Purpose: The purpose of this study is to translate the Perceived Therapeutic Efficacy Scale (PTES) into Korean and investigate its validity and reliability. Methods: The authors conducted a cross-sectional survey using baseline data from a randomized controlled study to psychometrically validate the PTES-Korean (PTES-K) among 108 adults with type 2 diabetes from an outpatient clinic at a university-affiliated hospital in Korea. The original PTES was forward-translated and back-translated to ensure translation equivalence of the PTES-K. Structured questionnaires were used for psychometric evaluation; exploratory and confirmatory factor analysis assessed validity, and Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were used for reliability. Results: The interitem correlation analyses revealed that 5 items were redundant; thus, the scale was reduced to 5 items. A 1-factor model explained 76.85% of the variance; confirmatory factor analysis showed that this model adequately fit the data. The ICC for test-retest reliability was .78; Cronbach’s alpha was .92. The PTES-K showed significant associations with the scores of diabetes self-care activities for physical activity, quality of life, and depressive symptoms. Participants with good glycemic control and regular physical activity tended to have a higher score on the PTES-K than their counterparts, demonstrating known-groups validity. Conclusions: The cross-cultural applicability, reliability, and validity of the PTES-K were confirmed. The PTES-K may be used in clinical settings to examine the potential role of perceived therapeutic efficacy for physical activity in enhanced glycemic control among patients with diabetes.

Objectives: This study aims to adapt the Lymphedema Symptom Intensity and Distress Survey- Arm (LSIDS-Arm) into Turkish and to test its validity and reliability. Patients and methods: Between September 2017 and July 2018, this descriptive, methodological study included a total of 186 women (mean age: 55.4±10.2 years; range, 20 to 80 years) who were diagnosed with breast cancer-related lymphedema (BCRL) and followed in the lymphedema outpatient clinic. Data were collected using sociodemographic and clinical features form, LSIDS-Arm, and Functional Assessment of Cancer Treatment-Breast Cancer Scale+4 (FACT-B+4). After the linguistic and content validity of the scale was achieved, confirmatory factor analysis and known-groups validation were utilized to test the construct validity. Reliability of the survey was tested using the Cronbach alpha and Spearman Brown coefficient, item analysis, and parallel forms reliability. Results: All patients completed the questionnaire. After achievement of linguistic and content validity, confirmatory factor analysis results were found to be higher than the accepted value. Known-groups validation revealed a significant difference in the mean scores for the intensity and distress scales between the patients with and without lymphedema. Cronbach alpha for the subscales ranged from 0.61 to 0.86. Parallel forms reliability showed a moderate, significant correlation between subscales of the intensity and distress scales of the survey and the subscales of FACT-B+4. Conclusion: The Turkish version of the survey is valid and reliable and can be used to evaluate symptoms, severity of symptoms, and distress caused by BCRL symptoms in the Turkish women.

The aim of this study is to develop a scale appropriate for the cultural structure that can be used to measure social media addiction in adolescents. For the scale development process, 67 items were created first and a draft form was obtained following the results of pilot scheme and expert opinions. The validity and reliability studies of the scale were conducted with a total of 830 students, 446 male and 384 female students studying in different secondary schools (7th and 8th grades) and high schools in Amasya during the academic year of 2017-2018. Exploratory factor analysis and confirmatory factor analysis were performed for the validity analysis of the scale. As a result of the exploratory factor analysis, a scale consisting of 24 items and 2 sub-dimensions explaining 51,405% of the total variance was obtained. Confirmatory factor analysis was performed after that and the fit indices were found to be adequate and the two-factor scale was confirmed (x2 /sd=1.89; GFI= .90; CFI = .93; TLI= .92; RMSEA = .052 and SRMR= 0,047).In addition, in order to determine the validity of the scale, its relationship with Bayraktar's (2001) "Internet Dependency Scale" and was evaluated and a significant positive relationship between them was found. The Cronbach Alpha reliability coefficient for the subscales and total of the scale was calculated and found to be sufficient (Cronbach α=between .86 and .93). In addition to this, to determine the test-retest reliability, the scale was applied to the same group for three weeks and the correlation coefficients were found significant. As a result, the values obtained indicate that Social Media Addiction Scale is a valid and reliable scale to measure social media addiction of adolescents in Turkey.Extended English summary is in the end of Full Text PDF (TURKISH) file.ÖzetBu çalışmanın amacı, ergenlerdeki sosyal medya bağımlılığını ölçmede kullanılabilecek kültürel yapıya uygun bir ölçek geliştirmektir.

Abstract. The present research aimed at examining measurement invariance of the Serbian version of the Satisfaction with Life Scale (SWLS) across age, gender, and time. A total sample in Study 1 consisted of 2,595 participants from Serbia, with a mean age of 23.79 years (age range: 14–55 years). The final sample in Study 2 included 333 Serbian undergraduate students ( Mage = 20.81; age range: 20–27 years), who completed the SWLS over periods of 6 and 18 months after the initial assessment. Confirmatory factor analysis (CFA) supported the modified unidimensional model of the SWLS, with correlated residuals of items 4 and 5 tapping past satisfaction. The results of the multigroup confirmatory factor analysis supported the full scalar invariance across gender and over time and partial scalar invariance across age. Latent mean comparisons revealed that women reported higher life satisfaction than men. Additionally, adolescents reported higher life satisfaction than students and adults, with adults showing the lowest life satisfaction. Our findings indicate that the SWLS allows meaningful comparisons in life satisfaction across age, gender, and over time.

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.

Composite Reliability

Composite reliability, or coefficient omega, can be estimated using structural equation modeling. Composite reliability is usually estimated under the basic independent clusters model of confirmatory factor analysis (ICM-CFA). However, due to the existence of cross-loadings, the model fit of the exploratory structural equation model (ESEM) is often found to be substantially better than that of ICM-CFA. The present study first illustrated the method used to estimate composite reliability under ESEM and then compared the difference between ESEM and ICM-CFA in terms of composite reliability estimation under various indicators per factor, target factor loadings, cross-loadings, and sample sizes. The results showed no apparent difference in using ESEM or ICM-CFA for estimating composite reliability, and the rotation type did not affect the composite reliability estimates generated by ESEM. An empirical example was given as further proof of the results of the simulation studies. Based on the present study, we suggest that if the model fit of ESEM (regardless of the utilized rotation criteria) is acceptable but that of ICM-CFA is not, the composite reliability estimates based on the above two models should be similar. If the target factor loadings are relatively small, researchers should increase the number of indicators per factor or increase the sample size.

Background: Child obesity is one of the main health problems all across the world, which leads to mental and physical health problems. Various models are used in designing intervention to prevent child obesity, one of which is social-cognitive theory (SCT). The constructs of social-cognitive theory are commonly used for designing preventive interventions. However, there is no specific tool based on the constructs of social-cognitive theory to assess the factors associated with child obesity. Aim: The aim of this study was to investigate the validity and confirmatory factor analysis of a SCT-based questionnaire for assessing obesity preventing behaviors among 4-6 years old children. Method: A cross-sectional study was first conducted in 2016 on 240 preschool children aged 4-6 years in Behbahan city (a city in southwest Iran) to assess the obesity prevention behaviors among them using a SCT-based questionnaire. To investigate the validity and confirmatory factor analysis of the SCT-based questionnaire, content and face validity as well as forward-backward translation method were used. Reliability of the questionnaire was also measured by Cronbach’s alpha coefficient and Intra-class Correlation Coefficient (ICC). Construct validity was assured by confirmatory factor analysis. To measure the obesity prevention behaviors in 4-6 years old children, the construct of SCT, including environment, emotional coping, outcome expectations, goal setting and self-efficacy were used. Also, the obesity prevention behaviors used in the model included physical activity, consumption of fruit and vegetable, consumption of sugar-free drinks, and screen. Results: Results of this study confirmed the acceptable content and face validity of the SCT-based questionnaire. The results of confirmatory factor analysis also confirmed the factor loading of more than 0.3 for all variables; therefore, the SCT-based questionnaire had an acceptable validity and reliability. Conclusions: Since the SCT-based questionnaire had an acceptable validity and reliability, it can be used to assess the obesity prevention behaviors in 4-6 year old children, and also to design relevant educational interventions.

Purpose The brand equity pyramid is a theory that explains how people develop loyalty and an attachment to a brand. The purpose of this study is to test whether the predictions made by the theory hold when applied to the brand of ParticipACTION, a Canadian non-profit organization that promotes active living. A secondary objective was to test whether this theory predicted intentions to be more physically active. Design/methodology/approach A research agency conducted a cross-sectional, online brand health survey on behalf of ParticipACTION. Exploratory factor analysis and confirmatory factor analysis established the factor structure. Structural equation modeling was used to test the hypothesized model. Findings A nationally representative sample of Canadian adults (N = 1,191) completed the survey. Exploratory factor analysis and confirmatory factor analysis supported a hypothesized five-factor brand equity framework (i.e. brand identity, brand meaning, brand responses, brand resonance and intentions). A series of structural equation models also provided support for the hypothesized relationships between the variables. Practical implications Though preliminary, the results provide a guide for understanding the branding process in the activity-promotion context. The constructs identified as being influential in this process can be targeted by activity-promotion organizations to improve brand strength. A strong organizational brand could augment activity-promotion interventions. A strong brand may also help the organization better compete against other brands promoting messages that are antithetical to their own. Originality/value This is the first study to test the brand equity pyramid using an activity-promotion brand. Results demonstrate that the brand equity pyramid may be useful in this context.
