Abstract Introduction Oropharyngeal dysphagia (OD) is a disorder that can have devastating and long lasting effects on a person’s medical, mental and psychosocial well-being, thus negatively impacting quality of life. There is currently no validated dysphagia-specific quality of life instrument in Norway. This project aims to evaluate the psychometric properties of the culturally adapted Norwegian version of SWAL-QOL (Nor-SWAL-QOL). Methods The original SWAL-QOL was translated into Norwegian according the international translation guidelines. A group of 102 persons with OD and a group of 123 healthy controls were recruited to assess the validity and reliability of the Nor-SWAL-QOL. Correlation analysis of the Nor-SWAL-QOL and the Short Form 36 (SF-36) and correlation analysis of OD group and control group Nor-SWAL-QOL subscale scores were computed to determine convergent, discriminant, and known-groups validity which help comprise construct validity. Internal consistency, test-retest reliability and intraclass correlation coefficient (ICC) were computed for reliability. Results Convergent and discriminant validity was demonstrated between Nor-SWAL-QOL subscales and SF-36 domains, and distinguished between persons with and those without oropharyngeal dysphagia on all subscales and on the symptom frequency battery (p < 0.001). Additionally, the Nor-SWAL-QOL differentiated between symptom severity levels within the OD group; those requiring food and liquid modifications and those who are tube fed and not tube fed. Nor-SWAL-QOL showed good reliability with adequate internal consistency (Cronbach’s α ≥0.70), test-retest reliability (Spearman’s rho values 0.68–0.90) and ICC values (0.67–0.89) for all subscales and for the symptom frequency battery. Conclusion Access to valid and reliable dysphagia-specific QoL outcome measures for health care practitioners, dysphagia clinicians and researchers is necessary for comprehensive assessment and treatment outcome measures. The Nor-SWAL-QOL exhibits sufficient psychometric properties for implementation in the Norwegian population.

Background and Objectives. Health Related Quality of Life (HRQoL) is an important health outcome measure in haemophilia. The aim of this study was to assess the psychometric properties of the Greek version of Haem-A-QoL, a disease-specific questionnaire for haemophiliacs.Methods. Haem-A-QoL and SF-36 were administered to 118 adult haemophilia patients. Hypothesized scale structure, internal consistency (Cronbach’sα), and test-retest reliability, as well as various types of construct validity were evaluated.Results. Scale structure of Haem-A-QoL was confirmed, with good item convergence (87%) and discrimination (80.6%) rates. Cronbach’sαwas >0.70 for all but one dimension (dealing) and test-retest reliability was significantly high. The strength of Spearman’s correlations between Haem-A-QoL and SF-36 scales ranged from 0.25 to 0.75 (P<0.01). Multiple stepwise linear regression analysis revealed that all but one Haem-A-QoL dimensions were important predictors of SF-36 scales. Known-groups comparisons yielded consistent support of the instruments’ construct validity and significant relationships were identified for age, educational level, haemophilia type, disease severity, and viral infections.Conclusion. Overall, the psychometric properties of the Greek version of Haem-A-QoL, resulting from this first time administration of the instrument to Greek adult haemophiliacs, confirmed it as a reliable and valid questionnaire for assessing haemophilia-specific HRQoL in Greece.

Abstract Background People are living longer than ever before. However, with living longer comes increased problems that negatively impact on quality of life and the quality of death. Tools are needed to help individuals assess whether they are practicing the best attitudes and behaviors that are associated with a future long life, high quality of life, high quality of death and a satisfying post-death legacy. The purpose of paper is to describe the process we used to develop a novel questionnaire (“Preparedness for the Future Questionnaire™ or Prep FQ”) and to define its psychometric properties. Methods Using a multi-step development procedure, items were generated, for the new questionnaire after which the psychometric properties were tested with a heterogeneous sample of 502 Canadians. Using an online polling panel, respondents were asked to complete demographic questions as well as the Prep-FQ, Global Rating of Life Satisfaction, the Keyes Psychological Well-Being scale and the Short-Form 12. Results The final version of the questionnaire contains 34 items in 8 distinct domains (“Medico-legal”, “Social”, “Psychological Well-being”, “Planning”, “Enrichment”, “Positive Health Behaviors”, “Negative Health Behaviors”, and “Late-life Planning”). We observed minimum missing data and good usage of all response options. The average overall Prep FQ score is 51.2 (SD = 13.3). The Cronbach alphas assessing internal reliability for the Prep FQ domains ranged from 0.33 to 0.88. The intra-class correlation coefficient (ICC) used to assess the test–retest reliability had an overall score of 0.87. For the purposes of establishing construct validity, all the pre-specified relationships between Prep FQ and the other questionnaires were met. Conclusion Analyses of this novel measure offered support for its face validity, construct validity, test–retest reliability, and internal consistency. With the development of this useful and valid scale, future research can utilize this measure to engage people in the process of comprehensively assessing and improving their state of preparedness for the future, tracking their progress along the way. Ultimately, this program of research aims to improve the quality and quantity of peoples live by helping them ‘think ahead’ and ‘plan ahead’ on the aspects of their daily life that matter to their future.

The purpose of this study was to adapt the Spitzer Quality of Life Index and evaluate its reliability in patients with low back pain. The following steps were followed: translation, back-translation, evaluation by a committee, and pretest. The reliability was estimated through stability and homogeneity assessment. The validity was tested comparing scores of the Spitzer (QLI) with the SF-36 and the Roland-Morris. The psychometric properties were evaluated by the self-application on 120 patients. Results showed that the Cronbach's Alpha was 0.77. Intraclass correlation coefficient for test-retest reliability was 0.960 (p<0.001; IC95%: 0.943; 0.972). Spearman´s correlation coefficient for test-retest reliability was 0.937 (p<0.001). There was significant correlation between the Spitzer (QLI) scores and the dimensions of the SF-36. A significant negative correlation was found between the Spitzer (QLI) and the Roland-Morris scores (r = - 0.730). The adaptation process was conducted successfully and the questionnaire presented reliable psychometric measures.

Background: Neuromuscular disorders affect physical and mental aspects of a patient and in other words alter the patients’ quality of life (QOL). In the present study, we investigated the validity and reliability of the Persian version of Individualized Neuromuscular QOL (INQOL) to provide a better insight into patients’ QOL. Methods: Original version of the INQOL was translated backward and then forward. The resultant Persian version and a standard questionnaire, 36-Item Short Form Health Survey (SF-36), were then given to 83 participants with neuromuscular disorders. Internal consistency, known-group validity, concurrent validity, and test-retest reliability were assessed. Results: The scores of matched sections for QOL in the two questionnaires were favorably correlated (P < 0.05). Correlation between test and retest scores was also significant (P < 0.05). Moreover, the Cronbach’s alpha of 0.82 was representative of robust internal consistency between INQOL covering sections. Conclusion: The Persian version of the INQOL can be used in clinical and research practice to detect changes in QOL which are related to neuromuscular disorders, due to its favorably reliable and valid characteristics.

Background: The number of children worldwide requiring palliative care services is increasing due to advances in medical care and technology. The use of outcome measures is important to improve the quality and effectiveness of care. Aim: To systematically identify health-related quality-of-life outcome measures that could be used in paediatric palliative care and examine their feasibility of use and psychometric properties. Design: A systematic literature review and analysis of psychometric properties. Data sources: PsychInfo, Medline and EMBASE were searched from 1 January 1990 to 10 December 2014. Hand searches of the reference list of included studies and relevant reviews were also performed. Results: From 3460 articles, 125 papers were selected for full-text assessment. A total of 41 articles met the eligibility criteria and examined the psychometric properties of 22 health-related quality-of-life measures. Evidence was limited as at least half of the information on psychometric properties per instrument was missing. Measurement error was not analysed in any of the included articles and responsiveness was only analysed in one study. The methodological quality of included studies varied greatly. Conclusion: There is currently no ‘ideal’ outcome assessment measure for use in paediatric palliative care. The domains of generic health-related quality-of-life measures are not relevant to all children receiving palliative care and some domains within disease-specific measures are only relevant for that specific population. Potential solutions include adapting an existing measure or developing more individualized patient-centred outcome and experience measures. Either way, it is important to continue work on outcome measurement in this field.

Sexual dysfunction has been demonstrated to be related to a poor quality of life. These dysfunctions are especially prevalent among men. This cross-sectional study aimed to investigate the psychometric properties of the Persian translation of the Sexual Quality of Life–Male (SQOL-M), translated and adapted to measure sexual quality of life among Iranian men. Forward–backward procedures were applied in translating the original SQOL-M into Persian, and then the psychometric properties of the Persian translation of the SQOL-M were studied. A total of 181 participants (23-60 years old) were included in the study. Validity was assessed by construct validity using confirmatory factor analysis, convergent validity, and content validity. The international index of erectile function (IIEF) and the work ability index were used to study the convergent validity. Reliability was evaluated through internal consistency and test–retest reliability analyses. The results from confirmatory factor analysis confirmed a one-factor solution for the Persian version of the SQOL-M. Content validity of the translated measure was endorsed by 10 specialists. Pearson correlations indicated that work ability index score, dimensions of the IIEF, and the IIEF total score were positively correlated with the Persian version of the SQOL-M ( p < .001). Reliability evaluation indicated a high internal consistency and test–retest reliability. The Cronbach’s alpha coefficient and intraclass correlation coefficients were .96 and .95, respectively. Results indicated that the Persian version of the SQOL-M has good to excellent psychometric properties and can be used to assess the sexual quality of life among Iranian men.

Quality of life (HRQoL) is a measure of a person's health in physical, spiritual, and emotional, and role functions in the society. Measurement of quality of life (HRQoL) is an important thing to understand and evaluate. Measurements are carried out not only on patients but also on the general population with the use of specific or generic instruments. The instrument used requires a psychometric properties test to ensure its validity and reliability. This article aims to conduct a systematic review of the psychometric properties of quality of life (HRQoL) instruments in the general population. Articles were collected in December 1st to 5th, 2018, from Pubmed and Google Scholar. The assessment was carried out using the checklist properties according to the cohen criteria and included the content validity, construct validity, internal consistency reliability, test-retest, ceiling effect and the level of credibility of the instruments. Among 80 articles obtained there were 24 articles that fulfilled the inclusion criteria. Short Form-36 (SF-36) instrument is the most widely used instrument in measuring the quality of life in the general population (26.6%). Some instruments have not been tested according to the criteria, while almost all instruments show a good level of validation of construct validity using convergent and discriminat validity with cronbach alpha values > 0.7. Test-retest reliability provides a good correlation. Some instruments show a ceiling effect. According to the assessment, the SF-36, SF-6D, EQ-5D, SF-12 and PedsQoL instruments are considered as established instruments. Further validation testing is needed to provide and support the measurement of subsequent quality of life (HRQoL) instruments.

Malaysia aims to be one of the developed nations by year 2020; therefore, it is crucial to gauge the quality of working life in a parallel manner using a well-established Work-Related Quality of Life (WRQoL) Scale. The goal of this study is to describe the validity and psychometric properties of the Malay WRQoL Scale in Malaysian population.<br />A total of 572 respondents took part in this cross-sectional study giving a 97% response rate. The reliability of the Malay WRQoL Scale was assessed using the test retest reliability analysis after a 2-week period. Both the interclass correlation (ICC) and Cronbach’s alpha were within acceptable levels. However in the validity analysis, the exploratory factor analysis only revealed 5 factors instead of 6 in the original scale.<br />The Malay WRQoL scale has demonstrated to have the appropriate psychometric properties and can therefore be used in Malaysia to assess the quality of working life.
