Determining the psychometric properties of a novel questionnaire to measure “preparedness for the future” (Prep FQ)

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.

Abstract Background and objective Quality of life (QoL) is a multi-dimensional concept and its assessment is one of important themes of care for older people. Assessing QoL in older people needs specific scales. The aim of this study was to culturally adapt and investigate the psychometric properties of the Persian version of brief Older People’s Quality of Life questionnaire (OPQOL-brief) in an Iranian older population. Methods This methodological cross-sectional study was conducted among 525 Persian-speaking older people (aged 60 and over), living in Isfahan, Iran. Translation of the OPQOL-brief questionnaire was performed using forward–backward method. Test–retest reliability was evaluated through Intra Class Correlation (ICC) coefficient and internal consistency by using Cronbach’s α. Construct validity was investigated by using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Latent class analysis (LCA). Criterion, convergent and discriminant validities were also assessed. Results Persian version of the OPQOL-brief showed good test–retest reliability (ICC = 0.842, 95% CI = 0.73–0.91; P < 0.001). Persian OPQOL-brief scale demonstrated high internal consistency (Cronbach’s α = 0.83). It showed good discriminant validity and differentiated old patients from healthy older individuals (P < 0.001). Construct validity based on EFA led to extraction of three dimensions (“socioeconomic”, “emotional”, and “physical” well-being) and the CFA confirmed the adequacy of extracted construct from EFA (CFI = 0.909, PCFI = 0.52, PNFI = 0.5, CMIN/DF = 3.012, and RMSEA = 0.08). LCA classified participants into three classes in terms of QoL level (low (16%), middle (67%), and high (17%)). Criterion validity and convergent validity revealed significant positive correlations between OPQOL-brief and physical and psychological dimensions of the SF-36. Conclusion The Persian version of the OPQOL-brief is a reliable and valid instrument for assessing QoL with applicability in a broad range of older Persian language 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.

The article presents an analysis of the problem of determining disabled-since-childhood adults’ quality of life. We suggested that coping behavior was a factor of high quality of life and subjective well-being. The sample (N=102) included disabled-since-childhood adults’ (N=51) with visual (N=16), hearing (N=18) and mobility disabilities (N=17) and adults with typical development (N=51). The respondents` average age is 37 years. Methods: the brief questionnaire WHOQOL-BREF in the adaptation of the V.M. Bechterev Research Institute; M.V. Sokolova’s Subjective Well-Being Scale; The Ways of Coping Questionnaire (Folkman, Lazarus, adapted by Kryukova T.L., Kuftyak E.V.). The results indicate a sufficiently high quality of life of adults with disabilities regardless of the type of disorders. The links between coping strategies, indicators of quality of life and subjective well-being are described. Distancing, avoidance and positive revaluation strategies make the greatest contribution to the quality of life. We conducted a separate analysis of the determination of the quality of life by coping strategies in groups of people with various disabilities. The results of the study can be used to develop rehabilitation programs and help people with disabilities.

Derek Parfit has famously pointed out that ‘total’ utilitarian views, such as classical hedonistic utilitarianism, lead to the conclusion that, to each population of quite happy persons there corresponds a more extensive population with people living lives just worth living, which is (on the whole) better. In particular, for any possible population of at least ten billion people, all with a very high quality of life, there must be some much larger imaginable population whose existence, if other things are equal, would be better, even though its members have lives that are barely worth living. This world is better if the sum total of well-being is great enough, and it is great enough if only enough sentient beings inhabit it. This conclusion has been considered by Parfit and others to be ‘repugnant’.

SummaryThere has been a growing interest in the quality of life (QoL) of the mentally ill, subsequently a number of instruments to measure QoL have been developed. One of the measures of QoL which has received considerable attention is the Lancashire QoL Profile (LQOLP). The present study investigated test-retest reliability and internal consistency in the Swedish translation of the LQOLP using a cross-sectional sample of 29 inpatients. The results showed that test-retest reliability of subjective life satisfaction in the nine life domains covered by the LQOLP was satisfactory in seven of the domains, and acceptable in two (social relations and religion). Test-retest reliability for total subjective satisfaction score, global well-being, and an interviewer rated QoL were all on a satisfactory level (r > 0.80). The internal consistency and homogeneity of the total subjective QoL scale and the nine life domain subscales was satisfactory except for the social relations scale, where it was somewhat low.

Objective: To test the Brazilian Portuguese velopharyngeal insufficiency (VPI) Effects on Life Outcome (VELO) instrument for reliability and validity. Design: Cross-sectional methodological study. Setting: Tertiary craniofacial medical center. Participants: Participants with VPI (VPI group, n = 60), with cleft and without VPI (no VPI/cleft group, n = 60), and with no cleft nor VPI (no VPI/no cleft group, n = 60) and their parents (n = 180). Interventions: All patients with VPI 8+ years old and their parents completed the Brazilian–Portuguese VELO instrument and other questionnaires (Pediatric Quality of Life Inventory4.0, PedsQL4.0; Pediatric Voice-Related Quality of Life, PVRQOL; and Intelligibility in Context Scale, ICS) at baseline; patients with VPI and their parents completed the VELO instrument again 2 weeks later. Main Outcome Measures: The VELO instrument was tested for internal consistency, test–retest reliability, discriminant validity (participants with VPI against participants with no VPI), concurrent validity against other questionnaires, criterion validity against hypernasality severity, and construct validity against nasal air emission and overall velopharyngeal competence (speech construct) and velopharyngeal gap (anatomic construct). Results: The VELO had excellent internal consistency (Cronbach α 0.99 for parents and 0.98 for participants with VPI) and test–retest reliability (all intraclass correlation coefficient > 0.87). The VELO discriminated well between VPI group and unaffected groups (all P < .05). The VELO was significantly correlated with the PedsQL4.0, PVRQOL, and ICS (– r > 0.75; P < .001). The VELO met criterion validity, speech construct validity, and anatomic construct validity ( r > 0.7; P < .001). Conclusions: The Brazilian-Portuguese VELO instrument demonstrated reliability (internal consistency and test–retest) and validity (discriminant, concurrent, criterion, and construct).

18527 Background: ZEST is a placebo-controlled trial of sertraline for people with advanced cancer who feel depressed, anxious or tired but do not have a clear indication for antidepressants. We describe here the aspects of quality of life (QL) rated most troublesome at baseline by the first 150 subjects. Methods: Subjects completed a battery of QL questionnaires including the CES-D, HADS, FACT-G, FACT-Fatigue, and the Patient Disease and Treatment Assessment Form (Pt DATA Form). The Pt DATA Form assesses pertinent symptoms and concerns using 40 single items with a uniform response scale from 0 (no trouble at all) to 10 (worst I can imagine). Test-retest reliability was assessed with the intraclass correlation coefficient (ICC). Convergent validity was assessed by testing correlations between single items from the PT DATA Form and the corresponding, validated, multi-item scales. Results: The median age was 66 (IQR 59 to 73); median Karnofsky Perfomance Status was 80 (IQR 70 to 90); 63% were male; commonest primaries were colorectal (17%), lung (16%), prostate, (14%), breast (13%), and gynaecologic (10%). The aspects rated worst (mean score, proportion scoring >3) were: Fatigue (5.5, 90%), Problems with sex (4.1, 51%), Trouble sleeping (3.6, 49%), Drowsiness (3.5, 54%), Not feeling myself (3.5, 51%), Pain (3.4, 45%), Shortness of breath (3.4, 47%), Problems doing what I wanted (3.1, 45%), Anxiety (3.0, 40%), Depression (2.7, 36%), Dry mouth (2.7, 38%), Trouble concentrating (2.7, 30%), Irritability (2.6, 32%), Altered sense of taste (2.5, 34%), Difficulty walking (2.4, 32%), and Constipation (2.1, 24%). Mean scores were higher in men than women for Problems with sex (5.0 v 2.4, p < 0.001); and, in subjects aged 65 or younger for Hair loss (2.4 v 1.1, p = .01). There were no other significant differences by gender or age. Correlations supported the validity of the single item scales for depression, anxiety, fatigue; and for physical, emotional and overall well-being. The test-retest reliability of the Pt DATA Form was good (ICC >0.5 for 34 of 40 items). Conclusions: Pertinent aspects of QL were validly measured with single item scales. Insomnia, dry mouth, altered sense of taste and irritability were more troublesome than many other, better studied symptoms. No significant financial relationships to disclose.

Persian Translation

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.

Background:Most amputees live with their prostheses for a long time. Therefore, quality of life is an important outcome for lower limb amputees.Objective:To translate the Prosthesis Evaluation Questionnaire (PEQ) and evaluate psychometric properties.Study Design:Methodological research.Methods:Lower limb amputees responded to electronic versions of the PEQ and SF-36v2 at baseline (n=64), after two weeks (n=51), and after 12 weeks (n=50). Reliability was assessed using Cronbach’s alpha and intraclass correlation coefficient (ICC) analyses of the baseline and two weeks test-retest data. Estimates for standard error of measurement (SEM) were calculated based on reliability estimates. Construct validity was evaluated by testing using hypotheses testing.Results:Reliability estimates (ICC/Cronbach’s alpha) for the nine subscales were: Social Burden (0.85/0.76), Appearance (0.85/0.72), Residual Limb Health (0.80/0.69), Well-Being (0.78/0.90), Utility (0.76/0.89), Frustration (0.74/0.90), Perceived Response (0.62/0.80), Ambulation (0.61/0.94), Sounds (0.51/0.65). Construct validity was supported in three out of four subscales evaluated.Conclusions:The subscales Social Burden, Appearance, Well-Being, Utility and Frustration had consistent high reliability, supporting their use in assessing the prosthesis related quality of life in lower limb amputees. Results were mixed on three other scales (Residual Limb Health, Perceived Response, and Ambulation), while one scale, Sounds, had consistent low reliability.Clinical relevanceFor the first time a patient reported disease specific quality of life measure for lower limb amputees is available in Danish. Health care providers can now identify patients with reduced quality of life and measure treatment and rehabilitation effects over time.

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.
