The sexual inhibition (SIS) and sexual excitation (SES) scales: I. Measuring sexual inhibition and excitation proneness in men

This study involves the development and initial validation of a questionnaire measuring the propensity for sexual inhibition and excitation in men: the Sexual Inhibition & Sexual Excitation Scales (SIS/SES). The underlying theoretical model postulates that sexual response and associated behavior depend on dual control mechanisms, involving excitatory and inhibitory neurophysiological systems. The scales and their discriminant and convergent validity and test‐retest reliability are described. In a sample of 408 sexually functional men (mean age = 22.8 years), factor analyses identified three higher‐level factors: two related to sexual inhibition and one to sexual excitation. Multigroup Confirmatory Factor Analyses revealed that the factor structure provided an acceptable fit to the data obtained in a second (N = 459; mean age = 20.9 years) and third (N = 313; mean age = 46.2 years) sample of men, with similar distributions and relationships with other measures. Theoretical issues and areas for further research, including male sexual dysfunction and risk taking, are discussed.     

Women's Scores on the Sexual Inhibition/Sexual Excitation Scales (SIS/SES): Gender Similarities and Differences

Theory and research agree that connectedness to the lesbian, gay, bisexual, and transgender (LGBT) community is an important construct to account for in understanding issues related to health and well-being among gay and bisexual men. However, the measurement of this construct among lesbian and bisexual women or racial and ethnic minority individuals has not yet been adequately investigated. This study examined the reliability and validity of an existing measure of connectedness to the LGBT Community among a diverse group of sexual minority individuals in New York City, and whether differences in connectedness existed across gender and race or ethnicity. Scores on the measure demonstrated both internal consistency and construct stability across subgroups defined by gender and race or ethnicity. The subgroups did not differ in their mean levels of connectedness, and scores on the measure demonstrated factorial, convergent, and discriminant validity, both generally and within each of the subgroups. Inconsistencies were observed with regard to which scores on the measure demonstrated predictive validity in their associations with indicators of mental health and well-being. The scale is a useful tool for researchers and practitioners interested in understanding the role of community connectedness in the lives of diverse populations of sexual minority individuals.     

Women's scores on the sexual inhibition/sexual excitation scales (SIS/SES): gender similarities and differences

The Sexual Inhibition/Sexual Excitation Scales (SIS/SES) assess individual propensities to become sexually aroused and to inhibit arousal. Prior analyses of men's SIS/SES data (Janssen, Vorst, Finn, & Bancroft, 2002a) yielded one excitation factor (SES) and two inhibitory factors (SIS1/Threat of Performance Failure and SIS2/Threat of Performance Consequences). The current study utilized a dataset of 2,045 undergraduates (1,067 women and 978 men) to examine the psychometric properties of women's SIS/SES scores. Women scored higher on sexual inhibition and lower on sexual excitation compared with men. The convergent/discriminant validity of women's SIS/SES scores globally resembled men's, but showed stronger associations with other sexuality - related measures and less pronounced relationships with measures of general behavioral approach/avoidance. The test-retest reliability of men's and women's SIS/SES scores were similar, but individual items exhibited differential relevance to men's and women's arousal. An exploratory factor analysis of women's scores was utilized to further examine shared and unshared themes.     

A Novel Time Series Approach to Bridge Coding Changes with a Consistent Solution Across Causes of Death

Revisions of the International Classification of Diseases (ICD) can lead to biases in cause-specific mortality levels and trends. We propose a novel time series approach to bridge ICD coding changes which provides a consistent solution across causes of death. Using a state space model with interventions, we performed time series analysis to cause-proportional mortality for ICD9 and ICD10 in the Netherlands (1979–2010), Canada (1979–2007) and Italy (1990–2007) on chapter level. A constraint was used to keep the sum of cause-specific interventions zero. Comparability ratios (CRs) were estimated and compared to existing bridge coding CRs for Italy and Canada. A significant ICD9 to ICD10 transition occurred among 13 cause of death groups in Italy, 7 in Canada and 3 in the Netherlands. Without the constraint, all-cause mortality after the classification change would be overestimated by 0.4 % (NL), 0.03 % (Canada) and 0.2 % (Italy). The time series CRs were in the same direction as the bridge coding CRs but deviated more from 1. A smooth corrected trend over the ICD-transition resulted from applying the time series approach. Comparing the time series CRs for Italy (2003), Canada (1999) and the Netherlands (1995) revealed interesting commonalities and differences. We demonstrated the importance of adding the constraint, the validity of our methodology and its advantages above earlier methods. Applying the method to more specific causes of death and integrating medical content to a larger extent is advocated.
