Cross-cultural translation and psychometric properties of the Persian version Manchester respiratory activities of daily living questionnaire (MRADLQ-P).

PURPOSE: The present study was an attempt to investigate cross-cultural adaptability and evaluate the psychometric properties of the Persian version of the Manchester respiratory activities of daily living questionnaire ((MRADLQ-P). PATIENTS AND METHODS: In a cross-sectional study, we selected 260 patients with severe respiratory diseases who needed to be admitted to the respiratory wards of this city hospital. The process of cultural localization of the questionnaire was performed based on a standard and valid process. Psychometric properties of the instrument were confirmed based on face and content validity assessments, convergent validity, discriminative validity and internal consistency. Data collected by demographic questionnaire, MRADL questionnaire and work ability index. Data were analyzed by SPSS 22 using descriptive statistics (mean and standard deviation), Spearman correlation coefficient, Cronbach's alpha coefficient, and Mann-Whitney test. RESULTS: The mean age of participants was 48.8 ± 20.1 years. 176 (71.5%) were male. face content validity including content validity index (CVI) was 0.82 and content validity ratio and it was good. The questionnaire was measured at the same time as the work ability index, which Mann-Whitney test showed that the questionnaire has good differential power. Cronbach's alpha coefficient of 0.9 indicates a very good reliability of the questionnaire. CONCLUSION: The results show that intercultural psychometrics of MRADL questionnaire has good validity, reliability, and differential power that can be a good tool for use in future studies. Also, the translation of this checklist included translation into the target language, backward translation of the Persian versions into the original language, and comparisons and ambiguities to obtain a final and acceptable version.

Internet Addiction Effect on Quality of Life: A Systematic Review and Meta-Analysis.

PURPOSE: Due to the use of different methodologies, tools, and measurements, the positive or negative impact of Internet use on human life quality is accompanied by a series of ambiguities and uncertainties. Therefore, in this study, a systematic review and meta-analysis are conducted regarding the effect of Internet addiction on the quality of life. METHODS: A systematic search of resources was conducted to investigate the effect of Internet addiction on the quality of life. The databases of PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Science Direct were searched from January 1980 to July 2020. The articles were screened by two researchers in multiple levels in terms of the title, abstract, and full-text; then, final studies that met the inclusion criteria were retrieved and included in the study. RESULTS: After searching the previously mentioned international databases, 3863 papers were found, 18 of which we included in the final analysis. Surveys indicated that people who had a high Internet addiction received lower scores of quality of life than those who were normal Internet users (OR = 2.45, 95% CI; 2.31-2.61, p < 0.001; I 2 = 85.23%, p < 0.001). Furthermore, There was a negative significant relationship between Internet addiction and quality of life in the psychological (OR = 0.56, 95% CI: 0.32-0.99, p=0.04, I 2 = 97.47%, p < 0.001), physical (OR = 0.58, 95% CI: 0.39-0.86, p=0.007, I 2 = 95.29%, p=0.001), and overall quality of life score (OR = 0.39, 95% CI: 0.27-0.55, p < 0.001, I 2 = 0.0%, p=0.746). CONCLUSION: These findings illustrate that Internet addiction should be regarded as a major health concern and incorporated into health education and intervention initiatives.

Development and validation of dust exposure prevention questionnaire for cardiovascular patients based on the health belief model.

BACKGROUND: Many cardiovascular patients suffer from respiratory failure. Environmental conditions can exacerbate symptomatology. It is necessary to prevent exposure to dust by taking educational steps to identify and modify patient behavior. This study aimed to develop and validate a dust exposure behavior questionnaire based on the Health Belief Model. METHODS: A mixture of qualitative and quantitative methods was employed to design and develop the desired tool. Qualitative methods were used to identify the preventive behaviors needed by cardiovascular patients at risk of dust exposure using the opinions of two expert panels and a literature review. The quantitative phase of the research was performed to evaluate the psychometric properties of the research tool. The research population comprised 417 people with cardiovascular disease referred to a heart hospital in Bushehr, Iran in 2018. Consenting participants entered the study through consecutive sampling. RESULTS: The final version of the questionnaire included 27 items across six domains, namely perceived susceptibility, perceived barriers, perceived severity, perceived benefits, cues to action, and self-efficacy. The mean values of the content validity ratio and content validity index were 0.93 and 0.9, respectively. In addition, all items had a good correlation with the total score of their parent domain (P < 0.01). The model fit was initially unsuitable, according to the related indices. Hence, to achieve a better model fit, the model was improved by releasing some parameters based on the modifications suggested by the AMOS software. The modified model featured an acceptable fit (χ2/df = 2.2, P < 0.001). Cronbach's alpha coefficients also confirmed appropriate reliability for all six domains. CONCLUSION: The Dust Exposure Prevention questionnaire has desirable psychometric properties and appropriate validity to determine the behavioral factors involved in harm from dust exposure among cardiovascular disease patients. This marks an effective step toward evaluating the factors effective in preventing complications related to dust exposure among such patients.
