Abstract Introduction The Diabetes Health Profile (DHP‐18), structured in three dimensions (psychological distress (PD), barriers to activity (BA) and disinhibited eating (DE)), assesses the psychological and behavioural burden of living with type 2 diabetes. The objectives were to adapt the DHP‐18 linguistically and culturally for use with patients with type 2 DM in Ecuador, and to evaluate its psychometric properties. Methods Participants were recruited using purposive sampling through patient clubs at primary health centres in Quito, Ecuador. The DHP-18 validation consisted in the linguistic validation made by two Ecuadorian doctors and eight patient interviews. And in the psychometric validation, where participants provided clinical and sociodemographic data and responded to the SF-12v2 health survey and the linguistically and culturally adapted version of the DHP-18. The original measurement model was evaluated with confirmatory factor analysis (CFA). Reliability was assessed through internal consistency using Cronbach’s alpha and test–retest reproducibility by administering DHP-18 in a random subgroup of the participants two weeks after (n = 75) using intraclass correlation coefficient (ICC). Convergent validity was assessed by establishing previous hypotheses of the expected correlations with the SF12v2 using Spearman’s coefficient. Results Firstly, the DHP-18 was linguistically and culturally adapted. Secondly, in the psychometric validation, we included 146 participants, 58.2% female, the mean age was 56.8 and 31% had diabetes complications. The CFA indicated a good fit to the original three factor model (χ2 (132) = 162.738, p < 0.001; CFI = 0.990; TLI = 0.989; SRMR = 0.086 and RMSEA = 0.040. The BA dimension showed the lowest standardized factorial loads (λ) (ranging from 0.21 to 0.77), while λ ranged from 0.57 to 0.89 and from 0.46 to 0.73, for the PD and DE dimensions respectively. Cronbach’s alphas were 0.81, 0.63 and 0.74 and ICCs 0.70, 0.57 and 0.62 for PD, BA and DE, respectively. Regarding convergent validity, we observed weaker correlations than expected between DHP-18 dimensions and SF-12v2 dimensions (r > −0.40 in two of three hypotheses). Conclusions The original three factor model showed good fit to the data. Although reliability parameters were adequate for PD and DE dimensions, the BA presented lower internal consistency and future analysis should verify the applicability and cultural equivalence of some of the items of this dimension to Ecuador.

ObjectiveThe Diabetes Health Profile-18 (DHP-18) was developed to measure disease-specific health-related quality of life. It has been translated into Norwegian but remains invalidated. The purpose of this paper was to examine the psychometric properties of the Norwegian DHP-18.Research design and methodsParticipants with type 1 diabetes were recruited from three outpatient clinics in Norway. Clinical and sociodemographic data were collected, and participants completed the DHP-18 and the Short-Form 36 (SF-36). Descriptive analysis, frequencies, t-tests and the chi-squared tests were used. Principal axis factoring (PAF) and confirmatory factor analysis (CFA) were used. Convergent validity was tested using Spearman’s correlation between the DHP-18 and SF-36. Reliability was tested using Cronbach’s alpha and intraclass correlation coefficient.ResultsIn total, 288 patients were included. No floor and ceiling effects were found. A forced PAF analysis revealed that three questions had an eigenvalue below 0.40. In the unforced PAF analysis, one question loaded below 0.40, while three questions loaded into a fourth factor. The correlation between the DHP-18 and SF-36 dimensions was low to moderate. Problematic internal consistency was observed for the disinhibited eating dimension in the forced PAF and in the suggested fourth dimension in the unforced PAF. CFA revealed poor fit. The test–retest reliability displayed good to excellent values, but responsiveness was limited.ConclusionsProblematic issues were identified regarding factor structure, item loadings, internal consistency and responsiveness. Further evaluation of responsiveness is particularly recommended, and using a revised 14-item DHP version is suggested.

This study examined the psychometric properties of the Chinese version of the Personal Diabetes Questionnaire (C-PDQ). The PDQ was translated into Chinese using a forward and backward translation approach. After being reviewed by an expert panel, the C-PDQ was administered to a convenience sample of 346 adults with Type 2 diabetes. The Chinese version of the Summary of Diabetes Self-Care Activities (C-SDSCA) was also administered. The results of the exploratory factor analysis revealed a one-factor structure for the Diet Knowledge, Decision-Making, and Eating Problems subscales and a two-factor structure for the barriers-related subscales. The criterion and convergent validity were supported by significant correlations of the subscales of the C-PDQ with the glycated hemoglobin values and the parallel subscales in the C-SDSCA, respectively. The C-PDQ subscales also showed acceptable internal consistency (α = .61–.89) and excellent test–retest reliability (intraclass correlation coefficients: .73–.96). The results provide preliminary support for the reliability and validity of the C-PDQ. This comprehensive, patient-centered instrument could be useful to identify the needs, concerns, and priorities of Chinese patients with type 2 diabetes.

AbstractObjectiveTo assess the perceived outcomes associated with diet/food intake in the general adult population.Design and subjectsThe Food Benefits Assessment (FBA©) questionnaire was developed from subjects’ verbatim transcripts (n 18) and after comprehension tests (n 5). Normal-weight (n 130) and overweight (n 67) subjects then completed the final questionnaire twice, 7 d apart. Psychometric properties were assessed, including construct validity by principal components analysis (PCA), concurrent validity (Spearman coefficient) with the Short Form-36 scale (SF-36), known-group validity by comparing FBA dimension scores according to lifestyle and clinical variables, internal consistency reliability (Cronbach’s α) and test–retest reproducibility in stable subjects over 1 week (intraclass correlation coefficient, ICC).ResultsPCA and Multitrait analysis confirmed the final version of the FBA comprising forty-one items split into seven dimensions (vitality; digestive comfort; physical appearance; well-being; snacking; disease prevention; aesthetics). All dimensions displayed good item convergent validity (0·44 to 0·80), good concurrent validity (highest correlation between well-being dimension of FBA and mental health scale of SF-36, r = 0·83) and good known-group validity and reproducibility (ICC ≥ 0·76); internal consistency reliability was good to excellent (Cronbach’s α = 0·79 to 0·91).ConclusionThe FBA is the first valid and reliable questionnaire that allows the assessment of diet effects and impact as perceived by subjects. It is a good candidate in the nutrition field for further use in specific population settings and with a particular food or daily diet. Linguistically validated English (UK and US) and German versions of the questionnaire are available.

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 &lt; 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.

The field of family business research is advanced by further examining the validity and reliability of Klein, Astrachan, and Smyrnios’s Family Influence on Power, Experience, and Culture Scale. Data from 831 family businesses are analyzed to assess the measure’s construct validity using exploratory and confirmatory techniques. The hypothesized three-factor model emerged to include culture, power, and experience. Extending the previous effort, the measure’s convergent validity was tested by assessing differences between the measure’s scores and the desires of the senior generation and the commitment of the next generation. Results support an initial level of convergent validity.

The aim of this study was to examine the psychometric properties of an adapted version of the Quantitative Checklist for Autism in Toddlers (Q-CHAT), an early screening tool that quantifies autistic traits dimensionally, in a community sample of Chilean children aged 18-24 months. An intentional non-probabilistic sampling was used. All primary caregivers of children aged 18-24 months who attended health check-up at four primary care clinics in Chile's Araucanía region during the study period were invited to participate. One hundred and eighty-eight toddlers were screened. Evidence of construct validity was determined through Exploratory Factor Analysis (EFA), evidence of convergent validity with the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F), and evidence of reliability through internal consistency and test-retest. The EFA showed a two-factor structure, which explained 42.2 % of the variance: “Restrictive and Repetitive Patterns” (factor 1), and “Communication and Social Interaction” (factor 2). The total Q-CHAT scores correlated positively and significantly with the total M-CHAT-R/F scores (r=0.59, p&lt;0.01) with a large effect size. Internal consistency was acceptable for the scale in general (α=0.74), acceptable for factor 1 (α = 0.76) and good (α=0.85) for factor 2. Regarding test-retest stability, the intraclass correlation coefficient was good (ICC=0.86, p&lt;0.001). In terms of the factor structure evidenced by the EFA, the two factors are theoretically consistent with the current diagnostic criteria of the DSM-5. The evidence of validity and reliability of Q-CHAT is encouraging when considering its use as an early detection tool in Chile.

Purpose The purpose of the study was to examine the reliability and validity of the Spoken Knowledge in Low Literacy in Diabetes (SKILLD) scale in measuring diabetes knowledge among Hispanics with type 2 diabetes (T2DM). Methods A total of 111 Hispanic participants with T2DM were recruited from clinics and churches in the Southeastern US. The Spanish version of the SKILLD was used. Internal consistency reliability and exploratory factor analysis (EFA) were examined for the Spanish SKILLD. Spearman rank correlations of SKILLD scores with the Summary of Diabetes Self-Care Activities (SDSCA) scores were inspected for evidence of convergent validity along with A1C level and duration of diabetes. Results The average SKILLD score was 35.1% (SD = 23.4%). The correct response for each SKILLD item ranged from 4.5% to 56.8%. The estimated reliability via internal consistency was adequate (Kuder-Richardson 20 = 0.706). EFA of the SKILLD items modestly indicated 1 factor could be retained. Spearman rank correlations of SKILLD scores with diabetes self-care activities were significant and positive for foot self-care. Higher SKILLD scores were significantly correlated with duration of diabetes, using insulin, having a high education level, ever attending a diabetes class, or having a parent with diabetes. Conclusion The Spanish SKILLD showed acceptable reliability and adequate validity in this sample of Hispanics with T2DM. SKILLD scores indicated low diabetes knowledge in this sample. Patient-centered diabetes education tailored to low literacy needs of Hispanics is needed.

BACKGROUND Pain associated with oral problems is one of the most frequent chronic pain of temporomandibular disorders (TMDs). This study was conducted to analyze the psychometric properties of the Indonesian version of the graded chronic pain scale 2.0 (GCPS-ID) in Indonesian patients with TMDs. METHODS The English version of the GCPS version 2.0 was translated and back-translated according to international guidelines. This study conducted from June to December 2016 at the Dental Hospital, Faculty of Dentistry, Universitas Indonesia, and the participants were 202 TMDs patients who had never undergone temporomandibular joint surgery or suffered facial pain for more than 6 months. The evaluation of the GCPS-ID included the internal consistency test, test-retest reliability, and construct validity tests. RESULTS The GCPS-ID had a high internal consistency (Cronbach’s alpha = 0.896). The intraclass correlation coefficient of the pain intensity and the disability score were 0.789 and 0.706, respectively. The convergent validity demonstrated a moderately positive correlation between the GCPS-ID and the Indonesian version of oral health impact profile for TMD for pain (r = 0.595; p<0.001) and disability (r = 0.488; p<0.001). The discriminant validity between GCPS-ID and the subjective patient’s quality of life revealed a weak positive correlation (r = 0.195; p = 0.191). CONCLUSIONS GCPS-ID is a reliable and valid assessment tool for evaluating TMD pain in Indonesia.

ObjectiveTight control of hyperglycemia reduces risk of diabetic retinopathy (DR), but the residual risk remains high. This study aimed to explore relationships between plasma phenylalanine and tyrosine with DR in type 2 diabetes (T2D) and interactions between the two amino acids, and their secondary interaction with renal dysfunction.Research design and methodsWe extracted data of 1032 patients with T2D from tertiary hospital consecutively from May 2015 to August 2016. Binary logistic regression models with restricted cubic spline were used to check potential non-linear associations and to obtain ORs and 95% CIs of variables under study. Addictive interaction was estimated using relative excess risk due to interaction, attributable proportion due to interaction and synergy index. Area under the receiver operating characteristic curve was used to check increased predictive values.ResultsOf 1032 patients, 162 suffered from DR. Copresence of low phenylalanine and low tyrosine increased DR risk (OR 6.01, 95% CI 1.35 to 26.8), while either of them alone did not have a significant effect with significant additive interaction. Presence of diabetic nephropathy further increased the OR of copresence of low phenylalanine and low tyrosine for DR to 25.9 (95% CI 8.71 to 76.9) with a significant additive interaction. Inclusion of phenylalanine and tyrosine in a traditional risk factor model significantly increased area under the curve from 0.81 to 0.83 (95% CI 0.80 to 0.86).ConclusionPlasma low phenylalanine and low tyrosine worked independently and synergistically to increase the risk of DR in T2D. Presence of renal dysfunction further amplified the effect of copresence of low phenylalanine and low tyrosine on DR risk.
