Elemental psychopathology: distilling constituent symptoms and patterns of repetition in the diagnostic criteria of the DSM-5.

BACKGROUND: The DSM-5 features hundreds of diagnoses comprising a multitude of symptoms, and there is considerable repetition in the symptoms among diagnoses. This repetition undermines what we can learn from studying individual diagnostic constructs because it can obscure both disorder- and symptom-specific signals. However, these lost opportunities are currently veiled because symptom repetition in the DSM-5 has not been quantified. METHOD: This descriptive study mapped the repetition among the 1419 symptoms described in 202 diagnoses of adult psychopathology in section II of the DSM-5. Over a million possible symptom comparisons needed to be conducted, for which we used both qualitative content coding and natural language processing. RESULTS: In total, we identified 628 distinct symptoms: 397 symptoms (63.2%) were unique to a single diagnosis, whereas 231 symptoms (36.8%) repeated across multiple diagnoses a total of 1022 times (median 3 times per symptom; range 2-22). Some chapters had more repetition than others: For example, every symptom of every diagnosis in the bipolar and related disorders chapter was repeated in other chapters, but there was no repetition for any symptoms of any diagnoses in the elimination disorders, gender dysphoria or paraphilic disorders. The most frequently repeated symptoms included insomnia, difficulty concentrating, and irritability - listed in 22, 17 and 16 diagnoses, respectively. Notably, the top 15 most frequently repeating diagnostic criteria were dominated by symptoms of major depressive disorder. CONCLUSION: Overall, our findings lay the foundation for a better understanding of the extent and potential consequences of symptom overlap.

Personality disorder coverage, prevalence, and convergence: do the DSM-5's two models of personality disorder identify the same patients?

BACKGROUND: Research on the Alternative DSM-5 Model for Personality Disorders (AMPD) in DSM-5's Section-III has demonstrated acceptable interrater reliability, a largely consistent latent structure, substantial correlations with theoretically and clinically relevant measures, and evidence for incremental concurrent and predictive validity after controlling for DSM-5's Section II categorical personality disorders (PDs). However, the AMPD is not yet widely used clinically. One clinician concern may be caseness - that the new model will diagnose a different set of PD patients from that with which they are familiar. The primary aim of this study is to determine whether this concern is valid, by testing how well the two models converge in terms of prevalence and coverage. METHOD: Participants were 305 psychiatric outpatients and 302 community residents not currently in mental-health treatment who scored above threshold on the Iowa Personality Disorder Screen (Langbehn et al., ). Participants were administered a semi-structured interview for DSM-5 PD, which was scored for both Section II and III PDs. RESULTS: Convergence across the two PD models was variable for specific PDs, Good when specific PDs were aggregated, and Very Good for 'any PD.' CONCLUSIONS: Results provide strong evidence that the AMPD yields the same overall prevalence of PD as the current model and, further, identifies largely the same overall population. It also addresses well-known problems of the current model, is more consistent with the ICD-11 PD model, and provides more complete, individualized characterizations of persons with PD, thereby offering multiple reasons for its implementation in clinical settings.

Validity of the DSM-5 Mixed Features Specifier Interview.

OBJECTIVES: To examine the reliability and validity of a semi-structured interview assessing the features of the DSM-5 mixed features specifier. Our goal was to develop an instrument that could be used for both diagnostic and severity measurement purposes. METHODS: Four hundred fifty-nine psychiatric patients in a depressive episode were interviewed by a trained diagnostic rater who administered semi-structured interviews including the DSM-5 Mixed Features Specifier Interview (DMSI). We examined the inter-rater reliability and psychometric properties of the DMSI. The patients were rated on clinician rating scales of depression, anxiety, and irritability, and measures of psychosocial functioning, suicidality, and family history of bipolar disorder. RESULTS: The DMSI had excellent joint-interview interrater reliability. More than twice as many patients met the DSM-5 mixed features specifier criteria during the week before the assessment than for the majority of the episode (9.4% vs. 3.9%). DMSI total scores were more highly correlated with a clinician-rated measure of manic symptoms than with measures of depression and anxiety. More patients with bipolar depression met the mixed features specifier than patients with MDD. Amongst patients with MDD, those with mixed features more frequently had a family history of bipolar disorder, were more frequently diagnosed with anxiety disorders, attention deficit disorder, and borderline personality disorder, more frequently had attempted suicide, and were more severely depressed, anxious, and irritable. CONCLUSION: The DMSI is a reliable and valid measure of the presence of the DSM-5 mixed features specifier in depressed patients as well as the severity of the features of the specifier.

The Treatment Needs and Experiences of Pedohebephiles: A Systematic Review.

People with a sexual interest in children face significant barriers to seeking and receiving mental health treatment. This review aims to bridge the gap between the treatment needs and experiences of pedohebephiles, and the services aiming to support them. Reviewers screened 1705 database hits and extracted findings from 22 qualitative, 15 quantitative, and 3 mixed-method studies on the treatment needs and experiences of pedohebephiles. Research suggests that this population experiences significant levels of distress, depression, and anxiety related to their sexual interest. Many individuals belonging to this population would seek (median = 42.3%), or have sought (median = 46.5%), treatment to cope with their sexual interest or with potential related mental health repercussions. Their experiences in treatment have been mixed, with some reporting positive experiences with empathic therapists and others reporting rejection. Most frequently, pedohebephiles report fear of exposure and rejection as barriers to seeking treatment, in addition to fear of the legal repercussions. The current study is the first to summarize and discuss previous findings on the treatment needs and experiences of pedohebephiles. The findings indicate that the treatment needs of pedohebephiles often remain unaddressed. Suggestions to increase the fit between treatment services and the needs of pedohebephiles are put forward.

Detransition and Desistance Among Previously Trans-Identified Young Adults.

Persons who have renounced a prior transgender identification, often after some degree of social and medical transition, are increasingly visible. We recruited 78 US individuals ages 18-33 years who previously identified as transgender and had stopped identifying as transgender at least six months prior. On average, participants first identified as transgender at 17.1 years of age and had done so for 5.4 years at the time of their participation. Most (83%) participants had taken several steps toward social transition and 68% had taken at least one medical step. By retrospective reports, fewer than 17% of participants met DSM-5 diagnostic criteria for Gender Dysphoria in Childhood. In contrast, 53% of participants believed that "rapid-onset gender dysphoria" applied to them. Participants reported a high rate of psychiatric diagnoses, with many of these prior to trans-identification. Most participants (N = 71, 91%) were natal females. Females (43%) were more likely than males (0%) to be exclusively homosexual. Participants reported that their psychological health had improved dramatically since detransition/desistance, with marked decreases in self-harm and gender dysphoria and marked increases in flourishing. The most common reason given for initial trans-identification was confusing mental health issues or reactions to trauma for gender dysphoria. Reasons for detransition were more likely to reflect internal changes (e.g., the participants' own thought processes) than external pressures (e.g., pressure from family). Results suggest that, for some transgender individuals, detransition is both possible and beneficial.

Neuropsychological Functioning in Sexual Offenders With and Without Pedophilic Disorder.

This study sought to examine neuropsychological functioning in men with pedophilic disorder (PD), in order to assess whether findings from prior neuropsychological studies are replicated in a diverse sample including men with non-contact sexual offenses. It was hypothesized that when non-contact offenders are included in the study, a slowed processing speed will emerge as the only finding unique to men with PD. A comprehensive neuropsychological battery was administered to 58 men convicted of a sexual offense, 20 of whom were classified as having PD. The sample included men with contact sexual offenses (n = 33), non-contact sexual offenses (n = 5), and child sexual abuse material (CSAM) offenses (n = 20). Test performance was compared by PD status. Participants with PD performed significantly better on verbal memory and visual discrimination than those without PD. Men with PD made more errors on a set-shifting task but no significant differences were seen in domains of attention, intellectual functioning, visual learning and memory, visuospatial ability, or language ability. Effect sizes were generally small, although some medium effects were seen (visual discrimination and verbal learning and memory). Scores in both groups (with and without PD) were generally in the average range across tasks. Within the subgroup of CSAM offenders, minimal differences emerged between those with and without PD, although those with PD were slower on visuomotor set-shifting but made fewer errors (d = - 0.89). CSAM offenders with PD were in the high average range on many tasks of intellectual functioning; however, a potential trend was identified such that CSAM offenders without PD had lower scores on a task of verbal learning and memory, with medium effect sizes observed. As few differences in neuropsychological functioning emerged when comparing offenders with and without PD, differences demonstrated in prior research may be better attributed to contact offending status rather than sexual interest.

Interest in and Willingness to Use PrEP: A Cross-Sectional Study of Individuals with Problematic Substance Use Residing in a High HIV Prevalence Jurisdiction.

Although it is an effective HIV prevention method, pre-exposure prophylaxis (PrEP) is underutilized in the Southern US. Many people who use drugs (PWUD) have increased susceptibility to HIV which could be lessened by using PrEP. Potential barriers to PrEP use include lack of awareness of PrEP, low knowledge about HIV prevention, low self-efficacy for HIV prevention, inaccurate risk perceptions, and anticipated stigma. The current study examined predisposing, enabling, and reinforcing factors that may predict interest in PrEP. The purpose of the current study was to explore factors associated with interest in and willingness to use daily oral and long acting injectable PrEP among sexually active adult PWUD. The data were collected from adult participants (n = 270) residing in Harris County, TX, who self-reported problematic substance use and who reported oral, anal, or vaginal sex in the six months prior to completing the survey. The survey was distributed and completed online via Qualtrics Panels in March of 2022 and included measures of PrEP and HIV knowledge, PrEP stigma, sexual health self-efficacy, experiences of discrimination, health literacy, and medical mistrust. The majority of participants reported circumstances or behaviors that increased their susceptibility to HIV. Findings indicated that PrEP user stereotypes and PrEP anticipated disapproval by others were associated with interest in using daily oral PrEP and willingness to use long acting injectable PrEP. These results provide insight into reasons for low PrEP uptake among PWUD who live in a high HIV prevalence jurisdiction. Implications for HIV prevention intervention are discussed.

Associations Between Forced Intercourse and Subsequent Depression Among Women in the U.S. General Population.

Forced intercourse is a high prevalence experience among US women, with high potential to produce subsequent major depressive episodes (MDE). However, the extent to which prior risk factors are associated with the timing of both sexual assault experiences and subsequent MDE onset is not known. The aim of this study was to document the associations between childhood depression, subsequent forced intercourse, and later MDE. We used retrospective information on childhood depression, forced intercourse, and MDE after forced intercourse from female respondents in the nationally representative 2017 US Panel Study of Income Dynamics-Transition to Adulthood Supplement (PSID-TAS, N = 1298, response rate: 87%). Multivariable logistic regression estimated these associations, controlling for age, race, poverty, religiosity, family history of depression, and adverse childhood experiences (such as parental physical abuse or parental violence). Women who experienced childhood depression (prevalence: 15%) had 2.57 times the odds of experiencing forced intercourse after depression onset, even after adjusting for these other risk factors. However, even though childhood depression is a powerful risk factor for later MDE, independent of that women who experienced forced intercourse had 2.28 times the odds of experiencing MDE after the occurrence of forced intercourse, adjusting for childhood depression and other risk factors. This study provided the first clear evidence for time-ordered associations between forced intercourse and subsequent MDE among women in the general population.

An Evolutionary Psychological Approach Toward BDSM Interest and Behavior.

Bondage/discipline, Dominance/submission, and Sadism/Masochism (BDSM) have gained increased attention and discussion in recent years. This prevalence is accompanied by a shift in perceptions of BDSM, including the declassification of sadomasochism as a paraphilic disorder. Evolutionary psychology offers a unique perspective of why some individuals are interested in BDSM and why some prefer certain elements of BDSM over others (e.g., dominance versus submission). In this paper, we examine BDSM from an evolutionary standpoint, examining biopsychosocial factors that underlie the BDSM interests and practice. We articulate this perspective via an exploration of: proximate processes, such as the role of childhood experiences, sexual conditioning, and physiological factors; as well as ultimate explanations for power play and pain play dimensions of BDSM, highlighting the potential adaptive advantages of each. While BDSM may not be adaptive in itself, we examine the literature of sex differences in BDSM role preferences and argue that these preferences may stem from the extreme forms of behaviors which enhance reproductive success. In the realm of pain play, we explore the intersection of pain and pleasure from both physiological and psychological perspectives, highlighting the crucial role of psychological and play partner factors in modulating the experience of pain. Finally, we encourage future research in social sciences to utilize evolutionary frameworks to further explore the subject and help alleviate the mystification surrounding BDSM. This multifaceted exploration of BDSM provides valuable insights for clinicians, kink-identified individuals, and scholars seeking to understand the evolutionary perspectives of human sexual behavior and preferences.

Childhood Adversity and Offense-Supportive Cognitions Among Czech Adults with a Sexual Interest in Violence or Children.

Individuals with paraphilic interests in sexual violence or children may be more likely to sexually offend if they possess offense-supportive cognitions. These cognitions may develop in response to childhood adversity. However, this idea is largely based on research in men convicted of sexual offenses and may not generalize to non-incarcerated adults with paraphilic interests. In a sample of 178 adults screened for paraphilic interests in violence or children (from the general Czech population), we hypothesized that childhood sexual abuse and emotional neglect would be associated with offense-supportive cognitions about rape and child molestation. Participants came from a nationally representative sample of Czech adults and were selected if they self-reported high levels of sexual interest in violence and/or children. Participants completed an online survey with self-report measures of sexual orientation, offense-supportive cognitions (Bumby RAPE and MOLEST scales), and childhood sexual abuse and emotional neglect (Childhood Trauma Questionnaire). Controlling for gender, age, and sexual orientation, we found that both rape-supportive cognitions and child molestation-supportive cognitions were significantly associated with higher levels of childhood sexual abuse, but not emotional neglect. These findings indicate that childhood sexual abuse may lead to offense-supportive cognitions among men and women with paraphilia.

The Structure of Hypersexuality and Its Relation to Impulsivity.

Among the multiple controversies surrounding hypersexuality is the important issue of whether it constitutes a univocal construct. Although an initial study supported its homogeneity, more resent research has identified two separate subcomponents-problematic sexuality and sexual drive. The present survey study addressed this issue in a sample that included both in-person tested college students (n = 69) and online respondents (n = 339). A factor analysis of scales attempting to capture the indicators of each subcomponent of hypersexuality yielded two correlated, but separate factors. Whereas Problematic Sexuality (PS) comprised scales measuring sexual compulsivity, using sex as a coping mechanism, and the negative consequences of sexual behavior, Sexual Drive (SD) was defined by frequent sexual activity, preoccupation with sexual fantasies, a predilection for impersonal sexual behavior, and facile sexual arousal. These two subcomponents of hypersexuality were found to covary with different types of impulsivity, further supporting their discrimination and providing external validation for their differentiation. Contrary to a priori hypotheses, however, PS correlated highly with Callous/Manipulative/Risk-Taking as well as with a predicted Affective Instability/Behavioral Disinhibition factor, suggesting that PS may constitute an equifinality of separate developmental trajectories for those high on both subtypes of hypersexuality.

Mental Health Evaluation of Younger and Older Adolescents Referred to the Center of Expertise on Gender Dysphoria in Amsterdam, The Netherlands.

The present study aimed to investigate whether differences exist between younger and older presenting adolescents at the Center of Expertise on Gender Dysphoria regarding psychological functioning and autistic traits. A total of 1487 consecutively assessed adolescents between 2000 and 2018 were divided in younger presenters (age ≤ 13.9 years) and older presenters (age ≥ 14 years). Of younger presenters, 227 (41.1%) were assigned male at birth and 325 (58.9%) assigned female at birth. In older presenters, 279 (29.8%) were assigned male at birth and 656 (70.2%) assigned female at birth. Behavioral and emotional problems were assessed with the Child Behavior Checklist (CBCL) and the Youth Self-Report (YSR). For autism traits, the Social Responsiveness Scale (SRS) was used. Compared to younger presenters, on both the CBCL and YSR older presenters had higher Total Problem (ß = 1.75, p = .005, CI 0.53-2.97, R2 = .04 and ß = 4.20, p < .001, CI 2.99-5.40, R2 = .07, respectively) and Internalizing Problem (ß = 4.43, p < .001, CI 3.13-5.74, R2 = .06 and ß = 6.69, p < .001, CI 5.31-8.07, R2 = .12, respectively) scores. Regarding autistic traits, a higher mean SRS total score was found in older presenting assigned males at birth (ß = 4.55, p = .036, CI 0.30-8.81, R2 = .34). In assigned females at birth, no statistically significant difference between older and younger presenters was found in mean SRS total score (ß = 1.19, p = .063, CI - 0.07 to 2.45, R2 = .39). Differences in mental health exist between younger and older presenting adolescents and call for an individualized approach in the clinical care of transgender adolescents.

Themes Associated with Suicidal Ideation and Behavior Among People Attracted to Children.

Suicide represents a significant public health problem, with around 800,000 deaths per year worldwide and up to 20 times as many episodes of self-harm and suicide attempts. Members of stigmatized groups may experience increased risk of suicide due in part to stigma-related factors, such as expectations of rejection, internalization of negative stereotypes, or potential for greater social isolation. Research suggests that adults who are attracted to children face extreme stigma, even those who do not commit sexual crimes involving children. Adults who are attracted to children also experience significantly increased risk for suicidal ideation and behavior (SIB) compared to general population samples. The current study sought to explore experiences with SIB among adults attracted to children to better understand factors underlying suicidality in this population. The lead author conducted semi-structured interviews in a community sample of 15 adults attracted to children who self-reported some form of SIB in their lifetime. Using interpretative phenomenological analysis, the lead author explored and interpreted interview data to generate themes driven by respondents' characterizations of their SIB. Superordinate themes related to suicidality in this sample included low self-esteem or self-worth, cumulative impacts of the attraction and other stressors, and concerns about the ability to have a positive future due to the attraction. Findings underscore the importance of addressing internalized stigma, treating problems like depression and social isolation, and instilling hope for the future to promote mental health and prevent SIB among adults attracted to children.

Motivation When Desire Is Low: Associations Between Sexual Motivation and Sexual Intimacy, Sexual Satisfaction, and Sexual Distress for Men with Hypoactive Sexual Desire Disorder and Their Partners.

Hypoactive sexual desire disorder (HSDD) in men, characterized by chronically low sexual desire, is associated with poor sexual well-being, such as lower sexual satisfaction and higher sexual distress. Additionally, despite their low desire, men with HSDD often report wanting sexual intimacy and validation within their sexual lives/relationships. Studies that apply self-determination theory to sexual relationships demonstrate that adopting more autonomous (e.g., engaging in sex for its inherent pleasure) and less controlled (e.g., engaging in sex for some external reward or consequence) motives for engaging in sex is associated with greater sexual well-being for both members of the couple. Given that autonomous motivation in relationships is associated with intimacy and sexual satisfaction, and lower sexual distress, having sex for autonomous reasons may allow men with HSDD and their partners to feel more sexually intimate despite their lower sexual desire, whereas having sex for controlled reasons may hinder sexual intimacy and satisfaction and augment sexual distress. In this dyadic cross-sectional study, we examined the associations between types of sexual motivation and sexual intimacy, sexual satisfaction, and sexual distress for men with HSDD and their partners (n = 64 couples). Men with HSDD who reported having sex for more autonomous reasons reported more sexual satisfaction and both partners reported more sexual intimacy. Men with HSDD who had sex for more controlled reasons had partners who felt less sexual intimacy and satisfaction, and both partners were more sexually distressed. Promoting autonomous sexual motivation and decreasing controlled motivation may help couples navigating HSDD to feel closer in their relationship, more sexually satisfied, and less sexually distressed.

More Efficient Approach: Independent Diagnostic Value of Audiovisual Sexual Stimulation for Psychogenic Erectile Dysfunction.

The diagnostic value of audiovisual sexual stimulation (AVSS) for psychogenic erectile dysfunction (ED) is still unclear. We investigated the independent diagnostic value and optimal cut-off parameter of AVSS for psychogenic ED. All participants had received the AVSS test and nocturnal penile tumescence and rigidity (NPTR) monitoring at least twice. ED patients were divided into psychogenic ED and organic ED according to NPTR examination. The diagnostic accuracy of AVSS parameters was evaluated with the receiver operating characteristic (ROC) curve, and the Youden index was employed to determine the optimal diagnostic cut-off values. A total of 346 patients with ED and 60 healthy men were included in this study, among which 162 and 184 cases of psychogenic and organic ED were identified based on NPTR, respectively. When comparing the two ED groups, the area under the curve (AUC) of AVSS parameters was 0.85-0.89. Six-selected AVSS parameters could precisely diagnose psychogenic ED, exhibiting increased diagnostic specificity compared with corresponding sensitivity. When comparing psychogenic ED with the control group, the AUC of the tumescence of the tip was superior to the AUC other parameters (0.81 vs. 0.58, 0.66, 0.59, 0.53, 0.68), and the best determined diagnostic cut-off value was the tumescence of the tip < 29.87%. Independent AVSS could diagnose psychogenic ED objectively and effectively, and its diagnostic value was highest when 1.50% ≤ tumescence of the tip < 29.87%.

Differences in Subjective Transition Outcomes Between Transgender and Gender-Diverse Individuals Who Completed Mandatory Psychiatric Assessment and Those Who Received Gender-Affirmative Medical Treatment in Croatia: A Cross-Sectional Online Survey.

The aim of this study was to evaluate different aspects of transition outcomes in groups of transgender and gender diverse (TGD) people based on their transition status. We divided the 70 TGD participants (19 individuals assigned male at birth and 51 assigned female at birth) into two groups: those who had completed their psychiatric and psychological evaluation (PPE), which is mandatory in Croatia, and those who had undergone gender-affirming medical treatment (GAMT) (both gender-affirming hormone treatment and gender-affirming surgery). The online survey included sociodemographic questions and a custom-designed nine-item scale. The items were specifically designed based on the DSM-5-TR criteria for gender dysphoria to assess subjectively perceived transition outcomes. We conducted a factor analysis of the scale followed by structural equation modeling for confirmation. Chi-squared and Mann-Whitney U tests were used to compare group differences. The following three-factor structure was confirmed: better functioning, reduced body dysphoria, and satisfaction with decision. A positive influence of better functioning on satisfaction with the decision was found. In addition, our results showed that TGD individuals who had undergone GAMT scored higher on better functioning than those who had just completed PPE. Both groups consistently scored high on satisfaction with the decision, with no statistically significant differences between them. Our findings suggest that TGD individuals view gender-affirming medical care as beneficial to their overall functioning.

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.

Structured clinical interview for diagnosing obsessive-compulsive spectrum disorders.

BACKGROUND: There are several established structured diagnostic interviews that cover common mental disorders seen in general psychiatry clinics. The administration of more focused diagnostic interviews may be useful in specialty clinics, such as OCD clinics. A semi-structured clinician-administered interview for obsessive-compulsive spectrum disorders (SCID-OCSD) was developed and adapted for DSM-5/ICD-11 obsessive-compulsive and related disorders as well as other putative obsessive-compulsive spectrum conditions. OBJECTIVE: To introduce a semi-structured diagnostic interview for in-depth assessment of obsessive-compulsive spectrum disorders (OCSDs), and to report on its implementation in adults with primary OCD attending an OCD-specialized unit. METHODS: Patients with primary OCD were interviewed using the SCID-OCSD. The SCID-OCSD assesses disorders drawn from several diagnostic categories that share some core features of obsessive-compulsive phenomenology and that are often comorbid in OCD (e.g., obsessive-compulsive related disorders, impulse-control disorders, and a spectrum of compulsive-impulsive conditions such as tics, eating disorders, non-suicidal self-injury, and behavioral addictions. Participants had to be at least moderately symptomatic on the Yale-Brown Obsessive-Compulsive Severity scale (YBOCS, i.e., a total score ≥ 14) to be included in the current study. RESULTS: One hundred and one adult patients with current OCD (n = 101, 37 men and 64 women), took part in the study. Forty-two participants (n = 42) had OCD and one or more current or past comorbid OCSDs, with excoriation (skin-picking) disorder (n = 16) and body dysmorphic disorder (n = 14) being the most common. Nine (n = 9) participants reported a history of non-suicidal self-injury, and 6 participants reported a history of comorbid tics. CONCLUSIONS: In OCD clinics, the SCID-OCSD may help diagnose the full range of putative OCSDs, and so facilitate treatment planning and research on these conditions.

Posttraumatic stress disorder prevalence and childbirth: update meta-analysis after the introduction of the DSM-5 and COVID-19 pandemic.

PURPOSE: Meta-analyses were previously performed to estimate PTSD prevalence in the postpartum period. Significant events that could impact this outcome occurred in the last decade, such as the publication of the DSM-5 in 2013 and the COVID-19 pandemic in 2020. This systematic literature review with a meta-analysis addressed studies published after 2014 to estimate PTSD prevalence after childbirth. METHOD: The methodological guidelines recommended by PRISMA were followed. The meta-analysis estimate was the proportion of PTSD cases. The restricted maximum likelihood (REML) was the method adopted for estimation in addition to multilevel random effect models. Subgroup analyses were performed to assess the impact of interest variables. RESULTS: The estimated prevalence was 0.10 (95%CI: 0.8-0.13; I2 = 98.5%). No significant differences were found regarding the introduction of the DSM-5 (p = 0.73) or COVID-19 (p = 0.97), but instead, between low- and middle-income countries, e.g., the Middle East presents a higher prevalence (p < 0.01) than European countries. CONCLUSIONS: There is a potential increase in PTSD prevalence rates after childbirth in the last decade not associated with the pandemic or the current diagnostic classification. Most studies showed a methodological fragility that must be overcome to understand this phenomenon better and support preventive actions and treatment for puerperal women.

Early postoperative neurocognitive complications in elderly patients: comparing those with and without preexisting mild cognitive impairment- a prospective study.

BACKGROUND: As societies age, increasing numbers of older adults undergo surgeries with anesthesia. Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) frequently occur in older surgical patients. Most of these patients already have preoperative mild cognitive impairment (MCI). However, the correlation between MCI and POD remains unclear. This study aimed to determine the incidence of POD in elderly patients with and without preexisting MCI. METHODS: A prospective study enrolled patients aged 60 years and above scheduled for major surgeries between December 2017 and April 2022. Preoperative MCI was determined by a Montreal Cognitive Assessment (MoCA) score between 18 and 24. POD was diagnosed using criteria from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). POCD was characterized by a MoCA score reduction of 2 or more points from the preoperative score. The primary outcome was the incidence of POD within the first 72 h postoperatively. Secondary outcomes encompassed other postoperative complications, including POCD. RESULTS: The study comprised 223 elderly patients with MCI and 56 without MCI. The incidence of POD was 16.6% in the MCI group and 14.3% in the non-MCI group (P = 0.839). POCD occurred in 24.3% of MCI patients and 50% of non-MCI patients (P = 0.001). There were no significant differences in other postoperative complications between the groups. Postoperatively, the MCI group notably declined in visuospatial, attention, and orientation domains, while the non-MCI group declined in all domains except delayed recall. CONCLUSIONS: The incidence of POD was similar in the MCI and non-MCI groups. However, the non-MCI group demonstrated a higher incidence of POCD than the MCI group. This was identified by a reduction in postoperative MoCA scores for the visuospatial, naming, attention, language, abstraction, and orientation domains. These findings underscore the importance of postoperative cognitive assessments for both elderly patients with preexisting MCI and those with previously intact cognitive functions. TRIAL REGISTRATION: This trial was retrospectively registered in the Thai Clinical Trials Registry on 15/01/2019 (registration number: TCTR20190115001).
