Aim: The purpose of present study is testing the model of structural equation modeling for explanation of academic achievement based on student's goal orientation and subjective well-being and parent's subjective well-being and goal orientation in Third year high school students.
Sample and Sample size: 441 females’ students and their parents selected by cluster sampling in this correlation study.
Instruments: Students filled the Positive and Negative Affect Schedule, subscale of perceptions of parent's goal orientation and their parents filled the Positive and Negative Affect Schedule Life satisfaction scale. Obtained Data were analyzed by structural equation modeling through Amos software.
The results of structural equation modeling show that hypothesized models have an acceptable fit to the data. Results indicate that student's goal orientation and subjective well-being mediate the relationship between academic achievement and parent's goal orientation and subjective well-being
in sum, these results indicate a part of difference in academic achievement accounted by student's subjective well-being and goal orientation and their parent's subjective well-being and goal orientation.

The purpose of this study was to examine the relationship between positive affect, negative affect, rumination and depression, and to explore the mediating role of rumination between positive and negative affect and depression.
A cross-sectional study was conducted involving 249 students, selected by convenience sampling method. All the participants completed positive and negative affect schedule, The Ruminative Response Scale and Beck depression inventory. Statistical analysis was done using the R 3.4.2 software.
Positive affect exhibited a significant negative relationship with rumination and depression. Also, there was a significant positive relationship between negative affect and rumination and depression. In addition, results showed that rumination partially mediated the relationship of positive and negative affect with depression.
Considering the results, it can be concluded that rumination, directly and indirectly, mediates between positive and negative affect and depression, and can predict depression. Based on the increasing positive affect and reducing negative affect, therapeutic interventions can be provided that would decrease rumination, and thereby prevent or control depression

The purpose of the present study was to examine the moderating role of positive and negative affects on the relationship between attachment styles and marital problems. Participnts were 160 married individuals (36 men, 124 women). Participants completed the Adult Attachment Inventory (AAI), The Golombok-Rust Inventory of Marital State Questionnaire (GRIMS), and Positive and Negative Affect Schedule (PANAS). The results showed a significant positive correlation between insecure attachment styles (avoidance and ambivalence) and negative affect with marital problems. Secure attachment style and positive affect showed a significant negative correlation with marital problems. Analysis of the data revealed that the relationship between insecure attachment styles and marital problems was moderated by positive affects. Increasing levels of positive affect was accompanied with weaker relationship between insecure attachment styles and marital problems. Negative affects showed no significant role in the relationship between attachment styles and marital problems. It can be concluded that attachment styles as well as positive and negative affects can predict marital problems.

the mediating effects of positive and negative affects on the relationship between dimensions of perfectionism (self-ori- ented, other-oriented, and socially prescribed) with physical health in a sample of general population were studied. One hundred and thirty one women and 103 men volunteered for this study. Participants were asked to complete the Tehran Multidimensional Perfectionism Scale (Besharat, 2007), Positive and Negative Affect Schedule (Watson, Clarke, & Tellegen, 1988), and the Physical Health Inventory (Molnar, Reker, Culp, Sadava, & DcCourville, 2006). Positive and negative affects mediated the relationship between self-oriented and other-oriented perfectionism with physical health in opposite directions. Positive and negative affects did not show a significant mediation effect on the relationship between so- cially prescribed per- fectionism and physical health. It was concluded that the mediation effect of negative affects (R2 = 0.56) was greater than the mediation effect of positive affects (R2=0.44) in the relationship between dimensions of perfectionism and physical health.

The aim of this study was to investigate the relationship of social anxiety and positive and negative affects with science persuasion in registrar. This correlation study enrolled 230 registrars consisting of 115 man and 115 women who lived in Ardebil city. To collect the data, Social Interaction Anxiety, Scale Positive and Negative Affect Schedule, persuasion- IQ questionnaire were employed. The data were analyzed using Pearson correlation coefficient and step-by-step regression. Results showed that there is a negative correlation between social anxiety and negative affect with science persuasion.However, there is a positive correlation between positive and negative affects with science persuasion. Furthermore, we showed that positive affect explain roughly 8 percent science persuasion of variance.

The purpose of this study was to investigate the mediating role of positive and negative affect in the relationship between meaning in life and mental health. The sample consisted of 337 students (153 males and 184 females) from University of Tehran at three levels: BA, MA and PHD. Participants are chosen by available sampling. The students answered the Crumbaugh Maholick (1964) Meaning of Life Questionnaire, Veit and Ware (1983) Mental Health Inventory and Watson et al (1988) Positive and Negative Affect Schedule. For analyzing data, we used some indexes such as Frequency, Percent, Standard deviation, Pearson correlation test and for proving the mediating role, we used Pathway analysis. The results showed a significant positive and negative relationship between meaning in life and psychological well-being as well as psychological distress. The Pathway analysis showed that positive and negative affect has mediating role in the relationship between meaning in life and mental health. According to the result, it can be concluded that, attention to meaning in life and improve it in students life lead to increasing positive affect and as a result can influence mental health and decrease expression of negative affect and psychological distress level.

To compare resilience, positive/negative effect, and psychological vulnerability between fertile and infertile men. The research sample consisted of 40 fertile and 40 infertile men who were selected among men who presented to an infertility clinic. To collect data, Connor–Davidson Resilience Scale, Positive/Negative Affect Schedule, and Brief Symptoms Inventory were used. The MANOVA results showed that infertile men had higher mean (SD) score for negative affect (46.15±8.31 vs. 23.10±8.50) and psychological vulnerability (37.90±12.39 vs. 23.30±6.40) than fertile men (P= 0.001); while infertile men had lower resilience (59.35±14.25 vs. 82.17±13.03) and positive affect (43.01±10.46 vs. 61.85±8.14) than fertile men (P= 0.001).The results of multiple regressions showed that resilience and negative affect had the highest significant contribution in prediction of psychological vulnerability in the infertile. Resilience and negative effects are the best predicators for mental vulnerability of infertile men. These factors may be addressed in future studies in infertile men.

The aim of the present study was to investigate the relationship among alexithymia, responsibility attitude, positive and negative affect, and suicidal ideation in people with obsessive tendencies.
Material and The study sample was comprised of 400 students from Tabriz University from whom 151 students with an obsession score higher than the cut-off point were selected randomly as people with obsession tendency. Toronto Alexithymia Scale (TAS-20), responsibility attitude scale (RAS), PANAS Positive and Negative Affect Schedule, Yale-Brown Obsessive-Compulsive Scale and Beck Scale for Suicidal Ideation (BSSI) were used to collect the data. The data were analyzed using Pearson product-moment correlation method and hierarchical regression.
The hierarchical regression results showed that controlling demographic variables, alexithymia variable as overall, difficulty identifying feelings subscale, difficulty describing feelings subscale and negative affect can predict suicide. Responsibility and positive affect variables and externally-oriented thinking in alexithymia could not predict the dependent variable.
Based on these findings, we can conclude that difficulty identifying feelings, difficulty describing feelings and negative affect are the main determinants for suicide in people with obsessive tendencies.

aim of this study was to examine factorial invariance of the 20-item Positive and Negative Affect Schedule-Farsi version (PANAS) among male and female university students. A total of 371 undergraduate students (183 males and 188 females) at Shahid Beheshti University completed the Farsi version of the PANAS. First، two-factor model consisted on positive and negative affect were applied to the total sample. Then، single group analysis showed an acceptable two-factor measurement model consisting of positive and negative affect for both male and female groups. Further، based on the one-factor model، results from multi-sample analysis revealed that the Farsi version of the PANAS has the property of sound factorial invariance across sexes، including invariance of measurement residuals، structural covariances and regression measurements. These findings emphasizing the group invariance of factorial structure of PANAS، indicate that PANAS measures a similar construct in these subsamples. The results revealed that the two factors of positive and negative affects in PANAS were perceived in the same manner across students in the two sex groups.

The present study aimed to predict students’ psychological well-being based on forgiveness and meaning in life by considering the mediating role of positive and negative affects. It was conducted with a correlational method. Therefore, 377 students from the University of Kashan, Iran, were selected through multi-stage sampling and filled out Steger Meaning in life questionnaire, Ehteshamzadeh et al. Interpersonal forgiveness scale, Positive & Negative affect Schedule (PANAS) and Ryff psychological well-being Questionnaire. Data were analyzed using Structural Equation Modeling in Amos (version 22). The results showed that forgiveness and meaning in life could significantly predict students’ psychological well-being; moreover, positive and negative affect have a mediating role in the relationship between forgiveness, and meaning in life with psychological well-being. Considering the modeling indices, it could be argued that the proposed model had a good fitness, and it had good agreement with the empirical data. In this model, all regression weights were statistically significant, and predictor variables could explain .77 of the variance of psychological well-being. The implication is that positive and negative affects could be increased, leading to students’ psychological well-being, by enhancing students’ forgiveness and meaning in life.
