주의력결핍-과잉활동장애(ADHH)는 그 행동적 특징이 정상아동들간에도 흔히 나타날 수 있는 것으로 정상적 발달과정에서 나타나는 현상과의 구별이 어려운 경우가 있어 증상의 심각도를 양적수치로 평가하는것과 아울러 함께 각 연령별 규준에 비추어 판단하는 객관적 평가방법이 필요하다. 또한 ADHD의 증상은 상황에 따라, 그리고 사회적 맥락에 따라 나타나는 양상이 크게 다를수도 있어 가능한한 다양한 상황에서의 행동을 여러 평가자로부터 평가받아 이를 통합하는 과정이 필요하다. 구체적으로 부모 및 환아와의 면담, 각종 행동평가 척도, 행동의 관찰, 그리고 심리검사등 ADHD를 평가할 때 사용할 수 있는 방법 및 척도들이 논의되었으며, 평가의 목적에 따라 적절한 도구를 선택하여 활용하는 체계적이고 종합적인 평가의 중요함이 강조되었다.

This study analyzed the effect of family meals on the psychological problems of children. We performed focus group interviews (FGI) on the basic characteristics of family meals, and chose several scales (such as Child Behavior Checklist (CBCL), self-esteem, and a daily hassles questionnaire), to measure the psychological variables. We collected data from 442 dyads (mother-child) and used 440 from dyads. In our results, the frequency of family meals affected the psychological problems of children, especially aggression and emotional instability. The atmosphere during meals also affected depression/anxiety, concentration difficulties, emotional instability, self-esteem, peer relationships, and sociality. There were significant correlations between meal atmosphere, family bonding, maternal personality, and psychological problems of children. We performed covariation analysis to examine and control the influence of family bonding and maternal personality; despite controlling for these variables, family meals still influenced children's psychological problems. We conclude that the family meal is a significant variable that impacts the emotional and behavioral problems of children and stress the importance of frequent family meals.

Purpose: The purpose of this study was to understand and describe the every day life experience of patients with acute myocardial infarction (AMI) during the recovery period after Percutaneous Coronary Intervention (PCI) using a qualitative approach. Methods: Twelve patients with AMI participated in this study. Their age ranged from 42 to 75. The data were collected by individual in-depth interviews and all interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed using traditional qualitative content analysis. Results: Six sub-themes emerged from the data as follows: Getting to know about illness, getting motivated for health behavior, putting an effort into health behavioral change, having difficulties maintaining health behavior, setting up coping strategies for health behavior and having a need for a tailored education. The results of this study showed how the health behaviors of patients with AMI are related to their every day life experiences. Conclusion: The results of this study could help health professionals to better understand patients with AMI and design effective educational interventions to improve their health behaviors.

In research on behavioral studies, significant attention has been paid to the stage-sequential process for longitudinal data. Latent class profile analysis (LCPA) is an useful method to study sequential patterns of the behavioral development by the two-step identification process: identifying a small number of latent classes at each measurement occasion and two or more homogeneous subgroups in which individuals exhibit a similar sequence of latent class membership over time. Maximum likelihood (ML) estimates for LCPA are easily obtained by expectation-maximization (EM) algorithm, and Bayesian inference can be implemented via Markov chain Monte Carlo (MCMC). However, unusual properties in the likelihood of LCPA can cause difficulties in ML and Bayesian inference as well as estimation in small samples. This article describes and addresses erratic problems that involve conventional ML and Bayesian estimates for LCPA with small samples. We argue that these problems can be alleviated with a small amount of prior input. This study evaluates the performance of likelihood and MCMC-based estimates with the proposed prior in drawing inference over repeated sampling. Our simulation shows that estimates from the proposed methods perform better than those from the conventional ML and Bayesian method.

Working memory (WM), which plays a vital role in daily activities, is a memory system that temporarily stores and processes information when people are engaged in complex cognitive activities. The influence of music on WM has been widely studied. In this work, we conducted a series of n-back memory experiments with different task difficulties and multiple trials on 14 subjects under the condition of no music and Alpha wave leading music. The analysis of behavioral data show that the change of music condition has significant effect on the accuracy and time of memory reaction (p<0.01), both of which are improved after the stimulation of Alpha wave music. Behavioral results also suggest that short-term training has no significant impact on working memory. In the further analysis of electrophysiology (EEG) data recorded in the experiment, auto-regressive (AR) model is employed to extract features, after which an average classification accuracy of 82.9% is achieved with support vector machine (SVM) classifier in distinguishing between before and after WM enhancement. The above findings indicate that Alpha wave leading music can improve WM, and the combination of AR model and SVM classifier is effective in detecting the brain activity changes resulting from music stimulation.

Providing care to the dementia elderly with behavioral problem is a major issue in nursing homes today. This study was aimed to explore the nursing staffs′ response to aggressive dementia patients, and the effect that the aggressive behavior had on Nsgstaff. The interviews used a semi-structured questionnaire are were carried out from May to July, 1999. The subjects were 23 nursing personnel working in the nursing homes for dementia elderly. The result are as follows; 1. The types of aggressive behavior cited by the subjects was "physical", "linguistic", and "sexual". 2. The factors that caused the behavior were "symptoms of disease", "under- conditioning", "context of nursing care", "unsatisfied need", "relationship to other patients", "change of outer environment", and "invasion of one′s own privacy". 3. The response of the subjects were "unhappiness", "stress", "anger", "exaggeration", "anxiety", and "fear". 4. The management strategies listed by nursing personnel used to alleviate aggressive behavior were "ignorance" "patience" "leaving the area" "soothing sounds" "verbal punishment" "restriction and isolation" and "various management skill appliance" "adaptation". 5. The effect that aggressive behavior and were "disturbance of relationship to elderly" "decline in the amount and quality of nursing care" "interruption of task performance" "job exhaustion" "desire to leave the job" "physical impact" "stress on the cognition of others" "anxiety about health and one own future" "interference to family life′. The findings of this study will be useful in understanding the difficulties of nursing personnel when confronting the aggressive behavior of dementia partients. It also is useful as basic data in preparing efficient intervention program for these difficulties.

Objective : This study is planned to determine the neurocognitive difficulties of hydrocephalic adults. Methods : The research group contained healthy adults (control group, n : 15), and hydrocephalic adults (n : 15). Hydrocephalic group consisted of patients with idiopathic aquaduct stenosis and post-meningitis hydrocephalus. All patients were followed with shunted hydrocephalus and not gone to shunt revision during last two years. They were chosen from either asymptomatic or had only minor symptoms without motor and sensorineural deficit. A neuropsychological test battery (Raven Standart Progressive Matrices, Bender-Gestalt Test, Cancellation Test, Clock Drawing Test, Facial Recognition Test, Line Orientation Test, Serial Digit Learning Test, Stroop Color Word Interference Test-TBAG Form, Verbal Fluency Test, Verbal Fluency Test, Visual-Aural Digit Span Test-B) was applied to all groups. Results : Neuropsychological assessment of hydrocephalic patients demonstrated that they had poor performance on visual, semantic and working memory, visuoconstructive and frontal functions, reading, attention, motor coordination and executive function of parietal lobe which related with complex and perseverative behaviour. Eventually, these patients had significant impairment on the neurocognitive functions of their frontal, parietal and temporal lobes. On the other hand, the statistical analyses performed on demographic data showed that the aetiology of the hydrocephalus, age, sex and localization of the shunt (frontal or posterior parietal) did not affect the test results. Conclusion : This prospective study showed that adult patients with hydrocephalus have serious neuropsychological problems which might be directly caused by the hydrocephalus; and these problems may cause serious adaptive difficulties in their social, cultural, behavioral and academic life.

BACKGROUND/OBJECTIVES: The purpose of this study is to utilize an extended Theory of Planned Behavior in identifying predictors of exclusive breastfeeding intention and behavior among women in Kelantan, Malaysia. SUBJECTS/METHODS: A prospective cohort study was conducted, recruiting pregnant womenthrough two-stage cluster sampling. Their exclusive breastfeeding intention, attitude, perceived norm, perceived behavioral control and past behavior were obtained at baseline through interviewer-guided questionnaire. At one month after delivery, another interview was conducted to determine the two additional variables in the extended theory, which were their postpartum support and breastfeeding difficulty. The behavior, which was the actual duration of exclusive breastfeeding, was obtained from the second follow-up at six months. Pearson correlation and two hierarchical regression analyses were conducted. RESULTS: A total of 200 women completed the study follow-up. Their median intended exclusive breastfeeding duration was 4.0 (IQR 5) months, and the median actual duration was 1.0 (IQR 4) month. The Theory of Planned Behavior explained 51.0% of the variance in intention, with perceived behavioral control and attitude were the significant predictors. It also explained 10.0% of the variance in behavior, but the addition of postpartum support and breastfeeding difficulty increased the amount of explained variance in behavior by 6.0%. The significant predictors of exclusive breastfeeding behavior were intention, postpartum support and breastfeeding difficulty. CONCLUSION: The extended Theory of Planned Behaviorhad a good predictive ability in explaining exclusive breastfeedingintention and behavior. The women's intention to practice exclusive breastfeeding may be improved by improving their perceived behavioral control and attitude. Providing correct postpartum support and skills to handle breastfeeding difficulties after delivery will improve their exclusive breastfeeding behavior.

Purpose: This study aims to explore the association between unemployment and depression in people from different age groups ranging from 18 to 65 years old. Methods: This study used a cross-sectional design. We performed bivariate analysis and multivariable logistic regression on the 2010 Behavioral Risk Factor Surveillance System (BRFSS) data from 12 states in the United States. Results: On a sample comprised of n=53,406 individuals, of whom 2,546 (7.8%) were identified as being depressed and 3,448 (10.6%) as unemployed, we found that individuals aged 61~65 years have a lower depression risk compared to those aged 18-25 after adjusting for other variables including employment status. However, people from 61~65 have higher increased risk of depression when unemployed compared to other age groups in all three models tested (3.95 times higher in unemployed people in model 1, and 2.81 times higher in model 2 and model 3). Conclusion: Our findings indicate that there may need to be more focus on older adults who are unemployed, with associated support services for their mental health. The results of our study indicate that although older adults are less likely to be unemployed, there are more likely to experience depression if they are unemployed (once other confounding factors are taken into account) than younger adults. Policies and interventions can be developed to address not only the physical difficulties but also the mental challenges with which older adults can be at risk facing in case of unemployment.
