Cognitive reactivity (CR) to the experimental induction of sad mood has been found to predict relapse in recovered depressed patients. The Leiden Index of Depression Sensitivity Revised (LEIDS-R) is a self-report measure of CR. The aim of the present study was to establish the validity and reliability of the Persian version of the LEIDS-R. The participants were recovered depressed and non-depressed Iranian individuals (n = 833). The analyses included content validation, factor analysis, construct validity, and reliability testing. Preliminary construct validation analysis confirmed that factor analysis was appropriate for the Persian version of the LEIDS-R. Factor analysis displayed similar factor loadings to the original English version. The total internal consistency of the translated version, which was assessed using Cronbach's alpha coefficient, was equal to 0.90. The test-retest reliability of the total score was equal to that of the test-retest conducted after a two-week interval at 0.94. Content validity, face validity, and construct validity, as well as reliability analysis were all found to be satisfactory for the Persian version of the LEIDS-R. The Persian version of the LEIDS-R appears to be valid and reliable for use in future studies, and has properties comparable to the original version and to that obtained in previous studies.

INTRODUCTION AND OBJECTIVES: Problematic internet use (PIU) has become public health concern, particularly among adolescents and emerging adults. There is growing interest concerning the potential impacts of early maladaptive schemas (EMSs) on PIU and its most severe manifestation internet addiction (IA). However, a deeper understanding of these relationships is needed regarding of effects of schemas on IA. The purpose of the present study was to explore the role of EMSs among adults.
METHODS: The sample comprised 714 Iranian participants who completed a self-report survey comprising sociodemographic variables, the Internet Addiction Test (IAT), and the Young Schema Questionnaire-Short Form (YSQ-SF). The data were analysed using partial least squares structural equation modelling (PLS-SEM).
RESULTS: Findings indicated that there was a positive and significant relationship between EMS domains and IA. The results confirmed that disconnection/rejection schema domains and impaired autonomy/performance schema domains were significantly related with IA. The results of the analysis of convergent validity and discriminant validity were acceptable among the nine reflective constructs.
CONCLUSION: Findings of the present study indicated that existence of underlying EMSs may be a vulnerability factor for developing IA and adds to the growing body of cyberpsychology literature that has examined the relationships between the EMSs and IA.

Psychological distress (including depression and anxiety) is common in the first years of cancer diagnosis but can differ by country and region. The aim of the present paper was to review the prevalence of psychological distress among cancer patients in the Southeast Asia (SEA) region. A systematic literature search was carried out using several databases (i.e., PubMed, PsychARTICLES, Embase, CINAHI, Web of Sciences, Plus, Scopus, and AHMED). Papers originally published in English language were taken into consideration if they (i) were published from 2010 to 2021 and (ii) reported the prevalence of psychological distress among patients with different types of cancer. A total of 23 studies met the inclusion criteria. The most frequently employed psychometric instrument for anxiety and depression screening was the Hospital Anxiety and Depression Scale (HADS). The prevalence of anxiety (ranging from 7% to 88%) was wider than that of depression (ranging from 3% to 65.5%) among patients with different types of cancer and living in various countries in the SEA region. The overall prevalence rate of psychological distress among cancer patients from the SEA region was not fundamentally very different from that of general populations. These findings provide useful information for health professionals and cancer patients to understand the negative role of psychological distress in quality of life and health. The research findings demonstrate the importance of counselling for psychological distress among cancer patients as means of effectively resolving their psychological problems and ultimately improving the quality of oncology medical care. Clinical recommendations for cancer management should incorporate the early identification of (and therapy for) psychological distress, as well as their monitoring during treatment.
