Prevalence of maladaptive behavior in retarded children as a function of IQ and age

One hundred and twentyeight mentally retarded children, ages 6 to 14, from a special school were assessed by teachers in terms of nine maladaptive behaviors. The results indicated that the prevalence of some maladaptive behaviors changed as a function of IQ and age, and that there were splits of such changes as IQ-dependent and as age-dependent by maladaptive behavior.     

Community Psychology in Japan: A Historical Review

Dans cette rétrospective historique, nous retraçons le développement de la communauté psychologique japonaise des années 1960 aux années 1980 en distinguant trois périodes: la période de démarrage (fin décennie 60), la période allant de la naissance aux premiers balbutiements (décennie 70) et la période du développement et de l'indépendance (décennie 80). De plus, nous précisons le statut actuel de la communauté psychologique japonaise et présentons une brève discussion sur les problémes à règler dans le futur.
In this historical review, we trace the development of Japan's community psychology from the 1960s to the 1980s by dividing it into three periods: the quickening period (late 1960s), a period from birth to toddling age (1970s) and a period of development and independence (1980s). In addition, we outline the present status of Japan's community psychology and present a brief discussion on some problems to be addressed in the future.     

Relationships among mental health,coping styles,and mood

The present study investigated the relationships between mental health (measured by the General Health Questionnaire--6 factors: General Illness, Somatic Symptoms, Sleep Disturbance, Social Dysfunction, Anxiety and Dysphoria, Suicidal Depression), coping styles (two strategies: Cognitive centered, Emotional centered), and mood (Tense Arousal, Energetic Arousal). 96 students answered questionnaires before their semester test which was a stressor. Analysis showed that (1) Tense Arousal scores correlated positively with overall General Health scores and all General Health factor scores, and Energetic Arousal scores correlated negatively with overall General Health scores and all General Health factor scores except one; (2) Anxiety and Dysphoria scores predicted Tense Arousal scores the best of General Health factor scores, while both Social Dysfunction scores and General Illness scores predicted Energetic Arousal scores. (3) Participants with high Energetic Arousal scores used a Cognitive centered coping strategy much more than an Emotional centered coping strategy. That is, people with low Energetic Arousal scores seem to use the Emotional centered coping strategy and have anxiety/dysphoria, while people with high Energetic Arousal scores seem to use a Cognitive centered coping strategy and have good health and social activity. These results suggest that there are small but significant relationships among mental health, coping styles, and mood.     

The genetic structure of Cloninger's seven-factor model of temperament and character in a Japanese sample

Theoretical assumptions regarding the genetic and environmental structure of personality proposed in Cloninger's seven-factor model of temperament and character were verified in a Japanese sample by using the twin method. The Temperament and Character Inventory (TCI) was administered to 296 twin pairs ranging in age from 14 to 28 years old. Among four temperament dimensions (novelty seeking [NS], harm avoidance [HA], reward dependence [RD], and persistence [PS]), HA and PS showed significant additive genetic contributions and no shared environmental effect, supporting the original theoretical assumption. NS and RD could be explained by either genetic or shared environmental factors with nonshared environment. All three character dimensions (cooperativeness [CO], self-directedness [SD], and self-transcendence [ST]) could be explained exclusively by additive contributions and no shared environmental effect. Multivariate genetic analysis indicated that there were no significant associations between NS, HA, and RD, as the theory predicts, and the genetic components of PS, SD, and CO were derived from those of the temperament dimensions. The fourth genetic component, which had a substantial load specifically on ST and overlapped with PS, was identified. Although most of the nonshared environmental effects were trait-specific, the phenotypic correlation between NS and HA could be explained by nonshared environmental overlap.     

The effects of short- and long-term life review interview on the psychological well-being of young adults

The present study investigates the effects of short- and long-term life review interviews on young adults' psychological well-being. Study 1 investigates mood using the Japanese UWIST adjective checklist (yielding two scores: Tense Arousal which represents low hedonic tone and Energetic Arousal which represents high hedonic tone). Results show that Energetic Arousal significantly increased after life review, although Tense Arousal did not change. Study 2 investigates self-esteem and mental health (measured by the General Health Questionnaire-6 factors: General Illness, Somatic Symptoms, Sleep Disturbance, Social Dysfunction, Anxiety and Dysphoria, Suicidal Depression). Both self-esteem and mental health scores increased after life review. With regard to factors of mental health, General Illness and Anxiety Dysphoria scores were much higher than those on Somatic Symptoms, Sleep Disturbance, Social Dysfunction, and Suicidal Depression. There was also a significant difference between before and after scores on General Illness, Somatic Symptoms, Sleep Disturbance, and Anxiety Dysphoria, but not in Social Dysfunction and Suicidal Depression. That is, short-term life review led to higher hedonic tone scores, and long-term life review led to better mental health scores in healthy young adults. These results suggest that both short- and long-term life review in an interview promote young adults' immediate psychological well-being. Further research is required for young adults who have psychological problems.     

Covariance structure of neuroticism and agreeableness: a twin and molecular genetic analysis of the role of the serotonin transporter gene

The Revised NEO Personality Inventory domains of Neuroticism and Agreeableness are considered factorially distinct despite several intercorrelations between these domains. The genetic correlation, an index of the degree to which these intercorrelations are caused by genetic influences, was estimated using data from 913 monozygotic and 562 dizygotic volunteer twin pairs from Canada, Germany, and Japan. The serotonin transporter gene, 5-HTTLPR, was assayed in a sample of 388 nontwin sibling pairs from the United States to determine the contribution of the serotonin transporter locus to the covariation between the Neuroticism and Agreeableness scales. In all four samples, genetic influences contributed to the covariance of Neuroticism and Agreeableness, with the serotonin transporter gene accounting for 10% of the relationship between these domains.     

Development of the Brief Personal Values Inventory for Sense of Values

The Portrait Values Questionnaire (PVQ) is a widely used questionnaire for assessing sense of values; however, it is difficult to apply for children and adolescents. Therefore, the present study aimed to develop a questionnaire for sense of values, called the Brief Personal Values Inventory (BPVI), consisting of simple questions and fewer items compared to the PVQ. We first created 12 items for the BPVI and then tested criterion-related validity with values in the PVQ-57 in 167 Japanese general population participants (81 males, mean age [SD], range: 23.4 [8.2], 15–57 years). Each of these items was correlated with one or more of the values in the PVQ-57 and covered all higher-order values in Schwartz's theory (openness to change, self-enhancement, conservation, and self-transcendence). In summary, the BPVI adequately corresponded with Schwartz's value theory, indicating an acceptable criterion-related validity. This questionnaire is applicable to a wide population, including adolescents, and will be a useful tool for researchers to elucidate the developmental pathway of personal sense of values.     

Covered in stigma? The impact of differing levels of Islamic head‐covering on explicit and implicit biases toward Muslim women

Given the prominence of Muslim veils—in particular the hijab and full‐face veil—in public discourse concerning the place of Muslims in Western society, we examined their impact on non‐Muslims’ responses at both explicit and implicit levels. Results revealed that responses were more negative toward any veil compared with no veil, and more negative toward the full‐face veil relative to the hijab: for emotions felt toward veiled women (Study 1), for non‐affective attitudinal responses (Study 2), and for implicit negative attitudes revealed through response latency measures (Studies 3a and 3b). Finally, we manipulated the perceived reasons for wearing a veil, finding that exposure to positive reasons for wearing a veil led to better predicted and imagined contact (Study 4). Practical and theoretical implications are discussed.     

Genetic and environmental structure of Cloninger's temperament and character dimensions

The multivariate genetic and environmental structure of Cloninger's Temperament and Character Inventory (TCI) was investigated in a sample of 617 pairs of adolescent and young adult twins from Japan. Additive genetic factors accounted for 22% to 49% of the variability on all TCI temperament scales. Although the theory predicts lower heritability for the character scales, all character subscales had a substantial genetic contribution, and nonshared environmental influences accounted for the remainder. Multivariate genetic analyses showed that several subscales used to define one dimension shared a common genetic basis with subscales defining others. Using the degree of shared genetic influence as the basis to rearrange the TCI subscales into new dimensions, it was possible to create genetically independent scales. The implications for personality measurement, theory, and molecular genetic research are discussed.
