“…Hoaki et al (2011) reported that more hyperthymic participants receive more light. In addition, more hyperthymic participants prefer brightness and dislike darkness compared with less hyperthymic participants, suggesting the presence of heliotropism (Harada et al, 2013). These findings suggest that the sunshine mediates the positive effect of latitude on the hyperthymic temperament.…”

Background: Previously, we compared the hyperthymic scores of residents in Sapporo, Koshigaya, and Oita (which are located at latitudes of 43˚N, 36˚N, and 33˚N in Japan, respectively) using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire version (TEMPS-A). We found that residents who lived at lower latitudes had higher hyperthymic temperament scores; however, the mechanism of the effect of latitude on hyperthymic temperament remained unclear. The current study examined the mediators of the latitude effect in additional regions with different annual temperatures and amounts of ambient sunshine.Methods: The Japanese archipelago stretches over 4000 km from north to south and has four large islands: Hokkaido, Honshu, Shikoku, and Kyushu. In addition to the TEMPS-A previously reported data collected at Sapporo (latitude 43˚N), Koshigaya (36˚N), and Oita (33˚N), we collected the TEMPS-A data of 189 and 106 residents from Takaoka (36˚N) and Obihiro (42˚N), respectively.Taken together, these five regions have different patterns (i.e., highs and lows) of annual ambient total sunshine (hours) and mean temperature (˚C). The effect of latitude, sunshine, and temperature on affective temperaments was analyzed for five Japanese regions. Results:Multiple regression analyses revealed that latitude predicted significant variance in hyperthymic temperament. Ambient temperature, but not sunshine, significantly affected hyperthymic temperament. Limitations:The light exposure that residents actually received was not measured. The number of regions studied was limited. The findings might not generalize to residents across Japan or other countries. Conclusions:The present findings suggest that latitude affects hyperthymic temperament, and ambient temperature might mediate this effect.

“…As previously detailed (Harada et al, 2013a(Harada et al, , 2013b, we used the Temperament Scale of Memphis, Pisa, Paris and San DiegoAutoquestionnaire (TEMPS-A) developed by Akiskal et al (2005) to measure affective temperament. This scale has 110 questions that gauge 5 temperaments (depressive, hyperthymic, cyclothymic, irritable and anxious), has been verified in 32 languages, and has been widely used in a number of epidemiological and clinical studies with psychiatric patients and healthy subjects.…”

“…Both the brightness judgment task (Harada et al, 2013a) and the brightness preference task (Harada et al, 2013b) used the same blocks consisting of a sequence of 11 blank screens (with 11 levels of indirect illuminance in the absence of any figure) adjusted by tristimulus value (Red, Green, and Blue: 0-250) with each blank screen gradating from white to black by 25 tristimulus value (Fig. 1).…”

“…Following from previous experimental studies examining brightness judgment (Harada et al, 2013a) and brightness preference (Harada et al, 2013b) in relation to hyperthymic temperament, we newly examined reaction time (RT) data generated from these experiments to investigate the hypothesis that hyperthymic temperament is associated with rapid processing in decisions of requiring subjects to judge and indicate preferences of illuminance. Moreover, the previous studies (Harada et al, 2013a(Harada et al, , 2013b suggest the left inferior orbitofrontal cortex as one of neural correlates of hyperthymic temperament and therefore percent signal changes of the region of interest (ROI) were measured and analyzed in relation to RT.…”

Aims:The aim of the study was to check the prevalence of unipolarity (depression), bipolarity, as well as the quality of sleep and temperament traits in patients with type 1 diabetes (T1DM) who are provided with optimal conditions of diabetes care and to identify possible risk factors connected with affective traits. Materials and Methods: Out of the 107 T1DM patients, 78 (54 females, 24 males) were included for the analysis (HbA1c [%] 7.11 � 1.0, BMI [kg/m 2 ] 25.3 � 5.6; Years of disease duration [N] 13.7 � 8.3). The patients filled in a set of questionnaires during their regular visit to the outpatient clinic. Three patients from the whole group were on intensive insulin therapy with Multiple Daily Injections (MDI) and Self-Monitoring of Blood Glucose (SMBG), all the rest were on various types of personal insulin pumps (years on insulin pump [N] 9.1 � 4.5). All the patients were on regular diabetologist care, with regular visits in a Centre for Advanced Technologies in Diabetes (at least every 6 months). Results:In QIDS-S (full explanation and abbreviation 26 patients (33.8%) were screened positive for depression, in PHQ (full explanation and ab 57.7% of the patients (45 patients) had symptoms of depression (age was negatively correlated with PHQ score [r = −0.26; p = 0.023]). In CES-D 16 (20%) of the patients assessed their present affect as depressed. None of the analysed clinical variables correlated with depression scores. In the Mood Disorder Questionnaire (MDQ), 16 patients reported having symptoms of bipolarity (20.5% vs. 79.5%). Hypomania Checklist (HCL) analysis indicated 10 patients with bipolar traits (>14) (14.9% vs. 85.1%).None of the analysed clinical variables correlated with HCL results. 11.5% of patients were indicated to be of morning type. Morningness was more often seen in younger patients (r = 0.39; p = 0.001). As many as 46.6% declared that they had poor sleep quality. The temperament traits analysis correlated with clinical parameters: Cyclothymic temperament trait was negatively correlated with age (r = −0.30; p = 0.007) and positively with HbA1c level (r = 0.30; p = 0.025).Hyperthymic temperament was positively correlated with (BMI r = 0.28; p = 0.016).
