RESUMEN
Despite increased interest in consensual non-monogamy (CNM), significant stigma remains against CNM. Consequently, there is a need for scales to assess attitudes toward CNM. In response to this need we developed the Multidimensional Attitudes toward CNM Scale (MACS). Items were developed in consultation with content experts and data were collected from two samples at two different Canadian Universities. Fit indices of exploratory (Sample A) and confirmatory (Sample B) factor analysis suggested a 16-item scale with three underlying factors: CNM is Dysfunctional, CNM is Immoral, and CNM is Healthy and Satisfying. Validity analyses, conducted using the combined sample (n = 806; 79% women; 67% heterosexual), demonstrated that participants with higher MACS total scores (i.e. more negative attitudes) were less likely to have ever been involved in a CNM relationship and were more likely to report monogamy as their ideal relationship style. Higher MACS scores were also associated with more negative attitudes toward bisexuality and toward women, and higher scores on measures of homophobia and jealousy. In contrast, individuals with higher scores on the CNM is Healthy subscale tended to score higher on measures of empathy. The MACS demonstrates strong psychometric properties and can assist in better understanding attitudes toward CNM relationships in research and clinical settings.
RESUMEN
OBJECTIVES: The aim was to compare the accuracy of five flat panel monitors for detection of approximal caries lesions. METHODS: Five flat panel monitors, Mermaid Ventura (15 inch, colour flat panel, 1024 x 768, 32 bit, analogue), Olórin VistaLine (19 inch, colour, 1280 x 1024, 32 bit, digital), Samsung SyncMaster 203B (20 inch, colour, 1024 x 768, 32 bit, analogue), Totoku ME251i (21 inch, greyscale, 1400 x 1024, 32 bit, digital) and Eizo FlexScan MX190 (19 inch, colour, 1280 x 1024, 32 bit, digital), were assessed. 160 approximal surfaces of human teeth were examined with a storage phosphor plate system (Digora FMX, Soredex) and assessed by seven observers for the presence of caries lesions. Microscopy of the teeth served as validation for the presence/absence of a lesion. RESULTS: The sensitivities varied between observers (range 7-25%) but the variation between the monitors was not large. The Samsung monitor obtained a significantly higher sensitivity than the Mermaid and Olórin monitors (P<0.02) and a lower specificity than the Eizo and Totoku monitors (P<0.05). There were no significant differences between any other monitors. The percentage of correct scores was highest for the Eizo monitor and significantly higher than for the Mermaid and Olórin monitors (P<0.03). CONCLUSIONS: There was no clear relationship between the diagnostic accuracy and the resolution or price of the monitor. The Eizo monitor was associated with the overall highest percentage of correct scores. The standard analogue flat panel monitor, Samsung, had higher sensitivity and lower specificity than some of the other monitors, but did not differ in overall accuracy for detection of carious lesions.
