St George's Respiratory Questionnaire

Tuberculosis (TB) is one of the disease as the highest contributor to the disease burden in Indonesia. Tuberculosis can affect the patients’ quality of life, such as psychological, physical, and social functioning. St. George's Respiratory Questionnaire (SGRQ) is a special instrument which was widely used to measure the patients’ quality of life with respiratory disease. The objective of this study was to validate the Indonesian version of the SGRQ as instrument to collect data. A descriptive cross section design with 61 subjects was conducted at the Pulmonary Clinics and Primary Health Centers in the region of Yogyakarta within 3 months. The validation process included the known group validity, convergent and discriminant validity and factor analysis. There were 14 items question numbers which did not meet the criteria for convergent validity and 9 items which did not meet the criteria for discriminant validity. Known group validity analysis on gender showed that of the three domains of SGRQ, the activity domain gave statistically significant result. The factor analysis showed the result of Kaiser Meyer Olkin analysis (KMO) was less than 0.5. With a few modifications, the Indonesian version of SGRQ is valid and reliable for measuring quality of life in tuberculosis patients.

Disease Specific

Quality of life (QoL) is discussed as an additional outcome measure in multiple sclerosis (MS). However, few questionnaires assessing disease specific QoL in MS have been published. On the basis of the literature and interviews with clinicians and MS patients, we have developed a disease specific QoL instrument and validated it in a broad range of patients with MS. In this study, a heterogeneous sample of n=237 MS patients completed the newly developed Hamburg Quality of Life Questionnaire in Multiple Sclerosis (HAQUAMS, in German language) and a battery of already validated questionnaires. They further underwent neurological scoring and objective tests. By these means, we investigated its validity, appropriateness, internal consistency, and retest reliability. Internal consistency and retest coefficients were high and satisfied psychometric standards. Convergent and discriminant validity was supported by direction, magnitude and pattern of correlations with other health measures. HAQUAMS subscales and its total score distinguished between patient groups of varied disease severity, cognitive impairment, and affective symptomatology. No floor or ceiling effects were found in either of the HAQUAMS subscales. The HAQUAMS is a reliable, valid and appropriate instrument for QoL assessment in multiple sclerosis. Data of responsiveness are currently being obtained.

Background: There are large number of post menopausal patients in India deserving more care and attention than is given at present.MRS questionnaire in Hindi (MRS-H), a translated and validated version of original MRS Scale (MRS-E), self assessed by patients in their own native language. This tool can be used to assess and document current quality of life as well as improvement with treatment of severe post menopausal symptoms, in Indian population.Methods: 30 bilingual English and Hindi speaking postmenopausal patients were recruited for this study.MRS Questionnaire has 11 questions covering somatic, pschycological and genitourinary symptoms of menopause. The scoring system is simple. Hindi translation of MRS Questionare was done from English (MRS-E) to Hindi (MRS-H) by 4 independent translations using standard protocol. The MRS-H was tested for internal validity and also compared with MRS - E.Results: Quality of life is a subjective perception modified by the cultural habitat in which one lives. MRS-H showed high validity and good co-relation with MRS-E. The MRS-H possessed good convergent and discriminant validity. MRS-H showed anICC (Intraclass coefficient) was more than 0.5 and cronbach alpha more than0.5. There was found to be strong correlation between MRS-E and MRS-H questionnaire with all correlation value above 0.7.Conclusions: The authors recommend the use of the self assessed MRS-H in Hindi should be used to assess menopausal complaints and relief with treatment in India.

Abstract Background and Objective: There is no comprehensive instrument for the assessment of postpartum quality of life (QOL). This study was conducted to develop the Maternal Postpartum Quality of Life Instrument (MPQOLI) and assess its psychometric properties.Materials and Methods: This methodological study was conducted in 2019–2020 using an exploratory sequential mixed-method design. A qualitative study and a literature review were conducted to generate MPQOLI items. Through purposeful sampling, 590 postpartum women were recruited to respond the instrument. Face and content validity were assessed qualitatively and quantitatively and construct validity was assessed through exploratory and confirmatory factor analyses and convergent and discriminant validity assessments. Reliability was also assessed through different methods, including Cronbach’s alpha and McDonald’s Omega.Results: Eight items were deleted in content validity assessments and eighteen items were deleted in item analysis. Participants responded the 31-item MPQOLI. During exploratory factor analysis, fifteen items were deleted and the remaining sixteen items were loaded on five factors labeled perceived support, sexual relationship, bonding with newborn, breastfeeding and newborn care, and satisfaction with postpartum transition. These five factors explained 53.26% of the total variance. Confirmatory factor analysis confirmed the five-factor structure of MPQOLI with a CMIN/DF of 2.192, an RMSEA of 0.057, a χ2 of 206.087, a PCFI of 0.738, a PNFI of 0.705, a CFI of 0.942, and an IFI of 0.943. Average variance extracted was more than 0.5 and more than maximum shared squared variance, confirming convergent and discriminant validity, respectively. Reliability was also confirmed with Cronbach’s alpha values of 0.70–0.907 and an intraclass correlation coefficient of 0.919.Conclusion: The sixteen-item MPQOLI is a valid and reliable instrument for postpartum QOL assessment. It includes items on the different aspects of postpartum QOL and can be used for the early diagnosis of impaired postpartum QOL. Further studies are needed to assess the psychometric properties of MPQOLI in different cultures and communities.

BACKGROUND Although the quality of life (QoL) plays an important role in treatment decision making and clinical management of mycosis fungoides (MF) or Sézary syndrome (SS) subtypes of cutaneous T-cell lymphomas (MF/SS-CTCLs), an MF- or SS-specific measure of QoL does not exist. OBJECTIVE The objective of this research was to develop and validate the first QoL instrument for MF/SS-CTCL using a patient-centered approach. METHODS A conceptual framework for the MF/SS-CTCL QoL was developed through a literature review and interviews with key opinion leaders. Concept elicitation with patients was utilized to refine the conceptual model and generate preliminary items. The items were then revised based on qualitative and quantitative feedback obtained through cognitive debriefing surveys and interviews with patients. Next, participants (N=126) completed the preliminary MF/SS-CTCL QoL and a comparator measure of health-related QoL (Skindex-29) through the PatientsLikeMe Open Research Exchange. The MF/SS-CTCL QoL was completed again 5 days later by 66 participants for the purposes of evaluating test-retest reliability. The MF/SS-CTCL QoL was finalized based on results from an empirical evaluation, which included both classical and modern test theory approaches. Specifically, this included evaluation of (1) the optimal item response theory measurement model; (2) item fit; (3) unidimensionality; (4) rating scale performance; (5) reliability; (6) test information (precision); (7) person-to-item map; (8) convergent and discriminant validity; and (9) presence of bias via differential item function. RESULTS Results from the comprehensive psychometric evaluation utilizing a Rasch-Grouped Rating Scale model yielded a final 12-item instrument. The rating scale functioned as expected, and the instrument exhibited adequate person reliability (.87), good to excellent test-retest reliability (r=.89, P<.001), high levels of measurement precision, and good person-to-item targeting. The correlation between the MF/SS-CTCL QoL and the Skindex-29 (r=.852, P<.001) was significantly greater than the correlation between the MF/SS-CTCL QoL and syndrome stage (r=.260, P<.001), providing support for convergent and discriminant validity. Items did not show significant bias based on gender, age, or race. Rasch scores were converted to scaled scores with qualitative descriptive categories for ease of interpretation. CONCLUSIONS Empirical evaluation demonstrated strong evidence of excellent psychometric properties. Utilizing a patient-centered measure development approach ensures that this QoL instrument captures the information that is most meaningful and clinically relevant to patients.
