Identification of Construction Project Risks in the Indian Context: A Case Study on Building Construction

Abstract: This paper presents a comprehensive investigation into the risk factors prevalent in building construction projects within the Indian context, focusing on their identification, ranking, and management strategies. Through data collected from 206 construction professionals via an online questionnaire, the study employs robust reliability analysis, yielding a high Cronbach's Alpha coefficient of 0.898, affirming the questionnaire's internal consistency and reliability. Utilizing the Relative Importance Index (RII) and Safety Risk Score (SRS), the research ranks critical risk factors, including poor stakeholder communication, inaccurate cost estimation, funding delays, and market demand fluctuations, underlining the necessity of addressing these challenges to mitigate potential impacts on project outcomes. The paper emphasizes the significance of proactive risk management strategies to ensure project success and resilience amidst evolving circumstances, providing valuable insights into construction project risks specific to the Indian landscape and offering recommendations for enhancing risk management practices in the field.

Final Validation of the Quality of Life after Brain Injury for Children and Adolescents (QOLIBRI-KID/ADO) Questionnaire.

Until recently, no disease-specific health-related quality of life (HRQoL) questionnaire existed for pediatric traumatic brain injuries (TBIs). In this revalidation study, the psychometric properties and the validity of the 35-item QOLIBRI-KID/ADO questionnaire in its final German version were examined in 300 children and adolescents. It is the first self-reported TBI-specific tool for measuring pediatric HRQoL in individuals aged between 8 and 17 years. The six-factor model fits the data adequately. The questionnaire's internal consistency was excellent for the total score and satisfactory to excellent for the scale scores. Intraclass correlations indicated good test-retest reliability, and the measure's construct validity was supported by the overlap between the QOLBRI-KID/ADO and the PedsQL, which measures generic HRQoL. The discriminant validity tests showed that older children and girls reported a significantly lower HRQoL than comparison groups, and this was also true of children who were anxious or depressed, or who suffered from post-concussion symptoms, replicating the results of the questionnaire's first developmental study. Our results suggest that the QOLIBRI-KID/ADO is a reliable and valid multidimensional tool that can be used together with the adult version in clinical contexts and research to measure disease-specific HRQoL after pediatric TBI throughout a person's life. This may help improve care, treatment, daily functioning, and HRQoL after TBI.

Electronic health records perception among three healthcare providers specialties in Saudi Arabia: A cross-sectional study.

Worldwide, more health care facilities are adapting the use of electronic health record (EHR). Healthcare providers (HCP) have different perceptions toward the use of EHR. To investigate the perception of three classes of HCP in Saudi Arabia toward using EHR, a questionnaire (targeting satisfaction, easiness, and benefits of use as major perception indicators) was prepared. The questionnaire was assessed by an expert panel for content validity. The questionnaire internal consistency was examined using Cronbach's alpha. 108 physicians, physical therapists (PT) and respiratory care therapists (RT) from different hospitals in Saudi Arabia answered the questionnaire. Most of respondents perceived EHR systems as beneficial and made work easier. Most HCP were satisfied with the use of EHR, however, with the use of EHR more time was needed to finish the work. Age, experience, job, and job rank of HCP are of different importance in determining responses, perception, and obstacles of using EHR. Moreover, the perception of using EHR seems to be field specific. There is a positive perception among Saudi Arabia HCP about EHR use.

Cross-Cultural Adaptation, Reliability, and Validity of the Greek Version of the Fremantle Shoulder Awareness Questionnaire (FreSHAQ-GR) in Patients with Chronic Shoulder Pain.

Shoulder pain is one of the most common musculoskeletal pathologies. The association of shoulder pain with impaired proprioception and bodily self-awareness called for the cross-cultural adaptation of the Fremantle Shoulder Awareness Questionnaire (FreSHAQ) in Greek. The FreSHAQ is a relatively new self-assessment 9-item scale for impaired somatic awareness in patients with shoulder pain. The study included 100 participants (54 women) between 20 and 80 years old, with chronic shoulder pain (>3 months duration), able to comprehend and speak Greek, and recruited from three private physical therapy practices. The cross-cultural adaptation process was followed to develop the Greek version of the questionnaire (FreSHAQ-GR). Further testing for construct validity via exploratory factor analysis and correlational analysis with the Shoulder Pain and Disability Index (SPADI), the Quick Disabilities of Arm, Shoulder, and Hand (QuickDASH), the pain catastrophizing scale (PCS), a pain intensity visual analog scale (PI-VAS) in the last week, and the demographic characteristics followed. Test-retest reliability of the FreSHAQ-GR in a sub-sample of patients (n = 25) was tested upon repeated completion of the scale after a week and examined with the intraclass correlation coefficient (ICC2,1), the standard error of the measurement (SEM), and the minimum detectable change (MDC) indices. The internal consistency of the scale was also assessed. The factor analysis revealed that the scale comprised one factor relevant to shoulder awareness but with fewer items (first 6 items) than the original FreSHAQ. Additionally, the FreSHAQ-GR (both versions) demonstrated statistically significant correlations (Spearman's r) with participants' age (r = -0.31/-0.29, p < 0.002), the PI-VAS (r = 0.54/0.52, p < 0.001), the SPADI total score and both of its subscales (r = 0.39-0.45/0.34-0.39, p < 0.001), the QuickDASH (r = 0.37/0.34, p < 0.001), and the PCS (r = 0.50/0.40, p < 0.001). The questionnaire's internal consistency (Cronbach's α/McDonald's ω) was 0.833/0.827 for the 9-item and 0.871/0.867 for the 6-item FreSHAQ-GR. Test-retest reliability was excellent for both versions of the FreSHAQ-GR (ICC2,1(95% CI) = 0.97/0.98 (0.91-0.99/0.94-0.99), and with a low error margin (SEM = 1.31/0.94 and MDC95% = 3.63/2.61). Therefore, the FreSHAQ-GR (6-item version) possesses very good measurement properties and can be administered to Greek-speaking patients with chronic shoulder pain.

An adapted management of early warning signs of relapse questionnaire: Validity and reliability

BackgroundSelf-management of early warning signs of relapse is critical when it comes to having an impact on the relapse rate and developing methods to successfully handle and manage those signs of relapse. ObjectiveThe purpose of this study was to test the validity and reliability of the adapted management of early warning signs of relapse questionnaire. MethodsConsisted of two main steps: first, adapting and validating, which involved a literature review, a panel of experts, the calculation of the CVI, the Kaiser-Meyer-Olkin (KMO) test, Bartlett's test of sphericity, and exploratory factor analysis (EFA); and secondly, reliability analysis, using the test-retest method, to assess the questionnaire's internal consistency (Cronbach's alpha) and reproducibility (intraclass correlation coefficient—ICC). ResultsThe results showed that the questionnaire adapted was valid and reliable and can represent each item of the questionnaire for assessing the self-management of early warning signs of relapse. ConclusionThis proves that all 20 items used to assess it are appropriate for assessing the effectiveness of the patients' and their primary caregivers' abilities to self-manage early warning signs of relapse.

Psychometric properties of a Persian version of the Vulvovaginal Symptoms Questionnaire for measuring vulvovaginal symptoms in postmenopausal women.

Vulvovaginal symptoms are common in postmenopausal women and can affect their quality of life and sexual function. Using a sample of postmenopausal Iranian women, we evaluated a Persian translation of the Vulvovaginal Symptoms Questionnaire (VSQ). This study included 201 postmenopausal Iranian women referred to dermatology and gynecology clinics affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. We translated the VSQ to the Persian language using the forward-backward method. We examined the questionnaire's internal consistency using Cronbach α coefficient and evaluated its construct validity using exploratory and confirmatory factor analyses. A Cronbach α coefficient of 0.763 confirmed the overall internal consistency of the Persian VSQ. Exploratory factor analysis indicated that except for three items in the symptoms subscale, others had sufficient α coefficients, although some did not load on the expected subscales. Confirmatory factor analysis confirmed the appropriate allocation of all but two items to the expected subscales. An intraclass correlation coefficient of 0.89 confirmed the reliability of the questionnaire. Although some parts of the Persian VSQ were unsatisfactory, most were appropriate for assessing vulvovaginal symptoms in postmenopausal Iranian women. We recommend further cultural adaptations.

Assessing parents\u2019 self-efficacy to handle child obesity-related behaviors: validation of the Lifestyle Behavior Checklist in Iran

BackgroundThe aim of the present study was to validate the Lifestyle Behavior Checklist (LBC) questionnaire, to measure Iranian parents' perceptions of their children's weight-related behaviors and their self-efficacy in dealing with those behaviors.MethodsThe LBC was translated into Farsi. Face and content validity of the questionnaire was evaluated by an expert panel. A total of 213 mothers of 3–12-year-old children responded to the questionnaire. Criterion validity of the questionnaire was evaluated through comparing its result with a parenting style questionnaire. Principal component analysis (PCA) and confirmatory factor analyses (CFA) were used to evaluate construct validity of the questionnaire. Reproducibility was measured by twice administration of LBC, one month apart and using Spearman's rho correlation test. The questionnaire's internal consistency was assessed by calculating Cronbach's α.ResultsLBC Problem scale was significantly correlated with authoritarian parenting style score, while the Confidence scale was significantly correlated with authoritative and negatively with permissive and authoritarian parenting styles. PCA suggested a six-factor construct, including, fussy eating, food-related problem behaviors, overeating behaviors, low interest in physical activity, poor self-image and sedentary behaviors. The results of CFA indicated acceptable fit indices for the proposed models. Both, Problem scale (Cronbach's α = 0.8) and Confidence scale (Cronbach's α = 0.95) had high internal consistency. Spearman correlation coefficients indicated acceptable reproducibility for both the Problem scale (r = 0.74) and the Confidence scale (r = 0.70).ConclusionsThe Farsi version of LBC questionnaire is reliable and reasonably valid to measure Iranian mothers' perception of their children's weight-related problem behavior.

Young Children Allergic Rhinitis Questionnaire is a novel tool for allergy screening in children.

There are a limited number of validated questionnaires available for use in the clinical screening for allergic rhinitis (AR) in children ≤3years old. We developed a novel self-reported questionnaire and assessed its accuracy and reliability. After establishing a pool of items, which were screened by experts, the Young Children Allergic Rhinitis Questionnaire (YCAR-Q) was administered to a birth cohort in the Shunyi District (Beijing, China). The electronicversion of the YCAR-Q was distributed through the online community. Children were invited to visit a physician for examination. The diagnostic criteria included symptoms, physical examination findings, and specific serum immunoglobulin E tests. Each item on the questionnaire was evaluated, and the questionnaire's internal consistency, content validity, criterion-related validity, and diagnostic accuracy were assessed. The six-item YCAR-Q was distributed to 7423 parents, and 3037valid questionnaires were recovered. In total, 1521 children visited a physician for examination, of which 82 were found to have AR. In terms of internal consistency, Cronbach's coefficient was 0.777 and all six questionnaire items were retained. The average scale-level content validity index value was 1. The area under the curve was 0.759. Thetotalscoresranged from 0 to 6, and the cutoffvaluefor diagnosing AR was 3, with a sensitivity of 68.29% and a specificity of 76.58%. This cross-sectional study indicated that the YCAR-Q could detect AR in children ≤3years old. This brief and simple test may be used effectively in clinical practice.

Development and validation of a 3D laryngeal model in surgical skills training

ObjectiveTo present and validate a new simulation model for endoscopic phonomicrosurgery training as an improved teaching method. MethodsA low-cost artificial model was assembled using 3D printing, silicone, and gelatin. The study was designed to test the model's ability to carry out training and teaching of endoscopic phonomicrosurgery. The synthetic model was built to simulate normal and pathological vocal folds such as polyps, intracordal cysts and keratoses, made of silicone and gelatin and embedded in a larynx framework made by 3D printing. Simulations of endoscopic surgical procedures were performed and documented through photographs and videos and the images were submitted to the evaluation of a group of 17 otorhinolaryngologists who used a Likert scale questionnaire. The responses were submitted to an agreement analysis using the sum of the scores obtained for the responses as an appropriate level of validation. Cronbach's alpha index was calculated to measure the degree of the questionnaire internal consistency. ResultThe evaluations indicated maximum approval for the model adequacy for use in practical classes and for the teaching of the procedures, as well as in the overall satisfaction with the model in the use of surgical training. ConclusionThe present proposal for training laryngeal endoscopic surgery in a 3D synthetic model is a viable option according to the validation methodology used in the present study.

In the first section, the concept of e-professionalism in medical sciences was analyzed using the hybrid concept analysis in the theoretical work, field work, and final analysis stages in order to extract information related to the concept. In the second section, an item of the questionnaire was designed based on the concept, reviewed texts, and related questionnaires, in the third section, psychometric properties of a questionnaires were evaluated.RESULTS:Totally, 39 items were included in the initial pool, which reduced to 33 items in the final questionnaire after reviewing the psychometric properties. Factor analyses led to extraction of five factors including appraisal of e-professionalism compliance with the laws and regulations governing cyberspace, individual professionalism, knowledge management, respect for professionalism in interpersonal and group rules, and complying with ethics in the use of cyberspace. The internal consistency of questionnaire was also confirmed by Cronbach's alpha coefficient of 0.78, also all factor correlations absed stability were significant (P < 0.05).CONCLUSION:An exploratory sequential study in this study led to the extraction of five factors and development of a 33-item questionnaire in e-professionalism. As results and analysis of the psychometric properties and validation of each item, this questionnaire is valid and reliable for the assessment of levels of e-professionalism in medical sciences in Iran.

Development and Validation of the QUALI-PALLI-FAM Questionnaire for Assessing Relatives' Perception of Quality of Inpatient Palliative Care: A Prospective Cross-Sectional Survey

ContextRelatives of patients receiving palliative care are at risk for psychological and physical distress, and their perception of quality of care can influence patients' quality of life. ObjectivesThe purpose of this study was to develop and validate the QUALI-PALLI-FAM questionnaire (QUAlity of PALLIative car from FAMilies' perspective) to measure families' perception of and satisfaction with palliative care. MethodsAn exploratory factor analysis was conducted, and we evaluated the questionnaire's internal consistency using Cronbach's alpha, its stability across various strata, and the correlation between the QUALI-PALLI-FAM (factors, total score, and global satisfaction) and the total score of the FAMCARE (FAMily satisfaction with CARE) questionnaire. ResultsThis multicentric prospective cross-sectional survey was conducted in seven French hospitals, namely, three palliative care units and four standard medical units with a mobile palliative care team. The questionnaire was completed by 170 relatives of patients (more than 90% of patients had advanced cancer). The final questionnaire included 14 items across three domains: organization of care and availability of caregivers, medical information provision, and confidence and involvement of relatives. Internal consistency was good for all subscales (Cronbach's α = 0.74–0.86). Our questionnaire was stable across various strata: age and gender (patients and relatives), Palliative Performance Scale scores, and care settings. The QUALI-PALLI-FAM total score was correlated with the total FAMCARE score. ConclusionThe QUALI-PALLI-FAM appears to be a valid, reliable, and well-accepted tool to explore relatives' perception of quality of inpatient palliative care and complements the QUALI-PALLI-PAT questionnaire. Further testing is required in various settings and countries.

Cross-cultural adaptation, from Dutch to Swedish language, of the Individual Work Performance Questionnaire.

There is a need for a short, self-rated, validated and reliable instrument for individual work performance suitable for generic use in the Swedish work and organizational context. The Individual Work Performance Questionnaire (IWPQ), comprising originally 47 items, was initially developed in the Netherlands, based on a four-dimensional conceptual framework, in which individual work performance consisted of task performance, contextual performance, adaptive performance, and counterproductive work behavior. During the development process, IWPQ was shortened to 18 items with three scales formally labeled as Task performance, Contextual performance, and Counterproductive work behavior (CWB), capturing three work performance types. The current version of the IWPQ, consisting of 18 items and three scales, was then translated as well as cross-culturally adapted to American-English and Indonesian contexts. To translate and adapt the current IWPQ version, consisting of 18 items, from the Dutch to the Swedish context, to assess its content validity through cognitive interviews, to apply it to a pilot group to present descriptive statistics, to calculate the questionnaire's internal consistency, as well as to clarify whether the translated items capture three or four performance types. The Dutch version of the IWPQ, consisting of 18 items, was translated into Swedish. A six-stage translation and adaptation process was used: forward translation, synthesis, back translation, harmonization, cognitive interviews, revision, and sampling and analyses of pilot data for 206 managers (149 women) from five Swedish municipalities. IWPQ instructions, wording of a few items and one response form were slightly modified. The pilot testing showed Cronbach's alphas similar to the Dutch version of the IWPQ, ranging between 0.73 and 0.82, good mean-inter-item correlations (all above 0.36). In deciding how many factors to retain, we employed both parallel analysis (PA), and Velicer's minimum average partial (MAP) test. The number of factors to retain was, as indicated by PA, four, and by MAP, three or four. Exploratory factor analysis (principal axis factoring) revealed clearly separate factors, corresponding to four, rather than three, performance types. A new factor, roughly representing adaptive performance, comprised in the original, longer version of the IWPQ, emerged. The Swedish version of the IWPQ was successfully translated and adapted in a pilot group of managers. Before it is used, it should be validated in a larger group of managers and in more heterogeneous groups of both white- and blue-collar workers.

Immersion experience of medical students and related influencing factors

Objective To investigate the current status and characteristics of the immersion experience of medical students and related influencing factors. Methods The stratified random sampling method was used to conduct a survey using an immersion experience questionnaire among 732 medical students in a full-time university. Epidata 3.1 software was used for data double entry and management, and SPSS 19.0 statistical software was used for data processing and statistical analysis. The questionnaire internal consistency reliability test was used to assess the validity of the questionnaire and a logistic regression analysis was used to identify the influencing factors for the immersion experience of medical students. Results Learning immersion experience was at a moderate level among the medical students (3.13±0.64). Level of performance (OR=1.177, 95%CI=0.988-1.402), degree of satisfaction with learning (OR=1.674, 95% CI=1.341-2.089), and professional interest (OR=2.153, 95%CI=1.776-2.610) were the positive influencing factors for learning immersion (P 0.05). Conclusion Learning immersion experience is at a moderate level among medical students. Improvement of medical students' performance, learning satisfaction, and professional interest helps to improve their immersion experience. Strengthening the attention to work immersion and enhancing learning immersion experience among medical students are beneficial to medical student education and cultivation of qualified medical talents. Key words: Medical student; Learning immersion; Current status investigation; Influencing factor

Reliability and Concurrent Validity of a Culturally Adapted Persian Version of the Brace Questionnaire in Adolescents With Idiopathic Scoliosis

Study DesignCross-sectional. ObjectivesTo determine the validity and reliability of culturally adapted Persian version of the Brace Questionnaire (P-BrQ). Summary of Background DataThe BrQ has proved to be a reliable and valid instrument for evaluating the quality of life of adolescents with idiopathic scoliosis and has been translated to different languages. But, lack of a Persian translated version makes its use impractical in the Persian speaking scoliotic patients. MethodsForward and backward translation of P-BrQ was conducted according to the International Quality of Life Assessment guidelines. The final version of the P-BrQ was administered to 51 adolescents (1 boy and 50 girls) with idiopathic scoliosis. The mean age of the participants was 13.88 ± 2.14 years. The questionnaire's internal consistency was determined using Cronbach's alpha. A subgroup of 38 participants were randomly selected to complete the BrQ for a second time one week later. The test-retest reliability was then analyzed using the intraclass correlation coefficient, while the concurrent validity was assessed by comparing the BrQ with the Scoliosis Research Society-22 questionnaire. ResultsThe total Cronbach's alpha coefficient of the P-BrQ was 0.96, and the overall intraclass correlation coefficient of the questionnaire was also 0.96. The intraclass correlation coefficients for the corresponding domains were as follows: general health perception, 0.96; physical functioning, 0.96; emotional functioning, 0.98; self-esteem, 0.80; vitality, 0.97; school activity, 0.98; pain, 0.97; and social functioning, 0.98. ConclusionsThe culturally adapted Persian version of the BrQ can be used to assess the quality of life of adolescents with idiopathic scoliosis who wear a brace. Level of EvidenceII.

Clinical Validation of The Portuguese Version of the Children's Sleep Habits Questionnaire (CSHQ-PT) in Children with Sleep Disorder and ADHD

The Portuguese version of the Children's Sleep Habits Questionnaire showed adequate psychometric properties in a community sample but the American cut-off seemed inadequate. This study aimed to validate this questionnaire in clinical populations of children with sleep disorders and with attention deficit/ hyperactivity disorder. The study sample included 148 Portuguese children aged 2 to 10 years old that where divided in 3 groups: 1. Clinical group with sleep disorders (behavioral insomnias, parasomnias or sleep-related breathing disorders); 2. Clinical group with attention deficit/ hyperactivity disorder; 3. The sleep habits and sleep problems were evaluated using the Children's Sleep Habits Questionnaire. Sleep-related disorders were confirmed by polysomnography. The questionnaire's internal consistency (Cronbach α) in the clinical sample (sleep disorders and attention deficit/ hyperactivity disorder) was 0.75 and ranged from 0.55 to 0.85 for the subscales. Children with sleep disorders and attention deficit/ hyperactivity disorder had a higher sleep disturbance index (full scale score) compared to the control group. The subscales presented significant differences between the subgroups with different sleep disorders showing discriminative validity. The receiver operating characteristic analysis of the sleep disturbance index comparing the sleep disorder and control sample determined a cut-off of 48 (sensibility 0.83; specificity 0.69). Children with sleep disorders and attention deficit/ hyperactivity disorder evidenced higher Sleep Disturbance Index (full scale score) comparing to the control group. The subscales presented significative differences between the subgroups with different sleep disorders showing discriminative validity Conclusion: The Portuguese version of the Children's Sleep Habits Questionnaire showed adequate psychometric properties for children with sleep disorders and/or attention deficit/ hyperactivity disorder. The cut-off value 48 is better adjusted for the Portuguese population.

Reliability and validity study of the Spanish adaptation of the "Creighton Simulation Evaluation Instrument (C-SEI)".

There are multiple advantages to using human patient simulation (HPS) as a teaching method for clinical nursing education. Valid, reliable tools that can be used when applying this teaching method are needed to evaluate nursing student skill acquisition. The aim of this study was to translate the Creighton Simulation Evaluation Instrument (C-SEI) into Spanish and to analyse the reliability and validity of the Spanish C-SEI version with nursing students. The study was conducted in two phases: (1) Adaptation of the instrument into Spanish. (2) Cross-sectional study in a sample of 249 nursing students who were evaluated by two observers. The psychometric properties were analysed in terms of reliability (internal consistency and inter-observer consistency) and construct validity using an exploratory factor analysis. Questionnaire internal consistency was 0.839 for the tool as a whole. Inter-observer concordance for the tool as a whole was 0.936 and greater than 0.80 for the majority of the items. The exploratory factor analysis showed a four-factor structure that explains 49.5% of the total variance. The results of this study show that the C-SEI-sp tool is a valid and reliable tool that is easy to apply in the monitoring of student performance in clinical simulation scenarios.

Objective To prepare the questionnaire for Knowledge-Attitude-Practice of chemotherapy-induced nausea and vomiting (CINV) for nurses in tumor hospital, and to test its reliability and validity. Methods Based on Knowledge-Attitude-Practice theory, a questionnaire was compiled based on literature reading, group discussion and expert consultation. A stratified cluster sampling method was used to extract 311 nurses from a three-tumor hospital, Department of oncology and gynecology. The reliability was tested by Cronbach's alpha coefficient, test-retest reliability and split half reliability. The content validity and exploratory factor analysis were used to test the validity of the questionnaire. Results This questionnaire has 55 items. The principal component analysis extracts 5 public factors, including the CINV related definition, the influence factors of CINV, the drug and non drug control methods of CINV, the attitude of CINV and the CINV behavior, and the cumulative contribution rate was 52.99%, and the common variance of each project was more than 0.4. The total questionnaire internal consistency reliability and split half reliability were 0.949 and 0.941. Conclusion The questionnaire on Knowledge-Attitude-Practice of chemotherapy-induced nausea and vomiting of nursing staff has good reliability and validity. It can be used as a reliable tool for the investigation of chemotherapy related knowledge, attitude and behavior of nursing staff in cancer specialist hospital and the investigation of influencing factors. Key words: Chemotherapy; Nausea and vomiting; Knowledge-attitude-practice; Reliability; Validity

Factor structure and internal consistency of a Swedish version of the Pain Catastrophizing Scale.

Pain catastrophizing is highly relevant to assess in the context of long-standing pain. The Pain Catastrophizing Scale (PCS) is a well-established questionnaire used to measure catastrophizing in individuals with long-standing pain. So far, no Swedish translation has been evaluated in regard to validity and reliability. The aims of this study were to translate the PCS questionnaire from English to Swedish, and to investigate its construct validity (face, content, and structural validity) and reliability (internal consistency). We translated the original English version of the PCS to Swedish and collected item responses from 194 persons suffering from primarily long-standing musculoskeletal pain. We used confirmatory factor analysis to evaluate structural validity, and tested the model fit of a one-factor model, an oblique two-factor model, and an oblique three-factor model. We evaluated the measure's reliability in regard to internal consistency calculated with Cronbach's alpha. A three-factor model comprising a four-item rumination factor, a three-item magnification factor, and a six-item helplessness factor provided the best fit to the data. Internal consistency was adequate and Cronbach's α was 0.92 for the entire scale, 0.84 for the rumination subscale; 0.69 for the magnification subscale, and 0.89 for the helplessness subscale. The results indicated adequacy of a three-factor solution and the questionnaire's internal consistency, and provide initial support for the structural validity and internal consistency of a Swedish version of the PCS. Future studies should replicate the study in larger samples and extend the current evaluation in regard to validity and reliability.

Development and psychometric properties of the Hookah Smoking Initiation for Women Questionnaire (HIWQ).

The aims of this study were to design the Hookah Smoking Initiation for Women Questionnaire (HIWQ) and determine its psychometric properties. This was a sequential exploratory mixed-methods design consisting of qualitative and quantitative phases. This study was conducted from August 2012 to July 2013 in Tehran. In the qualitative phase, semi-structured interviews were held with 36 Iranian women for developing a preliminary item pool. Consequently, during the quantitative phase, the psychometric properties of the questionnaire were determined with the collaboration of 323 women living in various geographical locations in Tehran, Iran. Content validity of the questionnaire was examined by a panel of experts. The questionnaire's construct validity was assessed using exploratory factor analysis and confirmatory factor analyses. The Cronbach's alpha coefficient was calculated to check the questionnaire's internal consistency reliability. Moreover, its stability was tested using the test-retest method. Exploratory factor analysis indicated that the HIQW could best be explained by a six-factor solution: 'drawing the attention of other people', the need to having fun and being relaxed, 'hookah smoking in the family', 'availability of hookah', 'curiosity' and 'having a positive attitude toward hookah'. It also was found that the construct and content validity, and the reliability of the questionnaire were satisfactory (α = 0.83, ICC = 0.94). The HIQW was valid and reliable. Therefore, healthcare professionals can use it for evaluating the hookah smoking initiation in women. Future studies are required to refine this questionnaire and assess its applicability in different cultures and contexts.
