Effectiveness of parent training in improving stress-coping capability, anxiety, and depression in mothers raising children with autism spectrum disorder.

PURPOSE: Raising a child with autism spectrum disorder (ASD) can be a stressor, and mothers of ASD children often present with high levels of stress and depression. Interventional steps to enhance parental coping skills and resiliency are more important for parental mental health and the family-centered care of children with ASD than merely reducing parental stress. Although the importance of stress-coping skills is well established, only a few studies have investigated interventional steps to improve parental coping or resiliency. Parent training (PT) is known to improve a mother's mental health. Here, we aimed to assess the effectiveness of PT in improving the stress-coping style of mothers raising children with ASD. PATIENTS AND METHODS: Thirty mothers of children with ASD aged 4-11 years participated in this study. The mothers underwent PT based on the Hizen Parenting Skills Training in Japan, which comprised seven sessions. Each session included education on behavior therapy, individual consultation, and workshops in small groups. Sixteen mothers completed psychological assessment, including the Stress Coping Inventory, the Beck Depression Inventory Second Edition, the State-Trait Anxiety Inventory, and the Child Behavior Checklist conducted before and after 2 months of PT. RESULTS: The outcomes before and after the PT program were compared using the paired t-test and Pearson's correlation. After the PT program, the mothers' stress-coping strategy "positive appraisal" significantly increased (P<0.01) and "escape/avoidance" significantly decreased (P<0.01). The Beck Depression Inventory Second Edition (P<0.05) and the trait anxiety scores (P<0.01) also significantly decreased. The change in the stress-coping strategy "distancing" had a significantly negative correlation with the change in the externalizing Child Behavior Checklist T-scores of children with ASD (Pearson r=-0.518, P<0.05). CONCLUSION: PT may be effective for mothers of children with ASD to improve their stress-coping style and to decrease their depression and trait anxiety.

A tract-based spatial statistics study in anorexia nervosa: abnormality in the fornix and the cerebellum.

There has been an increasing interest in white matter abnormalities in patients with anorexia nervosa (AN). However, to date, there have been only a few diffusion tensor imaging (DTI) studies investigating AN, and the results are inconsistent. In this study, we employed tract-based spatial statistics (TBSS), a robust technique for whole-brain analysis of DTI data, to detect white matter abnormalities in AN patients compared with healthy controls. Seventeen women with AN and 18 age matched healthy women were included. The mean body mass index of patients was 13.6 kg/m(2) (controls: 19.9 kg/m(2)). DTI data were acquired on a 3-Tesla magnetic resonance imaging system. Fractional anisotropy (FA) and mean diffusivity (MD) maps were calculated from the DTI data of each patient, and voxel-wise group comparisons of FA and MD were performed using TBSS. Compared with the healthy comparisons, the patients showed a significantly higher MD value in the fornix and lower FA value in the left cerebellum. We also found significant positive correlations between the mean FA value of the left cerebellar hemisphere cluster and BMI, as well as between the mean MD value of the cluster in the anterior body of the fornix and the duration of illness. The results suggest that the white matter abnormalities in the fornix and the cerebellum may be related to the pathophysiology of AN.

Predictors for exacerbation/improvement of postpartum depression--a focus on anxiety, the mothers' experiences of being cared for by their parents in childhood and borderline personality: a perspective study in Japan.

OBJECTIVE: To investigate the course and influencing factors of postpartum depression in women during the child rearing period. METHODS: Data were collected during 0-year-old baby check-ups and a follow-up investigation. 262 participants were included in the analysis. Both surveys employed the Zung Self-Rating Depression Scale (ZSDS). The first also comprised the State Trait Anxiety Inventory, Parental Bonding Instrument (PBI), and Borderline Scale Index, enabling sub-division of participating subjects into healthy/pathological groups. ZSDS group and survey scores were compared using the t-test. RESULTS: The average ages of the children and the ZSDS scores in both surveys were 7.0±3.2 and 21.8±2.4 months, 40.6±7.9 and 40.1±8.7, respectively, with no significant differences among depression scores. When subjects were divided according to individual scale scores, and survey scores compared, depression significantly improved in the high trait/state anxiety group, high PBI maternal care score group, nonborderline personality (BP) trait group, and breast feeding group, whereas depression was significantly exacerbated in the low PBI maternal care score group. DISCUSSION: Postpartum depression characterized by strong anxiety and a depressive state in mothers with favorable psychological backgrounds showed gradual improvement. We noted an exacerbation of depression during the separation period in mothers who had received poor maternal care. We assume that the feeling of abandonment induced by individuation of their children is a major factor. LIMITATIONS: There is concern that some depressive women may have dropped out due to a performance bias. CONCLUSIONS: Sharing our findings about exacerbation/improvement of depression among medical staff may be beneficial for postpartum mothers.

Parental bonding in patients with eating disorders and self-injurious behavior.

AIM: The goal of the study was to investigate the correlations among parental bonding patterns, eating disorders (ED) and self-injurious behavior (SIB). METHODS: The subjects were 80 patients with ED who were divided into two groups based on those that had (n = 25) and had not engaged in SIB at least once in the last month. The patients and 120 healthy control subjects were evaluated using the Eating Disorder Inventory and the Parental Bonding Instrument. RESULTS: On the Parental Bonding Instrument, the ED + SIB group showed significantly lower paternal care compared with the ED/no SIB and control groups. On the Eating Disorder Inventory, the ED + SIB group showed higher body dissatisfaction, and increased maturity fear compared with the other two groups. The total scores and perfectionism and interoceptive awareness differed significantly among the three groups. CONCLUSION: ED + SIB patients had a more severe ED pathology than ED/no SIB patients, and also felt that they had received low paternal care during childhood. Therefore, paternal care may be linked to severe ED pathology.

Factors associated with postpartum depression and abusive behavior in mothers with infants.

AIMS: This study was conducted to examine factors associated with postpartum depression and abusive behavior in mothers with infants. METHODS: Data were collected from baby check-ups in Japan and 413 participants were included in an analysis using: (i) an Original Questionnaire; (ii) the Zung Self-rating Depression Scale (ZSDS); (iii) the Parental Bonding Instrument; and (iv) the Childcare Anxiety Scale (CAS). Covariance structural analyses were performed to examine interconnections among the Parental Bonding Instrument subscales, CAS subscales ('worry about parenting', 'burden of nursing time', 'difficulty of bonding'), ZSDS, 'fear of being abusive', and 'abusive behavior'. RESULTS: Of the 413 mothers, 14.5% showed higher than moderate levels of depression (ZSDS > or = 50). In covariance structural analyses, 'depression' was strongly influenced by 'worry about parenting' in all variances, but was not associated with 'abusive behavior'. 'Worry about parenting' also had a strong influence on 'fear of being abusive', but did not affect 'abusive behavior'. Low 'maternal care' had most influence on 'difficulty of bonding', and 'difficulty of bonding' only affected 'abusive behavior'. CONCLUSIONS: The outcome of this study suggests that excessive worrying related to postpartum depression, 'fear of being abusive', and bonding difficulty are primary predictors of child abuse. Postpartum depression was not a predictor for abusive behavior after exclusion of the impact of bonding difficulties on abusive behavior. Therefore, the correlation between postpartum depression and abusive behavior identified in previous reports may have been influenced by bonding difficulties.

Classification of adult patients with type 2 diabetes using the Temperament and Character Inventory.

AIM: Adult patients with type 2 diabetes were classified using the Temperament and Character Inventory (TCI). This classification was used to propose effective therapeutic approaches based on subtypes of psychological characteristics. METHODS: The TCI and various psychological tests were administered to 89 patients (54 men and 35 women). Cluster analysis was performed using three temperament factors of the TCI as variables for subclassification: novelty seeking (NS), harm avoidance (HA) and reward dependence (RD). RESULTS: The patients were divided into two clusters based on the TCI results. Cluster 1 had a low NS/high HA/low RD pattern, which indicated resistance to change and lack of cooperativeness, and results of other tests indicated that patients in cluster 1 were obsessional and had weak intention and personality disorder symptoms. In contrast, cluster 2 had a high NS/low HA/high RD pattern, indicating a socially active person who easily becomes dependent on others, and results of other tests indicated that these patients were histrionic and less anxious. In cluster 1 there was a significant negative correlation between hemoglobin A1c (HbA1c) and SD-1 (TCI self-directedness) 'responsibility' and a significant positive correlation between HbA1c and State anxiety of State-Trait Anxiety Inventory. In cluster 2 there was a significant positive correlation between HbA1c and HA-2 'fear of uncertainty'. CONCLUSIONS: Patients with type 2 diabetes were classified using the TCI into two subgroups. These two groups differed in psychological characteristics and had a different pattern in correlation with glycemic control.

Effects of rat medial prefrontal cortex lesions on olfactory serial reversal and delayed alternation tasks.

When reward reinforcement in a two-choice discrimination task is regularly changed from one stimulus to another immediately after one learning acquisition session, the learning efficiency of a rat increases as if the rat has come to recognize this regularity of reversal. To investigate how the rat medial prefrontal cortex (mPFC) is involved in such improvement, we examined the performance of mPFC-lesioned rats in a serial reversal task of olfactory discrimination. The performance of other mPFC-lesioned rats in a delayed alternation task was also analyzed using the same apparatus to evaluate the contribution of the mPFC to working memory. The mPFC-lesioned rats demonstrated selective difficulty in the second reversal session in the serial reversal task and also showed performance impairment in the delayed alternation task. These results suggest that the rat mPFC mediating working memory is involved in early progress in learning efficiency during experiences of multiple reversals, which may be relevant to cognitive operations in reversal learning beyond a one-time reversal of stimulus response associations.

Regional cerebral blood flow changes associated with interoceptive awareness in the recovery process of anorexia nervosa.

BACKGROUND: An abnormality in regional cerebral blood flow (rCBF) in anorexia nervosa (AN) patients has been reported. There are very few studies that have investigated the rCBF changes in the recovery process of AN. METHODS: For eight female AN patients, we performed (123)I-IMP single photon emission computed tomography (SPECT) and four psychological assessments (Eating Disorder Inventory (EDI), Eating Attitude Test (EAT), Self-Rating Depression Scale (SDS) and State-Trait Anxiety Inventory (STAI)) both before and after inpatient-behavioral therapy. SPECT images were analyzed using statistical parametric mapping software. We also performed correlational analysis between rCBF and clinical variables. RESULTS: Following treatment, the patients showed significant body weight recovery. They showed significant improvement in EAT, SDS, STAI and a subscale of EDI - interoceptive awareness (IA) - but not in total EDI or other EDI subscales. Significant rCBF increases were observed in the precuneus, posterior cingulate cortex (PCC), right dorsolateral prefrontal cortex (DLPFC), anterior cingulate cortex (ACC) and medial prefrontal cortex (MPFC) by the treatment. Significant correlation was observed between rCBF of right DLPFC and IA score before treatment. CONCLUSIONS: Changes of rCBF in right DLPFC, ACC, MPFC, PCC and precuneus were related to the AN recovery process and might be associated with improvement of IA following treatment.

Effect of institutional smoking prohibition on Japanese inpatients with chronic schizophrenia.

OBJECTIVE: A higher prevalence of smoking among schizophrenic patients has been well documented in Japan and other countries. Smoking reduction or cessation is desirable to reduce various physical complications in schizophrenic patients, but the effect of smoking reduction on psychiatric status and BMI remains ambiguous. The aim of this study was to determine the effect of an institutional smoking prohibition on smoking status, psychiatric status and BMI in Japanese inpatients with schizophrenia. METHOD: Smoking status, psychiatric status (Clinical Global Impression (CGI) scores: global severity score and global change score) and BMI were investigated in 256 chronic schizophrenic inpatients before and 3 months after prohibition of smoking in a Japanese psychiatric hospital building. RESULTS: Following prohibition, the smoking rate decreased from 36.3% to 22.2%. A weak positive correlation was found between decreased cigarette consumption and the CGI global change score (r=0.140, p=0.025), but the mean global change scores in the smoking groups were less than 6 (minimally worse). No significant increase in BMI was observed. CONCLUSION: Institutional smoking prohibition is effective in reducing the smoking rate, while having only a minor unfavorable effect on psychiatric status and BMI in chronic schizophrenic inpatients.

Regional cerebral blood flow changes in a patient with delusional parasitosis before and after successful treatment with risperidone: a case report.

The pathophysiology and appropriate pharmacological interventions for delusional parasitosis (DP) remain unknown. Here, we present a case of DP following brain infarction of the right temporoparietal region. Pharmacotherapy with risperidone resulted in a dramatic therapeutic response over a short period. In a sequential N-isopropyl-p-[(123)I]-iodoamphetamine single photon emission computed tomography ([(123)I]-IMP SPECT) study, post-treatment SPECT images revealed a marked increase of rCBF in the large areas including the bilateral frontal and left temporoparietal regions, the right parietal operculum and the bilateral basal ganglia, in contrast to pre-treatment SPECT images showing a global decrease of rCBF. Our clinical outcome suggests the efficacy and safety of risperidone for treatment of DP and that both dopaminergic and serotonergic dysfunction may play a role in DP. Our sequential SPECT findings suggest that psychiatric improvement of DP is associated with increased rCBF.

[Case report of pentazocine dependence from a standpoint of the cognitive therapy].

Drug dependence is a social problem of over the world and resistant to medical intervention by psychiatrist as well as general clinicians. In Japan, methamphetamine dependence is one of the most critical social problems, but opioid dependence is relatively rare. Pentazocine was called the non-addictive opioid at the time of development and release and there are few reports of its dependence. We experienced a medical worker with pentazocine dependence. He started to use pentazocine to reduce serious migraine and felled into dependence by changing the purpose to relaxation of stammering fear and strain towards other people. He was successfully treated by cognitive therapy.

Japanese version of the Body Attitude Test: its reliability and validity.

The Body Attitude Test (BAT) was developed by Probst et al. (1995) for female patients with eating disorders (ED). This test measures the subjective body experience and attitudes toward one's body. The present authors have developed the Japanese version of the BAT and the purpose of the present paper was to investigate its reliability and validity in control (CON, n = 599) and ED patients (n = 46). The ED patients consisted of 21 anorexia nervosa, restricting type (AN-R) patients and 25 bulimia nervosa (BN) patients. Internal consistency was determined with Cronbach's alpha coefficient in CON. Factor analysis was conducted on BAT ratings given by CON. Factor analysis indicated that BAT was composed of two factors. These were body dissatisfaction (factor 1) and lack of familiarity with one's body (factor 2). A comparison was made among AN-R, BN, and CON. Bulimia nervosa had a significantly higher score than the other two groups. The BAT scores of ED patients correlated significantly with the Self -rating Depression Scale, and State-Trait Anxiety Inventory. These results show that ED patients have negative feelings toward their own body, similar to the findings in the original report. On factor analysis, however, it was not possible to distinguish between negative appreciation of body size and general body dissatisfaction as described in the original report. The authors also examine influences on this difference from a cross-cultural view point.

Seasonal variations in eating disorder subtypes in Japan.

OBJECTIVE: This study estimated the degree of seasonal changes in eating disorder subtypes in Japan. METHOD: A Japanese version of the Seasonal Pattern Assessment Questionnaire (SPAQ) was mailed to 228 outpatients with eating disorders in Kyoto (latitude 35 degrees 01' N). Ninety responses were analyzed. The mean of the global seasonality score (GSS) in the SPAQ and the comorbidity rate of seasonal affective disorder (SAD) and subsyndromal-SAD in each subtype were used as indices of seasonality. RESULTS: The mean (8.2) of the GSS of the bulimia nervosa (BN) group and the sum (43%) of the comorbidity rates of SAD and subsyndromal-SAD in the BN group were significantly higher than those in the nonclinical comparison group. DISCUSSION: The seasonality of BN in Kyoto is the highest among eating disorder subtypes, although lower than that in North America. This finding suggests that light therapy could be useful for Japanese BN patients.
