Недисциплинированность среди учащихся старших классов средней школы: роль домашнего контроля поведения и религиозности

<p>The study investigated the indiscipline of senior secondary school students and the contribution of home behaviour control and religiosity in Cross River State, Nigeria. An ex-post facto research design was adopted for the study. The population comprised 62,501 senior secondary school students in three educational zones. A multistage sampling procedure was adopted to select 1250 students from 30 randomly sampled public and private secondary schools. The Student Opinion Questionnaire (SOQ) was used for data collection. Experts in measurement and evaluation and educational psychology validated the instrument. The test-retest reliability coefficient ranged from 0.78-0.91. The data collected were analysed using one-way analysis of variance (ANOVA). The results revealed that home behaviour control and home religiosity significantly influenced secondary school students' indiscipline behaviour. Specifically, students from firm homes and with high levels of religiosity generally exhibited lower indiscipline behaviour across all the dimensions. In comparison, those from lax homes and homes with low levels of religiosity manifested higher levels of indiscipline behaviour. These findings align with role theory, which suggests that individuals' behaviour is shaped by their immediate social environment. Policymakers can use these results to develop programs that promote positive behaviour by encouraging the development of a strong religious foundation in the home and promoting clear expectations and rules for behaviour.</p>

Measuring Peer Collaboration Among Secondary School Students: Instrument Development And Validation

This study aims to create and validate a scale that measures peer collaboration among secondary school students. The study had three objectives: 1) to identify the constructs of collaboration, 2) to develop a collaboration scale, and 3) to validate the collaboration scale. The study included 363 9th-grade students, and after an extensive literature review, it identified four constructs of collaboration: social interdependence, conflict resolution, cooperation, and sharing of resources. The consistency between these constructs was found to be positive. The scale reliability was established with a Cronbach’s alpha coefficient of 0.768 and a test-retest reliability coefficient of 0.71. The content validity of the scale was also established with a Cohen kappa coefficient of 0.66. The study found that differences between boys and girls can be determined by obtaining standard scores on the collaboration scale. This new collaboration scale will be a useful tool for practitioners who use constructivist pedagogy to measure collaboration.

Development and validation of the osteoporosis scale among the system of quality of life instruments for chronic diseases QLICD-OS (V2.0)

BackgroundQuality of life of osteoporosis patients had caused widespread concern, due to high incidence and difficulty to cure. Scale specifics for osteoporosis and suitable for Chinese cultural background lacked. This study aimed to develop an osteoporosis scale in Quality of Life Instruments for Chronic Diseases system, namely QLICD-OS (V2.0).MethodsProcedural decision-making approach of nominal group, focus group and modular approach were adopted. Our scale was developed based on experience of establishing scales at home and abroad. In this study, Quality of life measurements were performed on 127 osteoporosis patients before and after treatment to evaluate the psychometric properties. Validity was evaluated by qualitative analysis, item-domain correlation analysis, multi-scaling analysis and factor analysis; the SF-36 scale was used as criterion to carry out correlation analysis for criterion-related validity. The reliability was evaluated by the internal consistency coefficients Cronbach’s α, test-retest reliability Pearson correlation r. Paired t-tests were performed on data of ​​the scale before and after treatment, with Standardized Response Mean (SRM) being calculated to evaluate the responsiveness.ResultsThe QLICD-OS, composed of a general module (28 items) and an osteoporosis-specific module (14 items), had good content validity. Correlation analysis and factor analysis confirmed the construct, with the item having a strong correlation (most > 0.40) with its own domains/principle components, and a weak correlation (< 0.40) with other domains/principle components. Correlation coefficient between the similar domains of QLICD-OS and SF-36 showed reasonable criterion-related validity, with all coefficients r being greater than 0.40 exception of physical function of SF-36 and physical domain of QLICD-OS (0.24). Internal consistency reliability of QLICD-OS in all domains was greater than 0.7 except the specific module. The test–retest reliability coefficients (Pearson r) in all domains and overall score are higher than 0.80. Score changes after treatment were statistically significant, with SRM ranging from 0.35 to 0.79, indicating that QLICD-OS could be rated as medium responsiveness.ConclusionAs the first osteoporosis-specific quality of life scale developed by the modular approach in China, the QLICD-OS showed good reliability, validity and medium responsiveness, and could be used to measure quality of life in osteoporosis patients.

A Practical Tool for Measuring Home-Based Cardiac Rehabilitation Self-Management Behavior: A Multiphase Cross-Sectional Study.

Optimal self-management is the key to home-based cardiac rehabilitation for patients with heart disease. At present, there is a lack of a specific assessment tool to evaluate the home-based cardiac rehabilitation self-management behavior in patients with heart disease. Therefore, the aim of this study was to develop the Home-Based Cardiac Rehabilitation Self-Management Scale and validate its psychometric properties among patients with coronary heart disease. A multiphase cross-sectional study was conducted that study covered 3 phases: (1) item generation and revision, (2) item evaluation and preliminary exploration, and (3) assessment of the psychometric properties of the scale. A scale with 21 items was developed to measure the home-based cardiac rehabilitation self-management behavior. The content validity index of the scale was 0.980. In exploratory factor analysis, the 5-factor structure supported by eigenvalues and screen plot explained 74.326% of the total variation. In confirmatory factor analysis, all fitting indicators were acceptable, further supporting the construct validity of the scale. The criterion validity of the scale was 0.783. In the reliability analysis, the Cronbach's α coefficient of the scale was 0.882, with a dimensionality range of 0.780 to 0.936. The split-half reliability coefficient and test-retest reliability coefficient were 0.774 and 0.770, respectively. This study is the first to develop and validate a practical tool. This scale can comprehensively and accurately assess the self-management behavior of patients with heart disease in a home-based cardiac rehabilitation environment.

Validity and reliability of the Turkish version of the patient on hemodialysis resilience scale.

The study aims to evaluate the validity and reliability of the hemodialysis resilience scale (PHRS) in the Turkish population. A cross-sectional methodologic study involved 136 hemodialysis patients at two dialysis centers affiliated with a foundation university in Turkey. The updated guidelines for the Intercultural Scale Adaptation Stages, Language, and Culture Adaptation were followed. Cronbach's α of the PHRS-Tr was 0.94. A three-factor structure was extracted, namely "the pursuit of positive meaning in the present," "building the will to live through close human relationships," and "acceptance of hemodialysis as a part of daily life" explaining 66.82% of the total variance. Test-retest reliability was conducted with 50 patients within the sample 2 weeks after the first application. The correlation coefficient for test-retest reliability was r = 0.680. The study results indicate that the PHRS-Tr is a valid and reliable tool for assessing resilience status in Turkish hemodialysis patients.

Psychometric properties of the spatial skills self-efficacy scale: A validity and reliability study

The aim of this study was to develop a valid and reliable spatial skills self-efficacy scale for middle school students. To this end, the study sampled 5th-, 6th-, 7th-, and 8-grade students in the spring term of the 2021–2022 academic year. The data were collected from 1369 students for the pilot study and the validity and reliability analysis to investigate the psychometric properties of the scale. Twenty-five subject matter experts were asked for opinions and Lawshe's content validity ratio (1975) was used to measure the content validity of the scale. The results of the exploratory factor analysis conducted for the construct validity yielded a four-factor structure consisting of seventeen items, which accounted for 41.37 % of the total variance. The factor loadings of the scale items ranged from 0.41 to 0.75. When the fit indices of the model were examined as a result of Confirmatory Factor Analysis, it was determined that the firstorder multifactor structure were within the excellent or acceptable value ranges. The Cronbach's alpha coefficient was found to be 0.77 for the total scale. The results of the independent samples t-test for the upper and lower 27 % groups showed a significant difference between the groups for all scale items. The correlation coefficients of the subscales with one another and with the total scale showed significant positive moderate and high correlations. The test–retest reliability coefficients also showed significant positive moderate and high correlations. These results indicate that the Spatial Skills Self-Efficacy Scale is a measurement tool that produces valid and reliable measurements and can be used to determine the spatial skills self-efficacy of middle school students.

Development and Validation of the Coronary Heart Disease Scale Among the System of Quality of Life Instruments for Chronic Diseases QLICD-CHD (V2.0) Based on Classical Test Theory and Generalizability Theory.

Coronary heart disease (CHD) is a common and frequent disease with a long and incurable course, and the quality of life of patients is severely reduced. This study was to develop and validate a quality of life scale for patients with CHD based on the Chinese context. The scale QLICD-CHD (V2.0) was developed based on the QLICD-CHD (V1.0), using a programmed decision procedures. Based on the data measuring QoL 3 times before and after treatments from 189 patients with CHD, the psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness employing correlation analysis, multi-trait scaling analysis, structural equation modeling, t-test and also G-study and D-study of generalizability theory analysis. The SF-36 scale was used as the criterion to evaluate the criterion-related validity. Paired t tests were conducted to evaluate the responsiveness on each domain/facet as well as the total of the scale, with Standardized Response Mean (SRM) being calculated. The QLICD-CHD (V2.0) has been developed with 42 items in 4 domains. The Cronbach's α of the general module, the specific module and the total scale were 0.91, 0.92 and 0.91 respectively. The overall score and the test-retest reliability coefficients in all domains are higher than 0.60, except for the specific module. Correlation and factor analysis confirmed good construct validity and criterion-related validity. After treatments, the overall score and score of all domains have statistically significant changes (P<0.01). The SRM of domain-level score ranges from 0.27 to 0.50. Generalizability Theory further confirm the reliability of the scale through more accurate variance component studies. The QLICD-CHD (V2.0) could be used as a useful instrument in assessing QoL for patients with CHD, with good psychometric properties.

Translation and Adaptation of the Reinjury Anxiety Inventory, the Sport Injury Rehabilitation Adherence Scale, and the Athletic Injury Self-Efficacy Questionnaire Into Turkish.

Psychological difficulties can adversely affect rehabilitation outcomes and make return to sport more difficult. Identifying psychological difficulties is possible with valid and reliable measurement tools. The purpose of this study is to translate and culturally adapt the Reinjury Anxiety Inventory (RIAI), the Sport Injury Rehabilitation Adherence Scale (SIRAS), and the Athletic Injury Self-Efficacy Questionnaire (AISEQ) into Turkish and evaluate the psychometric properties of the Turkish versions. Cross-sectional study. The instruments were forward- and back-translated, culturally adapted, and validated on 248 athletes and 34 physical therapists. The physical therapists of the athletes completed the SIRAS to evaluate the athletes. Statistical analysis included reliability tests (Cronbach alpha and test-retest), exploratory factor analysis, confirmatory factor analysis, and correlational analysis. Floor and ceiling effects (<15%) were also assessed. Confirmatory factor analyses revealed a satisfactory model fit for the RIAI and the AISEQ, and exploratory factor analysis revealed the 1-factor structure for the SIRAS as in the original. All 3 instruments displayed adequate internal consistency (Cronbach alpha coefficients ranged from .84 to .88) and test-retest reliability (coefficients ranged from .81 to .93). Convergent validity of the instruments was supported by significant correlations between the AISEQ and both the RIAI and the SIRAS. Our results suggest that the Turkish versions of the instruments were valid, consistent, and reliable in athletes who have serious injuries. Scores on these instruments could be useful for evaluating the contributions of psychological factors to return to sport following serious injuries. Clinicians are encouraged to use RIAI-Turkish (RIAI-TR), SIRAS-Turkish (SIRAS-TR), and AISEQ-Turkish (AISEQ-TR) together to make decisions about the treatment and rehabilitation plans of injured athletes.

Validation of the "obturator functioning scale" for Chinese-speaking patients with obturator prostheses after cancer-related maxillectomy

ObjectiveThe Obturator Functioning Scale (OFS) is a scale without formal measures of validity in any language. This study aimed to translate and adapt the OFS from English to Chinese and check its reliability and validity in Chinese-speaking patients with obturator prostheses after cancer-related maxillectomy. MethodsThe 15-item Chinese preversion of the OFS was completed by 133 patients in three tertiary stomatological hospitals. Of these, 41 completed it again one week after the first measurement. The patients also completed the Chinese version of the University of Washington quality of life scale (UW-QOL, Version 4). ResultsItem 12 ("upper lip feels numb") was deleted to achieve a better statistical fit. The 14-item Chinese version of the OFS (OFS-Ch) demonstrated high internal consistency (Cronbach's alpha = 0.908). The test-retest reliability coefficients for most items exceeded 0.90, indicating substantial reproducibility. Confirmatory factor analysis found that the scale consisted of three correlated factors: 1) eating (four items), 2) speech (five items), and 3) other problems (five items). This explained 70.2 % of the total variance using exploratory factor analysis. The scale was significantly convergent and discriminant and could validly discriminate between patients with Brown I and IId maxillary defects. ConclusionsOur results showed that the OFS-Ch scale is a valid tool for evaluating oral dysfunction and satisfaction with appearance for patients with the obturator prosthesis and identifying those at risk of poor obturator function in clinical settings.

The Pediatric Quality of Life Inventory™ (PedsQL™) Neuromuscular Module (PedsQL™ 3.0 NM) evaluates the health-related quality of life in children who are affected by neuromuscular diseases. This study's aim is to assess the adaptation of the PedsQL™ 3.0 NM Turkish version (PedsQL™ 3.0 NM-TR) for 2- to 4-year-olds in spinal muscular atrophy (SMA). The procedure of translating the PedsQL™ 3.0 NM into Turkish was conducted in accordance with the translation methodology outlined by the PedsQL™ measurement model. The PedsQL™ 3.0 NM-TR was administered to 54 parents of children with SMA aged 2 to 4 years. The test-retest reliability and intraclass correlation coefficient (ICC) were measured for reliability analysis. Cronbach's α coefficient and item score correlations were calculated for internal consistency. Concurrent construct validity was evaluated by Pearson correlations between the outcomes of the PedsQL™ 4.0 Generic Core Scale (PedsQL™ 4.0 GCS) and the PedsQL™ 3.0 NM. The PedsQL™ 3.0 NM-TR total score shows excellent reliability. The Cronbach's α values for the PedsQL™ 3.0 NM ranged between 0.871 and 0.906, while those for the PedsQL™ 4.0 GCS ranged between 0.843 and 0.897. Test-retest ICC values for the PedsQL™ 3.0 NM-TR ranged between 0.812 and 0.917, and for the PedsQL™ 4.0 GCS ranged between 0.773 and 0.899. The relationship between the PedsQL™ 3.0 NM-TR and the subscores of the PedsQL™ 4.0 GCS demonstrated a range of correlations from excellent to fair, indicating the interplay between two scales. This study established the PedsQL™ 3.0 NM-TR as reliable, valid, and feasible for use in children aged 2 to 4 years with SMA.

Validating the Use of Percent Grammatical Utterances for Assessing Mandarin-Speaking Children's Grammatical Skill: Evidence From 3-Year-Olds.

The study examined the use of percent grammatical utterances (PGUs) for assessing grammatical skills in Mandarin-speaking 3-year-old children. Participants were 30 Mandarin-speaking 3-year-olds with typical development. Language samples were collected in two visits for each child using a picture description task. Children were asked to talk about 16 pictures in response to questions and prompts at each visit. Pictures for the language sample collection were identical across the visits. PGUs were computed, and the grammatical errors that children produced in the task were coded and tallied for error types at each visit. Test-retest reliability, split-half reliability, and concurrent criterion validity of PGUs were evaluated. The mean PGU level was approximately 78% at Visit 1 and 81% at Visit 2, both of which were significantly below the mastery level (i.e., 90%). The correlation coefficient for test-retest reliability of PGU was large (r = .70, p < .01); the correlation coefficient for split-half reliability was medium at Visit 1 (r = .47, p < .01) and large (r = .65, p < .01) at Visit 2. In addition, the correlation coefficient for concurrent criterion validity of PGU was medium for both visits (rs ≥ .35, ps ≤ .03). The ranking and proportion of each error type were similar between the visits. The initial evidence from psychometric properties suggests that PGU computed from the picture description task is a reliable and valid measure for evaluating grammatical skills in Mandarin-speaking 3-year-old children. https://doi.org/10.23641/asha.25395499.

Facioscapulohumeral muscular dystrophy Health Index: Japanese translation and validation study

Purpose The Facioscapulohumeral Muscular Dystrophy Health Index (FSHD-HI) is a patient-reported outcome measure developed for patients with FSHD. This study aimed to translate the FSHD-HI into Japanese (FSHD-HI-J), evaluate cultural adaptation, and examine its psychometric properties. Materials and methods We created two forward translations, integrated them into a single Japanese version, and evaluated the back-translated version of the FSHD-HI. After finalizing the translation and cultural adaptation, we conducted a survey of 66 patients with FSHD to examine the reliability and validity of the FSHD-HI-J. For psychometric evaluations, we used Cronbach’s alpha to assess internal consistency, the intraclass correlation coefficient (ICC) for test-retest reliability, and assessed validity based on the associations between FSHD-HI-J, clinical variables, and quality of life measures. Results The FSHD-HI-J was found to be clinically relevant, indicating high internal consistency and test-retest reliability (ICC = 0.92 [95% confidence interval: 0.86-0.95] for the total score), as well as significant associations with clinical variables (D4Z4 repeats and functional impairment) and other quality of life measures (|rho| = 0.25-0.73). Conclusions The FSHD-HI-J is a valid and reliable patient-reported outcome measure for Japanese patients with FSHD. This validated, disease-specific patient-reported outcome is essential for future clinical practice and clinical trials.

Development of Flood Preparedness Behavior Scale: A Methodological Validity and Reliability Study.

Floods are the most frequent natural disasters with a significant share of their mortality. Preparedness is capable of decreasing the mortality of floods by at least 50%. This paper aims to present the psychometric properties of a scale developed to evaluate the behavior of preparedness to floods in Sudan and similar settings. In this methodological scale development study, experts assessed the content validity of the items of the developed scale. Data were collected from key persons of 413 households living in neighborhoods affected by the 2018 floods in Kassala City in Sudan. A pre-tested questionnaire of sociodemographic data and the Flood Preparedness Behavior Scale (FPBS) were distributed to the participants' houses and recollected. Construct validity of the scale was checked using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency of the scale was checked using Cronbach's alpha. Test-retest reliability was assessed by Pearson's correlation coefficient. Item analyses and tests of significance of the difference in the mean scores of the highest and lowest score groups were carried out to ensure discriminatory power of the scale items. Experts agreed on the scale items. Construct validity of the scale was achieved using EFA by removing 34 items and retaining 25 items that were structured in three factors, named as: measures to be done before, during, and after a flood. Confirmatory factor analysis confirmed the construct obtained by EFA. The loadings of the items on their factors in both EFA and CFA were all > 0.3 with significant associations and acceptable fit indices obtained from CFA. The three factors were found to be reliable in terms of internal consistency (Cronbach's alpha coefficients for all factors were > 0.7) and test-retest reliability coefficient. In item analysis, the corrected total item correlations for all the items were > 0.3, and significant differences in the means of the highest and lowest score groups indicated good item discrimination power. The developed 25 items scale is an instrument which produces valid and reliable measures of preparedness behavior for floods in Sudan and similar settings.

Reliability and validity of the Turkish version of the thirst distress scale-heart failure

AbstractObjective: Patients with heart failure may experience thirst distress. There is, however, no measurement tool to define patients’ thirst distress in Turkey. The study aimed to determine psychometric properties of the translated Turkish version of the Thirst Distress Scale-Heart Failure (TDS-HF) in a sample of heart failure patients. Design: This methodologically planned study was conducted in two different training and research hospitals in Istanbul. Content validity, confirmatory factor analysis and concurrent validity were used in the validity analysis following the language validity analysis. Reliability coefficients were analysed by calculating Cronbach’s alpha, McDonald’s Omega and test-retest reliability coefficients. Validity and reliability analysis involved 116 patients, and test-retest analysis was carried out among 36 patients who volunteered to participate in the study. Results: The patients had a mean age of 55.2 ± 14.9. The factor structure and the examined fit indices of the one-dimensional eight-item scale indicated that the Turkish version of the scale was consistent with the original model. Item-total correlations were between 0.84 and 0.93, Cronbach’s alpha coefficient was 0.90, the test-retest reliability coefficient was 0.97 and the McDonald’s omega coefficient was 0.93, demonstrating that the scale is highly reliable. Conclusion: The Turkish version of the Thirst Distress Scale-Heart Failure was found to be valid and reliable.

Psychometric Properties of the EQ-5D-Y-5L for Children With Intellectual Disability

ObjectivesThe EQ-5D-Y-5L is a generic preference-based measure of health-related quality of life for children. This study aimed to describe the distributional properties, test-retest reliability, and convergent validity of the EQ-5D-Y-5L in children with intellectual disability (ID). MethodsCaregivers of children with ID (aged 4 to 18 years) completed an online survey, including a proxy-report EQ-5D-Y-5L, the Quality-of-life Inventory-Disability, and disability-appropriate measures corresponding to the EQ-5D dimensions: mobility, self-care (SC), usual activities (UA), pain/discomfort (PD), and worry/sadness/unhappiness. Twenty-one participants repeated the EQ-5D-Y-5L a few weeks later. Test-retest reliability was computed using weighted kappa and intraclass correlation coefficients, and convergent validity using Spearman’s and Pearson’s correlation coefficients. ResultsCaregivers of 234 children completed the survey, with <1% missing values. Only 1.7% reported “no problems” on all dimensions (11111). The dimensions with the lowest percentage of “no problems” were SC and UA (both 8%). Test-retest reliability coefficients were fair to substantial for 4 dimensions (weighted kappa .30 to .79) but low for PD and overall health, as measured by the visual analog scale (EQ-VAS). Convergent validity was strong (Spearman’s correlation .65 to .87) for mobility, SC, and PD; moderate to strong for worry/sadness/unhappiness (.47 to .60) and the EQ-VAS (Pearson’s correlation .49); and weak to moderate for UA (.21 to .52). ConclusionsConvergent validity was generally good; test-retest reliability varied. Children with ID had lower scores on SC and UA than other populations, and their EQ-VAS could fluctuate greatly, indicating poorer and less stable health-related quality of life.

Translation and cross-cultural adaptation of Polish version of Neuropathic Pain Questionnaire (NPQ-PL) and its comparisons with different questionnaires.

The aim of this study was to assess the validity and reliability of the Polish version of the Neuropathic Pain Questionnaire (NPQ-PL), and to compare it to other diagnostic tools. Neuropathic pain is a burdensome condition, of which the exact prevalence is difficult to estimate. During initial screening, pain questionnaires are helpful in alerting clinicians about the need for further evaluation. The NPQ-PL has been developed following the guidelines for translation and cultural adaptation. A total of 140 patients with chronic pain (ChP), 90 with neuropathic pain (NP), and 50 with nociceptive pain (NoP), were enrolled into this study. The study group consisted of 60.71% women and 39.29% men; the mean age of patients (standard deviation, SD) was 53.22 years (15.81), and the average NPQ-PL score (SD) was 0.49 (1.27). Statistically significant relationships were found between higher age distribution and greater pain intensity in the NP group compared to the NoP group. There were also significant differences in pain levels between people of different ages, with the predominance in the elderly. Cronbach's alpha coefficient of the whole questionnaire was 0.85 and the intraclass correlation coefficient (ICC) for test-retest reliability was 0.635. Using receiver-operating characteristic (ROC) curve analysis, the area under the curve (AUC) was 0.97 and the best cut-off value was 0.002, which resulted in the highest sensitivity (93.3%) and specificity (96.0%). The NPQ-PL is a valid tool for discriminating between neuropathic and nociceptive pain. It can be used by physicians of various disciplines when assessing patients with ChP of various origins.

Validation of the Chinese version of the diabetes health profile to predict the impact of mobile health education on quality of life in type 2 diabetes patients.

The Diabetes Health Profile (DHP18), initially created in the United Kingdom, currently lacks a Chinese version. This study endeavors to authenticate the Chinese adaptation of the DHP18 and assess the influence of mobile health (mHealth) education intervention on the quality of life of individuals living with diabetes. The study included 470 Type 2 diabetes Mellitus (T2DM) patients (204 men, 266 women), spanning an age range of 19-79 years, with an average age of 54 ± 12.40 years. Data analysis employed Jamovie and Mplus software. Moreover, test-retest reliability was evaluated in 52 hospitalized T2DM patients through two repeated measurements taken 4 weeks apart. The Chinese version DHP18 scale exhibited high reliability, evidenced by a Cronbach's alpha of 0.88, and coefficient of test-retest reliability of 0.84. Individual subscales also demonstrated strong reliability, ranging from 0.76 to 0.84, with test-retest reliability spanning from 0.71 to 0.74. Confirmatory Factor Analysis (CFA) employing a three-factor structure (χ2 = 294.69, GFI = 0.92, TLI = 0.91, RMSEA = 0.05, SRMR = 0.06) validated the scale's construct validity. Notably, there was a statistically significant difference (p < 0.05) in the quality of life between Type 2 diabetes patients using mHealth education intervention and those without mHealth education intervention. Mediation analysis revealed that Appraisal of Diabetes (ADS) and Self-Management Efficacy (SED) mediated the effects of Psychological Distress (PD) and Behavior Adherence (BA) on quality of life, both significant direct and indirect effects (p < 0.001). In addition, Dietary Abstinence (DE) displayed significant overall impact (β = -0.13, p < 0.001) and indirect influence (β = -0.10, p < 0.01) on diabetic patients' quality of life, though lacking a significant direct effect (β = -0.03, p = 0.38). The Chinese version of the Diabetes Health Profile Scale meets stringent psychometric standards and stands as an appropriate measurement tool for Chinese T2DM patients, maintaining comparable results to the original scale's structure. The mHealth education intervention yielded a notably positive impact on the quality of life among T2DM patients. Mediation analysis revealed that the three dimensions of the DHP were mediated by Appraisal of Diabetes and Diabetes Self-Management Efficacy, partially mediated by Psychological Distress and Behavior Adherence, and fully mediated by Dietary Abstinence, providing insight into the positive effects of the mHealth model on the quality of life of diabetic patients.

Norms, convergent validity, test–retest reliability, and practice effects for verbal fluency overall performance, clustering, and switching in Spanish-speaking children

Objective We conducted two empirical studies (in a cross-sectional and a longitudinal design) with the aim at establishing normative data (including norms for strategy use [i.e., clustering and switching strategies] and performance over time), and examining the convergent validity, the test–retest reliability (3–4 wks interval) and the changes in performance with practice (1 year interval) of the different verbal fluency (VF) quantitative and qualitative scores in Spanish-speaking children and adolescents. Method In S1 (n = 620 6- to 15-year-old Spanish-speaking children and adolescents), MANCOVA and Pearson’s correlations were employed. In S2 (n = 148 6- to 12-year-old Spanish-speaking children), intraclass correlation coefficient (ICC), paired t-tests, and Confirmatory Factor Analysis (CFA) were used. Results S1 results showed an age effect on all VF measures (quantitative and qualitative). The number of switches/clusters was more related to total word productivity and to executive functions (EF) than the mean cluster size. In S2, a significant increase in phonological VF performance was observed on number of switches and word productivity scores from baseline (Time 1) to repeat testing at Time 2. Practice effects were observed at Time 3 on all measures except for semantic and phonological mean cluster size. Test–retest reliability coefficients at Time 2 for number of clusters and switches, but not for mean cluster size, fell in the moderate range, ranging from ICCs .61 to ICCs .81. Test–retest reliability coefficients for total word productivity were higher (ICCs above .80) and stronger when testing as a unity with CFA methods (ϕ=.94, p < .001). Conclusions These data may be relevant for informing the neuropsychological assessment of spontaneous cognitive flexibility in children with typical development (TD) and those with developmental or acquired disorders.
