Not gendered… but different from each other? A structural equation model for explaining risky road behaviors of female and male pedestrians.
2020
Abstract As alternative transportation is getting more and more fashionable, and more people worldwide are "shifting" to walking trips, even for their daily commuting, traffic crashes suffered by pedestrians are still a great concern for road safety and public health researchers and practitioners. In this regard, risky or "aberrant" road behaviors have emerged, during the last few years, as a key issue to be considered for crash prevention. Nevertheless, the idea of a "generic pedestrian" is getting re-evaluated, and analyzing key features, such as gender, seems to be crucial for understanding pedestrians' performance and safety outcomes. Objective The objective of this study was to examine…
Validation of the psychosocial impact of dental aesthetics questionnaire (Pidaq) in Spanish adolescents
2012
Objectives: The purpose of this study was to assess the validity and reliability of the Spanish version of PIDAQ for application in adolescents. Study Design: The questionnaire was translated, cross-culturally adapted and completed by 627 adolescents (366 12-year-olds and 261 15-year-olds). The adolescents were also examined by 4 examiners who had been calibrated against a gold standard and relative to each other (Kappa >0.85) in determining treatment need with the Dental Aesthetic Index (DAI) and the Index of Orthodontic Treatment Need (IOTN) DHC and AC components. Results: Cronbach´s alpha of the translated PIDAQ was 0.90. The 23 items of the questionnaire were divided into four domains t…
Repeated assessment of the Tower of Hanoi test: reliability and age effects.
2000
The purpose of this research was to analyze the effects of repeating an executive function test. Three versions of the Tower of Hanoi (TOH) test were repeated three times each, with test-retest intervals of 2 months. Two groups of children participated in the research (7.7 and 11.6 years, n = 22 and n = 28). Repeating the assessment improved the performance and decreased the total performance time in both of the groups. The older participants improved their performance faster than the younger ones. The reliability of all the scores, besides the error scores, seemed to be satisfactory after the first few assessments. The stability of the scores was maintained through all the assessments. Th…
Reliability and concurrent validity of spatiotemporal stride characteristics measured with an ankle-worn sensor among older individuals
2019
Background. Wearable inertial sensors have been shown to provide valid mean gait characteristics assessments, however, assessment of variability is less convincingly established. Research question. What level of concurrent validity, and session-to-session reliability does an ankle-worn inertial measurement unit (IMU)-based gait assessment with a novel angular velocity-based gait event detection algorithm have among older adults? Methods. Twenty seven (women N = 17) participants volunteered (age 74.4 (SD 4.3) years, body mass 74.5 (12.0) kg, height 165.9 (9.9) cm). Right leg stance, swing, and stride duration and stride length, and stride velocity were concurrently assessed with motion captu…
RHINASTHMA-Children: A new quality of life tool for patients with respiratory allergy
2017
Background Specific instruments for health-related quality of life (HRQoL) assessment in adolescents with rhinoconjunctivitis or asthma are available. None of them evaluates rhinitis and asthma together, although they often coexist. Our aim was to validate a HRQoL questionnaire for adolescents with rhinoconjunctivitis, asthma, or both. Methods A pool of 38 items covering the main symptoms and problems related to respiratory allergy was generated based on literature review, clinical experience, and unstructured interviews to 54 adolescents. The items were randomly listed and presented to 88 consecutive outpatients (44 M; mean age 15.2 ± 3.1). Patients had to indicate which item they had expe…
Structural validity of the Finnish Manchester-Oxford Foot Questionnaire (MOXFQ) using the Rasch model.
2019
Background: The 16-item patient-reported Manchester-Oxford Foot Questionnaire (MOXFQ) with subscales of pain, social interactions, and walking/standing has been claimed for strongest scientific evidence in measuring foot and ankle complaints. This study tests the validity of the Finnish MOXFQ for orthopaedic foot and ankle population using the Rasch analysis. Methods: We translated the MOXFQ into Finnish and used that translation in our study. MOXFQ scores were obtained from 183 patients. Response category distribution, item fit, coverage, targeting, item dependency, ability to measure latent trait (unidimensionality), internal consistency (Cronbach's alpha), and person separation index (PS…
Relationship Between Cognitive-Behavioral Impairment and Clinical and Functional Parameters in ALS and Reliability of the Edinburgh Cognitive and Beh…
2019
Background Although it is widely recognized that a high percentage of individuals with amyotrophic lateral sclerosis (ALS) have cognitive and behavioral impairment, the associated clinical and functional parameters remain unknown. ALS is typically assessed via screening tests, such as the Edinburgh Cognitive and Behavioural ALS Screen (ECAS). Objective To investigate the relationship between cognitive-behavioral impairment and other clinical and functional parameters and to compare the assessment results from a set of standardized neuropsychological tests with those from the ECAS. Methods Forty individuals with ALS participated in the study. We assessed attention, memory and learning abilit…
Development and Retest Reliability of a German Version of the Sexual Behaviour Questionnaire (SBQ-G)
2007
A German version of the Sexual Behaviour Questionnaire (SBQ-G) is a short self-rating instrument covering the four domains of sexual function using colloquial words. Frequency of sexual dysfunction was counted and chance-corrected retest reliability was calculated. Eleven women and 12 men participated. Reception of the SBQ-G was favourable and more females than males reported at least moderate sexual dysfunction. Sexual arousal and ability to enjoy sex showed the lowest retest stability. The SBQ-G is a recommendable clinical instrument with high practicability and satisfactory retest reliability. However, gender differences and a high variability of sexual functioning in healthy subjects sh…
Visual Attention Study in Youth With Spastic Cerebral Palsy Using the Event-Related Potential Method
2011
Youth with mild spastic cerebral palsy (n = 14) and a peer control group were compared on an oddball paradigm. Here, visual stimuli were presented with low and high probability and participants were instructed to count in silence the number of rare stimuli. The infrequent stimulus typically elicits an enhanced frontal central N2 and a centroparietal P300 event-related brain potential, reflecting orientation and evaluation of stimulus novelty. No differences in latency and amplitude of the N2–P300 complex were found between the 2 groups, indicating that some fundamental attention processes are intact in youth with mild spastic cerebral palsy.
Test-retest reliability of the Star Excursion Balance Test in primary school children.
2014
Dynamic balance has been considered a fundamental skill at all ages and is required for normal daily tasks, such as walking, running, or other sports activities. The Star Excursion Balance Test (SEBT) has been widely used in recent years to identify dynamic balance deficits and improvements and to predict the risk of lower extremity injury. However, no study has demonstrated the reliability of the SEBT in children while they are performing the test in a physical education session. Reliability is needed in all measurement tools in order to provide repeatable and consistent data.To evaluate the reliability of the SEBT in primary school students in the school setting.Twenty-four healthy childr…
