Assessing how individuals conceptualize numeric pain ratings: validity and reliability of the Pain Schema Inventory (PSI-6) Short Form.

While numeric scales to represent pain intensity have been well validated, individuals use various conceptualizations when assigning a number to pain intensity, referred to as pain rating schema. The 18-item Pain Schema Inventory (PSI-18) quantifies pain rating schema by asking for numeric values for multiple mild, moderate or severe pain conditions. This study aimed to assess the validity and reliability of a shortened form of the PSI, using only 6 items (PSI-6). A secondary analysis was performed on two existing datasets. The first (n = 641) involved a community-based population that completed the PSI-18. The second (n = 182) included participants with chronic pain who completed the PSI-6 twice, one week apart. We assessed face validity, convergent validity, offset biases, test-retest reliability, and internal consistency of the PSI-6 compared to the PSI-18. Both the PSI-18 and PSI-6 demonstrated excellent face validity. The PSI-6 demonstrated excellent convergent validity relative to the PSI-18, with correlations from r = 0.88 to 0.92. Bland-Altman plots revealed offset biases near zero (< 0.22 on 0-10 scale) across all categories of mild, moderate, severe and average pain. Internal consistency was excellent, with Cronbach's Alpha = 0.91 and 0.80, for PSI-18 and PSI-6 respectively. Test-retest reliability of the PSI-6 was high with correlations from r = 0.70-0.76. The PSI-6 is a valid and reliable tool to assess pain rating schema with reduced subject burden, to better interpret individuals' pain ratings and adjust for inter-individual variability.

Development of the Southampton Experiential Avoidance and Acceptance Scale (SEAAS)

Acceptance is an important construct in various psychological models seeking to describe psychological distress and emotion regulation. Existing measures either focus on broader constructs like psychological flexibility or lack proper validation. There are no established tools which measure acceptance as a general process, as defined within Acceptance and Commitment Therapy (ACT). The absence of valid and reliable measures impedes research on acceptance processes in clinical change. To address this, we developed the Southampton Experiential Avoidance and Acceptance Scale (SEAAS). Across four studies an item pool was generated, evaluated, and refined into an 18-item scale with a theoretically coherent two-factor structure. The SEASS demonstrates strong psychometric properties, including excellent internal consistency, convergent, concurrent, and discriminant validity, and test-retest reliability. This scale is a promising new tool for assessing acceptance and experiential avoidance.

Exploring Compersion: A Study on Polish Consensually Non-Monogamous Individuals and Adaptation of the COMPERSe Questionnaire.

Compersion is a positive emotion experienced in relation to one's partner's relationship(s) with other partner(s). Experiencing it is highly desired in communities practicing consensual non-monogamy (CNM), especially polyamory. This article presents the results of a study on compersion on Polish CNM individuals. The main goal of the study was to adapt to the Polish-speaking population the COMPERSe (Classifying Our Metamour/Partner Emotional Response Scale; Flicker et al., 2021), the first standardized quantitative scale designed to measure compersion. The analyses were performed on data obtained from 211 individuals in CNM relationships and on a comparative group of 169 people in monogamous relationships. The results of the confirmatory factor analyses suggested that the three-factor model of the original COMPERSe version did not fit well, leading to further revisions that resulted in a 7-item, two-factor solution with excellent fit, excellent internal consistency, strong divergent and convergent validity, and excellent test-retest stability. The CNM individuals were found to have higher scores on compersion and cognitive empathy and were also less jealous than the monogamous participants. Furthermore, polyamorous individuals experienced more compersion and less aversion to partner's autonomy than people in open relationships. It was also revealed that compersion indirectly predicted relationship satisfaction by decreasing jealousy and that compersion was, in turn, predicted by cognitive empathy. However, when polyamorous and open relationships were analyzed separately, compersion predicted relationship satisfaction directly, but only in polyamorous relationships; meanwhile, in open relationships, satisfaction was directly predicted by cognitive empathy.

Adaptation and validation of Arabic version of the screening tool of feeding problems applied to children (STEP-CHILD)

Objectives Early identification of pediatric feeding problems is crucial to preventing their subsequent negative impact on children's quality of life. This study aimed to create and validate an Arabic-modified version of the Screening Tool of Feeding Problems Applied to Children (STEP-CHILD) to identify feeding problems in Arabic-speaking children. Methods The STEP-CHILD Arabic was created and administered to the parents/caregivers of 390 Arabic-speaking children aged 2-18 years. 89 typically developing children without feeding/swallowing problems and 301 children with developmental disabilities were included in the study. The data was statistically analyzed to examine the validity and reliability of the questionnaire. Results The STEP-CHILD Arabic demonstrated excellent content validity, face validity, discriminant validity, and convergent validity. Predictive validity showed that the questionnaire has moderate to high accuracy in identifying pediatric feeding problems. It also showed excellent reliability and allowed for determining the specific feeding problems that would be targeted in the intervention. Conclusions The STEP-CHILD Arabic is a valid, reliable, and easily applicable tool that can be used as a routine evaluation for Arabic-speaking children at high risk of feeding problems.

Psychometric Evaluation of the Chinese Version of the Family Accommodation Scale for Obsessive–Compulsive Disorder Patient Version

This study aimed to examine the psychometric properties of the Chinese version of the family accommodation scale for obsessive–compulsive disorder (OCD) patient version (FAS-PV). A total of 171 adult OCD patients and 145 family members were enrolled in the present study. The majority of the adult OCD patients (89.5%) reported engaging in at least one accommodating behavior in the past week. The FAS-PV comprised three components that included (a) direct participation and facilitation, (b) provision of reassurance and assumption, and (c) modification of routines and avoidance. The FAS-PV demonstrated excellent internal consistency. The correlation between the total FAS-PV score and the criteria measure demonstrated excellent convergent validity when assessing the OCD symptom severity, global functioning, family functioning, and functioning impairment. The findings supported that the FAS-PV could be used widely in evaluating and identifying the accommodating behavior both in clinical and in research settings, especially in adult OCD patients who usually present to the clinic alone.

Development and validation of the Cannabis Exposure in Pregnancy Tool (CEPT): a mixed methods study

BackgroundEvidence of associations between prenatal cannabis use (PCU) and maternal and infant health outcomes remains conflicting amid broad legalization of cannabis across Canada and 40 American states. A critical limitation of existing evidence lies in the non-standardized and crude measurement of prenatal cannabis use (PCU), resulting in high risk of misclassification bias. We developed a standardized tool to comprehensively measure prenatal cannabis use in pregnant populations for research purposes.MethodsWe conducted a mixed-methods, patient-oriented tool development and validation study, using a bias-minimizing process. Following an environmental scan and critical appraisal of existing prenatal substance use tools, we recruited pregnant participants via targeted social media advertising and obstetric clinics in Alberta, Canada. We conducted individual in-depth interviews and cognitive interviewing in separate sub-samples, to develop and refine our tool. We assessed convergent and discriminant validity internal consistency and 3-month test–retest reliability, and validated the tool externally against urine-THC bioassays.ResultsTwo hundred fifty four pregnant women participated. The 9-item Cannabis Exposure in Pregnancy Tool (CEPT) had excellent discriminant (Cohen’s kappa = -0.27–0.15) and convergent (Cohen’s kappa = 0.72–1.0) validity; as well as high internal consistency (Chronbach’s alpha = 0.92), and very good test–retest reliability (weighted Kappa = 0.92, 95% C.I. [0.86–0.97]). The CEPT is valid against urine THC bioassay (sensitivity = 100%, specificity = 82%).ConclusionThe CEPT is a novel, valid and reliable measure of frequency, timing, dose, and mode of PCU, in a contemporary sample of pregnant women. Using CEPT (compared to non-standardized tools) can improve measurement accuracy, and thus the quality of research examining PCU and maternal and child health outcomes.

Translation and validation of the Hungarian version of the Birth Satisfaction Scale-Revised (BSS-R)

BackgroundEvidence relating maternal birth experience to a range of maternal and neonatal outcomes is increasingly compelling. Consequently valid and reliable self-report of birth experience from the mothers perspective is critical. AimThe current study sought to translate and validate a Hungarian-language version of the Birth Satisfaction Scale-Revised (BSS-R). MethodFollowing forward and backwards translation into Hungarian, the Hungarian BSS-R (HU-BSS-R) was administered to women in a major Transylvanian hospital maternity unit within 72 h postpartum. Key psychometric characteristics were then examined in relation to factor structure, divergent and convergent validity, internal consistency, and known-groups discriminant validity. ResultsTwo-hundred and thirty-two women completed the HU-BSS-R. Confirmatory factor analysis revealed the HU-BSS-R to offer an excellent fit to data for the established tri-dimensional measurement model. The HU-BSS-R was also found to offer excellent convergent and divergent validity and known-groups discriminant validity. No significant differences were observed between internal consistency observations between the current study and the original UK validation study. ConclusionsThe HU-BSS-R is a valid and reliable translation of the original BSS-R, it has proved itself to have excellent psychometric properties and is suitable for use in the Hungarian maternity context.

Development and validation of an 8-item version of the Real Relationship Inventory–Client form

Objective: To develop and validate a very brief version of the 24-item Real Relationship Inventory–Client (RRI-C) form. Method: Two independent samples of individual psychotherapy patients (Nsample 1 = 700, Nsample 2 = 434) completed the RRI-C along with other measures. Psychometric scale shortening involved exploratory factor analysis, item response theory analysis, confirmatory factor analysis (CFA), and multigroup CFA. Reliability and convergent and discriminant validity of the scale and subscales were also assessed. Results: The 8-item RRI-C (RRI-C-SF) preserves the two-factor structure: Genuineness (k = 4, α = .86) and Realism (k = 4, α = .87), which were correlated at r = .74. CFA provided the following fit indices for the bifactor model: X 2/df = 2.16, CFI = .99, TLI = .96, RMSEA = .07, and SRMR = .03. Multigroup CFA showed that the RRI-C-SF was invariant across in-person and remote session formats. The RRI-C-SF demonstrated high reliability (α = .91); high correlation with the full-length scale (r = .96); and excellent convergent and discriminant validity with measures of other elements of the therapeutic relationship, personality characteristics, current mental health state, and demographic-clinical variables. Clinical change benchmarks were calculated to serve as valuable tools for both research and clinical practice. Conclusion: The RRI-C-SF is a reliable measure that can be used for both research and clinical purposes. It enables a nuanced assessment of the genuineness and the realism dimensions of the real relationship.

Evaluation of the German Version of the Keratoconus Outcomes Research Questionnaire.

To translate, validate, and evaluate the psychometric properties of the German version of Keratoconus Outcomes Research Questionnaire (KORQ). This prospective study included 3 phases. In phase 1, the KORQ was translated in a standardized way; in phase 2, Rasch validation was performed; in phase 3, the validated questionnaire was evaluated in a separate patient cohort. All patients answered the German KORQ. Scheimpflug imaging (Pentacam) and optical coherence tomography scans (MS-39) were conducted. Corneal imaging measurements were correlated with patient-reported outcome measures. After standardized translation, 100 patients self-administered the German KORQ. Rasch analysis was conducted for psychometric testing of the KORQ. Based on the results of the Rasch analysis, the original German version of the KORQ was modified and any items showing a misfit were excluded. This resulted in a new shortened version of the KORQ, which was evaluated in 30 patients. The revised German KORQ met the criteria of Rasch analysis and showed excellent internal consistency reliability and convergent validity. The correlation between the KORQ score and various clinical measurements was examined using Spearman correlation. A significant moderate correlation was observed between the D (r = 0.237; P = 0.006) and Kmax (r = 0.162; P = 0.065) values of Pentacam. Inverse correlations were observed for thinnest pachymetry measured with MS-39 (r = -0.167; P = 0.058) and best corrected visual acuity (r = -0.210; P = 0.016). The shortened German KORQ met the assumptions of the Rasch model and displayed satisfactory psychometric properties. The German KORQ could be adopted as a powerful patient-reported outcome measures tool for German-speaking patients with keratoconus in the future.

Enhancing Patient-Reported Outcome Measures for Drug Hypersensitivity: A Validated 6-Item Quality-of-Life Questionnaire for Patients With Drug Hypersensitivity

BACKGROUNDDrug hypersensitivity reactions (DHR) can significantly impair patients’ health-related quality of life (HRQoL). However, tools for HRQoL assessment for patients with DHR are time-consuming and remain underutilized. OBJECTIVETo develop and validate an optimized version of the Drug Hypersensitivity Quality of Life Questionnaire (DrHy-Q) designed for everyday clinical use. METHODSItem response theory (IRT), a statistical framework for psychometric measurement, was used to evaluate the 15 questions from the original DrHy-Q for their respective item difficulty, discrimination, and information using prospective data from 243 patients with histories of suspected/confirmed DHR before allergy workup. Accordingly, the best-performing items were identified to develop a 6-item optimized version (DrHy-Q6), which was subsequently validated with another prospective cohort of 156 patients. RESULTSAll 15 items of the original DrHy-Q demonstrated satisfactory parameters in IRT analysis, including very high discrimination (>1.7), appropriate difficulty (in between -1.5 and 1.5) and good information (a high and broad peak in the information curve). Six items with top-ranked IRT parameters were identified to construct an optimized version, which we named the DrHy-Q6. The DrHy-Q6 demonstrated a 1-factor structure with an improved fit compared to the original DrHy-Q (comparative fit index = 0.985, Tucker–Lewis’s index = 0.974), excellent convergent validity (Unadjusted Pearson correlation with the full version = 0.955; adjusted = 0.894, p<0.001), reliability (Cronbach’s α and McDonald’s ω = 0.93), divergent validity (Pearson correlation with all Short Form 12-item Healthy Survey Version 2 [SF-12v2] subscales < 0.60, p<0.001) and discriminant validity (significantly higher scores with multiple DHR labels [42.45 ± 27.26 vs. 32.93 ± 26.66], p=0.013). CONCLUSIONSFrom an IRT perspective, the DrHy-Q and all its constituent items are psychometrically valid for HRQoL assessment. We propose an optimized 6-item version (DrHy-Q6) as an abbreviated alternative for assessing HRQoL in patients with DHR, especially for routine use in clinical practice. Patients and physicians may benefit from its streamlined length and simpler scoring algorithm.

Design and validation of the classroom climate for an inclusive education questionnaire (CCIEQ)

This study aims to validate the Classroom Climate for an Inclusive Education Questionnaire (CCIEQ) to assess the quality of the conditions for inclusive teaching performance through three different procedures. Firstly, the study aims to evaluate the questionnaire’s content validity, culminating in the selection of nine theoretically dimensions validated quantitatively by means of an adequate Minimum Discrepancy of the Chi-square Value Divided by Degree of Freedom Index (CMIN/DF). Secondly, it seeks to assess the construct validity of the questionnaire with a Robust Exploratory Factor Analysis Technique and Hull Method to evaluate internal consistency for a final configuration of a single factor to obtain a single final score. Thirdly, the study aims to evaluate the questionnaire’s convergent validity, showing the existing correlations with other instruments previously validated for the same purpose (CEFI-R, UDL-checklist Test) using a common participant sample. To achieve these objectives, a sample of 153 in service teachers was used, recruited for the study sample from four different countries (Spain, Turkey, Latvia and Poland) through cluster sampling. The results show excellent psychometric properties and convergent validity of the CCIEQ, so its use as a scientific tool for samples of European in-service teachers is validated.

Translation and Psychometric Evaluation of a Chinese Version of the Behavioral Regulation in Sport Questionnaire (BRSQ) with University Sport Athletes.

Our aim in this study was to translate and psychometrically evaluate a Chinese version of the Behavioral Regulation in Sport Questionnaire (BRSQ). Participants were Chinese collegiate athletes (N = 361) who were competitive in their respective sports. We examined the construct validity of the Chinese BRSQ using alternative structural equation models and evaluated convergent validity, factor score reliability, and measurement invariance of the optimal model. Due to insufficient score reliability for some subscales, our initial Chinese BRSQ was deemed problematic. A modified version of the questionnaire with a four-factor structure (amotivation, external regulation, introjected regulation, and autonomous motivation) demonstrated excellent construct validity, convergent validity, and score reliability. There was measurement invariance across athlete level and sex. This tool provides a valuable resource for practitioners and sport psychology researchers for assessing sport motivation among competitive university athletes in China.

The development and initial validation of the Trauma-Related Alcohol Use Coping Measure (TRAC).

Posttraumatic stress disorder (PTSD) symptoms and alcohol use commonly co-occur and present a prevalent clinical comorbidity. The self-medication/coping model has been applied most consistently to understand the PTSD-alcohol use association. However, there is a relative paucity of self-report measures designed to assess motivations for alcohol use, specifically for coping with PTSD symptoms. The goals of the present study were to develop and validate a measure that assesses the use of alcohol to cope with specific facets of PTSD symptomatology across two independent samples. Two samples were evaluated: a university-based sample (N = 617; 77.0% women; Mage = 22.3; SD = 5.20) composed of racially diverse trauma-exposed students and a nationally representative sample (N = 510; 52.5% women; Mage = 39.5; SD = 10.9) of trauma-exposed adults who endorsed PTSD symptoms and past-year hazardous drinking. Both samples completed identical online questionnaire batteries. A Trauma-Related Alcohol Use Coping (TRAC) measure was developed and validated across both samples. Confirmatory factor analysis was used to support the latent, hierarchical structure of the TRAC measure (total score; coping with intrusion, avoidance, negative alterations in cognitions and mood, and arousal/reactivity symptoms) and supported an 18-item version of the TRAC measure (university-based sample [N = 617]: RMSEA = 0.047, 90% CI [.04, .05]; SRMR = 0.043; CFI = 0.95; TLI = 0.95; nationally representative sample [N = 510]: RMSEA = 0.045, 90% CI [.04, .05]; SRMR = 0.021; CFI = 0.98; TLI = 0.97). The TRAC measure demonstrated excellent internal consistency, convergent, and discriminant validity with well-established measures of mental health, known-groups validity, and incremental validity relative to non-PTSD coping-motivated drinking. Overall, the TRAC measure can be used to assess the extent to which alcohol use is related to coping with PTSD symptoms. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Development of the Enthusiastic Substance Use Attitudes Scale: Preliminary Evidence of a Novel Maintenance Factor

Background: Expectancies, motives, and attitudes toward substances are cognitive factors that partially account for substance use; however, existing measures tend to have monotonous phrasing, diverging from the enthusiastic attitude toward the perceived benefits of substance use exhibited by those who use substances regularly in informal settings. Objective: I aimed to characterize a new cognitive maintenance factor that precedes substance use by creating a brief, multidimensional measure to capture this tone nuance, which I called the Enthusiastic Substance Use Attitudes Scale (ESUAS). Method: Undergraduate students (n = 198) between ages 18 and 62 (M = 19.15, SD = 3.65; 66.2% women; 71.71% White) completed the study for course credit. Results: I used exploratory and confirmatory factor analyses to reduce a 90-item item pool based on a comprehensive qualitative thematic analysis of social media, traditional media, and the scientific literature to an 18-item hierarchical bifactor model. This model contained nine specific factors, which are (1) sociability, (2) enjoyment, (3) physical health, (4) mental health, (5) relaxation, (6) personal growth, (7) performance enhancement, (8) boredom, and (9) life processing; two general factors, which are (1) substance-induced emotion regulation and (2) substance-based assistance; and a higher-order single factor above the nine specific factors – resulting in twelve highly internally consistent, empirically supported scales. Further, the ESUAS demonstrated excellent structural, convergent, divergent, incremental, and diagnostic validity. The degree of enthusiasm towards substance use positively related to substance use disorder symptomology, polysubstance use, neuroticism, and difficulty with regulating emotions while negatively relating to one’s psychological quality of life and agreeableness. Conclusion: The ESUAS may be an effective tool for professionals to characterize these enthusiastic attitudes further and measure a more ecologically valid view of the perceived benefits of substance use among those who use substances, thereby developing a more compassionate, non-stigmatizing understanding within the general public, advancing medicinal uses of illicit substances, and improving conceptualizations and treatments.

Cross-cultural adaptation and validation of Injustice Experience Questionnaire in Greek

Purpose The Injustice Experience Questionnaire (IEQ) gauges the extent to which individuals with chronic pain perceive feelings of injustice concerning their pain. The study’s objective was to assess the feasibility, absolute and relative reliability, as well as the convergent and construct validity of the Greek version of the IEQ. Methods A cross-cultural adaptation of the IEQ in Greek was carried out according to the published guidelines. Ninety patients with chronic pain and 44 healthy participants completed the IEQ-GR, the Pain Catastrophizing Scale (PCS), and the Hospital Anxiety and Depression Scale (HADS). A subset of 36 volunteers completed the IEQ-GR twice over 1 week. Results The ICC was calculated at 0.98 for IEQ-total and 0.83–0.96 for all items. The Cronbach’s a was estimated at 0.98 for IEQ-total and 0.91–0.98 for all items. The SEM ranged from 0.20 to 1.63 and the SDC was 0.36–2.62 for all items. Positive and significant correlations between IEQ-GR and PCS (r = 0.59, p < 0.01), HADS (r = 0.58, p < 0.01), HADS depression (r = 0.50, p < 0.01), and HADS anxiety (r = 0.55, p < 0.01), were found. There was a statistically significant difference in IEQ between the patient and control groups. Conclusions The IEQ-GR demonstrated excellent reliability, internal consistency, convergent and discriminant validity in a Greek population.

Psychometric evaluation of the depression, anxiety, and stress scale-21 (DASS-21) among Chinese primary and middle school teachers

BackgroundTeachers in high-stress roles face increasing psychological distress such as anxiety and depression, underscoring the need for validated assessment instruments. Given the current absence of a comprehensive, designated, and time-efficient scale capable of evaluating depression, anxiety, and stress among the teacher population, the Depression, Anxiety, and Stress Scale-21 (DASS-21) presents itself as a promising alternative. Despite the widespread application of the DASS-21 for assessing psychological distress across various populations, its validity among teachers, along with questions about its factor structure and its potential property of time equivalence, remain unverified. This study endeavors to address these considerations by investigating the psychometric properties of the DASS-21 specifically within the population of Chinese primary and middle school teachers.MethodsCross-sectional (n = 9,030) and longitudinal surveys (n = 1,642) were conducted using a non-probability sampling method. In addition to the DASS-21, the Chinese version of Chinese Teachers’ Job Burnout Questionnaire (CTJBO) was utilized to evaluate the criterion validity of this scale. Three different approaches, namely confirmatory factor analysis, Rasch analysis, and network analysis, were employed to evaluate internal reliability, construct validity, as well as time invariance of the DASS-21.ResultsThe DASS-21 demonstrated a high degree of internal consistency (Cronbach’s α > 0.85) as well as excellent convergent validity, despite poor discriminant validity as determined by average variance extracted. Confirmatory factor analysis and network analysis further supported convergent validity. The three-factor structure outperformed one- and two-factor alternatives, establishing time invariance. Rasch analysis at the item level identified six inappropriate items within the anxiety and stress subscales, which were subsequently removed. Network analysis presented a better revised network. Regression analysis with emotional exhaustion as the criterion provided logical and accurate results.ConclusionThe DASS-21 was found to be a reliable and valid tool for measuring the mental health of teachers over time. To assess the instrument’s psychometric properties, a combination of confirmatory factor analysis, Rasch analysis, and network analysis was utilized, which proved effective and is recommended for evaluating contentious instruments. Based on the results of the study, researchers and healthcare professionals are recommended to use the DASS-21 for assessing teachers’ psychological distress. However, certain items identified in the study may need to be removed to enhance the instrument’s appropriateness for this specific population.

Free to be me with you: Development of the Individuality in Couples Questionnaire.

Despite multiple theories and treatment modalities emphasizing the importance of individuality in couple relationships, the field is lacking a reliable and valid measure of this construct. In the present study, we developed the Individuality in Couples (ICQ) questionnaire and demonstrated its strong psychometric properties across two samples of participants in committed intimate relationships (Sample 1 = 580 undergraduates; Sample 2 = 445 community members). The ICQ is comprised of 25 items that can be combined into a reliable total score to measure individuality in the context of couple relationships (i.e., the extent to which someone feels respected by their partner for their individuality and experiences personal autonomy in the relationship). Scores on the ICQ demonstrated high internal consistency, excellent construct replicability, convergent and divergent validity with measures of other relationship dimensions (i.e., intimacy, support, sexual satisfaction, psychological aggression, communication), criterion validity with measures of relationship satisfaction and partner health, and incremental predictive validity for explaining relationship satisfaction and partner well-being when controlling for other relationship dimensions. Results suggest that individuality in couples is largely a unidimensional construct that is distinct from more severe patterns of control and coercion characteristic of psychological aggression. The ICQ holds promise for identifying and promoting dynamics essential for healthy couple relationships. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Measuring early life adversity in adults: French translation and validation of the Maltreatment and Abuse Chronology of Exposure (MACE) scale

In contrast to other tools used with adults to retrospectively assess exposure to early adversity, the Maltreatment and Abuse Chronology of Exposure (MACE) scale (Teicher & Parigger, 2015) investigates exposure to a wide range of adverse childhood experiences (ACEs). It also explores the timing and duration of this exposure, which has been shown to be important in identifying developmentally sensitive periods for exposure to childhood adversity. The main goal of this study was therefore to provide a French translation of the MACE and to assess its psychometric properties. An experimental group of N = 402 French adults (Mage = 39.1 ± 10.8 years) from the general population completed the French version of the 52-item MACE scale online, along with other questionnaires. Statistical analyses show that a 50-item version reliably captures exposure to the 10 types of ACEs investigated by the scale. The MACE scale exhibits excellent convergent validity with the Childhood Trauma Questionnaire (CTQ; Bernstein et al., 1994, 1997), and is more effective than the CTQ in predicting psychiatric morbidities such as dissociation and anxiety. Test-retest reliability was assessed online over a period of more than 12 months in a subgroup of 50 participants. Results show adequate test-retest reliability for both composite and subscale scores. Overall, the MACE-50 (Fr) comprehensively assesses exposure to early childhood adversity in adults, has acceptable psychometric properties, and is a reliable tool both for clinical practice and research.

Construct validity of the Hungarian Version of the Patient-Reported Outcomes Measurement Information System-29 Profile Among Patients with Low Back Pain

We aim to evaluate the psychometric properties of the Hungarian version of the patient-reported outcomes measurement information system (PROMIS)-29 profile domains among patients with chronic low back pain. We used a convenience, cross-sectional sampling of patients recruited at our neurosurgical institution. The participants completed paper-pencil version of the PROMIS-29 profile in addition to validated legacy questionnaires, including the Oswestry disability index, Research and Development Corporation 36-item short-form survey, 7-item general anxiety disorder scale, 9-item patient health questionnaire. Reliability was evaluated by calculating the internal consistency (Cronbach's α). Test-retest reliability was assessed using the intraclass correlation coefficient. The structural validity of PROMIS-29 was assessed using a confirmatory factor analysis. Construct validity was assessed by evaluating convergent and discriminant validity using Spearman's rank correlation. To further corroborate the construct validity, we also performed known-group comparisons. The mean age of the 131 participants was 54 ± 16 years. Of the 131 patients, 62% were women. The internal consistency of each PROMIS domain was high (Cronbach's α >0.89 for all). The test-retest reliability was excellent (intraclass correlation >0.97). The confirmatory factor analysis showed good structural validity (comparative fit index >0.96; standardized root mean square residual <0.026 for all domains). All measured PROMIS scores correlated strongly with the scores obtained using the corresponding primary legacy instrument, indicating excellent convergent validity. The known-group comparisons demonstrated differences as hypothesized. We present data supporting the validity and reliability of the Hungarian PROMIS-29 profile short forms for patients with low back pain. This instrument will be useful for research and clinical applications in spine care.

Development and Evaluation of a Pragmatic Measure of Adherence to Dialectical Behavior Therapy: The DBT Adherence Checklist for Individual Therapy.

This paper presents two studies conducted to develop and evaluate a new pragmatic measure of therapist adherence to Dialectical Behavior Therapy (DBT): the DBT Adherence Checklist for Individual Therapy (DBT AC-I). Study 1 used item response analysis to select items from the gold standard DBT Adherence Coding Scale (DBT ACS) using archival data from 1271 DBT sessions. Items were then iteratively refined based on feedback from 33 target end-users to ensure relevance, usability, and understandability. Study 2 examined the psychometric properties of the DBT AC-I as a therapist self-report and observer-rated measure in 100 sessions from 50 therapist-client dyads, while also evaluating predictors of therapist accuracy in self-rated adherence. When used as a therapist self-report measure, concordance between therapist and observer ratings was at least moderate (AC1 ≥ 0.41) for all DBT AC-I items but overall concordance (ICC = 0.09) as well as convergent (r = 0.05) and criterion validity (AUC = 0.54) with the DBT ACS were poor. Higher therapist accuracy was predicted by greater DBT knowledge and adherence as well as more severe client suicidal ideation. When used by trained observers, the DBT AC-I had excellent interrater reliability (ICC = 0.93), convergent validity (r = 0.90), and criterion validity (AUC = 0.94). While therapists' self-rated adherence on the DBT AC-I should not be assumed to reflect their actual adherence, some therapists may self-rate accurately. The DBT AC-I offers an effective and relatively efficient method of evaluating adherence to DBT when used by trained observers.
