Publication Metadata only Deviation from balanced time perspective and psychological distress: the mediating roles of cognitive fusion and experiential avoidance(Springer, 2022) N/A; Department of Psychology; N/A; N/A; N/A; Department of Psychology; Department of Psychology; Department of International Relations; Abdollahpour Ranjbar, Hamed; Abdulcebbar, Amal; Yılmaz, Ertürk; Kantarcı, Laçin; Altıntaş, Seda; Eskin, Mehmet; Atalay, Ayşe Altan; Resercher; Master Student; Master Student; Master Student; Undergraduate Student; Faculty Member; Faculty Member; Department of Psychology; Department of International Relations; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; N/A; N/A; N/A; N/A; 2210; 205807the study of Time has a long history, dating back to the earliest days of psychological science in the late 1800s. However, the conceptualization of time perspective has led to a better understanding of individuals' healthy and pathological attitudes toward time dimensions. Similarly, Articulated psychological inflexibility components (i.e., Experiential avoidance (Ea) and Cognitive Fusion (CF)) have been found to have solid links with psychopathology, specifically psychological distress. the purpose of this study was to examine the serial mediating functions of Ea and CF in the association between Deviation from Balanced Time Perspective (DBTP) and Depression and anxiety symptoms. also, A reversed model of serial mediation was tested. a total of 203 participants (155 female) aged between 17-73 (M = 28.45, SD = 11.43) completed measures of time perspective, CF, Ea, Anxiety, and depression. CF and Ea functioned as mediators between DBTP and depressioN/Anxiety in the first mediation model. However, in the reversed model, only the mediation effect for depression was observed. these results emphasize the need for tailoring treatments to the requirements of patients struggling with anxiety and depression symptoms, who may be more susceptible to imbalanced time perspectives and time-entrapped cognitive processes.Publication Metadata only Effectiveness of mindful self-compassion therapy on psychopathology symptoms, psychological distress and life expectancy in infertile women treated with in vitro fertilization: a two-arm double-blind parallel randomized controlled trial(BMC, 2024) Sahraian, Kimia; Jahromi, Bahia Namavar; Cheung, Ho Nam; Ciarrochi, Joseph; Asgarabad, Mojtaba Habibi; Abdollahpour Ranjbar, Hamed; Graduate School of Social Sciences and HumanitiesObjectivesInfertility is a prominent problem affecting millions of couples worldwide. Recently, there has been a hightened emphasis on elucidating the subtle linkages between infertility treatment leveraging assisted reproductive technology and the complex realm of psychological challenges, as well as efforts in implementation of psychological interventions.The Mindful Self-Compassion (MSC) program seeks to improve self-compassion, compassion for others, mindfulness, and life satisfaction while reducing depression, anxiety, and stress. In the current study, an MSC intervention was performed on infertile women (IW) undergoing in vitro fertilization (IVF) to assess the effectiveness of this intervention in reducing psychological distress and psychopathological symptoms and enhancing life expectancy.MethodsFifty-seven IW undergoing IVF were randomly allocated to two groups: MSC (n = 29) or treatment as usual (TAU; n = 28). Participants in MSC met once a week for two hours for eight weeks and attended a half-day meditation retreat. The Synder's Hope questionnaire and the Revised 90-Symptom Checklist (SCL-90-R) were used as the primary outcome measures. Data were obtained before the intervention, immediately after the intervention, and two months post-intervention. Repeated measures of ANCOVA and paired t-tests in all assessment points were used to compare the MSC and the TAU groups in outcomes.ResultsIn the MSC group, hopelessness, anger-hostility, anxiety, interpersonal sensitivity difficulties, and depression were significantly reduced compared with the TAU group, and those improvements persisted at the two-month follow-up. Reliable change index revealed that the MSC group's gains were both clinically significant and durable.ConclusionsMSC can facilitate higher life satisfaction and mental well-being for IW undergoing IVF by reducing psychological distress, psychopathological symptoms, and hopelessness. These encouraging findings call for more research into the effectiveness of mindfulness-based therapies in addressing psychological problems among IW undergoing IVF.Publication Metadata only Emotional dysregulation and craving in patients with dubstance use disorder: the mediating role of psychological distress(Springer, 2023) Darharaj, Mohammad; Hekmati, Issa; Mohammad Ghezel Ayagh, Farahnaz; Ahmadi, Ali; Department of Psychology; Eskin, Mehmet; Abdollahpour Ranjbar, Hamed; Faculty Member; PhD Student; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 2210; N/ASubstance use disorders (SUDs) are chronic conditions influenced by various societal, psychological, and physiological factors that considerably impact their course, maintenance, and recovery. Drug craving, as a proximal risk factor, can precipitate relapse and perpetuate substance use. Psychological distress (PD) and difficulties in emotion regulation (DER) are significant distal risk factors that may facilitate craving and subsequent relapse. This study aimed to examine the relationship between DER and craving in patients with SUDs and the extent to which psychological distress mediates this relationship. The Difficulty in Emotion Regulation Scale (DERS-16), the Temptations to Use Drugs Scale (TUD), and the Depression, Anxiety, and Stress Scale (DASS-21) were used. According to the findings, the total DASS-21 scores acted as a mediator between DER and craving. This association was also mediated by the DASS-21 stress and depression subscales. However, anxiety had no significant role in mediating this relationship. Since DER increases the likelihood of craving in patients with SUD, our results underline the significance of providing them with constructive emotion regulation skills. Furthermore, findings suggest that patients with SUD crave drugs to decrease DER-related depression and stress; hence, tailoring therapeutic approaches to address their psychological triggers of craving is critical. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Publication Metadata only Escitalopram and progressive muscle relaxation training are both effective for the treatment of hot flashes in patients with breast cancer: a randomized controlled trial(Taylor and Francis Ltd, 2022) Shirzadi, Maryam; Farshchian, Negin; Nazarpour, Arash; Eskandari, Soudabeh; Kahrari, Fahimeh; Nazari, Somayeh; Hekmati, Issa; Farhang, Sara; N/A; Abdollahpour Ranjbar, Hamed; PhD Student; Graduate School of Social Sciences and Humanities; N/AIntroduction Available treatments for hot flashes in patients with breast cancer are not always tolerable or effective for all patients. Methods Patients diagnosed to have primary breast cancer were randomly allocated to receive 10 mg of escitalopram, placebo, or progressive muscle relaxation therapy. Patients were asked to report the frequency and duration of hot flashes during day and night, at baseline and after ten weeks of treatment, and completed the menopause rating scale. Results Eighty-two patients were randomly assigned to receive escitalopram (n = 26), PMRT (n = 28), and placebo (n = 28). PMRT and escitalopram could effectively decrease number and duration of diurnal and nocturnal HFs in patients with breast cancer, with a better effect observed from escitalopram. They could both decrease the total score of MRS. Conclusion Both escitalopram ad PMRT can reveal nocturnal and diurnal HFs in terms of frequency and duration in patients with breast cancer.Publication Metadata only Examining the psychometric properties of the behavioral emotion regulation questionnaire-Persian version (BERQ-PV) among Iranians(Springer, 2023) Hekmati, Issa; Jobson, Laura; N/A; Department of Psychology; Abdollahpour Ranjbar, Hamed; Eskin, Mehmet; Researcher; Faculty Member; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 2210Emotion regulation has been dichotomized into two related but distinct domains, namely cognitive and behavioral. There has been an emphasis on the development of measures that evaluate these emotion regulation domains separately. Recently the Behavioral Emotion Regulation Questionnaire (BERQ) was developed. The present study aimed to assess the psychometric properties of a Persian version of the BERQ (BERQ-PV) among an Iranian sample. We investigated the dimensionality, reliability, and validity of the BERQ-PV among participants from the general population (n = 556) and clinical patients (n = 92). The confirmatory factor analysis supported the five-factor model. The internal consistency (Cronbach's alpha = .59-.78) and test-retest reliability (r = .63-.82) of the subscales were acceptable. The significant correlations between the BERQ-PV subscales and depression, anxiety, and stress supported concurrent validity, and the correlations with measures of cognitive emotion regulation implied convergent validity. The significant disparity among the clinical and non-clinical sample groups on the BERQ-PV was suggestive of discriminant validity. Findings indicate that the BERQ-PV is a psychometrically sound measure for assessing the behavioral process of emotion regulation.Publication Metadata only Investigating cognitive control and cognitive emotion regulation in Iranian depressed women with suicidal ideation or suicide attempts(Wiley, 2021) Parhoon, Hadi; Mohammadkhani, Shahram; Munawar, Khadeeja; Moradi, AliReza; Jobson, Laura; N/A; Abdollahpour Ranjbar, Hamed; Researcher; Graduate School of Social Sciences and Humanities; N/AObjective This study compared cognitive control (working memory, interference control, perseveration) and cognitive emotion regulation among Iranian women with depression who had attempted suicide, had only suicidal ideation, and healthy controls. Method Participants (N = 75) completed a clinical interview, cognitive control tasks, and the Cognitive Emotion Regulation Questionnaire. Results Those with suicidal ideation or previous attempts had poorer cognitive control and cognitive emotion regulation than controls. Furthermore, those who had attempted suicide had poorer cognitive control and reported greater use of self-blame, rumination, and catastrophizing, and less use of acceptance, than those with suicidal ideation only. There was an indirect effect of cognitive control deficits on suicidality through cognitive emotion regulation (self-blame, acceptance, rumination, catastrophizing). Conclusions Exploring these cognitive deficits and difficulties can assist in further understanding the risk factors for suicidality and improve targeted interventions. This is of particular relevance in Iran where the need for policies and interventions targeting the prevention of suicide has been identified.Publication Metadata only Psychometric properties and measurement invariance of the multidimensional psychological flexibility inventory- persian (MPFI-P): an extensive investigation of long and short versions in community and clinical samples(Elsevier, 2024) Hekmati, Issa; Ciarrochi, Joseph; Laghaei, Marziyeh; Golezani, Hamed Rezaei; Department of Psychology; Abdollahpour Ranjbar, Hamed; Eskin, Mehmet; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and HumanitiesAcceptance and commitment therapy (ACT) is evidence-based, transdiagnostic psychotherapy that seeks to increase values-consistent behavior and advances mental health by promoting psychological flexibility (PF) and diminishing psychological inflexibility (PI). PF implies a person's ability to cope with, accept, and adjust to challenging circumstances, whereas PI denotes the inflexible dominance of psychological responses in steering behavior over selected values and contingencies. The Multidimensional Psychological Flexibility Inventories (MPFI-60-24) have been established to cover all six factors of PF and six factors of PI at once. Still, these measures have yet to be validated in a Persian sample and this study seeks to validate the Persian versions of MPFI. We evaluated long and short versions of the MPFI in a Persian sample of 1270 (83% females, ages 18 through 57), divided into two groups, a healthy community group (n = 886) and a clinical group (n = 391). The MPFIs' psychometric properties, including criterion validity, construct validity, internal consistency, and measurement invariance, were investigated. Confirmatory factor analysis (CFA) revealed that a 12-factor model had a good fit to the data for the long version (CFI = .92) and a very good fit (CFI = .98) for the short version. Regarding higher-order models, two-factor second-order model indices for long-form were adequate (CFI = .92), and for short-form, they were good (CFI = .96). All 12 subscales demonstrated sufficient reliability. Measurement invariance for gender and mental health state was observed, as well as good internal consistency and adequate criterion validity with psychological distress markers (i.e., depression, anxiety, and stress). PI was more strongly related to psychological distress than PF. Persian versions of the MPFI are reliable instruments for indexing PF and PI in both genders as well as in community and clinical samples.Publication Metadata only The experiences and support needs of Turkish individuals bereaved by suicide: an online qualitative investigation(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2024) Department of Psychology; Eskin, Mehmet; Karkın, Ayşe Nur; Eyisoylu, Elif; Şeker, Elvan; Yılmaz, Ertürk; Sevin, Gamze; Kantarcı, Laçin; Gülşen, Yaren; Abdollahpour Ranjbar, Hamed; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and HumanitiesSuicide is a public health issue that impacts an average of six family members and up to 135 community members. Persons bereaved by suicide may feel guilt, stigma, shame, and rejection. In T & uuml;rkiye, suicide survivors may face additional challenges due to Islamic taboos and sanctions placed on suicide. This study explores the experiences and support needs of Turkish suicide survivors through an online survey. Using NVivo software for thematic analysis, we examined responses from 73 participants and identified three predominant themes: (1) the impact of suicide, (2) support experiences and perceptions, and (3) recommendations for appropriate support provision. Each theme contained several subthemes. Our findings indicated a lack of available services and an unmet need for support.Publication Metadata only The moderating role of experiential avoidance on the relationship between cognitive fusion and psychological distress among Iranian students(Springer, 2023) Hekmati, Issa; Drake, Chad E.; Jobson, Laura; N/A; Department of Psychology; Abdollahpour Ranjbar, Hamed; Eskin, Mehmet; PhD Student; Faculty Member; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; 2210Experiential avoidance and cognitive fusion are two transdiagnostic constructs underpinning psychological distress. This study aimed to explore the moderating role of experiential avoidance on the association between cognitive fusion and psychological distress. The sample consisted of 297 college students who were randomly selected by cluster sampling method. Participants completed the Cognitive Fusion Questionnaire, Acceptance and Action Questionnaire, and the Inventory of Depression and Anxiety Symptoms. It was found that experiential avoidance and cognitive fusion accounted for a significant amount of variance in depression (R-2 = .51). Furthermore, experiential avoidance moderated the relationship between cognitive fusion and depression; follow-up analysis showed that experiential avoidance had a buffering effect of cognitive fusion on depression. With regard to anxiety, findings showed experiential avoidance and cognitive fusion accounted for a significant amount of variance in anxiety symptoms (R-2 = .42), but the interaction between experiential avoidance and cognitive fusion was not significant. The findings suggest that experiential avoidance may play a moderating role with regard to the relation of cognitive fusion and depression, but not anxiety.Publication Metadata only The Reynolds Intellectual Assessment Scales: measurement invariance and mean comparison across United States and Iranian children(Springer Nature, 2024) Tabiani Nian, Lida; Mahmoudi, Hojjat; Reynolds, Cecil R.; Dalvand, Sahar; Ebrahimiave, Seyedehmitra; Abdollahpour Ranjbar, Hamed; Graduate School of Social Sciences and HumanitiesObjectiveExploring the influence of culture on neuropsychological testing presents a complex challenge for researchers. Recently, RIAS-2 has garnered interest in cross-cultural studies. However, there remains a gap in understanding how Asian cultures, particularly in the Middle East, affect the outcomes of this test. This study aims to investigate the invariance and comparative performance of Iranian and U.S. children on the RIAS-2, shedding light on this aspect of the puzzle.MethodThe current study conducted a comparative analysis involving Iranian and U.S. children. A total of 178 Iranian children were chosen through cluster sampling from Tehran and completed the Reynolds Intellectual Assessment Scales (RIAS-2) test. The U.S. sample was carefully matched with the Iranian group and made available to the researchers for analysis.FindingsIn this study, we initially examined a single-factor model encompassing all subtests across both groups. However, the SPS subtest was excluded from this model. Subsequently, we employed index scores, revealing that only two indexes, CIX and SPI, maintained invariance across the two cultural groups. Notably, in both models, U.S. participants exhibited higher average scores compared to their Iranian counterparts. Additionally, the ANOVA test, serving as a supplementary measure, yielded nearly identical results regarding the average score discrepancy.ResultsThe findings of this study underscored the suitability of CIX and SPI scores as reliable indicators for cross-cultural investigations. Furthermore, in the following, some cultural factors affecting the difference in IQ scores between the U.S. and Iranian groups were discussed.
