The Impact

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.

The purpose of this study was to translate and culturally adapt the Carpal Tunnel Questionnaire to produce an equivalent Korean version. A total of 53 patients completed the Korean version of the Carpal Tunnel Questionnaire pre-operatively and 3 months after open carpal tunnel release. All 53 also completed the Korean version of the Disabilities of Arm, Shoulder, and Hand questionnaire pre-operatively and 3 months post-operatively. Reliability was measured by determining the test–retest reliability and internal consistency. Test–retest reliability was assessed using intraclass correlation coefficients and paired t-tests, and internal consistency using Cronbach’s alpha coefficients. Pearson correlation analysis was carried out on the Korean version of the Carpal Tunnel Questionnaire scores and the Korean version of the Disabilities of Arm, Shoulder, and Hand scores to assess construct validity. Responsiveness was evaluated using effect sizes and standardized response means. The reliability of the Korean version of the Carpal Tunnel Questionnaire was good. The scores in the Korean version of the Disabilities of Arm, Shoulder, and Hand strongly correlated with the scores in the Korean version of the Carpal Tunnel Questionnaire. Standardized response mean and effect size were both large for the Korean version of the Carpal Tunnel Questionnaire. The study shows that the Korean version of the Carpal Tunnel Questionnaire is a reliable, valid and responsive instrument for measuring outcomes in carpal tunnel syndrome.

The Autism-Tics, AD/HD, and other Comorbidities (A–TAC) inventory is used in epidemiological research to assess neurodevelopmental problems and coexisting conditions. Although the A–TAC has been applied in various populations, data on retest reliability are limited. The objective of the present study was to present additional reliability data. The A–TAC was administered by lay assessors and was completed on two occasions by parents of 400 individual twins, with an average interval of 70 days between test sessions. Intra- and inter-rater reliability were analysed with intraclass correlations and Cohen's κ. A–TAC showed excellent test-retest intraclass correlations for both autism spectrum disorder and attention deficit hyperactivity disorder (each at .84). Most modules in the A–TAC had intra- and inter-rater reliability intraclass correlation coefficients of ≥ .60. Cohen's κ indicated acceptable reliability. The current study provides statistical evidence that the A–TAC yields good test-retest reliability in a population-based cohort of children.

Diagnostic Thinking

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.

Limitations in hand function are common among children with cerebral palsy (CP), with almost 50% presenting an arm–hand dysfunction. However, there is no standardized assessment tool available in Italian for evaluating bimanual performance for this population. Our objective in this study was to evaluate the psychometric properties of an Italian translation of the ABILHAND-Kids (ABILHAND-Kids-IT) among children with CP. We examined internal consistency using Cronbach’s Alpha and Omega coefficients, and we investigated test-retest reliability with intraclass correlation coefficients (ICC). We performed explorative factor analysis (EFA) to investigate structural validity. We calculated Pearson’s correlation coefficients between the ABILAND-Kids IT and the Manual Ability Classification System (MACS) to assess criterion validity; and, to demonstrate the score variability of the ABILHAND-Kids-IT, we used analyses of variance (ANOVAs) to compare the 181 children with CP in this sample with their levels on the MACS. We enrolled 181 children with CP in the study. EFA confirmed a uni-dimensional scale. We obtained internal consistency on both Cronbach’s Alpha and Omega coefficient of 0.98, and a one-week test-retest reliability analysis revealed an ICC with 95% of confidence interval of .992. The ANOVA revealed significant score variability ( p < 0.01) and the Pearson correlation coefficient comparing the ABILHAND-Kids-It score with the MACS was –0.929 ( p < 0.01). We conclude that the ABILHAND-Kids-IT is valid and reliable for use with Italian children with CP.

ObjectiveTo evaluate health-related quality of life (HRQoL) in Cushing's syndrome (CS) with the disease-generated CushingQoL questionnaire and to confirm its psychometric properties of test–retest reliability and sensitivity to change.DesignClinical practice conditions in a tertiary referral center.MethodsThe CushingQoL and EuroQoL questionnaires were administered at baseline and during follow-up and correlated with clinical parameters in 59 patients with CS. To check test–retest reliability, stable patients (either biochemically cured or with active hypercortisolism) were evaluated twice. To investigate sensitivity to change, new patients were evaluated at diagnosis and twice more following improvement after successful surgery.ResultsAt baseline, patients with active disease scored lower (indicating worse HRQoL) than those cured on the CushingQoL (46±14 vs 58±20, P<0.05) but not on the EuroQoL-visual analog scale (VAS; 64±20 vs 70±16, P NS). Test–retest reliability of CushingQoL was confirmed in stable patients, both in the ‘cured group’ (intraclass correlation coefficient (ICC)=0.78, n=34) and in the ‘active group’ (ICC=0.66, n=14). Sensitivity to change was confirmed in the ‘improvement group’ (n=11), as the CushingQoL score increased 4±1.5 and 9±3 months after surgery (P<0.01 and <0.001 respectively); the EuroQoL-VAS only improved after 9±3 months (P<0.01). Effect sizes were 1.02 and 1.86 for CushingQoL at 4±1.5 and 9±3 months respectively. Finally, scores of both questionnaires were correlated (r=0.504; P<0.001).ConclusionsThe CushingQoL questionnaire shows good test–retest reliability and sensitivity to change in clinical practice conditions.

Abstract Background and Objectives Tools to measure self-perceived communication between persons with early-stage dementia and their caregivers are lacking. Therefore, we developed a questionnaire for Experienced Communication in Dementia (ECD) with a patient version (ECD-P) and a caregiver version (ECD-C), that contains items on (1) caregiver competence, (2) social communication, (3) communication difficulties, and (4) experienced emotions. This article describes the feasibility and clinimetric evaluation of this instrument. Research Design and Methods A prospective observational cohort study was conducted with 57 dyads (community-dwelling person with dementia and primary caregiver). ECD-P, ECD-C, and measures on quality of life, caregiver burden, cognitive functioning, physical functioning, and functional independence were administered. After two weeks, the dyads filled out the ECD again. Feasibility (completion time and missing values per item), internal consistency (Cronbach’s α), test-retest reliability (intraclass correlation coefficients (ICCs)) and construct validity (hypotheses testing with Spearman’s r) were evaluated. Results Mean completion time was ten minutes per questionnaire. ICCs for test-retest reliability ranged from 0.67 to 0.78, except for ECD-P2 (ICC = 0.31). Internal consistency ranged from α = 0.75 to 0.82 for ECD-P1 and all parts of ECD-C, except for ECD-P2 (α = 0.66). Correlation coefficients for convergent validity ranged from r = 0.31 to 0.69 and correlation coefficients for divergent validity were r &lt; 0.20 and statistically insignificant. Discussion and Implications Pending future research, the ECD, except part ECD-P2, seems to be a promising tool to measure experienced communication between persons with early-stage dementia and their caregivers.

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.

The Impact

Background: Third-party hearing loss-related quality of life (HLQoL) reports measure the third-party disability as a result of communicating regularly with someone with hearing loss. Scales with known psychometric characteristics validated on a diverse subject population are needed in order to describe the activity limitations and participation restrictions experienced by spouses as a result of living with an individual with hearing loss. Purpose: The purpose of the present study was to develop a scale to measure third-party HLQoL in spouses of people with hearing loss with acceptable psychometric characteristics. This scale is known as the Hearing Impairment Impact–Significant Other Profile (HII-SOP). Research Design: In Study 1, the initial test items were developed and evaluated with a factor analysis for adequate construct validity. In Study 2, the internal consistency reliability, the validity, and the test-retest reliability of the revised test were evaluated. Study Sample: In Study 1, 120 people between 34 and 87 yr of age participated and in Study 2, 164 people between 23 and 88 yr of age participated. Data Collection and Analysis: In Study 1, a 41-item questionnaire was developed based on five content areas: physical adjustment, social activities, emotional reaction, intimate relationship, and change in roles. The scale was submitted to a factor analysis to analyze interrelationships among items, determine the underlying dimensions, and select items for the final scale. In Study 2, the internal consistency reliability, construct validity, and test-retest reliability were evaluated in the revised 20-item questionnaire. The internal-consistency reliability was measured using Cronbach's alpha. Validity was assessed by observing the correlations of the new scale with well-established scales measuring related constructs: overall health-related quality of life, marital communication, HLQoL, and negative affect, in both the person with hearing loss and the spouse. Test-retest reliability was measured in a subset of the spouses who completed the HII-SOP between 2 and 4 wk after the initial scale was completed. Results: The HII-SOP is a 20-item scale with three subscales which measure: (1) the emotions that arise when having a spouse with hearing loss as well as the impact of the hearing loss on the marital relationship, (2) the impact of the hearing loss on the social life of the spouse, and (3) the communication strategies used by the spouse. The scale and its subscales have adequate internal-consistency reliability suggesting that the 20 items do measure a single construct and the subscales do measure distinct subconstructs. The HII-SOP scale was significantly correlated with measures expected to relate to the construct of third-party disability associated with hearing loss. Finally, the HII-SOP scale has adequate test-retest reliability (r = 0.90) and the 95% critical differences is 19.7 points. Conclusions: The HII-SOP is a scale to measure third-party HLQoL in spouses of individuals with hearing loss. Scores of 20–39 reflect mild third-party disability, scores of 40–59 reflect moderate third-party disability, and scores >60 reflect severe third-party disability associated with hearing loss.
