Psychometric evaluation of the Chinese version of the hospital-acquired insomnia scale (HAIS) and analysis of influencing factors.

BACKGROUND: Adequate sleep and rest are essential for patient recovery; however, lack of sleep has become a common problem faced by Chinese patients during hospital stays. Reduced sleep is often associated with a higher risk of disease progression and is strongly associated with increased hospital stay. However, there is no specific tool in China to assess short-term insomnia caused by hospitalization. This study aimed to translate the Hospital-acquired Insomnia Scale (HAIS) into Chinese, test its applicability to Chinese inpatients through reliability and validity indicators, and investigate the potential influencing factors of hospital-acquired insomnia. METHODS: Psychometric analysis from a sample of 679 hospitalized patients to whom the HAIS questionnaire was applied. The structural validity was assessed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and the content validity of the scale was assessed using the content validity index. Cronbach's alpha coefficient, split-half reliability and test-retest reliability were calculated to evaluate the internal consistency of the scale. Multiple stepwise linear regression analysis was conducted to determine the potential correlates of hospital-acquired insomnia. RESULTS: EFA supported a four-factor structure with factor loadings for all dimensions greater than 0.40. CFA showed good indicators of model fit. The content validity index of the scale was 0.94. the Cronbach's alpha of the scale was 0.915, the split-half reliability coefficient was 0.819, and the retest reliability was 0.844. Gender, age, total hours of sleep during the night, medical insurance, length of hospital stay, perceived stress level, and perceptions about sleep explained 46.2% of the variance in hospital-acquired insomnia. CONCLUSION: The Chinese version of HAIS has good psychometric characteristics and is an effective instrument for evaluating hospital-acquired insomnia. In addition, hospital-acquired insomnia is more common in women, of younger age, less than 5 h of sleep a night, without medical insurance, stressed, and patients with more misconceptions about sleep.

Validation and psychometric evaluation of the French version of the recovery experience questionnaire: internal consistency and validity assessment.

Background: Entrepreneurs often experience high levels of stress, anxiety, and burnout due to the demanding nature of their professional activities. Therefore, recovery from work-related stress is a relevant activity for entrepreneurs. The Recovery Experience Questionnaire (REQ) is a widely used 16-item self-reported measure covering four recovery factors: psychological detachment from work, relaxation, mastery, and control. The present study addresses the validation of a French version of the REQ. Methods: A total of 1,043 French entrepreneurs from various sectors participated in this study. Internal consistency and correlations were examined to assess the psychometric properties of the French version of the REQ. Confirmatory factor analysis (CFA) was used to validate the four-factor structure of the REQ, with seven error covariances added to improve model fit. Results: The French version of the REQ demonstrated good internal consistency (psychological detachment: α = 0.88, relaxation: α = 0.91, mastery: α = 0.90, control: α = 0.91). CFA supported that the four-factor structure was confirmed based on the following data: RMSEA = 0.071 (95% CI [0.066, 0.077]), CFI/TLI = 0.955/0.950, SRMR = 0.050, and χ2 (108) = 593.861, p < 0.001. Significant correlations were found between REQ scores and health indicators such as stress, loneliness, physical health, mental health, and sleep quality. The results confirm that the REQ is a valid and reliable measure for assessing recovery experiences among French entrepreneurs. Conclusion: We conclude that the REQ is a valid measure and a useful tool for research on entrepreneurs' general health. Additionally, the validated French version of the REQ can be applied to other working populations, making it a versatile instrument for evaluating health and recovery in diverse occupational settings. To support this claim, we conducted the same validation analysis on a sample of 1,231 French agricultural employees, again showing that REQ is a valid and reliable measure for assessing recovery experiences.

Testing, revision and application of the social anxiety scale for Chinese social media users.

This study aims to modify the Social Anxiety Scale for Social Media Users (SAS-SMU) to make it more suitable for assessing social anxiety among Chinese social media users, taking into account the unique cultural nuances and social media usage patterns in China. Consequently, a systematic approach was adopted, involving three distinct studies. Study 1 involved translating the English scale into Chinese, conducting interviews with Chinese social media users, and subsequently revising the scale items based on the interview data to ensure cultural appropriateness. Study 2 employed an online survey to collect data and examine the reliability and construct validity of the revised scale, including a two-phase approach: an exploratory factor analysis (EFA) was conducted with 500 participants to identify the underlying factor structure, and a subsequent confirmatory factor analysis (CFA) with 408 participants was used to cross-validate the results. Thus far, this study has developed a social anxiety scale for Chinese mobile social media users (SAS-CMSMU) consisted of 11 items on three factors: Interaction Anxiety, Privacy Concern Anxiety, and Shared Content Anxiety. Study 3 (N = 1,006) applied the SAS-CMSMU to assess social anxiety among Wechat users. The results indicated that participants showed a high level of overall social anxiety (M = 3.646 > 3). Specifically, Privacy Anxiety was the most pronounced, followed by Shared Content Anxiety and Interaction Anxiety. Moreover, significant statistical differences in social anxiety levels were found among WeChat users across gender, age, education, income, and relationship status.

Development and validation of the Upstream Social Interaction Risk Scale (U-SIRS-13): a scale to assess threats to social connectedness among older adults.

Background: Social interactions are essential to social connectedness among older adults. While many scales have been developed to measure various aspects of social connectedness, most are narrow in scope, which may not be optimally encompassing, practical, or relevant for use with older adults across clinical and community settings. Efforts are needed to create more sensitive scales that can identify "upstream risk," which may facilitate timey referral and/or intervention. Objective: The purposes of this study were to: (1) develop and validate a brief scale to measure threats to social connectedness among older adults in the context of their social interactions; and (2) offer practical scoring and implementation recommendations for utilization in research and practice contexts. Methods: A sequential process was used to develop the initial instrument used in this study, which was then methodologically reduced to create a brief 13-item scale. Relevant, existing scales and measures were identified and compiled, which were then critically assessed by a combination of research and practice experts to optimize the pool of relevant items that assess threats to social connectedness while reducing potential redundancies. Then, a national sample of 4,082 older adults ages 60 years and older completed a web-based questionnaire containing the initial 36 items about social connection. Several data analysis methods were applied to assess the underlying dimensionality of the data and construct measures of different factors related to risk, including item response theory (IRT) modeling, clustering techniques, and structural equation modeling (SEM). Results: IRT modeling reduced the initial 36 items to create the 13-item Upstream Social Interaction Risk Scale (U-SIRS-13) with strong model fit. The dimensionality assessment using different clustering algorithms supported a 2-factor solution to classify risk. The SEM predicting highest risk items fit exceptionally well (RMSEA = 0.048; CFI = 0.954). For the 13-item scale, theta scores generated from IRT were strongly correlated with the summed count of items binarily identifying risk (r = 0.896, p < 0.001), thus supporting the use of practical scoring techniques for research and practice (Cronbach's alpha = 0.80). Conclusion: The U-SIRS-13 is a multidimensional scale with strong face, content, and construct validity. Findings support its practical utility to identify threats to social connectedness among older adults posed by limited physical opportunities for social interactions and lacking emotional fulfillment from social interactions.

Validation of the Japanese version of the Patient Health Questionnaire-4 (PHQ-4-J) to screen for depression and anxiety.

OBJECTIVE: We aimed to validate the Japanese version of the Patient Health Questionnaire-4 (PHQ-4-J). People in Japan, especially healthcare workers (HCWs) suffer from high rates of mental health symptoms. The PHQ-4 is an established ultra-brief mental health measure used in various settings, populations and languages. The Japanese version of the PHQ-4 has not been validated. METHODS: Two hundred eighty people in Japan (142 HCWs and 138 from the general public) responded to the PHQ-4-J. Internal consistency, and factorial validity were assessed using confirmatory factor analysis (CFA) and Multiple Indicators Multiple Causes (MIMIC) models. RESULTS: Internal consistency was high (α = 0.70-0.86). CFA yielded very good fit indices for a two-factor solution (RMSEA = 0.04, 95% CI 0.00-0.17) and MIMIC models indicated the performance differed between HCWs and the general population. CONCLUSIONS: The PHQ-4-J is a reliable ultra-brief scale for depression and anxiety in Japanese, which can be used to meet current needs in mental health research and practice in Japan. Disaster research and gerontology research can benefit from this scale, enabling mental health assessment with little participant burden. In practice, early detection and personalised care can be facilitated by using the scale. Future research should target specific populations in Japan during a non-emergency time.

Psychometric Evaluation of the Personal Mastery Scale Among Italian Nurses: Assessing Personal Mastery in the Nursing Profession.

Background and Purpose: Personal mastery is essential in the nursing profession, as it directly impacts the quality of care and the well-being of the nurses themselves. However, there is a lack of psychometrically reliable tools to measure it among nurses. This study evaluates the applicability of the Personal Mastery Scale (PMS) among Italian nurses. Methods: A cross-sectional study surveyed Italian nurses using self-administered questionnaires, including the PMS. A total of 209 healthcare workers, primarily nurses, from various operational units participated in the study. The majority of respondents (84.2%) were nurses. The gender distribution was predominantly female (83.3%). Results: Statistical analyses, including factor analyses, assessed the scale's reliability and validity. The scale demonstrated adequate internal consistency (Cronbach's alpha = .670) and construct validity. Conclusions: The Italian version of the PMS is a reliable and valid tool for assessing personal mastery among nurses. Understanding personal mastery is crucial for promoting resilience and delivering quality care. Further research should explore its relationship with outcomes and intervention effectiveness.

Examination of the psychometric properties of the short and long forms of the Family Health Scale in Turkish culture.

PURPOSE: A healthy family is very important for community health. This study was conducted to test the validity and reliability of the short and long forms of the Family Health Scale (FHS) in Turkish culture. DESIGN AND METHODS: This is a cross-cultural adaptation and validation of instruments using a methodological approach. A total of 783 individuals aged between 18 and 65 from Turkey. The test-retest reliability analysis of FHS was performed with 64 participants after four weeks. RESULTS: Confirmed that the long form of the FHS was four-dimensional and the short form was one-dimensional. The results of the confirmatory factor analysis showed that the long and short forms fit well with the data, and it was determined that all fit indices were within acceptable limits. The Cronbach alpha of the long form of the FHS was 0.911, the cronbach alphas of the four sub-dimensions ranged from 0.833 to 0.908, and short form was 0.872. The pearson correlation coefficient between the forms was 0.919 (p = 0.000). CONCLUSIONS: The results of the study revealed that the FHS is a valid and reliable measurement tool that can be used specifically for Turkish society. PRACTICE IMPLICATIONS: Nurses can use both forms of the FHS to examine family health and trends in family health in the population they serve. The FHS may be an important screening tool in health care settings and family intervention programs. Nurses can use FHS when providing health care so that children grow up in a healthy family.

Psychometric Properties of Korean Version of Nonsuicidal Self-injury Inventory: Validation Study of Deliberate Self-harm Inventory.

Objective: This study aimed to develop a Korean version of the Nonsuicidal Self-injury Inventory (K-NSSI) through the Deliberate Self-harm Inventory (DSHI) developed by Gratz for the Korean context and confirm its reliability and validity for clinical application. Methods: A total of 188 participants were analyzed utilizing the DSHI, the Korean version of the Self-harm Inventory, the Personality Assessment Inventory-Borderline Features (PAI-BOR), and the DSM-5 Level-2-Depression scale (Level-2-Dep). Cronbach's α assessed their reliability, while frequency analysis examined the items of the K-NSSI scales. Validity of the K-NSSI was confirmed through correlation analyses between K-NSSI (tendency for and frequency of nonsuicidal self-injury [NSSI] behavior) and SHI, PAI-BOR total scale, four subscales of PAI-BOR, and Level-2-Dep scale. Polyserial correlations analyzed the correlation between the presence of NSSI behavior and other scales. Confirmatory factor analysis and structural equation modeling explored the relationship between borderline personality features and self-harm. Results: Cronbach's α was 0.71, indicating an "acceptable" level of reliability. Statistically significant correlations were observed between the presence of NSSI behavior and the total scores of SHI and PAI-BOR, and the four subscales of PAI-BOR. The frequency of NSSI showed statistically significant correlations with the total score of SHI and PAI-BOR, and its four subscales. Notably, 13.8% of participants reported engaging in self-harm behaviors, 26.9% reported a single occurrence, and 73.1% reported two or more instances. Structural equation modeling demonstrated that self-harm adequately predicted borderline personality traits. Conclusion: This study successfully validated the adaptation of DSHI into K-NSSI. The K-NSSI can facilitate interventions for self-harm incidents.

Assessing basic/fundamental psychological need fulfillment: systematic mapping and review of existing scales to foster cumulative science.

Background: Because the fulfillment of basic/fundamental psychological needs affects people's motivation and well-being, measuring the degree to which these needs are met is of interest to researchers across various domains. Although numerous self-assessment tools have been developed, no recent comprehensive reviews exist, hindering cumulative scientific progress. The present systematic review aimed to identify and analyze the main approaches to developing self-report scales for assessing basic/fundamental psychological need fulfillment. The objective is to inform readers interested in selecting instruments for their studies and those intending to develop new scales. Methods: Following PRISMA, we conducted a search of Scopus, Web of Science, PubMed, and ProQuest in August 2023. The following information was extracted from eligible studies: Scale name, abbreviation, theoretical basis, application domain, final scale construction, scale development and validation methodology, and citation count. Results: Our search identified 32 primary studies, in which 31 original scales were developed and validated, and 89 secondary studies that aimed to modify these original scales. The predominant theoretical basis was Self-Determination Theory, although eight scales were based on alternative need typologies. The scales were either domain-general or specific to contexts such as work, education, or exercise/sports contexts. While most were designed to measure need satisfaction, some also addressed need support, frustration, and thwarting. Conclusion: Despite significant efforts in developing, adapting, and applying scales to measure need fulfillment, we found several issues resulting from diverse perspectives on conceptualizing psychological needs and need typologies, discordant approaches in developing and validating measures, and other inconsistencies that should be acknowledged and addressed in future research.

Validation of the French version of the Body Awareness Questionnaire: toward a way to assess alexisomia.

Background: Awareness of one's own states is a particularly important part of cognition and emotion regulation. Recently, the concept of alexisomia has been used to refer to lack of awareness and expression of somatic sensations. Developing self-reported questionnaires to evaluate alexisomia represents a challenge for clinical psychology and medicine. In this context, we suggested to adapt the Body Awareness Questionnaire in French to measure alexisomia and its relation to alexithymia. In fact, we carried out a backtranslation and studied the validity of the construct in relation to proximal constructs around emotional awareness. Methods: For this study, 610 university students completed questionnaires measuring a three dimensions alexithymia concept [with The Toronto Alexithymia Scale (TAS-20)] or the five dimensions alexithymia concept [with The Bermond-Vorts Alexithymia Questionnaire (BVAQ-B)] and alexisomia (with the BAQ). Results: Confirmatory factor analyses showed that the BAQ can be envisaged through 4 factors as well as a unidimensional model to refer to alexisomia. We also found that body awareness was negatively related to scores of alexithymia. Conclusion: Results are discussed in light of the construct of alexisomia and its clinical implications in somatic as well as mental disorders. We suggest that the BAQ, which assesses interoception, can contribute, in part, to the assessment of alexisomia. Like alexithymia, this is a key concept to take into consideration when designing treatment and prevention programs.

Development and validation of the mpox stigma scale (MSS) and mpox knowledge scale (MKS).

BACKGROUND: Few validated brief scales are available to measure constructs that may hinder mpox-related prevention and care engagement, such as knowledge and stigma. Both are highly salient barriers to infectious disease care and disease understanding, precursors to evaluating one's risk and need to, for example, accept vaccination. To address this gap, we developed and validated the Mpox Stigma Scale (MSS) and Mpox Knowledge Scale (MKS). METHODS: As part of a full-scale clinical trial, we offered an optional mpox survey to participants who self-identified as African American or Black, were 18-29 years old, and lived in Alabama, Georgia, or North Carolina (2023, N = 330). We calculated psychometric properties through confirmatory factor analyses (CFA) and applied Comparative Fit Index (CFI), Goodness of Fit Index (GFI), and Tucker-Lewis Index (TLI) values equal to or exceeding 0.90 and Root Mean Square Error of Approximation (RMSEA) and Standardized Root Mean Square Residual (SRMR) values less than 0.08 to determine adequate model fit. We computed internal reliability using Cronbach's alpha and calculated Pearson or Spearman correlation coefficients between the MSS and MKS and related variables. RESULTS: For the MSS, CFA results showed that the one-factor model fit the data well (χ2(df = 5, N = 330) = 34.962, CFI = 0.97, GFI = 0.99, TLI = 0.94, RMSEA = 0.13, SRMR = 0.03). For the MKS, the one-factor model provided a good fit to the data (χ2(df = 6, N = 330) = 8.44, CFI = 0.99, GFI = 0.99, TLI = 0.95, RMSEA = 0.15, SRMR = 0.02). Cronbach's alphas were MSS = 0.91 and MKS = 0.83, suggesting good to excellent reliability. The MSS was correlated with the MKS (r = .55, p < .001), stigmatizing attitudes (r = .24, p < .001), attitudes towards mpox vaccination (r=-.12, p = .030), and worry about contracting mpox (r = .44, p < .001). The MKS was correlated with worry about contracting mpox (r = .30, p < .001) and mpox disclosure (r=-.16, p = .003). CONCLUSIONS: The MSS and MKS are reliable and valid tools for public health practice, treatment and prevention research, and behavioral science. Further validation is warranted across populations and geographic locations. TRIAL REGISTRATION: ClinicalTrials.gov NCT05490329.

Development and validation of a survey instrument for reusable sanitary products toward sustainable menstrual hygiene.

The predominant use of disposable, non-organic menstrual products has significant environmental impacts due to waste and resource depletion. Concerns over the environmental, economic, and health implications of menstrual hygiene management (MHM) have highlighted the need to explore sustainable options like reusable sanitary pads (RSPs). Despite their benefits, the adoption of RSPs is limited by a lack of awareness, availability, cost, and research. This study emphasizes the need for the development of an instrument that can capture the effectiveness, safety, and user satisfaction of RSPs, addressing a significant gap in the literature. Using a convenient sampling method, data were collected through a structured offline survey and the sample comprised 446 South Asian women of reproductive age. The instrument included 15 items designed to measure factors such as comfort, hygiene, convenience, and environmental consciousness. The instrument's reliability and validity are thoroughly assessed using reliability and factor analysis to ensure its effectiveness in capturing the multifaceted dimensions of MHM product choices. The study revealed that the overwhelming majority of women would prefer the option of RSPs that are comfortable, accessible, and easy to use and dispose of. The findings aim to provide a validated tool for manufacturers, policymakers, and researchers to evaluate reusable pads, promoting their broader acceptance and adoption of a sustainable and equitable approach to menstrual hygiene.

Psychometric properties of Arabic-translated-related quality of life scales for people with parkinson disease: a scoping review.

BACKGROUND: Parkinson's disease (PD) substantially contributes to poor functional outcomes, loss in productivity, and poor health-related quality of life (HRQoL). Despite the existence of various scales, there is a notable gap in existing HRQoL reviews with regard to the availability of Arabic validated scales. As a response to this gap, the aim of our scoping review is to identify validated scales, focusing on their psychometric validation procedures, to contribute valuable insights to the understanding of HRQoL among the Arabic-speaking people with PD. METHODS: A scoping review was conducted at the end of December 2022, using the Medline and Embase databases. The focus of this review was on examining the psychometric properties and validation procedures of included scales. Articles were included in the full-text screening process if they focused on people with PD of any age, included a scale measuring HRQoL in Arabic, and were written in English, French, or Arabic. RESULTS: After applying inclusion/exclusion criteria, 10 studies were selected to analyze HRQoL scales validated in people with PD. However, the PDQ-39 is the only HRQol PD specific scales validated in the Arabic language. Five studies validated in people with PD were identified in the context of instrument validation (3 generic, 1 specific validated in 2 studies). CONCLUSION: There are several HRQoL measurement scales for people with PD. However, only one specific HRQoL instrument has been validated in Arabic for people with PD. For the remaining instruments identified they were just used in people with PD without being validated in this population.

Italian Version of the Hospital Aggressive Behaviour Scale-Users: Initial Psychometric Evaluation among Hospital Healthcare Professionals.

BACKGROUND: Healthcare professionals frequently encounter various forms of aggression, ranging from verbal abuse to physical assaults, which can compromise both their occupational well-being and patient-care quality. Despite its prevalence and serious consequences, workplace aggression is often underreported due to a lack of standardized assessment tools. This study aims to develop a valid Italian version of the Hospital Aggressive Behaviour Scale-Users. METHODS: The scale's structure was evaluated using exploratory (EFA) and confirmatory (CFA) factor analyses on two samples of healthcare professionals during and after the pandemic. Reliability, measurement invariance, and nomological validity were examined. RESULTS: EFA revealed a two-factor structure comprising eight items (χ2 = 59.651, df = 13, p = 0.00; CFI = 0.98; TLI = 0.95; RMSEA = 0.07; SRMR = 0.02), distinguishing non-physical and physical aggression, and meeting all recommended criteria. CFA confirmed this structure, demonstrating good reliability and outperforming alternative models. The same factor structure was confirmed in standard (χ2 = 35.01, df = 19, p = 0.00; CFI = 0.99; TLI = 0.99; RMSEA = 0.03; SRMR = 0.02) and emergency (χ2 = 30.65, df = 19, p = 0.04; CFI = 0.98; TLI = 0.97; RMSEA = 0.06; SRMR = 0.04) contexts. Full residual invariance was found across job tenure groups. Aggression was positively associated with emotional exhaustion, psychological distance, psychosomatic symptoms, post-traumatic stress symptoms, and turnover intentions while negatively related to job satisfaction. Nurses and healthcare assistants reported higher levels of aggression than doctors. CONCLUSIONS: This study provides a reliable, context-specific instrument for documenting and analysing outsider aggression. The insights can inform targeted interventions, contributing to a healthier hospital environment.

Development and validation of the mobile adherence satisfaction scale (MASS) for medication adherence apps.

OBJECTIVE: To develop and validate the Mobile Adherence Satisfaction Scale (MASS) for assessing user satisfaction with mobile health applications aimed to improve medication adherence. METHODS: The study involved patients over 18 with asthma, hypertension, heart failure, or diabetes, who used the CareAide® app for six months. Scale development included a literature review, expert consultations, and patient interviews, initially identifying 129 items. These were refined to 27 using a two-round Delphi technique and grouped into six dimensions: user interface, perceived usability, system quality, service quality, feature satisfaction, and general satisfaction. A pilot study with 30 participants further refined the model, which was then validated with 135 participants using exploratory and confirmatory factor analyses in SPSS 29 and SmartPLS 4. Data were collected via self-administered questionnaires. RESULTS: A total of 135 complete questionnaires were analysed. Respondents had an average age of 66.7 years (SD = 11.6) with 42.2 % male (n = 57) and 57.8 % female (n = 78). After removal of an item due to cross loading, exploratory factor analysis resulted six dimensions and 26 items with Kaiser-Meyer-Olkin measure of 0.837 and Bartlett's Test of Sphericity (χ2(n = 325) = 2085.673, P < 0.001). The confirmatory factor analysis confirmed high reliability and validity: Cronbach's alpha values > 0.70 for each dimension and an overall alpha of 0.89, with Composite Reliability and Average Variance Extracted both >0.70 and >0.50, respectively, for each dimension. Structural model indicated a significant positive impact of user interface (ß = 0.226, P = 0.006) and feature satisfaction (ß = 0.230, P = 0.002) on general satisfaction, explaining 23.1 % of the variance (R2 = 0.231). CONCLUSION: The study developed and validated the MASS, a reliable tool for assessing user satisfaction with mHealth apps. User interface design and feature satisfaction are key for long-term engagement and consistent medication adherence.

Music@Home-Retrospective: A new measure to retrospectively assess childhood home musical environments.

Early home musical environments can significantly impact sensory, cognitive, and socioemotional development. While longitudinal studies may be resource-intensive, retrospective reports are a relatively quick and inexpensive way to examine associations between early home musical environments and adult outcomes. We present the Music@Home-Retrospective scale, derived partly from the Music@Home-Preschool scale (Politimou et al., 2018), to retrospectively assess the childhood home musical environment. In two studies (total n = 578), we conducted an exploratory factor analysis (Study 1) and confirmatory factor analysis (Study 2) on items, including many adapted from the Music@Home-Preschool scale. This revealed a 20-item solution with five subscales. Items retained for three subscales (Caregiver Beliefs, Caregiver Initiation of Singing, Child Engagement with Music) load identically to three in the Music@Home--Preschool Scale. We also identified two additional dimensions of the childhood home musical environment. The Attitude Toward Childhood Home Musical Environment subscale captures participants' current adult attitudes toward their childhood home musical environment, and the Social Listening Contexts subscale indexes the degree to which participants listened to music at home with others (i.e., friends, siblings, and caregivers). Music@Home-Retrospective scores were related to adult self-reports of musicality, performance on a melodic perception task, and self-reports of well-being, demonstrating utility in measuring the early home music environment as captured through this scale. The Music@Home-Retrospective scale is freely available to enable future investigations exploring how the early home musical environment relates to adult cognition, affect, and behavior.

The Alliance Negotiation Scale - Therapist Version: Psychometric Properties in a Sample of Portuguese Psychologists.

Background: The transtheoretical conceptualization of the working alliance and the resultant evaluation tools often overestimate the collaboration between therapist and client, while neglecting the negotiation process. The degree to which therapists and clients can negotiate disagreements regarding goals and tasks is an important indicator in establishing and maintaining the alliance. Even though the negotiation concept is not new, there is still a lack of reliable and parsimonious self-report measures of the construct. The purpose of this study was to translate, execute the cultural adaptation and, also, to perform a preliminary psychometric analysis of the Portuguese form of the therapist version of the Alliance Negotiation Scale (ANS-T_Pt). Method: Data were collected online from 100 Portuguese psychologists. Two random sub-samples were used to conduct both exploratory factorial analysis and confirmatory factorial analysis. Convergent validity was assessed through comparison with the Portuguese version of the Working Alliance Inventory. Results: The ANS-T_Pt showed a one-factorial structure, consistent with previous versions, and demonstrated adequate internal consistency. Evidence supporting criterion-related validity was found based on the correlations between ANS-T_Pt and WAI-T scores. The results showed moderate to large associations between the instruments. These results support the usefulness of the scale, construct's relevance and its transtheoretical nature. Conclusion: These results are a step forward for Portuguese therapists' and researchers' ability to evaluate the bond between client and therapist and to compare results from different countries.

Translation and Validation of a Vietnamese Version of the Colorectal Cancer Subscale for the Functional Assessment of Cancer Therapy - Colorectal Questionnaire.

Introduction: There is a need for a validated Vietnamese translation of the colorectal cancer subscale (CCS) of the functional assessment of cancer therapy-colorectal (FACT-C) questionnaire to assess colorectal cancer-specific concerns of Vietnamese persons with colorectal cancer post-surgery. Objectives: This study aims to translate and validate the CCS of FACT-C questionnaire in Vietnamese persons with colorectal cancer post-surgery. Methods: The nine-item CCS was translated following the functional assessment of chronic illness therapy (FACIT) translation methodology guidelines. Psychometric properties of a Vietnamese version of the CCS were evaluated with a sample of 135 participants who were randomly selected from three hospitals in Vietnam, utilizing a multistage sampling method. Construct validity was examined through confirmatory factor analysis (CFA), and reliability was assessed using Cronbach's α coefficients. These measures aimed to validate the psychometric properties of the Vietnamese nine-item CCS version. Descriptive statistics were used to analyze participant demographics with SPSS. Results: The translated version demonstrated equivalence to the original English version. CFA results for the CCS Vietnamese version indicated that all 9 items were consistent with a unidimensional questionnaire (χ2 = 69.669, p > .05, df = 27, χ2/df = 2.58, RMSEA = .074, CFI = .917, TLI = .901, SRMR = .057). The Cronbach's α coefficient was .86, indicating high reliability. The Correlated Item-Total Correlation for the 9 items ranged from .39 to .76. Conclusion: The nine-item CCS Vietnamese version demonstrated appropriate translation, establishing its validity and reliability in measuring colorectal cancer-related concerns within the health-related quality of life among Vietnamese persons post-surgery.

Adaptation and validation for use in Brazil of the Confusion, Hubbub, and Order Scale (CHAOS).

BACKGROUND: The Confusion, Hubbub, and Order Scale (CHAOS in English Version) was originally developed in the USA by Matheny et al (Bringing order out of chaos: psychometric characteristics of the confusion, hubbub, and order scale. Journal of Applied Developmental Psychology 16(3):429-444, 1995) to measure chaos in the family environment, characterized by confusion, lack of routine, and organization. OBJECTIVE: To present evidence of content validity, internal structure validity, and validity based on relationships with external measures of an adapted version of the CHAOS into Brasilian Portuguese with adolescents sample in São Paulo - Brasil. METHOD: Study 1 involved the translation/back-translation and adaptation of the scale into Brazilian Portuguese [here named "Escala de Confusão, Alvoroço e Ordem no Sistema familiar" (CAOS)], assessed by 5 judges. In Study 2, we conducted an exploratory factor analyses (EFA) to determine the scale's factor structure (N = 180 adults). In Study 3, we carried out confirmatory factor analyses (CFA) to confirm the internal validity of the scale, along with complete structural equation modeling to explore convergent validity in another sample (N = 239 adolescents). RESULTS: The CAOS scale displayed content validity, and the EFA and CFA showed a unifactorial structure (with some scale adjustments) with an acceptable fit. The family chaos latent factor was associated with externalizing symptoms and perceived stress in adolescents. CONCLUSION: Overall, the Brazilian version of the scale presented evidence of construct, internal, and concurrent validity that indicate its usefulness in Brazil.
