Evidence Of Discriminant Validity Research Articles

Discriminant validity evidence for the multilingual Life Satisfaction Scale for Apostolic Women Religious (LSSAWR)

ABSTRACT Worldwide intergovernmental organizations are encouraging nations to use well-being and economic measures when making policy decisions. The Life Satisfaction Scale for Apostolic Women Religious (LSSAWR) has provided Catholic Sisters the opportunity to explore their well-being and mission worldwide. However, there is a continuing need for research to support the use and the interpretations of scores resulting from LSSAWR administration. Thus, this study provided discriminant validity evidence for LSSAWR ratings by comparing its scores with self-reported ratings on overall health screening questions as measured by the Health Screening Questionnaire.

EGame-flow: psychometric properties of the scale in the Mexican context

PurposeThe present study examined the psychometric properties of the EGame- flow scale in a Mexican sample, presenting evidence of construct validity (exploratory factor analysis and confirmatory factor analysis), reliability (Cronbach’s alpha and McDonald’s omega) and discriminant validity (mean variance extracted).Design/methodology/approachParticipants: Of the 255 Mexican participants in the non-probabilistic sample who had previously interacted with the LOST logistics simulator, 166 (65%) were men and 89 (35%) were women; their ages ranged from 22 to 45. The statistical packages SPSS 25, JASP 0.16 and AMOS 23 facilitated the corresponding analyses. First, we calculated the means and standard deviations of the scale items. Next, we performed an exploratory factor analysis to examine the measurement model’s internal structure and a confirmatory factor analysis to confirm the structure proposed in the exploratory factor analysis. To analyze the internal structure of the measurement model so that the estimates were not affected by multivariate normality problems, we utilized the AMOS bootstrap method (with 500 repetitions, 95% CI), the maximum likelihood (MV) estimation method, and the fit indices: X2, p (chi-square and associated likelihood), Tucker–Lewis index (TLI), standardized statistical mean square residual (SRMR), comparative fit index (CFI) and root mean Square error approximation (RMSEA) with its confidence interval, the values of X2 with p < 0.001; TLI, CFI, AGFI = 0.95; RMSEA and SRMR = 0.08 (Byrne, 2016). Finally, we estimated the reliability of the measurement model with Cronbach’s alpha (a), McDonald’s omega (ω) coefficient and the mean variance extracted (VME).FindingsAn exploratory factor analysis with the MV method and obliminal rotation showed a good fit of the data to the model, which aligns with the significance of the Barlette sphericity test (X2 = 8443.2, p < 0.000) and the Kaiser–Meyer-Olkin (KMO) value of 0.94. The indices confirmed the fit of the data to the six-dimensional model for measuring the users' level of enjoyment of online games (X2 = 678.2 gl = 411, p = 0.000; SRMR = 0.05; TLI = 0.95, CFI = 0.95 and RMSEA = 0.05, IC 90% [0.04, 0.05]).Research limitations/implicationsThe self-reporting format of the scale increases the social desirability of the responses, but the sample only collects information from a specific geographic location, so these findings cannot extrapolate to populations with very marked cultural differences. Finally, the study did not measure other validity evidence, such as predictive and concurrent validity, which should be considered in future studies.Practical implicationsFrom a practical perspective, the study offers a measurement scale with fewer items and robust psychometric evidence that ensures the fit of the data to the EGame-flow measurement scale. Further research must continue to learn about the behavior of the EGame-flow scale in different samples that new evidence of psychometric properties continues to appear and that other factors associated with the users' gaming enjoyment experience are analyzed.Originality/valueThe value and originality of the study lie in the type of evidence of psychometric properties that the instrument has and particularly in the style of sample in which the study is carried out, in this case, in the context of Mexico, where there are not enough instruments that measure the flow experience of users.

Spanish and Catalan Versions of the eHealth Literacy Questionnaire: Translation, Cross-Cultural Adaptation, and Validation Study.

The rise of digital health services, especially following the outbreak of COVID-19, has led to a need for health literacy policies that respond to people's needs.Spain is a country with a highly developed digital health infrastructure, but there are currently no tools available to measure digital health literacy fully. A well-thought-through questionnaire with strong psychometric properties such as the eHealth Literacy Questionnaire (eHLQ) is important to assess people's eHealth literacy levels, especially in the context of a fast-growing field such as digital health. This study aims to adapt the eHLQ and gather evidence of its psychometric quality in 2 of Spain's official languages: Spanish and Catalan. A systematic cultural adaptation process was followed. Data from Spanish-speaking (n=400) and Catalan-speaking (n=400) people were collected. Confirmatory factor analysis was used to confirm the previously established factor structure. For reliability, the Cronbach α and categorical ω were obtained for every subscale. Evidence of convergent and discriminant validity was provided through the correlation with the total score of the eHealth Literacy Scale. Evidence based on relations to other variables was evaluated by examining extreme values for educational level, socioeconomic level, and use of technology variables. Regarding the confirmatory factor analysis, the 7-factor correlated model and the 7 one-factor models had adequate goodness-of-fit indexes for both Spanish and Catalan. Moreover, measurement invariance was established between the Spanish and Catalan versions. Reliability estimates were considered adequate as all the scales in both versions had values of >0.80. For convergent and discriminant validity evidence, the eHealth Literacy Scale showed moderate correlation with eHLQ scales in both versions (Spanish: range 0.57-0.76 and P<.001; Catalan: range 0.41-0.64 and P<.001). According to the relationship with external variables, all the eHLQ scales in both languages could discriminate between the maximum and minimum categories in level of education, socioeconomic level, and level of technology use. The Spanish and Catalan versions of the eHLQ appear to be psychometrically sound questionnaires for assessing digital health literacy. They could both be useful tools in Spain and Catalonia for researchers, policy makers, and health service managers to explore people's needs, skills, and competencies and provide interesting insights into their interactions and engagement regarding their own experiences with digital health services, especially in the context of digital health growth in Spain.

Properties of the modified self-forgiveness dual-process scale in populations at risk for moral injury.

Despite theory suggesting that self-forgiveness facilitates recovery from moral injury, no measure of self-forgiveness has been validated with individuals exposed to potentially morally injurious events (PMIEs). Military veterans, healthcare workers, and first responders who reported PMIE exposure (n=924) completed the Self-Forgiveness Dual-Process Scale, which assesses two dimensions of the self-forgiveness process. The first dimension, value affirmation, refers to appraising personal responsibility and being willing to make amends for one's involvement in a PMIE. The second dimension, esteem restoration, refers to accepting oneself as valuable and capable of growth despite one's failures and imperfections. Exploratory and Confirmatory Factor Analyses replicated the original scale's two-factor structure in 10 items modified to apply to the diverse contexts in which PMIEs occur. Next, we found that the factor structure, item loadings, and item intercepts were fully or partially invariant across professions, genders, races, ages, and religious affiliations in a series of Multi-Group Confirmatory Factor Analyses. Finally, diverging patterns of associations between value affirmation and esteem restoration with moral distress, posttraumatic stress, depression, insomnia, functional impairment, and posttraumatic growth provide evidence of convergent and discriminant validity between the subscales. The modified self-forgiveness dual process scale is the first measure of self-forgiveness to be validated with individuals exposed to a PMIE. Researchers and clinicians can use the scale to examine how self-forgiveness (or difficulties with forgiving oneself) relates to moral injury.

The Basic Needs in Games Scale (BANGS): A new tool for investigating positive and negative video game experiences

Players’ basic psychological needs for autonomy, competence, and relatedness are among the most commonly used constructs used in research on what makes video games so engaging, and how they might support or undermine user wellbeing. However, existing measures of basic psychological needs in games have important limitations—they either do not measure need frustration, or measure it in a way that may not be appropriate for the video games domain, they struggle to capture feelings of relatedness in both single- and multiplayer contexts, and they often lack validity evidence for certain contexts (e.g., playtesting vs experience with games as a whole). In this paper, we report on the design and validation of a new measure, the Basic Needs in Games Scale (BANGS), whose 6 subscales cover satisfaction and frustration of each basic psychological need in gaming contexts. The scale was validated and evaluated over five studies with a total of 1246 unique participants. Results supported the theorized structure of the scale and provided evidence for discriminant, convergent and criterion validity. Results also show that the scale performs well over different contexts (including evaluating experiences in a single game session or across various sessions) and over time, supporting measurement invariance. Further improvements to the scale are warranted, as results indicated lower reliability in the autonomy frustration subscale, and a surprising non-significant correlation between relatedness satisfaction and frustration. Despite these minor limitations, BANGS is a reliable and theoretically sound tool for researchers to measure basic needs satisfaction and frustration with a degree of domain validity not previously available.

Spanish Adaptation of the Mentalization Questionnaire (MZQ) in Community Adolescents and Adults.

Despite the role of mentalization in mental health outcomes and prevention, psychometrically-evaluated screening measures for mentalization remain sparse. One widely-used mentalization questionnaire is the Mentalization Questionnaire (MZQ; Hausberg et al., 2012), which we aimed to adapt and validate for use in Spanish. We adapted the MZQ to European Spanish and evaluated its psychometric properties in both adolescent (n = 389, ages 12-19, M = 14.5) and adult community samples (n = 382, M = 48). Confirmatory factor analysis resulted in a unidimensional structure including all items. This model had better goodness of fit than the original and other adaptations. Invariance analysis showed the same structure in adolescents compared by sex and age, and additionally in the adult versus adolescent samples. Evidence for convergent and discriminant validity was found. Internal consistency values in both adolescents and parents were fair and in the adolescent sample the MZQ scores remained moderately stable after re-test. The Spanish adaptation of the MZQ presents similar evidence of reliability and validity in the adolescent and adult samples. The results support this being a suitable version for evaluating mentalization in the general population.

Psychometric testing of the Chinese version of the Perceived Maternal Parenting Self-Efficacy Scale among postpartum women.

Maternal parenting self-efficacy plays a critical role in facilitating positive parenting practices and successful adaption to motherhood. The Perceived Maternal Parenting Self-Efficacy Scale (PMPS-E), as a task-specific measure, confirms its psychometric properties in cultural contexts. Compared with other tools, the advantages of the PMPS-E are as follows: (i) specific context or time period during the lifespan of a child, (ii) explicitly assess parenting self-efficacy across a diverse enough range of parenting tasks or activities during the perinatal/postnatal period and (iii) having robust psychometric properties. The aim of this study was to translate and determine the psychometric properties of the PMPS-E among Chinese postpartum women (C-PMPS-E). The cross-cultural adaptation process followed Beaton et al.'s intercultural debugging guidelines. A total of 471 women were included to establish the psychometric properties of the C-PMPS-E. Mothers were asked to complete the C-PMPS-E, Edinburgh Postnatal Depression Scale (EPDS), the Generalized Anxiety Disorder-7 (GAD-7) and several demographic questions. The psychometric testing of the C-PMPS-E was established through item analysis, construct validity and internal consistency reliability. Item analysis showed that the critical ratios of all items were greater than 3 between the low-score group and high-score group, and all item-total correlation coefficients were greater than 0.4. The fit indices showed that the original correlated four-factor model of C-PMPS-E was observed to be an excellent fit to the data. The PMPS-E was negatively correlated with the EPDS and GAD-7 demonstrating its discriminant validity. As expected, no significant correlation was found between PMPS-E total or subscale scores and mothers' age. In addition, statistically significant differences for parity were detected for C-PMPS-E total and subscale scores with multipara having higher scores. This was taken as further evidence of the scale known-groups discriminant validity. In terms of internal consistency, the Cronbach's alpha of the C-PMPS-E total scale was 0.950, and subscales ranged from 0.76 to 0.89. Furthermore, a ROC curve analysis was conducted to establish the ability of the C-PMPS-E to distinguish between symptoms of depression and symptoms of anxiety. A cut-off value of 55 was identified that resulted in good specificity and fair sensitivity. The C-PMPS-E is a reliable and valid tool to assess maternal parenting self-efficacy in a Chinese context.

Construction and Validation of the Belief in Divine Retribution Scale for Pakistani Muslims.

The purpose of the study was to construct and validate a Belief in Divine Retribution Scale for the Pakistani Muslim population. The process of construction and validation was completed by following standardized guidelines for scale construction (Boateng et al., 2018). The present study was carried out in four phases. In phase I, the task of item generation was completed through literature review and interviews (inductive and deductive approaches). Phase II aimed at exploration of factor structure. Exploratory factor analysis was carried out on a sample of seven hundred Muslim participants. Data for EFA were collected through a purposive sampling technique, which comprised both men (n = 339) and women (n = 361) with an age range of 18 to 69years. Results of EFA revealed a two-factor structure with a cumulative variance of 42.59 and with a Cronbach alpha reliability of .83. To confirm the obtained factor structure, Phase III was carried out on a sample of three hundred Muslim participants. The results of CFA confirmed the two-dimensional factor structure with a good model fit to the data. Phase IV provided evidence of convergent and discriminant validity of the scale. Moreover, data for validation were collected from an independent sample (N = 204). Finally, the results of validation revealed that there exists a significant positive correlation of Belief in Divine Retribution Scale with Belief in Just World Scale, which provided evidence of convergent validity. However, there exists a non-significant correlation of Belief in Divine Retribution Scale with Religious Practice Subscale of Short Muslim Practice and Belief Scale, and it provided evidence of discriminant validity. Implications along with limitations and suggestions for future research have also been mentioned.

Spanish Adaptation of the Social Worries Questionnaire (SWQ): A Tool to Assess Social Anxiety in Preadolescent Children

AbstractSocial anxiety may appear during preadolescence, causing children to worry and avoid situations where they may be evaluated by others. Previous studies have shown that about 4% of preadolescents present clinically elevated levels of social anxiety, which is related to the later onset of other problems. Therefore, it becomes necessary to have available screening measures, with few items, that assess the different social situations that elicit anxiety, as is the case of the Social Worries Questionnaire (SWQ). The objective of this study was to adapt and assess the psychometric properties of the SWQ in Spanish preadolescent children. The sample was composed of 218 children aged 8 to 12 years (54.1% boys). The SWQ, along with other measures of depression, anxiety and self-concept, were online administered to children. An item addressing videoconference anxiety was added to the SWQ. Using Confirmatory Factor Analysis, a one-factor structure composed of 14 items demonstrated favorable fit indices. The results indicate evidence of concurrent and discriminant validity, good internal consistency (Cronbach’s α = 0.81; ordinal α = 0.87) and moderate-to-good test-retest stability. Despite some limitations, the Spanish adaptation of the SWQ shows good psychometric properties and enables the assessment of social anxiety generalization to several situations. The questionnaire can be a valuable self-reported tool for detecting risk cases and guiding the treatment in clinical settings.

The development and validation of a Multidimensional Perceived Work Ability Scale.

Research on the concept of existing unidimensional Perceived Work Ability scale (PWA) in organizational science has recently increased due to its prediction of important work, individual, and labor force outcomes. To date, PWA has been measured as a unidimensional construct. The present study outlines the need for the multidimensional conceptualization of PWA and its measurement. We describe the development and validation of the Multidimensional Perceived Work Ability Scale (M-PWAS), comprising four dimensions: physical, cognitive, interpersonal, and emotional. In line with Hinkin's (1998) approach to scale validation, we use four samples (total N = 1,152) to establish the M-PWAS as a reliable and valid measure of PWA. Through an iterative item generation and review process, we found evidence for content validity. Furthermore, each subscale demonstrated high internal consistency and factorial validity, and analysis of the PWA nomological network demonstrated evidence for convergent and discriminant validity. Finally, we found that the M-PWAS showed incremental validity over an existing unidimensional PWA measure in the prediction of perceived stress, emotional exhaustion, work engagement, and turnover. We discuss implications for theory, research, and workplace interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Compromiso organizacional y bienestar en el trabajo: investigando modelos alternativos de asociación

This study aimed to verify the association between well-being at work (WBW) and organizational commitment (COMM) and to determine whether they behave as equivalent phenomena, correlated phenomena, or whether well-being is an antecedent or a consequence of commitment. This is a quantitative, cross-sectional study, with a survey applied to 360 workers from various organizations. Correlation analyses, linear regression, and structural equation modeling were used. Evidence of discriminant validity was found between COMM and WBW. There is evidence for the hypothesis that the association between WBW and COMM is cyclical, based on feedback, which is a possible explanation for the contradiction found in the literature regarding the pattern of association between these phenomena. The association between these two phenomena could be seen as a process, a flow, whose complexity may be more difficult for cross-sectional research to grasp.

Anosognosia in Alzheimer's Pathology: Validation of a New Measure.

Two studies were performed to validate a brief measure of cognitive insight and compare it to an empirical model - the Cognitive Awareness Model (CAM). A pilot study included 31 (52% male; Mage = 69.42) patients from an outpatient neuropsychological assessment clinic. Seven patients were diagnosed with likely Alzheimer's dementia (AD), 15 mild cognitive impairment (MCI), and 9 no diagnosis (i.e., cognitively normal; CN). The Cognitive Coding Form (CCF) and several other measures were administered. Study 2 entailed archival data extraction of 240 patients (80 CN, 80 MCI, and 80 AD; 53.3% female; Mage = 72.8) to examine whether the CCF predicts memory (Wechsler Memory Scale - IV) and executive functioning (Trail-Making Test B). The pilot study found preliminary evidence of convergent and discriminant validity for the 8-item CCF. Study 2 confirmed that both patient-reported cognitive concerns (F(2,237) = 10.40, p < .001, ω2 = .07, power = .99) and, more strongly, CCF informant-patient discrepancy scores (F(2,237) = 24.52, p < .001, ω2 = .16, power = .99) can distinguish CNs from those with MCI and AD. A regression indicated that depression (5.5%; β = -.38, p < .001) and TMT-B (13%; β = -.43, p < .001), together accounted for 18.5% of the variance in insight (R2 = .19, F(2,219) = 26.10, p < .001), supporting the CAM. These studies establish an efficient measure of insight with high clinical utility and inform the literature on the role of insight in predicting performance in those with Alzheimer's pathology.

Development of the Earthquake Anxiety Scale: Validity and Reliability Study

In this study, it was aimed to develop a new, valid and reliable measurement tool to measure general earthquake anxiety (EAS). For this purpose, firstly, the literature on earthquake was reviewed and an item pool was created. Then, two separate samples were taken for EFA and CFA. In order to determine the factor structure of the measurement tool, EFA was applied on the data obtained from the first sample group and a structure with 2 factors and 13 items was reached. In order to test the accuracy of this structure, data were collected from a different sample group and CFA was applied on these data. The results revealed that the scale has evidence of construct validity, discriminant validity and internal consistency reliability. In addition, earthquake anxiety scale items can be used to assess anxiety levels in different age groups.

Perceptions of Justice in Clinical Learning Environments: Development and Validation of an Organizational Justice Measure for Medical Trainees.

This study aimed to develop an instrument to measure medical trainees' perceptions of justice in clinical learning environments. Between 2019 and 2023, the authors conducted a multiyear, multi-institutional, multiphase study to develop a 16-item justice measure with 4 dimensions: interpersonal, informational, procedural, and distributive. The authors gathered validity evidence based on test content, internal structure, and relationships with other variables across 3 phases. Phase 1 involved drafting items and gathering evidence that items measured intended dimensions. Phase 2 involved analyzing relevance of items for target groups, examining interitem correlations and factor loadings in a preliminary analysis, and obtaining reliability estimates. Phase 3 involved a confirmatory factor analysis and collecting convergent and discriminant validity evidence. In phase 1, 63 of 91 draft items were retained following a content validation exercise gauging how well items measured targeted dimensions (mean [SD] item ratings within dimensions, 4.16 [0.36] to 4.39 [0.34]) on a 5-point Likert scale (with 1 indicating not at all well and 5 indicating extremely well). In phase 2, 30 items were removed due to low factor loadings (i.e., < 0.40), and 4 items per dimension were selected (factor loadings, 0.42-0.89). In phase 3, a confirmatory factor analysis supported the 4-dimension model (χ2 = 610.14, P < .001; comparative fit index = 0.90, Tucker-Lewis Index = 0.87, root mean squared error of approximation = 0.11, standardized root mean squared residual = 0.06), with convergent and discriminant validity evidence showing hypothesized positive correlations with a justice measure (r = 0.93, P < .001), trait positive affect (r = 0.46, P < .001), and emotional stability (r = 0.33, P < .001) and negative correlations with trait negative affect (r = -0.39, P < .001). Results indicate the measure's potential utility in understanding justice perceptions and designing targeted interventions.

Further development of the reflective practice questionnaire.

This article provides an update of the Reflective Practice Questionnaire (RPQ). The original RPQ consisted of 40-items with 10-sub-scales. In this article, the RPQ is streamlined into a 10-item single reflective practice construct, and a 30-item extended version that includes additional sub-scales of confidence, uncertainty/stress, and work satisfaction. A total of 501 university students filled out an online questionnaire that contained the original Reflective Practice Questionnaire, and two general measures of reflection: The Self-Reflection and Insight Scale, and the Rumination-Reflection Questionnaire. Based on factor analysis, the RPQ was streamlined into a brief 10-item version, and an extended 30-item version. Small positive correlations were found between the RPQ reflective practice measure and the two measures of general reflection, providing discriminant validity evidence for the RPQ. The RPQ was found to be sensitive to differences among industries, whereas the general measures of reflection were not. Average reflective practice scores were higher for health and education industries compared to retail and food/accommodation industries.

Examining the validity of the addictions neuroclinical assessment domains in a crowdsourced sample of adults with current alcohol use.

Several dimensional frameworks for characterizing heterogeneity in alcohol use disorder (AUD) have been proposed, including the Addictions Neuroclinical Assessment (ANA). The ANA is a framework for assessing individual variability within AUD across three domains corresponding to the proposed stages of the addiction cycle: reward (binge-intoxication stage), negative emotionality (withdrawal-negative affect stage), and cognitive control (preoccupation-anticipation stage). Recent work has evaluated the ANA's three-factor structure and construct validity, primarily in treatment-seekers with AUD. We extended this research by examining the factor structure, bias across alcohol use severity, longitudinal invariance, and concurrent and predictive validity of a novel assessment of the ANA domains in adults with past 12-month regular (10 + alcohol units/week) alcohol use. Participants recruited from Prolific (N = 732), a crowdsourced data collection platform, completed various self-report measures. A test-retest subsample (n = 234) completed these measures 30 days later. Split-half exploratory factor analysis and confirmatory factor analysis supported the three-factor structure of the ANA. The overall factor structure was invariant across 30 days. Concurrently and prospectively, ANA domains demonstrated convergent validity concerning theoretically aligned alcohol-related, psychological, and personality measures. However, there was evidence of poor discriminant validity, and several cognitive control and reward items demonstrated bias across alcohol use severity. Future research is needed to improve the measurement of ANA domains using multimodal indicators, examine longitudinal changes in domains and their relationship with alcohol use severity, characterize phenotypic subgroups based on relative levels of domains, and compare the utility of the ANA with other proposed frameworks for measuring AUD heterogeneity.

When organizational dehumanization hits home: Short‐scale validation and test of a spillover–crossover model

AbstractOrganizational dehumanization, a concept that has garnered increasing scholarly attention, still faces two significant limitations within the current literature. First, there is a lack of rigorously validated scales in the field. Second, the effects of organizational dehumanization on the family domain have been largely overlooked. In light of these gaps, we embarked on a comprehensive research project comprising five studies (NTotal = 2635) to address these limitations. Our primary objectives were twofold: (1) to develop and validate a concise five‐item scale for measuring organizational dehumanization based on Caesens et al.'s (Eur. J. Work Org. Psychol., 26, 2017, 527‐540) 11‐item measure (Studies 1, 2 and 3) and (2) to investigate a novel spillover–crossover model of organizational dehumanization (Studies 4 and 5). Our results indicated that our proposed short scale has a good factorial structure and high reliability indices, correlates strongly with the 11‐item full scale, is invariant over time and demonstrates evidence for convergent, discriminant and incremental validity. In addition, using data from both employees and their family members, we showed that organizational dehumanization contributes to an increase in work‐to‐family conflict among employees, as perceived by their family members. This, in turn, heightens relationship tension within their family members, ultimately leading to a decline in their relationship satisfaction. Theoretical and practical implications and avenues for future research are also discussed.

Examination of Construct Validity of ANX and DEP Scales of the PAI-A

Anxiety and depression are the two most common psychiatric problems of adolescence. The Personality Assessment Inventory, Adolescent Version (PAI-A) is a broadband instrument designed to assist in the detection and differential diagnosis of common psychiatric disorders in adolescents, and it includes a Depression scale (DEP) to detect the presence of major depressive episodes and an Anxiety scale (ANX) designed to detect clinically significant anxiety. However, there is limited research on this measure. The current study examined both the convergent and discriminant validities of the PAI-A Anxiety and Depression scales by observing their relationships to other self-report measures (e.g., PAI-A scales, MMPI-A), observer ratings (e.g., HPRS), and performance-based measures (e.g., Rorschach CS). The sample consisted of 352 records of the psychological assessments of adolescent inpatients between the ages of 13 to 17; the sample was about equally male (51.6%) and female with a mean age of 15.5 years. The sample was ethnically diverse with 48.7% of individuals identifying as Caucasian, 12.9% Black, 16% Hispanic, 2.6% Asian, 3.2% Other, and 16.6% unknown. There is strong evidence for convergent validity for the PAI–A ANX and DEP scales with r’s ranging from .11 to .78. There is moderate evidence for discriminant validity for these scales. Results demonstrated that PAI–A scales correlated strongest with self-report, followed by therapist rating scale, and then performance-based measures. Various strengths of the PAI-A for the assessment of anxiety and depression are discussed.

Validating a fear-of-falling-related activity avoidance scale in lower limb prosthesis users.

Limited available data suggest that fear of falling (FoF) may be common among lower limb prosthesis users (LLPUs) and associated with negative rehabilitation outcomes. The impact of FoF on outcomes may be exacerbated when fear leads to self-imposed declines in activity. There is a need to identify the validity of fear-of-falling-related activity avoidance scales in LLPUs. To evaluate the convergent, discriminant, and known-group construct validity of the modified Survey of Activities and FoF in the Elderly (mSAFE) for LLPUs. Secondarily, we sought to determine if the mSAFE scale could be reduced without losing information regarding construct validity. Online survey. Not applicable. Fifty-nine persons with unilateral or bilateral amputation at the transtibial or transfemoral level, with ≥6 months experience using a definitive prosthesis for activities other than transfers. Participants completed an online survey that consisted of the mSAFE and questions to assess FoF (yes/no), fear-of-falling-related activity avoidance (yes/no), as well as previously validated scales capturing related and unrelated constructs. T-tests were used to compare mSAFE score between yes/no respondents for known-group construct validity. Correlations between mSAFE and previously validated surveys assessed convergent and discriminant validity. Analyses were repeated on a reduced number of mSAFE items following a redundancy analysis. Not applicable. Significant correlation coefficients of |0.440-0.825| were found for convergent validity with evidence of known-group construct validity (p < .021 for all comparisons). There was evidence for discriminant validity, with non-significant associations for two-of-three correlations. Results from validity analyses for a shortened 6-item mSAFE were similar to that for the full scale. This study provided initial evidence regarding validity of the mSAFE as a measure to assess fear-of-falling-related activity avoidance in LLPUs. A 6-item scale may be appropriate if the full scale would be taxing or time-consuming.

Psychometric Properties of the Wake Forest Physician Trust Scale with Older Adults

Background: Trust is an integral part of the patient–physician relationship. None of the current measures of patient–physician trust has been validated with a sample of older adults. Age-appropriate samples are needed to support the use of assessment instruments and accurate interpretation of assessment results. The purpose of the study was to examine the psychometric properties of the Wake Forest Physician Trust Scale (WFPTS) with a sample of older adults. Methods: Internal consistency and convergent and discriminant validity evidence were examined. One hundred and sixty-one English-speaking, community-dwelling older adults participated. Results: Reliability evidence is strong based on coefficient alpha and average inter-item correlations. Convergent validity evidence is strong, with significant, moderate to strong correlations with measures of related constructs. Discriminant validity evidence is strong. Discussion: The results of this study provide support for the psychometric properties of the WFPTS with older adults. Future directions for research with this instrument are discussed.
