Preliminary factor analysis of the O'Kelly Women Beliefs Scale in a US sample / Análisis factorial preliminar de la O'Kelly Women Beliefs Scale en una muestra estadounidense

Using a Rational Emotive Behavior Therapy framework, the O'Kelly Women Beliefs Scale (O'Kelly, in press) was originally constructed in Australia to measure sex-role beliefs women may develop through sex-role stereotyping. Factor analysis of the 92 original items showed that 64 items loaded into a single component that accounted for 18.2% of the variance in a sample of 974 Australian women. The present exploratory study examined the psychometric properties of the OWBS in a sample of 202 women born and living in the US. A varimax rotation with cutoff eigenvalues of 3, showed that 37 items loaded into 3 components which accounted for 58.48% of the variance. The items were subsequently grouped into two factors: Irrationality, with a total of 27 items was created by merging component 1 and 3 (Pearson's r = 0.8 between them), and Rationality, with the 10 items from component 2. Analyses indicated a Cronbach's alpha of 0.91 for Factor 1, and a Cronbach's alpha 0.74 for Factor 2. Results indicate that this version of the instrument may be used to evaluate both the rational and irrational content of sex-role beliefs of women born in the US.

En el contexto de la Terapia Racional Emotivo-Conductual, se desarrolló la O'Kelly Women Beliefs Scale (OWBS) construída originalmente en Australia, para evaluar las creencias sobre el rol sexual que las mujeres pueden desarrollar como estereotipo. En una muestra de 974 mujeres australianas, el análisis factorial de los 92 reactivos originales mostró que 64 de ellos cargaron en un solo componente que explica el 18.2 % de la varianza total. El objetivo del presente estudio exploratorio es determinar la estructura factorial del OWBS, en 202 mujeres nacidas en E.E. U.U. La rotación Varimax con punto de corte de autovalor en 3, arrojó que 37 ítems cargan en tres componentes que explican el 58.48 % de la varianza total. Los reactivos se agruparon en dos factores: Irracionalidad, con un total de 27 reactivos que se integraron en los componentes 1 y 3 (r = 0.8) y Racionalidad, con 10 reactivos integrados en el componente 2. El alfa de Cronbach fue de 0.91 para el Factor 1 y de 0.74 para el Factor 2. Los resultados indican que esta versión del instrumento puede ser usada para evaluar tanto el contenido racional como el irracional de las creencias sobre el rol sexual de las mujeres nacidas en E.E. U.U.

Aculturación y diferencias en las creencias irracionales sobre el rol femenino tradicional (O’Kelly Women Beliefs Scale) en mujeres colombianas residentesen su país de origen y en Estados Unidos / Acculturation and differences in the irrational beliefs about traditional female roles (O’Kelly Women Beliefs Scale) in Colombian women living in Colombia and U. S. A

La Escala de Creencias de las Mujeres de O’Kelly (O’Kelly Women Beliefs Scale., O’Kelly, en prensa; Ellis, 1985) fue aplicada a colombianas residentes en Cali, Colombia, colombianas residentes en el noreste de los Estados Unidos y sus contrapartes estadounidenses (20 madres y 20 hijas mayores de 17 años en cada grupo). Se encontró que existen diferencias transculturales en los puntajes totales de los tres grupos. Comparaciones posthoc (LSD) indicaron que las diferencias significativas se encuentran en las hijas colombianas residentes en Estados Unidos, comparadas con las madres colombianas residentes en Colombia y las madres e hijas estadounidenses. No existen diferencias entre madres e hijas colombianas residentes en Estados Unidos. Los resultados sugieren que el patrón deaculturación de los colombianos en los Estados Unidos es el de asimilación al país de adopción conservando aspectos de la tradición y la cultura del país de origen.

The O’Kelly Women Beliefs Scale (O’Kelly, in press) was given to 120 females: Colombians living in Colombia, and Colombians, and their non- Hispanic US counterparts living in the USA (20 mother-daughter pairs in each group). An ANOVA indicated significant cross-cultural differences among the groups, where posthoc comparisons (LSD) revealed they were largely due to differences between Colombian daughters in the USA and three subgroups: Colombian mothers inColombia, non- Hispanic US mothers, and non- Hispanic US daughters. Results suggest that the acculturation patternof Colombians to the USA seems to be one of assimilation to the new culture keeping several aspects of the traditions and costumes of the country of origin.

Interstitial tissue pressure associated with dental injections: a clinical study.

OBJECTIVES: The purpose was to measure the interstitial fluid pressure generated from tissue resistance during administration of local anesthetic solution at 4 anatomic locations within the oral cavity and to determine whether differences in soft tissue density affect interstitial fluid pressure when anesthetic solution is administered at a fixed flow rate. METHOD AND MATERIALS: A computer-controlled local anesthetic delivery device (CompuFlo, Milestone Scientific) that records and stores pressure data during a subcutaneous injection was used. Subjects consisted of adult patients seeking routine dental care that required local anesthesia. A total of 200 injections were administered and fluid pressure readings recorded. Injections were divided into 4 groups of 50: group 1--intraligamentary injections (PDL); group 2--palatal injection, anterior middle superior alveolar nerve block; group 3--supraperiosteal buccal infiltrations, and group 4--inferior alveolar nerve blocks. For all injections 1 cartridge (1.8 mL) of lidocaine containing 1:100,000 concentration of epinephrine was administered at a fixed flow rate of 0.005 mL/sec. RESULTS: One-way analysis of variance (ANOVA) revealed that the data were statistically significant (P < .001), with corresponding mean values as follows: group 1, 293.98 psi; group 2, 68.16 psi; group 3, 11.50 psi, and group 4, 9.76 psi (F-ratio of 2371.933). Groups 1 and 2 were different from all other groups; groups 3 and 4 were not statistically different from each other. CONCLUSION: Interstitial resistance to fluid pressure can be measured during administration of 4 different local anesthetic injections used in dentistry. Based on fluid pressure and tissue resistance characteristics, a soft tissue density classification was defined.

Critical appraisal. Porcelain veneer outcomes, part I.

Etched porcelain veneers have now been used clinically for about 20 years. The profession was originally very skeptical about bonding thin shells of a brittle ceramic material to teeth. However, ceramic veneers have proved to be not only very esthetic but also extremely durable restorations. This two-part Clinical Appraisal reviews several articles related to veneer longevity and clinical factors contributing to--or detracting from--longevity. Part II will appear in the next issue of JERD.

Magnification in a restorative dental practice: from loupes to microscopes.

Dentistry requires precise motor skills guided by keen visual acuity. Many options are available to improve visual acuity--from simple loupes to surgical microscopes. Each has inherent advantages and limitations, but they all help improve precision beyond unaided vision. Data suggests that every dental professional is at risk for an occupational musculoskeletal injury. Clearly, there is a correlation between seeing clearly and maintaining good posture. Using the appropriate visual enhancement should be considered for all dental professionals to make the practice of dentistry more precise, easier, and more enjoyable and to reduce the risk of musculoskeletal injury.
