The associations of sexual desire, daily stress, and intimacy in gay men in long-term relationships.

We investigated the associations between daily stress, sexual desire and intimacy in gay men in long-term relationships. A daily diary method of data collection was used. Twenty-two adult participants completed brief questionnaires ten times per day during seven consecutive days. Multilevel regression analyses revealed significant negative associations of daily stress with sexual desire (p = 0.003); higher stress came with lower levels of sexual desire, and vice versa. The hypothesized moderation effect of the associations of stress with sexual desire by intimacy was found significant (p = 0.003). However, the effect was not as predicted: at higher levels of intimacy the negative effect of stress on sexual desire was shown to be stronger than at lower levels. Most temporal associations of stress and intimacy with sexual desire were not significant. Nevertheless, the present findings implicate that daily stress and intimacy are important factors in sexual functioning of gay men in long-term relationships.

Development and Diagnostic Accuracy of a Shortened Dutch Naming Test for People with Aphasia Using Item Response Theory.

OBJECTIVE: The first objective was to assess the psychometric properties of the 92-item Dutch Naming Test (DNT-92), developed to assess word finding difficulties in people with aphasia, using Item Response Theory (IRT). The second objective was to select suitable items for a short version with a discriminative purpose. METHOD: This study has a retrospective, psychometric research design, in which 510 DNT-92-forms of people with aphasia and 192 DNT-forms of healthy participants were used for analyses. An IRT analysis was performed and information on the item- and person parameters was obtained. Item selection for the short version was based on a combination of the discriminative ability of the items and their estimated theta or difficulty. Items with the highest information load, and a difficulty parameter in the range of overlap between the sample of people with aphasia and healthy participants were selected. RESULTS: A 2-PL IRT analysis showed best fit to the data. Assumptions of unidimensionality, local independence, and monotonicity were met. Items were removed incrementally, whilst checking sensitivity and specificity of the remaining short form. A selection of six items proved optimal in terms of sensitivity and specificity, with an area under the curve value of 0.85. Differences were found between participants younger than 70 and older. CONCLUSIONS: The IRT assumptions for the DNT-92 were met, indicating that the test has good psychometric properties. A reduction of items to just six items proved possible, leading to a reliable six item short form with a discriminatory purpose.

The Relation of Mood and Sexual Desire: An Experience Sampling Perspective on the Dual Control Model.

We investigated the effect of fluctuations in negative and positive affect on momentary sexual motivation in a sample of women and men in a steady relationship (n = 133). Sexual motivation was regarded as the aggregate of sexual desire, subjective sexual arousal and openness to sexual contact. Experience sampling methodology was used to collect up to 70 measurements per participant over a period of seven consecutive days of sexual motivation, and negative and positive affect. Using multilevel analysis, we investigated cross-level interactions between affect and trait measures as specified in the dual control model (DCM). This model postulates sexually excitatory and inhibitory mechanisms as relatively independent systems that together can explain individual differences in sexual motivation and behavior. Results implicated that any intensification of feelings, positive or negative, was associated with a momentary increase in sexual motivation for participants more prone to sexual excitation. In the lagged analysis, higher preceding negative affect, measured 1-2 h earlier, forecasted an increase in current sexual motivation for participants more prone to sexual excitation. The lagged analysis included the autoregressive effect or inertia of sexual motivation. Inertia reflects the extent to which sexual motivation lingers and persists at similar levels. Our findings showed that sexual motivation levels persisted less in individuals with higher sexual inhibition proneness due to threat of performance failure. This study demonstrated how experience sampling methodology can be used to extend research on associations between mood and sexual motivation and implicates that DCM factors moderate these associations.

Three Diagnoses for Problematic Hypersexuality; Which Criteria Predict Help-Seeking Behavior?

This study aimed to assess the best combination of indicators of problematic hypersexuality (PH), in a survey (n = 58,158) targeting individuals wondering if they were sex addicted. The survey allowed for testing of criteria from three theoretical models used to conceptualize PH. Factor analyses for women and men yielded an interpretable grouping of indicators consisting of four factors. In subsequent logistic regressions, these factors were used as predictors for experiencing the need for help for PH. The factors Negative Effects and Extreme positively predicted experiencing the need for help, with Negative Effects as the most important predictor for both women and men. This factor included, among others, withdrawal symptoms and loss of pleasure. The Sexual Desire factor negatively predicted the need for help, suggesting that for the targeted population more sexual desire leads to less PH. The Coping factor did not predict experiencing the need for help. Outcomes show that a combination of indicators from different theoretical models best indicates the presence of PH. Therefore, a measurement instrument to assess existence and severity of PH should consist of such a combination. Theoretically, this study suggests that a more comprehensive model for PH is needed, surpassing existing conceptualizations of PH.
