Establishing Evidence for Internal Structure Using Exploratory Factor Analysis

EEG Dataset for the Recognition of Different Emotions Induced in Voice-User Interaction

Electroencephalography (EEG)-based open-access datasets are available for emotion recognition studies, where external auditory/visual stimuli are used to artificially evoke pre-defined emotions. In this study, we provide a novel EEG dataset containing the emotional information induced during a realistic human-computer interaction (HCI) using a voice user interface system that mimics natural human-to-human communication. To validate our dataset via neurophysiological investigation and binary emotion classification, we applied a series of signal processing and machine learning methods to the EEG data. The maximum classification accuracy ranged from 43.3% to 90.8% over 38 subjects and classification features could be interpreted neurophysiologically. Our EEG data could be used to develop a reliable HCI system because they were acquired in a natural HCI environment. In addition, auxiliary physiological data measured simultaneously with the EEG data also showed plausible results, i.e., electrocardiogram, photoplethysmogram, galvanic skin response, and facial images, which could be utilized for automatic emotion discrimination independently from, as well as together with the EEG data via the fusion of multi-modal physiological datasets.

"I Would Have My Children Participate IF …": Perceptions of Canadian Caregivers Towards School Food Programs

Purpose: The Canadian federal government has expressed an intention to work with provinces and territories to develop a national school food program (SFP). This study aimed to explore caregivers' perception of attributes important to include in a future SFP.Methods: An online cross-sectional survey was conducted. Fifteen elementary schools from high, medium, or low median income neighbourhoods in Saskatoon were invited to participate. School principals sent a survey link to students' caregivers. The 37-item survey included an item with 15 statements asking caregivers to rate the importance of various components of a SFP. Descriptive statistics and exploratory factor analysis were conducted.Results: A total of 510 caregivers completed the survey (response rate of 52%). The factor analysis indicated four key components of a future SFP: (1) learning opportunities on growing and preparing food, (2) offering healthy food following Canada's Food Guide, (3) affordability of the meals offered, and (4) cultural adaptability of the meal program. Over 90% of caregivers thought providing healthy meals and ample time to eat meals to be very important.Conclusion: Our results indicate caregivers support multicomponent meal programs that, along with providing nutritious food, help children build healthy habits and sustainable food systems. These findings will help dietitians understand caregivers' perspectives to inform the design of a national SFP.

Evaluating the psychometric structure of the Hamilton Rating Scale for Depression pre- and post-treatment in antidepressant randomised trials: Secondary analysis of 6843 individual participants from 20 trials

BACKGROUND

The 17-item Hamilton Rating Scale for Depression (HRSD-17) is the most popular depression measure in antidepressant clinical trials. Prior evidence indicates poor replicability and inconsistent factorial structure. This has not been studied in pooled randomised trial data, nor has a psychometrically optimal model been developed.

AIMS

To examine the psychometric properties of the HRSD-17 for pre-treatment and post-treatment clinical trial data in a large pooled database of antidepressant randomised controlled trial participants, and to determine an optimal abbreviated version.

METHOD

Data for 6843 participants were obtained from the data repository Vivli.org and randomly split into groups for exploratory (n = 3421) and confirmatory (n = 3422) factor analysis. Invariance methods were used to assess potential sex differences.

RESULTS

The HRSD-17 was psychometrically sub-optimal and non-invariant for all models. High item variances and low variance explained suggested redundancy in each model. EFA failed at baseline and produced four item models for outcome groups (five for placebo-outcome), which were metric but not scalar invariant.

CONCLUSIONS

In antidepressant trial data, the HRSD-17 was psychometrically inadequate and scores were not sex invariant. Neither full nor abbreviated HRSD models are suitable for use in clinical trial settings and the HRSD's status as the gold standard should be reconsidered.

Menstrual poverty scale: reliability and validity study

The tendency toward poverty in the globalizing world significantly affects women. Unlike men, women have mandatory expenses every month. Especially poor women have difficulty in accessing to the hygienic products they need during the menstrual period. That is why, this study aims to develop a measurement tool that can effectively and widely assess women's menstrual poverty. This study is a methodological study that evaluates the psychometric properties of the scale. The study included 420 women living in a middle-income province in the north of Türkiye between April - July, 2023. The data were collected using the Menstrual Poverty Scale, and the items on the scale were developed based on a review of existing literature and expert opinions (CVI = 0.85-0.95). The sample was divided into two parts. It was made exploratory factor analysis and confirmatory factor analysis. Before conducting the study, an ethics committee decision and informed consent of the women were obtained. The collected data were analyzed using the SPSS 23 and AMOS 23 programs. The EFA revealed a structure consisting of 13 items and four factors. The four factors considered were as follows; access to hygiene products, quality of life, embarrassment, and receiving information, and education about menstruation. The item factor loadings varied from 0.46 to 0.91. The Cronbach's alpha coefficient was determined to be 0.69. The corrected item-total correlations for the scale items ranged from 0.62 to 0.84. According to the confirmatory factor analysis, the structural equation modeling results of the Menstrual Poverty Scale were found to be meaningful (p = .000; RMSEA 0.64; CMIN/Df 1.70). It is suggested to conduct validity and reliability studies in different cultures by applying the scale to women from different cultural backgrounds.

Psychometric Properties of the Turkish Version of the Abiloco: Factor Analysis

The ABILOCO is a questionnaire measuring mobility in stroke patients. The aim of the study was to evaluate the psychometric properties of the ABILOCO-Turkish. One hundred forty stroke patients were included. Thirteen items were rated according to 3 levels: difficult, easy, and impossible. The construct validity of the ABILOCO-Turkish was investigated using exploratory and confirmatory factor analysis. The reliability of the ABILOCO-Turkish was investigated through internal consistency approaches and test-retest reliability. The ABILOCO-Turkish was compared with the Timed Up & Go (TUG) test and the Berg Balance Scale for validity. The scale was repeated 1 week later for test-retest reliability. The Cronbach's alpha value calculated was 0.96 and item-total score correlations were between 0.464 and 0.899. The intraclass correlation coefficient (ICC) calculated for test-retest reliability was 0.989. According to the results, the ABILOCO-Turkish is highly correlated with the TUG (r: -0.830, p < 0.001) and the Berg Balance Scale (r: 0.919, p < 0.001). The exploratory factor analysis of the ABILOCO-Turkish showed that it is unidimensional, with this factor explaining 66.56% of the variance, and the construct validity was proven by confirmatory factor analysis. The Turkish version of the ABILOCO is a reliable and valid scale for evaluating mobility in stroke patients.

The mechanisms of nature-based therapy on depression, anxiety, stress, and life satisfaction: examining mindfulness in a two-wave mediation model

Background

Nature-based therapy (NBT), which centers around engaging in activities within natural surroundings, has consistently demonstrated therapeutic benefits for mental health. While NBT highlights the potential of nature as a therapeutic resource for promoting mental health, there is limited knowledge regarding its underlying mechanisms.

Methods

Two hundred seventy-six Korean participants (204 women, mean age = 54.99 ± 23.25 years) participated in a 30-session gardening program held twice weekly for 15 weeks. Structural equation modeling with a two-wave autoregressive cross-lagged model was used to investigate the mediating effects of mindfulness.

Results

NBT significantly improved the mean scores of all psychological variables. The mediation model was partially confirmed, with mindfulness at post-intervention (T2) mediating the relationship between baseline (T1) depression and anxiety and post-intervention (T2) life satisfaction. However, no significant indirect effect was observed between the path from stress (T1) to life satisfaction (T2).

Conclusion

Mindfulness is a crucial component for improving mental health outcomes. This study underscores the need to prioritize and emphasize mindfulness practices in NBT.

Development and initial psychometric evaluation of a COVID-related psychosocial experiences questionnaire for cancer survivors

BACKGROUND

Cancer survivors are at elevated risk of psychological problems related to COVID-19, yet no published measure adequately assesses their psychosocial experiences during the pandemic.

PURPOSE

Describe the development and factor structure of a comprehensive, self-report measure (COVID-19 Practical and Psychosocial Experiences questionnaire [COVID-PPE]) assessing the pandemic's impact on US cancer survivors.

METHODS

The sample (n = 10,584) was divided into three groups to assess COVID-PPE factor structure by conducting: (1) initial calibration/exploratory analysis of the factor structure of 37 items (n = 5070), (2) confirmatory factor analysis of the best-fitting model (36 items after item removal; n = 5140), and (3) post-hoc confirmatory analysis with an additional six items not collected in the first two groups (42 items; n = 374).

RESULTS

The final COVID-PPE was divided into two sets of subscales, conceptualized as Risk Factors and Protective Factors. The five Risk Factors subscales were labeled Anxiety Symptoms, Depression Symptoms, Health Care Disruptions, Disruptions to Daily Activities and Social Interactions, and Financial Hardship. The four Protective Factors subscales were labeled Perceived Benefits, Provider Satisfaction, Perceived Stress Management Skills, and Social Support. Internal consistency was acceptable for seven subscales (αs = 0.726-0.895; ωs = 0.802-0.895) but poor or questionable for the remaining two subscales (αs = 0.599-0.681; ωs = 0.586-0.692).

CONCLUSIONS

To our knowledge, this is the first published self-report measure comprehensively capturing psychosocial impact-both positive and negative-of the pandemic on cancer survivors. Future work should evaluate predictive utility of COVID-PPE subscales, particularly as the pandemic evolves, which may inform recommendations for cancer survivors and facilitate identification of survivors most in need of intervention.

Validation of Hospital Anxiety and Depression Scale in an Indonesian population: a scale adaptation study

OBJECTIVE

This study aims to adapt the English-language Hospital Anxiety and Depression Scale (HADS) to the Indonesian language and evaluate the validity and reliability of the adapted version (ie, HADS-Indonesia).

DESIGN

A cross-sectional study was conducted between June and November 2018. First, a translation and back-translation process was conducted by a committee consisting of the researchers, a psychiatrist, a methodology consultant and two translators. Face and convergent validity and test-retest reliability evaluations were conducted. Next, structural validity and internal consistency analyses were performed. An intraclass correlation coefficient (ICC) test evaluated the scale's test-retest reliability. A Spearman's rank correlation coefficient was calculated to evaluate the correlation between HADS-Indonesia and Zung's Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) for convergent validity evidence. Next, a structural validity analysis using exploratory factor analysis (EFA) and an internal consistency evaluation based on Cronbach's alpha was conducted.

SETTING

This study was conducted in three villages in Jatinangor subdistrict, Sumedang Regency, West Java province, Indonesia; the villages were chosen based on their profiles.

PARTICIPANTS

A total of 200 participants (male: n=91, 45.50% and female: n=109, 54.50%), with a mean age of 42.41 (14.25) years, were enrolled in this study using a convenience sampling method. The inclusion criteria were age ≥18 years old with basic Indonesian language literacy.

RESULTS

The overall HADS-Indonesia's ICC value was 0.98. There was a significant positive correlation between HADS-Indonesia's anxiety subscale and Zung's SAS (r_s=0.45, p=0.030) and between the depression subscale of HADS-Indonesia and Zung's SDS (r_s=0.58, p<0.001). The Kaiser-Meyer-Olkin statistics (KMO) (KMO=0.89) and Bartlett's test of sphericity (χ²(91, N=200)=1052.38, p<0.001)) indicated an adequate number of samples for EFA. All items' commonality was >0.40 and the average inter-item correlation was 0.36. EFA yielded a 2-factor solution explaining 50.80% (40.40%+10.40%) of the total variance. All items from the original HADS were retained, including its original subscales. The adapted HADS-Anxiety subscale consisted of seven items (alpha=0.85), and the HADS-Depression subscale consisted of seven items (alpha=0.80).

CONCLUSIONS

HADS-Indonesia is a valid and reliable instrument for use in the general population of Indonesia. However, further studies are warranted to provide more sophisticated validity and reliability evidence.

Investigating smart city adoption from the citizen's insights: empirical evidence from the Jordan context

This study aims to investigate the factors that perceive citizens' intention to adopt smart city technologies in the Arab world. A self-administered questionnaire that included 312 end users as citizens in Amman, Jordan's capital city, was used in this study. This study uses advanced statistical techniques to test an expanded technology acceptance model (TAM) that incorporates the determinants of perceived usefulness, perceived ease of use, security and privacy, ICT infrastructure and inadequate Internet connectivity, social influence, and demographic profiles. Based on the results, perceived ease of use and ICT infrastructure and Internet connectivity showed positive association with the intention of citizens to adopt smart city services in Jordan. By recognizing the factors that predict citizens' adoption of smart city services, this study presents some theoretical implications and practical consequences related to smart city service adoption.

Threat by Association, Islamic Puritanism and Conspiracy Beliefs Explain A Religious Majority Group’s Collective Protest Against Religious Minority Groups

This article addresses the question of why members of a majority group, despite their more powerful status, may protest against low-power minority groups. The present study addressed this question in the context of immanent intergroup relations between Muslims, as the majority group, and non-Muslims, as the minority group, in Indonesia. It is argued that at the core of such collective protests is a threat by association, a perception of the majority group members that the minority groups are in league with the West which threatens the existence of Muslims worldwide. Based on data collected using a survey questionnaire from Indonesian Muslims ( N = 418) this study tested a hypothesised model using threat by association posed by the minority groups, Islamic puritanism and beliefs relating to western conspiracy to predict collective protests and intolerant intentions against non-Muslim minorities in Indonesia by using MPlus version 7.0. The hypothesised model found empirical support. The relationship between threat by association and Islamic puritanism with collective protests was mediated by Western conspiracy beliefs. It was also found that support for collective protests got translated into majority group members’ religious intolerant intentions against the people belonging to the non-Muslim minority groups. The article discusses the theoretical implications and research limitations of these empirical findings.

Modeling the Capabilities of High-Performing Project Management Offices in General Contracting Companies

The contemporary literature emphasizes a need to delve into how project management offices (PMOs) can be effectively operated in construction organizations by embedding integrated project management rather than relying on stand-alone project controls. However, capabilities for running high-performing PMOs in this complex industry are still unknown to this growing body of knowledge, which is considered a barrier to the realization of their full potential. To address this gap, the current research explores a factor structure for core capabilities using a cross-validation method with survey data from 395 experts in general contracting organizations. The results revealed that the five-factor measurement model encompasses constructs of competent human resources and supportive culture, strategic alignment, delivery support, knowledge management, and leveraging organizational capabilities. This study extends the current literature by establishing a new measurement model explaining the dimensionality of PMO capabilities.

Measuring patient compliance with wearing graduated compression stockings

BACKGROUND

Patient compliance is an essential precondition for assessing the effectiveness of graduated compression stockings (GCS). However, patient compliance with use of GCS has not received sufficient attention. Only a few clinical studies have explicitly evaluated patients' adherence to GCS therapy, and the instruments used to measure patient compliance have either not been well adapted to daily use or lacked scientific development techniques. Most instruments have focused on "wear or not wear" or "how long did you wear" questions, which do not consider all the perspectives on patient compliance. In the present study, we used scale development and validation steps to create a self-reported questionnaire to measure patients' compliance with wearing GCS.

METHODS

We designed a questionnaire to measure compliance with wearing GCS among patients who had undergone invasive treatment of superficial varicose veins of the lower extremities. The initial questions were determined after a literature review and interviews with experts and patients. Reliability was evaluated using the Delphi method with expert judges, pretesting, Cronbach's alpha, and test-retest reliability. Exploratory and confirmatory factor analyses were used to test the questionnaire's validity.

RESULTS

The developed questionnaire had 11 questions with the responses rated from 1 to 4 and included three factors: compliance with correct GCS wearing methods, compliance with GCS wearing cautions, and compliance with seeking advice. The Cronbach alpha for the overall questionnaire was 0.853 (factor 1, 0.934; factor 2, 0.803; factor 3, 0.789), its content validity was good, and the factor structure fitted the data well.

CONCLUSIONS

We have presented our initial version of the questionnaire for patients who have undergone invasive treatment of superficial varicose veins of the lower extremities. The questionnaire can be used to evaluate patient compliance with wearing GCS thoroughly and effectively. However, further work is still required to maximize its reliability and validity for its use in daily practice in the future.

Physiological and affective responses to green space virtual reality among pregnant women

BACKGROUND

Benefits of green spaces on stress reduction have been shown in previous studies. Most existing studies to date have focused on the general population. However, there is a lack of understanding of physiological mechanisms underlying the beneficial effects of green space among special populations, such as pregnant women.

OBJECTIVES

To examine physiological and affective responses to green space on stress recovery among pregnant women, using simulated green space exposure through virtual reality (VR).

METHODS

We recruited 63 pregnant women between 8 and 14 weeks' gestational age for a laboratory experiment. Participants were randomly assigned to view one of three, 5-min, VR videos of an urban scene with different green space levels (i.e., non-green, moderate, and high) after a laboratory stressor, the Trier Social Stress Test. Physiological stress responses were measured via changes in blood pressure, heart rate, skin conductance level, salivary alpha-amylase, and salivary cortisol. Affective response was measured using the Positive and Negative Affect Scale.

RESULTS

We found that visual exposure to a green space environment in VR was associated with both physiological and affective stress reduction among pregnant women, including lower systolic blood pressure [-4.6 mmHg, 95% confidence interval (CI): -8.8, -0.4], reduced salivary alpha-amylase concentration (-1.2 ng/ml, 95% CI: -2.2, -0.2), improved overall positive affect (score: 6.6, 95% CI: 0.3, 13.0) and decreased negative affect of anxiety (score: -2.6, 95% CI: -5.19, -0.04) compared to non-green space environment. Exposure to high green space environment in park-like setting had the strongest impacts on stress recovery.

CONCLUSION

This study demonstrated that virtual green space exposure could effectively ease stress and improve mental health and well-being during pregnancy. Even a short immersion in VR-based green space environment may bring health benefits, which has significant implications for pregnant women when access to an actual nature may not be possible.

Development and Psychometric Validation of a Novel Self-Report Measure of ICD-11 Gaming Disorder

Video game use is associated with addiction-like behaviors in 6 to 15.6 percent of video game players. There were no formal diagnostic criteria for video game addiction until gaming disorder (GD) was added to the International Classification of Diseases 11th Edition (ICD-11), and there are no published instruments designed to diagnose GD. The aims of the current study were to develop a self-report measure of GD (using the Lee Morrell Gaming Disorder Questionnaire [LMGDQ]) and test its factor structure, reliability, validity, and relationships with participant demographic characteristics. Participants included 3,481 adult video game players (M = 25.08, SD = 7.02; 79.8 percent cisgender male; 77.4 percent Caucasian) who completed an online survey. Factor analyses suggested retaining 14 items and indicated the presence of two factors. The scale had excellent reliability (α = 0.919), and LMGDQ scores were positively correlated with existing scales measuring problematic video game use as well as video game use and age, p values <0.01. Participants who were Asian and Asian American, cisgender men, single and dating, unemployed, had completed some high school or their GED, and who played massively multiplayer online role-playing games the most reported significantly greater LMGDQ scores, p values <0.05. Results suggest that the LMGDQ is a psychometrically sound and valid measure of GD.

Assessing Suicidal Ideation in Young People With Depression: Factor Structure of the Suicidal Ideation Questionnaire

Evaluating suicidal ideation in young people seeking mental health treatment is an important component of clinical assessment and treatment planning. To reduce the burden of youth suicide, we need to improve our understanding of suicidal ideation, its underlying constructs, and how ideation translates into suicidal behaviour. Using exploratory factor analysis, we investigated the dimensionality of the Suicidal Ideation Questionnaire (SIQ) among 273 participants aged 15-25 with Major Depressive Disorder. Area under the receiver operating characteristic curve (AUROC) analysis was used to explore associations between latent factors and actual suicidal behaviour. Findings suggested that the SIQ assesses multiple factors underlying suicidal ideation. AUROC analyses demonstrated that latent factors relating to both active and passive suicidal ideation predicted past-month suicidal behaviour and suicide attempt. These findings contribute to an improved understanding of the complexities of suicidal ideation and relationships with suicidal behaviour in young people with depression.

Development and Initial Validation of the Multidimensional Sense of Emptiness Scale

The present study describes the development and initial validation of the Multidimensional Sense of Emptiness Scale, a measure based on a theoretically and empirically grounded conceptualization of emptiness. In the first sample ( n = 541), an exploratory factor analysis yielded three factors, Sense of Inner Emptiness, Sense of Absence of Relatedness, and Sense of Meaninglessness, explaining 82.8% of the variance with 13 items. In an additional sample ( n = 212), a confirmatory factor analysis supported this three-factorial solution's stability. Furthermore, all subscales were significantly related to a single, second-order factor. In the total sample ( N = 753), subscale and full-scale items offered evidence of satisfactory internal consistency and convergent validity. We discuss study limitations and implications for counseling practice, advocacy, education, training, and research.

Development and Validation of Parental Support Scale of Children’s Sports Training in China: Socio-Ecological Approach

Objectives

To promote Chinese children participation in sports training and acquisition of sports skills, we combined a social ecological research framework with parental support to develop the Parental Support for Children’s Sports Training Scale (PSCSTS).

Methods

The scale was initially developed based on literature review, group interviews, and expert evaluations. A complete reliability and validity test was conducted on 1,594 parents of primary and secondary schools in Shanghai.

Results

The PSCSTS has 37 questions, and exploratory factor analysis has formed 10 factors: policy support, parents’ financial support, community support, media support, sports development, school activity participation, parents’ exercise habits, training quality support, development of school sports activities, learning skills. The higher-order models constructed by validated factor analysis fit well (χ²/df = 2.130, RMSEA = 0.038, SRMR = 0.042, GFI = 0.911, CFI = 0.928). The Parents of children of different sexes have measurement invariance in the PSCSTS.

Conclusion

The PSCSTS developed in this study based on a social-ecological framework has high reliability and validity, and can be used as a comprehensive measure of parental support for their children’s sports training.

Nursing Warmth Scale (NWS): Development and empirical validation

Objective: To construct and validate the Nursing Warmth Scale (NWS) through the development of a standardized measurement of nurses' warmth, perceived from the perspective of patients, and identify the behaviors and factors associated with this feeling of warmth. Materials and methods: The NWS was developed following the scale construction methodology under a triphasic model. The construction of items was elaborated based on the results of a previously published integrative review that consolidated the construct and the related variables. A qualitative phase was also incorporated to evaluate the latent variable. Content validity was assessed with 10 expert judges. An item try-out was conducted with 476 patients in health institutions. Exploratory factor analysis —through the common factor method and oblique rotation— was used for the item reduction process. Results: The construct “Nursing Warmth” was established after the theoretical and empirical phases of the study. The literature review and interviews with 23 patients and 25 nursing professionals provided a set of behaviors divided into 2 categories: verbal and nonverbal behaviors. Exploratory factor analysis allowed identifying 5 factors and 35 items. The reliability was estimated through Cronbach's alpha. The identified factors are: F1-Nonverbal connection-relationship with the other (0.943), F2-Empathy (0.909), F3-Verbal connection-relationship with the other (0.914), F4-Inclusion (0.858), and F5-Confidence (0.852). The Tucker-Lewis Index was 0.901. Conclusions: The NWS demonstrates evidence of reliability and validity. This tool may be useful in clinical settings and for teaching and research addressing interpersonal nursing skills.

Arabic version of the Missed Nursing Care Survey: Validity and reliability

AIM

To explore the validity and reliability of the Missed Nursing Care Survey after translating it into the Arabic language.

METHODS

We employed a cross-sectional design. We recruited 260 Jordanian nurses, and data were collected between May and July 2020. Translation, acceptability, construct, convergent, discriminant validity and reliability were investigated.

RESULTS

The factor analysis showed an adequate fit (three subscales) between the proposed missing care survey model and the observed data. This model reflected the survey's construct, convergent and discriminant validity, explaining 58.88% of the variance collectively. Confirmatory factor analyses showed adequate goodness-of-fit results (goodness of fit index = 0.91, comparative fit index = 0.94, increment fit index = 0.94, Tucker Lewis index = 0.92 and root mean square error of approximation = 0.06). The total Cronbach alpha and composite reliability achieved the criterion for all constructs in this survey.

CONCLUSION

This Arabic version of the Missed Nursing Care Survey achieved the required level of validity and reliability. Measuring missed care and its reasons may help to improve quality of health services and assist nurse managers in designing appropriate interventions to reduce it. Adoption of culturally acceptable instruments by health-care policymakers may support patient safety.

Adaptation and Validation of the Tuberculosis Related Stigma Scale in Portuguese

Objective: To adapt and validate the Tuberculosis Related Stigma Scale (TRSS) in European Portuguese. Materials and method: A methodological study in a sample of 204 individuals being treated for pulmonary tuberculosis in Portuguese Pulmonary Diagnostic Centers, with at least one month of treatment or in follow-up. The evaluation process of linguistic and conceptual equivalence involved translation, the consensus among judges, back-translation, semantic validation, and pre-testing of the TRSS. The scale’s psychometric properties were assessed by verifying the reliability and validity of the results and calculating Cronbach’s alpha coefficient and the exploratory factor analysis of principal components, with Varimax rotation of the scale items. Results: The Portuguese version of the TRSS has a Cronbach’s alpha coefficient of 0.94 and has 23 items distributed in two dimensions: “Community’s perspectives on tuberculosis” (11 items) and “Person’s perspectives on tuberculosis” (12 items). Its psychometric characteristics ensure adequate reliability and validity for the Portuguese population. Conclusions: The TRSS is a valid and reliable instrument to assess stigma in people with pulmonary tuberculosis and, to date, the only scale validated in this domain for the Portuguese population, which allows nurses to make an integrated intervention.

The cross-cultural adaptation and factor analysis of the Turkish version of Iconographical Falls Efficacy Scale Long Version

BACKGROUND

Iconographical Falls Efficacy Scale (Icon-FES) is the first visual scale for fear of falling. Unlike the others, Icon-FES, including 30 items offers a unique perspective to assess the fear of falling by providing more precise contexts.

OBJECTIVES

The study aimed to introduce the 30-item Icon-FES, the first visual content fear of falling scale, into Turkish and to explore its psychometric properties.

METHODS

First, the Turkish language validity of Icon-FES was ensured by following the forward-backward translation protocol. A total of 150 older adults independent in their daily living activities were included in the study. Falls Efficacy Scale International (FES-I) and Activities Specific Balance and Confidence Scale (ABC), which are frequently preferred in the literature for the same purpose, were used to provide the criterion validity of the scale. The exploratory factor analysis method was utilised for the construct validity of the scale.

RESULTS

Factor analysis revealed a two-factor structure. 52.22% of the total variance was explained with single-factor analysis. In the criterion validity analysis, while there was a strong positive correlation between Icon-FES and FES-I (r = 0.910, p < 0.01), a strong negative correlation was found between Icon-FES and ABC (r = -0.887, p < 0.01). The Cronbach Alpha value for the internal consistency of the scale was calculated as 0.965. The intraclass correlation coefficient between two measurements performed one-week interval was found to be 0.985 (p < 0.001).

CONCLUSION

The study showed that Icon-FES is a valid, reliable and rapid result assessment tool for community-dwelling older adults without cognitive dysfunction.

Psychometric properties and clinical utility of the executive function inventory for children and adolescents: a large multistage populational study including children with ADHD

Executive functions (EF) are a set of high order mental abilities that regulate cognition, emotions, and behavior. This study aims to report the construction and validation of a rating scale instrument for EF in children and adolescents aged from 5 to 18 years (EFICA), as well as to report the results of a comparison between children with ADHD and their peers without it. Thus, we conducted a population-based cross-sectional study relying on a sample composed of 3,284 typical children and adolescents accessed to study the psychometric properties of the parents' inventory (EFICA-P) and the teacher's inventory (EFICA-T) within a Structural Equation Modeling framework (SEM). Exploratory and confirmatory analyses were fitted, as well as the Cronbach's alpha and the McDonald's omega reliability indices. The known-groups method was carried out by independent Welch t-tests between untreated ADHD children and their peers. We concluded that the parents' inventory is composed of three dimensions (Cool Index 1, Cool Index 2, and Hot Index): χ² (1,649) = 4,607.852 p < .01, CFI = .965, TLI .963, RMSEA = .053, whereas the teachers´ inventory is composed of two dimensions (Cool Index and Hot Index): χ² (1,273) = 5,158.240, p < .01, CFI = .991, TLI = .991, RMSEA = .077. The internal consistency of both inventories was >.9. Significant differences between the ADHD groups were found in all domains accessed. These findings indicate that both inventories have a high degree of validity regarding their internal structures, as well as supporting their clinical utility.

Psychometric Properties of the Korean Family Reported Outcome Measure for Family Members of Patients With Acquired Brain Injury

ABSTRACT

BACKGROUND: Acquired brain injury (ABI) affects not only survivors but also their family members' quality of life in various ways. The Family Reported Outcome Measure (FROM-16), a self-reported instrument, has been developed to evaluate the impact of diseases on the lives of family members of patients. This study aimed to assess the reliability and validity of the Korean FROM-16 for family members of individuals with ABI. METHODS: A total of 200 family members of patients with ABI in South Korea participated in this study. Internal consistency was assessed using Cronbach α. To establish the validity, we evaluated the semantic equivalence, content, known-group, conduct, concurrent, and convergent validity of the Korean FROM-16. For exploratory factor analysis, common factor analysis with oblique rotation, parallel analysis, an eigenvalue greater than 1.0, and a scree plot were used. RESULTS: Exploratory factor analysis revealed 2 factors for the 16 items, which explained 67.4% of the total variance. Concurrent validity was established by comparison with the Korean World Health Organization Quality of Life Scale Brief (r = -0.57), and regarding the convergent validity, the Korean FROM-16 score positively correlated with the Korean Neurobehavioral Functioning Inventory. Known-group validity was confirmed by showing that family members with advanced age, the burden of caring, and insufficient income, as well as spouses, had a statistically higher score in the Korean FROM-16. Cronbach α was .92, indicating high internal consistency reliability. CONCLUSION: The Korean FROM-16 is a valid and reliable instrument for evaluating the impact of diseases on family members of individuals with ABI in South Korea.

Psychometric Validation and Translation of Religious and Spiritual Measures

Scale development, validation, and translation are complicated and often arduous procedures that involve considerable cost, time, personnel, and skills necessary to perform the complex statistical analyses required. The need to follow a standard procedure when developing new scales and translating old scales into new languages is essential in order to ensure that researchers accurately measure what they are claiming to measure. Well-designed scales form the foundation for much of the quantitative research conducted today in the psychological, social, behavioral and physical health sciences. This is also true for studies that examine the relationship between religiosity and/or spirituality (R/S) and health. The relationship between R/S and health is a complex one, requiring the development of measures that comprehensively, sensitively, reliably, and accurately measure R/S. As with many other emerging areas in the health sciences, quantitative measurement using psychometrically sound scales and the translation of existing scales into other languages is essential for advancement of the field of religion and health. In this article, a standard procedure for developing, validating, and translating multi-item scales is described.

Graduate training during the COVID-19 pandemic: North American genetic counseling students' challenges, intolerance of uncertainty, and psychological well-being

The COVID-19 pandemic has upended genetic counseling (GC) graduate students' lives, as they have been forced to transition, manage, and acclimate to life during a pandemic. The current study is a first step in understanding their lived experiences during this historic, global event. We investigated academic and personal challenges, intolerance of uncertainty, and psychological well-being of GC students (n = 248) who trained during the pandemic (GC-COV cohort) and those who did not (GC-NoCOV cohort). Participants completed an online survey (July-September 2020) that used validated measures of Intolerance of Uncertainty and Psychological Well-Being. To assess the academic and personal challenges students experienced during GC graduate training, we developed a 43-item measure. Principal axis factoring of the items revealed categories of challenges related to the following: Academic & Professional Development, Self-Regulation & Resilience, Institutional & Program Leadership, and Financial Stability. There was no cohort difference in Psychological Well-Being. Linear mixed-effects modeling showed significant cohort differences in challenges. Multiple linear regression analyses revealed that the GC-COV cohort's Psychological Well-Being was statistically significantly predicted by Institutional & Program Leadership challenges (p = .029), Self-Regulation & Resilience challenges (p = .013), and Intolerance of Uncertainty (p = .010). For the GC-NoCOV cohort, the statistically significant predictor of Psychological Well-Being was Self-Regulation & Resilience challenges (p = .029). Our findings demonstrate that GC students training during the COVID-19 pandemic have experienced various personal, academic, and psychological disruptions and highlight a need to develop resources and implement interventions supporting students' academic development and psychological well-being.

The Rowing-Specific Reinvestment Scale

This research project aimed to develop and validate a rowing-specific reinvestment scale. In Study 1, a 24-item questionnaire was developed and the content validity was assessed using experts (N = 7) and pilot-tested in rowers (N = 24). Next, rowers (N = 282) completed the questionnaire with the remaining items, and exploratory factor analysis (EFA) was conducted. This further reduced the number of items and revealed two factors, rowing specific conscious motor processing (RS-CMP) and movement self-consciousness (RS-MSC). In Study 2, rowers (N = 270) completed the scale that was evaluated using confirmatory factor analysis (CFA). Moreover, the construct validity of the scale was investigated by asking them to complete measures of movement-specific reinvestment, perceived performance, self-consciousness, and state anxiety. Actual performance was also determined based on their race finishing position. Study 1 EFA resulted in a 2-factor model with six items assessing RS-CMP and six items assessing RS-MSC. Study 2 supported the factor structure of scale; CFA indicated an acceptable model fit with good internal consistency. Content validity was also supported, with evidence of concurrent, convergent, discriminant, and predictive validity. In conclusion, these studies provided good initial evidence for the validity and reliability of the RSRS.

Job satisfaction and leadership behavior brief measures: a development and validation study

Purpose

Job satisfaction and leadership behavior are recognized by the organizational world as fundamental elements that influence the overall effectiveness of a company. However, as the first step for an adequate intervention on any of these variables, it is the evaluation. The purpose of this paper is to develop and validate two brief measures on job satisfaction and leadership behavior.

Design/methodology/approach

The sample was made up of 246 workers located in Bogota, Colombia. The study was an instrumental research. To collect validity evidence, the internal structure and the relationship with other variables were used. For the evaluation of equity, the differential item functioning was analyzed according to the sex of the participants. Reliability was estimated through the ordinal omega coefficient.

Findings

Both brief measures presented a unifactorial structure, where job satisfaction was measured by five items and leadership behavior by four items. On the other hand, only one item of leadership behavior showed differential item functioning; however, its magnitude was trivial. Also, convergent and discriminant evidence was provided for both measures, and the reliability levels were adequate.

Originality/value

The measures developed represents an effort to briefly measure job satisfaction and leadership behavior. Likewise, it constitutes two of the few instruments to measure job satisfaction and leadership behavior in Latin American, representing a good alternative for the measurement of the referred constructs in an organizational context.

The Development of the Love and Respect Marriage Scale

The constructs of love and respect have been known to be essential ingredients contributing positively to marital satisfaction, but to-date they have mostly been measured using separate scales. However, given the overlap between both constructs this study set out, using self-report methodologies, to develop a comprehensive scale which measures both love and respect known as The Love and Respect Marriage Scale. Using a nonclinical community Singapore sample (n = 400), an initial item pool was developed, and through exploratory factor analysis, a robust factor structure emerged that consisted of eight subscales and 46 items. This factor structure was shown to be a consistent and cross-culturally acceptable model using samples from USA, n = 396, South Africa, n = 390, Nigeria, n = 364, and India, n = 306. Good reliability values were achieved. Construct, convergent, divergent, and incremental validity were also demonstrated as comparisons were made with shorter established marriage scales. Implications and advantages of a longer marital scale were discussed.Supplemental data for this article is available online at https://doi.org/10.1080/0092623X.2021.1963362 .

Environmental heat-related health symptoms among community in a tropical city

Due to the changing climate, more frequent and prolonged heatwaves are expected to have a catastrophic consequence on urban human settlement. In tropical cities such as Kuala Lumpur (KL), the quality of the urban environment is made worse by urban heat island (UHI) phenomena due to poor urban planning practices. The prolonged exposure to urban heat is hypothesized to influence human health and well-being, especially in tropical urban areas with high population density. Therefore, a study was conducted to understand the association of urban heat stress with physical, psychosomatic and psychological (PPP) health symptoms within a tropical urban setting. Continuous urban microclimate monitoring is conducted using an automated weather station to define the level of heat stress in the study area expressed as Physiological Equivalent Temperature (PET). A cross-sectional approach is used to identify heat-related health symptoms experienced by the urban population. Through exploratory factor analysis, a total of 38 PPP health symptoms are reduced into 8 heat-related health clusters which are sensory organ pain, heat-related illnesses, cardiopulmonary, pain, fatigue, anxiety, somatization, and depression-related symptoms. Heat stress was found to significantly affect psychosomatic pain (p = 0.016) as well as psychological anxiety (p = 0.022) and somatization (p = 0.041) related symptoms. Other health clusters were not significantly associated with heat stress. More studies are needed to unravel the influence of confounding factors and the long-term impact of urban heat on the health and well-being of the urban population in a tropical city.

Adaptation of the COV19-QoL Scale to Turkish culture: Its psychometric properties in diagnosed and undiagnosed individuals

This study was conducted to adapt the COV19-QoL scale to Turkish culture and to examine its psychometric properties in individuals diagnosed with and without COVID-19. A total of 1069 people aged between 18 and 65 years participated in the study. The COV19-QoL_TR scale has six items, and it was confirmed to be one-dimensional in the Turkish sample (participants diagnosed with and without COVID-19 and the general population). Participants' perceived quality of life and levels of anxiety and depression were the most affected areas and their physical and mental health levels were the least affected by the pandemic.

Development and Validation of a Perceived Barriers to Physical Activity Scale for Low-Income Adolescents

BACKGROUND

Low-income adolescents' physical activity (PA) levels fall below current recommendations. Perceived barriers to physical activity (PBPA) are likely significant predictors of PA levels; however, valid and reliable measures to assess PA barriers are lacking. This manuscript describes the development of the PBPA Survey for Low-Income Adolescents.

METHODS

A mixed-method approach was used. Items identified from the literature and revised for clarity and appropriateness (postcognitive interviews) were assessed for test-retest reliability with 74 adolescents using intraclass correlation coefficient. Items demonstrating low intraclass correlation coefficients or floor effects were removed. Both exploratory factor analysis and confirmatory factor analysis analyses (n = 1914 low-income teens) were used to finalize the scale; internal consistency was assessed by Cronbach's alpha. Concurrent validity was established by correlating the PBPA with the PA questionnaire for adolescents using a Spearman correlation.

RESULTS

The exploratory factor analysis yielded a 38-item, 7-factor solution, which was cross-validated by confirmatory factor analysis (comparative-fit index, nonnormed fit index = .90). The scale's Cronbach's alpha was .94, with subscales ranging from .70 to .88. The PBPA Survey for Low-Income Adolescents' concurrent validity was supported by a negative PA questionnaire for adolescents' correlation values.

CONCLUSION

The PBPA Survey for Low-Income Adolescents can be used to better understand the relationship between PBPA among low-income teens. Further research is warranted to validate the scale with other adolescent subgroups.

Nodding off but can't disconnect: development and validation of the iNOD index of Nighttime Offline Distress

BACKGROUND

There is a pressing need to update sleep models, education and treatment to better reflect the realities of sleep in a 24/7 connected social world. Progress has been limited to date by available measurement tools, which have largely focused on the frequency or duration of individuals' social media use, without capturing crucial sleep-relevant aspects of this inherently social and interactive experience.

METHODS

Survey data from 3008 adolescents (aged 10-18 years) was used to rigorously develop and validate a new self-report measure that quantifies difficulty disengaging from social media interactions at night: the index of Nighttime Offline Distress (iNOD). Exploratory and Confirmatory Factor analyses in a random split sample produced a ten-item two-factor solution, with subscales capturing concerns about Staying Connected and Following Etiquette (Cronbach's alphas = 0.91 and 0.92 respectively).

RESULTS

Those with higher scores on these subscales tended to report using social media for longer after they felt they should be asleep (r_s = 0.41 and 0.26, respectively), shorter sleep duration (r_s = -0.24 and -0.17, respectively) and poorer sleep quality (r_s = -0.33 and -0.31, respectively). Results also pointed towards a potentially fragmented process of sleep displacement for those who may struggle to disconnect - and to stay disconnected - from social interactions in order to allow sufficient uninterrupted sleep opportunity.

CONCLUSIONS

These findings can inform current models for understanding normal and disordered sleep during adolescence, whilst highlighting specific social concerns as important potential targets for sleep education efforts.

Psychometric Properties of the Environmental Reward Observation Scale: Study on Its Internal Structure, Factor Invariance, and Method Effect Associated With Its Negative Items

The aim of this study was to assess the factorial structure of the scale, the method's effect associated with its negative items, its temporal invariance, and factorial invariance according to sex. For this purpose, three samples were collected, an initial sample of 200 participants, a second sample of 461 participants and a third sample of 107 participants; making a total of 768 Peruvian university students. Other instruments were applied together with the EROS scale in order to measure satisfaction with life, anxiety, stress and depression. Regarding the results, in the initial sample it was found that the original scale containing positive and negative items does adequately fit the data (RMSEA = .19; CFI = .77; TLI = .71) and also evidence was found supporting the existence of a methodological effect associated with the negative items. It was also found that version B of the scale which only has positive items data fits the data (RMSEA = .13; CFI = .96; TLI = .95). In the second sample it was found that version B still had a good fit to the data in a larger sample (RMSEA = .07; CFI = .98; TLI = .98). In addition, it was found that the scale can be considered invariant according to sex and presents validity based on other constructs. In the third sample it was found that the test-retest reliability of the scale was adequate (.70 [CI95% .593-.788]) and also evidence was found in favor of the temporal invariance of the scale. It is concluded that the scale formed only by positive items presents more robust psychometric properties and constitutes a better alternative to measure the level of reward provided by the environment.

Measuring Community Integration: Development and Psychometrics of the Community Connections and Engagement Scale

The objective of this community-based participatory research project was to develop a clinically useful, psychometrically-sound scale to measure community integration for adults with severe mental illness. Two researchers and an administrator of a behavioral health agency (BHA) recruited a group of providers, half with lived-experience of severe mental illness. Through a series of five focus groups, provider participants guided identification of four major domains of community integration and the development of 95 scale items; items and domains were reviewed by three external researchers with subject matter expertise. Initial pilot: BHA providers administered the scale to clients (n = 51) with 19 completing it twice to investigate internal consistency, test-retest reliability, and restricted variance and collinearity of items. Further piloting: providers at two BHAs administered the scale to clients (n = 178) to conduct exploratory factor analysis and analyze internal consistency. After initial pilot, 50 items remained post item reduction for restricted variance and collinearity, with Cronbach's alpha of .95 and test-retest reliability of .90. After a larger pilot, a four-factor solution emerged, aligning conceptually with the four domains as anticipated; 33 items loaded (factor loadings ≥ .4), with RMSEA of .069 and overall Cronbach's alpha of .89 (subdomains ranging .78-.86). The scale has good preliminary psychometric properties and appears to be feasible for use in BHAs for the purposes of research and evaluation, with clinical utility for assessment and treatment planning.

The Impact of Positive Youth Development Attributes and Life Satisfaction on Academic Well-Being: A Longitudinal Mediation Study

While research studies revealed that positive youth development (PYD) attributes have beneficial impact on adolescent developmental outcomes, whether and how PYD qualities are related to academic well-being (such as academic stress and academic satisfaction) are unclear. Based on a longitudinal study (N = 2,312 secondary school students; Mage = 12.54 ± 0.68; 51% female) in Hong Kong, the present study tested a longitudinal mediation model in which it was hypothesized that PYD qualities predicted life satisfaction, academic stress, and academic satisfaction, with satisfaction with life mediating the influence of PYD qualities on academic well-being. Results showed that PYD qualities positively predicted academic satisfaction but negatively predicted academic stress over time. While life satisfaction partially mediated the influence of PYD attributes on academic satisfaction, it fully mediated the influence of PYD attributes on academic stress. The present study supports the proposed conceptual model and underscores the role of PYD qualities in academic well-being through the mediation of life satisfaction.

Factor analysis of signs of childhood apraxia of speech

PURPOSE

To investigate the latent factors underlying signs of childhood apraxia of speech (CAS) in a group of 57 children with CAS.

METHOD

The speech of 57 children with CAS (aged 3;5-17;0) was coded for signs of CAS. All participants showed at least five signs of CAS and were judged to have CAS by speech pathologists experienced in pediatric speech disorders. Participants were selected to represent a range of severity of CAS: 30 children were verbal and 27 were minimally verbal with comorbid autism. Participants' scores for each sign (the number of times that sign appeared during a child's speech sample) were converted to z-scores, then entered as variables into an exploratory factor analysis. Models were compared using the Akaike Information Criterion (AIC).

RESULTS

The three-factor model had the lowest AIC and best fit the data. After oblique rotation, syllable segmentation, slow rate, and stress errors loaded most highly on Factor 1. Groping, addition of phonemes other than schwa, and difficulty with coarticulation loaded most highly on Factor 2. Variable errors loaded most highly on Factor 3. Thus, factors were interpreted as being associated with (1) prosody, (2) coarticulation, and (3) inconsistency.

CONCLUSIONS

Results are consistent with the three consensus criteria for CAS from the American Speech-Language-Hearing Association: Inappropriate prosody, disrupted coarticulatory transitions, and inconsistent errors on repeated tokens. High loading of the syllable segmentation sign on the inappropriate prosody factor also supports the use of a pause-related biomarker for CAS.
