Moderating effect of self-esteem between perfectionism and avoidant restrictive food intake disorder among Lebanese adults

BACKGROUND

Avoidant Restrictive Food Intake Disorder (ARFID) is a new diagnosis added to the DSM-5 characterized by pathological eating habits without body image disturbances. Previous findings demonstrated a general association between high levels of perfectionism and low levels of self-esteem in association with general eating disorders. However, research is scant when it comes to ARFID specifically. Subsequently, although self-esteem is seen to moderate the association between perfectionism and general eating disorders, this research study aims to explore the same moderation but with ARFID specifically.

METHODS

For this study, 515 Lebanese adults from the general Lebanese population were recruited from all over Lebanon, 60.1% of which were females. The Arabic version of the Big Three Perfectionism Scale- Short Form (BTPS-SF) was used to measure self-critical, rigid and narcissistic perfectionism; the Avoidant/Restrictive Food Intake Disorder screen (NIAS) was used to score the ARFID variable; the Arabic-Single Item Self-Esteem (A-SISE) was the scale used to measure self-esteem.

RESULTS

Across the different perfectionism types, self-esteem was seen to moderate the association between narcissistic perfectionism and ARFID (Beta = - 0.22; p =.006). At low (Beta = 0.77; p <.001), moderate (Beta = 0.56; p <.001) and high (Beta = 0.36; p =.001) levels of self-esteem, higher narcissistic perfectionism was significantly associated with higher ARFID scores.

CONCLUSION

This study brought to light some crucial clinical implications that highlight the need for interventions that help in the enhancement of self-esteem in patients with high perfectionism and ARFID. This study suggests that clinicians and healthcare professionals should focus more on risk factors influencing the development and maintenance of ARFID-like symptoms.

Psychometric properties of an Arabic translation of the meaning in life scale in a sample of young adults

BACKGROUND

Young adults are in a constant phase of realizing their meaning in life while being in a constant pursuit of meaning. Meaning in life is a subjective, personal construct related to the perception of one's own life. Considering that there are no measures that study this construct within the Arab context, this study aimed to examine the psychometric properties of an Arabic translation of the Meaning in Life Questionnaire (MLQ) in the Lebanese context with a sample of young adults.

METHODS

A sample of 684 Lebanese young adults was recruited for this study, having a mean age of 21.74 years, 65.6% of which were females. Through an online questionnaire, participants were requested to complete the Meaning in Life Questionnaire (MLQ), Depression, Anxiety and Stress Scale (DASS-8) and the Oviedo Grit Scale (EGO).

RESULTS

CFA indicated that fit of the original bi-dimensional model of MLQ scores was inadequate. Items 9 and 10 cross-loaded to both MLQ factors. After removal of those 2 items, the final model displayed good fit indices. Reliability was good for the Search (ω = 0.89 / α = 0.89) and Presence (ω = 0.88 / α = 0.87) subscales. Additionally, across three levels of gender invariance (Configural, Metric and Scalar), no significant gender-based distinctions were observed in the MLQ scores. The Search subscale was significantly and positively associated with higher GRIT but not psychological distress, whereas the Presence subscale was significantly associated with higher GRIT and lower psychological distress.

CONCLUSION

The results of this study contribute to the psychometric reliability and validity of the Arabic version of the MLQ and makes it available for dissemination among young adults within the Arab context. This allows for the implementation of new research that target construct of meaning in life, allowing for the accessibility of interventions that aim to foster the presence of and search for meaning in the lives of young adults within the Arab nations.

Psychometric properties of the Arabic version of the intolerance of uncertainty scale: a multinational study

INTRODUCTION

It is common for people to experience anxiety when contemplating their unknown future. Studies have shown that those who tend to worry more about their future are more likely to be intolerant of uncertainty. In order to study the way people from the Middle East tackle uncertainty, a valid and reliable scale is needed. In this context, the present study aimed to examine the psychometric properties of the Arabic version of the 12-item Intolerance of Uncertainty Scale (IUS-12) in a community sample of native Arabic-speaking participants from Lebanon, Egypt, and Kuwait.

METHODS

A sample of 2038 university students answered the survey, with a mean age of 22.30 ± 4.15 years and 77.5% females. A Google Form link was dissipated among participants that included some demographic questions, the IUS-12 and the Depression, Anxiety and Stress Scale (DASS-8).

RESULTS

Following the confirmatory factor analysis (CFA), a bi-dimensional model of the Arabic version of the IUS-12 was found. The scale showed an excellent internal reliability for the prospective anxiety (ω = 0.85 / α = 0.85) and inhibitory anxiety (ω = 0.87 / α = 0.87). Additionally, the results illustrated configural, metric, and scalar invariance across genders and countries. Furthermore, Egypt and Lebanon were seen to have statistically significant higher levels of inhibitory anxiety compared to Kuwait, while only Egypt showed statistically significant higher prospective anxiety compared to Kuwait. Finally, higher psychological distress was significantly and positively associated with higher prospective and inhibitory anxiety.

CONCLUSION

The results of this study provide support for the psychometric reliability and validity of the Arabic version of the IUS-12, allowing for its generalizability and suitability for use among individuals from different Arabic-speaking nations.

Evaluation of the analgesic effects of diclofenac as a premedication drug in dogs undergoing ovariohysterectomy

Pre-emptive analgesia consists of administering drugs such as opioids and nonsteroid anti-inflammatory drugs. This study aims to evaluate the intraoperative antinociceptive effects of diclofenac administered alone in premedication or combined with morphine along with its potential influence on recovery of dogs undergoing ovariohysterectomy. A total of 34 dogs (ASA I or II) admitted for ovariohysterectomy were randomly allocated into three groups according to the drugs given in premedication: Diclofenac (D) (n = 11), Morphine (M) (n = 13) and Diclofenac-Morphine (DM) (n = 10) groups. Induction and maintenance of anesthesia were standardized in all dogs. To assess intraoperative nociception, the heart rate (HR) and mean arterial pressure (MAP) were recorded during the surgery and at predefined time points: St (steady-state), Cut (cutaneous incision), P1 (first ovarian manipulation), P2 (second ovarian manipulation) and Cerv (cervical manipulation). The dynamic variation of HR (ΔHR) and MAP (ΔMAP) over 2 min was calculated at each time point. After extubation, early quality of recovery was assessed. Compared to St, a significant increase in HR and MAP at P1, P2 and Cerv was shown in all groups. MAP in the M group was lower at St than in the other groups. The dynamic variation of HR (ΔHR) and MAP (ΔMAP) was significantly less important at P2 and Cerv compared to P1 only in the DM group. Also, a better quality of recovery was shown in the D group compared to the M and DM groups. Diclofenac may be considered a suitable premedication drug and a part of a multimodal anesthetic approach in dogs.

Coping during socio-political uncertainty

Introduction

Well-being of young adults is known to be compromised in times of significant changes, such as economic and political turmoil. This study focuses on university students in Lebanon during one of the most prominent social unrests of its modern history to determine potential understudied protective factors that would predict the youth capacity to strive.

Methods

A sample of 489 university students were asked to fill an online survey including standardized questionnaires of wellbeing (WEMWBS), depression (PHQ-9), anxiety (HAM-A), intolerance of uncertainty (IUS-12), coping (Brief COPE) in addition to demographics and questions about their attitudes and future perspectives.

Results

We found increased rates of mental distress, predominantly in women, with around 80% of the sample being highly intolerant to the uncertainty climate. Results unsurprisingly show that well-being negatively correlated with anxiety, depression and intolerance of uncertainty. Overall, mental distress was found to mediate the relation between uncertainty and wellbeing, and the relation between maladaptive coping and wellbeing. Students who were intolerant of uncertainty and who used maladaptive coping strategies were more likely develop anxiety and depression and subsequently report poorer wellbeing. Conversely, having adaptive strategies was directly linked to higher well-being.

Discussion

In spite of increased distress, some university students managed to preserve their well-being within a climate of severe socio-political uprise. These findings suggest that modifying subjective experience of events and using soft skillset could alleviate young adults' emotional distress in unstable societies.

Validation of the Arabic version of the resilience scale for adolescents (READ)

INTRODUCTION

Adolescents react differently to challenging negative life events. Resilience, a dynamic characteristic of individuals, was studied to be a protective factor against such events. In order to study the resilience among Arabic-speaking adolescent populations, age-appropriate measures that are fully apprehended by younger respondents are needed. In this context, the present study aimed to examine the psychometric properties of an Arabic translation of the Resilience Scale for Adolescents (READ) in a community sample of native Arabic-speaking adolescents aged 13-18 years.

METHODS

A sample of 546 community Arabic-speaking adolescents from Lebanon was recruited (n = 328 females, with a mean age of 15.76 ± 1.65 years). Through an online questionnaire, participants were requested to complete the READ, Depression, Anxiety and Stress Scale (DASS-8) and the 13-item Children's Impact of Event Scale (CRIES-13).

RESULTS

Following the exploratory and confirmatory factor analysis (EFA-to-CFA) strategy, a unidimensional model of the Arabic version of the READ was met after 10 items were removed from the scale, and showed strong internal consistency (Cronbach's alpha of 0.943). Additionally, the one-factor solution of the Arabic version of the READ was identical across male and female adolescents at the three levels of invariance (Configural, Metric and Scalar). Finally, higher resilience scores were significantly correlated with lower levels of psychopathology, namely depression, anxiety, stress and PTSD, thus attesting to the concurrent validity of the Arabic READ.

CONCLUSION

Findings lend support to the psychometric reliability and validity of the Arabic version of the READ, and therefore its suitability for use among Arabic-speaking adolescents. The availability of this tool facilitates the implementation of interventions that foster resilience, especially in adolescents who have faced a number of negative life events.

Intraparenchymal injection of bone marrow mesenchymal stem cells reduces kidney fibrosis after ischemia-reperfusion in cyclosporine-immunosuppressed rats

Ischemia-reperfusion and immunosuppressive therapy are a major cause of progressive renal failure after kidney transplantation. Recent studies have shown that administration of bone marrow mesenchymal stem cells (MSCs) improves kidney functional recovery in the acute phase of post ischemia-reperfusion injury. In the present study, we used an original model of renal ischemia-reperfusion in immunosuppressed rats (NIRC) to investigate the effects of bone marrow MSCs on progression of chronic renal failure and the mechanisms potentially involved. Left renal ischemia-reperfusion (IR) was induced in unilateral nephrectomized Lewis rats. After IR, rats were treated daily with cyclosporine (10 mg/kg SC) for 28 days. MSCs were injected into the kidney at day 7 after IR. At day 28 after IR, kidneys were removed for histomorphological, biochemical, and gene expression analysis. The effect of conditioned media from MSCs on epithelial-mesenchymal transition was studied in vitro on HK2 cells. Our results show that, as compared to untreated NIRC rats, rats treated by intrarenal injection of MSCs 7 days after IR displayed improvement in renal function, reduction of interstitial fibrosis, and decrease in chronic tubule injury. These effects were associated with a decrease in interstitial α-SMA accumulation and MMP2 activity, markers of fibroblast/fibroblast-like cell activation, and renal remodeling, respectively. Finally, experiments in vitro showed that MSC-conditioned medium prevented epithelial-mesenchymal transition induced by TGF-β in HK2 cells. In conclusion, our results show that, in immunosuppressed animals, a single intrarenal administration of MSCs reduced renal fibrosis and promoted the recovery of renal function.
