Pathological hoarding results in clutter that precludes normal activities and creates distress or dysfunction. It may lead to an inability to complete household functions, health problems, social withdrawal, and even death. The aim of this study was to describe the validation of the Brazilian version of the hoarding assessment instrument, the Saving Inventory–Revised. Sixty-five patients with obsessive-compulsive disorder (OCD) and 70 individuals from the community were assessed using the Structured Clinical Interview for the Diagnosis of DSM–IV (clinical sample), the Saving Inventory–Revised, the Obsessive-Compulsive Inventory–Revised, the Beck Depression Inventory, and the Beck Anxiety Inventory. The Brazilian version of the Saving Inventory–Revised exhibited high internal consistency (Cronbach's alpha = .94 for OCD and .84 for controls), high to moderate test-retest reliability and, using the hoarding dimension of the Obsessive-Compulsive Inventory–Revised as a reference point, high to moderate convergent validity. The Saving Inventory–Revised total scores also correlated significantly with comorbid anxiety and depressive symptoms.

Objective. This study was conducted for development and validation of the Sasang Digestive Function Inventory (SDFI) with type-specific digestive function-related symptoms for identification of Sasang type and pathological pattern.Methods and Materials. We selected questionnaire items for pathophysiological symptoms using internal consistency analysis and examined construct validity using 193 healthy participants. Test-retest reliability with a four-week interval as well as convergent validity was examined using the Nepean Dyspepsia Index-Korean (NDIK), Functional Dyspepsia-Related Quality of Life (FDQOL), Dutch Eating Behavior Questionnaire (DEBQ), and Body Mass Index (BMI).Results. The 21-item SDFI showed satisfactory internal consistency (Cronbach’s alpha = 0.743) and test-retest reliability (r=0.886,P<0.001). Three extracted subscales, SDFI-Digestion, SDFI-Appetite, and SDFI-Eating pattern, explained 56.02% of the total variance. The SDFI showed significant (P<0.001) correlation with total symptom score of NDIK, FDRQOL-Eating status, DEBQ-External Eating scale, and BMI. The SDFI score of the Tae-Eum (50.62±8.05) type was significantly (P<0.001) larger than that of the So-Eum (43.11±11.26) type.Conclusion. Current results demonstrated the reliability and validity of the SDFI and its subscales, which can be utilized as an objective instrument for diagnosis of Sasang types and assessment of the type-specific digestive function.

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.

Background: There has been an increased effort to understand the nature of obsessive-compulsive disorder (OCD) in non-Western cultures. In particular, growing research has examined OCD in China, but there are no comprehensive instruments that measure both OCD severity and heterogeneity for characterizing samples. Aims: A validated, comprehensive measure that could be used in China would provide researchers with a useful instrument for evaluating severity and heterogeneity of OCD in a non-Western culture, allowing researchers to better understand the universal and cultural components that play a role in the nature of OCD. Method: The current investigation presents data on the reliability and validity of a Mandarin translation of the Obsessive-Compulsive Inventory-Revised (CH-OCI) using both a student (n = 1950) and clinical sample (n = 50 patients with OCD; n = 50 patients with anxiety as a comparison group). Results: Results support the factor structure, convergent and discriminant validity, criterion-related validity, test-retest reliability, and internal consistency of the CH-OCI. Conclusions: Validation of the instrument permits researchers and clinicians to measure OCD presentation in Mandarin-speaking samples.

The NPI-Q (Neuropsychiatry Inventory-Questionnaire) was developed to facilitate the evaluation of neuropsychiatric symptoms. This study evaluated the internal consistency, the test-retest reliability of the Brazilian NPI-Q version and its convergent validity with the original NPI.MethodThe NPI-Q and the NPI were administered to 64 caregivers of dementia patients. Thirteen informants were asked to complete a second NPI-Q form.ResultsThe internal consistency of the Brazilian NPI-Q version was 0.67 for the severity scale and 0.81 for the distress scale. The test-retest reliability of the total NPI-Q severity and the distress scales were 0.97 and 0.92, respectively (p < 0.001). There were significant correlations between the total NPI-Q severity score and the NPI (r = 0.75) and between the total NPI-Q distress score and the total NPI standard distress (r = 0.74).ConclusionThe Brazilian NPI-Q version showed evidence of good psychometric properties and can be used in general clinical practice.

The psychometric properties of a new scale, the Obsessive Compulsive Inventory (OCI; Foa, Kozak, Salkovskis, Coles, & Amir, 1998), were examined in a nonclinical student sample. The study was a partial replication of the original validation study by Foa et al. Test-retest reliability, internal consistency, and convergent validity were examined using a sample of 126 undergraduate psychology students. Statistical analyses (Pearson's r and Cronbach's alpha) indicated adequate test-retest reliability for the full scales and subscales (coefficients ranging from 0.69 to 0.88) and high internal consistency (all coefficients exceeding 0.7). Convergent validity with the Maudsley Obsessional Compulsive Inventory (MOCI; Hodgson & Rachman, 1977) was adequate for the full scales and for the Washing and Checking subscales (coefficients ranging from 0.61 to 0.75). The OCI is a useful supplement to existing self-report measures of obsessive-compulsive symptomatology.

Background: Self-management can be considered a way of dealing with oneself and relates to actions undertaken to create order, discipline, and control. The concept is closely linked to concepts of self-efficacy and self-regulation but can be distinguished from these. The Self-Management Self-Test (SMST) is a 5-item assessment scale designed to measure self-management competence in individuals with or without a psychiatric disorder (as screened using PHQ). The aim of this study was to validate the SMST in terms of convergent validity, the ability to differentiate, criterion validity, internal consistency, and test-retest reliability. Methods: Eighty-seven adults hospitalized for treatment of major depression (clinical sample) and 595 individuals from the general population (population sample) filled out the SMST and 5 other stress-related psychometric instruments measuring similar constructs. All instruments were repeated 4 to 6 weeks later. Convergent validity, internal consistency, and test-retest reliability were tested based on data from the population sample. Convergent validity was determined by correlations with other stress-related psychometric instruments. Correlations in the range of r = –0.4 to –0.6 were expected. To test for criterion validity, the clinical sample was matched with a subsample from the population sample, consisting only of individuals without a psychiatric disorder as screened using PHQ (nonclinical subsample, n = 87). The ability to differentiate was based on receiver operating characteristic (ROC) curve analysis. Results: Correlations between the SMST and the other stress-related tests were significant and in the expected direction and predominantly within the expected range (Pearson r = –0.40 to –0.64). The correlation with the Multidimensional Fatigue Inventory–20, measuring fatigue, and with the dimensional scale for depression in the PHQ was higher than expected and referred to very similar items. Thus, convergent validity mainly lay within the expected range. Internal consistency was high (Cronbach α = 0.80), and test-retest reliability was fairly low ( r = 0.71). The SMST showed a significant difference, t(157) = 7.97, P < .001, between the clinical sample (M = 9.36, SD = 3.39) and the nonclinical subsample (M = 12.94, SD = 2.47) with a large effect size ( d = 1.3). The area under the ROC curve (AUC) was excellent (AUC = 0.81, SE = 0.034, P < .001), suggesting that the SMST can distinguish between the clinical and nonclinical samples. Conclusions: The SMST can be considered an effective self-rating test to assess self-management competence in individuals from the general population as well as in people with major depression. It may also be useful to detect treatment outcomes in people with major depression. The high internal consistency indicates that all 5 items are important for the test as a whole. The low test-retest reliability suggests sensitivity to change. The SMST is likely to differentiate particularly well at low levels of self-management competence, suggesting it may be a useful tool in studies investigating people with depression or other psychiatric disorders such as post-traumatic stress disorder. Furthermore, the SMST could be useful in assessing the effect of treatment interventions over time and evaluating patient-reported outcomes.

Background Measuring implicit attitudes is difficult due to social desirability (SD). A new method, the Emotion Based Approach (EBA), can solve this by using emotions from a display of faces as response categories. We applied this on an EBA Spirituality tool (EBA-SPT) and an Actual Situation tool (EBA-AST). Our aim was to assess the structure, reliability and validity of the tools and to compare two EBA assessment approaches, i.e., an explicit one (only assessing final replies to items) and an implicit one (assessing also the selection process). Methods We obtained data on a sample of Czech adults (n = 522, age 30.3±12.58; 27.0% men) via an online survey; cortisol was assessed in 46 participants. We assessed the structure and psychometric properties (internal consistency and test-retest reliability; convergent, discriminant, and criterion validity) of the EBA, and examined the differences between explicit vs. implicit EBA approaches. Results We found an acceptable-good internal consistency reliability of the EBA tools, acceptable discriminant validity between them and low (neutral expression) to good (joy) test-retest reliability for concrete emotions assessed by the tools. An implicit EBA approach showed stronger correlations between emotions and weaker convergent validity, but higher criterion validity, than an explicit approach and standard questionnaires. Conclusion Compared to standard questionnaires, EBA is a more reliable approach for measuring attitudes, with an implicit approach that reflects the selection process yielding the best results.

Abstract Background Hemodialysis is considered a major therapeutic method for patients with chronic kidney disease. Pruritus is a common complaint of hemodialysis patients. The 5-D pruritus scale is amongst the most common tools to evaluate several dimensions of itch. Psychometric properties of the 5-D scale have not been evaluated in Persian speaking population with hemodialysis; hence, the objective of this study was to assess reliability and validity of the Persian version of the scale. Methods Ninety hemodialysis patients (men: 50, women: 40, mean age: 54.4 years) participated in this cross-sectional study. The final Persian version of 5-D scale was given to the participants. Tests Compared: One-third of the participants completed the scale twice within 3–7 days apart to evaluate test- retest reliability. Other psychometric properties including internal consistency, absolute reliability, convergent, discriminative and construct validity, floor/ceiling effects were also evaluated. Results The Persian 5-D scale has strong test-retest reliability (ICC= 0.98) and internal consistency (Cronbach’s alpha= 0.99). Standard error of measurement and minimal detectable change were 0.33 and 0.91, respectively. Regarding convergent validity, the scale had moderate correlation with numeric rating scale (r =0.67) and quality of life questionnaire related to itch (r = 0.59). Exploratory factor analysis revealed two factors within the scale. No floor or ceiling effect was found for the scale. Conclusion The Persian version of 5-D the itching scale is a brief instrument with acceptable reliability and validity. Therefore, the scale could be used by experts, nurses, and other health service providers to evaluate pruritus among Persian speaking hemodialysis patients.

Abstract Background This study was focused on translation and cultural adaptation of the English Lequesne Algofunctional index (LAI) into Bengali for patients with primary knee osteoarthritis (OA) and testing reliability and validity of the Bengali version of the LAI. Methods This study was carried out in the Department of Rheumatology, BSM Medical University, Dhaka, Bangladesh. Using the forward–backward method the English LAI was translated into Bengali including cultural adaptation. For pretesting, A sample of 40 patients with primary knee osteoarthritis were screened using the Bengali version of LAI. Following the pretest, 130 consecutive patients with symptomatic knee OA completed the interviewer administered Bengali LAI, the validated Bengali version of SF-36, Visual Analogue Scale for Pain, Distance Walked and Activities of Daily Living. For the retest 60 randomly selected patients from the cohort were administered the Bengali LAI 7 days later. An item by item analysis was performed. Internal consistency was assessed by Cronbach’s alpha, test–retest reliability by intraclass correlation coefficient (ICC) and Kappa coefficient, construct validity was measured using the Spearman rank correlation coefficient. Results It took 3.25 ± 0.71 min to complete the Bengali LAI and the mean score was 9.23 ± 4.58. For the Bengali LAI Cronbach’s alpha score was 0.88, test–retest reliability assessed by ICC was 0.97. For construct validity, excellent convergent validity was achieved (ρ = 0.93) but the divergent validity was moderate (ρ = 0.43). Conclusions The Bengali LAI showed excellent convergent validity, internal consistency and test–retest reliability, only the divergent validity was moderate. So, the Bengali LAI can be applied as a HRQoL assessment tool for primary knee OA patients.
