Three Components

The existing approaches to understanding the attraction and methods of its study are indicated. There are three levels of attraction in a small group — interpersonal, microgroup and group attraction, each of which includes three components — subjective, communicative and activity-oriented. In accordance with this idea a questionnaire of interpersonal attraction and a questionnaire of group and micro-group attraction were developed. Each of the questionnaires includes three subscales for measuring the relevant components of the attraction. To assess the validity and reliability of the questionnaires, a survey was conducted in 18 small production groups — primary structural divisions in organizations and in small companies. The total number of respondents was 200 employees. For each questionnaire factor analysis was performed and the internal consistency of the subscales was assessed. It is shown that the questionnaires have validity and reliability. It is proved expedient to separate three subscales in each questionnaire. The main conclusions are drawn and the possibilities of using the developed tools for research and practical purposes are highlighted.

Abstract Background The Lederman Prenatal Self-Evaluation Questionnaire (PSEQ) is used to assess psychosocial adaptation to pregnancy, labor, childbirth, and maternity. The PSEQ is a tool used in various countries and has been translated into Portuguese; however, it needs to be validated in Brazil. This study aimed to analyze the validity and reliability of the PSEQ in Brazilian pregnant women. Method This methodological validity study investigated internal consistency and reliability using Cronbach’s alpha and intraclass correlation coefficients. Construct validity was assessed using Pearson’s correlation between domains and confirmatory factor analysis. To assess concurrent validity, Pearson’s correlation between the different domains of the PSEQ and Prenatal Psychosocial Profile-Portuguese Version (PPP-VP) was determined. The level of significance was set at 5%. Results This study included 399 pregnant women in the northeastern region of Brazil. The internal consistency and reliability of the total PSEQ score were high (Cronbach's alpha = 0.89; intraclass correlation coefficient = 0.95). Validity analysis showed positive and significant correlations between all PSEQ domains, ranging from 0.14 to 0.56. Confirmatory factor analysis demonstrated the following values of goodness of fit: RMSEA = 0.05, SRMR = 0.08, CFI = 0.61, χ2/df = 1.77. The discriminant and concurrent validities of the PSEQ were confirmed. Conclusions The Portuguese version of the PSEQ has adequate psychometric properties and is a valid and reliable tool to evaluate psychosocial adaptation to pregnancy in Brazilian pregnant women.

AbstractObjectiveTo assess the validity of a locally adapted Household Food Insecurity Access Scale (HFIAS) in the measurement of household food insecurity (FI) in the city of Tehran.DesignA cross-sectional study.SettingUrban households were selected through a systematic cluster sampling method from six different districts of Tehran. The socio-economic status of households was evaluated using a questionnaire by means of interviews. An adapted HFIAS was used to measure FI. Content validity was assessed by an expert panel, and the questionnaire was then tested among ten households for clarity. Criterion validity was assessed by comparing the measure with a number of determinants and consequences of FI. Internal consistency was evaluated by Cronbach'sαand exploratory factor analysis. For repeatability, the questionnaire was administered twice to twenty-five households at an interval of 20 d and Pearson's correlation coefficient was calculated.SubjectsA total of 416 households.ResultsIn all, 11·8 %, 14·4 % and 17·5 % of the households were severely, moderately and mildly food insecure, respectively. Cronbach'sαwas 0·855. A significant correlation was observed between the two administrations of the questionnaire (r= 0·895,P< 0·001). Factor analysis of HFIAS items revealed two factors: the first five items as factor 1 (mild-to-moderate FI) and the last four as factor 2 (severe FI). Heads of food-secure households had higher education and higher job position compared with heads of food-insecure households (P< 0·001). Income and expenditure were lower in food-insecure households compared with food-secure households.ConclusionsAdapted HFIAS showed acceptable levels of internal consistency, criterion validity and reliability in assessing household FI among Tehranians.

Abstract Background Personal recovery is increasingly recognised as an important outcome measure in mental health services. This study aimed to develop a Japanese version of the Questionnaire about the Process of Recovery (QPR-J) and test its validity and reliability. Methods The study comprised two stages that employed the cross-sectional and prospective cohort designs, respectively. We translated the questionnaire using a standard translation/back-translation method. Convergent validity was examined by calculating Pearson’s correlation coefficients with scores on the Recovery Assessment Scale (RAS) and the Short-Form-8 Health Survey (SF-8). An exploratory factor analysis (EFA) was conducted to examine factorial validity. We used intraclass correlation and Cronbach’s alpha to examine the test-retest and internal consistency reliability of the QPR-J’s 22-item full scale, 17-item intrapersonal and 5-item interpersonal subscales. We conducted an EFA along with a confirmatory factor analysis (CFA). Results Data were obtained from 197 users of mental health services (mean age: 42.0 years; 61.9% female; 49.2% diagnosed with schizophrenia). The QPR-J showed adequate convergent validity, exhibiting significant, positive correlations with the RAS and SF-8 scores. The QPR-J’s full version, subscales, showed excellent test-retest and internal consistency reliability, with the exception of acceptable but relatively low internal consistency reliability for the interpersonal subscale. Based on the results of the CFA and EFA, we adopted the factor structure extracted from the original 2-factor model based on the present CFA. Conclusion The QPR-J is an adequately valid and reliable measure of the process of recovery among Japanese users with mental health services.

This study developed a measure of solidarity levels during pandemics, the Solidarity in Pandemics Scale (SPS). This was achieved using a study group of 842 individuals aged between 18 and 65 from different segments of society who had experienced the COVID-19 pandemic and differed in age, gender, and socioeconomic status. Exploratory factor analysis was used to establish the construct validity of the scale, producing a 15-item scale with a one-dimensional structure that explained 34.36% of the variance. Confirmatory factor analysis using a different study group revealed that all items have significant t-values, and the model established according to model fit indexes has meaningful and acceptable fit values. The internal consistency of the scale results was calculated using the Cronbach Alpha coefficient, and a reliability of .85 in terms of internal consistency was obtained. Test-retest reliability results as another indicator of reliability were found to be .85. Scores on the Altruism Scale were compared with those on the SPS to evaluate the scale’s criterion validity, and a significant relationship was found between the two scale scores. This analysis indicates that the Solidarity in Pandemics Scale is a valid and reliable psychometric tool.

Background: Sensory integration is a necessary skill for acquiring reading skills because it strongly depends on the rapid and strong relation between written and verbal symbols. There is no standardized test for Iranian children with dyslexia to investigate their sensory processing problems. Therefore, understanding the validity and reliability of the child sensory profile 2 (CSP2) would be essential for a detailed assessment of sensory impairments in dyslexic children. Objectives: The current research aimed to establish the internal consistency, factor analysis, and convergent validity of the Persian version of CSP2 in children with dyslexia. Methods: The sample of this study included 200 dyslexic children aged 6 to 12 years who were referred to learning disabilities centers in Qom from September 2019 to February 2020 by using the multistage sampling method. To collect data, the CSP2 questionnaire and the dyslexia test (NEMA) were used. The factor structure was assessed by confirmatory factor analysis. The internal consistency of the CSP2 was examined by using Cronbach’s alpha. Convergent validity was assessed by examining the relationship between CSP2 and NEMA. Results: Internal consistency was obtained as 0.89, 0.92, 0.77, and 0.94 for the four subscales of sensory processing, namely registration, seeking, sensitivity, and avoiding, respectively. The result of confirmatory factor analysis gained support for Dunn's four-factor model. Total scores of NEMA were correlated with the scores of CSP2 subscales (seeking, avoiding, sensitivity, and registration). Conclusions: The Persian version of the Child Sensory Profile 2 is a valid (via confirmatory factor analysis and convergent validity) and reliable (via internal consistency) tool for assessing sensory processing in children with dyslexia.

The goal of this study is to develop a Guidance Qualification Scale for Preschool Teachers and examine the validity and reliability of the scale. The research was conducted with 374 teachers working in preschools in Istanbul and they were chosen by the random sampling method. Factor analysis was carried out for the construct validity of the scale. Internal consistency coefficients and test-retest reliabilities were examined and item analysis was performed for reliability studies. As a result of the factor analysis, 59 items which explained 55,989% of the total variance (Total Variance Explained 45,050%), were obtained under four factors. When the factor weights of the scale are examined, items were found to have weight values ranging from .746 to .453. Cronbach’s Alpha internal consistency coefficients of the “Preschool Teacher’s Guidance Qualifications Scale” were found to be .977 for the total scale, .954 for the "Supporting Educational Development and Interpersonal Relationships" sub-dimension, .943 for the "Supporting Individual Development and Orientation" sub-dimension, .904 for the "Self-acceptance, Support for Self and Social Development" sub-dimension and .909 for the "Recognizing Individuals, Identifying Problems and Supporting Parents" sub-dimension. Also, the test-retest reliability study of the scale was conducted with 44 teachers. According to the results of the t-test applied for differences between the average item scores of upper 27% and lower 27% groups of items on (in?) the scale, all differences were found to be significantly in favor of the upper 27% group. In light of these findings, it can be said that the “Preschool Teacher’s Guidance Qualifications Scale” can be used as a valid and reliable measurement tool in the field of education.
