Assessment Questionnaire

The 10-item Behavior Assessment Questionnaire (BAQ) was developed to assess parent-report of child screen time, physical activity, and food consumption during the past 3 months in children with obesity. Response options were on a 5-point scale, converted to 0-100, with higher scores indicating healthier behavior. To evaluate, two convenience samples of parents of children 5-18 years completed the questionnaire: a cohort presenting to an obesity program (n=83) and a cohort of community events attenders and hospital employee parents (n=147). Scores had a normal distribution without floor or ceiling effects. Cronbach's alpha for the 10-item scale was .71. Factor analysis yielded three component factors with Cronbach's alpha of .66, .75, and .59 for the Screen Time, Physical Activity, and Food Consumption dimensions respectively. Scores of the obesity group (49.02 [SD 14.52]) were lower than scores of the community group (55.44 [SD 13.55]), p=.001. The BAQ demonstrated reliability and validity for use as an index of lifestyle behaviors.

Abstract Introduction Facial nerve palsy results in both functional disability and psychological morbidity. There are several well-established grading scales to quantify the quality of life of these patients. Objective Translate and validate the Facial Clinimetric Evaluation (FaCE) scale and Synkinesis Assessment Questionnaire (SAQ) to Brazilian Portuguese. Methods This study adopted a forward-backward translation method and performed cross-cultural adaptation. A pilot study was conducted to correct any confusing language and to evaluate content validity. A validation study was then performed. Internal consistency of the Brazilian Portuguese version of the FaCE and SAQ items was evaluated by Cronbach’s alpha coefficient. Construct validity was assessed by Spearman’s Rank Correlation Coefficient between FaCE and SAQ scores to eFACE, House-Brackmann, Short Form 12 (SF-12) and Facial Disability Index (FDI) (sub)scores. Results A total of 90 patients were included. Cronbach’s alpha for total domain scored 0.881 for FaCE and 0.809 for SAQ. FaCE total score correlation to eFACE total and House-Brackmann showed Spearman’s r value of 0.537 and −0.538, respectively (p < 0.001). SAQ correlation to eFACE synkinesis subdomain was −0.449 (p < 0.001). No correlation was found between SAQ and HB score. FaCE total score correlations were of 0.301 and 0.547 for SF-12 PCS and MCS, respectively (p < 0.001). Correlation between FaCE total and FDI Physical and Social/well-being functions were 0.498 and 0.567 (p < 0.001). Conclusion Brazilian Portuguese FaCE scale and SAQ versions achieved high validity and reliability in the present study. These translated instruments demonstrated good psychometric properties, being proper to use in clinical practice in Brazil and with Brazilian Portuguese speakers.

Background Over the last three decades, the accessibility and usage of mobile devices have increased among young children. This study’s objective was to develop a validated caregiver-reported digital-screen exposure questionnaire (DSEQ) for children aged 2–5 years. Methods DSEQ was developed in five phases. Phase 1, a draft questionnaire was developed by reviewing the literature on existing tools (n = 2) from 2009–2017. Phase 2, face-to-face interviews with primary caregivers (n = 30) were conducted in a tertiary-care-hospital for acculturation. Nine experts assessed the face and content validity of the draft Hindi and English questionnaire. Phase 3, a pilot study conducted among randomly selected families (n = 40) to evaluate the feasibility of DSEQ in field settings. Phase 4, test-retest reliability was done among 30 primary caregivers selected randomly in another urban cluster. Phase 5, the internal consistency of DSEQ was checked by conducting a cross-sectional study among randomly selected 400 primary caregivers in Chandigarh, North India. IBM SPSS Statistics for Macintosh, version 25.0, was for data management and analysis. Results A valid DSEQ with 86 items under five domains, including sociodemographic, screen-time exposure and home media environment, level of physical activity, media-related behaviors, and parental perceptions was developed. The pilot study showed that it was feasible to use the DSEQ in the field. DSEQ was reliable with kappa value ranging from 0.52 to 1.0, and intra-class coefficient of 0.62–0.99 (p<0.05). A strong internal consistency was observed for three domains including, screen-time exposure and home media environment (Cronbach’s alpha of 0.82), media-related behaviors (Cronbach’s alpha of 0.74) and physical activity (Cronbach’s alpha 0.73). Conclusions The developed DSEQ has good face and content validity and acceptable evidence of internal consistency and test-retest reliability. The DSEQ can be used for measuring digital screen exposure and its correlates among children aged 2 to 5 years.

Simple Definition

The Psychology of Religion has had a tradition measuring things that are seemingly difficult to measure, such as one’s level of religiosity or spirituality – concepts that are polysemantic, so do not have a simple definition. In doing so, researchers have developed scales to measure such constructs. This trend in Psychology of Religion research will continue as researchers start to conduct studies in non-Western Educated Industrialized Rich Democratic (WEIRD) populations, as they will require new scales that are appropriate for the way that these populations conceptualize religiosity and spirituality. Scale construction takes multiple steps, which most researchers are well-acquainted with. One important step is to demonstrate both validity and reliability. In the Psychology of Religion, an overwhelming majority of researchers use Cronbach’s alpha to estimate scale reliability. However, alpha has multiple preconditions that can easily be violated in psychology research that are rarely tested for, let alone adjusted for. Much like with using parametric statistical analyses when parametric assumptions are violated, this approach may be leading to inaccurate reporting. This article will discuss; (1) whether alpha should be used at all in Psychology of Religion research and, if so, when it is appropriate; (2) introduce another estimate of scale reliability, Omega, and show how and it might be calculated; (3) provide examples of how these techniques might be taught to students studying Psychology of Religion at undergraduate and higher levels. In doing so, I hope to move the entire field of Psychology of Religion forward in terms of methodological rigor.

Background Evidence-based medicine (EBM) is a widely accepted scientific advancement in clinical settings that helps achieve better, safer, and more cost-effective healthcare. However, presently, validated instruments to evaluate healthcare professionals’ attitude and practices toward implementing EBM are not widely available. Therefore, the present study aimed to determine the validity and reliability of a newly developed knowledge, attitude, and practice (KAP) questionnaire on EBM for use among healthcare professionals. Methods The Noor Evidence-Based Medicine Questionnaire was tested among physicians in a government hospital between July and August 2018. Exploratory factor analysis and internal consistency reliability-based Cronbach’s alpha statistic were conducted. Results The questionnaire was distributed among 94 physicians, and 90 responded (response rate of 95.7%). The initial number of items in the KAP domains of the Noor Evidence-Based Medicine Questionnaire were 15, 17, and 13, respectively; however, two items in the practice domain with communalities <0.25 and factor loadings <0.4 were removed. The factor structure accounted for 52.33%, 66.29%, and 55.39% of data variance in the KAP domains, respectively. Cronbach’s alpha values were 0.81, 0.81, and 0.84 for KAP domains, respectively, indicating high reliability. Conclusions This questionnaire can be used to evaluate the knowledge, attitudes, and behaviour of healthcare professionals toward EBM. Future testing of this questionnaire among other medical personnel groups will help expand the scope of this tool.

The validity analysis of the scale for the data collected was performed with exploratory factor analysis and item-total correlation tests, while the property of reliability was determined using the Cronbach’s alpha internal consistency coefficient and the stability test was carried out by determining the relationship between two applications conducted at an interval of the five weeks. The scale, which is called the “Scale for Determining the Civic-Mindedness Levels of Individuals” is a five-step Likert-type scale and consists of 27 items that can be collected under three factors. The factor names are “Openness to Criticism/Development”, “Participation/Activeness” and “Lack of Prejudice/Flexibility”. The KMO value of the scale was 0.956; and the Bartlett Test values were x2=11001.719; sd=351; p<0.000. Items in the scale accounted for 56.619% of the total variance. As a result of the confirmatory factor analysis, the χ2 value was 808.07 and the degree of freedom was 321. Χ2/df is 2.51. The fit indices of the scale were determined as RMSEA=0.067; S-RMR=0.049; NFI=0.97. The item-total corrected correlation coefficients of the items in the scale varied between 0.40 and 0.703 (p<.01). The reliability coefficient of the scale was Cronbach’s alpha at 0.954 and the stability coefficients of the items were between 0.496 and 0.674 (p<,01).

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.

Background: The physical activity has been indicated as an experience that can help achieve positive, self-oriented own body awareness. This awareness is an aspect that tends to get worse with age. Objective: Our study aims to verify the internal consistency of a questionnaire on physical awareness in a sample of Italian elders; a secondary objective is to measure if there is a relationship between physical awareness and perceived level of physical activity. Methods: Cross sectional study on a consecutive sample of elderly people was administered the “Physical Body Experiences Questionnaire simplified for active aging (PBE-QAG)”, inspired by the “Physical Body Experiences Questionnaire”, modified, simplified and adapted to be used in the elderly over 65. To elderly people the International Physical Activity Questionnaire. Cronbach’s alpha was also used to assess internal reliability of the total PBE-QAG. The factor structure was evaluated through Confirmatory Factor Analyses (CFAs). Results: The Cronbach’s alpha was 0.8 for the “body-mind relationship” scale, 0.81 for the “accepting your body” scale, 0.83 for the “awareness of physical skills” scale, and 0.65 for the “awareness of physical limits” scale. Cronbach’s alpha for the total PBE-QAG was 0.89. The CFA indicated a model with the 4 factors (CFI = 0.989, TLI = 0.984, RMSEA = 0.076). People who conducted physical activity assiduously or regularly and over 10 minutes showed a better score to the PBE-QAG than those who declared a sporadic activity and for “less than 10 minute”, respectively. Conclusion: Our study revealed that the PBE-QAG shows an excellent total internal consistency. In the Italian sample of elderly people the questionnaire shows the model with the 4 factors described in literature.

ABSTRACT Objective: To validate the construct and test the reliability of the Brazilian version of Hypertension Knowledge-Level Scale. Methods: Methodological research with 220 participants in a primary health care unit from Curitiba, Paraná. The data were collected with a social demographic questionnaire and the Brazilian version of the scale. The construct validity and reliability were assessed using Cronbach’s Alpha, Pearson’s Correlation and Analysis of Variance. The discriminant validity was verified comparing groups of people with hypertension and without, using T test. Results: Cronbach’s Alpha was 0.74. The groups comparison showed that people with hypertension had better results (p<0,001). Pearson’s Correlation showed that the questions measure different aspects of the same construct, justifying its organization in subdimensions. Conclusion: The Brazilian version of Hypertension Knowledge-Level Scale is a reliable instrument, which had its construct and criterion validated to measure knowledge about hypertension among Brazilian people. It can help health professionals with planning educative actions.

Abstract: Introduction: The humanities are associated with the improvement of medical students’ personal qualities. To date, there are no research instruments that quantify the exposure of medical students have to the humanities. Hence, the availability of a questionnaire with such characteristics in Brazilian Portuguese sets a precedent for the planning and implementation of educational strategies and policies addressing this topic. Objective: to translate and transculturally adapt the “HUMANITIES SCORE (LIFE EXPERIENCES + ATTITUDES) questionnaire, determine its validity and reliability, as well as identify the type of exposure to the humanities of the assessed population. Method: The original version of the questionnaire, written in English, was translated according to what is recommended by the specialized literature, with the addition of some activities in the humanities field, as per the original authors’ suggestion. The translated instrument underwent a pre-test with 31 medical students for semantic validation, followed by the application of its final version to 258 students. The exploratory and the confirmatory factorial analyses were applied to assess the instrument with its internal consistency was checked with Cronbach’s Alpha coefficient. Result: The final questionnaire was administered to the students to verify their type of exposure to the humanities. After the statistical tests were carried out, the final version of the instrument, named “Escala de Exposição às Humanidades” (EEH), included 17 items with Likert-scale responses with five options each, and obtained a Cronbach’s alpha of 0.689. The mean score of the students’ exposure was 1.72 ± 0.37, being influenced by the period at medical school, the number of volunteer social activity experiences, the participation in religious groups, the practice of meditation, and the involvement in political activities. Variables such as female gender, engagement in previous actions related to the humanities before starting medical school and in religious ceremonies positively influenced the students’ opinion about the importance of the humanities for the medical curriculum. Conclusion: The EEH demonstrated reliability in its structure and content, allowing correlations between the students’ exposure to humanities and their opinion about the importance of human sciences in the medical curriculum. It constitutes the first instrument that aims at measuring the humanities exposure rate in Brazil; however, further studies must be carried out, to better validate the instrument.

Background: Kinesiophobia is described as fear of physical movement resulting in painful injury. Older adults with knee osteoarthritis usually suffer from joint pain. Assessment of kinesiophobia is beneficial for prevention of further deterioration in performing activity. Even though, the Tampa Scale of Kinesiophobia (TSK-11) has been developed to briefly examine pain related to fear of movement in patients with chronic pain, the TSK-11 Thai version has not been examined for its validity and reliability yet. Objective: To examine psychometric properties of the TSK-11 Thai version. Materials and Methods: A cross-sectional study with 200 older people with knee osteoarthritis living in the northeastern part of Thailand was used in the present study. Participants were asked to complete the demographic questionnaire, the TSK-11-Thai version, the numeric rating scale (NRS), and the Pain Catastrophizing Scale (PCS) Thai version. To confirm the TSK-11 Thai version validity, construct validity was examined using confirmatory factor analysis. Pearson correlation coefficients were used to confirm the TSK-11-Thai version’s convergent validities. For internal consistency reliability, Cronbach’s alpha coefficients were also assessed. Results: The results of confirmatory factor analysis indicated that a two-factor model, including somatic factor and activity avoidance, fitted with the data. The TSK11-Thai version was positively correlated with pain catastrophizing. Cronbach’s alpha coefficients of the total TSK11-Thai version was at 0.77. For subscale, Cronbach’s alpha coefficients of the TSK somatic factor and activity avoidance were 0.61 and 0.69, respectively. Conclusion: The Thai version of TSK-11 has acceptable validity and reliability. The TSK-11-Thai version is suitable to use to examine pain-related fear of movement in patients with knee osteoarthritis for clinical and research purposes.
