Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL): Reliability and Validity

Background Patients may develop primary (congenital) or secondary (acquired) lymphedema, causing significant physical and psychosocial problems. To plan treatment for lymphedema and monitor a patient's progress, swelling, and problems in functioning associated with lymphedema development should be assessed at baseline and follow-up. Objective The purpose of this study was to investigate the reliability (test-retest, internal consistency, and measurement variability) and validity (content and construct) of data obtained with the Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL). Design This was a multicenter, cross-sectional study. Methods The Lymph-ICF-LL is a descriptive, evaluative tool containing 28 questions about impairments in function, activity limitations, and participation restrictions in patients with lower limb lymphedema. The questionnaire has 5 domains: physical function, mental function, general tasks/household activities, mobility activities, and life domains/social life. The reliability and validity of the Lymph-ICF-LL were examined in 30 participants with objective lower limb lymphedema. Results Intraclass correlation coefficients for test-retest reliability ranged from .69 to .94, and Cronbach alpha coefficients for internal consistency ranged from .82 to .97. Measurement variability was acceptable (standard error of measurement=5.9–12.6). Content validity was good because all questions were understandable for 93% of participants, the scoring system (visual analog scale) was clear, and the questionnaire was comprehensive for 90% of participants. Construct validity was good. All hypotheses for assessing convergent validity and divergent validity were accepted. Limitations The known-groups validity and responsiveness of the Dutch Lymph-ICF-LL and the cross-cultural validity of the English version of the Lymph-ICF-LL were not investigated. Conclusions The Lymph-ICF-LL is a Dutch questionnaire with evidence of reliability and validity for assessing impairments in function, activity limitations, and participation restrictions in people with primary or secondary lower limb lymphedema.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P < 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Background: The Podiatric Health Questionnaire (PHQ) is a health-related questionnaire consisting of six questions designed for measuring foot health status. To date, the PHQ has only been validated in the English-language version. Thus, this study aimed to perform the Spanish translation and test–retest procedures of the PHQ (PHQ-S). Method: The forward/backward translation and test–retest reliability methods were applied from English to Spanish languages. Regarding the total score for each domain, internal consistency and reliability were determined by the Cronbach α and intraclass correlation coefficient (ICC) with a confidence interval (CI) of 95%. Results: High internal consistency was shown for the six domains: (1) walking with a Cronbach α of 0.97; (2) hygiene and nail care with 0.93 and 093, respectively; (3) foot pain with 0.91; (4) worry and concern domain with 0.904; (5) quality of life with 0.87; and (6) the self-perception of how their feet are feeling measured by a visual analogic scale with 0.92. Excellent test–retest reliability (ICC = 0.99 (95% CI = 0.96–0.98)) was shown for the total score. Conclusions: The PHQ-S was shown to be a valid and reliable tool for an acceptable use in the Spanish population.

Abstract Background Depression in patients with infertility often goes undiagnosed and untreated. The Patient Health Questionnaire-9 (PHQ-9) and its ultra-brief version (i.e. PHQ-2) are widely used measures of depressive symptoms. These scales have not been validated in patients with infertility. The aim of the present study was to examine the reliability and validity of the PHQ-9 and PHQ-2 in patients with infertility. Methods In this cross-sectional study, a total of 539 patients with infertility from a referral infertility clinic in Tehran, Iran completed the PHQ-9, along with other relevant scales: the WHO-five Well-being Index (WHO-5), the Hospital Anxiety and Depression Scale (HADS), and the Generalized Anxiety Disorder-7 (GAD-7). Factor structure and internal consistency of PHQ-9 were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was evaluated by relationship with WHO-5, HADS and GAD-7. Results The mean total PHQ-9 and PHQ-2 scores were 8.47 ± 6.17 and 2.42 ± 1.86, respectively, and using a cut-off value of 10 (for PHQ-9) and 3 (for PHQ-2), the prevalence of depressive symptoms was 38.6 and 43.6%, respectively. The Cronbach’s alphas for PHQ-9 and PHQ-2 were, respectively, 0.851 and 0.767, indicating good internal consistency. The CFA results confirmed the one-factor model of the PHQ-9 (χ2/df = 4.29; CFI = 0.98; RMSEA = 0.078 and SRMR = 0.044). Both PHQ-9 and PHQ-2 showed moderate to strong correlation with the measures of WHO-5, HADS-depression, HADS-anxiety, and the GAD-7, confirming convergent validity. In univariate analysis, female sex, long infertility duration, and unsuccessful treatment were significantly associated with depression symptoms. Conclusion Both PHQ-9 and PHQ-2 are brief and easy to use measures of depressive symptoms with good psychometric properties that appear suitable for routine use in patients with infertility.

Purpose: The present study was designed to carry out an Italian translation of the Constant–Murley Score (CMS-IT) and, subsequently, evaluate its reliability and validity. Methods: This study included adults diagnosed with any type of clinical shoulder dysfunction who could read and respond to the questionnaires. Those individuals who underwent surgeries of any kind on the affected shoulder during the previous 12 months and individuals with shoulder instabilities were excluded. All of the participants were evaluated by two operators, and the CMS-IT, Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and visual analog scale (VAS) were administered. The internal consistency was evaluated using Cronbach’s α, whereas the intra-rater and inter-rater reliabilities were evaluated using the intraclass correlation coefficient (ICC). The validity of the construction was evaluated using Pearson’s correlation coefficient between the scores of the administered scales. Results: A population of 72 individuals participated in this study. The internal consistency of the CMS-IT showed a value of 0.81. The ICC values showed that inter- and intra-rater reliability were 0.994 and 0.963, respectively. CMS-IT is inversely correlated with the VAS (−0.55) and DASH (−0.47) scales. Conclusions: This study revealed that the CMS-IT contained good internal consistency and good reliability. The results suggested that the CMS-IT questionnaire is a reliable and valid tool for assessing the shoulder dysfunctions of the Italian population, and it deserves broad applications in both clinical practice and research contexts. The scale can also be used as an alternative to the current “gold standard” VAS and DASH.
