UNLABELLED The Hearing Handicap Inventory for Adults (HHIA) translated into Brazilian Portuguese has been used for clinical practice and research purposes; however, information regarding its ease of reading and psychometric properties are still lacking. AIM To evaluate the ease of reading and psychometric properties of the Brazilian translation of this tool, including its validity and reliabi...

The authors developed a computer-based medical history for patients to take in their homes via the internet. The history consists of 232 'primary' questions asked of all patients, together with more than 6000 questions, explanations, and suggestions that are available for presentation as determined by a patient's responses. The purpose of this research was to measure the test-retest reliability...

BACKGROUND Intensity peaks and valleys in the acoustic signal are salient cues to syllable structure, which is accepted to be a crucial early step in phonological processing. As such, the ability to detect low-rate (envelope) modulations in signal amplitude is essential to parse an incoming speech signal into smaller phonological units. PURPOSE The Parsing Syllable Envelopes (ParSE) test was ...

The error-related negativity (ERN) is a negative deflection in the event-related potential (ERP) following an erroneous response and is thought to reflect activity of the anterior cingulate cortex. There is accumulating evidence that the component has trait-like properties; prior evidence further suggests test-retest reliability estimates ranging from .40 to .82 over a period of 2 to 6 weeks. T...

BACKGROUND Items from respiratory questionnaires validated in older children are often used in research studies of preterm infants, although they have not been validated in this population. We aimed to assess both test-retest reliability and convergent validity of a group of commonly used respiratory questionnaire items in a cohort of preterm infants. METHODS The health status of 300 preterm ...

BACKGROUND The objective of this study was to test the data quality, test-retest reliability and hospital-level reliability of the Patient-Reported Incident in Hospital Instrument (PRIH-I). METHODS 13 incident questions were included in a national patient-experience survey in Norway during the spring of 2011. All questions and a composite incident index were assessed by calculating missing-it...

OBJECTIVE The purpose of this study is to establish the test-retest reliability of the Child-Initiated Pretend Play Assessment (ChIPPA) (Stagnitti, 2002a; Stagnitti, Unsworth, & Rodger, 2000). METHOD The first author rated 38 preschool children ages 4 and 5 years (4 with developmental delay and 34 typically developing) on the ChIPPA. The ChIPPA employs conventional play materials and unstruct...

OBJECTIVE To introduce and verify an algorithm designed to administer adaptive speech-in- noise testing to a specified reliability at selectable points on the psychometric function. DESIGN Speech-in-noise performances were measured using BKB sentences presented in diffuse babble-noise, using morphemic scoring. Target of the algorithm was a test-retest standard deviation of 1.13 dB within the ...

OBJECTIVE This research established test-retest reliability and construct validity for the Neck Pain and Disability Scale (NPAD). METHODS Two groups of patients with neck pain completed the NPAD. The first group filled out the scale twice before treatment, whereas the second completed it with a number of other outcome measures once a month for 4 months, for evaluation of treatment with inject...

The disability profile of persons with schizophrenia in Singapore and how disability levels vary in patients cared for in the community and in the long-stay wards of a state mental hospital were studied using the Life Skills Profile (LSP). The inter-rater reliability of the LSP assessed by the intraclass correlation coefficient (ICC), was lower than in the Australian studies. The test-retest IC...
