Cognitive Psychophysiological Substrates of Affective Temperaments

Affective temperaments are the subclinical manifestations or phenotypes of mood states and hypothetically represent one healthy end of the mood disorder spectrum. However, there is a scarcity of studies investigating the neurobiological basis of affective temperaments. One fundamental aspect of temperament is the behavioral reactivity to environmental stimuli, which can be effectively evaluated by use of cognitive event-related potentials (ERPs) reflecting the diversity of information processing. The aim of the present study is to explore the associations between P300 and the affective temperamental traits in healthy individuals. We recorded the P300 ERP waves using an auditory oddball paradigm in 50 medical student volunteers (23 females, 27 males). Participants' affective temperaments were evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-auto questionnaire version (TEMPS-A). In bivariate analyses, depressive temperament score was significantly correlated with P300 latency ( r_s = 0.37, P < .01). In a multiple linear regression analysis, P300 latency showed a significant positive correlation with scores of depressive temperament (β = 0.40, P < .01) and a significant negative one with scores of cyclothymic temperament (β = -0.29, P = .03). Affective temperament scores were not associated with P300 amplitude and reaction times. These results indicate that affective temperaments are related to information processing in the brain. Depressive temperament may be characterized by decreased physiological arousal and slower information processing, while the opposite was observed for cyclothymic temperament.

When children play, they feel better: organized activity participation and health in adolescents

BACKGROUND

Participation in organized leisure-time activities (OLTA) has been linked to healthy youth development. This study aimed to assess whether participation in OLTA is associated with both physical and mental health in adolescents, and whether this association differs by pattern of activity participation, age and gender.

METHODS

The present study was based on data from the 2013/2014 Health Behaviour in School-aged Children study in the Czech Republic. This data concerned 10,503 adolescents (49.2 % boys) aged 11, 13 and 15. A cluster analysis was carried out to obtain patterns of activity participation and yielded five groups (all-rounders, artists, individual sports, team sports and inactive). The association between participation in types of OLTA and physical and mental health was analysed using logistic regression models adjusted for age and gender. We also assessed interactions between types of OLTA and gender and age.

RESULTS

Participation in OLTA was associated with better self-rated health and higher life satisfaction regardless of gender or age. Participation in team or individual sports was associated with better general health and less frequent health complaints in boys, while participation in art activities was associated with lower occurrence of health complaints in girls and 11-year-olds.

CONCLUSION

Participation in OLTA is associated with better physical and mental health in adolescents. The association varies by pattern of activity participation and is partly gender- and age-specific.

Affective temperaments in subjects with female-to-male gender dysphoria

BACKGROUND

Males and females have different temperaments. In individuals with gender dysphoria (GD) there is marked incongruence between a person׳s expressed/experienced gender and their biological sex. The present study aimed to investigate the most common affective temperaments in individuals with female-to-male (FtM) GD.

METHODS

We performed a prospective and comparative study investigating affective temperaments in subjects with FtM GD. Eighty subjects with FtM GD and 68 female controls were enrolled. The Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A) was completed by all participants.

RESULTS

TEMPS-A scores were significantly higher in subjects with FtM GD for hyperthymic temperament (p≤0.001), whereas depressive (p≤0.001), anxious (p≤0.001), and cyclothymic (p=0.028) temperament scores were significantly higher in female controls.

LIMITATIONS

The study was limited by the lack of male-to-female subjects and male controls.

CONCLUSIONS

The results of our study indicate that individuals with FtM GD have significantly higher scores of hyperthymic temperament, measured by TEMPS-A. Biological basis underlying the development of gender identity independent from the biological sex might be related with affective temperaments.
