Threat, Emotion Dysregulation, and Parenting in a Clinical Sample of Children with Disruptive Behaviour.

Early-life adversity is associated with the development of internalizing and externalizing problems in children. Despite this, there is a need to understand the mechanisms linking these experiences to psychopathology, especially in clinical samples. This cross-sectional study tested emotion dysregulation as a mechanism linking early-life threat to psychopathology in a clinical sample of children with disruptive behavior problems. We also explored parental positive reinforcement as a protective factor in these pathways. A clinical sample of 606 children aged 6-12 years, referred to a mental healthcare hospital, were included. Parent-reported child threat, and parent- and teacher-reported child emotion dysregulation and psychopathology, were collected. Path analysis was used to explore the mediating effect of emotion dysregulation in the relation between threat and psychopathology. The moderating effects of parental positive reinforcement were explored through moderated-mediation analyses. Emotion dysregulation partially mediated the association between threat and both internalizing (ß = .18, P = .006) and externalizing (ß = .19, P = .002) problems. Positive reinforcement did not buffer the association between threat and emotion dysregulation (ß = .09, P = .62) or the association between emotion dysregulation and internalizing (ß = - .003, P = .20) or externalizing (ß = - .002, P = .35). Poor emotion regulation may be a transdiagnostic mechanism linking early-threat with internalizing and externalizing problems in clinic-referred children with disruptive behaviors. Factors aside from parental positive reinforcement should be explored as protective factors in these pathways, including those directly implicated in the purported mechanisms linking these factors over time.

Psychometric properties of the Arabic translation of the Dark Future Scale questionnaire in a non-clinical sample of Arabic-speaking young adults.

BACKGROUND: Through the years, studying negative behaviors of the worldwide population seized the spotlight from many researchers who focused on building scales in order the measure the level of worries, fear and even depression of such stressed individuals. By definition, "Future anxiety" (FA) is fueled by negative thoughts leading to intense fear of unknown future events. The Dark Future scale (DFS) measures the level of anxiety experienced towards the future. Our aim was to examine the psychometric properties of a novel Arabic translation of the DFS. METHODS: A sample of 684 Arabic-speaking young adults (65.6% women) filled the DFS, TEMPS-M (temperaments) and DASS-8 (psychological distress). RESULTS: Confirmatory factor analyses (CFA) supported a unidimensional model of the DFS score, with all 5 items retained. This scale had good reliability. Moreover, concurrent validity demonstrated significant associations between DFS scores and psychological distress, depressive, cyclothymic, irritable and anxious temperament. Scores achieved scalar invariance across gender, with women having greater exposure to anxiety about the future. CONCLUSION: Overall, these findings led to the conclusion that the Arabic DFS is a psychometrically valid tool for the assessment of FA. The DFS is a brief, reliable and easy to apply scale that would help researchers in psychology and psychiatry in assessing anxiety about future.

Evaluation of the SARS-CoV-2 RNA detection reagent LAMPdirect Genelyzer KIT using nasopharyngeal swab and saliva samples.

The LAMPdirect Genelyzer KIT allows for the detection of SARS-CoV-2 RNA in saliva samples with a loop-mediated isothermal amplification (LAMP) method and generates results within 20 min. It has been approved by the Pharmaceuticals and Medical Devices Agency in Japan. In this study, the performance of the LAMPdirect Genelyzer KIT was compared with that of the RT-qPCR reference method using 50 nasopharyngeal swabs and 100 saliva samples. In addition, we evaluated the applicability of an alternative reverse transcriptase and the effects of an inactivation buffer. The total agreement rates were 80.0 % and 82.0 % for nasopharyngeal and saliva samples, respectively. When considering samples at the detection limit (50 copies/reaction) that increases the chance of transmission between humans, the total agreement rates were 100% and 94.1% for nasopharyngeal and saliva samples, respectively. The LAMP method is simple, fast, and inexpensive, making it useful for small medical institutions or rural areas.

Identifying Factors Associated with Bullying Roles Using the interRAI Child and Youth Mental Health (ChYMH) Suite of Instruments.

Bullying is a common problem amongst school-aged children and youth and is a significant concern for caregivers and teachers. interRAI is an international not-for-profit network of roughly 150 researchers and clinicians from over 35 countries. The main goal of interRAI is to develop and support standardized assessment systems for vulnerable individuals to support care planning, evidence-based clinical decision making, outcome measurement and quality assurance. This study aimed to examine factors associated with bullying roles in a large clinical sample (n = 26,069) using interRAI Child and Youth Mental Health assessments. Findings revealed children who both bullied peers and were victims of bullying (compared to those who were solely bullies, victims, or neither) were more likely to experience interpersonal traumas including witnessing domestic violence, physical and sexual assault; increased risk of self-harm and suicide, depression; more behavioural/externalizing problems; conflict within the school and home contexts; and higher levels of financial, familial, and living instability. The potential causes and implications of these distinctions are discussed. Findings can aid professionals in tailoring preventive measures that could more effectively minimize the incidence and effect of bullying.

An enzyme-free sensing platform for miRNA detection and in situ imaging in clinical samples based on DNAzyme cleavage-triggered catalytic hairpin assembly.

MicroRNA (miRNA) is demonstrated to be associated with the occurrence and development of various diseases including cancer. Currently, most miRNA detection methods are confined to in vitro detection and cannot obtain information on the temporal and spatial expression of miRNA in relevant tissues and cells. In this work, we established a novel enzyme-free method that can be applied to both in vitro detection and in situ imaging of miRNA by integrating DNAzyme and catalytic hairpin assembly (CHA) circuits. This developed CHA-Amplified DNAzyme miRNA (CHAzymi) detection system can realize the quantitively in vitro detection of miR-146b (the biomarker of papillary thyroid carcinoma, PTC) ranging from 25 fmol to 625 fmol. This strategy has also been successfully applied to in situ imaging of miR-146b both in human PTC cell TPC-1 and clinical samples, showing its capacity as an alternative diagnostic method for PTC. Furthermore, this CHAzymi system can be employed as a versatile sensing platform for various miRNAs by revising the relevant sequences. The results imply that this system may expand the modality of miRNA detection and show promise as a novel diagnostic tool in clinical settings, providing valuable insights for effective treatment and management of the disease.

Methylation-Specific Electrophoresis.

Methylation of CpG sites in the promoter region of genomic DNA is an important epigenetic modification that plays a critical role in gene regulation, particularly in gene silencing. Epigenetic abnormalities, along with genetic alterations, are implicated in carcinogenesis and cancer progression. Numerous studies have investigated the role of epigenetics in cancer using various tools to assess DNA methylation. However, conventional analysis methods for DNA methylation require a large amount of DNA but lack higher sensitivity, making them unsuitable for analysis of samples with high heterogeneity, such as tumor tissues. In this study, we introduce a novel electrophoresis method named "methylation-specific electrophoresis (MSE)," which utilizes a denaturing gradient acrylamide gel. We demonstrate the applicability of the MSE method for DNA methylation analysis of the mucin gene as an example.

Single-Cell Liquid Biopsy of Lung Cancer: Ultra-Simplified Efficient Enrichment of Circulating Tumor Cells and Hand-Held Fluorometer Portable Testing.

Herein, we propose a paper-based laboratory via enzyme-free nucleic acid amplification and nanomaterial-assisted cation exchange reactions (CERs) assisted single-cell-level analysis (PLACS). This method allowed for the rapid detection of mucin 1 and trace circulating tumor cells (CTCs) in the peripheral blood of lung cancer patients. Initially, an independently developed method requiring one centrifuge, two reagents (lymphocyte separation solution and erythrocyte lysate), and a three-step, 45 min sample pretreatment was employed. The core of the detection approach consisted of two competitive selective identifications: copper sulfide nanoparticles (CuS NPs) to C-Ag+-C and Ag+, and dual quantum dots (QDs) to Cu2+ and CuS NPs. To facilitate multimodal point-of-care testing (POCT), we integrated solution visualization, test strip length reading, and a self-developed hand-held fluorometer readout. These methods were detectable down to ag/mL of mucin 1 concentration and the single-cell level. Forty-seven clinical samples were assayed by fluorometer, yielding 94% (30/32) sensitivity and 100% (15/15) specificity with an area under the curve (AUC) of 0.945. Nine and 15 samples were retested by a test strip and hand-held fluorometer, respectively, with an AUC of 0.95. All test results were consistent with the clinical imaging and the folate receptor (FR)-PCR kit findings, supporting its potential in early diagnosis and postoperative monitoring.

Near-Infrared Fluorescence Probe for Indication of the Pathological Stages of Wound Healing Process and Its Clinical Application.

Chronic wound healing is one of the most complicated biological processes in human life, which is also a serious challenge for human health. During the healing process, multiple biological pathways are activated, and various kinds of reactive oxygen species participate in this process. Hydrogen peroxide (H2O2) involves in chronic wounds and its concentration is fluctuated in different pathological stages during the wound healing process. Therefore, H2O2 may be recognized as a powerful biomarker to indicate the wound healing process. However, the pathological roles of H2O2 cannot be fully understood yet. Herein, we proposed a near-infrared fluorescent probe DCM-H2O2 for highly sensitive and rapid detection of H2O2 in living cells and scald and incision wound mice models. DCM-H2O2 exhibited a low detection limit and high specificity with low cytotoxicity for H2O2, which had great potential for its application in vivo. The probe was successfully utilized to monitor the fluctuation of endogenous H2O2 in the proliferation process of human immortalized epidermal (HACAT) cells, which confirmed that H2O2 participated in the cells' proliferation activity through a growth factor signaling pathway. In the scald and incision wound mice models, H2O2 concentration fluctuations at different pathological stages during the wound healing process could be obtained by in vivo fluorescence imaging. Finally, H2O2 concentrations in different stages of human diabetic foot tissues were also confirmed by the proposed probe. We expect that H2O2 could be a sensitive biomarker to indicate the wound healing process.

Measurement Invariance of the WISC-V across a Clinical Sample of Children and Adolescents with ADHD and a Matched Control Group.

Measurement invariance of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) 10-primary subtest battery was analyzed across a group of children and adolescents with ADHD (n = 91) and a control group (n = 91) matched by sex, age, migration background, and parental education or type of school. First, confirmatory factor analyses (CFAs) were performed to establish the model fit for the WISC-V second-order five-factor model in each group. A sufficiently good fit of the model was found for the data in both groups. Subsequently, multigroup confirmatory factor analyses (MGCFAs) were conducted to test for measurement invariance across the ADHD and control group. Results of these analyses indicated configural and metric invariance but did not support full scalar invariance. However, after relaxing equality constraints on the Vocabulary (VC), Digit Span (DS), Coding (CD), Symbol Search (SS), and Picture Span (PS) subtest intercepts as well as on the intercepts of the first-order factors Working Memory (WM) and Processing Speed (PS), partial scalar invariance could be obtained. Furthermore, model-based reliability coefficients indicated that the WISC-V provides a more precise measurement of general intelligence (e.g., represented by the Full-Scale IQ, FSIQ) than it does for cognitive subdomains (e.g., represented by the WISC-V indexes). Group comparisons revealed that the ADHD group scored significantly lower than the control group on four primary subtests, thus achieving significantly lower scores on the corresponding primary indexes and the FSIQ. Given that measurement invariance across the ADHD and the control group could not be fully confirmed for the German WISC-V, clinical interpretations based on the WISC-V primary indexes are limited and should only be made with great caution regarding the cognitive profiles of children and adolescents with ADHD.

Biomolecules-mediated electrochemical signals of Cu2+: Y-DNA nanomachines enable homogeneous rapid one-step assay of lung cancer circulating tumor cells.

This study presents a straightforward efficient technique for extracting circulating tumor cells (CTCs) and a rapid one-step electrochemical method (45 min) for detecting lung cancer A549 cells based on the specific recognition of mucin 1 using aptamers and the modulation of Cu2+ electrochemical signals by biomolecules. The CTCs separation and enrichment process can be completed within 45 min using lymphocyte separation solution (LSS), erythrocyte lysis solution (ELS), and three centrifugations. Besides, the influence of various biomolecules on Cu2+ electrochemical signals is comprehensively discussed, with DNA nanospheres selected as the medium. Three single-stranded DNA sequences were hybridized to form Y-shaped DNA (Y-DNA), creating DNA nanospheres. Upon specific capture of mucin 1 by the aptamer, most DNA nanospheres could form complexes with Cu2+ (DNA nanosphere-Cu2+), significantly reducing the concentration of free Cu2+. Our approach yielded the limit of detection (LOD) of 2 ag/mL for mucin 1 and 1 cell/mL for A549 cells. 39 clinical blood samples were used for further validation, yielding results closely correlated with pathological, computed tomography (CT) scan findings and folate receptor-polymerase chain reaction (FR-PCR) kits. The receiver operating characteristic (ROC) curve displayed an area under the curve (AUC) value of 0.960, demonstrating 100% specificity and 93.1% sensitivity for the assay. Taken together, our findings indicate that this straightforward and efficient pretreatment and rapid, highly sensitive electrochemical assay holds great promise for liquid biopsy-based tumor detection using CTCs.

Enrichment of SARS-CoV-2 sequence from nasopharyngeal swabs whilst identifying the nasal microbiome.

Simultaneously characterising the genomic information of coronaviruses and the underlying nasal microbiome from a single clinical sample would help characterise infection and disease. Metatranscriptomic approaches can be used to sequence SARS-CoV-2 (and other coronaviruses) and identify mRNAs associated with active transcription in the nasal microbiome. However, given the large sequence background, unenriched metatranscriptomic approaches often do not sequence SARS-CoV-2 to sufficient read and coverage depth to obtain a consensus genome, especially with moderate and low viral loads from clinical samples. In this study, various enrichment methods were assessed to detect SARS-CoV-2, identify lineages and define the nasal microbiome. The methods were underpinned by Oxford Nanopore long-read sequencing and variations of sequence independent single primer amplification (SISPA). The utility of the method(s) was also validated on samples from patients infected seasonal coronaviruses. The feasibility of profiling the nasal microbiome using these enrichment methods was explored. The findings shed light on the performance of different enrichment strategies and their applicability in characterising the composition of the nasal microbiome.

Disordered eating in transgender and gender non-conforming youth: A comparison to community-based and clinical samples.

OBJECTIVE: This study investigates eating pathology in transgender and gender non-conforming (TGNC) youth compared to a community-based sample and individuals with eating disorders (EDs). METHOD: Participants (ages 13-21 years) included TGNC youth from a paediatric gender clinic (N = 97), a demographically matched community-based sample of cisgender males (N = 97) and cisgender females (N = 97), and treatment-seeking patients with EDs (N = 112). The Eating Disorder Examination Questionnaire (EDE-Q) was used to assess ED cognitions and behaviours. RESULTS: Transgender and gender non-conforming participants reported significantly higher EDE-Q global scores compared to the cisgender samples, but significantly lower than the ED sample. Transgender and gender non-conforming individuals reported a higher likelihood of objective binge episodes (OBEs) than the cisgender groups, albeit lower than youth with EDs. A substantial proportion of TGNC participants scored in elevated ranges on the EDE-Q global score (35% ≥ score of 3, 17% ≥ score of 4), significantly higher than cisgender males (0% ≥ score of 3, 0% ≥ score of 4) and females (9% ≥ score of 3, 3% ≥ score of 4). CONCLUSIONS: Findings indicate that TGNC youth exhibit increased ED cognitions and OBEs compared to cisgender samples, highlighting the need for screening and addressing ED symptoms in this population.

Controllable self-assembled DNA nanomachine enable homogeneous rapid electrochemical one-pot assay of lung cancer circulating tumor cells.

A homogeneous rapid (45 min) one-pot electrochemical (EC) aptasensor was established to quantitatively detect circulating tumor cells (CTCs) in lung cancer patients using mucin 1 as a marker. The core of this study is that the three single-stranded DNA (Y1, Y2, and Y3) could be hybridized to form Y-shaped DNA (Y-DNA) and further self-assemble to form DNA nanosphere. The aptamer of mucin 1 could be complementary and paired with Y1, thus disrupting the conformation of the DNA nanosphere. When mucin 1 was present, the aptamer combined specifically with mucin 1, thus preserving the DNA nanosphere structure. Methylene blue (MB) acted as a signal reporter, which could be embedded between two base pairs in the DNA nanosphere to form a DNA nanosphere-MB complex, reducing free MB and resulting in a lower electrochemical signal. The results demonstrated that the linear ranges for mucin 1 and A549 cells were 1 ag/mL-1 fg/mL and 1-100 cells/mL, respectively, with minimum detectable concentrations were 1 ag/mL and 1 cell/mL, respectively. The quantitative analysis of CTCs in 44 clinical blood samples was performed, and the results were consistent with the computerized tomography (CT) images, pathological findings and folate receptor-polymerase chain reaction (FR-PCR) kits. The receiver operating characteristic (ROC) curve exhibited an area under the curve (AUC) value of 0.970. The assay revealed 100% specificity and 94.1% sensitivity. It is believed that this electrochemical aptasensor could provide a new approach to detect CTCs.

Highly-efficient selection of aptamers for detecting various HPV subtypes in clinical samples.

Nucleic acid aptamers are of great potentials in diagnostic and therapeutic applications because of their unique molecular recognition capabilities. However, satisfactory aptamers with high affinity and specificity are still in short supply. Herein, we have developed new selection methods allowing the free interactions between the targets and potential aptamers in solution. In our selection system, the protein targets (biotinylated randomly or site-specifically) were first incubated with the random DNA library, followed by the pull-down with the streptavidin magnetic beads or biolayer-interferometry (BLI) sensors. By comparing the two biotinylation strategies (random or site-specific) and two states of the targets (free or immobilized), we have found that the combination of the site-specific biotinylation and free-target strategies was most successful. Based on these highly-efficient selection strategies, HPV L1 aptamers were obtained. By designing the sandwich aptasensor assisted with RCA and CRISPR/Cas12a, we have diagnosed various HPV subtypes in clinical samples, such as easily-collected urine samples. In summary, our new strategy can allow efficient selection of aptamers with high affinity and specificity for clinical applications.

Evaluating the Interrater Reliability of the Icelandic Version of K-SADS-PL DSM-5.

The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL) is a valuable tool for diagnosing mental disorders in children and adolescents. Previous studies have examined its interrater reliability, but there is limited information on individual disorders, on the updated DSM-5 version. This study aims to analyse the interrater reliability of the Icelandic translation of K-SADS-PL, DSM-5 version. K-SADS-PL was administered to a clinical sample of outpatients from the Icelandic Anxiety Centre for Children, Adolescents, and Young Adults, and The Department of Child and Adolescent Psychiatry at Landspítali, the National University Hospital in Reykjavík, Iceland. In total, 135 patients aged 6-18 were included in this study. We assessed the interrater reliability using Cohen's κ, with results ranging from poor to excellent (0.3-1.0), though most disorders showed excellent reliability (κ > 0.75). The Icelandic translation of the DSM-5 K-SADS-PL is generally reliable when used by properly trained post-graduate students, which supports its use in clinical settings.

DSM-5 self-rated level 1 cross-cutting symptom measure (CCSM1): Proposal for a three-factors model and implications for the assessment of at-risk situations.

OBJECTIVE: The aim of this paper is to study the measurement of the DSM5 self-rated transversal symptoms level 1 (CCSM1) from a dimensional perspective in line with current models of psychopathology in three factors: internalization, thought disorders, externalization. METHOD: Based on the 670 non-clinical protocols we collected, we verified that the VSS is composed of three factors. We studied the 3-factor composition with half of the sample and confirmed this composition with the other half. To show that these three factors were more relevant than the original 13 dimensions, we compared the results to three clinical groups and, after a cluster analysis, we investigated the intensity and frequency of people at risk across the original dimensions. RESULTS: While the 13 initial dimensions of the CCSM1 do not completely differentiate this sample from the clinical groups, the three high-order dimensions are discriminating. Clustering confirms these results when comparing the least and most affected subjects and allows us to see that these three HODs have significant impacts on the observation of cases at risk of clinical disorders in this non-clinical sample. DISCUSSION: To be further validated, these three HODs should be studied in relation to tools that assess internalization, thought disorders or externalization.

Assessment of Hazardous Gaming in children and its dissimilarities and overlaps with Internet Gaming Disorder.

Background and aims: Children have been vastly overlooked in Internet Gaming Disorder (IGD) and Hazardous Gaming research so far. The diagnoses are listed in different ICD-11 chapters (addiction vs. problematic health condition) and are thus considered as distinct constructs. However, screening tools for children do not exist yet. We aimed to investigate the psychometric properties of an existing IGD screening tool modified to also assess Hazardous Gaming in children. Further, we aimed to compare the dissimilarity and overlap between (subclinical) IGD and Hazardous Gaming in children. Methods: The study analyzed data from a mixed school and clinical sample. Data from N = 871 children aged between 8 and 12 years of age (M = 10.3, SD = 0.90) were analyzed. Data were collected via the Video Game Dependency Scale (CSAS) in its parent report version, which was adapted to assess Hazardous Gaming symptoms in addition to the IGD symptoms. Item analyses and reliability and factor analyses were conducted on the Hazardous Gaming version. Results: The results show that the adapted CSAS version that assesses Hazardous Gaming symptoms in children mostly shows acceptable psychometric properties. Explorative Factor Analysis (EFA) shows a two-factor structure with one factor of higher order. Additionally, results show that 35.2% of all children meeting the threshold for Hazardous Gaming exclusively meet criteria for Hazardous Gaming but not for (subclinical) IGD. Vice versa, 91.3% of children with IGD also meet the criteria for Hazardous Gaming. Discussion: Hazardous Gaming and (subclinical) IGD are distinct constructs with some overlaps and might have a temporal relation. We recommend adding four items to assess Hazardous Gaming using the CSAS and further evaluate the validity. The assessment of Hazardous Gaming in children is crucial because it might occur earlier than subclinical or full-syndrome IGD.

MRI white matter hyperintensities and neuropsychological performance in a clinical sample.

OBJECTIVE: White-matter hyperintensities (WMH) are commonly observed on MRI of non-demented patients. Findings are mixed regarding their association with neuropsychological test performance. The purpose of this study is to investigate the association of white-matter hyperintensities on routine clinical MRI and neuropsychological test performance in non-demented outpatients. METHOD: Two groups were selected based on MRI results: (1) normal (n = 62, Mage = 50.21, Medu = 14.89) and (2) WMH without other MRI abnormality (n = 56, Mage = 55.43, Medu = 14.04). Neuropsychological tests assessed five cognitive domains for which index scores were calculated and categorized in the following clinical ranges: well below average, below average, low average, average, and above average. RESULTS: Likelihood ratios comparing base rates for the WMH and normal groups across these clinical ranges revealed significant base rate differences only for attention/processing speed (Lχ2 = 16.47, df = 4, p < .01), with more WMH patients in the below average range and fewer above average. Odds ratios were calculated using two z-score cutoffs: -1.67 and -1.00. While patients with WMH were significantly more likely to have an index z-score ≤ -1.00 on attention/processing speed tests (OR = 3.62, 95% CI: 1.08-12.19) and an executive function test of reasoning (OR = 4.63, 95% CI: 1.18-18.19), there was no difference in the likelihood the groups would have a z-score ≤ -1.67 in any cognitive domain. CONCLUSIONS: Taken together, these findings indicate that among referred outpatients without dementia, WMH on routine clinical MRI are associated with relatively mild decreased attention and processing speed.

CPA-Cas12a-based lateral flow strip for portable assay of Methicillin-resistant Staphylococcus aureus in clinical sample.

The rapid and accurate identification of methicillin-resistant Staphylococcus aureus at an early antibiotic therapy stage would be benefit to disease diagnosis and antibiotic selection. Herein, we integrated cross-priming amplification (CPA) and CRISPR/Cas 12a (designated as CPA-Cas 12a) systems to establish a sensitive and efficient lateral flow assay to detect methicillin-resistant Staphylococcus aureus. This assay relies on the CPA isothermal nucleic acid amplification strategy which can amplify the DNA extracted from Staphylococcus aureus and accompanying the indiscriminately trans-cleavage process of Cas 12a/CrRNA duplex after recognizing specific sequence. Taking the advantage of reporter and high turnover Cas 12a activity, a dramatic change in response was achieved to produce a significant increase in the analytical sensitivity. The signal conversion and output were realized using a lateral flow strip to achieve field-deployable detection. Furthermore, this bioassay was accommodated with a microfluidic device to realize automatically portable detection. This proposed assay completed within 30 min with the detection limit of 5 CFU mL-1, was verified by testing bacterial suspension and 202 clinical samples. Given the high sensitivity, specificity and efficiency, this colorimetric readout assay through strip could be further promoted to the clinical diagnosis, clinical medication of multidrug-resistant bacteria.

Reliability and Validity of the Elkins Hypnotizability Scale within a Clinical Sample.

Hypnotherapy is used in clinical settings to treat mental and physical health-related conditions. Hypnotic response can be measured through hypnotizability scales to help interventionists personalize treatment plans to suit the patients' individualized hypnotic abilities. Examples of these scales are the Elkins Hypnotizability Scale (EHS) and the Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C). According to the previous literature, these scales have good discriminating ability and internal consistency (α = 0.85) in collegiate samples, but the psychometric properties of the EHS for a targeted clinical population have not been determined yet. This study assessed said properties, and results showed adequate reliability of the EHS in a targeted clinical sample and strong convergent validity of the EHS to the SHSS:C. The authors conclude that the EHS is a strong and useful measure of hypnotizability that is pleasant, safe, brief, and sensible to individualities in hypnotic ability found in diverse clinical samples.
