral measurement of PD severity requires further research. With a rapidly aging population, its accurate assessment across the entire adult life span, including older age, is a prerequisite for an adequate detection of PDs.

Trajectories of pain and opioid use up to one year after surgery: analysis of a European registry

BACKGROUND

Long-term opioid use after surgery is a crucial healthcare problem in North America. Data from European hospitals are scarce and differentiation of chronic pain has rarely been considered.

METHODS

In a mixed surgical cohort of the PAIN OUT registry, opioid use and chronic pain were evaluated before surgery, and 6 and 12 months after surgery (M6/M12). Subgroups with or without opioid medication and pre-existing chronic pain were analysed. M12-chronic pain was categorised as chronic postsurgical pain (CPSP) meeting the ICD-11 definition, chronic pain related to surgery not meeting the ICD-11 definition, and chronic pain unrelated to surgery. Primary endpoint was the rate of M12 opioid users. Variables associated with M12 opioid use and patient-reported outcomes were evaluated.

RESULTS

Of 2326 patients, 5.5% were preoperative opioid users; 4.4% and 3.5% took opioids at M6 and M12 (P<0.001). Chronic pain before operation and at M6/M12 was reported by 41.2%, 41.8%, and 34.7% of patients, respectively (P<0.001). The rate of M12 opioid users was highest in group unrelated (22.3%; related 8.3%, CPSP 1.5%; P<0.001). New opioid users were 1.1% (unrelated 7.1%, related 2.3%, CPSP 0.7%; P<0.001). M12 opioid users reported more pain, pain-related physical and affective interference, and needed more opioids than non-users. The predominant variable associated with M12 opioids was preoperative opioid use (estimated odds ratio [95% confidence interval]: 28.3 [14.1-56.7], P<0.001).

CONCLUSIONS

Opioid use was low in patients with CPSP, and more problematic in patients with chronic pain unrelated to surgery. A detailed assessment of chronic pain unrelated or related to surgery or CPSP is necessary.

Prolonged grief disorder in ICD-11 and DSM-5-TR: differences in prevalence and diagnostic criteria

Background

Prolonged grief disorder (PGD) was recently included as a disorder in the ICD-11 and DSM-5-TR. Although both classification systems use the same name, the criteria content, and diagnostic approach vary. This study aimed to estimate the respective prevalence of PGDICD-11 and PGDDSM-5-TR and examine the diagnostic agreement while varying the diagnostic algorithm of PGDICD-11 (bereavement vs. symptom period; varying number of accessory symptoms).

Methods

A representative sample of the German general population (N = 2,509) was investigated, of which n=1,071 reported the loss of a close person. PGD symptoms were assessed with the Traumatic Grief Inventory - Self Report Plus (TGI-SR+).

Results

The point prevalence of PGD among the bereaved varied between 4.7%-6.8%, depending on the criteria and diagnostic algorithm. The prevalence of PGDDSM-5-TR was significantly lower than the prevalence of PGDICD-11. The diagnostic agreement between both criteria sets was substantial and increased after the number of accessory symptoms for PGDICD-11 was increased from one to three. The most common symptoms were intrusive thoughts/images related to the deceased person, longing for the deceased person, and difficulty accepting the loss.

Conclusion

The results demonstrate that the prevalence of PGD significantly varies depending on the application of the diagnostic algorithm and criteria. PGD affects a substantial proportion of the general population and should be addressed by healthcare providers. However, applying the minimum ICD-11 criteria could lead overestimating the prevalence. Therefore, further harmonizing the ICD-11 and DSM-5-TR criteria and diagnostic algorithm for PGD seems appropriate.

Development of a Korean version of simple, intuitive descriptions for clinical use of the generic functioning domains in the ICD-11 Chapter V

PURPOSE

To develop a Korean version of simple, intuitive descriptions (SIDs) for clinical use of the generic functioning domains in the International Classification of Disease 11th revision (ICD-11) Chapter V.

METHODS

The initial Korean SID version proposal for the International Classification of Functioning, Disability, and Health (ICF) Rehabilitation set was translated following the Italian version. The remaining 17 codes were developed using original ICF descriptions; WHO Disability Assessment Schedule, Model Disability Survey, Korean Classification of Functioning, Disability, and Health; and previous studies. The final proposal for the Korean version of SIDs was selected through virtual conferences and three rounds of voting.

RESULTS

This study developed SIDs for the 47 generic functioning domains in the Chapter V of ICD-11. However, the SID for 20 of the 47 codes was confirmed in vote A, for 23 codes in vote B and for the remaining 4 in the final vote. All experts agreed with the final SID proposal.

CONCLUSIONS

This is the first study in South Korea to attempt the development of SIDs for ICD-11 Chapter V. Therefore, the findings of this study could be used to evaluating of disability, functioning when ICD-11 is adopted for use in Korean clinical settings.

Clinical cut scores for the Persian version of the personality inventory for DSM-5

BACKGROUND

The cut points of psychological tools to diagnose clinical conditions are not universal and depend on the region and prevalence of the disorder. Thus, we aimed to identify the cutoff points of the Persian original version of the personality inventory for DSM-5 (PID-5; 220 items) that would optimally distinguish nonclinical from clinical groups.

METHODS

Both nonclinical (N = 634, 73% female, 34.0 ± 10.8 years) and clinical (N = 454, 29% female, 29.5 ± 7.4 years) samples from the West of Iran participated in the study. Data were analyzed using receiver operating characteristic (ROC) and Youden's index was used to determine the cutoff scores across the PID-5 domains and facets. The means and standard deviations of both the clinical male and female were compared with the nonclinical group using Cohen's d and independent t-tests.

RESULTS

All the PID-5 algorithms and facets significantly distinguished clinical from nonclinical samples with some unique findings for male and female samples. The mean score of all the PID-5 algorithms and facets in the clinical male and female samples were respectively 1.0-2.0 SD and 0.5-1.0 SD above the mean for the nonclinical counterparts. A score higher than 1.5 on ranging from 0 to 3 in each domain or facet indicated clinical status.

CONCLUSION

Raw cutting scores throughout the PID-5 algorithms can be well used to diagnose any pathology of personality and the severity of the disorder in clinical patients. The cut scores provide a useful tool for the clinical use of the original version of PID-5 in Iran.

Examining accurate diagnosis of complex PTSD in ICD-11

BACKGROUND

Complex posttraumatic stress disorder (complex PTSD), the most frequently suggested new category for inclusion by mental health professionals, has been included in the Eleventh Revision of the World Health Organization's International Classification of Diseases (ICD-11). Research has yet to explore whether clinicians' recognition of the distinct complex PTSD symptoms predicts giving the correct diagnosis. The present study sought to determine if international mental health professionals were able to accurately diagnose complex PTSD and identify the shared PTSD features and three essential diagnostic features, specific to complex PTSD.

METHODS

Participants were randomly assigned to view two vignettes and tasked with providing a diagnosis (or indicating that no diagnosis was warranted). Participants then answered a series of questions regarding the presence or absence of each of the essential diagnostic features specific to the diagnosis they provided.

RESULTS

Clinicians who recognized the presence or absence of complex PTSD specific features were more likely to arrive at the correct diagnostic conclusion. Complex PTSD specific features were significant predictors while the shared PTSD features were not, indicating that attending to each of the specific symptoms was necessary for diagnostic accuracy of complex PTSD.

LIMITATIONS

The use of written case vignettes including only adult patients and a non-representative sample of mental health professionals may limit the generalizability of the results.

CONCLUSIONS

Findings support mental health professionals' ability to accurately identify specific features of complex PTSD. Future work should assess whether mental health providers can effectively identify symptoms of complex PTSD in a clinical setting.

An ICD for the Digital World: What Does the ICD-11 Research Show?

The 11th revision of the International Classification of Diseases (ICD) is now available for use. A literature search was conducted to review and summarize the research conducted to date. In addition to the ease of integration into electronic health records using standard digital tools such as uniform resource identifiers and application programming interfaces, ICD-11 and the World Health Organization provided linearization for mortality and morbidity, ICD-11-MMS, promise improved backward compatibility to ICD-10; increased availability in multiple languages; greater detail for clinical use, including traditional Chinese medicine; and enhanced maintenance for continued relevance. The studies reviewed here support the superior content and utility of ICD-11-MMS. Meaningful planning for implementation has begun, including the provision of a framework. It is time for the world to adopt a digitally prepared ICD.

Responding to concerns related to the measurement of ICD-11 complex posttraumatic stress disorder using the International Trauma Questionnaire

BACKGROUND

A recent study in this journal by Frewen et al. (2023) provided a critical analysis of the most widely used measure of ICD-11 Complex Posttraumatic Stress Disorder (CPTSD), the International Trauma Questionnaire (ITQ). The article was a thoughtful review and gave voice to several widely held concerns about the nature of CPTSD as it is represented in ICD-11 and measured by the ITQ. The primary concern expressed by Frewen et al. was that the symptom profile of ICD-11 CPTSD, as represented in the ITQ, is too simple and fails to provide adequate coverage of the construct.

OBJECTIVE

Despite its quality, the article included several misunderstandings about the nature of ICD-11 CPTSD, and the function of the ITQ, that we wish to clarify.

PARTICIPANTS

Not applicable.

SETTING

Not applicable.

RESULTS

In this article, we provide a description of what ICD-11 PTSD and CPTSD are, a review of the process that led to their inclusion in ICD-11, how the ITQ was developed and refined to measure these constructs. We then provide responses to several of the most important concerns raised by Frewen et al. CONCLUSIONS: We highlight the clinical utility of the ICD-11 descriptions of PTSD and CPTSD and discuss how the ITQ can be used as part of a suite of clinical assessments to accurately describe and understand common experiences of psychological distress that often result from exposure to traumatic life events.

The smoldering pandemic: Prevalence of prolonged grief disorder. A cross-sectional study of bereaving adults during the COVID pandemic in Pakistan

The world continues to face unprecedented psycho-social challenges after the COVID-19 pandemic. Prolonged Grief Disorder (PGD) is a young psychiatric condition describing grief exceeding standard cultural, social, and religious norms. We assessed the prevalence of PGD in Pakistan along with its correlation to anxiety, depression, and psychological distress. The prevalence of PGD was estimated to be 15 % with grief intensity correlating with depression, anxiety, and serious mental illness. People who were closely related to the deceased were more likely to experience severe PGD symptoms. Discussions about grief and measures to curb its psychological effects are crucial in the post-pandemic world.

Extension, translation and preliminary validation of the Northoff Scale for Subjective Experience in Catatonia (NSSC)

BACKGROUND

In the last two decades, much neuroscientific research has been done on the pathomechanisms of catatonia. However, catatonic symptoms have mainly been assessed with clinical rating scales based on observer ratings. Although catatonia is often associated with strong affective reactions, the subjective domain of catatonia has simply been neglected in scientific research.

METHODS

The main objective of this study was to modify, extend and translate the original German version of the Northoff Scale for Subjective Experience in Catatonia (NSSC) and to examine its preliminary validity and reliability. Data were collected from 28 patients diagnosed with catatonia associated with another mental disorder (6A40) according to ICD-11. Descriptive statistics, correlation coefficients, internal consistency and principal component analysis were employed to address preliminary validity and reliability of the NSSC.

RESULTS

NSSC showed high internal consistency (Cronbach's alpha = 0.92). NSSC total scores were significantly associated with Northoff Catatonia Rating Scale (r = 0.50, p < .01) and Bush Francis Catatonia Rating Scale (r = 0.41, p < .05) thus supporting its concurrent validity. There was no significant association between NSSC total score and Positive and Negative Symptoms Scale total (r = 0.26, p = .09), Brief Psychiatric Rating Scale (r = 0.29, p = .07) and GAF (r = 0.03, p = .43) scores.

CONCLUSION

The extended version of the NSSC consists of 26 items and was developed to assess the subjective experience of catatonia patients. Preliminary validation of the NSSC revealed good psychometric properties. NSSC is a useful tool for everyday clinical work to assess the subjective experience of catatonia patients.

A head-to-head comparison of eight unique personality systems in predicting somatization phenomenon

BACKGROUND

If somatization is an independent personality trait, it is not clear whether it is specific to the temperament or maladaptive spectrum of personality. We aimed at the head-to-head comparison of temperament and maladaptive systems and spectra of personality to predict both somatization and somatic symptom and related disorders (SSRD).

METHODS

The samples included 257 cases with SSRD (70.8% female) and 1007 non-SSRD (64.3% female) from Western Iran. The Personality Inventory for DSM-5 (PID-5), Personality Diagnostic Questionnaire-4 (PDQ-4), Temperament and Character Inventory (TCI), Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A), Affective and Emotional Composite Temperament Scale (AFECTS), and Positive Affect and Negative Affect Model (PANAS) was used to data collection. A somatization factor plus temperament and maladaptive spectra of personality were extracted using exploratory factor analysis. Several hierarchical linear and logistic regressions were used to test the predictive systems and spectra.

RESULTS

All personality systems jointly predict both somatization and SSRD with a slightly higher contribution for temperament systems. When the temperament and maladaptive spectra were compared, both spectra above each other significantly predicted both somatization (R2 = .407 versus .263) and SSRD (R2 = .280 versus .211). The temperament spectrum explained more variance beyond the maladaptive spectrum when predicting both the somatization factor (change in R2 = .156 versus .012) and SSRD (change in R2 = .079 versus .010).

CONCLUSION

All temperament and maladaptive frameworks of personality are complementary to predicting both somatization and SSRD. However, the somatization is more related to the temperament than the maladaptive spectrum of personality.
