‘It was aimed to establish the validity and reliability of the “Mothers’ Breastfeeding Empowerment Scale”’.

Content validity was evaluated with the content validity index (CVI) agreed upon by experts. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used for construct validity. Before factor analysis, the sample size was decided using KMO and Bartlett’s Sphericity test. For the reliability study of the scale, Cronbach’s Alpha coefficient and total score correlation coefficients of parallel forms were examined.

While 49.9% of the infants were between 4–6 months old, the average age of the infants was determined as 3.64 ± 1.77. 70.6% of the mothers were between the ages of 26–43 and the average age of the mothers was 28.83 ± 5.38. In the factor analysis it was found that item loadings of the scale was between 0.57 and 0.95. Also, the fit values of the scale were within acceptable limits. Additionally, it was determined that there was a high-level positive relationship between the scale used for the parallel form and our scale.

The use of the scale in Turkish society is valid and reliable. Validity and reliability analyses support this.

Gender dysphoria is linked to various psychosocial challenges in adolescence, underscoring the need to identify and support youth experiencing gender-related distress. Although gender identity exists on a spectrum beyond the binary, no validated tool currently exists in Turkey that uses inclusive, gender-neutral language to assess it in adolescents.

This study aimed to evaluate the psychometric properties of the Turkish adaptation of the Utrecht Gender Dysphoria Scale–Gender Spectrum (UGDS-GS) among clinical- and community-based adolescents.

A total of 240 participants aged 12–23 years were included. The validity of UGDS-GS was assessed through content validity and confirmatory factor analysis. Reliability was measured using Cronbachʼs alpha and test–retest intraclass correlation coefficient (ICC). A sociodemographic data form, UGDS, UGDS-GS, Rosenberg Self-Esteem Scale (RSES) and Youth Self-Report (YSR) were utilised.

Findings demonstrated strong content validity, with a content validity Index of 0.69, and robust construct validity, indicated by a comparative fit index of 0.993 and a root-mean-square error of approximation of 0.071 following the exclusion of three items. UGDS-GS effectively differentiated scores across demographic groups, showing significant variances based on assigned gender and age. The scale also exhibited excellent criterion validity, evidenced by an area under the curve of 0.947 in receiver operating characteristic analysis, with high sensitivity (80%) and specificity (95.9%) at an optimal cut-off value of 42.50. With a Cronbachʼs alpha of 0.935, UGDS-GS demonstrated strong internal consistency and substantial test–receiver operating characteristic retest reliability (ICC 0.884), alongside notable but weak correlations with several RSES subscales and low to moderate correlations with YSR scores.

These results affirm that tUGDS-GS is valuable and reliable in assessing gender dysphoria in Turkish adolescents. Further research is warranted to improve applicability in diverse contexts and populations.

This study aimed at assessing the validity and reliability of the Turkish version of the Spiritual Health Scale-Short Form (SHS-SF).

The methodological research was conducted with Turkish nursing students (n = 310). The sociodemographic question form and the SHS-SF were used as data collection instruments. The Content Validity Index, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analyses (CFA) were used for the validity of the scale, and Internal Consistency and Cronbach's Alpha reliability coefficient for its reliability.

The EFA revealed that five factors accounted for 66.49% of the variance. According to the CFA, the factor loadings for the 24-item scale ranged from 0.40 to 0.91. Goodness-of-fit indices were as follows: χ2/df = 2.39, RMSEA = 0.06, CFI = 0.92, TLI = 0.91, IFI = 0.92. The item-total correlation for the scale items ranged from 0.37 to 0.65. The alpha coefficient for the scale was 0.91.

It is important to identify the level of spiritual health of nurses and nursing students with a valid and reliable scale. The SHS-SF was found to be a reliable and valid scale for use in the Turkish language and culture. The scale can be used for evaluating spiritual health levels among Turkish nurses and nursing students. This will provide an opportunity for planning appropriate interventions to improve the spiritual health level of nurses and nursing students.

This study aimed to carry out the validity and reliability study for the adaptation of the Competencies for Disaster Nursing Management Questionnaire (CDNMQ), which was developed by Al Thobaity and others in 2016, (https://pubmed.ncbi.nlm.nih.gov/26778698/) to Turkish, and to be able to use in the nursing literature.

This study was conducted in a methodological approach. The scale used in this study was a 10-point Likert scale with 43 items and 3 subfactors. The questionnaire was applied to 450 nurses. The validity and reliability of the scale were evaluated using the exploratory and confirmatory factor analysis. The content validity index was measured within the scope of the internal consistency measurements, and the Pearson’s product-moment correlation coefficient was examined for the test-retest.

The content validity index score was found to be 0.98. As a result of the confirmatory factor analysis of the CDNMQ, it was found that the 3-factor structure of the scale was valid and the goodness of fit tests was appropriate.

The findings have shown that the CDNMQ study is similar to the original scale and an adequate measurement tool in determining competencies in disaster nursing management.

This study aims to determine the psychometric properties of the World Health Organization Well-Being Index (WHO-5) Turkish version in Turkish adults and older adults.

This is a multicenter cultural adaptation study carried out with 1752 participants. Internal consistency (by Cronbach’s alpha); Construct validity (by known groups and confirmatory factor analysis-CFI) and discriminant validity are evaluated stratified by adults and older adults. Cohen’s Effect Size is used in known groups and discriminant validity analyses.

Distribution properties of the WHO-5 Turkish version are in acceptable limits. Alpha values are 0.81 for adults and 0.86 for older adults. The variances of the 58.5% of the adults sample and 63.9% of the older adults sample are explained in Exploratory FA. Model fits (CFI) are satisfactory ( > 0.95) in both samples; but RMSEA is poor in the older adults sample (0.166) whereas it is acceptable (0.073) in the adults sample. Known groups validity and discriminant analyses are satisfactory in both adults and older adults.

The WHO-5 Turkish version has a good measurement capacity, internal consistency and good model fits in both samples. The error values in the older adults group suggest that the results when testing older adults should be interpreted with caution.

There are no tested methods for conducting epidemiological studies of autism spectrum disorders (ASDs) in adult general population samples. We tested the validity of the Autism Diagnostic Observation Schedule module-4 (ADOS-4) and the 20-item Autism-Spectrum Quotient (AQ-20).

Randomly sampled adults aged ⩾16 years were interviewed throughout England in a general population multi-phase survey. The AQ-20 was self-completed by 7353 adults in phase 1. A random subset completed phase 2, ADOS-4 assessments (n=618); the probability of selection increased with AQ-20 score. In phase 3, informant-based Diagnostic Interview Schedule for Social and Communication Disorders (DISCO) and Autism Diagnostic Interview – Revised (ADI-R) developmental assessments were completed (n=56). Phase 1 and 2 data were presented as vignettes to six experienced clinicians (working in pairs). The probability of respondents having an ASD was compared across the three survey phases.

There was moderate agreement between clinical consensus diagnoses and ADOS-4. A range of ADOS-4 caseness thresholds was identified by clinicians: 5+ to 13+ with greatest area under the curve (AUC) at 5+ (0.88). Modelling of the presence of ASD using 56 DISCO assessments suggested an ADOS-4 threshold in the range of 10+ to 13+ with the highest AUC at ADOS 10+ to 11+ (0.93–0.94). At ADOS 10+, the sensitivity was 1 [95% confidence interval (CI) 0.59–1.0] and the specificity 0.86 (95% CI 0.72–0.94). The AQ-20 was only a weak predictor of ADOS-4 cases.

Clinically recommended ADOS-4 thresholds are also recommended for community cases: 7+ for subthreshold and 10+ for definite cases. Further work on adult population screening methods is needed.
