Positive Affect Moderates the Relationship Between Salivary Testosterone and a Health Behavior Composite in University Females

AbstractBackgroundTestosterone is released in both men and women and plays an important role in social functioning and motivation. Greater testosterone in women has been associated with negative physical health outcomes, while lower testosterone has been associated with psychological disorders. The following cross-sectional study examined the contribution of salivary testosterone, positive and negative affect, and demographic variables in predicting a composite health behavior score (cigarette use, hours of sleep, fruit/vegetable intake, following an exercise routine).MethodThe sample (mean age 21.17,SD = 6.13) consisted of 87 female university students asked to complete a demographic and lifestyle behavior questionnaire, the Positive and Negative Affect Schedule, and provide a saliva sample. Participants self-identified as Latina (37.9%), European American (32.2%), Asian American (5.7%), Afri can American (4.6%), or Mixed/other (19.5%). Hierarchical regression analyses were used to examine whether positive and negative affect served as a moderator between salivary testosterone and a health behavior composite.ResultsResults indicated that positive affect moderated the relationship between salivary testosterone and the composite health behavior score (t = − 2.42,p = .018, Adj.R2 = .21,F (5, 81)  = 5.07,p

Conclusion: Individuals with SCI experience more sleep problems compared to the Swiss GP. Findings from this study suggest that clinical screening for sleep issues targeting high risk groups is needed to reduce the large prevalence of non-treatment in individuals with SCI.

In this study, the effect of CBL on sleep-deprivation induced memory impairment was investigated. Sleep deprivation was induced in rats using the modified multiple platform model (8 hours/day for 4 weeks). Concurrently, CBL was administered intraperitoneally for four weeks. Animal's performance (spatial learning and memory) was assessed using the radial arm water maze (RAWM). Additionally, oxidative stress biomarkers including reduced glutathione (GSH), oxidized Glutathione (GSSG), GSH/GSSG ratio, glutathione peroxidase (GPx), and catalase were assessed in the hippocampus. Current results showed that sleep deprivation impa...

Burdette, Lauren HaleAbstractAlthough there is no empirical evidence linking gun ownership with better sleep, speculation is widespread in gun culture. We assess the direct association between gun ownership and sleep disturbance and whether gun ownership moderates the association between neighborhood fear and sleep disturbance. We use four waves of cross-sectional data from the General Social Survey (2010–2018) and logistic regression to model sleep disturbance as a function of gun own...

The purpose of this pilot study was to assess the efficacy of a psychotherapeutic approach, namely Cognitive Behavioral Therapy for Insomnia (CBT-I), in improving sleep quality in patients with epilepsy. Twenty outpatients with epilepsy who reported poor sleep quality were randomized to either a control or CBT-I treatment...

The objective of this research is to try to understand how masochistic sexual fantasies emerge and what these sexual practices represent for their devotees, in terms of their psychological life and their sexuality. Sixteen subjects answered a questionnaire built on two axes: the sexual practices themselves (from the first fantasies to their implementation in sexuality), and the biographical path of the subjects (life history, relations with the family and the environment). This is a qualitative research, the results of which were treated in the form of thematic analysis and portraits of each subject, to reflect the uniquen...
