Adequate Model Fit Research Articles

Psychometric properties of two psychological restoration scales: translation, adaptation and validity evidences of the Brazilian versions (Propiedades psicométricas de dos escalas de restauración psicológica: traducción, adaptación y validez de las versiones brasileñas)

ABSTRACT Restorative environments refer to settings that allow for the recovery of depleted psychological resources. The potential to promote restoration can vary from place to place according to a setting’s characteristics. Two scales, Perceived Restorativeness Scale and Restoration Outcome Scale, have been applied to measure the restorativeness of places and restorative outcomes in the Global North. This study aims to translate, adapt and analyse the psychometric properties of these scales for their application in Brazil and to test their convergent validity. Our sample is composed of 566 adults (50.7% male) from the cities of Porto Alegre and São Paulo, with ages ranging from 18 to 85 years old. Both scales presented adequate internal consistency and model fit indexes. Moreover, the scales’ fit indexes were considered adequate regardless of participants’ gender and city of residence, which were tested through multigroup confirmatory factor analyses. With this contribution, we expect to help the expansion of research on restorative environments in the poorly studied Global South.

Validity and Reliability of the Baby and Child Eating Behavior Questionnaire, Toddler Version (BEBQ-Mex and CEBQ-T-Mex) in a Low Sociodemographic Sample Recruited in a Mexican Hospital.

The objective of this study was to validate and measure the internal reliability of the Baby and Child Eating Behavior Questionnaires for Toddlers (BEBQ-Mex and CEBQ-T-Mex), that evaluate appetitive trait (ATs). Mothers recruited from a public hospital in Guadalajara, Mexico, completed the BEBQ-Mex or CEBQ-T-Mex along with information on sociodemographic characteristics. Internal reliability of the BEBQ-Mex was sufficient for Food Responsiveness (FR) (Cronbach α = 0.82), while Enjoyment of Food (EF) and Satiety Responsiveness (SR) showed poor reliability (α = 0.56) and Slowness in Eating (SE) had unacceptable reliability (a = 0.36). All reliability values for the CEBQ-T-Mex were acceptable (>0.70), except for SE (α = 0.64). Confirmatory factor analysis (CFA) revealed an adequate model fit for the BEBQ-Mex, except the SE subscale. CFA for the CEBQ-T-Mex confirmed the six-factor structure. Mothers of a low sociodemographic background were unable to recognize their infants’ ATs; the BEBQ-Mex partly met the criteria for validity and reliability. Mothers from similar sociodemographic characteristics were more able to recognize the ATs of their toddlers than their infants; the CEBQ-T-Mex was found to be a valid and reliable tool. Findings support the need to help mothers’ ability to recognize their infants’ ATs, which have been previously associated with weight and growth.

Recovery-oriented acute inpatient mental health care: Operationalization and measurement.

The current article describes efforts to develop and test a measure of recovery-oriented inpatient care. The Recovery-oriented Acute INpatient (RAIN) scale was based on prior literature and current Veterans Health Administration (VHA) policy and resources and further revised based on data collection from 34 VHA acute inpatient units. A final scale of 23, behaviorally anchored items demonstrated a four-factor structure including the following factors: inpatient treatment planning, outpatient treatment planning, group programming, and milieu. While several items require additional revision to address psychometric concerns, the scale demonstrated adequate model fit and was consistent with prior literature on recovery-oriented inpatient care. Conclusions and Implementations for Practice: The RAIN scale represents an important tool for future implementation and empirical study of recovery-oriented inpatient care.

Validating the family coping questionnaire for eating disorders for caregivers of Japanese patients with eating disorders: association between coping strategies and psychological characteristics

BackgroundEating disorders (ED) can adversely affect the psychological health of patients’ caregivers. The present study aimed to validate a Japanese version of the Family Coping Questionnaire for Eating Disorders (FCQ-ED-J) and investigate the association between the coping strategies and psychological states of the caregivers of ED patients.MethodsThe caregivers completed the FCQ-ED-J and the Profile of Mood States. The FCQ-ED measures the coping strategies of caregivers of ED patients to the ED symptom-related behaviors. As confirmatory factor analysis did not yield an adequate model fit, the factor structure of the FCQ-ED-J was analyzed using exploratory factor analysis. Subsequently, the reliability and validity of the FCQ-ED-J were examined using Cronbach’s alpha and Pearson’s correlation coefficients in relation to the Profile of Mood States.ResultsData from 150 caregivers, including 91 mothers and 34 fathers, was analyzed (mean age 51.1 years, SD = 12.0). The FCQ-ED-J, with 13 items grouped across four subscales [“response to binge-eating” (factor 1), “response to frequent weighing” (factor 2), “response to too much physical exercise” (factor 3), and “response to abusing laxatives and/or diuretics” (factor 4)] had Cronbach’s alpha values representing acceptable to good internal consistency (0.71–0.85). Each subscale of the FCQ-ED-J was significantly correlated with the Profile of Mood States subscales.ConclusionsThe FCQ-ED-J had sufficient reliability and validity. The Japanese caregivers’ responses to the patient’s ED symptom-related behavior were associated with their psychological states. Thus, the FCQ-ED-J may offer insight into more effective and reasonable care by caregivers for ED patients.Plain English summaryThe Family Coping Questionnaire has been used by researchers to assess the coping strategies of the relatives of patients. The present study aimed to validate a Japanese version of the Family Coping Questionnaire for Eating Disorders (FCQ-ED-J) and investigate the association between the coping strategies and psychological states of the caregivers of ED patients. Data from 150 caregivers, including 91 mothers and 34 fathers, were analyzed. The FCQ-ED-J comprised 13 items grouped into four subscales, with acceptable to good internal consistency (Cronbach’s alpha values between 0.71 and 0.85). All subscales of the FCQ-ED-J were found to be statistically significantly correlated with the profile of mood states (POMS) subscales. The Japanese caregivers’ responses to the patient’s ED symptom-related behavior were associated with their psychological states. Thus, the FCQ-ED-J can be utilized to help caregivers provide more effective and reasonable psychological care and support to ED patients.

Teachers' Irrational Belief Scale: Psychometric Properties of the Greek Version and Measurement Invariance across Genders.

Irrationality refers to human thoughts and beliefs that signify lack of rationality and entail erroneous perceptions about situational, personal, or collective idiosyncrasies, while it is independent of one’s intellectual ability. Irrational beliefs are ubiquitous in all social and cultural groups and attract a special interest in behavioral sciences, where the primary concern is the development of instruments for identifying and measuring them. The present study evaluates the psychometric properties of Greek version of Teachers’ Irrational Belief Scale (TIBS-G), a 25-item self-reported instrument using data collected from 835 participants. The exploratory procedure, implementing scree plot with parallel analysis, demonstrated the dimensionality of four factors, namely: Self-downing (SD), Authoritarianism (A), Demands for Justice (DJ), and Low Frustration Tolerance (LT). The corresponding reliability measures using Cronbach’s alpha and McDonald’s omega were ranged between 0.70 and 0.80. Subsequently, confirmatory factor analysis showed an adequate fit of the measurement model [χ2 = 579.98, df = 183, p < 0.001; CFI = 0.960; TLI = 0.956; RMSEA = 0.051]. In addition, measurement invariance was performed, which demonstrated differences between genders. Finally, discussion on the importance of irrational beliefs and the possible implementation of the TIBS instrument in educational research is provided.

Measuring psychological flexibility: The cultural adaptation and psychometric properties of the AAQ for substance abuse among Spanish speaking population in correctional and community settings

Evaluating psychological flexibility is key in determining the mechanism of action of an ACT intervention. This study aims to evaluate the psychometric properties of the Spanish version of the Acceptance and Action Questionnaire – Substance Abuse (AAQ-SA), a measure of psychological flexibility, among 402 adults with Substance Use Disorders (SUDs) in Puerto Rico recruited from either a prison population or community treatment settings. To evaluate the factor structure of the AAQ-SA, we conducted confirmatory factor analyses with the two-factor structure proposed by the original authors and the three-factor structure found in a Mexican sample. We found the two-factor structure to be a better fit of the data from our sample. After implementing modifications to the model, the two-factor structure demonstrated adequate model fit indices. To gather evidence of convergent validity, we evaluated correlations between scores of the AAQ-SA and those of depression, self-efficacy, and self-stigma measures. The current study suggests that the AAQ-SA is a promising measure of psychological flexibility for the present target populations. Further research is needed to examine the psychometric properties of scores of the AAQ-SA, including discriminant validity.

Development and Validation of the Indonesian Version of Quality Nursing Work Environment (QNWE-I) Instrument

Background: Nursing shortages are a significant problem experienced by medical institutions worldwide as well as Indonesia. Understanding nurses’ work environment is a proper strategy for enhancing the retention and overcoming shortages of nurses. The Quality Nursing Work Environment (QNWE) is a well-known tool that has been commonly used to evaluate the working atmosphere of nurses. However, the availability and validated version of the instrument for hospital nurses in Indonesia is not confirmed.Purpose: This study aims to confirm the psychometric evaluation of the Indonesian version of QNWE instruments in hospital settings.Methods: A cross-sectional study design and psychometric analyses were administered. The 65-item, eight-domain questionnaire was translated, adapted, and face-validated using content validity index (CVI) analysis. The construct validity and internal consistency of the translated version were tested using confirmatory factor analysis (CFA) and Cronbach's Alpha to 334 hospital nurses. The intraclass correlation coefficient (ICC) was employed to determine test-retest and interrater reliability analysis to 33 nurses and 10 ratters in the pilot testing.Results: The CVI of the QNWE-I scale ranged from 0.86 to 1.00. The CFA determined an adequate model fit of the instrument. As to overall reliability, test-retest reliability of 0.90, ICC analysis of 0.82, and Cronbach's alpha of 0.96; was confirmed.Conclusions: The psychometric evaluation of the QNWE-I showed excellent acceptability, validity, and reliability. Therefore, the QNWE-I can serve as a comprehensive instrument for assessing the quality of nurses' work environments in Indonesia.

Validation of the Amotivation Inventory in Physical Education: exercise level and physical self-concept

Introduction. According to Self-Determination Theory, it is known that motivation is an essential factor for the adherence and enjoyment of exercise, generating long-lasting habits. The importance of generating such habits from an early age is a determining factor in the future health of people. The child and youth population invests a great amount of hours per week in their training in Educational Centers. The objective of this investigation was to adapt the Amotivation Inventory-Physical Education to the Spanish context, in addition to examining its psychometric properties. Method. Two hundred thirty-two boys and girls from 6th grade of Primary Education participated. Ages ranged from 10 to 12 years old (Mage = 10.99; SD = .47). Results. The results of the confirmatory factor analysis showed adequate model fit rates. In addition, the factor structure was shown to be invariant by gender. High levels of internal consistency were obtained and external validity was shown through a linear regression analysis with the variables of physical exercise frequency and physical self-concept as independent to explain amotivation in physical education lessons. Discussion and Conclusion. In conclusion, the scale is shown to be a reliable, gender-invariant and valid measure with both boys and girls in Primary Education.

A-159 Attention and Executive Function Predict Immediate and Delayed Verbal Memory in Healthy Youth: A Structural Equation Modeling Approach

Abstract Objective Previous neuropsychological assessments have sought to understand the interrelatedness of cognitive functions when interpreting neuropsychological test performance (e.g., Delis-Kaplan Executive Function System; DKEFS), given that they rarely function in isolation. Test results may be misinterpreted if not contextualized within individuals’ overall cognitive profiles; therefore, the present study evaluated the impact of attention and executive function (EF) on verbal learning and memory (VLM) in a sample of healthy youth. Method Participants (n = 166, M age = 12.0 years, 79.5% male, M FSIQ = 109.6) completed a two-hour neuropsychological battery, including the Wide Range Assessment of Learning and Memory, 2nd Edition List Learning (LL), DKEFS Trail Making Test (TMT), and Wechsler Intelligence Scale for Children, Fourth Edition Digit Span (DS) and Letter-Number Sequencing (LNS). Structural equation modeling was used to evaluate the impact of attention and EF on immediate and delayed VLM. Results Latent factors were estimated for attention/EF (DS Forward, DS Backward, LNS, and TMT Condition 4) and VLM (LL Trials 1–4), and the model converged with adequate model fit statistics (RMSEA = 0.064; CFI = 0.975; TLI = 0.963, SRMR = 0.039). Attention and EF predicted performance on both immediate and delayed VLM (ps &amp;lt; 0.001) when accounting for age. Conclusions The results demonstrated that attention and EF predicted immediate and delayed VLM in youth, suggesting that participants’ performance on VLM may be impacted by weaknesses in attention and EF. As a result, clinicians are recommended to examine patterns of performances across multiple cognitive domains when interpreting individual test scores. This is especially important in pediatric populations given the developmental changes the brain undergoes during childhood and adolescence.

Development and validation of an occupational health triage tool.

As work and health are closely interlinked, it is important to carefully monitor employees. However, limited resources restrict in-depth follow-up. This study was aimed to develop a low-cost screening instrument for employees' overall health status, that can be used across industries and that allows triaging workers to in-depth health surveillance in case of indications of health or functioning problems. We developed a new questionnaire-based algorithm built on multiple predictors to assess the need for further follow-up. We used a systematic review, Delphi panel (n = 9) and focus group (n = 5) to determine the predictors, tested for language pitfalls in a pilot study and evaluated the questionnaire's validity in two separate studies. Study 1 (n = 60) analysed the discriminatory power of the instrument by comparing it to the assessment of an occupational physician in a sample of employees from diverse occupational settings. Study 2 (n = 869) appraised the factor structure and internal consistency of the screening tool in a sample of employees from the hospital sector. Risk factors, current physical and mental health, functioning, absenteeism, job satisfaction and lifestyle were identified as the most relevant predictors. Study 1 showed the survey had good criterion validity (area under the curve = 0.72). Study 2 (N = 869, 28% response) demonstrated the internal consistency (Cronbach's α = 0.94), and a factor analysis confirmed a second-order factor structure with adequate model fit (comparative fit index = 0.96, root mean square error of approximation = 0.04 and standardized root mean square residual = 0.07). This questionnaire can be used to triage workers for occupational health follow-up and can, additionally, be useful to describe the epidemiology of work-related illness.

Improving the measurement of alexithymia in autistic adults: a psychometric investigation of the 20-item Toronto Alexithymia Scale and generation of a general alexithymia factor score using item response theory

BackgroundAlexithymia, a personality trait characterized by difficulties interpreting emotional states, is commonly elevated in autistic adults, and a growing body of literature suggests that this trait underlies several cognitive and emotional differences previously attributed to autism. Although questionnaires such as the 20-item Toronto Alexithymia Scale (TAS-20) are frequently used to measure alexithymia in the autistic population, few studies have investigated the psychometric properties of these questionnaires in autistic adults, including whether differential item functioning (I-DIF) exists between autistic and general population adults.MethodsThis study is a revised version of a previous article that was retracted due to copyright concerns (Williams and Gotham in Mol Autism 12:1–40). We conducted an in-depth psychometric analysis of the TAS-20 in a large sample of 743 cognitively able autistic adults recruited from the Simons Foundation SPARK participant pool and 721 general population controls enrolled in a large international psychological study. The factor structure of the TAS-20 was examined using confirmatory factor analysis, and item response theory was used to generate a subset of the items that were strong indicators of a “general alexithymia” factor. Correlations between alexithymia and other clinical outcomes were used to assess the nomological validity of the new alexithymia score in the SPARK sample.ResultsThe TAS-20 did not exhibit adequate model fit in either the autistic or general population samples. Empirically driven item reduction was undertaken, resulting in an 8-item general alexithymia factor score (GAFS-8, with “TAS” no longer referenced due to copyright) with sound psychometric properties and practically ignorable I-DIF between diagnostic groups. Correlational analyses indicated that GAFS-8 scores, as derived from the TAS-20, meaningfully predict autistic trait levels, repetitive behaviors, and depression symptoms, even after controlling for trait neuroticism. The GAFS-8 also presented no meaningful decrement in nomological validity over the full TAS-20 in autistic participants.LimitationsLimitations of the current study include a sample of autistic adults that was majority female, later diagnosed, and well educated; clinical and control groups drawn from different studies with variable measures; only 16 of the TAS-20 items being administered to the non-autistic sample; and an inability to test several other important psychometric characteristics of the GAFS-8, including sensitivity to change and I-DIF across multiple administrations.ConclusionsThese results indicate the potential of the GAFS-8 to robustly measure alexithymia in both autistic and non-autistic adults. A free online score calculator has been created to facilitate the use of norm-referenced GAFS-8 latent trait scores in research applications (available at https://asdmeasures.shinyapps.io/alexithymia).

Enacting maturity during adolescence: Extending theory, developing a measure, and considering implications for problem behaviors

A challenge of early adolescence is the “developmental mismatch” between adolescents’ need for autonomy and the lack of opportunities to enact maturity via adult-like roles. We identified ways that young people enact maturity, from a youth perspective via focus groups (N = 41, aged 11–17 years), and used data to develop and test a new measure of enacting maturity (EM) using an online survey (N = 420; aged 11–18 years; 58.6% female; 49.5% White). Exploratory factor analysis suggested four internally consistent factors: Independence, Responsibility, Leadership, and Communication; confirmatory factor analysis resulted in a 21-item scale with adequate model fit. Independence was associated with more substance use and general risk taking while Responsibility and Communication were associated with less substance use and general risk taking. The EM measure is an important first step to understanding if adolescents have opportunities to enact maturity and how this relates to key developmental outcomes.

Dark tourism: motivations and visit intentions of tourists

PurposeThe overall purpose of this study is to utilize the Theory of Planned Behavior (TPB) in combination with four dark tourism constructs (dark experience, engaging entertainment, unique learning experience, and casual interest) to gain a better understanding of behaviors and intentions of tourists who have visited or plan to visit a dark tourism location.Design/methodology/approachA total of 1,068 useable questionnaires was collected via Qualtrics Panels for analysis purposes. Confirmatory Factor Analysis (CFA) was used to verify satisfactory reliability and validity regarding the measurement of model fit. With adequate model fit, structural equation modeling was employed to determine positive and negative relationships between TPB and dark tourism constructs. In all, 11 hypotheses statements were tested within this study.FindingsResults of this study indicate that tourists are curious, interested, and intrigued by dark experiences with paranormal activity, resulting in travel choices made for themselves based on personal beliefs and preferences, with minimal outside influence from others. It was determined that dark experience was the most influential of the dark tourism constructs tested in relationship to attitudes and subjective norm.Research limitations/implicationsThe data collected for this study were collected using Qualtrics Panels with self-reporting participants. The actual destination visited by survey participants was also not factored into the results of this research study.Originality/valueThis study provides a new theoretical research model that merges TPB and dark tourism constructs and established that there is a relationship between TPB constructs and dark tourism.

Psychometric Properties of Three Measures of Stigma Among Hispanics with Depression.

While many measures of mental illness stigma have been developed, few have been validated in Hispanic populations. This study examined the psychometric properties of three stigma measures (Stigma Concerns about Mental Health Care [SCMHC], Social Distance Scale [SDS], and Latino Scale for Antidepressant Stigma [LSAS]) among a depressed, Hispanic sample. Data were collected during baseline assessments for two studies taking place in primary care settings (N = 500). Psychometric and factor validity were tested for each measure. Confirmatory factor analyses indicated adequate model fit, and adequate internal consistency reliability was found for all three measures. Stigma scores significantly differed by education level and gender. Findings from this analysis provide support for the use of the SCMHC, SDS, and LSAS in a depressed, Hispanic population. Assessing barriers to depression treatment, including stigma, are critical in engaging Hispanics in care and eliminating disparities for the population.

Examination of the Social Emotional Assets and Resilience Scales (SEARS) Youth Report: Factor Structure, Measurement Invariance, and Validity.

The Social and Emotional Assets and Resilience Scale (SEARS) is a promising instrument for prediction of resilience in youth; however, there is limited data to support its use. The purpose of the current study was to examine the factor structure, measurement invariance, internal consistency, and validity of the SEARS-Adolescent Report in youth 8 to 20 years of age. Two hundred and twenty-five childhood cancer survivors (Mage = 15.9, SD = 4.2; 51.4% male; 74.5% White) and 122 student controls without history of significant health problems (Mage = 14.2, SD = 3.5; 54.1% female; 79.5% White) 8 to 20 years of age completed the SEARS-A. The SEARS-A was found to have an adequate factor structure and model fit (χ2 = 1215.5, p < .001; root mean square error of approximation = .057; comparative fit index = .95; standardized root mean square residual = .06) and demonstrated invariance across domains of age, health status, gender, race, and socioeconomic status (Δ comparative fit index < -0.01). It also demonstrated excellent internal reliability, criterion validity, and current validity when compared with another well-established measure of psychological adjustment. As such, the SEARS-A has potential to be a useful, valid, and psychometrically sound tool for predicting social-emotional adjustment outcomes among at-risk youth 8 to 20 years of age.

Development and validation of the Multidimensional Cognitive Attentional Syndrome Scale (MCASS).

The cognitive attentional syndrome (CAS), a multidimensional construct that consists of maladaptive forms of self-regulation, is central to the metacognitive model. Despite the CAS's central importance to the metacognitive model, as well as evidence that components of the CAS are risk factors for the development of emotional disorders, a psychometrically sound self-report measure that accounts for the multidimensional nature of the CAS has yet to be developed. The present set of studies details the development and initial validation of the Multidimensional Cognitive Attentional Syndrome Scale (MCASS). In study 1, a pool of 69 items, assessing the seven self-regulation strategies of the CAS, was administered to U.S. adults recruited through a crowd-sourcing website (N = 323). Structural analyses supported the proposed 7-factor solution and three items with the highest loadings on each factor, without salient cross-loadings, were retained. In Study 2, adult participants (N = 389) completed a battery of self-report measures, including the retained 21 MCASS items. The reduced item pool was examined using both first- and second-order measurement models. The 7-factor first-order measurement model and the second-order measurement model, with each of the first-order factors loading on a higher-order construct (i.e., CAS), provided adequate model fit. Each of the seven, first-order factors exhibited significant loadings on the second-order construct. Convergent, discriminant, and concurrent validity analyses further supported the construct validity of the MCASS scale scores. The MCASS may be particularly useful for examining the theoretical underpinnings of the metacognitive model, as well as for more comprehensive clinical monitoring of the CAS.

The HEX-ACO-18: Developing an Age-Invariant HEXACO Short Scale Using Ant Colony Optimization

In this study, we developed an age-invariant 18-item short form of the HEXACO Personality Inventory for use in developmental personality research. We combined the item selection procedure ant colony optimization (ACO) and the model estimation approach local structural equation modeling (LSEM). ACO is a metaheuristic algorithm that evaluates items based on the quality of the resulting short scale, thus directly optimizing criteria that can only be estimated with combinations of items, such as model fit and measurement invariance. LSEM allows for model estimation and measurement invariance testing across a continuous age variable by weighting participants, rather than splitting the sample into artificial age groups. Using a HEXACO-100 dataset of N = 6,419 participants ranging from 16 to 90 years of age, we selected a short form optimized for model fit, measurement invariance, facet coverage, and balance of item keying. To achieve scalar measurement invariance and brevity, but maintain construct coverage, we selected 18 items to represent three out of four facets from each HEXACO trait domain. The resulting HEX-ACO-18 short scale showed adequate model fit and scalar measurement invariance across age. Furthermore, the usefulness and versatility of the item and person sampling procedures ACO and LSEM is demonstrated.

Validation of a Chinese version of the five facet mindfulness questionnaire and development of a short form based on item response theory

This research aimed to validate a Chinese version of the Five Facet Mindfulness Questionnaire (FFMQ-C) and develop a short form based on classic test theory and Item Response Theory (IRT). 539 participants were recruited for the study, with 499 of them yielding valid data. The age range of the participants was from 18 to 71 years. Results demonstrated high test-retest reliability and high internal consistency of FFMQ-C. Based on the full-scale results, a 15-item short-form scale (FFMQ-C-SF) was developed using both classic test theory and IRT. The short form also had good internal consistency. Confirmatory factor analysis (CFA) supported the five-factor structure of the FFMQ-C and FFMQ-C-SF with adequate model fit. Validity was indicated by significant correlations between the two mindfulness scales and theoretically related constructs (e.g., emotional intelligence and experiential avoidance). Our findings indicate that FFMQ-C and FFMQ-C-SF can be used to measure mindfulness among the Chinese population.

Development and validation of a latent, multidimensional, self-report periodontal disease measure.

Self-report measures of periodontal disease have utility for screening, but have not capitalized on a latent variable approach based on psychometric theory to validate such measures. This study aimed to develop a psychometrically valid self-report measure of periodontal disease using latent variable factor analysis and other evidence-based psychometric analyses. Likert-type items reflecting periodontal disease were administered to a sample of adults (n=828) in the United States via an online survey. Items were adapted from prior self-report measures or were newly developed based on psychometric item development theory and theoretical knowledge of periodontal disease. Psychometric analyses included exploratory and confirmatory factor analysis, parallel analysis, and a calculation of internal consistency. Exploratory factor analysis (EFA) was indicative of the goodness-of-fit with two factors (root mean square error of approximation (RMSEA)=0.08; comparative fit index (CFI)=0.97; Tucker Lewis index (TLI)=0.96; standardized root mean squared residual=0.06); five of the 22 original survey questions were eliminated based on the results of this EFA. Parallel analysis supported a two-factor model to represent the similarities across items-one factor reflecting physiologic components and another reflecting functional components of periodontal disease. Confirmatory Factor Analysis also indicated adequate model fit (RMSEA=0.07; CFI=0.98; TLI=0.98; and weighted root mean square residual=1.20). Psychometric analyses of a new 17-item periodontal disease self-report measure provided initial evidence of construct/factor validity. This approach to developing self-report periodontal disease measures may facilitate useful and cost-effective estimates of periodontal disease and provide a testable scale. Future work should include clinical validation.
