BackgroundThere has been limited research on the positive aspects of physician wellness and to our knowledge there have been no validity studies on measures of resilience and grit among internal medicine (IM) residents.ObjectivesTo investigate the validity of resilience (10 items Connor-Davidson Resilience Scale (CD-RISC 10)) and grit (Short Grit Scale (GRIT-S)) scores among IM residents at a large academic centre, and assess potential associations with previously validated measures of medical knowledge, clinical performance and professionalism.MethodsWe evaluated CD-RISC 10 and GRIT-S instrument scores among IM residents at the Mayo Clinic Rochester, Minnesota between July 2017 and June 2019. We analysed dimensionality, internal consistency reliability and criterion validity in terms of relationships between resilience and grit, with standardised measures of residents’ medical knowledge (in-training examination (ITE)), clinical performance (faculty and peer evaluations and Mini-Clinical Evaluation Examination (mini-CEX)) and professionalism/dutifulness (conference attendance and evaluation completion).ResultsA total of 213 out of 253 (84.2%) survey-eligible IM residents provided both CD-RISC 10 and GRIT-S survey responses. Internal consistency reliability (Cronbach alpha) was excellent for CD-RISC 10 (0.93) and GRIT-S (0.82) overall, and for the GRIT subscales of consistency of interest (0.84) and perseverance of effort (0.71). CD-RISC 10 scores were negatively associated with ITE percentile (β=−3.4, 95% CI −6.2 to −0.5, p=0.02) and mini-CEX (β=−0.2, 95% CI −0.5 to −0.02, p=0.03). GRIT-S scores were positively associated with evaluation completion percentage (β=2.51, 95% CI 0.35 to 4.67, p=0.02) and conference attendance (β=2.70, 95% CI 0.11 to 5.29, p=0.04).ConclusionsThis study revealed favourable validity evidence for CD-RISC 10 and GRIT-S among IM residents. Residents demonstrated resilience within a competitive training environment despite less favourable test performance and grittiness that was manifested by completing tasks. This initial validity study provides a foundation for further research on resilience and grit among physicians in training.

Microaggressions are daily insults to minority individuals such as people with disabilities (PWD) that communicate messages of exclusion, inferiority, and abnormality. In this study, we developed a new scale, the Ableist Microaggressions Impact Questionnaire (AMIQ), which assesses ableist microaggression experiences of PWD. Data from 245 PWD were collected using Amazon’s Mechanical Turk (MTurk) platform. An exploratory factor analysis of the 25-item AMIQ revealed a three-factor structure with internal consistency reliability ranging between .87 and .92. As a more economical and psychometrically sound instrument assessing microaggression impact as it pertains to disability, the AMIQ offers promise for rehabilitation counselor research and practice.

Abstract Background Torture methods have traditionally been quantified using checklists. However, checklists fail to capture accurately both the almost infinite range of available methods of torture and the victims’ subjective experience. The Torturing Environment Scale (TES) was designed as a multidimensional alternative that groups torture methods according to the specific human function under attack. This study aims to do an exploratory assessment of the internal consistency reliability and discriminatory validity of the TES as part of a construct validity assessment in a sample of Basque torture survivors. Methods We applied the TES to a sample of 201 torture survivors from the Istanbul Protocol Project in the Basque Country Study (IPP-BC) to profile torturing environments in detention. To estimate the internal consistency reliability of the scale, categorical omega values were obtained for each subscale of the TES. To assess its discriminatory validity, the “known groups” method was used comparing mean scorings by gender, state security forces involved in the detention, and decade (the 1980s to the present) when the events took place. Results Men reported more physical pain, while women reported more attacks on self-identity and sexual integrity. The TES also showed significant differences as regards the security forces involved in the detention: Civil Guard (a militarised police) used more manipulation of the environment, threats, fear, pain and extreme pain, as compared to national and regional corps. Finally, although patterns of torture remained mostly unchanged across decades, more recent detentions included more emphasis on psychological attacks: context manipulation, humiliation linked to sexual identity, and attacks to meaning and identity. For all subscales of the TES, categorical omega values ranged from 0.44 to 0.72. Conclusion The TES may be a useful tool in profiling torturing environments. Its sensitivity to key contextual variables supports the discriminatory validity of the scale. While some of the subscales showed an acceptable degree of internal consistency, others require further analysis to improve reliability. The scale provides unique insights into the profile of contemporary torture. It will allow for future quantitative research on the relationship between different torturing environments and the medical and psychological consequences thereof.

BackgroundFeline osteoarthritis (OA) is a common cause of long-standing pain and physical dysfunction. Performing a physical examination of a cat is often challenging. There is a need for disease-specific questionnaires or the so-called clinical metrology instruments (CMIs) to facilitate diagnosis and evaluation of treatment of feline OA. The CMI provides the owners an assessment of the cat’s behavioural and lifestyle changes in the home environment. The purpose of the study was to evaluate readability, internal consistency, reliability and discriminatory ability of four CMIs.MethodsThis is a prospective, cross-sectional study with 142 client-owned cats. Feline OA was diagnosed based on medical history, orthopaedic examination and radiography.ResultsThe results indicate that all four instruments have sound readability, internal consistency, are reliable over time and have good discriminatory ability. Preliminary cut-off values with optimal sensitivity and specificity were suggested for each instrument. The osteoarthritic cats showed significant changes in behavioural response to pain during orthopaedic examination, compared with sound cats.ConclusionThe results indicate that all four questionnaires make an important contribution in a clinical setting, and that the cat’s behavioural response to pain during physical examination should be a parameter to take into account as a possible indication of chronic pain.

This study refined the Support Needs Inventory for Parents of Asthmatic Children (SNIPAC) (Coleman, Maltby, Kristjanson, & Robinson, 2001) to produce a more parsimonious tool to assess the importance and meet the support needs of parents of children with asthma. The original tool was completed by 145 parents of 199 children with asthma, and 74 of these also provided test-retest responses. Internal consistency reliability, construct validity, and stability over time were assessed and refinements were made. Internal consistency reliability of the revised 20-item tool ranged from .77 to .95 for the three subscales of the Parent’s Priority Scale (PPS), and .92 for the full PPS. Cronbach’s alphas ranged from .74 to .90 for the three subscales of the Parent’s Fulfillment Scale (PFS) and was .91 for the full scale. Factor analysis results of the PPS were compatible with the tool’s conceptual framework. The revised 20-item tool demonstrated adequate psychometric properties in most areas. This tool may be used for research or clinical screening without imposing undue burden on parents. Further work is required to establish the tool’s stability over time.

Background There is heterogeneity in conceptualizations of resiliency, and there is, to date, no established theoretically driven resiliency assessment measure that aligns with a targeted resiliency intervention. We operationalize resiliency as one’s ability to maintain adaptive functioning in response to the ongoing, chronic stress of daily living, and we use a novel resiliency measure that assesses the target components of an evidence based resiliency intervention. We present our resiliency theory, treatment model, and corresponding assessment measure (Current Experience Scale; CES). Methods To establish the psychometric properties of the CES, we report the factor structure and internal consistency reliability (N = 273). Among participants in our resiliency intervention (N = 151), we explored construct validity in terms of associations with theoretical model constructs, a validated resiliency measure, and sensitivity to change from before to after the intervention. Results Results indicated that a 23-item, 6-factor solution was a good fit to the data (RMSEA = .08, CFI = .97; TLI =.96) and internal consistency was good (α = .81 to .95). The CES showed correlations in the expected direction with resiliency model constructs (all p’s < .001) and significant post intervention improvements. Conclusion Our resiliency theory, treatment model, and outcome appear aligned; the CES demonstrated promise as a psychometrically sound outcome measure for our resiliency intervention and may be used in future longitudinal studies and resiliency building interventions to assess individuals’ resiliency to adapt to ongoing stress.

Background: Each year, nearly 800,000 people experience a new or recurrent stroke. To assess changes in neurological status during hospitalization, nurses are required to complete the 15-item National Institute of Health Stroke Scale (NIHSS), which is time consuming and therefore, may not be completed as thoroughly as it should. To ensure these patients are being effectively and adequately assessed, there is a need for an abbreviated NIHSS, which can be completed in a shorter time frame. Purpose: The purpose of this study was to determine the merits of an abbreviated NIHSS using seven items considered to be key to determining changes in neurological status. Methods: Over a six month period, 100 scores from the 15-item NIHSS were collected on a sample of 92 acute care stroke patients who had a mean age of 64.2; 52% were female. Seven items were calculated, which included level of consciousness, left and right arm motor movement, left and right leg motor movement, speech fluency, and speech clarity. To assess internal consistency reliability of the 7-item NIHSS, Cronbach's α was computed. To assess criterion validity, the 7-item NIHSS and 15-item NIHSS were correlated using Pearson's r . Results: The 15-item NIHSS ranged from 1 to 37, with a mean of 8.6. The 7-item NIHSS ranged from 0 to 24, with a mean of 4.9. For the 7-item NIHSS, Cronbach's α was .82 and Pearson's r was .96 (p<.001), when correlated with the 15-item NIHSS. Conclusions: Assessment of the acute stroke patient using the 15-item NIHSS is time-consuming, and therefore, may be underutilized. An abbreviated 7-item NIHSS demonstrated satisfactory evidence of internal consistency reliability and criterion validity, when correlated with the 15-item NIHSS, suggesting the 7-item version may be a suitable alternative to the longer version. More psychometric testing is warranted to fully evaluate reliability and validity of the 7-item NIHSS.
