Problematic Technology Use Scale for Young Children (PTUS-YC): Validity and Reliability Study

This study aimed to develop a measurement tool to identify preschool children’s problematic technology use levels and contribute to Turkish literature. The study group included in the exploratory factor analysis was composed of 357 voluntary children in the preschool period. The study group included in the confirmatory factor analysis, proximal validity analysis, item discrimination analysis, and reliability analysis was composed of a total of 402 parents. Exploratory factor analysis (EFA) was conducted to present the factor structure of PTUS-YC. Confirmatory factor analysis (CFA) was performed to test the model obtained with EFA. Item discrimination values obtained as a result of the independent sample t-test was investigated to determine the internal validity of the measurement tool. Furthermore, the correlation values between PTUS-YC items and the relevant factors and the complete measurement tool were calculated, and total item correlation was used to test whether each item served a common purpose. In addition, CR and AVE values were examined in the proximal validity analysis conducted for PTUS-YC. Reliability analysis for PTUS-YC was performed using Cronbach alpha internal consistency coefficient and McDonald's Omega coefficient methods. As a result of the exploratory factor analysis, a 4-factor structure that explained 60.392% of the total variance was obtained: continuity of use, resistance to control, effects on development and deprivation-escape. Based on the results, PTUS-YC was a valid and reliable measurement tool that can be used to determine preschool children's problematic technology use levels.

Psychometric properties of the perceived stress scale (pss-10) with breast cancer patients.

Breast cancer diagnosis is one of the most difficult events that a woman can experience during her life and it usually produces high levels of stress. Global measures of perceived stress are useful for screening and for comparing stress levels between cancer patients and other clinical and nonclinical populations. One such instrument that is widely used is the Perceived Stress Scale (pss-10), but its psychometric properties have scarcely been analysed with breast cancer patients. The aim of this study was to provide validity evidence regarding the use of the 10-item version of the pss-10 as a tool for measuring perceived stress in this context. Participants were 215 Spanish breast cancer patients who completed the PSS-10 and the DASS-21, a measure of affective distress (depression, anxiety, and stress). The internal structure of the PSS-10 was examined through confirmatory factor analysis (CFA), and the reliability of test scores was estimated using McDonald's omega coefficient. Validity evidence based on relationships with other variables was also obtained using correlation analysis. The CFA supported a correlated two-factor structure: perceived helplessness (six negatively worded items) and perceived self-efficacy (four positively worded items). Reliability coefficients for scores on these two factors were 0.87 and 0.73, respectively. Scores on affective distress (DASS-21) were strongly and positively correlated with perceived helplessness and moderately and negatively correlated with perceived self-efficacy. The PSS-10 is an adequate tool for measuring perceived stress in the breast cancer context and it may be useful for identifying women at risk of psychological maladjustment.

Psychometric evaluation of the body understanding measure pregnancy scale Chinese version for pregnant Chinese women

ObjectivesAt present, there is limited research on pregnancy body image and no valid tool to measure body image in pregnant Chinese women. The purpose of this study was to translate the Body Understanding Measure Pregnancy Scale into Chinese to determine its reliability and validity in measuring body image in pregnant women. MethodsThe translation of the Body Understanding Measure Pregnancy Scale (BUMPs) was carried out with a standardized procedure. This study was conducted from July to December 2020 in the outpatient department of three tertiary hospitals in China. There were 1069 pregnant women completed the questionnaire and 1057 of those women were included in the analysis. Internal consistency, test-retest reliability, content validity, and construct validity of the translation version were examined. ResultsThe final Chinese version of the BUMPs (BUMPs-C) had four dimensions with 16 items. Exploratory factor analysis obtained a three-factor solution, which explained 50.26% of the total variances. Confirmatory factor analysis showed that the model fit of the four-factor model was better than the three-factor model, and the four-factor model also reached a satisfactory model fit after modifying: Minimum Discrepancy was 2.82; Comparative Fit Index was 0.939, and Tucker-Lewis Index was 0.92; Root Mean Square Error of Approximation was 0.059. The content validity index of the scale was 1.0; the Cronbach's alpha (α) coefficient was 0.82 for the total scale, the McDonald's omega (ω) coefficient was 0.829; the test-retest reliability was 0.796. ConclusionsThe BUMPs-C showed good reliability and validity among pregnant Chinese women, which can be used as a simple and valid measurement tool to assess the feelings of pregnant Chinese women on body changes during pregnancy.

Psychometric properties of a Chinese version of four-factor colorectal cancer screening belief scale

ObjectiveScreening improves the early diagnosis rate of colorectal cancer (CRC) and effectively reduces its mortality. The four-factor CRC screening belief scale is conducive to understanding the psychometric properties of screening beliefs, but no Chinese version of this scale is available. The purpose of this study was to test the psychometric properties of a Chinese version of the four-factor ​CRC ​screening belief scale in ​patients ​with cancer and their relatives. MethodsThe four-factor CRC screening belief scale was translated into Chinese based on Brislin's model. A panel review ensured the cultural adaptation and content validity of the scale. The scale was then administered to a convenience sample of 425 Chinese people recruited from July 2019 to June 2021. ResultsExploratory factor analysis identified the factor structure for the Chinese version of the four-factor CRC screening belief scale, including perceived barriers, perceived benefits, self-efficacy, and optimism. Confirmatory factor analysis showed that the model fits well. The scale-level content validity index was 1.0. The correlation between the Chinese version of the four-factor CRC screening belief scale and the CRC health belief model scale was statistically significant (r = 0.831, P < 0.01). McDonald's omega coefficients for the entire scale were 0.939 and 0.774–0.948 for the four subscales. The translated scale had test-retest reliability of 0.719 and split-half reliability of 0.646. ConclusionsThe Chinese version of the four-factor CRC screening belief scale showed adequate reliability and validity. The translation and validation of psychosocial assessment tools for CRC screening across languages, cultures, and countries will contribute to further international research collaborations and the improvement of the prospects for the prevention and care of CRC.

Development and Validation of a Rapid Assessment Version of the Assessment Survey of Primary Care in China.

BackgroundMeasuring quality of primary care has attracted much attention around the world. Our team has developed and validated an Assessment Survey of Primary Care (ASPC) for evaluating quality of primary care in China. To facilitate the daily use of ASPC, this study aimed to develop and validate a rapid assessment version of ASPC (RA-ASPC) in China.MethodsThis is a multi-phase study on 21 experts and 1,184 patients from 12 primary care facilities in 10 cities in China. Importance, representativeness, easy understanding, and general applicability of each item in ASPC scale were rated to select the top two ranked items for constituting RA-ASPC. Reliability of RA-ASPC was tested by calculating both Cronbach's alpha and McDonald's omega coefficients. Structural validity was assessed by exploratory and confirmatory factor analysis (EFA and CFA). Concurrent validity was performed by analyzing the relationship between RA-ASPC and patient satisfaction. Discriminant validity was tested by assessing the difference of RA-ASPC scores between patients with or without family doctors.ResultsTen items were selected for RA-ASPC. Both Cronbach's alpha (0.732) and McDonald's omega (0.729) suggested satisfactory internal consistency. In EFA, explained variance of RA-ASPC (72.6%) indicated its ability to measure quality of primary care in China. CFA indicators showed convincing goodness-of-fit (GFI = 0.996, AGFI = 0.992, CFI = 1.000, NFI = 0.980, RMR = 0.022, and the RMSEA = 0.000) for RA-ASPC. Positive association between RA-ASPC and patient satisfaction supported the concurrent validity of RA-ASPC. Patients with family doctors perceived higher quality of primary care than those without family doctors, indicating good discriminant validity of RA-ASPC.ConclusionThe theoretical framework of RA-ASPC was in line with internationally recognized core functions of primary care. Good psychometric properties of RA-ASPC proved its appropriateness in assessing quality of primary care from patients' perspectives in China.

Validation of a Spanish Version of the Health Assessment Questionnaire-II to Assess Mexican Patients' Physical Function with Rheumatoid Arthritis.

To evaluate the validity, reliability, and performance of the Health Assessment Questionnaire-II(HAQ-II) Spanish version questionnaire to measure physical function. A cross-sectional study of 496 patients with rheumatoid arthritis, distributed in 2 samples. The construct validity was evaluated employing the confirmatory factor analysis and the validity based on the relationship with other variables. Cronbach's alpha (α) and McDonald's omega (ω) coefficient were used to determine reliability. Item performance was analysed by fitting different models of item response theory. The one-factor model presented a poor fit in the confirmatory factor analysis; an exploratory factor analysis was carried out, which suggested a 2-factor structure. The confirmatory factor analysis in the second sample confirmed that the second-order model had a good fit to the data. The general factor explained more than 70% of the variance. The reliability indices showed adequate internal consistency (α=.92-.95; ω=.88-.93). Ninety-three percent of the contrasting hypotheses about the relationship of the HAQ-II scores with other variables were confirmed, demonstrating their convergent, divergent, and known group validity. The multidimensional graduated response model was the one that best predicted person's interaction with the items. The Spanish version of the HAQ-II presents adequate validity and reliability for measuring Mexican patients' physical function with rheumatoid arthritis.

French translation and validation of the Karitane Parenting Confidence Scale

IntroductionPerceived parental self-efficacy (PSE) is thought to play a crucial role in parental well-being, the parent-infant relationship, and other aspects of infant development, particularly in the early postnatal period. The Karitane Parenting Confidence Scale (KPCS) is a 15-item self-report questionnaire designed for parents with infants aged 0–12months. ObjectiveTo explore the factor structure of a French translation of the KPCS and assess its psychometric qualities. MethodUsing a French-language translation of the KPCS (KPCS-F), 257 parents of children aged 0–12months were recruited via childcare structures (e.g. nurseries, community centers, mother and child protection centers). Confirmatory factor analyses (CFA) were conducted to examine 2- and 3-factor solutions for the KPCS-F scale. Internal reliability and convergent validity were evaluated. ResultsThe best model was a two-factor solution (PSE “infant care” and PSE “parental role”) restricted to 12 items. Sound internal consistency was indicated, with a Cronbach's alpha coefficient of 0.80 and a McDonald's omega coefficient of 0.80. Test-retest reliability was good. KPCS-F score was correlated with social support and psychological well-being scores. ConclusionThe KPCS-F showed substantial validity and reliability for this sample. The translated scale should therefore improve assessment and intervention processes for professionals working with parents of young children.

Psychometric evaluation of the perceived nursing student's Incivility questionnaire.

AimStudent's uncivil behaviour is one of the most common problems in the educational setting, including nursing schools. It is essential to develop tools for measuring the uncivil behaviour of nursing students to solve this problem. Therefore, this study aimed to evaluate psychometric properties of perceived nursing student's incivility questionnaire among the Iranian community.DesignIn this methodological study, perceived nursing student's incivility questionnaire was completed by 360 nursing students and 121 nursing faculty members.MethodsSampling was done from October 2019–November 2019. Content and construct validity of the questionnaire were evaluated. Reliability was estimated using Cronbach's alpha and McDonald's omega coefficients and composite reliability. The construct validity of nursing student's perceived incivility was investigated by exploratory and confirmatory factor analyses.ResultsContent validity index 0.88 for the whole instrument. The three factors of violent behaviours, irresponsible behaviours and unsound behaviours explained more than 51.485% of the variance. Factor structure extracted using model fit indices (PCFI = 0.763, PNFI = 0.732, CMIN/DF = 2.501, RMSEA = 0.056, GFI = 0.941, AGFI = 0.918, CFI = 0.935) and convergent validity were also confirmed. Internal consistency and composite reliability were estimated to be more than 0.7. The results showed that Iranian perceived nursing student's incivility questionnaire is a three‐dimensional construct with good validity and reliability.

The Hyperphagia Questionnaire: Insights From a Multicentric Validation Study in Individuals With Prader Willi Syndrome.

Background/ObjectivesThe present study aimed to validate the Italian version of the Hyperphagia Questionnaire (HQ), a 11-items questionnaire developed to assess hyperphagia in individuals with Prader-Willi syndrome (PWS). This is a complex neurodevelopmental disorder characterized by endocrine dysfunction, hypotonia, intellectual disability, psychiatric disorders and obesity.MethodsParents of 219 individuals with PWS (age range 3–54 years; Mage = 17.90; 108 Males), recruited in 12 hospitals in Italy responded to HQ during routine visits. In function of the level of analyses the sample was divided into two subgroups (<18> years) or into four age-subgroups (2.5–4.5; 4.5–8; 8–18; >18 years) corresponding to different clinical stages.ResultsConfirmatory factor analysis (CFA) confirmed the three hyperphagic subdimensions of the original structure (behavior, drive, and severity), but one item was dropped out, reducing the final version to 10 items. Using multi-group CFA, HQ showed satisfactory indexes of measurement invariance by age. Good indexes of internal consistency (Cronbach's alpha and McDonald's Omega coefficients) were found for each subdimension. The three hyperphagia subdimensions positively converged with other food-related measures: emotional overeating, food enjoyment, food responsiveness, and satiety responsiveness. A significant increase of all hyperphagic subdimensions was found across age groups. Higher hyperphagic levels were found in participants with higher body mass index. Hyperphagic drive differently increased in function of the interaction between age and underlying genetic mechanisms.ConclusionThe Italian version of the HQ is a psychometrically valid and reliable instrument for assessing hyperphagia in individuals with PWS. This tool may prove useful to evaluate the efficacy of pharmacologic and rehabilitative treatments.

Development and Validation of the Job Satisfaction Brief Scale

This research aimed to develop and validate an instrument to measure job satisfaction in general. A total of 1,491 employed people who worked at least 20 hours per week and were 21 years of age or older participated in the study. The Job Satisfaction Brief Scale was developed with a total of eight items. Several exploratory factor analyses and several confirmatory factor analyses were performed using structural equation modeling to examine the scale's internal structure. The final version of the scale was composed of four items for which Cronbach's alpha and McDonald's omega coefficients were examined and fluctuated between .77 to .78. The results of the factor analyses, especially the confirmatory one, support the one-dimensional internal structure. The new scale appears to be invariance among gender, age, job position, and type of organization. In this way, the results provide evidence of the validity and reliability of the instrument created to measure job satisfaction in general.

Psychometric Validation of the Persian Self-Compassion Scale Youth Version.

ObjectivesEmpirical research investigating self-compassion is a rapidly developing field, and it is potentially crucial in early adolescence. The primary aim of the present study was to psychometrically evaluate the Persian translation of the Self-Compassion Scale Youth version (SCS-Y) and evaluate its factor structure among young adolescents. The second aim was to explore the buffering effect of self-compassion against the negative effect of difficulties in emotion regulation on COVID-19-related anxiety.MethodsA sample of young students (n = 532; mean age 13.57 years) completed an online survey, which included the SCS-Y, Patient Health Questionnaire, Difficulties In Emotion Regulation Scale, Coronavirus Anxiety Scale, Youth Life Orientation Test, Brief Resilience Scale, and Brief 10-Item Big Five Inventory. First-order (six-factor) confirmatory factor analysis (CFA) and bi-factor exploratory structural equation modeling (ESEM) analysis were used to evaluate the factor structure of the SCS-Y.ResultsResults showed that the SCS-Y had very good internal consistency (Cronbach’s alpha coefficient: 0.88; McDonald’s omega coefficient: 0.90), composite reliability (0.87), and adequate test–retest reliability after 4 weeks (0.60). The first-order (six-factor) CFA and bi-factor ESEM analysis demonstrated the SCS-Y had excellent dimensionality. Further analysis found negative associations between self-compassion with both depression and neuroticism, and positive associations between self-compassion with both resilience and optimism. Moreover, self-compassion moderated the association between emotion dysregulation and anxiety generated by the COVID-19. Overall, the findings indicated that the SCS-Y had acceptable criterion-related validity, convergent validity, and discriminant validity.ConclusionsThe findings provide evidence that the SCS-Y is a reliable and valid instrument for assessing the six factors of self-compassion among younger adolescents. Based on the study’s findings, self-compassion appears to be a protective factor against mental health problems during the COVID-19 pandemic for younger adolescents.

60-72 AYLIK ÇOCUKLAR İÇİN DUYGULARI ANLAMA TESTİ’NİN TÜRKİYE UYARLAMASI: GEÇERLİ

The ability to understand emotions, which has been gained since early childhood, is of great importance at the point of gaining emotional competence. We can consolidate emotional competence of children by defining their emotional competence and making regulations in need from early times. In this direction, a valid and reliable measurement tool is needed to measure the ability in understanding emotions of preschool children including Syrian refugee children. The aim of this study is to conduct the validity and reliability study of the Test of Emotion Comprehension (TEC), developed by Pons and Harris (2000), in Turkey. The sample of the study consist of 388 children 263 of whom are Turkish and 125 are Syrian refuge children who are selected from 60-72 months old children studying in kindergartens affiliated to the ministry of national education in Mersin province Akdeniz,Toros,Mezitli and Yenişehir central districts. First, the scale was translated from English to Turkish by three different linguists. Then, it was translated back into English by three other language experts and the consistency between the texts was checked. In addition, the comprehensibility of the items was tested by making a pilot application. The tasks expected from children in the scale were evaluated by pre-school education and measurement field experts. In order to determine the construct validity within the scope of the research, Confirmatory Factor Analysis was performed. As a result of the analyzes, it was determined that the scale exhibited a two-dimensional structure consisting of seven components with 23 items, and it was seen that acceptable fit indices were obtained (χ2/sd=1.84; RMSEA=0.046; CFI= 0.94; TLI=0.90; SRMR=0,10). When factor loading values are examined, ıt was seen that the values for the external dimension are between 0.49 and 0.95; For the Mental and Reflective dimensions, it was found to be between 0.21 and 0.82. In order to obtain information about the reliability of the test, the Mcdonald omega coefficient was examined, 0.81 for the first sub-dimension; 0.56 for the second sub-dimension and 0.81 for the whole scale. These results show that the Test of Emotion Comprehension (TEC) is a valid and reliable tool for assessing children’s ability to understand emotions in Turkey.

Self-reported questionnaire on periodontal condition validated for use in Brazil.

There is a current expectation of instruments for periodontal condition surveillance worldwide. The present study aimed to validate the Oral Health Questions Set B (OHQB) for the Brazilian Portuguese and evaluate its temporal stability. This is a sequential mixed-method investigation. After the forward-backward translation process to the Brazilian Portuguese, the OHQB Brazil (OHQB-Br) was applied to 156 participants (39.5 ± 14.14 years; 51.9% males). In sequence, through a full-mouth six-sites/teeth examination and in accordance with the original instrument, the periodontal diagnosis was obtained (March 2020). In January 2021, the OHB-BR was reapplied (n = 71). Ordinal alpha and McDonald's omega tested the internal consistency of the OHQB-Br. Temporal stability was investigated [Spearman correlation, intraclass correlation coefficient (ICC), and the Bland-Altman]. The concurrent validity was also verified, considering the periodontal clinical diagnosis (Kruskal Wallis). The ordinal alpha (0.69) and McDonald's omega (0.73) coefficients showed an adequate internal consistency of the OHQB-Br. The OHQB-Br temporal stability was high, as demonstrated by the Spearman coefficient (0.80) and ICC (0.79) and by the Bland-Altman plot. A concurrent validity showed a direct relationship between the OHQB-Br and the clinical condition of no periodontitis, mild, moderate, and severe periodontitis (p < 0.05). Because the OHQB-Br shows internal validity, temporal stability, and adequately identifies periodontal health and moderate/severe periodontitis, the instrument might represent an important tool, at the public level or other settings, for periodontal surveillance in Brazil.

Short Form of the Pediatric Symptom Checklist-Youth Self-Report (PSC-17-Y): Spanish Validation Study.

BackgroundThe short form, 17-item version of the Pediatric Symptom Checklist-Youth Self-Report (PSC-17-Y) is a validated measure that assesses psychosocial problems overall (OVR) and in 3 major psychopathological domains (internalizing, externalizing, and attention-deficit/hyperactivity disorder), taking 5-10 min to complete. Prior research has established sound psychometric properties of the PSC-17-Y for English speakers.ObjectiveThis study extends psychometric evidence for the acceptability of the PSC-17-Y in a large sample of Spanish adolescents, providing proof of its reliability and structure, convergent and discriminant validity, and longitudinal and gender invariance.MethodsData were collected on 5430 adolescents, aged 12-18 years, who filled out the PSC-17-Y twice during 2018-2019 (7-month interval). We calculated the Cronbach alpha and the McDonald omega coefficients to test reliability, the Pearson correlation for convergent (distress) and criterion validity (well-being, quality of life, and socioemotional skills), confirmatory factor analysis (CFA) for structure validity, and multigroup and longitudinal measurement invariance analysis for longitudinal and gender stability.ResultsWithin structural analysis for the PSC-17-Y, CFA supported a correlated 3-factor solution, which was also invariant longitudinally and across gender. All 3 subscales showed evidence of reliability, with coefficients near or above .70. Moreover, scores of PSC-17-Y subscales were positively related with convergent measures and negatively related with criterion measures. Normative data for the PSC-17-Y are presented in the form of percentiles (75th and 90th).ConclusionsThis work provides the first evidence of the reliability and validity of the Spanish version of the PSC-17-Y administered over the internet to assess mental health problems among adolescents, maintaining the same domains as the long version.

Validation and Measurement Invariance of the Body Appreciation Scale-2 between Genders in a Malaysian Sample.

The 10-item Body Appreciation Scale-2 (BAS-2) is a measurement for individuals to self-report the extent to which they accept and respect their bodies. Although the BAS-2 has been translated into the Malay language and found to have promising qualities, the psychometric characteristics of the English version of BAS-2 remain unknown in the Malaysian context. The present study thus administered the English version BAS-2 and selfie-editing frequency scale to 797 individuals aged 18 to 56 years old in Malaysia. The dataset that was randomly divided into two halves were submitted to exploratory factor analysis and confirmatory factor analysis respectively. Both of the factor analyses consistently support a one-factor model. The Cronbach’s alpha and McDonald omega coefficients were greater than 0.90, indicating that the BAS-2 has good internal consistency. The incremental validity is also evident. A hierarchical multiple regression showed that the BAS-2 score had a positive relationship with selfie-editing frequency after controlling for age and gender. Moreover, the measurement invariance test supported scalar invariance between genders, and an analysis of covariance did not find significant gender differences. Overall, the findings replicate past findings and regularly support the usability of the BAS-2 in the Malaysian context. The implications of the BAS-2 and future directions are also discussed.

Confirmatory factor analysis of the family APGAR questionnaire

IntroductionIn Colombia, the family APGAR questionnaire is often used to evaluate family function. However, there is no confirmatory factor analysis (CFA) to corroborate the proposed one-dimensional structure in Colombian adolescent students. ObjectiveTo perform CFA on the APGAR family questionnaire in high-school students of Santa Marta, Colombia. MethodA total of 1462 students of tenth and eleventh grade of official and private schools completed the family APGAR questionnaire. Students between 13 and 17 years old (M = 16.0, SD = 0.8) were included, of which 60.3% were female, and 55.3% were tenth grade students. The χ2, RMSEA, CFI, TLI and SMSR were estimated in the CFA. The internal consistency of the dimension was calculated with Cronbach alpha and McDonald omega coefficients. ResultsIn the CFA the indexes were χ2 = 9.11, df = 5, P = 0.105; RMSEA = 0.024 (CI90%, 0.000–0.048), CFI = 0.998, TLI = 0.996, and SMSR = 0.009. Cronbach alpha coefficient was 0.819 and McDonald omega, 0.820. ConclusionsThe one-dimensional structure of the APGAR family scale is confirmed in high-school students of Santa Marta, Colombia. This questionnaire is reliable and valid for the measurement of family function in school-aged adolescents.

Translation and validation of the Arabic version of the barrier to access to care evaluation (BACE) scale

Purpose This paper aims to translate and validate an Arabic version of the Barriers to Access to Care Evaluation (BACE) BACE scale to make it appropriate for the targeted socio-cultural and linguistic context. Design/methodology/approach This psychometric study has two main compounds: translating the BACE into Arabic and validating it. Using the back-translation method, the authors involved seven professional individuals to maximize the efficacy of the translated version. The authors began with the process of translating the scale from English into Arabic and vice versa followed by evaluation, compression and matching. Later, a pilot study with a sample size of 35 participants was conducted to receive feedback on the Arabic version of the scale. Finally, an online survey was generated and distributed among Arabic-speaking countries; a total of 630 participants were voluntarily involved in this study. Findings A total of 630 participants completed the survey with a mean age of 31.4 ± 12.9, and 402 (63.8%) were females. Cronbach’s alpha coefficient and McDonald's Omega coefficient were both greater than 0.9. The confirmatory factor analysis was found to fit highly satisfactory with the stigma-related barriers. Research limitations/implications The BACE was validated in Arabic and its psychometric properties were examined in-depth and found to be strong. Originality/value This paper fulfils an identified need to translate tools to make mental health more accessible to patients in need.

Psychometric Properties of the Nine-Item Problematic Internet Use Questionnaire in a Brazilian General Population Sample.

Objective: The goal of the study is to adapt and examine the psychometric properties of the Brazilian version of the nine-item Problematic Internet Use Questionnaire (PIUQ-SF-9).Methods: A convenience sample of Brazilian internet users aged between 18 and 89 years (72.7% female, mean age 38.7 years ± 13.5) was recruited online from September 2018 to July 2019 (test sample = 1,525; retest sample = 237). Participants responded to the adapted version of the PIUQ-SF-9, as well as the Center for Epidemiologic Studies-Depression Scale (CES-D-10) and sociodemographic questions.Results: A bifactor model with one general factor and three specific dimensions (obsession, neglect and control disorder) yielded the best fit indices [χ2 = 67.66, df = 15, CFI = 0.99, TLI = 0.99, RMSEA = 0.048 (0.037–0.060), RMSEA p close = 0.587 and SRMR = 0.01]. McDonald's hierarchical omega coefficient was 0.76 for the general factor and varied between 0.16 and 0.33 for the specific dimensions. The intraclass correlation coefficient was 0.73 for the general factor and varied between 0.64 and 0.72 for the specific dimensions. The MIMIC model supported the scale's construct validity as the relationship of the predictors (age, time spent online, self-perception of problematic internet use, and depression symptoms) with the PIUQ-SF-9 factors was in line with the assumptions based on the literature.Conclusion: PIUQ-SF-9 seems to be a brief and culturally validated instrument with sound psychometric properties to be used in future studies on problematic internet use in the Brazilian population.

The development of a shortened, Korean version of the Anticipated Turnover Scale for hospital nurses.

This study was a psychometric validation of a Korean version of the Anticipated Turnover Scale (ATS) involving translation, transcultural adaptation, and validation. We used data from a cross-sectional online survey of 287 Korean practicing nurses in hospitals. Confirmatory factor analysis (CFA) assessed the validity of the one-factor structure that was hypothesized in the original version. We removed any items that did not enhance the scale's reliability and validity. Test and retest reliability was performed on 206 of the nurses who completed the survey again two weeks later. The mean age of the 287 nurses was 33 years, and 278 (97%) of them were female. The final 6-item Korean version of the ATS demonstrated a satisfactory model fit in the CFA (χ2 = 22.67; degree of freedom = 9; goodness-of-fit index= 0.97; comparative fit index = 0.98; Tucker-Lewis Index = 0.97; root mean square error of approximation = 0.07; and standard root mean residual = 0.03). The intraclass correlation coefficient with the test-retest reliability for the 2-week interval was 0.81, with a good internal consistency (Cronbach's alpha = 0.85; McDonald's omega coefficient reliability = 0.92). The 6-item revised ATS is a reliable and valid scale to assess the turnover intention of Korean nurses who work in hospitals. It can be used in an acute setting and predict the anticipated turnover rate for monitoring purposes.

Adaptation of the SenSel creativity-sensitization and self questionnaire for educators and teachers into Turkish and its relationship with mathematical thinking skills

The aim of this study is to measure whether there is a relationship between classroom teachers' sensitivity to creativity phenomenon and their level of mathematical thinking. While the universe of the research is the classroom teachers working in city located in the Southeastern Anatolia part of Turkey, the sample is 509 classroom teachers who work in various schools in the center of city. In the study, firstly, the SenSel Creativity-Sensitization and Self Questionnaire for Educators and Teachers was adapted to Turkish and then the mathematical thinking levels of the teachers were measured with the "Mathematical Thinking Scale". Confirmatory factor analysis was performed with the Lisrel program to test the model fit of the item-factor structure of the test during the adaptation phase, and the Cronbach's Alpha coefficient and McDonald's Omega Coefficient were calculated for reliability analyses. In the second stage of the study, the correlation of the Educators' Sensitivity to Creativity Test and the Mathematical Thinking Scale were investigated. At this stage, normality test (Kolmogrov Smirnov), descriptive statistics, Pearson product moment correlation analysis, regression analysis, T-test and single factor ANOVA operations were done with SPSS 23 program. Considering the results of the research, the Test of the Educators' Sensitivity to Creativity was adapted to Turkish; while CFA results suggested adequate model fit, the Cronbach Alpha coefficient was .96, McDonald's Omega coefficient was determined as .97 and the test was determined to be highly reliable. In the second stage, a positive significant relationship was found between the classroom teachers’ sensitivity to creativity and their level of mathematical thinking, and it was determined that the level of sensitivity to creativity phenomenon explained 22 % of classroom teachers' mathematical thinking levels. Some suggestions were made according to the results of the study.
