This investigation seeks to establish the psychometric properties of an adapted measure of experiential avoidance (EA) in the parenting context by assessing its relation to other parenting constructs and psychosocial correlates of child anxiety in a clinical sample. Participants were 154 children (90 female, 64 male) diagnosed with anxiety disorders and their parents (148 mothers, 119 fathers)....

Researchers have identified trajectories of pain derived using statistical techniques on longitudinal data. These trajectories have potential to be of use clinically but the repeated data collection required is currently impractical for such situations. Our aim was to investigate the validity of a self-report (Visual Trajectories Questionnaire-Pain) for pain. Analysis included participants from...

INTRODUCTION Despite the widespread use of deprivation indices in public health, they are rarely explicitly or extensively validated, owing to the complex nature of the exercise. METHODS Based on the proposals of British researchers, we sought to validate Quebec's material and social deprivation index using criteria of validity (content, criterion and construct validity), reliability and resp...

OBJECTIVES Three studies were undertaken to establish the reliability and validity of the Scottish physical activity questionnaire (SPAQ), developed to aid seven day recall of leisure and occupational physical activity. METHODS To establish reliability, SPAQs (n = 34) were completed on a Monday and the following Wednesday. Thus each questionnaire measured four identical days. To establish con...

Rising standards for accurately inferring the impact of development projects has not been matched by equivalently rigorous procedures for guiding decisions about whether and how similar results might be expected elsewhere. These ‘external validity’ concerns are especially pressing for ‘complex’ development interventions, in which the explicit purpose is often to adapt projects to local contextu...

The Thurstone Word Fluency Test (TWFT) is a widely used neuropsychological instrument. However, data regarding its psychometric properties are lacking. The results of the present study suggest that the TWFT possesses excellent test-retest and inter-rater reliability, in addition to good construct validity. However, its criterion validity is limited by its lack of specificity and sensitivity. Th...

abstract the present study aims to evaluate efl course contents used in language schools and institutes in teh-ran. to that end, 230 participants in tehran were conveniently sampled. at the outset of the study, two questionnaires were given to all groups, and according to their responses, the data were analyzed. each of the questionnaires was given to participants individually. each group had...

    Consequential validity, a component of construct validity as a unified concept introduced by Messick(1989), deals with the impacts of tests on teaching, learning, individual test takers, teachers, society, and educational system within a country. Although the impacts of language tests on teaching and learning have been somehow studied, the consequences of ESP tests on individual test taker...
