Traditional Schedules

Shiftwork causes a number of physical and psychological problems. As a result, we predicted depression to be worse for shiftworkers than for workers with more traditional schedules. In addition, we predicted that women would report more depressive symptoms than men as is the case in the general population. Questionnaire packets which included the Beck Depression Inventory were mailed to 153 workers in a small community. Analysis showed that, contrary to expectation, shiftworkers as a group suffered no more depressive symptoms than traditional workers. However, while both sexes had similar mean scores on depression among the shiftworkers, women were significantly more depressed than men among traditional workers.

Abstract Introduction Depression is prevalent among nursing students. Rumination and sleep-wake rhythms are associated to mental illness; however, no clear path has been found. This exploratory study aimed to examine the associations among circadian activity rhythms (CAR), rumination, and depressive symptoms in female nursing students; further, to test a hypothesized CAR conceptual model. Methods A total of 148 female nursing junior students in China completed a battery of questionnaires, including Athens Insomnia Scale (AIS), Ruminative Responses Scale (RRS), and Self-rating Depression Scale (SDS). Wrist actigraphy was used to collect total sleep time, CAR, and acrophase (time of the peak of the fitted activity curve). The path analysis was explored by using SPSS and AMOS. Results The mean age of the students was 20.64 years (SD = 0.86). About 58.8% of the participants were either mild or moderate depressed. About 93.9% of the students reported significant insomnia symptoms (AIS scores >6). Rumination was measured by the RRS (M= 2.01, SD = 0.54), and students scored higher in brooding than that of reflective pondering (2.07 vs. 1.95). The average of TST was 394.59 minutes (SD = 51.92). The CAR ranged from 0.40 to 0.98, with a mean of 0.75 (SD = 0.11). The acrophase ranged from 12:46 to 20:14 (median 16:30), with a later acrophase indicates of a more delayed circadian phase. The final model shows satisfactory fit (χ2= 2.238, p= .327); a better CAR can indirectly reduce depressive symptoms by directly reducing brooding (B = -1.149) and improving insomnia symptoms (B = -6.6443). Conclusion In order to prevent psychological problems of nursing students, ruminating and CAR should be part of health screening. The novel conceptual model provides a basis for reforming nursing education to prevent psychological problems. Support (if any) Chinese National Natural Science Foundation [71603279]

Background. The microbiome-derived trimethylamine-N-oxide (TMAO) and the intestinal permeability marker zonulin are considered to be linked with depression. Moreover, carbohydrate malabsorption (CMA) was shown to be associated with signs of depression. This study is aimed at investigating possible sex-specific associations between TMAO and zonulin and the presence of depressive signs in individuals with and without CMA. Methods. Serum concentrations of TMAO and zonulin were determined in 115 and 136 individuals with the presence or absence of CMA. All 251 study participants underwent lactase gene C/T-13910 polymorphism genotyping and fructose H2/CH4 breath testing. Additionally, they filled in the Beck Depression Inventory (BDI-II) questionnaire. Results. The median TMAO and zonulin serum concentrations were 2.66 (1.93–4.14) μmol/L and 40.83 (34.73–47.48) ng/mL. Serum TMAO levels were positively correlated with depressive symptoms (P=0.011, ρ=0.160). The strongest correlations were observed in 87 females (P=0.010, ρ=0.274) and 49 males (P=0.027, ρ=0.315) without CMA, whereas 115 patients with CMA showed no significant correlations. Zonulin tended to be negatively correlated with the BDI-II score in 49 males without CMA (P=0.062, ρ=−0.269). Conclusion. This study demonstrates a positive correlationship between the serum TMAO concentrations and the severity of depressive symptoms in females and males without CMA. Serum zonulin levels were negatively correlated with signs of depression in males without CMA. These findings suggest a gender-specific relationship between the serum TMAO and zonulin concentrations, depression, and CMA.

The prevalence of depressive symptoms was estimated in a random sample of an Australian general population by administration of the Zung Self-Rating Depression Scale (S.D.S.). Rates, calculated according to criteria derived from a previously studied clinical sample, were somewhat higher in this population than had been reported in similar studies elsewhere. It was reasoned that this finding related to the relative laxity of criteria employed in the present study. Socio-demographic influences on the reporting of depressive symptoms were evident, the most prominent of these being the sex of the subject. It was suggested that these influences may underlie socio-demographic differences in rates of recognized depressive states occurring within clinical samples.

SummaryPurposeDepressive disorders (DD) in adolescence are often misdiagnosed and under-recognised. A major clinical problem regards the high rate of co-morbidity with other disorders, namely substance abuse. The aim of this study was to assess the discriminative power of the Beck Depression Inventory II (BDI-II) to characterise specific social–demographic variables related to DD in adolescence.MethodsA Portuguese version of the BDI-II and a social–demographic questionnaire were administered to 775 Portuguese adolescents (312 males, 463 females; mean age: 16.9 years); 83 adolescents performed a clinical interview following DSM-IV criteria.ResultsMean BDI-II Portuguese version (BDI-II-P) total score was 10.31 (standard deviation: 8.4), with females reporting more depressive symptoms than males (P < 0.001). Low academic achievement, sleep disturbances, and alcohol consumption were consistently associated with depressive symptoms for both genders. Higher tobacco consumption was significantly associated with depressive symptoms in females. Familial factors did not appear to be associated with depressive symptoms in males. However, a higher frequency of siblings, having separated parents as well as a more extreme perception of the mother's educational style were consistently associated with depressive symptoms in females.ConclusionThe BDI-II-P showed discriminative power to characterise social–demographic variables related to DD especially in adolescent females.

Joint Factor Analysis

Introduction: Researchers have proposed several theories of depressive rumination. To compare among them, we conducted a joint factor analysis. Methods: An online sample (n = 498) completed four rumination questionnaires and the Beck Depression Inventory. We examined associations between emerging factors and depressive symptoms. Results: Most commonly, people ruminated about solving problems in their lives, followed by the causes or consequences of negative situations. They least commonly ruminated about their symptoms and sadness. Thoughts about symptoms and causes or consequences of negative situations uniquely related to depressive symptoms. There was a circular covariance relation between depressive symptoms, thoughts about causes or consequences, and problem-solving, suggesting that symptoms are regulated by a negative feedback loop involving problem-solving. This feedback was not present unless models included thoughts about causes or consequences, suggesting that these thoughts benefit problem-solving. Discussion: Depressive rumination may be a dynamic process involving various thoughts, with different combinations of thoughts having different consequences for depression.

The objective of current study is to explore prevalence of depression and procrastination among general population who never visited any hospital or any other place for management of their sadistic life and to compare level of depression among clinically diagnosed depressive patients and general population of Punjab. It was core objective of study to explore whether procrastination is the cause of depression and for this purpose relationship between depression and procrastination is made. The sample N=240 comprised of 120 depressive individuals (60=male, 60=female) and 120 individual from general population (60=male and 60=female) living in Lahore, Multan and Faisalabad cities were selected through Purposive and snow ball sampling technique from different hospitals and residential areas. Beck depression inventory (BDI) by Aaron.T.Beck, (1971) and procrastination scale by Tuck man, (1991) were used as tools of the study. It was found out that depression is positively correlated with procrastination. Level of depression is high among married as compared to unmarried and Level of depression is high in males as compared to females. The level of procrastination is less in females as compared to males. Level of procrastination is low among unmarried as compared to married.

The Impact

AbstractDecades of research have investigated the impact of clinical depression on memory, which has revealed biases and in some cases impairments. However, little is understood about the effects of sub-clinical symptoms of depression on memory performance in the general population. Here we report the effects of symptoms of depression on memory problems in a large population-derived cohort (N = 2544), 87% of whom reported at least one symptom of depression. Specifically, we investigate the impact of depressive symptoms on subjective memory complaints, objective memory performance on a standard neuropsychological task and, in a subsample (n = 288), objective memory in affective contexts. There was a dissociation between subjective and objective memory performance, with depressive symptoms showing a robust relationship with self-reports of memory complaints, even after adjusting for age, gender, general cognitive ability and symptoms of anxiety, but not with performance on the standardised measure of verbal memory. Contrary to our expectations, hippocampal volume (assessed in a subsample, n = 592) did not account for significant variance in subjective memory, objective memory or depressive symptoms. Nonetheless, depressive symptoms were related to poorer memory for pictures presented in negative contexts, even after adjusting for memory for pictures in neutral contexts. Thus the symptoms of depression, associated with subjective memory complaints, appear better assessed by memory performance in affective contexts, rather than standardised memory measures. We discuss the implications of these findings for understanding the impact of depressive symptoms on memory functioning in the general population.
