This study aims to adapt the Economic Measures Index (EMI) in Turkish. EMI was developed by Conger et al. (1990) in order to measure couples/romantic partners' economic problems. It consists of independent subscales that measure economic hardship comprehensively. These subscales include economic hardship (indicators of family economic conditions and negative economic events), economic pressure (can't make ends meet, material needs and financial cutbacks) and financial concerns. Participants consisted of 278 students (152 girls and 126 boys) from 6th, 7th and 8th grades (secondary schools) and 9th, 10th and 11th grades (high schools) and their mothers and fathers. The Economic Strain Scale (ESS) developed to assess how often students experienced economic strain in their life were used to test the criterion validity of the EMI. The correlation coefficients between the EMI and ESS ranged between .25 and .31. The Cronbach's Alpha internal consistency coefficients of the subscales of the EMI ranged from 80 to .91. The split-half reliability coefficients of subscales ranged between .76 and .88. The analyses showed that the Turkish form of the EMI had sufficient validity and reliability values.

Scale Properties

This study evaluated the psychometric properties of the Relative Mastery Scale (RMS). Valid and reliable client-centered instruments support practice in value-based health care and community-based settings. Participants were 368 community-dwelling adults aged 18 to 95 years. Researchers conducted validity and reliability examinations of the RMS using classical test theory and Rasch measurement model. A partial credit model allowed exploration of individual scale properties. Spearman’s correlation coefficients between items were statistically significant at the .01 level. Cronbach’s alpha coefficient was .94 showing strong internal consistency. In exploratory factor analysis, Factor 1 accounted for 71% of variance with an eigenvalue of 4.26. In Rasch analysis, the 5-point rating scale demonstrated adequate functioning, confirmed unidimensionality, and person/item separation. The RMS instrument demonstrates sound psychometric characteristics. A valid and reliable measure of internal occupational adaptation supports application to monitor progress of internal occupational adaptation across a variety of individuals.

The topic of metamemory had attracted the attention of many researchers and scholars in the field of educational and cognitive psychology, especially how individuals become aware of and control their memory functions. Therefore, the aim of the present study was to build a psychometric scale/questionnaire for measuring metamemory. The study was conducted among a sample of 200 students joining Sharia/Islamic Law, Arabic Language, Education, English Language, Science, Economics and Management at Al Qassim University. For the purpose of the content validity of the scale, it was verified by the raters’ agreement and the internal consistency of the items of the scale. Pearson correlation coefficient was also used to calculate correlation coefficients between the scores of each item and its dimension to ensure consistency and homogeneity of the items and dimensions of the scale. The correlation coefficients of the items of the scale and the total score of the dimension to which the items belong were all positive correlation coefficients and statistically significant at the level of 0.01, which confirms the consistency and homogeneity of the items of each dimension. The homogeneity of the dimensions of the scale was also verified by calculating Pearson correlation coefficients between the score of each dimension and the overall score of the scale. The reliability of the scale and its sub- dimensions was verified using the α- Cronbach Alpha coefficient. The results showed that the scale and its sub- dimensions had high and statistically acceptable validity and reliability coefficients. Such result indicates that the scale is statistically valid and reliable.

The validity analysis of the scale for the data collected was performed with exploratory factor analysis and item-total correlation tests, while the property of reliability was determined using the Cronbach’s alpha internal consistency coefficient and the stability test was carried out by determining the relationship between two applications conducted at an interval of the five weeks. The scale, which is called the “Scale for Determining the Civic-Mindedness Levels of Individuals” is a five-step Likert-type scale and consists of 27 items that can be collected under three factors. The factor names are “Openness to Criticism/Development”, “Participation/Activeness” and “Lack of Prejudice/Flexibility”. The KMO value of the scale was 0.956; and the Bartlett Test values were x2=11001.719; sd=351; p<0.000. Items in the scale accounted for 56.619% of the total variance. As a result of the confirmatory factor analysis, the χ2 value was 808.07 and the degree of freedom was 321. Χ2/df is 2.51. The fit indices of the scale were determined as RMSEA=0.067; S-RMR=0.049; NFI=0.97. The item-total corrected correlation coefficients of the items in the scale varied between 0.40 and 0.703 (p<.01). The reliability coefficient of the scale was Cronbach’s alpha at 0.954 and the stability coefficients of the items were between 0.496 and 0.674 (p<,01).

Reliability Indicators

The accurate assessment of the mean concentric barbell velocity (MCV) and its displacement are crucial aspects of resistance training. Therefore, the validity and reliability indicators of an easy-to-use inertial measurement unit (VmaxPro®) were examined. Nineteen trained males (23.1 ± 3.2 years, 1.78 ± 0.08 m, 75.8 ± 9.8 kg; Squat 1-Repetition maximum (1RM): 114.8 ± 24.5 kg) performed squats and hip thrusts (3–5 sets, 30 repetitions total, 75% 1RM) on two separate days. The MCV and displacement were simultaneously measured using VmaxPro® and a linear position transducer (Speed4Lift®). Good to excellent intraclass correlation coefficients (0.91 < ICC < 0.96) with a small systematic bias (p < 0.001; ηp2 < 0.50) for squats (0.01 ± 0.04 m·s−1) and hip thrusts (0.01 ± 0.05 m·s−1) and a low limit of agreement (LoA < 0.12 m·s−1) indicated an acceptable validity. The within- and between-day reliability of the MCV revealed good ICCs (0.55 < ICC < 0.91) and a low LoA (<0.16 m·s−1). Although the displacement revealed a systematic bias during squats (p < 0.001; ηp2 < 0.10; 3.4 ± 3.4 cm), no bias was detectable during hip thrusts (p = 0.784; ηp2 < 0.001; 0.3 ± 3.3 cm). The displacement showed moderate to good ICCs (0.43 to 0.95) but a high LoA (7.8 to 10.7 cm) for the validity and (within- and between-day) reliability of squats and hip thrusts. The VmaxPro® is considered to be a valid and reliable tool for the MCV assessment.

Adverse Health Effects

Abstract Violence as a serious health problem and one of the main manifestations of gender inequality brings about adverse health effects for women. Therefore, it is of utmost importance to recognize the reproductive health status of women subjected to violence in order to provide the health services they need. Considering that one of the ways to determine reproductive health status is the use of valid questionnaires in this field, the present study was conducted based on a mixed-method design. The first part of the study (qualitative section) was conducted based on conventional content analysis. In this part, unstructured in-depth interviews were conducted with 18 violated women and 9 experts. In the next stage, the item pool was formed and the Reproductive Health Needs of Violated Women Scale (RHNVWS) was designed based on the review of the literature and the results of the qualitative section with 39 items using the Waltz approach. For psychometric assessment of the above instrument, face and content validity, item analysis, and construct validity were examined using exploratory factor analysis. Based on the results of factor analysis, the four following factors were extracted with a total variance of 47.62: "men's participation", "self-care", "support and health services", as well as "sexual and marital relationships. The internal consistency of the instrument was calculated at α = 0.70–0.89 and α = 0.94 for different constructs and the whole instrument, respectively. Moreover, intra-cluster correlation coefficients were obtained at ICC = 0.96–0.99 and ICC = 0.98 for constructs and the whole instruments, respectively. Based on the results of the current study, the RHNVWS is a tool that specifically assesses the reproductive health needs of violated women and has appropriate validity and reliability. The results of the assessment using the aforementioned instruments can be of great help in promoting the reproductive health of women subjected to violence.

The current research aims to evaluate the reliability and validity of the Hindi Child Perception Questionnaire (CPQ11–14) in a child population of India. A randomly selected sample of children aged 11–14 years (n = 331) and their parents completed the Hindi translation of CPQ11–14 and the Parental-Caregiver Perceptions Questionnaire (P-CPQ), respectively, in this cross-sectional study. Children also provided a self-rating of oral health and were examined for dental caries. Exploratory Factor Analysis (EFA) was conducted to assess the dimensionality of the Hindi-CPQ11–14. Internal consistency and reliability on repeated administration were evaluated. Convergent and divergent validities were determined by estimating correlation coefficients between items and the hypothesised subscales. Concurrent validity was assessed using multiple linear regression analyses. The four factors extracted in EFA had a total variance of 38.5%, comprising 31 items. Cronbach’s alpha for the internal consistency of the overall scale was 0.90; reliability on repeated administration was 0.92. All the Hindi CPQ11–14 items had an item-hypothesised subscale correlation coefficient of ≥0.4, and these were greater than item-other hypothesised subscale correlations, demonstrating good convergent and divergent validities respectively. Hindi-CPQ11–14 was associated with self-ratings of the oral health and overall P-CPQ scores demonstrating good concurrent validity. Hindi-CPQ11–14 showed a factor structure different from the English CPQ11–14 and exhibited good validity and reliability.

Objective: To investigate the validity and reliability of a Chinese version of Spinal Cord Independence Measure III (SCIM III) in individuals with spinal cord injury. Design: Study on psychometric properties. Setting: An inpatient rehabilitation facility in China. Subjects: 102 participants with spinal cord injury. Mean (SD) age was 48.8 (15.6) years; tetraplegia/paraplegia ratio was 50/52; median time post injury was 2 months. Intervention: SCIM III was translated into Chinese. Chinese versions of Barthel Index and SCIM III were filled out for each participant by Rater 1. SCIM III was then administered by Rater 2 after 24 hours ( n = 67) and 7 days ( n = 65). Main Measures: Validity, inter-rater/test-retest reliability, and internal consistency of the Chinese version of SCIM III. Results: The total scores between the two raters were similar (mean ± SD: 33.8 ± 25.8 vs 33.8 ± 25.5, P = 0.95). Total agreement between the raters in each item was >80%, with both Pearson and intraclass correlation coefficients >0.97 ( P < 0.01) for each subscale and total score. The Pearson correlation coefficients of the two independent assessments performed by Rater 2 were also >0.97 ( P < 0.01) for each subscale and the total score. Cronbach α was >0.7 for each subscale and the total score for both raters. High consistency was found between Barthel Index and SCIM III total scores (Pearson correlation coefficient = 0.88, P < 0.01). Conclusion: The Chinese version of SCIM III is valid and reliable for the functional assessment of patients with SCI.

Background Functional magnetic resonance imaging (fMRI) is a popular method for examining pharmacological effects on the brain; however, the BOLD response is dependent on intact neurovascular coupling, and potentially modulated by a number of physiological factors. Pharmacological fMRI is therefore vulnerable to confounding effects of pharmacological probes on general physiology or neurovascular coupling. Controlling for such non-specific effects in pharmacological fMRI studies is therefore an important consideration, and there is an additional need for well-validated fMRI task paradigms that could be used to control for such effects, or for general testing purposes. Methods We have developed two variants of a standardized control task that are short (5 minutes duration) simple (for both the subject and experimenter), widely applicable, and yield a number of readouts in a spatially diverse set of brain networks. The tasks consist of four functionally discrete three-second trial types (plus additional null trials) and contain visual, auditory, motor and cognitive (eye-movements, and working memory tasks in the two task variants) stimuli. Performance of the tasks was assessed in a group of 15 subjects scanned on two separate occasions, with test-retest reliability explicitly assessed using intra-class correlation coefficients. Results Both tasks produced robust patterns of brain activation in the expected brain regions, and region of interest-derived reliability coefficients for the tasks were generally high, with four out of eight task conditions rated as ‘excellent’ or ‘good’, and only one out of eight rated as ‘poor’. Median values in the voxel-wise reliability measures were also >0.7 for all task conditions, and therefore classed as ‘excellent’ or ‘good’. The spatial concordance between the most highly activated voxels and those with the highest reliability coefficients was greater for the sensory (auditory, visual) conditions than the other (motor, cognitive) conditions. Discussion Either of the two task variants would be suitable for use as a control task in future pharmacological fMRI studies or for any other investigation where a short, reliable, basic task paradigm is required. Stimulus code is available online for re-use by the scientific community.

Force Data

The assessment of loading during walking and running has historically been limited to data collection in laboratory settings or with devices that require a computer connection. This study aims to determine if the loadsol®—a single sensor wireless insole—is a valid and reliable method of assessing force. Thirty (17 male and 13 female) recreationally active individuals were recruited for a two visit study where they walked (1.3 m/s) and ran (3.0 and 3.5 m/s) at a 0%, 10% incline, and 10% decline, with the visits approximately one week apart. Ground reaction force data was collected on an instrumented treadmill (1440 Hz) and with the loadsol® (100 Hz). Ten individuals completed the day 1 protocol with a newer 200 Hz loadsol®. Intraclass correlation coefficients (ICC3,k) were used to assess validity and reliability and Bland–Altman plots were generated to better understand loadsol® validity. Across conditions, the peak force ICCs ranged from 0.78 to 0.97, which increased to 0.84–0.99 with the 200 Hz insoles. Similarly, the loading rate ICCs improved from 0.61 to 0.97 to 0.80–0.96 and impulse improved from 0.61 to 0.97 to 0.90–0.97. The 200 Hz insoles may be needed for loading rate and impulse in running. For both walking and running, the loadsol® has excellent between-day reliability (>0.76).

The impact of deteriorating socio-economic conditions on breast-feeding duration in Jamaica is examined In spite of dramatic increases in the consumer price index for food and drink and consequently in the cost of artificial feeding, breast-feeding duration declined by 10.6% during 19871991. This was apparently due to a reduction in postpartum visits by district midwives. It is concluded that breast-feeding promotion should receive increased support under conditions of severe economic hardship.
