This study extends the literature on interview validity by attempting to create a structured employment interview with both construct- and criterion-related validity. For this study, a situational interview was developed with the specific purpose of enhancing the interview's construct validity while retaining the interview's predictive power. To enhance the construct validity, two guidelines were applied to the creation of the interview based on previous research in interview and assessment center literature limit the number of applicant characteristics to be rated to 3; and (2) ensure that the dimensions to be measured are conceptually distinct. Based on these two guidelines, three constructs were chosen for assessment of real estate sales agents extraversion, proactive personality and customer orientation. The critical incident technique was used to develop six interview items. To test the construct validity of the interview, the six items were correlated with other measures, specifically, self-report questionnaires and managers' ratings, of extraversion, proactivity and customer orientation. Correlations were weak, at best (rs ranged from -.06 to .25). To test the predictive validity of the interview, the six items were correlated with both objective and subjective measures of performance. Predictive validities were stronger, ranging from .23 to .30. These findings are consistent with previous research on employment interviews which have found that although the predictive validity of the interview is strong, the construct validity is very weak, leaving researchers to wonder what it is that the interview is actually measuring. Possible explanations for these findings are offered, and the implications of these findings are discussed.

PhD Thesis / Background: Overcrowding in emergency departments (EDs) due to avoidable visits places a significant strain on health systems. There is no known valid classification to identify avoidable ED visits in Canadian administrative data. Research Questions: Which physician interventions and patient characteristics are important to classify avoidable ED visits, and does a novel classification (the Emergency Department Avoidability Classification; EDAC), which incorporated these features, demonstrate validity? Methods: Two independent modified Delphi consensus studies determined ED physician interventions and patient characteristics that classified avoidable ED visits. These studies involved emergency and family medicine physicians across Ontario, Canada. Binary logistic regression was used to examine ED physician interventions in the National Ambulatory Care Reporting System (NACRS) database for associations with patient characteristics. These results constructed the EDAC criteria. ED physicians from an academic hospital evaluated randomly selected retrospective ED visits (n=320) which were also evaluated using the EDAC to assess their avoidability. The primary outcome of this thesis was correlation between the classification and ED physician judgements, measured using a Spearman rank correlation and ordinal logistic regression. The secondary outcome was to compare the correlations of previously published classifications with ED physician judgements. The tertiary outcome was to compare prevalence estimates of avoidable ED visits for all classifications. Results: Consensus showed strong evidence on 146 of 150 (97.3%) ED physician interventions, with 103 (68.7%) deemed suitable for non-ED care. Consensus was established on eight of nine patient characteristics, with four characteristics identified as useful in specifying avoidable ED visits: age (18-70 years), triage acuity (non-emergent), specialist consult in the ED (none) and ED visit outcome (discharged). An adjusted retrospective cohort study found the ED interventions had a strong association with patient characteristics determined in the consensus study: not aged over 65 years, having a non-emergent triage acuity and not being admitted to hospital. The classification was highly correlated with ED physician judgements (r=0.64, p<0.01), with a significant association to classify avoidable ED visits (OR=80.0, 95% CI=17.1-374.9) and strong accuracy (82.8%). The EDAC was the most accurate classifier of avoidable ED visits compared to previously published classifications. The EDAC identified a prevalence of 25.1% ED visits as avoidable and common patient conditions associated with such visits as traumatic injuries, symptoms/signs/abnormal findings, diseases of the musculoskeletal system, mental and behavioural disorders, and diseases of the respiratory system. Conclusion: My thesis developed and established the EDAC as an accurate classifier of avoidable ED visits with supporting evidence of validity and superior performance to previously published classifications. The EDAC can be easily integrated with administrative ED data and has strong potential for use in defining avoidable ED visits by health policy stakeholders. / Thesis / Doctor of Philosophy (PhD)

Theoretical developments of emotional intelligence (EI) are jeopardized by the inability of empirical studies to keep pace with its intense surge to the forefront of both lay and academic communities. Due to the paucity of empirical evidence, claims of the contributions of EI are met with speculation in the scientific community. Furthermore, EI is conceptualized and measured in a variety and often, diverging ways. Subsequent to indications from previous literature that EI shows promise to be linked to the field of health and psychological well-being (Austin, Saklofske, & Egan, 2005), the primary aim of this study was to investigate the concurrent criterion validity of a mixed model conceptualization of EI with self-reported exercise attitudes by comparing two subsamples of university students, (Mean Age = 22 years; 72% Female, 28% Male; NonKinesiology n1 = 271, Kinesiology n2 = 127). The finding of a weak overall correlation fails to provide concurrent criterion validity to the BarOn (2002) conceptualization of EI with exercise attitudes as measured by HBQ (Austin, unpublished), r(398) = .13, p = .013. This finding is further substantiated by the lack of significant findings in an ANOVA and a lack of practical significance in a MANOVA. While the criterion group had significantly stronger beliefs of the benefits of exercise, F(1, 394) = 47.54, p < .001, Å2 = .11; no significant difference between the means of the Composite EI was found between the subsamples for the main effect (field of study) or for the interaction effect (field of study ~ sex): F(1, 394) = 0.08, p = .78; F(1, 394) = 1.82, p = .18, respectively. Additionally, the MANOVA findings determined that only 1.6% of the overall variance could be attributed to the model effect of self-reported activity level and exercise attitude with EI. The secondary purpose of this study was to examine the sex differences in the relationship of EI and exercise attitudes. The scales for the female subsample were not significantly correlated, r(287) = .07, p = .25; whereas, a low and significant correlation was found in the male subsample, r(111) = .37, p = .001. The finding is noteworthy and appears to suggest that the contributing factor to the significant, but weak overall correlation, was obtained from the male sector. Although, the study does find the BarOn EQ-i:S instrument to be a good measure with strong internal consistency reliability and large intercorrelations with its components, the findings point to concerns as to what is being measured and the degree to which the measure overlaps with the personality domain.

Past research indicates that self-compassion has positive implications for psychological health and functioning. However, as a newly specified construct, the literature regarding self-compassion could benefit from a more thorough validation of the primary scale used in this area of research, the Self-Compassion Scale. In the present study, structural path analysis (using Amos) was used to explore the criterion validity of the SCS with four variables which have been theorized to be relevant to self-compassion (caregiver emotional responsiveness, fear of emotion, internalized spirituality, and achievement goal orientation). Initial hypothesis testing indicated support for the path model, with the exception of achievement goals which were not significantly associated with self-compassion. Trimming these paths in a subsequent analysis improved model fit. Interestingly, further analyses of the model indicated that the pairing of participant and parent gender produced substantial differences in path coefficients. Next, correlational and factor analytic methods were used to test the construct validity of the SCS. Correlational analyses found adequate convergent construct validity but some lack of divergent validity between SCS dimensions and conceptually similar constructs (i.e., fear of emotion, social connectedness and self-criticism). Confirmatory factor analysis indicated that a two-factor model fit the data better than the one-factor model proposed by the author of the SCS. The incremental validity of the two-factor model was supported by incorporating a two-factor SCS in the path analysis. In sum, these findings generally support the criterion validity of the SCS through meaningful associations with theoretically relevant variables but cautions that these associations are strongly influenced by gender. It is also strongly recommended that a two-factor model of the SCS be explored in further research to ascertain its incremental utility for understanding self-compassion’s positive effects on psychological health.

Background: Three dimensional motion analysis systems and goniometer measurement are often analyzed in relation to each other in biomechanical science, although the correlation between the methods are not well researched.  Aim and purpose: To investigate the criterion validity between physical examination of lower extremity using a goniometer with a three dimensional motion analysis system. Method: Six healthy participants (12 lower limbs) were recruited. The variables of interest were passive hip internal and external rotation, knee joint extension, static knee valgus, internal and external tibia rotation, bimalleor angle and ankle dorsal flexion range of motion. Measurements were collected with goniometer and a three dimensional motion analysis system. A modified Helen Hayes marker set was used and the physical examination was made by two physiotherapists using conventional testing positions. Spearman’s rank correlation coefficient and Bland Altman plot were used to describe correlation and level of agreement, respectively. Results: Hip external rotation (rs=0.97), BMA (rs=0.96) and hip internal rotation (rs=0.89) showed acceptable and significant correlation (p&lt;0.01). Tibia internal rotation (0.60, significant p&lt;0.05), ankle dorsiflexion (rs=0.56 p&gt;0.05) tibia external rotation (rs=0.50 p&gt;0.05) knee valgus (rs=-0.16 p&gt;0.05), knee extension (rs=-0.20 p&gt;0.05) did not correlate. Conclusion: The criterion validity were good between the measurements for hip external and internal rotation and BMA. Criterion validity could not be described for the other measurements.

Yes / In this study we examine the structures of ten personality inventories widely used for personnel assessment, by mapping the scales of personality inventories (PIs) to the lexical Big Five circumplex model resulting in a ‘Periodic Table of Personality’. Correlations between 273 scales from ten internationally popular PIs with independent markers of the lexical Big Five are reported, based on data from samples in two countries (UK N = 286; USA N = 1,046), permitting us to map these scales onto the AB5C framework. Emerging from our findings we propose a common facet framework derived from the scales of the PIs in our study. These results provide important insights into the literature on criterion-related validity of personality traits, and enable researchers and practitioners to understand how different PI scales converge and diverge and how compound PI scales may be constructed or replicated. Implications for research and practice are considered.
