Validity and reliability study of the Turkish version of the self-efficacy for managing chronic disease 6-item scale

ABSTRACT: Background/aim:The measurement of self-efficacy is an important step toward improving chronic disease management, enhancing adherence to treatment, and assessing patients with chronic diseases. The purpose of this study was to assess the validity and reliability of the Turkish version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale. Materials and methods:In this methodological study, the sample consisted of 211 patients receiving chronic disease care in 2 family health centers in ?stanbul, Turkey. Data were analyzed with descriptive statistics, exploratory and confirmatory factor analyses, concurrent validity, Cronbach’s alpha, item-total correlation, and test-retest reliability. Results:Most of the sample were women (72%), primary school graduates (41.7%), hypertensive (68.7%), and had comorbidities (68.2%). The mean age of the sample was 60.5 ± 10.9. The scale mean was 5.66 ± 2.28. Cronbach’s alpha reliability was 0.90. Item-total correlations were between 0.64–0.85 and test-retest reliability was high (R = 0.95, P < 0.001). A positive, significant correlation was found in concurrent validity. According to the results of factor analysis, the scale had a 2-dimensional structure. Conclusion:The Turkish version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale is a valid and reliable instrument to assess perceived the self-efficacy level of patient with chronic disease.

Project description:OBJECTIVES:The aim of this study was to assess the reliability and validity of the Turkish version of the Individual-Level Abortion Stigma Scale. SETTING:Three hospitals affiliated to Public Hospitals Union General Secretariat in Manisa, a city located in Western Turkey. DESIGN:This was a methodological study. PARTICIPANTS:A total of 230 women aged 22-49 years who previously underwent abortion and volunteered to participate in the study. PRIMARY AND SECONDARY OUTCOME MEASURES:Data analysis was performed using the SPSS and LISREL software. The Content Validity Index was calculated based on the values obtained from expert opinions. In the reliability analysis, Cronbach's alpha values were calculated for the overall scale and its subscales. To test the stability of the scale over time, the scale was readministered to 30 women in the study 15 days later and the test-retest values (Pearson's correlation coefficients) were determined. In the validity analysis, the exploratory and confirmatory factor analyses were performed. In the exploratory factor analysis, the principal component analysis was performed using the varimax rotation and the factor loading of the scale was examined. Confirmatory factor analysis was performed to investigate the item-factor construct of the scale. RESULTS:The Content Validity Index was calculated as 0.86. The Cronbach's alpha values ranged between 0.83 and 0.94. The item-total correlation coefficients ranged between 0.36 and 0.72, and the test-retest reliability was 0.96 for the overall scale and its subscales (p<0.05). The total variance revealed by five factors was 75%. Confirmatory factor analysis of the scale revealed an acceptable compliance level (root mean square error of approximation=0.092, χ2/df=2.91, Goodness of Fit Index=0.831, Comparative Fit Index=0.928, p<0.001). CONCLUSIONS:The results suggest that this scale has the potential for use in research and clinical settings to measure abortion stigma among women.

Project description:To improve and support medication adherence among patients with chronic diseases, especially for long-term medication, it is important to consider both their relationship with healthcare providers and their lifestyle. We tested the reliability and validity of a modified 12-item Medication Adherence Scale.We revised a 14-item measure of medication adherence, created in 2009, to a more concise and clear 12-item version, and we verified the reliability and validity of the 12-item scale. We included 328 patients with chronic diseases participating in the Chronic Disease Self-Management Program in Japan from 2011 to 2014. Confirmatory factor analysis was used to assess whether the four factors assessed were the same as the previous 14-item Medication Adherence Scale. Cronbach's coefficient alpha was used to assess internal consistency reliability, and the relationships between patient demographic characteristics and medication adherence were compared with previous studies.The 12 items were categorized into the four factors "medication compliance", "collaboration with healthcare providers", "willingness to access and use information about medication", and "acceptance to take medication and how taking medication fits patient's lifestyle". Confirmatory factor analysis showed ?2/df?=?2.6, CFI?=?0.94, and RMSEA?=?0.069. Cronbach's alpha for the 12-item scale was 0.78. Cronbach's alpha for the four subscales was 0.74, 0.81, 0.67, and 0.45. Higher medication adherence was significantly associated with being a female patient, living with someone else, and age 40-49 years versus age 20-29 years. These relationships were the same as in previous studies.We modified our original 14-item scale to a 12-item Medication Adherence Scale for patients with chronic diseases, which considers their relationship with healthcare providers and lifestyle. Refinement might be needed because of the relatively low reliability of subscales. However, the modified scale is expected to contribute to more effective self-management of medication and to improving medication adherence, particularly among patients with chronic diseases who require long-term medication not only in Japan but also in other countries.

Project description:Background:With the rapid increase in ageing population, China is confronted with the daunting challenge of a growing number of patients with neurocognitive disorders (NCDs). This trend makes the maintenance of self-health and early intervention essential, highlighting the need for a tool that assesses self-efficacy of older adults in maintaining brain health or cognitive function. Aim:This study aimed to design the Brain Health Self-Efficacy Scale (BHSES) to measure elderly individuals' attitudes to NCDs, motivations and future plans for controlling risks. The psychometric properties of BHSES have been validated. Methods:Based on the current literature and relevant models, a 19-item scale was created during the first stage. A total of 660 older adults in the Yinhang community of Shanghai were included. The statistical approaches of item analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), criterion-related validity and reliability test were used to evaluate the quality of BHSES. In addition, the Geriatric Depression Scale (GDS) and the Self-Rating Anxiety Scale (SAS) were used as criteria to test the criterion-related validity. Results:To test item differentiation, the study adopted item analysis and excluded item 8. Selecting a random half of the sample for EFA, the BHSES was refined to 16 items, which were categorised into the following three dimensions: 'memory belief efficacy', 'self-care efficacy' and 'future planning efficacy'. These were highly consistent with the hypothesis model. Its cumulative variance contribution rate reached 61.14%, with factor loads of all items above 0.5. The three-factor model was confirmed by the remaining data through CFA. All fit indices reached the acceptable level (?2=3.045, Goodness of Fit Index=0.898, adjusted Goodness of Fit Index=0.863, Comparative Fit Index=0.916, Incremental Fit Index=0.917, Tucker-Lewis Index=0.900, root mean square error of approximation=0.079 and root mean residual=0.068). The GDS and SAS scores revealed significant correlations with the BHSES score, indicating a high criterion-related validity. The overall Cronbach's ? coefficient was 0.793, with the ? coefficients' distribution of subdimensions ranging from 0.748 to 0.883. Conclusions:The 16-item, self-compiled BHSES is a reliable and valid measurement. It could help identify older adults with potential risks for developing NCDs or with high suspicion of cognitive impairment onset in recent periods and also offer insight into tracking brain health self-efficacy in association with cognition status.
