The Independent Contribution of Positive and Negative Metacognitions About Smoking to Urge to Smoke, Withdrawal Symptoms and Dependence in Smoking-Dependent Men.

Previous research has indicated that various factors, such as psychological distress, distress intolerance, anhedonia, impulsivity and smoking metacognitions, have been individually linked to the urge to smoke, withdrawal symptoms and dependence. However, these factors have not been collectively examined to determine whether smoking metacognitions independently and significantly contribute to these outcomes. Therefore, the aim of this study was to investigate the impact of distress intolerance, anhedonia, impulsivity and smoking metacognitions on the urge to smoke, withdrawal symptoms and dependency in men who are dependent on smoking. A total of 300 smoking-dependent men completed psychological scales and smoking-related measures. The findings of the study indicated that positive metacognitions about emotion regulation significantly predicted the urge to smoke, even when accounting for other significant predictors such as the number of daily cigarettes smoked, psychological distress, anhedonia and impulsivity. Furthermore, positive metacognitions about cognitive regulation were found to be a significant predictor of withdrawal symptoms, independent of other significant predictors such as psychological distress and the urge to smoke. Smoking dependence was predicted by negative metacognitions about uncontrollability beyond other significant predictors, including the number of daily cigarettes smoked and distress intolerance. These results highlight the role of metacognitions about smoking in both short- and long-term clinical outcomes related to smoking. Consequently, addressing such beliefs during treatment for smoking dependence should be an important therapeutic goal.

Childhood emotional maltreatment, maladaptive coping and obsessive-compulsive symptoms in patients with obsessive-compulsive disorder.

Previous studies have reported childhood emotional maltreatment (CEM) to be associated with specific obsessive-compulsive (OC) symptoms, but maladaptive coping, which may be the underlying mechanism in this relationship, has not been evaluated yet. Thus, the present study aimed to examine the effects of CEM on the OC symptoms of responsibility for harm and unacceptable thoughts, as well as obsessive-compulsive disorder (OCD) severity, through maladaptive coping, including cognitive avoidance, experiential avoidance and emotional suppression in OCD patients (n = 360). The results showed that CEM had direct effects, as well as indirect effects via cognitive and experiential avoidance and emotional suppression, on responsibility for harm and unacceptable thoughts. In addition, the indirect effect of CEM on OCD severity was significantly mediated by the roles of cognitive avoidance and experiential avoidance. The present study adds new literature to evidence indicating the role of early childhood events in developing and maintaining OCD in which adverse maladaptive coping related to unpleasant childhood abuse plays an important role in OCD. More precisely, OCD patients who experience a history of CEM may further use maladaptive coping to cope with their distress and subsequently experience responsibility for harm, unacceptable thoughts and severe OCD.

The effect of childhood maltreatment on suicidal ideation through cognitive emotion regulation strategies and specific obsessive-compulsive symptoms in obsessive-compulsive disorder.

Childhood maltreatment is thought to be associated with suicidality in patients with obsessive-compulsive disorder (OCD). Although the underlying mechanism of this relationship is not clear, cognitive emotion regulation strategies (CERSs) and the specific OC symptoms including unacceptable obsessional thoughts (UOTs) and responsibility for harm (RFH) may underlie this link. Accordingly, the study aimed to assess the effect of childhood maltreatment on suicidal ideation through UOTs, RFH and adaptive and maladaptive CERSs in OCD patients. Three hundred patients meeting a DSM-5 diagnosis of OCD were selected and completed the scales measuring childhood maltreatment, OCD, suicidality and depressive symptoms. After controlling for depressive symptoms and OCD severity, childhood maltreatment was shown to affect suicidal ideation directly. Also, the indirect effect of childhood maltreatment on suicidal ideation was mediated by adaptive CERSs, UOTs and RFH. The findings show that OCD patients with a history of childhood maltreatment, less use of adaptive CERSs and the experiences of UOTs and RFH should be carefully considered regarding suicidal risk.

Enriched Environment Ameliorates Cognitive Deficits and Locomotor Sensitization in Morphine-Withdrawn Rats Receiving Methadone Maintenance Treatment.

OBJECTIVE: This study was designed to examine whether enriched environments (EE) would attenuate object recognition and spatial learning and memory deficits and locomotor sensitization induced by methadone maintenance treatment (MMT) in morphine-withdrawn rats. METHODS: Male Wistar rats (170 ± 10 g) were injected with bi-daily doses (10 mg/kg, 12-h intervals) of morphine for 14 days. Rats receiving MMT were reared in the standard environment (SE) or EE during 30 days of morphine withdrawal. Then, the rats were tested for object recognition (the object recognition memory test, ORMT) and spatial learning and memory (the water maze) and then challenged with morphine (1 mg/kg, i.p.) and evaluated for locomotor activity (open-field box). RESULTS: The results revealed that the dependent/saline/EE (D/Sal/EE) and D/methadone/EE (D/Meth/EE) rats exhibited significant preference for the new object (p = 0.006 and p = 0.049), spent more time in the target zone (p = 0.045 and p = 0.005) on the water maze, and displayed a lower level of distance traveled (p = 0.002 and p = 0.0001) compared to their control groups reared in SE. CONCLUSIONS: We conclude that exposure to EE could ameliorate the object recognition and spatial memory deficits and also decrease locomotor sensitivity in morphine-withdrawn rats receiving MMT. Thus, EE may be beneficial in the treatment of addiction during MMT.

The Comparison of Death Anxiety, Obsession, and Depression Between Muslim Population with Positive and Negative Religious Coping.

Death anxiety, obsession, and depression constitute three dimensions of death distress which can be influenced by religious coping in religious individuals. The aim of this study was to compare death anxiety, depression, and obsession between Muslims with positive and negative religious coping. In a cross-sectional study, a sample of 339 participants were selected via stratified random sampling method. The participants were screened using the Brief Religious Coping Scale, in which 60 individuals were identified to have positive religious coping and 62 individuals were recognized as individuals with negative religious coping. They responded to Death Anxiety Scale, Death Obsession Scale, and Death Depression Scale. The data were analyzed using factor analysis and multiple analysis of variance. The results of principal component analysis showed that death anxiety, death obsession, and death depression were separate factors of death distress. The results also revealed that individuals with negative religious coping gained higher scores than those with positive religious coping in all the three variables of death anxiety, obsession, and depression. Consistent with the previous studies and Terror Management Theory, this finding lays emphasis on the role of positive religious coping in reducing death distress and the possible consequent psychopathology.

Effect of enriched environment during adolescence on spatial learning and memory, and voluntary consumption of morphine in maternally separated rats in adulthood.

This study was designed to examine the effect of environmental enrichment (EE) during adolescence on spatial learning and memory and voluntary morphine consumption in maternally separated (MS) male and female rats in adulthood. Male Wistar rats were allowed to mate with female virgin Wistar rats. Pups were separated from the dams daily for 180 min during postnatal days 2-14. All pups were weaned on day 21. The pups of both sexes were reared in a standard (SE) or enriched (EE) environment during postnatal days 21-50. Then, adulthood rats were tested for spatial learning and memory (Morris Water Maze), and voluntary consumption of morphine using a two-bottle choice paradigm (TBC). We found that the MS/SE rats showed longer escape latencies to find the platform on the third (the male) and fourth (the female) days of training than No MS/SE rats. Also, exposure to EE shortened the latency to escape in the male and female MS rats as training progressed than MS/SE rats. Moreover, the No MS/EE and MS/EE male rats spent significantly more time in the target zone compared with the SE control groups in the probe test. We also found that voluntary morphine consumption was higher in the male and female MS/SE than No MS/SE rats, while it was lower in the male and female MS/EE rats. The present results have shown that EE treatment may have potential therapeutic application for the prevention of the development of drug addiction and recovery from cognitive deficits following neonatal MS during adulthood.

The effects of emotion dysregulation and negative affect on urge to smoke and nicotine dependence: The different roles of metacognitions about smoking.

Evidence has shown that smoking is a self-regulatory strategy to relieve negative affect and that metacognitions about smoking may play a role in addictive behaviors. Therefore, the present research was designed to examine the direct and indirect roles of emotion dysregulation and negative affect in predicting urge to smoke and nicotine dependence via metacognitions about smoking. In a cross-sectional study, 450 nicotine-dependent men completed measures of urge to smoke, nicotine dependence, metacognitions about smoking, negative affect, and emotion dysregulation. The results showed that both emotion dysregulation and negative affect had indirect effects on urge to smoke via positive metacognitions about smoking as well as on nicotine dependence via negative metacognitions about smoking. The findings suggest that metacognitions about smoking have different roles in different patterns of nicotine use so that positive and negative metacognitions have important roles respectively in urge to smoke and nicotine dependence in smokers with high emotion dysregulation and negative affect. This study also adds to the literature on the metacognitive theoretical framework of addictive behaviors supporting the use of Metacognitive Therapy interventions in smoking cessation.

Anxiety in social interactions and nicotine dependence in nicotine-dependent men: The role of metacognitions about smoking.

Anxiety in social interactions is an important factor in cigarette use and nicotine dependence. Metacognitions about smoking have been found to predict smoking behavior and may help understand the relationship between anxiety in social interactions and nicotine dependence. In the current study, we evaluated the direct effect of anxiety in social interactions on nicotine dependence and its indirect effect through metacognitions (controlling for anhedonia and depression) in nicotine-dependent men (n = 388). Participants completed measures of anxiety in social interactions [the Social Interaction Anxiety Scale (SIAS)], anhedonia [the Snaith HamiltonPleasure Scale (SHAPS)], metacognitions about smoking [e.g., theMetacognitions aboutSmoking Questionnaire (MSQ)] nicotine dependence [the Fagerström Test for Nicotine Dependence (FTND)], and clinical factors related to smoking including depressive symptoms [e.g., the Beck Depression Inventory-II (BDI-II)]. As expected, after controlling for depressive symptoms and anhedonia, anxiety in social interactions indirectly affected nicotine dependence through negative metacognitions about smoking, but not positive metacognitions. These findings are discussed in relation to the metacognitive model of addictive behaviors.

Environmental Enrichment Ameliorates Psychological Dependence Symptoms and Voluntary Morphine Consumption in Morphine Withdrawn Rats Under Methadone Maintenance Treatment.

INTRODUCTION: Previous studies have shown that physical and psychological dependence and the vulnerability to relapse are still present during MMT. Thus, this study examined whether Enriched Environment (EE) would attenuate anxiety, depressive, and obsessive-compulsive-like behaviors, as well as voluntary morphine consumption following Methadone Maintenance Treatment (MMT) in morphine withdrawn rats. METHODS: The rats were injected bi-daily doses (10 mg/kg, 12-h interval) of morphine for 14 days. Then, the rats were reared in a Standard Environment (SE) or EE for 30 more days during morphine withdrawal, simultaneous with receiving MMT. The rats were tested for anxiety (the Elevated Plus Maze [EPM]) and depression (Sucrose Preference Test [SPT]), Obsessive-Compulsive Disorder (OCD) as grooming behavior, and voluntary morphine consumption using a Two-Bottle Choice (TBC) paradigm. RESULTS: The findings revealed that EE experience in morphine withdrawn rats under MMT significantly increased the EPM open-arm time and higher sucrose preference than SE rats. Also, we found that the EE decreased the self-grooming behavior and morphine preference ratio in morphine withdrawn rats receiving MMT compared to the SE group. CONCLUSION: We conclude that exposure to EE decreased methadone-induced anxiety, depressive and OCD-like behaviors, and voluntary morphine consumption in morphine withdrawn rats under MMT. Thus, the EE seems to be one of the strategies for reducing MMT-induced behavioral dysfunction and the risk of relapse induced by morphine withdrawal.

Family communication patterns of individuals with and without disabilities.

The aim of this study was to compare family communication patterns among Iranian individuals with blindness, deafness and individuals with typically developing. The statistical population consisted of all Iranian individuals with blindness, deafness and individuals with typically developing in Shiraz, Iran. The sample consisted of 116 individuals (32 individuals with blindness, 21 individuals with deafness, and 63 individuals with typically developing). The Revised Family Communication Patterns scale was used for measuring the family communication patterns. Multivariate analysis of variance test were used for data analysis. The results showed that conversation orientation in individuals with typically developing were significantly higher than individuals with blindness and deafness (P<.001). Furthermore, conversation orientation in individuals with blindness was significantly higher than individuals with deafness (P<.001). Moreover, the findings showed that the conformity orientation in individuals with blindness and deafness were significantly higher than individuals with typically developing (P<.001). It should be noted that there was no significant difference among individuals with blindness and deafness in terms of conformity orientation. The results of the study indicated that reforming of family communication patterns is essential for individuals with blindness and deafness.

The psychometric properties of the Persian version of the metacognitions about Smoking Questionnaire among smokers.

OBJECTIVES: It has been shown that smoking may be affected by metacognitions. This study aimed to evaluate the factor structure, reliability and validity of the Persian version of the Metacognitions about Smoking Questionnaire (MSQ) among a sample of Iranian male smokers. METHODS: When the English to Persian translation of the MSQ was performed, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were completed according to the four-factor solution of the original MSQ. Three hundred male treatment-seeking smokers (mean age = 41.37, SD = 15.90) filled out the Persian-translated version of the MSQ, the Smoking Effects Questionnaire (SEQ), and the Nicotine Dependence Syndrome Scale (NDSS). RESULTS: The results of EFA revealed that the Persian version of the MSQ had a four-factor structure named positive metacognitions about cognitive regulation (PM-CR), positive metacognitions about emotional regulation (PM-ER), negative metacognitions about uncontrollability (NM-U), and negative metacognitions about cognitive interference (NM-CI). The findings of CFA also indicated that the four-factor structure of the Persian version of the MSQ had appropriate fit. Validity and reliability of the Persian version of the MSQ were found to be good. Negative metacognitions about smoking predicted nicotine dependence over and above smoking outcome expectancies. Positive metacognitions about emotion regulation explained daily cigarette use independent of smoking outcome expectancies. CONCLUSIONS: The findings suggested that the Persian version of the MSQ had adequate psychometric properties among Iranian male treatment-seeking smokers.

Effect of exercise augmentation of cognitive behavioural therapy for the treatment of suicidal ideation and depression.

BACKGROUND: Suicidal ideation and depression are prevalent and costly conditions that reduce quality of life. This study was designed to determine the efficacy of exercise as an adjunct to cognitive behavioural therapy (CBT) for suicidal ideation and depression among depressed individuals. METHODS: In a randomized clinical trial, 54 mildly to moderately depressed patients (54% female, mean age=48.25) were assigned to a combined CBT and exercise group or to a CBT only group. Both groups received one weekly session of therapy for 12 weeks, while the combined group also completed exercise three times weekly over the same period. Self-reported suicidal ideation, depression, and activities of daily living were measured at the beginning and the end of treatment. RESULTS: Multilevel modelling revealed greater improvements in suicidal ideation, depression, and activities of daily living in the combined CBT and exercise group, compared to the CBT only group. LIMITATIONS: No follow-up data were collected, so the long-term effects (i.e., maintenance of gains) is unclear. CONCLUSIONS: The findings revealed that exercise adjunct to CBT effectively decreases both depressive symptoms and suicidal ideation in mildly to moderately depressed individuals.
