The Short Form-36 (SF-36) health questionnaire has been put forward as a general measure of outcome in health care and has been evaluated in several recent studies in the UK. We report its use in three groups of patients after spinal operations and have compared it with the Oswestry and Low Back Pain disability scales. There was a significant correlation between all variables of the SF-36 and t...

The creation and adaptation of scales or inventories assessing specific circadian typologies has been a predominant focus within the field of chronopsychology. The present study addressed the psychometric properties of two scales of morningness-eveningness: the Morningness Composite Scale (CS; Smith, Reilly, & Midkiff, 1989) and the Early/Late Preferences Scale (PS; Smith, Folkard, Schmieder, P...

The Eysenck Personality Questionnaire was administered to 139 females and 123 males. Scale statistics were obtained and hierachial factor analyses were performed. The P scale was found to have low internal consistency reliabilities and to covary with the L scale in the female subsample. Factor analyses showed recovery of E scale items in a secondary factor, Social Extraversion, without an impul...

The objective of the present study was to construct and validate a short-form version of the Self-Compassion Scale (SCS). Two Dutch samples were used to construct and cross-validate the factorial structure of a 12-item Self-Compassion Scale-Short Form (SCS-SF). The SCS-SF was then validated in a third, English sample. The SCS-SF demonstrated adequate internal consistency (Cronbach's alpha ≥ 0.8...

We evaluated the psychometric properties of the London Measure of Unplanned Pregnancy among Indian women using classical methods and Item Response Modeling. The scale exhibited good internal consistency and internal structure, with overall scores correlating well with each item's response categories. Items performed similarly for pregnant and non-pregnant women, and scores decreased with increa...

OBJECTIVE The objective of this study was to develop a validated and reliable questionnaire to measure consumer knowledge regarding safe practices to prevent microbiological contamination in restaurants and commercial kitchens. METHODS Non-probabilistic samples of individuals were interviewed in the city of Campinas, Brazil. Questionnaire items were elaborated and reviewed. Content and constr...

This study describes the development and preliminary psychometric properties of a scale for measuring hypnotic response in clinical hypnosis sessions. The Hypnotic State Assessment Questionnaire (HSAQ), a brief, multidimensional measure of hypnotic response during clinical sessions of hypnosis, is intended to facilitate supervision of hypnosis trainees and to document subjects' response in clin...

The purpose of this study was to examine the psychometric properties of a new measure of client motivation for therapy, the Client Motivation for Therapy Scale. This scale is designed to measure client's Intrinsic Motivation, four forms of regulation for Extrinsic Motivation (integrated, identified, introjected, and external regulation), and Amotivation for therapy. These subscales correspond t...

Previous confirmatory factor analytic research that has examined the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. An alternative model that has not yet been examined for the WAIS-IV is the bifactor mod...

Bayesian internal consistency and its Bayesian credible interval (BCI) are developed and Bayesian internal consistency and its percentile and normal theory based BCIs were investigated in a simulation study. Results indicate that the Bayesian internal consistency is relatively unbiased under all investigated conditions and the percentile based BCIs yielded better coverage performance. Introduct...
