ABSTRACT
Objective: This study was designed to compare object relations and anger control between MS patients and normal individuals. Method : The present study was a cross-sectional case-control study with two groups: the case group (patients with MS) and the control group (normal controls without MS). 80 patients and 80 healthy individuals were selected according to the inclusion and exclusion criteria using a simple random sampling method. The research's data collection tool was a three-part questionnaire consisting of demographic information, the Bell Object Relations and the Reality Testing Inventory (BORRTI) and the State-Trait Anger Expression Inventory 2 (STAXI-2). The data were analyzed by the SPSS software version 26 using descriptive and analytical statistics (stepwise regression). Results: The results showed that in terms of object relations, there was no significant difference between the two groups except in alienation of relations (P = 0.035). The results also showed that in general, there was no statistically significant difference between the anger index of the group of MS patients and the normal controls. However, 12.8% of MS patients were significantly different in state of anger, trait anger and anger control compared to normal individuals. This difference was especially higher in angry temperament (P = 0.025) and the anger expression-in (P = 0.04). Conclusion: Although patients with MS were not significantly different from healthy individuals in terms of intrapsychic and interpersonal functions in the context of object relations and anger management, it seems that more complex and multifaceted explanations lie in the results that need further research.
ABSTRACT
CLINICAL RELEVANCE: Considering the significant relationship between opioid abuse and some accommodative and convergence disorders, opioid use should be considered in the differential diagnosis and will directly affect the management plan. BACKGROUND: To determine the prevalence of accommodative and convergence anomalies and their related factors in a population of male young adults with opioid use disorder (OUD). METHODS: This cross-sectional study was conducted using a convenience sampling method in 2019. The study sample included male young adults with OUD who had been referred to a specialised drug-dependence rehabilitation centre in Mashhad, Iran. The diagnosis of OUD was made by a psychologist based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria. All patients underwent complete optometric examinations. RESULTS: Eighty male young adults with OUD were included in this study. The mean age of participants was 30.5 ± 3.9 years (age range 19 to 35 years). The prevalence of accommodative and convergence disorders was 33.75% (95% CI: 23.55-45.19) and 25.00 (95% CI: 15.99-35.94), respectively. Accommodative insufficiency (22.5%, 95% CI: 13.91-33.21) had a higher prevalence than accommodative excess (3.75%, 95% CI: 0.78-10.57) and accommodative infacility (7.50%, 95% CI: 2.80-15.61). Convergence insufficiency (18.75%, 95% CI: 10.89-29.03) had a higher prevalence compared to convergence excess (3.75%, 95% CI: 0.78-10.57) and basic exophoria (2.50%, 95% CI: 0.30-8.74). According to the multiple logistic regression, a significant inverse relationship was observed between pupil size with accommodative insufficiency (OR = 0.45), accommodative infacility (OR = 0.67), and convergence insufficiency (OR = 0.55). CONCLUSION: The results of the present study showed a higher prevalence of some accommodative and convergence disorders in OUD patients compared to the prevalence reported in previous studies conducted on the normal populations with a similar age range.
