Aim and Background: How to allocate resources during development and its underlying motives provide developmental psychologists with understanding about fairness development. By age 4, children's social understanding of self and others is increased. This allows children to decide how to allocating resources towards others. As child develops considering fairness or self-interest concerns matters during allocating resources. This study aimed to examine resource allocation development in 4-6-year-old children in advantageous inequality and disadvantageous inequality conditions.

Methods and Materials: This was a correlational study with the population of all 4-6-year-olds from kindergartens in 4 region of Tehran in years 1395-1396. One hundred and two participants aged 4 (n=34, 17 girls), 5 (n=36, 18 girls) and 6 (n=32, 16 girls) were selected through a clustered sampling. Participants were asked to distribute resources in with cost-advantageous/disadvantageous and without cost-advantageous conditions.

Findings: Results showed that children more allocated resources in with cost disadvantageous condition as compared to other conditions (p<0.05). Across age groups, 4-year-old children significantly shared more resources in disadvantageous condition (p<0.05). 6-year-old girls allocated more resources when compared to boys.

Conclusions: Our findings suggest that self-interest seems to be the main motives in allocating resource of 4-6-year-old children in advantageous and disadvantageous conditions. In addition, during 4-6-years of old children do not use fairness consideration in their decisions about resources.

Aim and Background: Obsessive-compulsive disorder affects all aspects of the lives of children and these effects are less considered in the health and clinical system, so the aim of this study was to determine the effectiveness of acceptance and commitment therapy on the severity of symptoms and Function of children with obsessive-compulsive disorder.
Methods and Materials: The present study was a quasi-experimental study with pre-test and post-test with 3-month follow-up and control group. The statistical population of the study included all children with obsessive-compulsive disorder aged 8 to 12 years in Esfahan in 2019, along with their mothers at the time of the study, of which 20 children with their parents, after an authentic psychiatrist or psychologist diagnosed them with obsessive-compulsive disorder and they obtained at least a score of 14 on the Children's Yale-Brown OCD Scale, were selected based on Purposive sampling method and randomly assigned into the experimental and control groups. The experimental group received acceptance and commitment therapy treatment for 10 sessions of individual, but the control group did not receive any intervention. Instruments used in the study included Children's Yale-Brown OCD Scale, Children's Global Assessment Scale and Child Obsessive Compulsive Impact Scale – Revised. To analyze the findings, inferential statistics methods of analysis of repeated measures were used.
Findings: Comparison of experimental group with control group showed that the symptoms of obsessive-compulsive disorder were significantly reduced in the experimental group compared to the control group and the improvement of children's overall function in the post-test and follow-up stages was confirmed (p≤.0.05). so that 71% and 63% of the changes in overall functioning and Total score of symptom severity are affected by acceptance and commitment therapy, respectively. But the effect of acceptance and commitment therapy on family and social functioning was not significant (P≥0.05).
Conclusions: Acceptance and commitment therapy is effective in reducing symptoms and improving overall function in children with obsessive-compulsive disorder.

Aim and Background: Research has increasingly shown a relation between childhood maltreatment and the dysregulated behaviors observed in individuals, yet the mediating factors in this relationship have received little attention. Thus, the primary aim of this study is to explore the role of cognitive processes as mediators in the relationship between childhood maltreatment and the dysregulated behaviors of individuals with bipolar disorder.
Methods and Materials: This study employed a descriptive and correlational research design. The statistical population consisted of all individuals with bipolar disorder who were hospitalized at Razi Psychiatric Hospital during the years 2023-2024. A total of two hundred individuals were selected for the research sample using convenience sampling. Data collection tools included the following: the Binge Eating Severity Scale (Gormally et al., 1982), the Deliberate Self-Harm Inventory (Gratz, 2001), the Alcohol Use Disorders Identification Test (Saunders et al., 1989), the Childhood Trauma Questionnaire (CTQ), the Cognitive Abilities Questionnaire (Nejati, 2013), the Difficulties in Emotion Regulation Scale- Short Form (Kaufman et al., 2016), the Acceptance and Action Questionnaire (Bond et al., 2011), and the Levels of Self-Criticism Scale (Thompson & Zuroff, 2004). Data analysis was conducted using SPSS and LISREL software, employing Pearson correlation and structural equation modeling techniques.
Findings: The study's results indicated that cognitive processes—including cognitive ability, self-criticism, experiential avoidance, and difficulties in emotion regulation—play a mediating role in the relationship between childhood maltreatment and dysregulated behaviors, such as alcohol consumption, binge eating, and non-suicidal self-injury, in individuals with bipolar disorder. The statistical fit of the model was strong, with the following indices: CFI= 0.96, NNFI= 0.95, IFI= 0.96, GFI= 0.92, and RMSEA= 0.072.
Conclusions: People with bipolar disorder who experienced childhood maltreatment often exhibit dysregulated behaviors due to cognitive processes. Therefore, clinical interventions focusing on cognitive processes are essential in preventing maladaptive behaviors in this population.
