A translation and preliminary validation of the Dutch Wound-QoL questionnaire

Abstract BackgroundChronic wounds have a major impact on patients’ health-related quality of life (HRQoL). Therefore, measuring HRQoL is an indispensable part of the treatment of patients with chronic wounds. The aim of this study was to translate and validate the Wound-QoL, a wound-specific HRQoL questionnaire, in a Dutch population. MethodsThe Wound-QoL was translated into Dutch according to the international standards. Patients with chronic wounds were asked to complete questionnaires at baseline (T0) and after 6 weeks (T1), including Wound-QoL, EQ-5D-3L (a generic questionnaire to measure HRQoL) and a visual analogue scale (VAS) measuring wound pain. If patients were not able to complete the questionnaire by themselves, it was read out to them by a nurse. Further data were obtained from medical records.ResultsOf the 120 patients included, 64 (53.3%) completed the questionnaire by themselves. To 55 patients (45.8%), the questionnaire was read out. The internal consistency of the Wound-QoL global score was high at both time points (T0: Cronbach’s α=0.89, T1: Cronbach’s α=0.92). The item selectivity for global score ranged from r=0.25 to r=0.77 at T0 and from r=0.40 to r=0.79 at T1. Overall, the self-completion and read-out subgroups showed similar internal consistency and item selectivity scores. With regard to convergent validity, significant correlations were found between Wound-QoL and EQ-5D-3L (T0: r=-0.45, p<0.001, T1: r=-0.50, p<0.001) as well as between Wound-QoL and pain VAS (T0: r=0.23, p=0.012, T1: r=0.37, p=0.001) at both time points. Responsiveness analyses showed significant correlations between changes in Wound-QoL and changes in EQ-5D-3L (r=-0.37, p<0.001), pain VAS (r=0.24, p=0.044) and wound size (r=0.24, p=0.013). The self-completion and read-out subgroups showed differences in convergent validity and responsiveness. ConclusionsThe results indicate that the Dutch version of the Wound-QoL has positive psychometric properties. However, more research is needed to further explore the differences between self-completed and read-out questionnaires.

BACKGROUND Engagement emerges as a predictor for the effectiveness of digital health interventions. However, a shared understanding of engagement is missing. Therefore, a new scale has been developed that proposes a clear definition and creates a tool to measure it. The TWente Engagement with Ehealth Technologies Scale (TWEETS) is based on a systematic review and interviews with engaged health app users. It defines engagement as a combination of behavior, cognition, and affect. OBJECTIVE This paper aims to evaluate the psychometric properties of the TWEETS. In addition, a comparison is made with the experiential part of the Digital Behavior Change Intervention Engagement Scale (DBCI-ES-Ex), a scale that showed some issues in previous psychometric analyses. METHODS In this study, 288 participants were asked to use any step counter app on their smartphones for 2 weeks. They completed online questionnaires at 4 time points: T0=baseline, T1=after 1 day, T2=1 week, and T3=2 weeks. At T0, demographics and personality (conscientiousness and intellect/imagination) were assessed; at T1-T3, engagement, involvement, enjoyment, subjective usage, and perceived behavior change were included as measures that are theoretically related to our definition of engagement. Analyses focused on internal consistency, reliability, and the convergent, divergent, and predictive validity of both engagement scales. Convergent validity was assessed by correlating the engagement scales with involvement, enjoyment, and subjective usage; divergent validity was assessed by correlating the engagement scales with personality; and predictive validity was assessed by regression analyses using engagement to predict perceived behavior change at later time points. RESULTS The Cronbach alpha values of the TWEETS were .86, .86, and .87 on T1, T2, and T3, respectively. Exploratory factor analyses indicated that a 1-factor structure best fits the data. The TWEETS is moderately to strongly correlated with involvement and enjoyment (theoretically related to cognitive and affective engagement, respectively; <i>P</i><.001). Correlations between the TWEETS and frequency of use were nonsignificant or small, and differences between adherers and nonadherers on the TWEETS were significant (<i>P</i><.001). Correlations between personality and the TWEETS were nonsignificant. The TWEETS at T1 was predictive of perceived behavior change at T3, with an explained variance of 16%. The psychometric properties of the TWEETS and the DBCI-ES-Ex seemed comparable in some aspects (eg, internal consistency), and in other aspects, the TWEETS seemed somewhat superior (divergent and predictive validity). CONCLUSIONS The TWEETS performs quite well as an engagement measure with high internal consistency, reasonable test-retest reliability and convergent validity, good divergent validity, and reasonable predictive validity. As the psychometric quality of a scale is a reflection of how closely a scale matches the conceptualization of a concept, this paper is also an attempt to conceptualize and define engagement as a unique concept, providing a first step toward an acceptable standard of defining and measuring engagement.

Background: The Multiple Sclerosis Spasticity Scale 88 (MSSS-88) is designed to capture the patient experience and impact of spasticity, but there is limited evaluation against clinician-rated measures of spasticity. Objective: To evaluate the convergent validity and responsiveness of the MSSS-88. Design: Longitudinal study. Setting: University Laboratory. Subjects: Thirty-four people with multiple sclerosis. Methods: People with multiple sclerosis (MS; n = 34) completed the self-reported 12-item Multiple Sclerosis Walking Scale, Multiple Sclerosis Spasticity Scale, Barthel Index alongside the clinician-rated Ashworth Scale, and a laboratory-based measure of ankle spasticity. Spasticity measure responsiveness was evaluated in 20 participants at two time points, an average of 8.75 ± 3.8 months apart. Results: In people with MS (mean age 55.1 ± 8.1 years; Expanded Disability Scale range 4.5-7.0), spasticity symptom specific subscales of the MSSS-88 (stiffness and spasms) showed strong and significant correlations with the clinician-rated Ashworth Scale ( r = 0.52-0.53; P < .01). Responsiveness of the MSSS-88 was comparable to a laboratory-based measure of ankle spasticity. Conclusions: Our findings lend additional support to the convergent validity of this measure.

Efficacy Measures

Background:Self-efficacy is a consistent correlate of physical activity, but most self-efficacy measures have not been validated in diverse populations. This study examined the construct, criterion-related, and convergent validity and internal consistency of the Self-Efficacy for Exercise Questionnaire.Methods:African American and Caucasian adults (N = 1919) from two adjacent counties in South Carolina were identified through a list-assisted random digit-dialed telephone survey. Psychometric properties of the measure were assessed by gender, race, age, education, and body weight subgroups.Results:Across all subgroups, a single-factor solution explained 93 to 98% of the common variance in an exploratory factor analysis, and all 14 items had factor loadings exceeding 0.40. Higher exercise self-efficacy was significantly associated with greater physical activity, younger age, male gender, higher education, and lower body weight, as predicted. Internal consistency was high for all subgroups (α = 0.90 to 0.94).Conclusion:The Self-Efficacy for Exercise Questionnaire appears to be a valid and reliable measure for use with diverse populations.

Abstract Background: Body image can be defined as individual perception of own body and related behaviors. Body dissatisfaction may lead to low self-esteem, depression and anxiety. Body image can be evaluated and quantified. Among various number of instruments assessing body image, there are: Body Shape Questionnaire-34 (BSQ-34) and Functionality Appreciation Scale (FAS). The aim of this study was to translate and validate the Polish version of both: BSQ-34 and FAS. Methods: Both, forward and backward translations of the original English versions of BSQ-34 and FAS questionnaires was performed in accordance with international standards. The validation of BSQ-34 was conducted on 89 and FAS on 103 individuals. They completed the questionnaires twice with 3-6 days interval. The subjects also filled the Polish versions of BIQLI (Body Image Quality of Life Inventory) and BAS-2 (Body Appreciation Scale-2) for convergent validity procedure. Results: The Polish version of both BSQ-34 and FAS demonstrated very good and good internal consistency and reproducibility. Convergent validity indicated a moderate relationship between BSQ-34 and BIQLI, and strong correlation between FAS and BAS-2. Conclusions: To conclude the Polish version of both BSQ-34 and FAS questionnaire showed sufficient internal consistency and reliability. They can be used in clinical practice in subjects speaking Polish language. Trial registration: Wroclaw Medical University EC approval no: 2/06/20

Analysis of the responses of 139 male and 83 female Lithuanian 12-14 year-olds to a translation of the Self-Description Questionnaire-1 (SDQ-1; Marsh, 1988 ) supported the internal consistency and factor structure of this instrument. Some evidence of a “positivity” response bias was found, however. Comparison of the Lithuanian responses to those of like-aged Australian, Chinese, Filipino, Nepalese, and Nigerian children indicated the Lithuanians tended to report rather lower self-esteem. The Lithuanian males also tended to report lower self-esteem than their female peers. Interpretation of the results are considered in terms of reactions to the recent upheavals in Eastern Europe, stable cultural dimensions, and possible cultural and gender biases in the items of the SDQ-1.

Objective: There are presently no instruments available in German language to assess the therapeutic relationship in psychiatric care. This study validates the German version of the Scale to Assess the Therapeutic Relationship in Community Mental Health Care (D-STAR). Method: 460 persons with severe mental illness and 154 clinicians who had participated in a multicenter RCT testing a discharge planning intervention completed the D-STAR. Psychometric properties were established via item analysis, analyses of missing values, internal consistency, and confirmatory factor analysis. Furthermore, convergent validity was scrutinized via calculating correlations of the D-STAR scales with two measures of treatment satisfaction. Results: As in the original English version, fit indices of a 3-factor model of the therapeutic relationship were only moderate. However, the feasibility and internal consistency of the D-STAR was good, and correlations with other measures suggested reasonable convergent validity. Conclusions: The psychometric properties of the D-STAR are acceptable. Its use can be recommended in German-speaking countries to assess the therapeutic relationship in both routine care and research.

Objective: To develop and validate a Thai version of the Wisconsin Quality of Life (TH WISQoL) Questionnaire. Materials and Methods: The authors developed the TH WISQoL Questionnaire based on a standard multi-step process. Subsequently, the authors recruited patients with kidney stone and requested them to complete the TH WISQoL and a validated Thai version of the 36-Item Short Form Survey (TH SF-36). The authors calculated the internal consistency and interdomain correlation of TH WISQoL and compared the convergent validity between the two instruments. Results: Thirty kidney stone patients completed the TH WISQoL and the TH SF-36. The TH WISQoL showed acceptable internal consistency for all domains (Cronbach’s alpha 0.768 to 0.909). Interdomain correlation was high for most domains (r=0.698 to 0.779), except for the correlation between Vitality and Disease domains, which showed a moderate correlation (r=0.575). For convergent validity, TH WISQoL demonstrated a good overall correlation to TH SF-36, (r=0.796, p<0.05). Conclusion: The TH WISQoL is valid and reliable for evaluating the quality of life of Thai patients with kidney stone. A further large-scale multi-center study is warranted to confirm its applicability in Thailand. Keywords: Quality of life, Kidney stone, Validation, Outcome measurement
