The Impact

Background. While the family environment can directly influence later risk for psychopathology, dysfunction in the family of origin may also moderate the impact of genetic factors on liability for psychiatric disorders. Can a similar pattern be seen for the personality trait of Neuroticism (N) – which is a risk factor for many psychiatric conditions?Method. Our sample of 957 complete female–female twin pairs from a population-based register had measures of self-reported N and multiple reporters (twin, co-twin, mother, father) for family dysfunction (FD). Statistical analysis was conducted by traditional regression analysis and a moderator structural equation twin model operationalized in the computer program Mx.Results. Dividing the sample into quartiles based on increasing levels of FD, the mean of N increased substantially while correlations of N in monozygotic (MZ) and dizygotic (DZ) twins were relatively constant. Regression analyses did not suggest greater twin resemblance for N with increasing levels of FD. The best-fit structural equation model was the standard un-moderated model in which the proportion of variance in N due to genetic (39%) and unique environmental effects (61%) remained constant across values of FD.Conclusions. Although a false-negative result due to limited power cannot be excluded, these analyses do not support the hypothesis that FD moderates the impact of genetic factors on levels of N.

The Impact

Background. An adoption study of alcoholism suggests that in women, the impact of genetic risk factors become greater in the presence of conflict in the family of origin. Is the same true for cigarette smoking (CS)?Method. We obtained, in a sample of 1676 twins from female–female twin pairs from a population-based register, a measure of maximum lifetime CS (divided into six ordinal categories) and family dysfunction (FD) assessed as the mean report of up to four informants (twin, co-twin, mother, father). Statistical analysis was conducted by traditional regression analysis and a moderator structural equation twin model using the computer program Mx.Results. With increasing levels of FD, maximum CS increased substantially while correlations for CS in monozygotic (MZ) and dizygotic (DZ) twins decreased modestly. Regression analyses demonstrated reduced twin-pair resemblance for CS with increasing levels of FD. The best-fit structural equation model found high levels of heritability for CS and no evidence for a role of shared environment. With increasing levels of FD, the proportion of variance in CS due to genetic factors (i.e. heritability) decreased while that due to unique environmental effects increased.Conclusions. Several different statistical methods suggested that, contrary to prediction, heritability of CS decreased rather than increased with higher levels of dysfunction in the family of origin. The hypothesis that genetic effects for psychiatric and drug-use disorders become stronger in more adverse environments is not universally true.

Emotional Insecurity

Child-to-parent violence (CPV) constitutes a serious social problem due to its short and long-term consequences, which not only directly affect the victim but also generate a rupture of the family system. In this study, direct and indirect effects of exposition to violence within the family, insecurity in the family system (manifested as disengagement and/or preoccupation), and justification of violence on CPV toward mothers and fathers were analyzed with structural equation modeling (SEM). Davies and Cummings emotional security theory (1994) was applied. A total of 904 high school students between 13 and 20 years old participated in this study. Information regarding each participant’s committed CPV was obtained from the Child-to-Parent Aggression Questionnaire. Emotional insecurity was assessed with the Security in the Family System scale. To assess exposition to violence and justification of violence, the Exposure to Violence Questionnaire and Irrational Beliefs Inventory for Adolescents were applied, respectively. Strong relationships between exposition to violence within the family, emotional insecurity, justification of violence, and CPV toward mothers and fathers were observed. The results show that adolescents who are exposed to violence at home are more aggressive in the future. In addition, this relationship is mediated, at least in part, by the justification of violence and emotional insecurity. These results suggest that prevention and treatment of CPV aggressors should focus on improving security within the survivors’ family system as well as modifying attitudes toward violence.

The distribution of recurrent ear infections was obtained from a population-based sample of 2,750 pairs of Norwegian twins born between 1967 and 1974. The lifetime prevalence of self-reported recurrent ear infections was 8.9%, with a significant predominance of female cases. The mean age of onset was 4.2 years, with a gradual decrease in occurrence from 2 to 7 years of age. Among monozygotic pairs, the rate of tetrachoric correlation between co-twins was almost identical in males (0.73, SE 0.08) and females (0.74, SE 0.06), but among the dizygotic pairs the correlation was clearly higher in males (0.53, SE 0.12) than in females (0.20, SE 0.12). The value in the unlike-sexed dizygotic twins (0.25, SE 0.05) was intermediate to that of the like-sexed male and female dizygotic pairs. The relative contribution of genes and environment to variability in the predisposition to develop otitis media was estimated by means of structural equation modeling. Variation in liability to ear infections was mainly explained by additive genetic and dominance factors in females, for whom heritability was estimated at 74%. The remaining 26% of the variation in liability was explained by individual environmental factors. In males, 45% of the variation could be accounted for by genetic factors, 29% by common familial environment, and the remaining 26% by individual environmental effects.

Anti-violence education implemented in various educational environment, equally important the family environment. The impact of violence against spiritual emotional intelligence development of children leads to the negative things. Include that realize or not, violence that showed by parents have instilled hatred and excessive fear in children. Violence will infuse stubborn and rude in children, give wound in the hearts of children until they are adults. Islam teaches anti-violence education, especially on the early chilhood education, have to carry out with great affection. Many verses of the holy Koran which instruct to educate children with affection. The term like qaulan layyinan, qaulan ma'rufan and so on are some command to teach and interact with students full with love and through the good ways. Keyword: anti-violence education, early chilhood. Pendidikan anti kekerasan diterapkan di berbagai lingkungan pendidikan, dan tidak kalah pentingnya yaitu lingkungan keluarga. Dampak kekerasan orang tua terhadap perkembangan kecerdasan emosional spiritual anak ini mengarah pada hal-hal yang negatif. Dampak tersebut diantaranya adalah: sadar atau tidak kekerasan yang dilakukan orang tua telah menanamkan kebencian dan rasa takut yang berlebihan pada diri anak. Kekerasan akan menanamkan sifat keras dan sikap kasar pada diri anak, membekaskan luka di hati anak hingga mereka dewasa. Islam mengajarkan pendidikan yang bersifat anti kekerasan, apalagi dalam konteks mendidik anak usia dini, dilakukan dengan penuh kasih sayang. Banyak ayat al-Qur’an yang memerintahkan mendidik anak dengan kasih sayang kepada putra-putranya yang masih kecil. Bahasa qaulan layyinan, qaulan ma’rufan dan sebagainya merupakan perintah untuk mendidik dan berinteraksi dengan anak didik dengan penuh kasih sayang dan cara yang baik.

The Impact

The relatively hereditary character of diverse cultural phenomena has already drawn attention to the role that the family can play in this trans mission. It appears in particular that political orientations and the chances of access to different types and levels of education can frequently be explained by a specific family membership. Two types of argument are put forward here in order to explain how the family can appear as a privileged place of cultural apprenticeship: on the one hand psychological arguments linked with the primary and universal character of family education and the type of relations that this develops; on the other hand a more sociological explanation based on the repercussion that the more or less great complexity of learned language entails with regard to diverse exterior participations, and on the comparison between the impact of the family and those of other socializing agents on the successive choices which they will impose. To these explanatory elements of the existing link between cultural memberships and the family environment is added, for religion as much as for the family, the transition from the public to the private sphere. This parallel evolution will tend to increase the autonomy of religion on the plane of secondary elaborations for which it will borrow its mode of re-interpretation from the exigencies of daily life, particularly from the family.

ABSTRACTBackgroundThe relationship between personality and psychiatric illness is complex. It is not clear whether one directly causes the other.MethodIn a population-based sample of male twins (n=3030), we attempted to predict major depression (MD) from neuroticism (N) and extraversion (E) and vice versa, to evaluate the causal, scar, state, and prodromal hypotheses. In a longitudinal, structural equation twin model, we decomposed the covariation between N and MD into (a) genetic and environmental factors that are common to both traits, as well as specific to each one and (b) direct causal effects of N at time 1 on subsequent MD, as well as between MD and subsequent N.ResultsE was negatively correlated with lifetime and one-year prevalence of MD. N predicted the new onset of MD, and was predicted by both current and past MD. It did not predict the time to onset of MD. All of the covariation between N and MD was due to additive genetic and individual-specific environmental factors shared by both traits and a direct causal path between MD and N assessed later. No genetic factors were unique to either trait.ConclusionsIn men, N may be a vulnerability factor for MD but does not cause it directly. However, MD may have a direct causal effect on N. The genetic overlap between N and MD in men may be greater than in women.

While it is well-established that education and Right Wing Authoritarianism (RWA) are quite strongly negatively correlated, it is still unclear why this is the case. There could be causal effects between these variables, in one or both directions, which can be either direct or mediated. And there could also be confounding third variables influencing their association. Using a sample of 320 monozygotic- and 312 dizygotic twin pairs, we were able to control for confounding influences from both genes and the family-environment, increasing our ability to infer causal effects. Furthermore, we investigate the roles of perceived Socio-Economic Status (SES) in both childhood and adulthood; SES in childhood could be a confound between education and RWA, and SES in adulthood could be a mediator. We explore these hypotheses with ACE-β models, which extend the logic of discordant twin designs into a structural equation framework. Our results are consistent with a causal effect of education to reduce RWA. SES in adulthood did not mediate this effect. We find that the negative correlation between RWA and education is further amplified by confounding influences, mostly from the family environment, which are partly associated with SES.

An increase in cases of sexual violence against children triggers various health problems in children, both physical, psychological and social. This paper aims to explore the sexual violence on children, risk factors and the impact of sexual violence on children. This study of sexual violence in children refers to various empirical literature studies. Furthermore, the collection of information was analyzed using the problem tree analysis approach to find out the risk factors and their impact on children. Cases of sexual violence in the community are difficult to detect because of the lack of recognition from victims. This is because the offender called pedophile comes from within the family (familial abuse) or can come from outside the family environment (extra-familial abuse) who have established close relationships with children. Sexual violence is generally motivated by the problem of weak protection from parents which is also strengthened by socio-economic problems, low access to reproductive health education and less optimal law enforcement. Therefore, children who have experienced sexual violence find it difficult to avoid physical, biological, psychological and social risks. Children who have experienced sexual violence find it difficult to avoid physical, biological, psychological and social risks. Therefore, it is necessary to increase the capacity of parents in the prevention of sexual violence against children and law enforcement needs to complete the system of early detection and rapid response to the incidence of sexual violence against children.

This study investigated the impact of family climate on the academic achievement of government and private secondary school students. Three hundred (Boys =150; Girls =150) secondary school students were randomly chosen as the sample of the study from 8 schools (4 government and 4 private) of Aligarh. Family Climate Scale by Dr. Beena Shah (1990) was used to study respondent’s family climate, while their IX class examination results were used as the measure of academic achievement. The hypotheses were tested using the product moment coefficient of correlation to find out the relationship between the family climate and academic achievement, and for measuring the effect of the type of family climate (favorable and unfavorable) on the academic achievement of the students the investigator applied t-test. The results showed that the academic achievements of students are independent of the family environment and parental support provided to them. The study also revealed that private students have good academic records in comparison of government students.
