Abstract Diagnostic ability is essential for expert professional practice. Several instruments have been developed to assess diagnostic skills independent of specific knowledge. One such instrument is the diagnostic thinking inventory (DTI), which is used in different settings to evaluate diagnostic performance and has shown acceptable reliability and validity. The aim of the present study was to translate and validate a German version (DTI-G). Cultural adaptation and translation were performed according to international guidelines. Internal consistency and item discrimination indexes were calculated. The factorial structure of the DTI-G, test-retest reliability and known-groups validity were tested. A total of 388 physiotherapists completed the questionnaire. The internal consistency was good for the overall score of the DTI-G (Cronbach’s a = 0.84). Exploratory factor analysis yielded a five-factor solution with 21 items that explained 55% of the total variance across items. A confirmatory principal component analysis resulted in the same five-factor structure, showing an acceptable to good overall fit of the model (CFI = 0.93; RMSEA = 0.05; SRMR = 0.06). Test-retest reliability was found to be good (intraclass correlation coefficient ICC2,1 = 0.87, p < 0.001, n = 118). The difference between participants with more than 9 years of clinical experience and those with less than 9 years of clinical experience (median split) was significant (t385 = 6.00, p < 0.001), supporting known-groups validity. The results support construct validity and indicate good test-retest reliability of the DTI-G. The DTI-G can be used to measure and develop diagnostic ability of physiotherapists in clinical practice and education. Further research is necessary to validate the questionnaire for other health professions.

Purpose The Voice Handicap Index (VHI) questionnaire assesses the impact of total laryngectomy on voice-related quality of life. This study evaluates the Mandarin VHI, including its internal consistency, test–retest reliability, content validity, and differences in scores for Mandarin alaryngeal patients with pneumatic artificial laryngeal (PA) and esophageal (ES) speech. Method Translation and validation of the VHI questionnaire was performed through the forward–backward translation technique. This study used a sample of 78 PA and 23 ES participants from Taiwan who completed the Mandarin VHI. Forty-two of the alaryngeal participants completed the Mandarin VHI twice over a period of 7–63 days. Results The measurement of the internal consistency of the Mandarin VHI showed a high Cronbach's alpha coefficient for the total score (.975) and the functional (.930), physical (.939), and emotional (.938) subscales. Based on the results of the intraclass correlation coefficients, good test–retest reliability for the total and domain scores was found (intraclass correlation coefficient = .827–.863). Conclusion The Mandarin VHI was validated as an instrument with proper internal consistency and reliability, which supports the Mandarin VHI as a valid instrument for the self-evaluation of handicaps related to voice problems in PA and ES speakers.

Objectives. To culturally adapt and translate the Disabilities of Arm, Shoulder, and Hand questionnaire into Hindi (DASH-H) and assess its reliability, validity, and responsiveness in adult patients with shoulder tendonitis.Study Design. Descriptive methodological research, using longitudinal design.Setting. Outpatient clinic.Participants. 30 adult patients aged 53.3 ± 6.9 y with shoulder tendonitis.Data Analyses. DASH-H, visual analogue scales for pain (VAS-P) and disability (VAS-D), and shoulder active range of motion (AROM) were assessed at baseline, 2-3 days later, and 4-5 weeks after baseline. Intraclass correlation coefficients (ICC) assessed test-retest reliability of these scales and responsiveness was examined by calculating effect sizes (ES) and standardized response means (SRM). Cronbach’s alpha (CA) was used to examine internal consistency of DASH-H. Convergent construct validity of DASH-H with VAS scales and shoulder AROM was determined using Pearson’s Correlation Coefficients (r).Results. DASH-H demonstrated good test-retest reliability and internal consistency (ICC and CA both > 0.75) and excellent responsiveness (ES = 2.2, SRM = 6.1). DASH-H showed high concordance (r=-0.71,p<0.01) with AROM-flexion and moderate concordance (r>-0.4,p<0.05) with VAS scales and AROM-external rotation.Conclusion. Analyses indicate that DASH-H demonstrates good test-retest reliability, validity, and responsiveness in patients with shoulder tendonitis.

Background: Self-efficacy refers to the beliefs (i.e., confidence) individuals have in their capabilities to perform skills needed to accomplish a specific goal or behavior. Research in the treatment of various health conditions such as chronic pain, balance disorders, and diabetes shows that self-efficacy beliefs play an important role in treatment outcomes and management of the condition. This article focuses on the application of self-efficacy to the management of tinnitus. The first step in formally incorporating self-efficacy in existing treatment regimens or developing a self-efficacy approach for tinnitus treatment is to have a valid and reliable measure available to assess the level of tinnitus self-efficacy. Purpose: The objective of this study was to develop the Self-Efficacy for Tinnitus Management Questionnaire (SETMQ) and to obtain the psychometric properties of the questionnaire in a group of patients with tinnitus. Research Design: Observational study. Study Sample: A total of 199 patients who were enrolled in the Tinnitus Clinic at the James H. Quillen Veterans Affairs Medical Center participated in the current study. Data Collection and Analysis: The SETMQ was mailed to patients enrolled in the Tinnitus Clinic. The participants who completed one copy of the SETMQ were mailed a second copy to complete approximately 2 weeks later. An exploratory factor analysis was conducted to identify the most coherent subscale structure of the SETMQ. The internal consistency and test–retest reliability for each of the subscales and the questionnaire as a whole were assessed. The validity of the SETMQ also was evaluated by investigating the relations between the SETMQ and other clinical measures related to tinnitus. Results: Five components emerged from the factor analysis that explained 75.8% of the variance related to the following areas: (1) routine tinnitus management, (2) emotional response to tinnitus, (3) internal thoughts and interaction with others, (4) tinnitus concepts, and (5) use of assistive devices. Four items failed to load on any factor and were discarded, resulting in 40 items on the final SETMQ. The internal consistency reliability of the overall questionnaire and for each subscale was good (Chronbach's α ranged from .74 to .98). Item-total correlations ranged from .47 to .86, indicating that each item on the SETMQ correlated at a moderate or marked level with the SETMQ aggregate score. Intraclass correlation coefficients were computed to determine the test–retest reliability of the SETMQ total scale and separately for each subscale, which were all above .80, indicating good test–retest reliability. Correlations among the SETMQ subscales and various tinnitus-related measures (e.g., Tinnitus Handicap Inventory, tinnitus loudness rating, tinnitus distress rating, etc.) were significant, albeit indicative of fair to good relations overall (range r = –.18 to –.53). Conclusions: The results of the current study suggest that the SETMQ is a valid and reliable measure that may be an insightful instrument for clinicians and investigators who are interested in assessing tinnitus self-efficacy. Incorporating self-efficacy principles into tinnitus management would provide clinicians with another formalized treatment option. A self-efficacy approach to treating tinnitus may result in better outcomes compared with approaches not focusing on self-efficacy principles.

IntroductionUnderstanding the psychometric properties of health related quality of life (HRQoL) questionnaires can help inform selection in clinical trials.ObjectiveTo assess the psychometric properties of HRQoL questionnaires in bronchiectasis.MethodsA literature search was conducted. HRQoL questionnaires were assessed for psychometric properties (reliability, validity, minimal clinically important difference (MCID), floor/ceiling effects). Meta-analyses assessed the associations of HRQoL with clinical measures and responsiveness of HRQoL in clinical trials.Results166 studies and 12 HRQoL questionnaires were included. The BHQ, LCQ, CAT and SF-36 had good internal consistency in all domains reported (Cronbach's α≥0.7) across all studies and the QoL-B, SGRQ, CRDQ and SOLQ had good internal consistency in all domains in the majority of (but not all) studies. The BHQ, SGRQ, LCQ and CAT had good test-retest reliability in all domains reported ((intraclass correlation coefficient) ICC ≥0.7) across all studies and the QoL-B, CRDQ and SOLQ had good test-retest reliability in all domains in the majority of (but not all) studies. HRQoL questionnaires were able to discriminate between demographics, important markers of clinical status, disease severity, exacerbations and bacteriology. For HRQoL responsiveness, there was a difference between the treatment and placebo effect.ConclusionSGRQ was the most widely used HRQoL questionnaire in bronchiectasis studies and it had good psychometric properties, however good psychometric data are growing on bronchiectasis specific HRQoL questionnaires, QoL-B and BHQ. Future studies should focus on the medium-long term test-retest reliability, responsiveness and MCID in these HRQoL questionnaires which show potential in bronchiectasis.

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.

Purpose Relational dynamics between patients and staff in forensic settings can be complicated and demanding for both sides. Reflective practice groups (RPGs) bring clinicians together to reflect on these dynamics. To date, evaluation of RPGs has lacked quantitative focus and a suitable quantitative tool. Therefore, a self-report tool was designed. This paper aims to pilot The Relational Aspects of CarE (TRACE) scale with clinicians in a high-secure hospital and investigate its psychometric properties. Design/methodology/approach A multi-professional sample of 80 clinicians were recruited, completing TRACE and attitudes to personality disorder questionnaire (APDQ). Exploratory factor analysis (EFA) determined factor structure and internal consistency of TRACE. A subset was selected to measure test–retest reliability. TRACE was cross-validated against the APDQ. Findings EFA found five factors underlying the 20 TRACE items: “awareness of common responses,” “discussing and normalising feelings;” “utilising feelings,” “wish to care” and “awareness of complicated affects.” This factor structure is complex, but items clustered logically to key areas originally used to generate items. Internal consistency (α = 0.66, 95% confidence interval (CI) = 0.55–0.76) demonstrated borderline acceptability. TRACE demonstrated good test–retest reliability (intra-class correlation = 0.94, 95% CI = 0.78–0.98) and face validity. TRACE indicated a slight negative correlation with APDQ. A larger data set is needed to substantiate these preliminary findings. Practical implications Early indications suggested TRACE was valid and reliable, suitable to measure the effectiveness of reflective practice. Originality/value The TRACE was a distinctive measure that filled a methodological gap in the literature.

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.

Background: The Sexual Interest and Desire Inventory Female (SIDI-F) is a clinician-administered scale that allows for a comprehensive assessment of symptoms related to Hypoactive Sexual Desire Dysfunction (HSDD). As self-report questionnaires may facilitate less socially desirable responding and as time and resources are scarce in many clinical and research settings, a self-report version was developed (SIDI-F-SR). Aim: To investigate the agreement between the SIDI-F and a self-report version (SIDI-F-SR) and assess psychometric properties of the SIDI-F-SR. Methods: A total of 170 women (Mage=36.61, SD=10.61, range=20-69) with HSDD provided data on the SIDI-F, administered by a clinical psychologist via telephone, and the SIDI-F-SR, delivered as an Internet-based questionnaire. A subset of 19 women answered the SIDI-F-SR twice over a period of 14 weeks. Outcomes: Intraclass correlation as well as predictors of absolute agreement between SIDI-F and SIDI-F-SR, as well as internal consistency, test-retest reliability, and criterion-related validity of the SIDI-F-SR were examined. Results: There was high agreement between SIDI-F and SIDI-F-SR (ICC=.86). On average, women scored about one point higher in the self-report vs. the clinician-administered scale. Agreement was higher in young women and those with severe symptoms. Internal consistency of the SIDI-F-SR was acceptable (α=.76) and comparable to the SIDI-F (α=.74). When corrections for the restriction of range were applied, internal consistency of the SIDI-F-SR increased to .91. Test-retest-reliability was good (r=.74). Criterion-related validity was low but comparable between SIDI-F and SIDI-F-SR.

The Infant Temperament Questionnaire, originally published in 1970, has been revised to improve its psychometric characteristics. The number of items was increased from 70 to 95, rating options were increased from three to six, more items have high-low reversals, and they are randomized as to content area. The new form was standardized on 203 4- to 8-month-old infants. Good test-retest reliability was maintained and internal consistency of the nine categories was raised to a higher level, thereby assuring a greater reliability of the instrument. These improvements should enhance the questionnaire's use in clinical and research applications.

Linguistic, reliable, and valid secondary efficacy measures are important in clinical settings and studies. The aim of the study is to report test–retest reliability and construct validity of Turkish version of Myasthenia Gravis-Activities of Daily Living Scale (MG-ADL-T) in Myasthenia Gravis (MG) patients. Fifty-two ocular and generalized individuals with MG, applying to rehabilitation center, were included in the study. MG-ADL-T, MG quality-of-life questionnaire (MG-QoL), MG composite (MGC), quantitative MG score (QMGS), and pulmonary function test were administered. Reliability was assessed with intraclass correlation coefficient (ICC) and Cronbach’s alpha. Spearman correlation test and receiver operating characteristic (ROC) analysis were performed for construct validity. MG-ADL-T had fair internal consistency (Cronbach’s α = .67), excellent test–retest reliability (ICC = 0.96) and moderate construct validity (MG-QoL, r = 0.59; QMGS, r = .58; MGC, r = .68). MG-ADL, a unique scale that evaluates activities of daily living (ADL), has good test–retest reliability and construct validity in Turkish MG patients.
