Validation of the Thai translation of the attitudes toward euthanasia scale

This study aimed to examine the psychometric properties of the Non-Attachment Scale Short Form in a Turkish sample. With the participation of 244 adults over 18 years of age, the Short Form of the Nonattachment Scale, the Resilience Scale and the Ontological Addiction Scale were used as data collection tools. Cronbach's alpha and McDonald's omega coefficient were used for the reliability of the Non-Attachment Scale Short Form. According to the results of the analyses, the internal consistency coefficient and McDonald's value were found to be .77 and .78, respectively. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were used to test the construct validity of the scale. The results of the analyses showed that the model fit and Kaiser-Meyer-Olkin (KMO) values were at an acceptable level. Item factor loadings ranged between .40 and .67 and the scale was found to have a single factor structure. The statistically significant difference between the 27% lower and upper groups among the participants showed that the item discrimination index of the scale was at a good level. According to the correlation findings conducted to test the criterion validity of the scale, non-attachment was found to have positive significant relationships with resilience (r = .60) and negative significant relationships with ontological dependence (r = -.39). As a result, adaptation of the Short Form of the Non-Attachment Scale can be said to be a valid and reliable measurement tool.

BackgroundReasonable instruction and promotion of appropriate exercise are crucial to improving the exercise status of pregnant women and safeguarding the health of both mother and fetus. However, there is a lack of validated Pregnancy Exercise Attitude Scales with a complete evaluation system in China. This study aims to assess the validity and reliability of the Pregnancy Exercise Attitude Scale (C-PEAS) in Chinese to give medical professionals a reference for carrying out pregnancy care services and promoting the health of the mother and fetus.MethodsIn this study, the scale was translated, back-translated, and cross-culturally adapted using the Brislin translation model to form the C-PEAS. 528 pregnant women were conveniently selected for the questionnaire survey to evaluate the scale's reliability. The scale's content validity was assessed by the content validity index, while its structural validity was investigated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Cronbach's alpha coefficient, McDonald's omega coefficient, split-half reliability, and retest reliability were used to evaluate the scale's internal consistency.ResultsThe C-PEAS contains two dimensions with 37 entries. The EFA supports a two-factor structure with a cumulative variance contribution of 62.927%. The CFA model was well fitted (χ2/df = 1.597, RMSEA = 0.048, IFI = 0.955, TLI = 0.952, and CFI = 0.955). The C- PEAS' Cronbach's alpha coefficient was 0.973, and the range of Cronbach's alpha values for the dimensions was 0.976, 0.944. McDonald's omega coefficient was 0.971, the half-point reliability of the scale was 0.856, and the retest reliability was 0.966.ConclusionsThe Chinese version of C-PEAS has good psychometric properties. It can be used as an effective measurement tool to evaluate the attitude of pregnant women to exercise during pregnancy.

<p style="text-align: justify;"><strong>Objective. </strong>Adaptation of the Parental Stress Scale by J. Berry and V. Jones on a sample of mothers of Russian schoolchildren – first and fourth grade students of elementary schools in Nizhny Novgorod and the Nizhny Novgorod region. <br><strong>Background. </strong>Modern parenting research highlights the complex nature of parenting experiences, the diversity of parental practices, the changes associated with the child's upbringing and the dynamics of the family system, and the combination of both positive and negative emotions in parenting. However, there is a noticeable shortage of tools in the Russian-language literature to measure both parental satisfaction and parental stress. <br><strong>Study design. </strong>The study was conducted using an online survey within the “Longitudinal study of factors of school failure”, implemented in Nizhny Novgorod and the Nizhny Novgorod region. <strong>Participants. </strong>The study included a sample of 900 mothers of fourth grade and 1120 mothers of the first grade school students. <strong>Measurements.</strong> Exploratory and confirmatory factor analysis and McDonald's Omega coefficients were used for psychometric data analysis. The PERMA Profiler questionnaire and correlation analysis were used to assess validity based on convergent and discriminant evidence. The data was analyzed in the Jamovi 2022 and R programs. <br><strong>Results. </strong>Factor analyses of the internal structure suggest two factors, including 8 items each. The subscales “Parental stress” and “Parental satisfaction” demonstrate a high level of internal consistency. The assessment of validity based on the convergent and discriminant evidence confirms the reliability and validity of the instrument. <br><strong>Conclusions. </strong>The scale demonstrates good psychometric properties and can be used for parenting research, as well as in applied projects to improve parental competence and emotional support for parents.</p>

In recent years, research on physical literacy has experienced remarkable growth, identifying the factors in this multidimensional concept that may play a role in the acquisition of healthy habits. In addition, multiple studies have identified significant correlations between physical literacy and quality of life, although they did not find a reason for this relationship. One of the factors that could explain this behavior is physical fitness. Therefore, this study aimed to analyze the role of physical fitness and its components in the relationship between physical literacy and life satisfaction. For this purpose, the Mann-Whitney U test was used to analyze the differences in the scores of the questionnaires applied, Spearman's rho, to determine the correlations between physical literacy and life satisfaction, using Hedges' g for the interpretation of the effect size. In addition, a mediation analysis was conducted to understand how physical fitness affects the relationship between literacy and life satisfaction. A moderation analysis was then applied to explore whether variables related to physical fitness modified the correlation and added to the prediction model. Finally, the reliability and validity of the questionnaires were tested using Cronbach's Alpha and McDonald's omega coefficient. The results showed that physical fitness, especially cardiorespiratory fitness, was a moderator and mediator in this relationship, demonstrating that increasing cardiorespiratory fitness enhances the effect of physical literacy on improving life satisfaction among high school students.

The present study aimed to contribute to analyzing the psychometric properties of the WHO Quality of Life Scale for Older Adults (WHO-QoL-Old) in a sample of older adults in Michoacán, Mexico. 111 older adults from Michoacán, Mexico, participated in the study. Confirmatory factor analysis (CFA) was conducted to test the fit of various models. Data analysis was performed using R Studio, considering the ordinal nature of the items in the model estimation method. Internal consistency was evaluated using the alpha coefficient (α) and McDonald's omega coefficient (ω). The CFA indicated that the six-correlated-factor model proposed theoretically showed a very good fit (χ2: 397.11, p < 0.001; CFI: 0.958; SRMR: 0.079; RMSEA: 0.079). The factors within the model demonstrated acceptable internal consistency, with an alpha coefficient ranging from 0.739 to 0.874 and an omega coefficient ranging from 0.748 to 0.882. It is concluded that the WHO-QoL-Old scale presents good psychometric properties for the Mexican older adult population.

BackgroundMost medical organizations accept many nursing students each year who gain clinical practice skills under the supervision of clinical nurses. However, there are no assessment tools to measure the contributions nursing students make to the clinical setting during clinical practicum. This study aimed to translate the 'Nursing Student Contributions to Clinical Settings' scale into Chinese and test its reliability and validity from the perspective of Chinese clinical nurses. And to explore whether nurses' personal and professional characteristics are related to nurses' perception of nursing students' contributions to the clinical settings.MethodsThe original scale was translated into Chinese following the Brislin translation model. A convenience sample of 935 clinical nurses was selected from January to March 2024 for the survey. The content validity of the scale was assessed by expert consultation and content validity index. Exploratory factor analysis and confirmatory factor analysis were performed to assess the construct validity of the scale. The reliability of the scale was measured using internal consistency, split-half reliability, and test–retest reliability. The measurement quality of the scales was assessed according to the COnsensus-based Standards for the selection of health Measurement INstruments. One-way analysis of variance was used to identify variables related to students’ contributions.ResultsThe content validity index of the scale was 0.983. Exploratory factor analysis supported a one-factor structure, and the cumulative variance contribution was 71.177%. Confirmatory factor analysis showed that the model fit indicators were all within the acceptable range. The McDonald's Omega coefficient and Cronbach's alpha coefficient for the scale were 0.983. Nurses perceive that nursing students' contribution to the clinical settings is influenced by nurses' personal characteristics, professional characteristics, and the hospital environment.ConclusionThe Chinese version of the Nursing Student Contributions to Clinical Settings scale has good reliability and validity and can effectively and reliably measure the contributions of Chinese nursing students to clinical settings.

&lt;p&gt;The development of imaginative thinking is one of the main tasks of educational work with preschoolers, because it allows the child to be successful in preschool activities, where the most favorable conditions for the formation of age new achievements are formed. The need for diagnostic tests to determine the level of imaginative thinking of preschoolers is related both to the need to assess the effectiveness of educational work with children, and to identify the level of development of the child. The most informative and reliable results of the assessment of cognitive processes are provided by the use of standardized test. In Russian psychology, there is only one such test - "Schematization" (author R.I. Bardin). This test was created and standardized at the end of the last century and its psychometric characteristics and assessment standards need to be updated for a modern sample. The article presents the results of the re-standarization of this test. The experimental sample of the study consisted of N = 2425 children of senior preschool age: children 5-6 years old (M = 66 months; SD = 3.09 months; n = 974) and 6-7 years old (M = 77 months; SD = 3.21 months; n = 1451). For psychometric verification, confirmatory factor analysis, Cronbach's alpha and McDonald's omega coefficients, Spearman correlation coefficient, Mann-Whitney U criterion and two-factor analysis of variance were used. The norms were calculated using percentile normalization. The obtained results showed the conformity of the test with psychometric requirements and allowed us to determine the current norms for the development of imaginative thinking of older preschool children.&lt;/p&gt;

This study aims to develop and validate the Online Risk-Taking Scale. Based on the results of expert opinions and a trial application, a 20-item draft form was created. This scale includes 20 questions about behaviors that are considered risky and have been performed in the last six months. The scale was administered to 214 secondary school students as an online questionnaire, and data were collected. Validity and reliability studies were conducted using these final data. Exploratory factor analysis and confirmatory factor analysis were performed to determine the validity levels of the scale. Cronbach's α coefficient and McDonald's Omega (ω) coefficient were analyzed to assess the reliability levels. The scale demonstrated satisfactory validity and reliability. As a result, a valid and reliable measurement tool that will contribute to the literature by determining the online risk-taking levels of secondary school students has been obtained.

BackgroundInnovation in nursing involves applying new knowledge to create novel ideas, methods, or technologies, resulting in higher-quality care and improved patient outcomes. Adequate support for innovation is crucial for progress in nursing. This study aimed to translate the Innovation Support Inventory (ISI-12) into Persian and assess its psychometric properties specifically among clinical nurses.MethodsA methodological cross-sectional study was conducted from September 2022 to July 2023 to evaluate the face, content, and construct validity of the ISI-12. Construct validity was assessed through confirmatory factor analysis (CFA) and convergent and discriminant validity evaluation using data obtained from 321 clinical nurses. The test–retest stability and internal consistency of the ISI-12 were also evaluated to assess its reliability.ResultsThe Persian version of the ISI-12 validation through confirmatory factor analysis has confirmed its fit with the proposed three-factor model. The ISI-12 demonstrated high reliability, as evidenced by a Cronbach's alpha coefficient (α = 0.969), McDonald's omega coefficient (ω = 0.922), coefficient H (H = 0.979), and mean inter-item correlation (ρ = 0.418). Additionally, the stability of the ISI-12 during two weeks among 40 clinical nurses was found to be excellent, with an ICC of 0.951.ConclusionThe Persian version of the ISI-12 is a valid inventory for evaluating the innovation Support of clinical nurses.

Problematic use of the Internet among adolescents has risen in the last decade. The Compulsive Internet Use Scale (CIUS) is one of the most frequently internationally-used tools developed to assess Problematic Internet Use (PIU). However, evidence concerning its validity and reliability in its Spanish version for the adolescent population is currently lacking. Thus, the main goal of the present study was to analyse the psychometric properties of CIUS scores in a large sample of Spanish adolescents. The sample consisted of 1,790 participants (53.7% female, mean age = 15.70 years old, SD = 1.26). The one-dimensional model displayed appropriate goodness of fit indices after error covariance of five items were allowed to correlate. Strong measurement invariance was found for the one-dimensional model across age and gender. The McDonald's Omega coefficient for the total score was 0.91. Furthermore, PIU was positively associated with different indicators of poor wellbeing and psychological difficulties and negatively associated with prosocial behaviour, self-esteem and sense of belonging to the educational centre. The study provided evidence of validity for the CIUS, confirming its utility for screening PIU in non-clinical adolescents.

The purpose of the present study was to develop and conduct a preliminary psychometric evaluation of the Self Disclosure to Romantic Partner Scale that assesses adults' attitudes towards sharing their personal information that includes disturbing feelings, thoughts, and experiences with their romantic partners. Two studies were conducted for this purpose. The first study was carried out with 200 participants and the second study was conducted with 206 participants. Exploratory factor analysis and confirmatory factor analysis showed a one-dimensional factor structure for the seven items of the Self Disclosure to Romantic Partner Scale. Furthermore, the results indicated that Cronbach alpha and McDonald's omega coefficient of Self Disclosure to Romantic Partner Scale were over .70 for both studies. Taken together, these findings suggest that Self Disclosure to Romantic Partner Scale has good psychometric properties.

The Phubbing Scale (PS) is an instrument used to measure the frequency and extent of the behavior of ignoring someone you are with and giving attention to your mobile phone instead. However, there is insufficient evidence about the psychometric adequacy of the Spanish version of the instrument. The main goal of this research was to analyze the psychometric properties of PS in a representative sample of Spanish adolescents and young adults. A total of 1351 participants comprised the sample (42.78% females, age range = 12-21). Students were selected from different levels of education such as secondary school, high school, vocational training, or university. A convenient sample was used. The reliability of the scores was calculated by means of McDonald's Omega. The evidence of the internal structure of the questionnaire was analyzed by means of confirmatory factor analysis (CFA). The measurement invariance of the instrument by gender and educational level was also calculated. In addition, Pearson's correlations between phubbing and other indicators of mental health were also calculated. The goodness-of-fit indices for the two-factor model were good. The McDonald's Omega coefficient for the total score was 0.787. Measurement invariance both by gender and educational level was found. The phenomenon of phubbing was found to have statistically significant correlations with emotional well-being, other mental health indicators, and with Problematic Internet Use (PIU), with the sole exception of the hyperactivity subscale of the SDQ. This study provided validity evidence for the Spanish version of the Phubbing Scale (PS), suggesting that PS is a reliable tool for quantifying phubbing in Spanish adolescents.

To design and validate a Brazilian version of the Animal Empathy Scale, based on the existing Portuguese version. Content validity assessment was performed by expert judges, and the adapted scale was administered to a sample of 386 participants. Exploratory and confirmatory factor analyses were performed. The bifactorial profile of the scale remained consistent, comprising Empathic Concern for Animals (Cronbach's alpha and McDonald's omega coefficients: 0.75) and Emotional Attachment with Animals (Cronbach's alpha and McDonald's omega coefficients: 0.79). Considering the One Health framework, collaborative, multidisciplinary, and intersectoral approaches are essential for achieving optimal health conditions for people, animals, and the environment given their intricate interconnections. Empathy plays a crucial role in promoting proximity between humans and animals, fostering positive connections that encourage biodiversity conservation. The 13 statements were retained, confirming the validity of the animal empathy scale for use in Brazil, and a Brazilian version of the Animal Empathy Scale was established.

Psychometric evaluation of the Indonesian version of paternal breastfeeding self-efficacy scale- short form: A confirmatory factor analysis

The prevalence of depression in the community is high. Therefore, it is necessary to examine the information needs on depression in the community. This cross-sectional study aimed to translate and evaluate the psychometric properties of the Depression Information Needs Scale (DINS) among the general population. The translation and assessment of the validity and reliability of the DINS were conducted from February 2022 to May 2023 in Gonabad, Iran. The inclusion criteria in this study were individuals 18 years or older, those living in Gonabad for 1 year or more, and participants who provided written informed consent. Sample sizes of 546 and 629 were used for the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), respectively. The reliability of the DINS was examined using three methods: McDonald's omega coefficient, test-retest reliability, and Cronbach's alpha coefficient. Most participants were women, had a bachelor's degree, and were married. The values of 0.959 for scale content validity index averaging (S-CVI/Ave) and 0.817 for content validity ratio (CVR) were calculated. In the EFA section, four factors with eigenvalues greater than 1 were extracted and explained 63.861% of the variance. Only two items were not placed in related or acceptable factors and were deleted. Finally, based on the results of the goodness-of-fit indexes (e.g., RMSEA = 0.074, CFI = 0.944, NFI = 0.930, and GFI = 0.911), the scale was approved with 18 items and 4 factors: lived experience (4 items), general (facts about depression) (6 items), research and policies (4 items), and specific treatments (4 items). For all the DINS items, the McDonald's omega coefficient, Cronbach's alpha coefficient, and Intraclass Correlation Coefficient (ICC) were 0.953, 0.950, and 0.957, respectively. The Persian version of the DINS was validated with 18 items and 4 factors, and this scale can be used to assess depression information needs in the general public and specific groups.

The aim was to examine the psychometric properties of the Hospital Anxiety and Depression Scale (HADS) in cohorts of working age stroke survivors, before and after inpatient rehabilitation. Stroke patients aged 18-66 years registered in the national quality register WebRehab Sweden were included in the study at hospital admission (n = 256), discharge (n = 223), and 1-year follow-up (n = 313). Classical and modern (Rasch) methods were used for psychometric evaluation. The two-factor HADS model measuring anxiety and depression showed better fit than a single factor measuring emotional distress. The instrument's psychometric stability before and after rehabilitation was satisfactory. The anxiety scale showed good psychometric properties, except for item 7, which is not anxiety-specific. Some concerns were observed for the depression items showing weaker discriminant validity, and item 8 performing poorly as a measure of depression. Cronbach's alpha and McDonald's omega coefficients showed satisfactory internal consistency reliability, whereas Rasch person reliability coefficients indicated weaker reliability, especially for the depression scale. Effect size of change between hospital admission and discharge showed a reduction in anxiety and depression symptoms. HADS showed a stable two-factor structure over the rehabilitation period. Patients' perception of items was not affected by the recovery, allowing relevant comparison of HADS scores between different phases of the rehabilitation process. Measures of responsiveness suggest that HADS is sensitive to capturing improvements in emotional distress following rehabilitation interventions. Overall, despite minor psychometric weaknesses, HADS is a suitable instrument for assessing anxiety and depresssion symptoms in stroke patients aged 18-66 years.

STEM education for deaf students aims to engage and include intellectual and experiential learning other than normal classrooms. These programs improve students' critical thinking, problem-solving, creativity, and complex decision-making, which are essential for academic and life success. This study aims to explore several aspects of a STEM based workshop including problem solving skills, STEM skills, subject knowledge, and effectiveness of the workshop for a group of 27 deaf students. The workshop spanned five consecutive days and focused on problem-solving principles within the context of global warming. Moreover, in this study, the Creative Problem-solving approach developed by Osborn and Parnes was implemented to measure improvement of the constructs above, through a post questionnaire. Cronbach's alpha and McDonald's Omega coefficient exceeded .7 for each construct. The data obtained from the questionnaire demonstrated a random distribution of data according to the Shapiro-Wilk test performed (p < 0.05), leading to the use of non-parametric analysis tools. The results based on the non-parametric test analysis (Kruskal Wallis test) show that high school students' problem-solving abilities improved despite the data's randomness (Mean rank = 16.72). The workshop was enhanced for the Preparatory students, who tended to gain more STEM skills and problem-solving abilities from it (Mean rank = 14.75). It also improved the knowledge and STEM skills of Primary-stage students (Mean rank = 18.13 and 18.06, respectively). This study contributes to the existing body of literature by examining how addressing challenges of global warming can enhance various abilities among deaf students.

The concept of positive occupations that enhance physical, mental, and social well-being is a novel idea that integrates positive psychology and occupational therapy. Valid and reliable scales are required to assess positive occupations for well-being in mental health settings. In this regard, the Assessment of Positive Occupation-15 (APO-15) is unique, as it evaluates positive occupations that promote health and well-being. This study aimed to investigate the validity and reliability of and determine the cutoff value of the Turkish version of the APO-15 in individuals with serious mental illness (SMI). The study was conducted with 106 individuals with SMI. The structural validity of the scale items was determined using confirmatory factor analysis, while the reliability of the scale was analyzed with Cronbach's alpha (α) and McDonald's omega (ω) coefficients. The comparative fit index (0.964) and the Tucker-Lewis index (0.955) demonstrated a good fit. Cronbach's alpha coefficients were .826, .814, .707, and .674, and the total scale score was 0.924. McDonald's ω coefficients for the four scale dimensions were 0.832, 0.818, 0.716, and 0.727. The cutoff point of 49.50 for the APO-15 for point sensitivity (0.727) and specificity (0.766) yielded good results. The Turkish version of the APO-15 is an effective and reliable tool for assessing well-being in mental health settings.
