A validity and reliability study of assessment and screening for sustained withdrawal reaction in infancy: The Alarm Distress Baby scale,

Antoine Guedeney
Sustained withdrawal behavior in infancy is an important alarm signal to draw attention to both organic and relationship disorders. A withdrawal scale, the Alarm Distress Baby scale (ADBB), for infants between 2 and 24 months of age was built. This article describes the construction of the scale and the assessment of its psychometric properties. The ADBB has good content validity, based on the advice of seven experts. The scale has good criterion validity: first, as a measure of the infant's withdrawal reaction, with a very good correlation between nurse and pediatrician on the ADBB (rs = 0.84), and second, as a screening procedure for detecting the developmental risk of the infant. The cutoff score of 5 with a sensitivity of 0.82 and a specificity of 0.78 was determined to be optimal for screening purposes. The scale has good construct validity, with good convergent validity with both the Spitz (1951) and the Herzog & Rathbun (1982) lists of symptoms of infant depression (rs = 0.61 and 0.60, respectively). Exploratory factor analysis showed two different factors, consistent with the scale's construct. Reliability was satisfactory with good internal consistency for both subscales (the Cronbach , = 0.80 for the first subscale and 0.79 for the second) and for the global scale (, = 0.83). The test-retest procedure showed good stability over time (rs = 0.90 and 0.84 for the two different raters). The scale could be used in different clinical settings, provided a sufficient level of social stimulation is given to the infant in a relatively brief period of time. The scale can be used by nurses and psychologists or by medical doctors after a short period of training. 2001 Michigan Association for Infant Mental Health. [source]

Psychometric properties of an interviewer-administered version of the Kessler Psychological Distress scale (K10) among Dutch, Moroccan and Turkish respondents

T. Fassaert
Abstract The Kessler Psychological Distress scale (K10) is an instrument that is widely used to screen for mental disorders, but information is lacking on its psychometric qualities in non-Western samples. This study used a population-based sample (N = 725) to assess the reliability and validity of the K10 across ethnic groups in an urban area. The results were generally supportive of the K10 as a reliable and valid instrument to screen for anxiety and depression in all three groups. Cronbach's alpha was high (0.93) and the results indicated the existence of a solid single factor structure. Item bias in relation to ethnic background was minor. In each group, there was good criterion validity with respect to one-month DSM-IV diagnosis for depressive and/or anxiety disorder. The results nevertheless highlight the importance of cross-cultural validation, as we found different cut-off values for ethnic subgroups to obtain optimal sensitivity and specificity for detecting depressive and/or anxiety disorders.

Distinguishing between task and contextual performance for nurses: development of a job performance scale

Jaimi H. Greenslade
Abstract Title.,Distinguishing between task and contextual performance for nurses: development of a job performance scale Aim., This paper is a report of a development and validation of a new job performance scale based on an established job performance model. Background., Previous measures of nursing quality are atheoretical and fail to incorporate the complete range of behaviours performed. Thus, an up-to-date measure of job performance is required for assessing nursing quality. Methods., Test construction involved systematic generation of test items using focus groups, a literature review, and an expert review of test items. A pilot study was conducted to determine the multidimensional nature of the taxonomy and its psychometric properties. All data were collected in 2005. Findings., The final version of the nursing performance taxonomy included 41 behaviours across eight dimensions of job performance. Results from preliminary psychometric investigations suggest that the nursing performance scale has good internal consistency, good convergent validity and good criterion validity. Conclusion., The findings give preliminary support for a new job performance scale as a reliable and valid tool for assessing nursing quality. However, further research using a larger sample and nurses from a broader geographical region is required to cross-validate the measure. This scale may be used to guide hospital managers regarding the quality of nursing care within units and to guide future research in the area. [source]

Willingness to pay for a hearing aid: comparing the payment scale and open-ended question

Janneke P. C. Grutters MSc
Abstract Rationale & objectives, Different question formats elicit different willingness-to-pay (WTP) results, but there is no consensus on which method elicits the most valid WTP. In spite of the methodological controversies, WTP is a potentially valuable tool in health economics to value health services. Our general objective was to provide additional evidence on the validity of two WTP elicitation formats: the open-ended question and the payment scale. Methods, We elicited WTP for a hearing aid among hearing aid users (n = 108), using both a payment scale and an open-ended question. We compared the results from both formats. We tested criterion validity by comparing both formats with the actual out-of-pocket payment. Construct validity was tested by examining whether WTP was consistent with positive income elasticity. Results, The WTP results elicited with the payment scale and open-ended question were not statistically significantly different. Both formats showed good criterion validity, although the open-ended question showed a stronger association with the actual out-of-pocket payment. The open-ended format showed better construct validity, as it was influenced by family income. Conclusion, The results of the present study showed that the open-ended question was more valid than the payment scale question. We, therefore, recommend that in future WTP studies on hearing aids the open-ended question is used to directly elicit WTP values. The same recommendation may apply to other studies where respondents are familiar with costs or payments for the intervention under evaluation. [source]
