    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; 2210
    Emotion 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.

    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; 2210
    Experiential 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.

    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/A
    Introduction 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.

    the 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.

    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/A
    Substance 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.

    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/A
    Objective 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.
