The translation and validation of the surgical anxiety questionnaire into the modern standard Arabic language: results from classical test theory and item response theory analyses

BackgroundPreoperative anxiety is commonly found in patients who are waiting for surgery and can lead to negative surgical outcomes. Understanding the sources of surgical anxiety allows healthcare providers to identify at-risk patients and implement psychosocial interventions such as counseling, relaxation techniques, and cognitive‒behavioral therapy to minimize anxiety. Few comprehensive psychiatric measures are available to assess preoperative anxiety in Arabic.ObjectiveOur study aimed to translate, adapt, and validate the Surgical Anxiety Questionnaire (SAQ) into the modern standard Arabic language, also known as Fusha al-Asr Arabic.MethodsTo translate the questionnaire, the research team used the gold standard process of forward translation by two independent translators along with back translation evaluation by four trained medical doctors. A cross-sectional study was conducted using an online survey completed by 208 Arabic speakers (mean age 38 years, 44% women) from four countries. Psychometric analyses, which included internal consistency, test-retest reliability, convergent validity, confirmatory factor analysis, and item response analysis, were performed. Convergent validity tests were performed against the Generalized Anxiety Disorder 2-item Scale (GAD-2), Patient Health Questionnaire-4 (PHQ-2), Perceived Stress Scale 4 (PSS-4), and Arabic version of the Visual Analog Scale for anxiety (VAS-A).ResultsThe mean SAQ of our sample was 19.38 ± 12.63 (possible range 0–68). The Arabic SAQ translation demonstrated excellent internal consistency, with McDonald’s omega and a Cronbach’s alpha of approximately 0.90. The test-retest reliability was also high, with an intraclass coefficient of 0.94. The SAQ showed strong convergent validity against the GAD-2 (r = 0.94, p < 0.01). The SAQ also showed weak-moderate correlations with the PHQ-2 (r = 0.26, p < 0.01), PSS-4 (r = 43, p < 0.01), and VAS-A (r = 0.36, p < 0.01) scores. The original three-factor structure was supported by confirmatory factor analysis, confirming the original structure reported in the original English language version. The results for fitness indices showed acceptable preliminary results (CFI/TLI approximately 0.90), and deleting some items improved the model fit (CFI/TLI > 0.90, RMSEA < 0.08). We suggest retaining the original factorial solution until further validation studies can be conducted. The item response theory (IRT) results identified no items that were excessively difficult or subject to guessing. The multidimensional IRT provided evidence that the SAQ items form a multidimensional scale assessing surgical anxiety that fits the classical model reasonably well.ConclusionThe SAQ has demonstrated acceptable reliability and validity; thus, it is a trustworthy and valid tool for evaluating preoperative anxiety in Arabic speakers. Future research could benefit from using the SAQ in both surgical and psychiatric research.

Psychometric properties of the Swedish version of the Parenting Concerns Questionnaire in parents with cancer.

Parenting concerns can be a major source of distress for patients with cancer who are parents of dependent children; however, these are often not addressed in health care. The Parenting Concerns Questionnaire (PCQ) is an instrument designed to assess parents' worries about the impact of cancer on their children and their ability to parent during this time. The Swedish version of thePCQ has, however, not been evaluated. This study therefore aimed to examine the psychometric properties of the PCQ in a sample of Swedish parents with cancer. A sample of 336 patients with cancer having dependent children (≤18 years) were included in a cross-sectional web-based survey. Participants completed questionnaires assessing parenting concerns, depression, anxiety, and stress symptoms (DASS); self-efficacy, family functioning (FAD-GF); and sociodemographic and clinical characteristics. Descriptive analyses, as well as reliability and validity analyses, were conducted followed by a confirmatory factor analysis of the factor structure proposed by the authors of the original version of the PCQ. The majority were mothers (94.9%) with breast cancer (66.4%) aged 40-50 years (59.5%). The results showed evidence for convergent, criterion, and known group's validity, but the original three-factor structure of the PCQ was not fully supported by confirmatory factor analysis. Evaluating parenting concerns may be an important step towards identifying patients who could benefit from targeted psychosocial interventions. However, the PCQ may require some further refinement to fully capture the breadth of parenting concerns in parents with cancer in different settings.

Companion animal bereavement: Psychometric properties of the Spanish version of the Pet Bereavement Questionnaire

This work provides psychometric data on the validity and reliability of the Spanish adaptation of the Pet Bereavement Questionnaire (PBQ), as well as information on the intensity of bereavement in the Spanish population. The study evaluated 333 Spanish participants of legal age (M = 31.5; SD = 11.6), mostly women (76.3%). Confirmatory factor analysis (CFA) tested the adequacy of three different structures present in literature, finding better fit indexes for a model that kept the original three-factor structure (grief, guilt, and anger) but rearranged 2 of the 16 items. Around 70% of participants reported signs of intense bereavement on the grief scale, with higher means among women. The results confirm adequate psychometric qualities of the PBQ, offering healthcare professionals a tool to evaluate bereavement intensity after the loss of a companion animal in Spanish samples.

Assessment of Postpartum Stress Using the Maternal Postpartum Stress Scale (MPSS) in Spanish Women.

Although scales that evaluate postpartum stress exist, they lack specificity in maternal postpartum stress. The MPSS was created because there was a need to assess maternal stress during the postpartum stage. The introduction of the MPSS has enriched the evaluation tools for postpartum stress and has helped understand maternal stress at various postpartum time points and identify women at high risk for postpartum stress during this period. The aim was to translate the MPSS into Spanish and study its psychometric properties. Postpartum women (N = 167) with a mean age of 34.26 (SD = 4.71) were involved in this study. In addition to the MPSS, a battery of instruments was administered: a demographic sheet, the Birth Satisfaction Scale-Revised (BSS-R) and the Edinburgh Postnatal Depression Scale (EPDS). The MPSS data were analyzed, checking item communality first. As a result, three items showed unsatisfactory communality values (h2 < 0.40). Confirmatory Factor Analysis was conducted, comparing factor models using the full pool of MPSS items or the version without items with unacceptable communality. As a result, the original three-factor structure was endorsed on the Spanish MPSS, with better fit indices when removing items with low communality (RMSEA = 0.067, CFI = 0.99, TLI = 0.99). The reliability of this version was satisfactory (ω = 0.93). Finally, group comparisons for some perinatal variables were performed, showing no significant differences between groups of interest (p = 0.05 and above). To conclude, the MPSS will contribute to the existing literature, having a wider capacity to assess perinatal mental health difficulties in Spanish-speaking populations.

A psychometric evaluation of Professional Quality of Life Scale Version 5 (ProQOL 5) in a UK-based sample of allied mental health professionals

The Professional Quality of Life Scale Version 5 (ProQOL 5; Stamm, 2010) is often used to assess burnout, secondary traumatic stress, and compassion satisfaction in allied mental health professionals in the UK. However, vital empirical evidence assessing psychometric properties of this instrument for this occupational group or in this national context does not exist. Therefore, the aim of the present study was to conduct a confirmatory factor analysis to validate ProQOL 5 in a sample of 366 UK-based clinical psychologists, counsellors, and psychotherapists recruited via online purposive sampling. The findings indicated that in alignment with existing research, the original three-factor structure demonstrated poor fit to data. Thus, the structure was investigated further with a novel technique in network psychometrics called bootstrapped exploratory graph analysis (bootEGA). The results indicated that 21 items from the original 30-item ProQOL 5 demonstrated satisfactory levels of item stability, i.e., all items were replicated in more than 80% of bootstrapped samples. The present study is the first to evaluate the internal structure of ProQOL 5 in a sample of mental health professionals based in the UK.

Internal and external self-affirmation resources: validation and assessment of psychometric properties of the spontaneous self-affirmation measure using structural equation modeling.

People use coping strategies such as self-affirmation to manage threats to their self-esteem. In empirical research, self-affirmation often involves recalling personal values, strengths, or relationships to restore moral integrity. Research shows it improves attitude adjustment, resolves cognitive dissonance, and enhances well-being. Some studies stress the importance of distinguishing between different aspects of self-affirmation, like strengths or social relations. These aspects align with concepts in psychotherapy that differentiate between internal and external resource activation, benefiting health, self-esteem, and resilience. The aim of the current study was twofold: first, to independently test the three-factor structure of the Spontaneous Self-affirmation Measure (SSAM), and second, to integrate self-affirmation strategies into a broader resource activation framework as resilience factors. It also examined associations with self-esteem and effects of age, gender, and education on spontaneous self-affirmation. 1,100 participants (72% female, age 18-65) were recruited online. The original three-factor structure of the SSAM (with the factors Strengths, Values and Social relations) was examined using structural equation modeling. Further, a theory driven two-factor structure applying an internal and external resources framework was examined, integrating the factors of the SSAM into the taxonomy of resource activation (Internal resources: Strengths and Values; External resources: Social relations). The results of confirmatory factor analyses showed that both the original three-factor structure and the complementary two-factor structure with an Internal resources and External resources factor fit the data appropriately. All three factors of the original factor model showed a high reliability (Strengths: = 0.91, Values: = 0.91, Social relations: = 0.92). We also found measurement invariance across age, gender, and education. Furthermore, group differences regarding gender, education and ethnicity in the utilization of spontaneous self-affirmation strategies were apparent. Finally, it was demonstrated that the Internal resources factor of the complementary two-factor model is significantly more strongly correlated with self-esteem than the External Resources factor [z = 12.80, p < 0.001, 95%CIdiff (0.24, 0.33)]. The study confirms the validity of both the three-factor and two-factor structures of the SSAM. Integrating self-affirmation into the resource activation framework may facilitate applying findings from self-affirmation studies to clinical contexts.

Nature Relatedness Scale: psychometric properties of the Portuguese version

Environmental education would strongly benefit from a socioecological approach that encompasses the human-nature relationship in all its dimensions. Nature relatedness appears to be an essential trait to ensure effective approaches, promoting the development of pro-environmental attitudes and behaviors. but also, human well-being through nature-derived benefits. To our knowledge, there are no available instruments validated for the Portuguese population to assess nature connectedness. This study aims to fill this gap, by validating the short and full versions of the Nature Relatedness Scale for the Portuguese population. The translation and adaptation of the questionnaire comply with international guidelines in this field and validation was conducted with 456 Portuguese participants with a mean age of 32.95 (SD = 11.45, age range = 18–77) years, mostly female (n = 328; 71.9%). Confirmatory factor analysis indicated that the original three-factor latent structure of the full Nature Relatedness Scale, and the short version of the instrument with six items, obtained an adequate fit. These two versions of the instrument showed adequate validity to be used with the Portuguese population.

Psychometric properties and measurement invariance of the Czech version of the Temporal Satisfaction with Life Scale

The aim of this study was to validate the Temporal Satisfaction with Life Scale (TSWLS; Pavot et al., 1998) in the Czech language, including the examination of its psychometric properties and measurement invariance by gender and age. The TSWLS is a 15-item instrument for measuring life satisfaction (LS) from a temporal perspective allowing the comparison of the level of life satisfaction in the past, present, and future. The analysis was based on a representative research sample (N = 427) of Czech people older than 18 years. The results confirmed the psychometric quality of the original three-factor structure of the TSWLS as very good in terms of reliability and validity; however, according to the confirmatory factor analysis, the model fit was poor. Some items were identified as problematic and were excluded, resulting in a 12-item version of the TSWLS (without the past1, present1, and future1 items) with correlated residuals between similar items from each subscale. This version provides an acceptable model fit and is recommended for use in future research. The findings from the measurement invariance indicated that the TSWLS allows meaningful comparison across gender and age, since scalar invariance was achieved.

Development and Validation of the Brief Math Anxiety Scale (BMAS) in University Students.

This study developed the Brief Math Anxiety Scale (BMAS), a brief version of the Shortened Math Anxiety Rating Scale (sMARS), maintaining its original three-factor structure, by applying item response theory. The sMARS was administered to 1,349 undergraduates, along with other questionnaires to measure their math ability, trait and test anxieties, and attitudes toward mathematics. Results showed that the original scale could be reduced to nine items (three for each subscale). We provided evidence of good psychometric properties: strong internal consistency, adequate 7-week test-retest reliability, and good convergent/discriminant validity. In conclusion, the BMAS provides valid interpretations and reliable scores for assessing math anxiety in university students, and is especially useful in situations with time constraints where the longer form is impractical.

Psychometric Properties of a Polish Version of the Parenting Concerns Questionnaire Among Parents With Cancer

In this study, I investigated parenting concerns and worries in parents during cancer treatment and examined the psychometric properties of the Polish version of the Parenting Concerns Questionnaire. Reliability, as well as factorial and convergent validity, were analyzed. A total sample size of 145 parents during cancer treatment (parents of children aged 18 years or younger at the time of the survey) participated in the study. The study was an online survey method conducted between January 2019 and December 2021. Parents were sent a survey link and were requested to fill the Perceived Stress Scale (PSS-10), the Parenting Stress Index (PSI-3-SF), the SF-36v2 Health Survey (SF-36v2), and the Family Resilience Assessment Scale (FRAS). The author received permission for using these questionnaires in online research. Confirmatory factor analysis of the Polish version of the Parenting Concerns Questionnaire did not confirm the original three-factor structure. However, the standardized factor loadings for the three factors were moderate to high. Additionally, apart from high-reliability estimates, this instrument proved to have good convergent and discriminant validity for all three factors. The PCQ-PL demonstrated adequate convergent validity with expected correlations with parenting stress, perceived stress, quality of life, and family resilience. The results suggest that the PCQ-PL is a reliable and relatively valid measurement tool to evaluate the level of parental concerns in Polish patients. The PCQ can be a useful tool to recognize parents with cancer who might need psychological support regarding combining the role of a parent and oncological patient.

Psychometric properties of the Depression, Anxiety, and Stress Scale (DASS-21) among different Chinese populations: A cross-sectional and longitudinal analysis

Given that there is limited evidence concerning the psychometric properties of DASS-21 when applied to primary school students, the present study undertook a comprehensive exploration of the psychometric evidence supporting the use of the DASS-21 within this demographic. The research comprised three studies. In Study 1, the basic psychometric properties of internal consistency and construct validity were examined. A total of 3138 primary school students from three provinces in mainland China participated. The internal reliability of the overall scale was 0.93, and for all the subscales, it was higher than 0.80. Construct validity was partially supported. Both exploratory and confirmatory factor analyses upheld the factorial validity of the original three-factor structure. While convergent validity was established, the results showed unsatisfactory discriminant validity. The bifactor model showed that DASS-21 raw scores predominantly indicated the general factor, evidenced by the high explained common variance and omega-hierarchical values. However, the contributions from the three specific factors were minimal, with their omega hierarchical values all below 0.15. In Study 2, a longitudinal design was adopted, tracking 1366 primary school students from Southwest China over a three-month interval. The results further confirmed that the DASS-21 exhibited scalar time-invariance. The latent mean analysis showed that there were no statistically significant differences in the latent means of depression, anxiety, and stress between Time 1 and Time 2. In Study 3, which included 364 college students and 483 enterprise workers, the results demonstrated that the DASS-21 had measurement invariance across different populations. The latent mean analysis further confirmed that, in terms of the latent mean of all three subscales, both college students and enterprise workers had significantly higher scores than primary school students. Overall, the findings indicated that the DASS-21 is a suitable tool for screening schoolchildren for general psychological distress, but it is not suitable for discerning distinct negative mood state disorders.

The representation of child-parent relation: validation of the Italian version of the child-parent relationship scale (CPRS-I).

This study proposes a psychometric validation of the Italian version of the Child-Parent Relationship Scale (CPRS) developed by Pianta in 1992. Based on attachment theory, the scale assesses parents' relationship perceptions with their own child and comprises three scales: Closeness, Conflict, and Dependency. A sample of 501 parents (188 fathers and 313 mothers) completed 30 items of the Italian version of the Child-Parent Relationship Scale (CPRS-I) online, but only 437 answered 85% of the entire protocol; hence, the analyses only focused on 437 participants. The first analysis of the original theoretical model revealed poor fit, item loadings, and internal consistency. Therefore, a follow-up analysis was conducted. Exploratory and confirmatory analyses with a split sample (EFA = 218; CFA = 219) confirmed the original three-factor structure of the Italian sample, although some items were eliminated. The validity and reliability of the Italian version of the CPRS-I were also verified by correlating the above three factors with measures of adult attachment styles and children's internalizing and externalizing behaviors. The CPRS-I showed significant correlations with all tested constructs, in line with those found by Driscoll and Pianta for the short form of the scale. Our results confirm that the CPRS-I has the same structure as the original scale; therefore, it can be a useful tool for assessing parents' perceptions of their relationship with their children. The implications for educational and clinical settings are also discussed.

Validation of the youth-nine item avoidant/restrictive food intake disorder screen.

This study assessed the factorial, divergent, and criterion-related validity of the Youth-Nine Item Avoidant/Restrictive Food Intake Disorder (ARFID) Screen (Y-NIAS) in a paediatric clinical sample at initial evaluation for an eating disorder (ED). Participants included 310 patients (82.9% female, 77.4% White, Age M=14.65) from a tertiary ED clinic. Confirmatory factor analysis (CFA) evaluated the three-factor of the Y-NIAS. One-way analysis of variance compared Y-NIAS scores across diagnoses. A receiver operating curve analysis assessed the ability of each subscale to identify ARFID presentations from the full sample. Two logistic regressions assessed the criterion-related validity of the obtained Y-NIAS cut-scores. CFA supported the original three-factor structure of the Y-NIAS. Clinically-elevated scores were observed in all diagnostic groups except for binge-eating disorder. Subscales were unable to discriminate ARFID cases from other ED diagnoses. Cut scores were identified for picky eating subscale (10) and Fear subscale (9), but not for Appetite subscale. In combination with the ED Examination Questionnaire (EDE-Q), classification accuracy was moderate for ARFID (62.7%) and other EDs (89.4%). The Y-NIAS demonstrated excellent factorial validity and internal consistency. Findings were mixed regarding the utility of the Y-NIAS for identifying clinically-significant ARFID presentations from other ED diagnoses.

Constructivist learning environments: Validating the community of inquiry survey for face-to-face contexts

Serving as a prominent framework for online learning, the Community of Inquiry (CoI), identifies three factors critical to learning in online environments: teaching presence, cognitive presence, and social presence. However, application of the CoI framework to face-to-face classes has not been broadly or systematically explored, despite constructivist paradigms (e.g. flipped classrooms, team-based learning) being increasingly incorporated at the post-secondary level. Further, there remains some debate on whether such constructivist environments adequately support learning, with studies on their effectiveness revealing mixed results, as have studies comparing face-to-face and online learning contexts. A tool that measures students’ perceptions of constructivist learning environments could help address such inconsistencies. The purpose of this study was to validate the CoI scale, a measure developed for online contexts, for use in face-to-face contexts. Undergraduates ( n = 282) enrolled in face-to-face classes incorporating team-based learning completed the 34-item CoI scale. Confirmatory Factor Analysis validated the original three-factor structure for face-to-face classes has acceptable fit, suggesting this tool measures teaching, cognitive, and social presences in face-to-face courses. Further suggestions for how this measure might be used for the purposes of research and instructional feedback are included.

Initial validation of the Multidimensional Adolescent Functioning Scale (MAFS) in Spanish-speaking students from Chilean secondary schools.

Psychosocial functioning is closely associated with psychopathology and wellbeing in different populations, particularly adolescents. Despite its relevance, measures assessing psychosocial functioning in healthy adolescents are scant as most focus on adults or clinical populations. We evaluated the psychometric properties of the Multidimensional Adolescent Functioning Scale (MAFS), a self-report questionnaire created to assess three dimensions of psychosocial functioning ('general functioning', 'family-related functioning', and 'peer-related functioning') in adolescents from the general population. After translation and cultural adaptation, we administered the Spanish MAFS to 619 adolescents aged 14 to 19. We assessed the factor structure, internal consistency, and associations with depressive symptoms, suicidal ideation, cognitive-behavioral skills, cognitive reappraisal (CR), and expressive suppression (ES). We additionally tested for measurement invariance based on biological sex. The original three-factor structure showed the best fit. Internal consistency was good for the total scale (ω = 0.874; α = 0.869; GLB = 0.939, rM=0.216) and for all subscales (ω = 0.806-0.839; α = 0.769 to 0.812; GLB = 0.861-0.873). Correlations between all three MAFS subscales were significant, ranging between 0.291 and 0.554. All MAFS subscales correlated positively and significantly with cognitive-behavioral skills and adaptive regulatory strategies and negatively with depressive symptoms and suicidal ideation. The Spanish MAFS translation is a valid and reliable self-report measure to assess three domains of psychosocial functioning in adolescents aged 14-19 from the general population.

Translation and psychometric validation of the Persian version of palliative care attitudes scale in cancer patients

IntroductionTo improve cancer patients’ quality of life, palliative care is necessary. The growth of palliative care, along with the assistance of the government and the collaboration of specialists, also relies on the knowledge and attitude of people. In Iran, there is no tool available to gauge patient attitudes about palliative treatment. The Persian version of the Palliative Care Attitude Scale (PCAS-9) was translated and psychometrically validated in this research among cancer patients.MethodsThis methodological study was conducted in two stages: translation stage and psychometric validation stage. The method of translation was based on that proposed by Polit and Yang. Utilizing a qualitative approach, the scale’s face and content validity were investigated. 162 cancer patients who required palliative care based on expert diagnosis participated in the confirmatory factor analysis to establish construct validity. Stability and internal consistency provided evidence of reliability. The data was examined using SPSS18 and AMOS.ResultsThe “Palliative Care Attitudes Scale” translated well across cultures. Validity on both the face and the content was acceptable. Confirmatory factor analysis (CFA) revealed a good fit for the original three-factor structure. The intra-class correlation coefficient (ICC) was equal to 0.89, while the internal consistency (Cronbach’s alpha) reliability of the whole scale was equal to 0.77.ConclusionsPersian version of the “Palliative Care Attitudes Scale” was acceptable and adequate in cancer patients. Using this tool makes it easier to assess how patients feel about receiving palliative care and how well training sessions are working to change patients’ views.

French Validation of the Camouflaging Autistic Traits Questionnaire (CAT-Q).

Autistic camouflaging is a collection of strategies used to hide autistic characteristics. It can have serious consequences on autistic people's mental health and needs to be addressed and measured in clinical practice. The purpose of this study is to evaluate the psychometric properties of the French adaptation of the Camouflaging Autistic Traits Questionnaire. 1227 participants (744 autistic, 483 non-autistic) answered the French version of the CAT-Q in an online survey or on paper. Confirmatory factor analysis, measurement invariance testing, internal consistency analysis (McDonald's ω), and convergent validity with the DASS-21 depression subscale were conducted. Test-rest reliability was assessed on a sample of 22 autistic volunteers using intraclass correlation coefficient. A good fit was found for the original three-factor structure as well as a good internal consistency, excellent test-retest reliability and highly significant convergent validity. Measurement invariance testing indicates however that the meaning behind items is different for autistic vs. non-autistic people. The French version of the CAT-Q can be used in clinical settings to assess camouflaging behaviors and intent to camouflage. Further research is needed to clarify the camouflage construct and whether reported measurement noninvariance are due to cultural differences or a true difference in what camouflaging might mean for non-autistic people.

Mentalization Scale (MentS): Validity and reliability of the Iranian version in a sample of nonclinical adults.

Mentalizing incapacity is increasingly identified as a common factor in psychopathology. The Mentalization Scale (MentS) is a cost-effective measure built upon the dimensional model of mentalizing. We aimed to evaluate the psychometric properties of the Iranian version of MentS. Two samples of community-based adults (N1 =450, N2 =445) completed different batteries of self-report measures. In addition to MentS, participants completed measures of reflective functioning and attachment insecurities in the first sample and a measure of emotion dysregulation in the second sample. Due to the conflicting results of confirmatory and exploratory factor analyses, an item-parceling approach was applied, which replicated the original three-factor structure of MentS, yielding Self-Related Mentalization, Other-Related Mentalization, and Motivation to Mentalize. The reliability and convergent validity of MentS were supported in both samples. Our findings provided preliminary evidence for using the Iranian version of MentS in nonclinical populations as a reliable and valid measure.

Exploring the associations between the Morningness-Eveningness-Stability-Scale improved (MESSi) and the higher-order personality factors

ABSTRACT Morningness-eveningness refers to individual differences in the sleep-wake cycle. Research indicates that morningness-eveningness is associated with the Big Five (neuroticism, extraversion, openness to experience, agreeableness, conscientiousness) and the Big Two (alpha-stability, beta-plasticity) personality factors. However, the latter has not yet been tested within the multidimensional approach to morningness-eveningness. In the present study, we have adapted the Morningness-Eveningness-Stability-Scale improved (MESSi) to Polish (https://osf.io/rcxb5) to explore the associations between its subscales (morning affect, eveningness, distinctness) and the Big Two personality traits in a sample of 1106 participants (559 women and 547 men) aged 18 to 55 (M = 36.26, SD = 9.90). In bivariate correlations, morning affect was positively related to alpha-stability and beta-plasticity, distinctness was correlated negatively with alpha-stability and beta-plasticity, while eveningness was positively correlated only with beta-plasticity. Furthermore, the confirmatory factor analysis supported the original three-factor structure of the Polish version of MESSi, while the associations with affect and the symptoms of depression and anxiety attested to its validity. Overall, the present study provides the first evidence for the associations between MESSi subscales and the Big Two personality traits, as well as shows a good fit of the three-factor structure of MESSi in the Polish population.

Psychometric validation of the French version of the adverse childhood experiences international questionnaire (ACE-IQ)

ObjectiveSince Dr. Vincent Felitti conducted his seminal work on adverse childhood experiences (ACEs) in the 1980′s, a large body of literature has emerged concerning the relation between early life adversity and physical and psychological health outcomes in adulthood. The objective of this study was to assess the psychometric properties of the French version of the Adverse Childhood Experiences International Questionnaire (ACE-IQ). A validated translation of the ACE-IQ will facilitate comparing data in French-speaking countries where this tool is used to measure a dose–response relationship between adverse childhood experiences (ACEs) and health decline in adulthood. MethodThe ACE-IQ is a 29-item measure designed to assess exposure to ACEs categorized into three groups: maltreatment (all forms of physical and emotional ill-treatment, sexual abuse, neglect), family dysfunction and violence outside the home. The questionnaire was translated and back-translated according to guidelines and methodology defined by the World Health Organization, 2011 (WHO). A total of 367 participants were recruited to take part in this study. After analyzing descriptive statistics, we assessed the questionnaire’s internal structure using principal component factor analysis. Based on classical test theory we calculated internal consistency and test–retest reliability. We then performed an item response theory (IRT) analysis using a partial credit model (PCM) for polytomous data, which was applied to each of the three dimensions of the ACE-IQ. ResultsTaken together, our results suggest that while the original three-factor structure was not fully supported, the psychometric properties were good. A high degree of overall internal consistency was demonstrated with an alpha coefficient of 0.80. For the three dimensions of the questionnaire Cronbach’s alphas ranged between 0.77 and 0.41. In terms of temporal stability, we observed a good intra-class correlation of 0.79 for the entire questionnaire, with temporal stability for the three dimensions ranging between 0.78 and 0.61. Finally, our IRT analysis revealed discrepancies on certain items for each of the three dimensions, which confirm, and complete findings previously obtained through classical analysis. ConclusionThe French translation of the ACE-IQ has good psychometric properties which make it a reliable and valid measure for assessing ACEs in French-speaking populations, both for research purposes and clinical practice.Further validation will be necessary, however, to account for different cultural characteristics and perspectives between French speaking countries.
