Farsi Translation and Cultural Adaptation of Psychosocial Impact of Dental Esthetics Questionnaire and Evaluation of its Validity and Reproducibility

AIMS: This study aimed to translate the psychosocial impact of dental esthetics questionnaire (PIDAQ) to Farsi and assess its cultural adaptation, validity, and reproducibility. MATERIALS AND METHODS: The PIDAQ was translated to Farsi by experts fluent in Farsi and English. It was then back-translated to English by another expert blinded to the original version. The translated version was administered among 40 patients to assess its face validity and content validity. Final version of the questionnaire along with the index of orthodontic treatment need (IOTN) and the perception of occlusion scale (POS) was administered among 400 patients (224 females, 176 males) to assess their need for orthodontic treatment. To assess its validity, the mean score of PIDAQ was evaluated in different ranges of IOTN-esthetic component (IOTN-AC), IOTN-dental health component (DHC), and POS. To assess its convergent validity, the PIDAQ, IOTN-AC, IOTN-DHC, and POS scores were evaluated. Its construct validity was evaluated by confirmatory and exploratory factor analysis. Its internal consistency was evaluated using Cronbach’s alpha and the split-half method. Its test-retest reliability was evaluated by calculating the intraclass correlation coefficient (ICC). RESULTS: The Cronbach’s alpha was found to be 0.900–0.945 for the questionnaire domains, which showed good reliability. The ICC for the four questionnaire domains was 0.926, which was excellent. IOTN-DHC, IOTN-AC, and POS had significant correlations with the questionnaire domains. CONCLUSIONS: The Farsi version of PIDAQ has optimal validity and reliability and can be used for assessment of the dental esthetics-related quality of life of Iranian young adults.

Abstract Background Population aging is an important phenomenon for many countries worldwide. Considering the growing trend of aging population in Iran, it is very important to consider beliefs and perceptions of old people about aging. The Aging Perception Questionnaire (APQ) is one of the most common instruments that used to measure aging comprehension. The present study was a methodological inquiry that aimed to examine validity and reliability of the Persian version of the Aging Perception Questionnaire (APQ). Methods Forward-backward procedure was used for translation. Content validity and face validity were evaluated qualitatively. In order to evaluate construct validity a cross section study was conducted and both exploratory and confirmatory factor analyses were performed. In order to determine reliability, internal consistency (the Cronbach’s alpha) and stability (Intraclass Correlation Coefficient -ICC) were estimated. Results A total of 500 elderly people attending the community centers in Tehran, Iran were entered in other study and completed the Persian version of the questionnaire. Most elderly were female (52.8%).The mean age of participants was 68.33 (SD ± 6.10) years. The results obtained from exploratory factor analysis showed a four-factors solution (consequences negative, emotional representation, control positive and consequences positive) that jointly explained 52.8% of the total variance observed. In addition the confirmatory factory analysis showed a good fit for the data. Finally, the Cronbach’s alpha coefficient of 0.83 ranging from 0.80 to 0.87 was obtained for the whole scale and the subscales. The ICC value of 0.96 ranging from 0.90 to 0.98 was found for the whole scale and the subscales. Conclusion The results indicated that the Persian version of APQ is valid and can be used to measure aging perception in Iran.

Purpose. Pain is one of the nonmotor symptoms of Parkinson’s disease (PD) that, in order to be better managed, requires to be evaluated. Evaluations are done using pain assessment scales such as the Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2). The goal of this study was to assess the psychometric properties of SF-MPQ-2 to measure pain in people with PD. Methods. Four hundred and twenty-eight PD patients with a mean (SD) age of 60.11 (11.44) years were included. Accessibility was measured through floor and ceiling effects. Dimensionality was estimated by exploratory factor analysis. The association between SF-MPQ-2 and other scales such as Neuropathic Pain Symptom Inventory, Douleur Neuropathic 4, Brief Pain Inventory, King’s Pain Parkinson’s Disease Scale, and Visual Analog Scale-Pain was considered to calculate convergent validity. Internal consistency and test-retest reliability were assessed by Cronbach’s alpha and intraclass correlation coefficient (ICC), respectively. Results. A noticeable floor effect was found. Dimensionality results indicated four factors for this scale. A strong relationship was found between the SF-MPQ-2 total score and other scales (r = 0.55 to 0.85). In reliability analysis, Cronbach’s alpha and ICC were 0.93 and 0.94 for SF-MPQ-2, respectively. Conclusion. The results of this study showed that SF-MPQ-2 has adequate validity and reliability to measure pain in people with Parkinson’s disease.

Heart Failure Questionnaire

The Minnesota Living with Heart Failure Questionnaire (MLHFQ) has been developed to measure health-related quality of life (HRQoL) status of Heart Failure (HF) patients. The aim of this study was to translate MLHFQ into the Persian version and assess the validity and reliability of the translated version. We used a forward-backward procedure for translation. In a cross-sectional study, 105 HF patients and 50 healthy subjects were selected to assess the reliability and construct validity of the instrument. The face and content validity were used to assess the questionnaire validity. Validity was examined on the HF patients group, using the Persian version of the Short form-36 health survey (SF-36) Questionnaire. In order to assess the questionnaire’s reliability, the Intraclass correlation coefficient (ICC) and Cronbach’s alpha were calculated. Test-retest reliability was examined by re-administering the MLHFQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all 2 domains were higher than 0.91, P≤0.000). Internal consistency for Physical domain (PD), emotional domain (ED) and total scores using Cronbach’s alpha were 0.90, 0.84 and 0.92, respectively. ICC for PD, ED and total scores were 0.95, 0.94, and 0.97, respectively. Good and very good Pearson's Correlation Coefficient was seen between MLHFQ and SF-36 (r= -0.47 to -0.775, P≤0.000 for PD; r= -0.47 to -0.65, P≤0.000 for ED). The Persian version of the MLHFQ had satisfactory reliability and validity for assessing HRQoL status of Iranian HF patients. © 2019 Tehran University of Medical Sciences. All rights reserved.

Abstract Background: Occupational back pain is the most prevalent health problem among nurses and needs to be assessed by a valid and multi-factorial questionnaire. The purpose of the present study was to design and develop an instrument based on the PRECEDE-PROCEED model for assessing job-related behaviors that cause low back pain. Methods: First an item pool of 49 items was generated. Then, content and face validity was carried out. Consequently, a cross-sectional study was conducted in Mazandaran, Iran. The questionnaire was distributed among a sample of nurses working in hospitals affiliated to Mazandaran University of Medical Sciences. Exploratory factor analysis was used to determine the factor structure of the questionnaire. The Cronbach’s alpha was estimated to assess the reliability and the intraclass correlation coefficient was calculated to examine stability. Results: In all 155 nurses participated in the study. The mean age of respondents was 34.1 (SD = 7.66) years, and 83.2% were female. Six factors with 30 items emerged from the exploratory factor analysis: knowledge, attitude, self-efficacy, reinforcing factors, enabling factors and behavior that jointly accounted for %66.5 of behavior change variance observed. The Cronbach’s alpha coefficient showed excellent internal consistency (alpha=0.92). The intraclass correlation coefficient with 2-weeks interval also indicated that the questionnaire has satisfactory stability (ICC = 0.97). Conclusions: The findings showed that the Occupational Back Pain Prevention Behavior Questionnaire is a reliable and valid instrument for measuring occupational back pain and prevention behaviors among nurses.

Background: Nursing shortages are a significant problem experienced by medical institutions worldwide as well as Indonesia. Understanding nurses’ work environment is a proper strategy for enhancing the retention and overcoming shortages of nurses. The Quality Nursing Work Environment (QNWE) is a well-known tool that has been commonly used to evaluate the working atmosphere of nurses. However, the availability and validated version of the instrument for hospital nurses in Indonesia is not confirmed.Purpose: This study aims to confirm the psychometric evaluation of the Indonesian version of QNWE instruments in hospital settings.Methods: A cross-sectional study design and psychometric analyses were administered. The 65-item, eight-domain questionnaire was translated, adapted, and face-validated using content validity index (CVI) analysis. The construct validity and internal consistency of the translated version were tested using confirmatory factor analysis (CFA) and Cronbach's Alpha to 334 hospital nurses. The intraclass correlation coefficient (ICC) was employed to determine test-retest and interrater reliability analysis to 33 nurses and 10 ratters in the pilot testing.Results: The CVI of the QNWE-I scale ranged from 0.86 to 1.00. The CFA determined an adequate model fit of the instrument. As to overall reliability, test-retest reliability of 0.90, ICC analysis of 0.82, and Cronbach's alpha of 0.96; was confirmed.Conclusions: The psychometric evaluation of the QNWE-I showed excellent acceptability, validity, and reliability. Therefore, the QNWE-I can serve as a comprehensive instrument for assessing the quality of nurses' work environments in Indonesia.
