The Achievement Motives Scale (AMS) is a well established and frequently used scale to assess hope of sucess and fear of failure. In 3 studies with German-speaking samples (N=3523, N=132, N=126), the authors developed a revised form of the AMS using confirmatory factor analysis. As found in previous research, the original 30-item set of the AMS did not provide an acceptable fit to a 2-factor mo...

BACKGROUND Modern psychometric methods based on item response theory (IRT) can be used to develop adaptive measures of health-related quality of life (HRQL). Adaptive assessment requires an item bank for each domain of HRQL. The purpose of this study was to develop item banks for five domains of HRQL relevant to arthritis. METHODS About 1,400 items were drawn from published questionnaires or ...

OBJECTIVES The aim of this study was to verify psychometric properties of the Polish version of the Job-related Affective Well-being Scale (JAWS). Specifically, theoretical 4-factor structure (based on the dimensions of pleasure and arousal) and reliability of the original - 20-item JAWS (van Katwyk et al., 2000) and the shortened - 12-item (Schaufeli and Van Rhenen, 2006) versions were tested....

purpose :   the present study investigated the psychometric properties of a malaysian adapted brunel mood scale.   methods:   the questionnaire was administered to 355 young sport athletes with a mean age of 14.69 + 1.70 years. confirmatory factor analysis (cfa) and cronbach's alpha were used to determine the factorial validity and the internal consistency of the questionnaire respectively. res...

Person fit statistics are frequently used to detect aberrant behavior when assuming an item response model generated the data. A common statistic, $$l_z$$ , has been shown in previous studies perform well under a myriad of conditions. However, it is well-known that does not follow standard normal distribution using estimated latent trait. As result, corrections called $$l_z^*$$ have proposed li...

BACKGROUND The Dermatology Life Quality Index (DLQI) is the most widely used measure of health-related quality of life (HRQoL) associated with skin disease. Recently, the psychometric properties of the DLQI have caused some controversy because the instrument appears not to meet the requirements of modern test theory. The purpose of this study was to assess whether these psychometric issues also...

OBJECTIVES To develop a one-dimensional version of the 22-item Zarit Caregiver Burden Interview (ZBI) by applying item response theory approaches. METHODS The answers to the 22-item ZBI of 241 caregivers participating in a clinical trial were analyzed 1) with a Mokken nonparametric item response theory analysis to ascertain the dimensional structure underlying the scale and obtain a one-dimen...
