The Tinnitus Handicap Inventory (THI; C. W. Newman, G. P. Jacobson, & J. B. Spitzer, 1996) is widely used in a clinical context to assess tinnitus-related self-reported handicap and to report treatment outcomes. Test-retest reliability has been reported to be high, and high convergent validity with other measures of tinnitus distress has been reported. Factor analysis of the subscales of the THI has previously been reported for a Danish translation, but not for the English version. In the present study, the THI was factor analyzed using data collected from a group of 80 clinical tinnitus patients and 116 patients with unilateral vestibular schwannoma. The factor analysis yielded strong support for a unifactorial structure of the scale, with a majority of items loading on the first factor, and high internal consistency of the total score. The authors recommend use of the total score in research and in clinical practice.

Introduction Several general hand functional assessment tools for Dupuytren’s disease have been reported, but none of the patient-reported-outcome measures specific to Dupuytren’s disease-associated disabilities are available in the Italian language. The purpose of this study was to culturally adapt the Unité Rhumatologique des Affections de la Main (URAM) into Italian (URAM-I) and determine its measurement properties. Methods Cross-cultural adaptation was performed according to the current guidelines. Construct validity (convergent and divergent validity) was measured by comparing the URAM-I with the Pain-Rated Wrist/Hand Evaluation (PRWHE-I), Short-Form 36 (SF-36-I) scale and finger range of motion, respectively. Factor analysis was used to investigate the URAM-I’s internal structure. Reliability was assessed by internal consistency (Cronbach’s alpha) and test-retest reliability by Intra-Class Correlation Coefficient (ICC). Results This study included 96 patients (males = 85%, age = 66.8 ± 9.3). Due to the cultural adaptation, we divided the original item #1 into two separate items, thus generating the URAM-I(10). Convergent validity analysis showed a strong positive (r = 0.67), significant (p < 0.01) Pearson’s correlation with the PRWHE-I. Divergent validity analysis showed a weak, negative (r < 0.3) and not significant correlation with the SF-36-I subscales, except for the physical pain subscale (r = −0.21, p < 0.05). Factor analysis revealed a 2-factor, 4-item solution that explained 76% of the total variance. The URAM-I(10) demonstrated high internal consistency (α = 0.94) and high test-retest reliability (ICC = 0.97). Conclusion The URAM-I(10) demonstrates moderate construct validity, high internal consistency and test-retest reliability, and showed a 2-factor internal structure. Its evaluative use can be suggested for the Italian Dupuytren’s population.

This study evaluated the psychometric properties of a Chinese version of the 24-item Social Environment Questionnaire (SEQ-C). Confirmatory factor analysis was used to examine the factor validity and measurement invariance (Purpose 1) of the SEQ-C in 453 older adults in Hong Kong. Convergent validity (Purpose 2) and test–retest reliability (Purpose 3) were also measured. The results of the confirmatory factor analysis and measurement invariance supported the four-factor structure (representing companionship, encouragement, neighborhood social cohesion, and role models) of the SEQ-C, in a 15-item model that closely fitted the data. The SEQ-C was also found to have acceptable to satisfactory internal consistency, test–retest reliability, composite reliability, and moderate convergent validity in correlating perceived social support. This study showed that the SEQ-C is a suitable means of measuring the social environments of older adults in Hong Kong.

The English version of Hand20 questionnaire was translated into Greek and cultural adaptation was performed. The validity was assessed in 134 patients with a variety of upper limb disorders. A comparison of Hand20 and DASH was also performed. All patients completed EQ-5D, Hand20 and DASH questionnaire. Test–retest reliability was assessed in a subgroup of 37 patients. We assessed the convergent validity of Hand20 by correlating its scores to DASH and EQ-5D scores. We also compared the completeness of Hand20 and DASH. We found no statistically significant differences in Hand20 scores between the 1st and 2nd measurements as well as a strong correlation between Hand20 and the other two questionnaires. There were also better rates of response and fewer missing data even in elderly individuals.

The psychometric properties of a Greek translation of the 10-item Body Appreciation Scale-2 (BAS-2) was examined. A total of 193 Greek-speaking female university students from Cyprus completed the BAS-2, along with measures of appearance satisfaction, investment in appearance, weight-related anxiety, self-esteem and body image quality of life. Principal-axis factor analysis indicated that the Greek version of the BAS-2 scores had a one-dimensional factor structure. A Confirmatory Factor Analysis confirmed the unidimesionality of the measure. Further analyses indicated that Greek BAS-2 scores evidenced internal consistency, test-retest reliability and convergent validity with the other variables of interest. These results suggest that the Greek version of the BAS-2 has adequate psychometric properties and can be used within the Greek-speaking populations.

Obsessive Compulsive Drinking Scale (OCDS) was established and introduced to measure the craving for alcohol and the severity of alcohol dependence. However, the Chinese version of OCDS is still unavailable and has not been validated in the Chinese population. We tended to translate and validate the OCDS in Chinese. We translated original OCDS into Chinese through bi-direction translations and tested the reliability and validity. We found that Chinese OCDS had high internal consistency and good test-retest reliability. The Chinese OCDS also presented good internal structure to reflect the severity of alcohol dependence. The Chinese OCDS could be used in clinical studies and research among the Chinese population.

Background Occupational balance, a fundamental concept in occupational therapy, is the arrangement of right amount and variety of occupations contributes to a person’s health and well-being. This study was aimed to investigate the reliability and validity of the Chinese version of the Occupational Balance Questionnaire (OB-Quest) for people with insomnia. Methods The OB-Quest was translated into traditional Chinese and reviewed by an expert panel for content validity, cultural relevance and translation accuracy. Internal consistency, factor analysis and convergent validity, as well as test–retest reliability, were explored. Results The participants (n = 205), 115 adults with insomnia and 90 adults without insomnia, completed a survey of demographic background, the Chinese version of OB-Quest and the Chinese Insomnia Severity Index (C-ISI). The Chinese version of OB-Quest demonstrated excellent test–retest reliability (ICC= 0.98) and good internal consistency (Cronbach’s α  =  0.80). Factor analysis indicated that a single-factor solution explained 42% of the variance, and 9 out of 10 items had a factor loading of 0.4 or above. The Chinese version of OB-Quest had significant correlations with C-ISI (r = –0.88; p < 0.001). A significant difference was found in occupational balance between groups with different levels of insomnia severity and without insomnia (F = 169.72; p < 0.001). As in a previous study, age, living environment and life role had no significant relationship with occupational balance. Conclusion The Chinese version of OB-Quest is a short, easy to understand and culturally relevant assessment for Chinese. It demonstrates satisfactory psychometric properties and had significant correlations with insomnia.

ABSTRACTBackground: This paper reports the development and validation of the Chinese Significant Wish Fulfillment Scale (CSWFS), a new multidimensional scale for assessing the perceived importance and level of fulfillment of wishes of older adults.Methods: Three studies were involved. Study 1 developed a 26-item pool on wish fulfillment through in-depth interviews with 22 older adults. Study 2 reduced the pool to 23 items through validation with a new sample of 315 older adults and examined the internal reliability. Study 3 involved a confirmatory factor analysis (CFA) and examined the test-retest reliability and the convergent validity of the scale with the construct of regret.Results: A five-factor structure model of 23 items was identified through exploratory factor analysis, which accounted for 51.67% of variance. As informed by the CFA in Study 3, a five-factor 22-item model was the best fit. Internal reliability and test-retest reliability was found to be good. Convergent validity was examined through correlation with the construct of future regret. The correlation, though statistically significant, was small.Conclusion: CSWFS demonstrates good psychometric properties, but the construct might be slightly different from that of future regrets. Probably, CSWFS addresses a construct that is under-explored but is of importance to older adults and especially to the Chinese community.

Measuring parental self-efficacy has influenced the children and their environment for reaching optimal development. The current study aimed to adapt the Tool to Measure Parenting Self-Efficacy (TOPSE) scale and to determine its psychometric properties for using in the context of Bangladesh. A total of 180 mothers of children aged 0 to 6 years were conveniently selected for this study. The TOPSE and Rosenberg’s Self-Esteem scale were used as measuring instruments. Collected data were analyzed to determine psychometric properties by using Cronbach’s alpha, Pearson product moment correlation coefficient, item analysis, and factor analysis. TOPSE had acceptable internal consistency (Coefficient alpha=0.89) and test-retest reliability (r=0.96). The convergent validity of TOPSE showed a highly positive correlation (r=0.91) with the Bangla Rosenberg’s Self-Esteem scale. The factor analysis resulted in 4 factors with Eigenvalues > 1, explaining 87% of the variances and the four factors showed Cronbach’s coefficient values ranging from 0.50 to 0.99. TOPSE has reasonably good psychometric properties. Further research may wish to require to see the implication of TOPSE in evaluating parenting programs in Bangladesh. Dhaka Univ. J. Biol.

Background: Only 61% of Malawian women exclusively breastfeed to the recommended 6 months. Paternal support is predictive of exclusive breastfeeding, and significantly related to paternal breastfeeding self-efficacy, defined as fathers’ confidence in their ability to assist mothers with breastfeeding. Research Aims: To (1) examine the psychometric properties of the Paternal Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) in Malawian fathers, including internal consistency reliability, test-retest reliability, construct validity using Confirmatory Factor Analysis (CFA), and convergent validity; and (2) assess the relationship between the BSES-SF and paternal demographic and health factors. Methods: A cross-sectional study was conducted at a maternity hospital in Lilongwe, Malawi, and 180 fathers whose partners had delivered a singleton infant were included. Participants completed the Breastfeeding Self-Efficacy Scale and Quality of Life with confirmatory factor analysis performed to assess the construct validity. The internal consistency reliability and test-retest reliability were evaluated using Cronbach’s alpha coefficient and intra-class correlations. Convergent validity was also assessed. Results: A unidimensional factorial structure of the Malawian Paternal BSES-SF was identified using confirmatory factor analysis. The scale had an excellent Cronbach’s alpha of .90 and a test-retest reliability of .93. Participants’ breastfeeding self-efficacy was significantly correlated with the Quality of Life domains of psychological health ( r = .23; p < .01), social relationships ( r = .28; p < .001), and environmental health ( r = .30; p < .001). Participants who were older, married, and with ≥ two children had significantly higher breastfeeding self-efficacy and were more confident in their ability to support their partner’s breastfeeding. Conclusion: The Paternal Breastfeeding Self-Efficacy Scale-Short Form was a valid and reliable measure to assess fathers’ confidence in their ability to assist mothers with breastfeeding in Malawi.

Background Adequate muscle strength, power, and endurance are important in children's daily activities and sports. Various instruments have been developed for the assessment of muscle function; each measures different aspects. The Functional Strength Measurement (FSM) was developed to measure performance in activities in which strength is required. Objective The study objective was to establish the test-retest reliability and structural and construct validity of the FSM. Design A cross-sectional descriptive study was conducted. Methods The performance of 474 children with typical development on the FSM was examined. Test-retest reliability (n=47) was calculated with the intraclass correlation coefficient (2.1A) for agreement. Structural validity was examined with exploratory factor analysis, and internal consistency was established with the Cronbach alpha. Construct validity was determined by calculating correlations between FSM scores and scores obtained with a handheld dynamometer (HHD) (n=252) (convergent validity) and between FSM scores and scores on the Movement Assessment Battery for Children–2 (MABC-2) (n=77) (discriminant validity). Results The test-retest reliability of the FSM total score ranged from .91 to .94. The structural validity revealed one dimension, containing all 8 FSM items. The Cronbach alpha was .74. The convergent validity with the HHD ranged from .42 to .74. The discriminant validity with MABC-2 items revealed correlations that were generally lower than .39, and most of the correlations were not significant. Exploratory factor analysis of a combined data set (FSM, HHD, and MABC-2; n=77) revealed 2 factors: muscle strength/power and muscle endurance with an agility component. Limitations Discriminant validity was measured only in children aged 4 to 6 years. Conclusions The FSM, a norm-referenced test for measuring functional strength in children aged 4 to 10 years, has good test-retest reliability and good construct validity.
