The purpose of this study is to create a new tool capable of diagnosing the severity of internet addiction (IA) and is based on the nine IGD criteria. These same criteria were suggested by the APA in the last edition of the DSM-51. A sample was recruited with a method of convenience and 300+ participants were recruited through different forums and social networks. The construct validity of the IDS9SF test was achieved through factor analysis and nomological validity. The concurrent validity, criterion and reliability of the test itself have been thoroughly investigated through the most common and consolidated data analysis techniques, confirming that the same test has sufficient psychometric properties to be used also in the Italian territory. Furthermore it is necessary to remember that this preliminary research is only valid in the field of data and statistics with all the limitations of the case and cannot be used for a real clinical evaluation.

This study evaluated the psychometric properties of the Brazilian version of the Personality Belief Questionnaire – Short Form (PBQ-SF). A sample of 700 college students answered to the Brazilian version of the PBQ-SF. The results showed good estimates of reliability (Cronbach’s alpha) of the PBQ-SF scales, indicating a significant association between the beliefs of each of the scales. The results of factor analysis of the PBQ-SF were similar to its original version. Overall, the findings provide support for the existence of factorial validity for the Brazilian version of the PBQ-SF, suggesting that it is a practical tool for the measurement of dysfunctional beliefs related to personality disorders

Abstract Objectives Existing measures of inflammatory bowel disease (IBD) symptoms are not well suited to self-report, inadequate in measurement properties, insufficiently specific, or burdensome for brief or repeated administration. We aimed to develop a patient-reported outcome measure to assess a broader range of IBD symptoms. Methods The IBD Symptoms Inventory (IBDSI) was developed by adapting symptom items from existing clinician-rated or diary-format inventories; after factor analysis, 38 items were retained on 5 subscales: bowel symptoms, abdominal discomfort, fatigue, bowel complications, and systemic complications. Participants completed the IBDSI and other self-report measures during a clinic visit. A nurse administered the Harvey Bradshaw Index (HBI) for Crohn’s disease (CD) or the Powell-Tuck Index (PTI) for ulcerative colitis (UC), and a gastroenterologist completed a global assessment of disease severity (PGA). Results The 267 participants with CD (n = 142) or UC (n = 125), ages 18 to 81 (M = 43.4, SD = 14.6) were 58.1% female, with a mean disease duration of 13.9 (SD = 10.5) years. Confirmatory factor analysis supported the 5 subscales. The total scale and subscales showed good reliability and significant correlations with self-report symptom and IBD quality of life measures, the HBI, PTI, and PGA. Conclusions The IBDSI showed strong measurement properties: a supported factor structure, very good internal consistency, convergent validity, and excellent sensitivity and specificity to clinician-rated active disease. Self-report HBI and PTI items, when extracted from this measure, produced scores comparable to clinician-administered versions. The 38-item IBDSI, or 26-item short form, can be used as a brief survey of common IBD symptoms in clinic or research settings.

The purpose of this study was to evaluate the validity and reliability of the Turkish version of the Diabetic Foot Scale–Short Form (DFS-SF). The study was cross-sectional and conducted between January and October 2019 in a diabetic foot council of a university hospital. A total of 194 diabetic foot patients participated in the study. A Patient Identification Form and DFS-SF were used for data collection. Forward and backward translations were used in language validity. Expert opinions were obtained to determine the Content Validity Index. To determine construct validity, exploratory factor analysis and confirmatory factor analysis were used. Cronbach’s α internal consistency coefficient, item-scale correlation, and test-retest reliability were used to evaluate reliability. It was found that Content Validity Index was 0.97 (0.86-1.00), the factor loading of scale varied from 0.378 to 0.982, Cronbach’s α value varied from 0.81 to 0.94, and item-total correlations were between 0.30 and 0.75. The Turkish version of the DFS-SF was found valid and reliable to measure the quality of life of diabetic foot patients.

Economic Coercion

Assessing progress toward Sustainable Development Goal (SDG) 5, to achieve gender equality and to empower women, requires monitoring trends in intimate partner violence (IPV). Current measures of IPV may miss women’s experiences of economic coercion, or interference with the acquisition, use, and maintenance of financial resources. This sequential, mixed-methods study developed and validated a scale for economic coercion in married women in rural Bangladesh, where women’s expanding economic opportunities may elevate the risks of economic coercion and other IPV. Forty items capturing lifetime and prior-year economic coercion were adapted from formative qualitative research and prior scales and administered to a probability sample of 930 married women 16–49 years. An economic coercion scale (ECS) was validated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) with primary data from random-split samples ( N1 = 310; N2 = 620). Item response theory (IRT) methods gauged the measurement precision of items and scales over the range of the economic-coercion latent trait. Multiple-group factor analysis assessed measurement invariance of the economic-coercion construct. Two-thirds (62.26%) of women reported any lifetime economic coercion. EFA suggested a 36-item, two-factor model capturing barriers to acquire and to use or maintain economic resources. CFA, multiple group factor analysis, and multidimensional IRT methods confirmed that this model provided a reasonable fit to the data. IRT analysis showed that each dimension provided most precision over the higher range of the economic coercion trait. The Economic Coercion Scale 36 (ECS-36) should be validated elsewhere and over time. It may be added to violence-specific surveys and evaluations of violence-prevention and economic-empowerment programs that have a primary interest measuring economic coercion. Short-form versions of the ECS may be developed for multipurpose surveys and program monitoring.

Abstract Background The short form of the Stroke Impact Scale (SF-SIS) consists of eight questions and provides an overall index of health-related quality of life after stroke. The goal of the study was the evaluation of construct validity, reliability and responsiveness of the SF-SIS for the use in German-speaking stroke patients in rehabilitation. Methods The SF-SIS, the Stroke Impact Scale 2.0 (SIS 2.0), EQ-5D-5L, National Institutes of Health Stroke Scale (NIHSS) and de Morton Mobility Index were assessed in 150 inpatients after stroke, with a second measurement two weeks later for the analyses of responsiveness. In 55 participants, the test–retest-reliability was assessed one week after the first measurement. The study was designed following the recommendations of the COSMIN initiative. Results The correlations of the SF-SIS with the SIS 2.0 (ρ = 0.90), as well as the EQ-5D-5L (ρ = 0.79) were high, as expected. There was adequate discriminatory ability of the SF-SIS index between patients who were less and more severely affected by stroke, as assessed by the NIHSS. Exploratory factor analysis indicated a two-factor structure of the SF-SIS explaining 59.9% of the total variance, providing better model fit in the confirmatory factor analysis than the one-factorial structure. Analyses of test–retest-reliability showed an intraclass correlation coefficient of 0.88 (95% CI 0.75–0.94). Hypotheses concerning responsiveness were not confirmed due to lower correlations between the assessments change scores. Conclusion Results of this analysis of the SF-SIS’s psychometric properties are matching with the validity analysis of the English original version, confirming the high correlations with the Stroke Impact Scale and the EQ-5D-5L. Examination of structural validity did not confirm the presumed unidimensionality of the scale and found evidence of an underlying two-factor solution with a physical and cognitive domain. Sufficient test–retest reliability and internal consistency were found. In addition, this study provides first results for the responsiveness of the German version. Trial registration The study was registered at the German Clinical Trials Register. Trial registration number: DRKS00011933, date of registration: 07.04.2017

ABSTRACT Objectives: Although wisdom is a desirable life span developmental goal, researchers have often lacked brief and reliable construct measures. We examined whether an abbreviated set of items could be empirically derived from the popular 40-item five-factor Self-Assessed Wisdom Scale (SAWS). Design: Survey data from 709 respondents were randomly split into two and analyzed using confirmatory factor analysis (CFA). Setting: The survey was conducted online in Australia. Participants: The total sample consisted of 709 participants (M age = 35.67 years; age range = 15–92 years) of whom 22% were male, and 78% female. Measurement: The study analyzed the 40-item SAWS. Results: Sample 1 showed the traditional five-factor structure for the 40-item SAWS did not fit the data. Exploratory factor analysis (EFA) on Sample 2 offered an alternative model based on a 15-item, five-factor solution with the latent variables Reminiscence/Reflection, Humor, Emotional Regulation, Experience, and Openness. This model, which replicates the factor structure of the original 40-item SAWS with a short form of 15 items, was then confirmed on Sample 1 using a CFA that produced acceptable fit and measurement invariance across age groups. Conclusions: We suggest the abbreviated SAWS-15 can be useful as a measure of individual differences in wisdom, and we highlight areas for future research.

Burden Scale

Caregiver burden describes the physical, psychological, social, and financial demands of providing care to others. Caregiver burden has been investigated in general, and off-time caregiving often specific to chronic, recurring conditions. Despite the substantial research attention to caregiving burden, there have been few studies aimed establishing the psychometric evaluation of measurement tools used to measure the construct ( Pendergrass et al., 2018 ). Accurate measurement of caregiving burden is essential for studying the myriad effects on caregivers’ mental, physical, financial, and relational health. To begin to fill this gap, we conducted an exploratory factor analysis and a confirmatory factor analysis of the Burden Scale for Family Caregivers ( Pendergrass et al., 2018 ) in two distinct samples. Results of an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) indicated a one factor solution. Implications for these findings on the study of caregiver burden are included.

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.
