Nursing is one of the important professions for public health. The purpose of the present research was to investigate Morningness- Eveningness in relation to sleep quality and occupational motivation in nurses working in health centers of Ardabil.
A descriptive-correlational design was used to conduct the study. The statistical population comprised of nurses working in the hospitals of Ardabil in 2015, in which using the cluster sampling method, 198 nurses working in Ardabil’s hospitals were selected to the study. In order to collect data, the questionnaires of Pittsburg's sleep quality, Morningness-Eveningness (CSM) and the scale of occupational motivation were used. The multi-variant variance analysis and pursued test were used to analyze the data.
Data analysis identified Morningness-Eveningness of the 198 nurses participated in the study as follows: morning-type (20%), evening-type (14%) and 66% of the subjects had a combination of morning-type and evening-type (mixed-type) of work shifts. By comparing three groups of evening-type, mixed-type and morning-type was found that evening shift nurses have a lower sleep quality. Moreover, evening work shift nurses had a lower professional motivation in comparing with nurses who were working in morning and rotational shifts. Also, significant correlations were found between the Morningness with sleep quality and occupational motivation of the participants.
The results show that sleep problems is a major problem among nurses. This problem is greater among the nurses working in evening work shifts which can decrease the professional motivation of nurses. Attention to the circadian rhythms of individuals may help to reduce these problems.

This study aimed to investigate the relationship between morningness, eating behaviors, positive and negative affect and eating chocolate and to evaluate these variables with regard to eating breakfast.
The study design was correlational. 125 undergraduate students of Faculty of Psychology and Education of University of Tehran completed Dutch Eating Behavior Questionnaire, Positive and Negative Affect Scale and Composite Scale of Morningness. 80 of these subjects then participated in a chocolate sham-palatability test. The number of chocolates participants tasted was considered as an objective measure of eating behavior.
Morningness had positive relationship with positive affect (r=0.35, p The correlation between the number of chocolates consumed and emotional eating is an important finding of the study introducing the test for objective measurement of emotional eating phenomenon. In addition, morningness was correlated with positive affect and external eating that is in accordance to previous research.

Improvement of sleep quality is one of the major issues of human life that can help people maintain their energy resources and has beneficial effects on many behaviors. The aim of this study was to determine the sleep quality and its associated factors among students of Razi School of Nursing and Midwifery، Kerman، Iran. A total of 349 students were included in this cross-sectional study. The demographic، PSQI، POMS، MES and SUDS questionnaires were used for data gathering. The obtained data were analyzed by descriptive statistics، X2، ANOVA and multivariate logistic regression. Results of this study showed 79. 4% of students were females with mean (±SD) age of 22. 69 (± 5. 24) years. Most students were single (75. 1%). 71% of students had poor sleep quality. The results of multivariate regression showed a significant relationship between unsuitable sleep quality and the habit of listening to music before bedtime and negative mood states (anxiety، depression، anger، fatigue and confusion). These results demonstrated a high prevalance of poor sleep quality in nursing and midwifery students. It seems that implementation of strategies for reducing the associated factors is very important. Also، more studies are recommended to find other related factors.

The aim of the present study was to examine the personality variables of morning-type, rigidity, neuroticism, extroversion, openness, agreeableness and conscientiousness as predictors of shift work tolerance in an industrial company in Ahvaz. The sample consisted of 245 shift workers which were selected by the use of stratified random sampling. At first the participants divided into two groups (low tolerance shift workers versus high tolerance shift workers) by using Survey of Shift workers. Then each group of participant s was evaluated by using NEO questionnaire. In order to analyze the data, the discriminate analysis and in the validation stage, the Pearson's Correlation Coefficient were applied. Findings, confirm the hypothesis of this study. On the other hand, findings revealed that tolerance of shift work can be predicted from Personality variables. The results of this study showed the importance of morning-type, neuroticism, and rigidity as predictors of shift work tolerance. Therefore, in order to select people for shift work systems we recommend to rely on these variables.
