Valid Predictors (valid + predictor)
Selected AbstractsAssessment of the importance of glenohumeral peripheral mechanics by practicing physiotherapistsPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 3 2007Kenneth Kirby Abstract Background and Purpose.,Physiotherapists develop clinical reasoning theories and applied manual therapy skills through a variety of educational exposures. No studies have assessed the importance of selected theories such as the convex,concave rule, capsular pattern and scapulohumeral rhythm during clinical decision-making by physiotherapists. The present study investigated which variables physiotherapists considered were associated with the importance of these theories during practice and investigated physiotherapists' perception of translational motion biomechanics of the glenohumeral (GH) joint.,Method.,Six hundred and sixty physiotherapists in the USA volunteered to participate in this study. Using ologit regression analyses, the identifier themes and clinical background characteristics were associated with importance of peripheral biomechanics in manual therapy application and reliability/validity of the scapulohumeral rhythm theory in predicting pathological sequences of the shoulder complex. An intraclass correlation coefficient (ICC) was used to determine agreement regarding necessary translation of the GH joint for normal movement.,Results.,The majority of physiotherapists indicated that all theories were important or very important during treatment decision-making and reported frequent utilization. Regression models identified that the importance placed on peripheral biomechanics was negatively influenced by academic qualification (bachelors and masters degrees) and gender (men were less likely to report that scapulohumeral rhythm was a reliable/valid predictor of shoulder pathology). ICC values identified excellent agreement among clinicians regarding translational motion.,Conclusions.,The importance of biomechanics of the periphery for use, validation and frequency was based heavily on adoption of selected theories of glenohumeral movements despite evidence that suggests the theories lack validity.

[source] Personality and Performance at the Beginning of the New Millennium: What Do We Know and Where Do We Go Next?INTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 1-2 2001Murray R. Barrick As we begin the new millennium, it is an appropriate time to examine what we have learned about personality-performance relationships over the past century and to embark on new directions for research. In this study we quantitatively summarize the results of 15 prior meta-analytic studies that have investigated the relationship between the Five Factor Model (FFM) personality traits and job performance. Results support the previous findings that conscientiousness is a valid predictor across performance measures in all occupations studied. Emotional stability was also found to be a generalizable predictor when overall work performance was the criterion, but its relationship to specific performance criteria and occupations was less consistent than was conscientiousness. Though the other three Big Five traits (extraversion, openness and agreeableness) did not predict overall work performance, they did predict success in specific occupations or relate to specific criteria. The studies upon which these results are based comprise most of the research that has been conducted on this topic in the past century. Consequently, we call for a moratorium on meta-analytic studies of the type reviewed in our study and recommend that researchers embark on a new research agenda designed to further our understanding of personality-performance linkages. [source] The predictive and interactive effects of equity sensitivity in teamwork-oriented organizationsJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 3 2001Mark N. Bing Many studies have investigated the relationship between equity sensitivity and other variables of organizational importance. Although theoretical grounds support a link between equity sensitivity and job performance, to date no studies have found equity sensitivity to be a valid predictor of non self-reported job performance in field research. The two field studies reported here empirically support this link and demonstrate that equity sensitivity may also interact with personality traits in predicting job performance. Limitations of the current investigations and future research are discussed. Copyright © 2001 John Wiley & Sons, Ltd. [source] SELF- VERSUS OTHERS' RATINGS AS PREDICTORS OF ASSESSMENT CENTER RATINGS: VALIDATION EVIDENCE FOR 360-DEGREE FEEDBACK PROGRAMSPERSONNEL PSYCHOLOGY, Issue 4 2002Paul W. B. Atkins Although 360-degree feedback programs are rapidly increasing in popularity, few studies have examined how well ratings from these programs predict an independent criterion. This study had 2 main aims: First, to examine the validity of ratings from a 360-degree feedback program using assessment center ratings as an independent criterion and to determine which source (i.e., self, supervisor, peers, or subordinates) provided the most valid predictor of the criterion measure of competency. Second, to better understand the relationship between self-observer discrepancies and an independent criterion. The average of supervisor, peer, and subordinate ratings predicted performance on the assessment center, as did the supervisor ratings alone. The self-ratings were negatively and nonlinearly related to performance with some of those who gave themselves the highest ratings having the lowest performance on the assessment center. Supervisor ratings successfully discriminated between overestimators but were not as successful at discriminating underestimators, suggesting that more modest feedback recipients might be underrated by their supervisors. Peers overestimated performance for poor performers. Explanations of the results and the implications for the use of self-ratings in evaluations, the design of feedback reports, and the use of 360-degree feedback programs for involving and empowering staff are discussed. [source] Long-Term Follow-Up of Patients with Syncope Evaluated by Head-Up Tilt TestANNALS OF NONINVASIVE ELECTROCARDIOLOGY, Issue 2 2010Giulia Domenichini M.D. Background: Clinicians may be tempted to consider a positive head-up tilt test (HUTT) an unfavorable prognostic indicator. We investigated whether results of routine HUTT predict long-term recurrence of syncope. Methods: We analyzed syncope recurrence at long-term among 107 patients (mean age 51 ± 20 years) receiving HUTT for diagnostic evaluation of unexplained/suspected neurocardiogenic syncope in our Institute. Results: HUTT was positive in 76 patients (vasodepressive response, n = 58; cardioinhibitory, n = 5; mixed, n = 13). During a median follow-up of 113 months (range, 7,161), 34 (32%) patients experienced recurrence (24 [32%] with positive HUTT during 110 months (7,159); 10 [32%] with negative HUTT during 120 [22,161] months). Actuarial freedom from recurrence at 10 years did not significantly differ for patients with positive/negative test results (after passive/active phases) or with different positive response patterns (vasodepressive, cardioinhibitory, mixed). By contrast, history of >4 syncopes in the 12 months preceding HUTT stratified risk of recurrence, irrespective of HUTT positivity/negativity. At Cox proportional hazards analysis, history of >4 syncopes in the 12 months preceding HUTT was the single independent risk factor for recurrence both in the overall study population (HR, 1.7; 95% CI, 1.07,2.69) and within the subset of patients who tested positive (HR, 1.83; 95% CI, 1.07,3.17). Conclusions: This long-term follow-up study reinforces the concept that a positive HUTT should not be considered an unfavorable prognostic indicator; frequency of recent occurrences may be a more valid predictor.

Participants were 236 eighth-grade students (134 females and 102 males) in the classrooms of 17 English teachers. Students completed 1-, 2-, and 3-minute reading aloud and 2-, 3-, and 4-minute maze selection tasks. The relation between performance on the CBMs and the state reading test were examined. Results revealed that both reading aloud and maze selection were reliable and valid predictors of performance on the state standards tests, with validity coefficients above .70. An exploratory follow-up study was conducted in which the growth curves produced by the reading-aloud and maze-selection measures were compared for a subset of 31 students from the original study. For these 31 students, maze selection reflected change over time whereas reading aloud did not. This pattern of results was found for both lower- and higher-performing students. Results suggest that it is important to consider both performance and progress when examining the technical adequacy of CBMs. Implications for the use of measures with secondary-level students for progress monitoring are discussed. [source] A SITUATIONAL JUDGMENT TEST OF PERSONAL INITIATIVE AND ITS RELATIONSHIP TO PERFORMANCEPERSONNEL PSYCHOLOGY, Issue 2 2009RONALD BLEDOW Although situational judgment tests have been found to be valid predictors of performance, they have rarely been used to measure particular constructs. In this study, we apply the situational judgment test method to the measurement of personal initiative, a construct defined as situated action. We used respondents' situated preferences in mental simulations of work scenarios as formative indicators of their overall level of personal initiative at work. Results from a validation study showed that the situational judgment test of personal initiative (SJT-PI) had adequate validity and complemented a Likert-type self-report measure of personal initiative in predicting behavioral criteria. Situated preferences for personal initiative were hypothesized to be proximal predictors of actual behavior and were accordingly found to mediate the relationship between generalized self-efficacy, felt responsibility, and actual behavior. Furthermore, situated preferences for personal initiative could be differentiated empirically from organizational citizenship behavior. We conclude that situational judgment tests are a promising method for measuring personal initiative and may be a general means of improving the validity of measurement in organizations. [source] Predictors of depressive symptomatology of geriatric patients with lung cancer,a longitudinal analysisPSYCHO-ONCOLOGY, Issue 1 2002M.E. Kurtz Background: Lung cancer is a major health problem throughout the world. It is the leading cause of cancer-related death in men and women in the USA, with a 5-year survival rate of only 14%. It has been hypothesized that variables such as physical and social functioning, cancer-related symptomatology, comorbid conditions, cell type, and treatment are valid predictors of the psychological response to a diagnosis of lung cancer. Methods: As part of a larger longitudinal study, 211 patients, 65 years of age or older, with an incident diagnosis of lung cancer, were recruited from 23 sites within a midwestern state. Repeated measures analysis of variance techniques were used to analyse how age, gender, comorbid conditions, stage of disease, cell type, as well as the time-dependent variables symptoms, physical functioning, social functioning, and treatment predict depressive symptomatology at four assessments over the first year following diagnosis. Results: Social functioning (p<0.0001), symptoms severity (p<0.0001) and radiation treatment (p=0.017) were significant predictors of depressive symptomatology, with more symptoms and more restricted social functioning generally corresponding to higher levels of depressive symptomatology. Patients who had not received radiation treatment were more depressed than those who had received treatment at least 40 days prior to the interview. Conclusions: At a clinical level of patient care, these findings mandate early identification of psychosocial difficulties experienced, an individualized symptom management plan and the application of other interventions, such as information giving, reassurance and referral to other resources.

H. Wyffels Summary We investigated the ability of pulse pressure variation and stroke volume variation to predict fluid responsiveness during mechanical ventilation in patients undergoing open chest surgery by comparing their respective correlations with cardiac output changes induced by leg elevation. Serial leg elevation manoeuvres were performed before and after sternotomy in 15 patients scheduled for elective off-pump coronary bypass surgery. Under closed chest conditions, both pulse pressure variation and stroke volume variation correlated well with the induced cardiac output changes (r = 0.856, p = 0.002 and r = 0.897, p = 0.0012, respectively). These correlations were lost for both parameters following sternotomy. Our data show that pulse pressure variation and stroke volume variation are valid predictors of fluid responsiveness under closed chest conditions but that this property no longer holds when the chest is open. [source] Cardiopulmonary exercise testing as a risk assessment method in non cardio-pulmonary surgery: a systematic reviewANAESTHESIA, Issue 8 2009T. B. Smith Summary This study reviews the predictive value of maximum oxygen consumption () and anaerobic threshold, obtained through cardiopulmonary exercise testing, in calculating peri-operative morbidity and mortality in non-cardiopulmonary thoraco-abdominal surgery. A literature review provided nine studies that investigated either one or both of these two variables across a wide range of surgical procedures. Six of the seven studies that reported sufficiently detailed results on peak oxygen consumption and four of the six studies that reported sufficiently detailed results on anaerobic threshold found them to be significant predictors. We conclude that peak oxygen consumption and possibly anaerobic threshold are valid predictors of peri-operative morbidity and mortality in non-cardiopulmonary thoraco-abdominal surgery. These indicators could potentially provide a means of allocating increased care to high-risk patients. [source] | |||||||||||||
