“…In addition to Kaiser's eigenvalue of 1 criterion and examination of the scree plot, Horn's parallel analysis with Glorfeld's Monte Carlo extension (Dinno, 2009;Glorfeld, 1995;Horn, 1965) was used to identify the optimal number of factors to retain for the final factor solution. Through generation of a large number of random data sets based on the number of subjects and variables of the target data set, parallel analysis compares the eigenvalues from the random data sets with the target data set to determine the optimal number of factors to retain.…”

The entry for nonsuicidal self-injury (NSI) disorder in the 5th edition of the Diagnostic and Statistical Manual o f Mental Disorders provides a criterion-based definition of clinically relevant NSI. NSI disorder is currently classified in the DSM-5 as a condition requiring further study. The present study aimed to examine the reliability, validity, and clinical utility of a self-report measure of NSI disorder, the Alexian Brothers Assessment of Self-Injury (ABASI). The sample included 511 patients admitted to an acute care treatment program designed to treat NSI. Patients were administered the ABASI as part of a clinical assessment and routine outcome evaluation. The sample included a broad age range, as well as sufficient numbers of males and Hispanics to examine sociodemographic differences. The ABASI demonstrated adequate internal consistency and test-retest reliability, and the factor structure reflects NSI disorder criteria. Among patients being treated for NSI, 74% met criteria for NSI disorder. No differences in the rate of NSI disorder were observed by sex, ethnicity, or age. Although NSI disorder is associated with a worse presentation of self-injurious behavior, NSI disorder provides limited clinical utility as a dichotomous diagnosis, at least when compared with common NSI characteristics such as number of methods of NSI and the urge to self-injure. Instead, findings support a dimensional approach to NSI disorder. Analyses of specific symptoms of NSI disorder indicate concerns with Criterion B as currently defined by the DSM-5. Recommendations for a more parsimonious revision of NSI disorder are discussed.

“…We applied two decision rules to determine whether there was sufficient evidence for combining survey items into a composite index including a Kaiser-Meyer-Olkin Measure and a Bartlett’s Test of Sphericity [29]. We conducted a parallel analysis test to determine the number of factors to retain by comparing the observed eigenvalues extracted from the correlation matrix analyzed with those obtained from uncorrelated normal variables [30]. Based on the results, we retained one factor.…”

Providers’ preferences for pediatric oral health information in the electronic health record: a cross-sectional survey

et al. 2018

BackgroundThe majority of primary care physicians support integration of children’s oral health promotion and disease prevention into their practices but can experience challenges integrating oral health services into their workflow. Most electronic health records (EHRs) in primary care settings do not include oral health information for pediatric patients. Therefore, it is important to understand providers’ preferences for oral health information within the EHR. The objectives of this study are to assess (1) the relative importance of various elements of pediatric oral health information for primary care providers to have in the EHR and (2) the extent to which practice and provider characteristics are associated with these information preferences.MethodsWe surveyed a sample of primary care physicians who conducted Medicaid well-child visits in North Carolina from August – December 2013. Using descriptive statistics, we analyzed primary care physicians’ oral health information preferences relative to their information preferences for traditional preventive aspects of well-child visits. Furthermore, we analyzed associations between oral health information preferences and provider- and practice-level characteristics using an ordinary least squares regression model.ResultsFewer primary care providers reported that pediatric oral health information is “very important,” as compared to more traditional elements of primary care information, such as tracking immunizations. However, the majority of respondents reported some elements of oral health information as being very important. Also, we found positive associations between the percentage of well child visits in which oral health screenings and oral health referrals are performed and the reported importance of having pediatric oral health information in the EHR.ConclusionsIncorporating oral health information into the EHR may be desirable for providers, particularly those who perform oral health screenings and dental referrals.

“…To determine the factors underlying ratings, we conducted principal-components analyses 1 using the principal procedure (Revelle, 2009) from the R statistics package (R Development Core Team, 2008) and determined the number of components by examining the scree plot and by using R's paran function (Dinno, 2008) to conduct a parallel analysis (Horn, 1965). We then used a varimax rotation to obtain orthogonal components and a promax procedure to obtain oblique components.…”

Personality dimensions capturing individual differences in behavior, cognition, and affect have been described in several species, including humans, chimpanzees, and orangutans. However, comparisons between species are limited by the use of different questionnaires. We asked raters to assess free-ranging rhesus macaques at two time points on personality and subjective well-being questionnaires used earlier to rate chimpanzees and orangutans. Principal-components analysis yielded domains we labeled Confidence, Friendliness, Dominance, Anxiety, Openness, and Activity. The presence of Openness in rhesus macaques suggests it is an ancestral characteristic. The absence of Conscientiousness suggests it is a derived characteristic in African apes. Higher Confidence and Friendliness, and lower Anxiety were prospectively related to subjective well-being, indicating that the connection between personality and subjective well-being in humans, chimpanzees, and orangutans is ancestral in catarrhine primates. As demonstrated here, each additional species studied adds another fold to the rich, historical story of primate personality evolution.
