Early adolescence is an important period for assuring adequate calcium intake to achieve optimal bone health. This study was conducted to develop a measure of psychosocial constructs likely to be associated with young adolescent girls' consumption of high-calcium foods and to evaluate the test-retest reliability and factor structure of the measure. Methods involved: (a) generating a pool of ite...
OBJECTIVE Studies of dental caries should account for sugar consumption as a potential confounder or effect modifier of other exposure-caries associations. The purpose of this study was to assess the reliability of a sugar consumption score for rural Haiti through correlation of test-retest scores derived from a structured, interviewer-administered questionnaire. METHODS A structured, intervi...
The purpose of this study was to assess the reproducibility (test-retest reliability and agreement) and concurrent validity of the Myotest for measuring step frequency (SF) and ground contact time (GCT) in recreational runners. Based on a within-subjects design (test and retest), SF and GCT of 14 participants (11 males, 3 females) were measured at three different running speeds with the Myotest...
For DSM-V, simple dimensional measures of disorder severity will accompany diagnostic criteria. The current studies examine convergent validity and test-retest reliability of two potential dimensional indicators of worry severity for generalized anxiety disorder (GAD): percent of the day worried and number of worry domains. In study 1, archival data from diagnostic interviews from a community s...
OBJECTIVE The rate at which people obtain reliably improved or declined cognitive test scores when retested, in the absence of a change in clinical condition, is largely unknown. The purpose of this study was to illustrate the prevalence of statistically reliable change scores on memory test batteries in healthy adults and older adults. METHOD Participants included three adult and older adult...
The forced swim test (FST) is a pre-clinical test to short and long term treatment with antidepressant drugs (ADT), which requires between-subject designs. Herein a modified protocol of the FST using within-subject design (repeated rat-FST) was evaluated. Male Wistar rats were submitted to 15 min of swimming (Day 1: pretest) followed by three subsequent 5 min-swimming tests one week apart (Day ...
AIMS Reliabilities of the work environment questionnaire Copenhagen Psychosocial Questionnaire (COPSOQ) have previously been estimated by Cronbach's alpha, but since the internal consistency assumption may not apply to all COPSOQ scales, Cronbach's alpha may underestimate true reliability. This study aims to evaluate reliability in a test-retest design. METHODS We analyzed postal questionnair...
Altogether 553 children (195 first graders, mean age 6.8 years, and 358 third graders, mean age 8.7 years) participated in the development of a self-report measure to assess the intensity of children's pain. The first step was the derivation, from children's drawings of facial expressions of pain, of 5 sets of 7 schematic faces depicting changes in severity of expressed pain from no pain to the...
BACKGROUND Previous research has not compared the psychometric properties of diagnostic interviews of community samples and clinically referred subjects within a single study. As part of a multisite cooperative agreement study funded by the National Institute of Mental Health, 97 families with clinically referred children and 278 families identified through community sampling procedures partici...
The SCAN is a popular screening test that was developed to provide a rapidly administered, standardized method for determining the potential of central auditory processing disorder (CAPD) in children between the ages of 3 and 11 years. It can be administered in 20 minutes with a portable stereo cassette player and contains three subtests: filtered words (FW), auditory figure ground (AFG), and c...
