Introduction: Modified Euro Quest questionnaire to assess neurological and psychiatric effects caused by exposure to organic solvents is used. This study investigates the validity, reliability, and usability of the modified Euro Quest questionnaire in Iran. Materials and Methods: This cross-sectional descriptive study was conducted on 206 workers of color and textile industries. Modified Euro Quest questionnaire was translated into Persian by using the forward-backward translation standard method. To evaluate the content validity, convergent validity, internal consistency, and reliability of the questionnaire were used the index CVI, Pearson correlation coefficient, Cronbach's alpha, and test-retest. The convergent validity was compared, results of the questionnaire, with results of mini-mental state examination (MMSE) and Multidimensional Fatigue Inventory (MFI). Results: The relationship between the modified Euroquest questionnaire was compare with the MMSE test and the MFI's questionnaire, Pearson correlation coefficients, and the results showed in order - 0.86 and 0.65, which represents a significant inverse correlation between this questionnaire with MMSE test(p>0.001) And a moderate correlation with the MFI's questionnaire(p>0.001). Content validity index (CVI) and intraclass correlation coefficient (ICC) were obtained in order amounts of ≤0.79 and 0.92, which was acceptable. The final questionnaire, Cronbach's alpha coefficient, was calculated (α =0.84).  Conclusion: The modified Euroquest Persian version is a valuable tool to assess the neurological and psychological effects caused by exposure to organic solvents in Iranian workers.

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 The aim of this study was to adapt the instrument and evaluate the psychometric properties of the Swedish version of the Swallowing Quality of Care questionnaire (S-SWAL-CARE) in patients with oropharyngeal dysphagia. Methods Translation and adaptation of the original SWAL-CARE into Swedish was performed according to established international guidelines. Field testing was performed using 100 patients with oropharyngeal dysphagia due to multiple reasons such as head and neck cancer and neurologic/neuromuscular disease, who had undergone swallowing evaluation within 6 months prior to the study. The patients answered the S-SWAL-CARE, the Quality from the Patient’s Perspective (QPP) and the Swallowing Quality of Life (SWAL-QOL). Test–retest was performed in 20% of the participants. The reliability and validity of the S-SWAL-CARE were assessed by Pearson correlation coefficient and Cronbach’s alpha as well as convergent and discriminative validity, respectively. Results The field testing of the S-SWAL-CARE resulted in sufficient reliability, with Cronbach’s alpha values exceeding 0.90 for all domains. All items correlated strongly to their own domain, with weaker correlations to the other domains, indicating proper scale structure. Results also indicate sufficient convergent and discriminant validity when tested for association to the QPP domains and the SWAL-QOL Total score. The test–retest reliability of the S-SWAL-CARE demonstrated sufficient intraclass correlation coefficient (ICC) for the General advice domain (0.73) and Clinical advice domain (0.82). The ICC for the Patient satisfaction domain was lower (0.44). Conclusion The S-SWAL-CARE can be considered a reliable and valid tool to assess the dysphagia-related quality of care in a mixed Swedish dysphagia patient population.

Nowadays, it is common for people to look for health care information on the internet. The eHealth Literacy Scale (eHEALS) is commonly used to measure eHealth literacy. As of the publication of this study, the Indonesian version for eHEALS has not been published even though eHealth literacy is necessary, especially in the current COVID-19 pandemic. We aimed to evaluate the validity and reliability of the Indonesian version of eHEALS (I-eHEALS). A total of 100 respondents in East Java were involved in this cross-sectional study. Pearson-product moment correlation method and construct validity were used to validate the results. The reliability was determined based on the Cronbach’s alpha internal consistency measurement and intraclass correlation coefficient (ICC). The Pearson correlation analysis results are significantly higher ( r > 0.254, p < 0.01) compared to the critical value table. Single factors accounting for 57.66% variance in the scales exhibit a unidimensional latent structure. The internal consistency between items is excellent as shown by the Cronbach’s alpha coefficient (0.91). The ICC analysis shows an acceptable result (0.552, p < 0.01). The I-eHEALS is valid and reliable to be used for evaluating the eHealth literacy of the Indonesian population.

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.

Abstract Purpose To develop an Arabic version of the CPQ8–10 and test its validity and reliability for use among Arabic-speaking children. Methods The 25-item professionally translated questionnaire included two global rating questions across four domains, which was assessed through a pilot study on 20 participants who were not included in the main study. Children (n = 175) aged 8–10 years were consecutively recruited: group I (n = 120) included pediatric dental patients, group II (n = 25) included children with orofacial clefts, and group III (n = 30) included orthodontic patients. Construct (convergent and discriminant) validity, internal consistency, and test–retest reliability were assessed using Spearman’s rank correlation coefficients, Cronbach’s alpha coefficient, and intraclass correlation coefficient, respectively. All children were clinically examined; 66 children completed the questionnaire a second time. A cross-sectional study design was employed. Results CPQ8–10 scores and global ratings were positively correlated. CPQ8–10 scores were highest in group II, followed by groups I and III, respectively. CPQ8–10 scores were significantly higher in children affected with caries or malocclusion compared to unaffected children. Cronbach’s alpha was 0.95 and the intraclass correlation coefficient was 0.97. Conclusions The Arabic CPQ8–10 was valid and reliable; therefore, it can be utilized with Arabic-speaking children in this age group.

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.

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.

Family Centered

Objective: Family-centered services are collections for children with special needs and their families. These services consider families as expert about children's needs. The essence of this approach is involvement of family in decision making, cooperation, and mutual communication (family and therapist), mutual respect, acceptance of family choice, family support, flexibility of service, and effort to empower families. These services have become a basic foundation of many early intervention programs and are especially useful in rehabilitation services. MPOC-20 is one of the questionnaires used to evaluate these services. This questionnaire consists 20 questions divided into 5 areas, the areas include the following: 1) enabling and partnership, 2) providing general information, 3) providing specific information about the child, 4) coordinated and comprehensive care for child and family, and 5) respectful and supportive care. This tool has been translated and validated in several countries and specifically in several diseases. In this study, the validity and reliability of this tool have been investigated. Materials & Methods: This study was a descriptive-analytical and in order to measure the validity and reliability of MPOC-20, content validity, correlation coefficient and reliability of the test-retest were done. To determine the content validity, 14 occupational therapists were asked and the result was calculated by measuring the content validity index and content validity Ratio. Then, an MPOC-20 questionnaire along with a form of demographic information and a consent form were given to 340 parents of children (children under 18 years and with different diagnosis) in clinics of Tehran. The articipants consisted of 142 girls patients (42%) and 198 boys (58%) randomly selected from public and private rehabilitation centers in different regions of Tehran. A large percentage of respondents were mothers (314 people were 92.4%). After 2 weeks, the questionnaire was again distributed among 30 of them, and the ICC coefficients were calculated. In order to determine the internal consistency, Cronbach's alpha was calculated. Results: The content validity index and content validity Ratio for all items were acceptable and no items were deleted. Cronbach's alpha was 0.81 which indicates a high correlation between items in the questionnaire. The highest Cronbach's alpha coefficient is related to the field of providing general information about the child (α=0.77). Also, in this section, the p-value was significant for all fields at the level of 0.001. In the reliability of the test-retest, the scores of the Intra-class correlation coefficient of all domains were higher than 0/6 which indicates a medium to good reliability of the questionnaire. Reliability in the field of supportive care had a high coefficient and good reliability. In other areas, the reliability was moderate. Conclusion: Considering the importance of evaluation in improvement of family-centered services provision, a strong tool is needed and MPOC-20 is well known in this regard. The results of this study showed that the Persian version of "MPOC-20" questionnaire has a good validity and reliability in children under the age of 18, and it can be used to assess family-centered services in both research studies and as clinical tool.
