Abstract The present study evaluated the psychometric properties of Serbian Smartphone Application-Based Addiction Scale (SABAS) and original English version same scale administered to a Serbian-speaking sample. In Study 1, 599 participants completed SABAS, with 189 having both test retest data. Results suggested good internal consistency ( α = .81) test–retest reliability ICC .795, p < .001...

Objective: To investigate the intra – rater and inter reliability of cranio cervical flexion test in symptomatic subjects. Background study: Neck flexor muscles endurance was negatively correlated with pain dysfunction. Cranio protocol has been advocated to train muscle performance at present there is no consensus most effective method. The CCFT a clinical neuromotor control deep spine. Methodo...

We investigated retest learning (i.e., performance improvement through retest practice) in the absence of item-specific effects (i.e., learning through memorizing or becoming familiar with specific items) with older adults. Thirty-one older adults (ages 60-82 years, M = 71.10, SD = 6.27) participated in an eight-session self-guided retest program. To eliminate item-specific effects, parallel ve...

The Test of In-Hand Manipulation (TIHM; Case-Smith, 2000) is a five-task test that uses a 9-hole pegboard to examine 2 key components of in-hand manipulation: rotation and translation with stabilization. The authors used Rasch modeling to examine the TIHM's construct validity, interrater reliability, and test-retest reliability in 45 typically developing children ages 5.5 years to 6.5 years. A ...

The role of serotonin in CNS function and in many neuropsychiatric diseases (e.g., schizophrenia, affective disorders, degenerative dementias) support the development of a reliable measure of serotonin receptor binding in vivo in human subjects. To this end, the regional distribution and intrasubject test-retest variability of the binding of [18F]altanserin were measured as important steps in t...

abstract introduction: standardized tests in speech therapy mostly focus onlanguage structure rather than the use of language in social context. so, there is a clear need for instruments to assess pragmatic aspects of language. children’s communicationchecklist (ccc) and its revised version, ccc-2, was developed to address this need, however, its psychometric features are unknown in iran. the c...

The objectives of this study were to design a field test based on the Conconi protocol to determine the ventilatory threshold of rowers and to test its reliability and validity. A group of sixteen oarsmen completed a modified Conconi test for on-water rowing. The reliability of the detection of the heart rate threshold was evaluated using heart rate breaking point in the Conconi test and retest...
