Abstract Background: Focus on sleep regulation is crucial due to the direct health consequences of insufficient sleep to adolescents’ health and education performance. This study aims to develop and validate an instrument to measure sleep behavior self-regulation (SBSR) and its influential factors in a student sample.Methods: A preliminary version of the measurement instrument was developed using a literature review and conceptual framework. Expert analysis of content validity, item analysis, factor analysis and reliability analysis was performed for the psychometric evaluation. This study has a total of 401 students. The data was analyzed using SPSS 22.0 and AMOS 22.0.Results: The exploratory factor analyses offered a structure with six factors. The model presents a good fit (χ2/df = 1.65, RMSEA = 0.053, CFI = 0.920, and GFI =0.826). General test reliability was good (α = 0.9).Conclusions: SBSRI is a multidimensional instrument and a valid and reliable way of obtaining information about sleep behavior self-regulation. The use of this instrument will make it possible to adjust behavior to subjective goals and real experiences to promote sleep-related behavior change.

In the present study, a test was developed to measure the knowledge level of dairy farmers about scientific dairy farming. A preliminary set of 87 knowledge items was initially administered to 60 randomly selected dairy farmers for item analysis. The difficulty index and discrimination index was found out, and the items with difficulty index ranging from 30 to 80 and the discrimination index ranging from 0.30 to 0.55 were included in the final format of the knowledge test. A total of 48 items which fulfilled both the criteria were selected for the final format of knowledge test. Reliability of the test through split half method was found out to be 0.386 and the coefficient of correlation value by the test-retest method was 0.452, which was found to be significant at 1% level of significance. Hence, the knowledge test constructed was highly stable, reliable and validated for measuring what it intends to.

Parental Barriers

There is a plethora of literature on barriers to immunizations; however, these studies lack standardization of measurement. The aim of this study was to develop and establish an initial psychometric evaluation of an instrument to measure parental barriers to childhood immunizations. This was a cross-sectional study design. Data analysis included descriptive statistics, reliability estimates, item analysis, and factor analysis. Six hundred and fifty-five participants completed the survey. The Searching for Hardships and Obstacles to Shots instrument was developed with 60 items and reduced to 23 items thorough multiple statistical computations; the best factor model was a three-factor solution (Access to Shots, Concerns About Shots, and Importance of Shots) with a total variance explained of 59.4%. The Cronbach’s alpha reliability estimates ranged from .86 to .93, and temporal stability was adequate (r = .85). This study supports exceptional initial psychometric properties of an instrument to measure parental barriers to childhood immunizations.

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.

ABSTRACTBackground: Qualitative research has suggested that spousal carers of someone with dementia differ in terms of whether they perceive their relationship with that person as continuous with the premorbid relationship or as radically different, and that a perception of continuity may be associated with more person-centered care and the experience of fewer of the negative emotions associated with caring. The aim of the study was to develop and evaluate a quantitative measure of the extent to which spousal carers perceive the relationship to be continuous.Methods: An initial pool of 42 questionnaire items was generated on the basis of the qualitative research about relationship continuity. These were completed by 51 spousal carers and item analysis was used to reduce the pool to 23 items. The retained items, comprising five subscales, were then administered to a second sample of 84 spousal carers, and the questionnaire's reliability, discriminative power, and validity were evaluated.Results: The questionnaire showed good reliability: Cronbach's α for the full scale was 0.947, and test–retest reliability was 0.932. Ferguson's δ was 0.987, indicating good discriminative power. Evidence of construct validity was provided by predicted patterns of subscale correlations with the Closeness and Conflict Scale and the Marwit–Meuser Caregiver Grief Inventory.Conclusion: Initial psychometric evaluation of the measure was encouraging. The measure provides a quantitative means of investigating ideas from qualitative research about the role of relationship continuity in influencing how spousal carers provide care and how they react emotionally to their caring role.

The following study will present findings on the validity of the adaptation of the Burger and Cooper's Desirability of Control Scale into Spanish. Two samples are present: the first involving 1,999 people to study their psychometric properties. In the second sample, 111 people were included to estimate test/ retest reliability. Cultural adaptation was performed using the translation & back-translation method. Item analysis, internal consistency and test/re-test reliability were assessed, then evidence of the validity of the internal structure was determined by using exploratory and confirmatory factor analysis. Subject recruitment was performed to gather the 1,999 subjects stratified by age, gender quotas as designed in the sampling plan. Of the subjects, 51% were female, average age of 45 years old (SD = 17.5). All items from the original scale were understood correctly, while five items presented ceiling effect. Cronbach's alpha = .736 and a test-retest correlation r = .713 were obtained. The factor structure indicated the presence of four dimensions: forecast, autonomy, power and influence and reactance which were reassured in the confirmatory analysis (x2/df = 4.805, CFI =.932, TLI =.954, RMSEA = .062). The basic dimensions of the scale have shown to be stable and well-defined, though not perfect. The scope, possible applications of the scale and further research are later proposed and discussed.

Attitudes Toward War

A measure on attitudes toward war was administered to 125 student participants at a California university to assess psychometric properties for this scale for possible use in current research. A 5-point scale was substituted for the 2-point one originally. Item analysis indicated 23 of 32 items were viable. Using Cronbach reliability coefficient α and factor analysis, the shortened measure had an internal consistency reliability of .85. Factor analysis yielded a 4-factor structure: (1) War is Bad, (2) War is Necessary, (3) Positive Aspects of War, and (4) No Justification. These results indicate this seemingly outdated measure of war attitudes remains useful for current research purposes involving measuring attitudes toward war. However, longitudinal research is necessary.
