1 Investigating the Relationship Between Perceived Stress and Addiction Readiness Among Students of Zahedan University of Medical Sciences, 2023 - 2024 https://brieflands.com/journals/ijhrba/articles/170293 10.5812/ijhrba-170293 1 Background :University students face substantial academic and psychosocial pressures that may increase their vulnerability to risky behaviors. Objectives :This study examined the association between perceived stress and addiction readiness among students at Zahedan University of Medical Sciences (ZaUMS) during the 2023 - 2024 academic year. Methods :In this cross-sectional study, 612 students completed the 14-item Perceived Stress Scale (PSS-14) and the Iranian Addiction Potential Scale (IAPS). Sampling was conducted using a stratified proportional framework across six faculties. Students were recruited from classrooms, dormitories, and clinical training settings until the recruitment quota for each faculty was reached. Questionnaires with extensive missing responses were excluded, and limited item-level missingness was handled using prespecified prorated scoring. Pearson correlations (overall and sex-stratified) and multivariable linear regression with HC3 robust standard errors were used to assess the association between stress and addiction readiness after adjustment for sociodemographic factors and self-reported substance use. Analyses were conducted using IBM SPSS Statistics version 26. Results :The mean age was 21.46 ± 1.44 years, and 73.5% of participants were male. The mean PSS-14 and IAPS scores were 25.34 ± 5.58 and 55.04 ± 34.93, respectively. Perceived stress was positively correlated with addiction readiness (r = 0.38, P < 0.001), with a stronger correlation among females (r = 0.58) than among males (r = 0.26). In adjusted models, perceived stress remained independently associated with higher IAPS scores (fully adjusted model: b = 2.20 per 1-point increase in PSS score; P < 0.001). In the sex-interaction model, the perceived stress × male interaction coefficient was negative and statistically significant (b = -2.32; 95% CI, -3.14 to -1.51; P < 0.001). Conclusions :Higher perceived stress was significantly associated with greater addiction readiness among medical sciences students. Given the cross-sectional design, the findings should be interpreted as associations rather than causal effects. Longitudinal and interventional studies are warranted to determine whether stress-focused interventions can reduce addiction-related vulnerability in university settings. 1 8 Majid Dastras Community Nursing Research Center, Department of Nursing, Zahedan University of Medical Sciences, Zahedan, Iran Iran majid.dastras.fm@gmail.com Fatemeh Rigi Community Nursing Research Center, Zahedan University of Medical Sciences, Zahedan, Iran Iran f.rigi2011@gmail.com Alireza Salar Community Nursing Research Center, Zahedan University of Medical Sciences, Zahedan, Iran Iran salar293@gmail.com Nazanin Yousefian Miandoab Community Nursing Research Center, Zahedan University of Medical Sciences, Zahedan, Iran Iran n.yoosefian@yahoo.com Zahra Pournamdar Community Nursing Research Center, Zahedan University of Medical Sciences, Zahedan, Iran Iran zahrapournamdar@yahoo.com Mehdi Rezvaniamin Community Nursing Research Center, Zahedan University of Medical Sciences, Zahedan, Iran Iran mehdi.rezvaniamin@gmail.com No Keyword 1.pdf [0]Cohen S, Kamarck T, Mermelstein R.A global measure of perceived stress.

1 A Comparative Analysis of Anxiety Sensitivity and Distress Tolerance Across Age Groups in Cigarette-Dependent Men https://brieflands.com/journals/ijhrba/articles/167659 10.5812/ijhrba-167659 1 Background :Although the association between cigarette smoking and mental health is well established, the specific theoretical and empirical links among cigarette dependence, anxiety sensitivity (AS), and distress tolerance (DT) remain poorly delineated across developmental stages. Objectives :This study investigated the relationships among cigarette smoking, anxiety sensitivity, and distress tolerance among nicotine-dependent male smokers across different age groups. Methods :In this comparative cross-sectional study, 278 male smokers were recruited through convenience sampling in Tehran, Iran, during the summer of 2024. Participants completed the Distress Tolerance Scale (DTS) and the Anxiety Sensitivity Index-Revised (ASI-R). Data were analyzed using descriptive statistics, multivariate analysis of covariance (MANCOVA), and Bonferroni post hoc comparisons in SPSS version 26. Results :MANCOVA revealed significant between-group differences in anxiety sensitivity (F = 19.234, P < 0.001) and distress tolerance (F = 28.189, P < 0.001). Smoking intensity and duration were significant covariates of anxiety sensitivity (F = 32.070, P < 0.001; F = 7.268, P = 0.007) and distress tolerance (F = 40.894, P < 0.001; F = 7.266, P = 0.007), respectively. Bonferroni post hoc comparisons indicated significant age-group differences in anxiety sensitivity and distress tolerance, with most effect sizes ranging from medium to large (P < 0.05). Conclusions :These findings reveal significant age-related differences in anxiety sensitivity and distress tolerance, indicating that psychological assessments and smoking cessation interventions for nicotine-dependent men should be tailored to specific age groups. Further research is needed to corroborate these findings and explore the underlying mechanisms. 1 11 Isaac Rahimian-Boogar Department of Clinical Psychology, Faculty of Psychology and Educational Sciences, Semnan University, Semnan, Iran Iran i_rahimian@semnan.ac.ir Yaser Bodaghi Department of Clinical Psychology, Faculty of Psychology and Educational Sciences, Semnan University, Semnan, Iran Iran yaserbodaghi@semnan.ac.ir No Keyword 2.pdf [0]Jackson SE, Tattan-Birch H, Buss V, Shahab L, Brown J.Trends in daily cigarette consumption among smokers: A population study in England, 2008 - 2023.

1 Understanding Cyberbullying Perpetration Through Childhood Emotional Abuse: The Mediating Roles of Interpersonal Cognitive Distortions and Intolerance of Uncertainty https://brieflands.com/journals/ijhrba/articles/169977 10.5812/ijhrba-169977 1 Background :The increasing use of social media has created a context for a covert and persistent form of aggressive behavior known as cyberbullying perpetration (CP) that may disrupt interpersonal relationships in online spaces. Objectives :This study aimed to examine whether interpersonal cognitive distortions (ICD) and intolerance of uncertainty (IU) mediate the relationship between childhood emotional abuse (CEA) and CP in 375 active Iranian social media users aged 18 - 35 years. Methods :This descriptive correlational study used structural equation modeling (SEM). Data were collected using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), Cyberbullying Perpetration Questionnaire (CPQ), Interpersonal Cognitive Distortions Scale (ICDS), and Intolerance of Uncertainty Scale (IUS), and were analyzed using SEM. Results :The results indicated significant positive associations between CEA and CP (β = 0.300, P < 0.001) and between ICD and CP (β = 0.236, P < 0.001). In contrast, the direct association between IU and CP was not significant (β = -0.088, P = 0.079). CEA was also significantly associated with both ICD (β = 0.449, P < 0.001) and IU (β = 0.377, P < 0.001). The analysis revealed a statistically significant indirect association between CEA and CP through ICD (b = 0.189; 95% CI, 0.088 to 0.321; P = 0.001). In contrast, the indirect association through IU was not significant (b = -0.059; 95% CI, -0.148 to 0.021; P = 0.151), as the confidence interval included zero. Conclusions :These findings underscore the association between cognitive-social mechanisms, including attributional biases, cognitive restructuring, and moral reasoning, and tendencies toward CP, highlighting their potential relevance for the development of preventive interventions. 1 9 Mehrafarin Pirzadeh Department of Psychology, Faculty of Humanities, Tarbiat Modares University, Tehran, Iran Iran mehrafarin.pirzad@yahoo.com Majid Azizi Faculty of Psychology and Educational Sciences, University of Tehran, Tehran, Iran Iran ma.azizi2021@gmail.com Malek Bastami Department of Psychology, Faculty of Humanities, Shahed University, Tehran, Iran Iran bastamimalek@gmail.com No Keyword 3.pdf [0]Kim S, Faith MS.Cyberbullying and ICT use by immigrant youths: A serial multiple-mediator SEM analysis.
