Validity and reliability of the Swedish version of the Children’s Sleep Habits Questionnaire (CSHQ-SWE)

BackgroundTo translate and culturally adapt the Children’s Sleep Habits Questionnaire (CSHQ) to a Swedish version, CSHQ-SWE, and to assess its validity and reliability for use with children with attention deficit hyperactivity disorder (ADHD).MethodsA total of 84 children with ADHD (51 boys and 33 girls; 6–12 years) and parents (7 men and 77 women; 28–51 years) were included in the study. CSHQ was translated and culturally adapted to Swedish, and assessed for concurrent validity with sleep actigraphy (analyzed by Kendall’s Tau) and for reliability by internal consistency (analyzed by McDonald’s Omega H). Face and content validity was evaluated by parents (n = 4) and healthcare professionals (n = 6) qualitatively (comprehensiveness, relevance, and comprehensibility assessed by interviews and analyzed by thematic analysis) and quantitatively (analyzed by content validity ratio and content validity index for 33 items and four non-scored inquiries).ResultsParent-reported sleep problems (CSHQ-SWE total score) were moderately correlated with less “Sleep Efficiency” (Tau = −0.305; p < 0.001) measured by sleep actigraphy. Parent-reported problems with “Sleep Onset Delay” was moderately correlated with measured time for ”Sleep Onset Latency” (Tau = 0.433; p < 0.001). Parent-reported problems with “Night Wakings” were weakly correlated with measured time for “Wake After Sleep Onset” (Tau = 0.282; p < 0.001). Parents estimation of “Total daily sleep duration” was moderately correlated with measured “Total Sleep Time” (Tau = 0.386; p < 0.001). Five of the seven subscales reached an acceptable level for internal consistency (McDonald’s Omega H > 0.700). Comprehensiveness, relevance, and comprehensibility of CSHQ-SWE were satisfactory overall. Content validity ratio was 0.80 to 1.00 for six items, 0.00 to 0.60 for 22 items, and < 0.00 for nine items. Content validity index was 0.22.ConclusionsCSHQ-SWE demonstrated acceptable concurrent validity with objectively measured sleep and internal consistency, whereas the overall results of face and content validity assessment varied. The instrument needs to be further evaluated regarding construct validity, responsiveness, test-retest reliability, and its generalization to other populations.

Development and Initial Validation of a Meniere's Disease Quality of Life Instrument: The MenQOL.

To design and validate a disease-specific quality of life instrument for Meniere's disease. We used a sequential process of expert input, patient focus groups, and analyses of responses to draft questionnaires to create a 24-item Meniere's disease quality of life (MenQOL) instrument. The MenQOL and the SF-36v2 were administered to a cohort of 50 patients with Meniere's disease and 60 comparison patients with tinnitus, vertigo, or hearing loss from other causes identified at a tertiary academic center. We performed exploratory factor analysis, Cronbach's α, between group comparisons of total MenQOL scores, and regression analyses between the MenQOL and SF-36v2 to evaluate the instrument's factor structure, internal consistency, face validity, and external validity. Segregation of the instrument into domains was assessed by exploratory factor analysis. Exploratory factor analysis revealed that the MenQOL has a single domain. Cronbach's α = 0.914 indicated high internal consistency for the instrument as a whole. Mean MenQOL scores showing significantly worse quality of life among patients with Meniere's disease than comparison participants (52.5 ± 15.8 vs. 43.2 ± 12.6; p = 0.0051), indicating good construct validity. Significant inverse relationships in bivariate linear regressions between total MenQOL scores and SF-36v2 physical (slope = -0.94, p < 0.0001) and mental (slope = -1.16, p < 0.0001) composite scores showed acceptable concurrent validity. We have described the initial development of the MenQOL, a simple, valid patient-reported outcome measure that, subject to further study, may be used to assess the effects of treatment on disease-specific quality of life in patients with Meniere's disease. 3 Laryngoscope, 2024.

The caregiver contribution to self-care of stroke inventory (CC-SCSI): evaluation of psychometric characteristics

BackgroundThe caregiver contribution to self-care plays an important role in improving the health outcomes of chronic patients, which needs urgent attention. However, it has been hindered by the lack of a tailored instrument that assesses the caregiver contribution to self-care of stroke.ObjectivesTo test the psychometric characteristics of the caregiver contribution to self-care of stroke Inventory (CC-SCSI) in health care practice.MethodsParticipants were recruited in Henan Province from March 2021 to October 2022, utilizing a multicenter stratified sampling approach. A 23-item self-report CC-SCSI with 3 separate scales measuring caregiver contribution to self-care maintenance of stroke, caregiver contribution to self-care monitoring of stroke and caregiver contribution to self-care management of stroke was tested for validity through discriminant validity, confirmatory factor analysis, concurrent validity and convergent validity. The reliability was tested by Cronbach’s α coefficient and test-retest reliability. Qualitative data were analysed using thematic analysis. A STROBE checklist was used.ResultsThe three scales of the CC-SCSI exhibited good discriminant validity. Confirmatory factor analysis supported the three-factor structure of the Caregiver Contribution to Stroke Self-Care Maintenance and Management scales and the one-factor structure of the Caregiver Contribution to Stroke Self-Care Monitoring scale. The moderate correlation between the CC-SCSI and the Self-Care of Stroke Inventory indicated acceptable concurrent validity. The moderate correlation between the CC-SCSI and the Caregiver Contribution to Self-Care of Chronic Illness Inventory indicated acceptable convergent validity. Cronbach’s αs for the Caregiver Contribution to Self-Care Maintenance, Self-Care Monitoring, and Self-Care Management scales ranged from 0.876 to 0.974. Test-retest reliability showed average ICC values ranging from 0.828 to 0.903 (P < 0.001).ConclusionsThe 23-item CC-SCSI presents good psychometric properties and could be used to explore the caregiver contribution to stroke self-care in health care practice and research.

Concurrent validation of the resistance intensity scale for exercise for monitoring velocity-based training with elastic bands

The aim was to evaluate the concurrent validity and reliability of the Resistance Intensity Scale for Exercise [RISE], which uses verbal descriptors, to quantify the intensity in velocity-based training with elastic bands. Eighteen trained volunteers performed parallel squats at maximum speed at 40%, 55%, 70%, and 85%1RM in four sessions, two for familiarization and two for reliability. Each set was stopped at a 10% intra-set velocity loss. Participants reported the perceived effort (easy-low-moderate-hard-maximal) at the first and last repetition. The concurrent validation was conducted with external load (i.e., mean propulsive velocity, weight, repetitions, and maximum power) and internal load parameters (i.e., heart rate). Participants' relative strength was calculated to assess its influence on the dependent variable. Acceptable concurrent validity and reliability (ICC>0.77, CV<21%) were observed, with the perceived effort being appropriate to differentiate between intensities and not being influenced by the participants’ relative strength (p = 0.88). A categorical linear regression showed significant (p < 0.001) associations between the RISE scores and the weight, repetitions, and mean propulsive velocity (r = 0.43–0.63). The findings certify the usefulness of the perceived exertion for quantifying the intensity during velocity-based training with elastic bands. The perceived exertion of the first and last repetition favors a proper dosage of the training load.

Cross-cultural adaptation and clinical application of the Perth Empathy Scale.

Alterations of empathy have been observed in patients with various mental disorders. The Perth Empathy Scale (PES) was recently developed to measure a multidimensional construct of empathy across positive and negative emotions. However, its psychometric properties and clinical applications have not been examined in the Chinese context. The Chinese version of the PES was developed and administered to a large Chinese sample (n = 1090). Factor structure, internal consistency, test-retest reliability, and convergent, discriminant, as well as concurrent validity were examined. Moreover, 50 patients with major depressive disorder (MDD) and 50 healthy controls were recruited to explore the clinical utility of the PES. Confirmatory factor analyses supported a theoretically congruent three-factor structure of empathy, namely Cognitive Empathy, Negative Affective Empathy and Positive Affective Empathy. The PES showed good to excellent internal consistency reliability, good convergent and discriminant validity, acceptable concurrent validity, and moderate to high test-retest reliability. Patients with MDD had significantly lower PES scores compared to healthy controls. Linear discriminant function comprised of the three factors correctly differentiated 71% of participants, which further verified the clinical utility of the PES. Our findings indicated that the Chinese version of the PES is a reliable and valid instrument to measure cognitive and affective empathy across negative and positive emotions, and could therefore be used in both research and clinical practice.

Confirmatory factor analysis and gender invariance of the Persian version of psychological control scale: association with internalizing and externalizing behavior problems.

The current cross-sectional study aimed to examine the reliability, construct validity, gender invariance and concurrent validity of the psychological control scale-youth self-report (PCS-YSR) among Iranian adolescents. A total of 1,453 high school students (49.2% boys; Mage = 15.48, SD = 0.97), who aged between 14 and 18 years old completed the PCS-YSR and the youth self-report (YSR) scale of behavior problems. Reliability was established using Cronbach's alpha and ordinal alpha for maternal and paternal psychological control. The confirmatory factor analysis (CFA) results supported the original unidimensional model of the PCS-YSR scale for both mother and father forms. Results also revealed that mother and father forms of PCS-YSR were invariant across adolescents' gender. When comparing the mean differences, mothers were more psychologically controlling toward their sons, compared to their daughters. The mother and father forms of PCS-YSR were found to have acceptable concurrent validity through their relationship to internalizing and externalizing behavioral problems. Overall, our findings supported the psychometric properties of the Persian version of the Psychological Control Scale-Youth Self-Report among Iranian adolescents. This scale can be used as an efficient tool for parental psychological control among adolescents in Iran. The negative effect of the intrusive parenting behavior on child' negative outcomes in Iran, irrespective of culture, was shown.

Test–Retest Reliability and Concurrent Validity of the 30 second Sit to Stand Test in Adolescents

ABSTRACT The purpose of our study was to assess the test–retest reliability and concurrent validity of the 30 sec Sit to Stand test in a sample of adolescents. We recruited 30 male (58%) and 22 female (42%) participants (mean age = 15.77 years ± 0.46). Participants completed the 30-sec Sit to Stand and standing long jump tests on two occasions separated by 1 week. The rank order repeatability of the Sit to Stand test for the entire group was good (ICC = 0.84, 95% CI’s [0.71 to 0.91]), systematic error was low (1.7 repetitions ± 2.9), and the typical error between tests was 2.1 repetitions (95% CI’s 1.73 to 2.55). Sit to Stand results were significantly associated with lower body power (r = 0.55, p < .001). Our study demonstrated that the 30-sec Sit to Stand test has moderate-to-high test–retest reliability and acceptable concurrent validity in a population of adolescents.

A Parent Version of the Motors of COVID-19 Vaccination Acceptance Scale for Assessing Parents' Motivation to Have Their Children Vaccinated.

Parents' motivation to vaccinate their children against coronavirus disease 2019 (COVID-19) plays a crucial role in the uptake of COVID-19 vaccines among children. The Motors of COVID-19 Vaccination Acceptance Scale (MoVac-COVID19S) is a valuable tool for assessing individuals' vaccination-related attitudes and the factors influencing their decision to be vaccinated against COVID-19. This study adapted the MoVac-COVID19S to create a parent version (P-MoVac-COVID19S) and examined the psychometric soundness of two P-MoVac-COVID19S versions (a 9-item version (P-MoVac-COVID19S-9) and a 12-item version (P-MoVac-COVID19S-12)) for assessing parents' motivation to vaccinate their children. A total of 550 parents completed the P-MoVac-COVID19S and a questionnaire assessing the factors that impact parents' intention to allow their children to receive the COVID-19 vaccine using a vaccine acceptance scale. We enquired about the level of parental worry regarding the adverse effects of COVID-19 vaccines on children's health and the number of COVID-19 vaccine doses received by parents. The factor structures of the P-MoVac-COVID19S-9 and P-MoVac-COVID19S-12 were examined using confirmatory factor analysis. The internal consistency, test-retest reliability, and concurrent validity of the P-MoVac-COVID19S were also examined. The results revealed that the P-MoVac-COVID19S-12 has a four-factor structure, which aligns well with the theoretical framework of the cognitive model of empowerment; the P-MoVac-COVID19S-9 has a one-factor structure. Both the P-MoVac-COVID19S-9 and P-MoVac-COVID19S-12 had good internal consistency and test-retest reliability and acceptable concurrent validity. The results of this study demonstrated that the P-MoVac-COVID19S is a reliable and valid instrument for assessing parent's motivation to vaccinate their children against COVID-19.

Validity and reliability of the Sinhalese version of the perceived stress scale questionnaire among Sri Lankans.

Despite the availability of validated psychometrics tools to assess depression, there has not been any validated and reliable tool established to test perceived stress among Sri Lankans. The objective of this study is to test the validity and reliability of the Sinhalese Version of the Sheldon Cohen Perceived Stress Scale. Standard and systematic procedures were adopted to translate the original English version of the Perceived Stress Scale-10 questionnaire into Sinhalese. Consecutive sampling was employed to recruit the Type 2 Diabetes mellitus (T2DM) sample (n = 321), and a convenient sampling was used to recruit the Age and Sex matched Healthy Controls (ASMHC) (n = 101) and the Healthy Community Controls (HCC) groups (n = 75). Cronbach alpha was used to assess internal consistency and reliability was determined using test-retest method utilizing Spearman's correlation coefficient. Sensitivity was evaluated by comparing the mean scores of the Sinhalese Perceived Stress Scale (S-PSS-10) and Sinhalese Patient Health Questionnaire (S-PHQ-9) scores. Post-hoc comparisons were done using Bonferroni's method. Mean scores were compared between the T2DM, ASMHC, and HCC groups using the independent t-test. Explanatory Factor Analysis (EFA) was conducted using the principal component and Varimax rotation while the Confirmatory Factor Analysis (CFA) was performed to assess the goodness-of-fit of the factor structure extracted from the EFA. Concurrent validity was assessed using the Pearson correlation between the S-PSS-10 and Patient Health Questionnaire measured by S-PHQ-9 (p < 0.05). Cronbach alpha values of the three groups T2DM, ASMHC and HCC were 0.85, 0.81, and 0.79, respectively. Results of the ANOVA test suggested that there was a significant difference in the mean scores between groups (p < 0.00). EFA analysis revealed the existence of two factors with eigenvalues greater than 1.0. The factor loadings for the items ranged from 0.71-0.83. The CFA analysis demonstrated a good model fit for the two-factor model S-PSS-10. The S-PSS-10 significantly correlated with S-PHQ-9, indicating an acceptable concurrent validity. Findings revealed that the S-PSS-10 questionnaire can be used to screen perceived stress among the majority of the Sri Lankan Sinhalese-speaking population specially with chronic illnesses. Further studies with higher sample sizes across different populations would enhance the validity and reliability of S-PSS-10.

Reliability and validity of the Körperkoordinationstest Für Kinder in Chinese children.

The Körperkoordinationstest Für Kinder (KTK) is a reliable and low-cost motor coordination test tool that has been used in several countries. However, whether the KTK is a reliable and valid instrument for use in Chinese children has not been assessed. Additionally, because the KTK was designed to incorporate locomotor, object control, and stability skills, and there is a lack of measurement tools that include stability skills assessment for Chinese children, the KTK's value and validity are worth discussing. A total of 249 primary school children (131 boys; 118 girls) aged 9-10 years from Shanghai were recruited in this study. Against the Test of Gross Motor Development-3 (TGMD-3), the concurrent validity of the KTK was assessed. We also tested the retest reliability and internal consistency of the KTK. The test-retest reliability of the KTK was excellent (overall: r = 0.951; balancing backwards: r = 0.869; hopping for height: r = 0.918; jumping sideways: r = 0.877; moving sideways: r = 0.647). Except for the boys, the internal consistency of the KTK was higher than the acceptable level of Cronbach's α > 0.60 (overall: α = 0.618; boys: α = 0.583; girls: α = 0.664). Acceptable concurrent validity was found between the total scores for the KTK and TGMD-3 (overall: r = 0.420, p < 0.001; boys: r = 0.411, p < 0.001; girls: r = 0.437, p < 0.001). The KTK is a reliable instrument for assessing the motor coordination of children in China. As such, the KTK can be used to monitor the level of motor coordination in Chinese children.

The Thai Internalized HIV-related Stigma Scale.

Internalized stigma among people living with HIV has been linked to a range of negative consequences. The current study describes the development and validation of a contextually appropriate internalized HIV-related Stigma Scale for people living with HIV in Thailand. The study was carried out in two stages from 2018 to 2019: developing items based on the findings of focus group discussions and pilot testing the original list of items and validating the instrument. In the cross-sectional survey stage, a sample of 400 people living with HIV was used to validate the test items in accordance with their psychometric characteristics. The study's outcome was the 22-item Thai Internalized HIV-related Stigma Scale (Thai-IHSS). The exploratory factor analysis showed that the Thai-IHSS consisted of four components: negative thoughts toward self (5 items), anticipated negative thoughts (7 items), effects of negative thought toward self (6 items), and effects of negative thoughts toward family and access to healthcare services (4 items). The Thai-IHSS had acceptable concurrent, convergent, and congruent validity according to the findings. Additionally, the 8-item Thai-IHSS brief, which included two items for each component, was detailed. The Thai-IHSS is valid and reliable for use in Thailand and other countries with comparable sociocultural environments.

Normative Values and Psychometric Properties of EQ-5D-Y-3L in Chilean Youth Population among Different Weight Statuses.

This study aimed to provide population norms among children and adolescents in Chile using the EQ-5D-Y-3L questionnaire and to examine its feasibility and validity among body weight statuses. This was a cross-sectional study in which 2204 children and adolescents (aged 8-18 years) from Chile completed a set of questionnaires providing sociodemographic, anthropometric and health-related quality of life (HRQoL) data using the five EQ-5D-Y-3L dimensions and its visual analogue scale (EQ-VAS). Descriptive statistics of the five dimensions and the EQ-VAS were categorized into body weight status groups for the EQ-5D-Y-3L population norms. The ceiling effect, feasibility and discriminant/convergent validity of the EQ-5D-Y-3L were tested. The dimensions of the EQ-5D-Y-3L questionnaire presented more ceiling effects than the EQ-VAS. The validity showed that the EQ-VAS could discriminate among body weight statuses. However, the EQ-5D-Y-3L index (EQ-Index) demonstrated a non-acceptable discriminant validity. Furthermore, both the EQ-Index and the EQ-VAS presented an acceptable concurrent validity among weight statuses. The normative values of the EQ-5D-Y-3L indicated its potential use as a reference for future studies. However, the validity of the EQ-5D-Y-3L for comparing the HRQoL among weight statuses could be insufficient.

Rating of perceived difficulty scale for measuring intensity of standing balance exercises in individuals with vestibular disorders.

A method for prescribing the difficulty or intensity of standing balance exercises has been validated in a healthy population, but requires additional validation in individuals with vestibular disorders. This study validated the use of ratings of perceived difficulty for estimation of balance exercise intensity in individuals with vestibular disorders. Eight participants with a confirmed diagnosis of a vestibular disorder and 16 healthy participants performed two sets of 16 randomized static standing exercises across varying levels of difficulty. Root Mean Square (RMS) of trunk angular velocity was recorded using an inertial measurement unit. In addition, participants rated the perceived difficulty of each exercise using a numerical scale ranging from 0 (very easy) to 10 (very difficult). To explore the concurrent validity of rating of perceived difficulty scale, the relationship between ratings of perceived difficulty and sway velocity was assessed using multiple linear regression for each group. The rating of perceived difficulty scale demonstrated moderate positive correlations RMS of trunk velocity in the pitch (r = 0.51, p < 0.001) and roll (r = 0.73, p < 0.001) directions in participants with vestibular disorders demonstrating acceptable concurrent validity. Ratings of perceived difficulty can be used to estimate the intensity of standing balance exercises in individuals with vestibular disorders.

A Newly Developed Scale for Assessing Experienced and Anticipated Sexual Stigma in Health-Care Services for Gay and Bisexual Men.

Gay and bisexual men's experiences and worries of sexual stigma by health-care providers may delay them from seeking health-care assistance. Our study developed the Experienced and Anticipated Sexual Stigma Scale in Health-care Services (EASSSiHS) and examined its psychometric properties. The six-item EASSSiHS was first developed on the basis of the results of focus group interviews with 24 participants. Parallel analysis was used to determine the number of factors. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to examine the factor structure. The internal consistency was examined using McDonald's omega coefficient. Concurrent validity was examined using Pearson correlations with perceived sexual stigma from family and friends, depression, anxiety, and loneliness. The results of parallel analysis and EFA indicated that the factor structure of the EASSSiHS included two factors: experienced stigma and anticipated stigma. The result of CFA further confirmed the two-factor structure. The EASSSiHS had good internal consistency and acceptable concurrent validity. The anticipated stigma factor had stronger associations with perceived sexual stigma from family members and friends, depression, anxiety, and loneliness, when compared with the experienced stigma factor. The results of this study supported the psychometric properties of the EASSSiHS for assessing experienced and anticipated sexual stigma in health-care services among gay and bisexual men. The experience and worry of sexual stigma in health-care services were not rare among gay and bisexual men; therefore, interventions to enhance the cultural competency of health-care workers are urgently required.

The compassionate love for humanity scale (CLS-H-SF): psychometric properties of the Persian version

Compassionate love is beneficial in a variety of domains, including in education, health, and law, as well as in people’s personal lives. The topic of compassionate love has therefore attracted growing interest from researchers interested in its psychological and social dimensions. Given the importance of compassion to the education and health sectors, and the expansion of these sectors in Iran, this paper aims to provide Persian (Farsi) speaking practitioners and researchers with an effective instrument for measuring compassion. As such, the authors have translated the compassionate love for humanity scale-short form (CLS-H-SF) into the Persian language, and assessed the psychometric properties of this instrument among a sample of the Iranian population. A sample of 827 adults (49.9% women and 51.1% men) completed the Persian version of the CLS-H-SF through an online survey. Concurrent validity was assessed using the Persian versions of the positive and negative affect scale, self-esteem scale, and satisfaction with life scale. The CLS-H-SF positively correlated with positive affect, self-esteem and life satisfaction, and negatively correlated with negative affect. These findings indicate acceptable concurrent validity for the CLS-H-SF. Cronbach’s alpha for the scale was 0.88, indicating good internal consistency between items. A confirmatory factor analysis supported a one-factor model same as the English version of the CLS-H-SF. The findings of this study showed the Persian version of CLS-H-SF had acceptable validity and reliability in assessing compassionate love for humanity in Iranian adults.

Bristol Breastfeeding Assessment Tool-Thai Version: Translation, Validity, and Reliability.

In 2019, 14.0% of infants in Thailand were exclusively breastfed up to 6 months of age. To increase exclusive breastfeeding, an objective assessment measure would be useful to maternity care providers for appraising the problems encountered by new mothers' experiences with breastfeeding. To translate the Bristol Breastfeeding Assessment Tool from English into Thai; to assess the reliability and validity of the Thai Bristol Breastfeeding Assessment Tool; and to explore the relationship of a mother's self-efficacy to successful breastfeeding. Using a methodological design, we purposively sampled 302 new mothers from two tertiary hospitals in Thailand who had given birth to a single baby with an uncomplicated vaginal birth. The Thai Bristol Breastfeeding Assessment Tool's structure was examined using confirmatory factor analysis. Concurrent and convergent validity were assessed using the Thai LATCH instrument and Thai Breastfeeding Self-Efficacy Scale, respectively. The inter-item Thai Bristol Breastfeeding Assessment Tool correlation coefficients were positive and strong. The correlation between scores of the Thai Bristol Breastfeeding Assessment Tool and Thai LATCH instrument were positive and strong and had acceptable concurrent validity. The confirmatory factor analysis model fit the Thai Bristol Breastfeeding Assessment Tool data perfectly and the Cronbach's alpha coefficient had acceptable internal reliability. The Thai Bristol Breastfeeding Assessment Tool is a cross-culturally translated instrument equivalent to its English version and demonstrated acceptable validity and reliability. The instrument provides a mechanism for an objective assessment and monitoring system of optimal breastfeeding practices in Thai mothers with newborns.

Initial Development and Psychometric Evidence of Physical Education Grit Scale (PE-Grit).

BackgroundGrit is a key concept in positive psychology and educational science. The construct measures two related constructs that are interest and effort. Several instruments have been developed to measure this construct in professional and educational contexts, but no tools have been developed considering specific contexts such as physical education and sport.ObjectivesThe objective of this study is to develop and test a measurement scale to assess Grit in the context of physical education and sport.MethodsTwo exploratory (Phase 1) and confirmatory (Phase 2) samples were administered the 16-item PE-Grit scale in Arabic. In addition, the confirmatory sample also was administered the R-SPQ-2F two-factor learning approaches scale. The factor structure was examined first by exploratory factor analysis on the first sample and then by confirmatory factor analysis on the second sample. Reliability testing was performed by checking internal consistency simultaneously by the three indices: McDonald's ω, Cronbach's α and Gutmann's λ6. Concurrent validity was checked by Pearson's correlation between the PE-Grit and the two dimensions of the SPQ-2F.ResultsAfter the exploratory factor analysis, which identified the factors and gave a preliminary validation of the designed instrument, confirmatory factor analysis was performed on three hierarchical models to be able to identify the best fitting model. A third-order hierarchical model with two physical and academic components each formed by interest and effort presented the best fit indices: chi X2 = 192.95 (p < 0.01), and the X2/DF = 1.36; GFI = 0.99; AGFI = 0.99; CFI and TLI close to 1; RMSEA = 0.025. In addition, McDonald's ω, internal consistency, and Gutmann's λ6 ranged from 0.78 to 0.86 for all four scale dimensions.ConclusionThe PE-Grit scale displays adequate factor structure, good reliability, and acceptable concurrent validity and can be administered to assess Grit in physical education and sport students.

Validation of a developmental screening checklist for Chinese preschoolers in Hong Kong

ABSTRACT There are concerns about the cultural validity of applying developmental screeners developed and normed in Western countries to other sociocultural contexts. Given the scarcity of culturally validated developmental checklists for use among Chinese children, the Hong Kong Society for the Protection of Children (HKSPC) has developed the HKSPC Developmental Checklist (HKSPC-DC) for preschool teachers to identify children at risk of developmental delays through daily observation of children’s functioning at school. This study explored the psychometric properties of the HKSPC-DC among 1183 preschool children aged 2–6 recruited from 14 nursery schools in Hong Kong. The HKSPC-DC showed excellent internal consistency, good interrater and test–retest reliabilities, and acceptable concurrent validity when correlated with the Taipei City Developmental Checklist for Preschoolers (Taipei II), which is the only screening instrument developed in a Chinese society and validated across 4- to 72-month-olds. The HKSPC-DC also showed good discriminatory power in identifying preschoolers potentially at risk of developmental delays. This screening tool may help facilitate early identification of children with developmental vulnerabilities in Chinese preschool populations.

Translation and validation of Chinese version of sense of competence in dementia care staff scale in healthcare providers: a cross-sectional study

BackgroundHealthcare providers’ dementia-care competence is crucial for quality dementia care. A reliable and valid instrument is needed to assess the gaps in their dementia-care competence, and thereby identifying their educational needs. Therefore, this study aims to translate the 17-item Sense of Competence in Dementia Care Staff (SCIDS) scale into Chinese (SCIDS-C) and to validate the SCIDS-C among Chinese healthcare providers.MethodsThe translation procedure followed the modified Brislin’s translation model. A cross-sectional survey was conducted using the translated version. The validity, including content validity, confirmatory factor analysis, concurrent validity and known-groups validity, was tested. Reliability in terms of internal consistency and test-retest reliability with a 2-week interval was evaluated.ResultsA total of 290 healthcare providers in 12 nursing homes and a hospital completed the survey. The scale-level content validity index was .99. The confirmatory factor analysis model marginally supported the original 4-factor structure. Positive but weak correlations were noted between the total score of the SCIDS-C and that of the Dementia Knowledge Assessment Scale (r = .17, p = .005) and Approaches to Dementia Questionnaire (r = .22, p < .001), suggesting acceptable concurrent validity. Differences between health professionals and care assistants were significant in two subscales scores. The internal consistency of the scale was high, with Cronbach’s α of .87. Test-retest reliability was demonstrated with intra-class correlation coefficient of 0.88.ConclusionsThe SCIDS-C demonstrated acceptable reliability and validity although the known-groups validity between health professionals and care assistants was not fully established. It can be used to measure the level of sense of competence and as an outcome measure in educational intervention aiming at improving dementia care among Chinese healthcare providers.

Validity of self-reports of medication treatment of depression in general population surveys.

To assess the concurrent validity of a single question on medication use for depression in a general population survey. Using data from 2015 to 2016 and 2017 to 2018 National Health and Nutrition Examination Survey, we compared responses to a single question on medication use for depression with responses to a detailed questionnaire confirmed by inspecting medication packages or pharmacy printouts. There was a strong agreement (96.4%) between response to a single question about using medication for depression and responses to questions about using antidepressants or other psychiatric medications for depression on the detailed questionnaire. The single-question assessment had excellent sensitivity (93.8%) and specificity (96.7%), positive predictive value (71.5%), and kappa (0.79). Psychometric properties were mostly consistent across population subgroups. Single-question assessments of medication use for depression have acceptable concurrent validity against more detailed assessments and provide an efficient method for assessing medication treatment of depression in population health surveys.
