Reliability and validity of the Youth Self-Report, Bangladesh version

Takashi Izutsu
Abstract The objectives of this study were to develop the Bangladesh version of the Youth Self-Report (YSR), and assess its reliability and validity in an adolescent population in Dhaka city, Bangladesh. One-hundred-and-eighty-seven boys (mean age: 14.6 years, SD: 2.1) and 137 girls (mean age: 15.2 years, SD: 2.0) from residential areas, and 27 boys (mean age: 17.0, SD: 1.4) and 14 girls (mean age: 15.4, SD: 2.8) from a psychiatric hospital, all within the range of 11,18 years, were interviewed using a questionnaire that consisted of the Bangla translation of the YSR and other questions. Thirty-eight randomly selected adolescents were administered the same questionnaire one week after the first administration. All the core scores and most of the subscales showed high internal consistency other than small item-number subscales, and satisfactory test- retest reliability. Good discriminant validity was shown for most of the scale scores. This study showed that the Bangla translation of the YSR had sufficient reliability and validity for use in Bangladesh. The cutoff scores of the scales were higher for the Bangla version than for the original English version, and further studies exploring this point would be an asset.

Validating the organizational climate measure: links to managerial practices, productivity and innovation

Malcolm G. Patterson
This paper describes the development and validation of a multidimensional measure of organizational climate, the Organizational Climate Measure (OCM), based upon Quinn and Rohrbaugh's Competing Values model. A sample of 6869 employees across 55 manufacturing organizations completed the questionnaire. The 17 scales contained within the measure had acceptable levels of reliability and were factorially distinct. Concurrent validity was measured by correlating employees' ratings with managers' and interviewers' descriptions of managerial practices and organizational characteristics. Predictive validity was established using measures of productivity and innovation. The OCM also discriminated effectively between organizations, demonstrating good discriminant validity. The measure offers researchers a relatively comprehensive and flexible approach to the assessment of organizational members' experience and promises applied and theoretical benefits.

Cross-Validation and Discriminant Validity of Adolescent Health Promotion Scale Among Overweight and Nonoverweight Adolescents in Taiwan

Mei-Yen Chen
ABSTRACT This study used cross-validation and discriminant analysis to evaluate the construct and discriminant validity of Adolescent Health Promotion (AHP) scale between the overweight and nonoverweight adolescents in Taiwan. A cross-sectional survey method was used and 660 adolescents participated in this study. Cluster and discriminant analyses were used to analyze the data. Our findings indicate that the AHP is a valid and reliable scale to discriminate between the health-promoting behaviors of overweight and nonoverweight adolescents. For the total scale, cluster analyses revealed two distinct patterns, which we designated the healthy and unhealthy groups. Discriminate analysis supported this clustering as having good discriminant validity, as nonoverweight adolescents tended to be classified as healthy, while the overweight tended to be in the unhealthy group. In general, overweight adolescents practiced health-related behaviors at a significantly lower frequency than the nonoverweight. These included exercise behavior, stress management, life appreciation, health responsibility, and social support. These findings can be used to further develop and refine knowledge of adolescent overweight and related strategies for intervention. [source]

ORIGINAL RESEARCH,OUTCOMES ASSESSMENT: Validation of the Female Sexual Distress Scale-Revised for Assessing Distress in Women with Hypoactive Sexual Desire Disorder

Leonard DeRogatis PhD
ABSTRACT Introduction., The concept of sexually related personal distress is currently central to the diagnosis of all female sexual dysfunctions (FSD). In the current study, we have focused on validating a slightly revised version of the Female Sexual Distress Scale (FSDS), the FSDS-Revised (FSDS-R), to enhance the sensitivity of the instrument with patients suffering from hypoactive sexual desire disorder (HSDD). In addition, we have attempted to extend the validation generalizability of the scale by demonstrating that both instruments possess reliability and discriminative validity in premenopausal women with HSDD. Aim., To assess the validity of the revised version of the FSDS, the FSDS-R, for measuring sexual distress in women with HSDD. Methods., A prospective methodological study carried out at 27 centers in North America enrolled 296 women aged 18,50 years with HSDD, another female sexual dysfunction (FSD), or no FSD. The subjects completed the FSDS-R at baseline, day 7, and day 28, with a 30-day recall at baseline and with a 7-day recall on days 7 and 28. Main Outcome Measures., Receiver operating characteristic (ROC) analyses of FSDS, FSDS-R, and FSDS-R item 13 were used for the differentiation of HSDD from no FSD, while intraclass correlation coefficient (ICC) was used to estimate test,retest reliability. Cronbach's coefficient alpha was used to measure the internal consistency of the FSDS-R and Pearson's correlation coefficient to assess FSDS, FSDS-R, and FSDS-R item 13 with different recall periods (7 and 30 days). Results., Mean total FSDS, FSDS-R, and FSDS-R item 13 scores with either recall period were significantly higher (P < 0.0001) in women with FSD or HSDD than in women with no FSD, showing both tests had discriminant validity. ROC analysis confirmed these findings, while an ICC of >0.74 showed the test,retest reliability of both scales, including FSDS-R item 13 alone, and Cronbach's coefficient alpha of >0.86 confirmed the internal consistency of both tests. Conclusions., Consistent with the FSDS, the FSDS-R demonstrated good discriminant validity, high test,retest reliability, and a high degree of internal consistency in measuring sexually related personal distress in women with HSDD. FSDS-R item 13 alone also demonstrated good discriminant validity and test,retest reliability. DeRogatis L, Clayton A, Lewis-D'Agostino D, Wunderlich G, and Fu Y.

The Finnish version of The National Institutes Of Health Chronic Prostatitis Symptom Index correlates well with the visual pain scale: translation and results of a modified linguistic validation study

M.J. Leskinen
Authors from Finland have assessed a version in their language of the National Institutes of Health-Chronic Prostatitis Symptom Index; they found that their translated version was valid and easily understandable in the management of the symptoms of chronic pelvic pain syndrome. They felt it should be used as a primary outcome measure in studies with these patients. There are three papers in this issue relating to the effect of drugs on LUTS; the first of these is a pooled analysis of three double-blind placebo-controlled studies into the safety and efficacy of the 10 mg dose of alfuzosin. The second evaluates the effect on quality-of-life issues of treatment with dutasteride. Finally, authors from Australia compare the effect of a Serenoa repens extract with placebo for LUTS. OBJECTIVES To provide a fluent and easily comprehensible Finnish version of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and to study its linguistic validity and correlation with a visual pain scale (VAS). PATIENTS AND METHODS The double-back translation method with two interim modifications was used to produce the Finnish version of the NIH-CPSI. The validity was tested by presenting the questionnaire to 155 men with clinically confirmed chronic pelvic pain syndrome (CPPS) and 12 controls with no previous urological symptoms. Convergent validity of the NIH-CPSI was tested by determining the correlation between the Finnish NIH-CPSI and VAS. Patients' and urologists' opinions about the utility of the Finnish NIH-CPSI were also reviewed. RESULTS The total Finnish NIH-CPSI scores and the pain domain and voiding symptom domain scores differed significantly (P < 0.001) between the groups, suggesting good discriminant validity of the symptom index. The NIH-CPSI scores correlated well with the VAS (Pearson's correlation 0.76). The preciseness and comprehensibility of the questionnaire were consistently evaluated to be ,good' or ,excellent' both by patients and urologists. CONCLUSIONS The Finnish version of the NIH-CPSI is valid and easily comprehensible for measuring CPPS symptoms. In addition, it provides good discriminant and convergent validity in distinguishing CPPS symptoms and should be used as primary outcome measure in CPPS studies. [source]

Self-perceived health and burden of diabetes in teenagers with type 1 diabetes: psychometric properties of the Swedish measure ,Check your health'

G Viklund
Abstract The aim of this study was to test the psychometric properties of the instrument ,Check your health' in teenagers with type 1 diabetes. The instrument measures ,self-reported health' and ,burden of diabetes'. A convenience sample of 199 teenagers, 12,17 years of age, completed the questionnaires ,Check your health' and DisabKids when visiting the diabetes clinic. Forty-seven patients completed the questionnaires at home a second time. In the reliability test, the correlation between test and retest was found to be satisfactory, (0.94,0.62, except for social burden, 0.41). Convergent validity was moderate (0.62,0.38), while the instrument showed good discriminant validity. Self-reported health and burden of diabetes were different in boys and girls, in patients with good or poor metabolic control or who reported high and low disease severity. The domain burden of diabetes turned out to be very sensitive. Conclusion:, The instrument ,Check your health' showed clinical utility in teenagers with diabetes. Reliability and validity tests of the measure showed promising results in Swedish teenagers, and it can probably be used in clinical settings. To further strengthen the convergent validity, it should be compared with other QoL instruments, and to obtain normative values, it has to be used in a larger context. [source]
