RESUMEN

Elevated number of parental Communication Deviance (CD) has been connected with psychiatric and thought disorders in their offspring. However, no earlier systematic efforts have been made to review this issue. The aim of this study was to survey the existing literature systematically and perform a meta-analysis of this association. A literature search for published and unpublished observational studies on the association of parental Communication Deviance with psychopathology in the offspring was conducted. Multiple electronic databases were searched (from 1960 to 2012) and the reference lists of the resulting publications were scanned. The findings were pooled using random effect meta-analysis. A total of 19 relevant papers were found and accessed. The results showed that a high level of parental CD is associated with schizophrenia spectrum disorders in the offspring. A large overall effect size (0.79) was found in the meta-analysis. No meta-analysis could be performed on the association of parental CD with an offspring's thought disorders, but the results suggest that such an association may exist. Parental Communication Deviance is associated with schizophrenia spectrum disorders in the offspring. High parental CD could be treated as an indicator of a risk of developing a schizophrenia spectrum disorder, at least among high-risk groups.

RESUMEN

The aim of this study was to investigate whether severe formal thought disorders and mature thinking are stable among adoptees (=187) drawn from the Finnish adoptive family study of schizophrenia. A group of 93 adoptees genetically at high risk (HR) and 94 at low risk (LR) for schizophrenia were assessed blindly and reliably using the Index of Primitive Thought (IPT) and the Index of Integration (IOI). Two assessments of the IPT and the IOI were performed with the mean interval of 11 years. Comparisons of the IPT and the IOI mean scores were conducted both at baseline and at follow-up between adoptees at low and high genetic risk, gender, and psychiatric status. The main result was that the IOI as well as the IPT of the adoptees at the initial assessment predicted the IOI and the IPT estimated at follow-up, thus indicating the stability of severe formal thought disorders and mature thinking over time. The stability of IOI or IPT was not related to genetic risk, gender or psychiatric status or their interactions.

RESUMEN

BACKGROUND: Thought disturbances are commonly associated with psychiatric disorders, especially schizophrenia. Our aim was to clarify whether thought disorders are only stable at certain severity levels and in the presence of certain schizophrenia factors of the Thought Disorder Index (TDI) scale. Furthermore, we also examined the significance of genetic status and the psychiatric disorder for the persistence of TDI severity levels and factors. METHODS: The thought disorders of 158 adoptees genetically at high-risk or low-risk for schizophrenia participating the Finnish Adoptive Family Study of Schizophrenia were evaluated twice at a mean interval of 11 years. Thought Disorder Index (TDI) was used to assess the severity levels and schizophrenia factors. TDI identifies 23 different items of thinking disturbances, which are weighted along a continuum of severity. RESULTS: Thought disorders at the 0.50 and 0.75 severity levels and idiosyncratic verbalization indicative of the schizophrenia factors turned out to be stable phenomena throughout the follow-up period. The adoptees' genetic or psychiatric status was not associated with the results. CONCLUSIONS: The study shows that the stability of TDI seems to be related to the most severe categories of thought disorders. However, of the specific schizophrenia factors, idiosyncratic verbalization, but not confusion and fluid thinking, showed stability over time. Although idiosyncratic verbalization does not necessarily represent the most severe type of thought disturbance, it turned out relatively stable and we can speculate that idiosyncratic verbalization have some predictive value, too.

RESUMEN

The aim of the study was to evaluate whether thought disorders are stable, trait-like features specific to subjects who have a genetic liability to schizophrenia or a psychiatric disorder. The thought disorders of adoptees genetically at high risk (HR) or low risk (LR) for schizophrenia from the Finnish adoptive family study of schizophrenia were evaluated twice at a mean interval of 11 years, using the sum of the Thought Disorder Index (TDI) scores on the Rorschach (TD(R)). At the initial assessment, the mean TD(R) scores of women were significantly higher than those of men, while no association between genetic risk and psychiatric status or their interactions with the TD(R) scores at baseline were found. The main finding was that the initial TD(R) scores statistically significantly predicted the TD(R) scores at follow-up, thus indicating the stability of thought disorder over time. However, neither genetic or psychiatric status nor gender or any interaction between these variables associated with TD(R) at follow-up.

RESUMEN

This study investigated crisis intervention in three secondary schools after the suicides of five students, focusing on the relation between crisis intervention and suicide contagion. The contagion hypothesis was supported. Following a suicide, the number of suicides that occurred in secondary schools in one year were markedly increased beyond chance. No new suicides took place at schools where adequate first talk-throughs and psychological debriefing were conducted by a mental health professional. Proper crisis intervention is recommended to prevent suicide contagion in schools.

RESUMEN

This study investigated crisis intervention in three secondary schools after the suicides of five students, focusing on the 89 classmates' risk of developing symptoms of PTSD (measured by IES) and high intensity (HI) grief as measured by Hogan Sibling Inventory of Bereavement. Crisis interventions for the students varied from none to first talk-throughs and psychological debriefings. Six months after the suicide, 30% of the classmates evidenced scores indicative of PTSD and 9.8% evidenced HI grief. Friendship was a predictor of PTSD and HI grief. Inadequate crisis intervention was a risk factor for HI grief. Proper crisis intervention, and appropriate screening and focused post-trauma psychotherapy after a suicide of a student are recommended.

RESUMEN

Communication deviance (CD), forms of communication that are not bizarrely thought disordered but are hard to follow and that make difficult the consensual sharing of attention and meaning, has been hypothesized as a nonspecific contributor of rearing parents to psychopathology of offspring, including schizophrenia. This hypothesis, or an alternative of genetic transmission, would gain plausibility if CD has long-term stability. CD was evaluated, using tape-recorded and reliably scored Rorschachs in 158 Finnish adoptees, and retested after a median interval of 11 years. Adolescent CD was not stably correlated with follow-up CD. However, initial CD at a mean age of 32 and follow-up CD were significantly correlated. Gender, genetic risk for schizophrenia, and DSM-III-R (American Psychiatric Association, 1987) psychiatric diagnoses had no effect on adult CD stability. CD appears to be a stable, traitlike feature of adult but not adolescent functioning.

RESUMEN

OBJECTIVE: To evaluate the genetic contribution to schizophrenia using an adoption design that disentangles genetic and environmental factors. METHOD: Finnish hospital diagnoses of schizophrenic/paranoid psychosis in a nationwide sample of adopting-away women are compared with DSM-III-R research diagnoses for these mothers. DSM-III-R diagnoses of their index offspring are blindly compared with adopted-away offspring of epidemiologically unscreened control mothers. RESULTS: Primary sampling diagnoses of index mothers were confirmed using DSM-III-R criteria. Lifetime prevalence of typical schizophrenia in 164 index adoptees was 6.7% (age-corrected morbid risk 8.1%), significantly different from 2.0% prevalence (2.3% age-corrected morbid risk) in 197 control adoptees. When adoptees with diagnoses of schizoaffective disorder, schizophreniform disorder, schizotypal disorder and affective psychoses were added, the contrast between the index and control adoptees increased. CONCLUSION: The genetic liability to 'typical' DSM-III-R schizophrenia is decisively confirmed. Additionally, the liability also extends to a broad spectrum of other psychotic and non-psychotic disorders.

RESUMEN

BACKGROUND: Diverse forms of thought disorder, as measured by the Thought Disorder Index (TDI), are found in many conditions other than schizophrenia. Certain thought disorder categories are primarily manifest during psychotic schizophrenic episodes. The present study examined whether forms of thought disorder qualify as trait indicators of vulnerability to schizophrenia in persons who are not clinically ill, and whether these features could be linked to genetic or environmental risk or to genotype-environment interactions. The Finnish Adoptive Study of Schizophrenia provided an opportunity to disentangle these issues. METHODS: Rorschach records of Finnish adoptees at genetic high risk but without schizophrenia-related clinical diagnoses (N = 56) and control adoptees at low genetic risk (N = 95) were blindly and reliably scored for the Thought Disorder Index (TDI). Communication deviance (CD), a measure of the rearing environment, was independently obtained from the adoptive parents. RESULTS: The differences in total TDI between high-risk and control adoptees were not statistically significant. However, TDI subscales for Fluid Thinking and Idiosyncratic Verbalization were more frequent in high-risk adoptees. When Rorschach CD of the adoptive rearing parents was introduced as a continuous predictor variable, the odds ratio for the Idiosyncratic Verbalization component of the TDI of the high-risk adoptees was significantly higher than for the control adoptees. CONCLUSIONS: Specific categories of subsyndromal thought disorder appear to qualify as vulnerability indicators for schizophrenia. Genetic risk and rearing-parent communication patterns significantly interact as a joint effect that differentiates adopted-away offspring of schizophrenic mothers from control adopted-away offspring.

RESUMEN

Subtle motor, emotional, cognitive and behavioral abnormalities are often present in apparently healthy children and adolescents who later develop schizophrenia. This suggests that some aspects of causation are established long before psychosis is manifest. We aim to develop a descriptive model of the factors contributing to the development of schizophrenia. Our main focus is on genetic factors, pregnancy and delivery complications, early development and scholastic performance. This is done by reviewing the Northern Finland 1966 Birth Cohort, its scientific activities (publications and work in progress) and selected literature.

RESUMEN

The qualitative study reported in this paper aims to describe the planning and assessment of psychiatric nursing in a hospital environment. The theoretical framework consists of the three types of psychiatric nursing outlined in a developmental model of nursing: confirmatory, educational and catalytic. Confirmatory psychiatric nursing is based on a hierarchical and authoritarian model. Educational psychiatric nursing is based on a professionally driven and behavioural model. Catalytic psychiatric nursing is systematic, theoretical, and research-based. Catalytic psychiatric nursing may vary, depending on the patient's needs, from confirmatory and educational to situationally determined nursing. However, it always enables patient initiatives. The purpose of this paper is to describe patient initiatives during the assessment and planning of patient care by an interdisciplinary mental health team in a psychiatric hospital environment, and the assessment and planning as described by nurses working in a hospital environment. The data, which were collected in two psychiatric hospitals by videotaping interdisciplinary teamwork situations and recording interviews of nurses afterwards, consisted of 384 pages of written text. A total of 640 sentences were identified in the text as reflecting the assessment of care by the interdisciplinary team and by the nurses working in the hospital environment. Deductive content analysis techniques were used to analyse the written data. The results showed that nursing was described by the nurses to be catalytic in 13% of the cases, while the same nurses assessed psychiatric nursing to be most commonly educational (40%) or confirmatory (47%).

RESUMEN

In this article we review the thirty-year-old person from the viewpoint of the development psychology, life span, physical health and family life. In his psychological development a person has at this stage become adult, but he still uses some psychic mechanisms and coping strategies which are typical for the adolescent. Intrapsychic world, the working role and the family life are stabilizing, but the changing over to the independence and working life can be more difficult today than earlier. Although with most people the adult life has settled down and physical and psychiatric illnesses are relatively rare, part of the thirty-year-olds are not independent, placed to the working life or are not healthy. In the following paper, main theories or findings in psychological and family life development and mental health of a thirty-year-old person are presented.

RESUMEN

OBJECTIVE: This study assessed the interaction of genetic risk and rearing-family risk as a subsyndromal test measure of schizophrenic thought disorder in adoptees. METHOD: A group of 58 adoptees with schizophrenic biological mothers was compared with 96 comparison adoptees at ordinary genetic risk; putative adoptee vulnerability was assessed blindly and reliably by using the Rorschach Index of Primitive Thought. Environmental risk was measured by using frequency of communication deviance as a continuous variable, scored independently from Rorschach assessments of the adoptive parents. RESULTS: High genetic risk in itself was not associated with greater vulnerability to schizophrenic thought disorder in the adoptees, as indicated by the Index of Primitive Thought. Also, greater communication deviance in the adoptive parents was not associated with greater thought disorder in the comparison adoptees. However, there was a highly significant gene-environment interaction. Among the offspring of the adoptive parents with high levels of communication deviance, a higher proportion of high-risk than comparison adoptees showed evidence of thought disorder. In contrast, among the offspring of adoptive parents with low communication deviance, a lower proportion of high-risk than comparison adoptees showed evidence of thought disorder. The distribution of communication deviance scores did not differ significantly between the adoptive parents of high-risk offspring and the adoptive parents of comparison offspring. CONCLUSIONS: The findings are consistent with genetic control of sensitivity to the environment. There is no evidence that high genetic risk of schizophrenia among offspring is associated with high levels of communication problems in rearing parents.

RESUMEN

A nationwide Finnish sample of schizophrenics' offspring given up for adoption was compared blindly with matched controls, who were adopted offspring of non-schizophrenic biological parents. The adoptive families were investigated thoroughly using joint and individual interviews and psychological tests. The biological parents were also interviewed and tested. Among the 155 index offspring, the percentage of both psychoses and other severe diagnoses (borderline syndrome and severe personality disorders) was significantly higher than in the 186 matched control adoptees. This supports a genetic hypothesis. However, notable differences between these two groups only emerged in the families which were rated as disturbed. Thus the genetic effect (i.e. the differences between high and low genetic propensity) was only manifested as a psychiatric disorder in the presence of a disturbed family environment. The impact of disturbed family relations was strongest in the presence of the appropriate genotype.

RESUMEN

A nationwide Finnish sample of index offspring given up for adoption by schizophrenic women has been compared blindly with matched controls, that is, adopted-away offspring of nonschizophrenic biologic parents. The adoptive families have been investigated directly by joint and individual interviews and psychological tests. Interviewing and testing of biologic parents is in progress. In the total sample, thus far examined, of 124 index offspring, 9 (7.3%) have become psychotic; of 147 control offspring, 2 (1.4%) have become psychotic.

RESUMEN

A nationwide Finnish sample of schizophrenic mothers' offspring given up for adoption was compared blindly with matched controls (i.e., adopted-away offspring of nonschizophrenic biological parents). The offspring were born 1927-79. To date, a total of 247 adoptive families (112 index and 135 controls) have been investigated and rated. Of the 10 psychotic cases, 8 are offspring of schizophrenics and 2 are control offspring. However, no seriously disturbed offspring is found in a healthy or mildly disturbed adoptive family, and of those offspring who were psychotic or seriously disturbed, nearly all were reared in disturbed adoptive families. This supports the hypothesis that a possible genetic vulnerability has interacted with the adoptive rearing environment.

RESUMEN

A nationwide Finnish sample of schizophrenic mothers' offspring given up for adoption has been compared blindly with matched controls; i.e., adopted-away offspring of non-schizophrenic biologic parents. The families have been investigated thoroughly by joint and individual interviews and psychological tests. In the 91 pairs where both the index and control families have already been investigated and rated, the total number of severe diagnoses (psychosis, borderline, character disorder) is 28.6 percent (26/91) in the index group and 16.5 percent (15/91) in the matched control group. Of the seven psychotic cases, six are offspring of schizophrenics and only one is a control offspring. However, no seriously disturbed offspring has been found in a healthy or mildly disturbed adoptive family, and those offspring who were psychotic and seriously disturbed were nearly all reared in disturbed adoptive families. This combination of findings supports the hypothesis that a possible genetic vulnerability has interacted with the adoptive rearing environment.

RESUMEN

What the genetic and family dynamic theory have in common, is that the cause of schizophrenia could be found in the family. Usually the genetic factors and the rearing factors are confounded in the same family. In a study of adoptive children given away for adoption early enough, discrimination between these two sets of factors is possible. A nation-wide sample of offspring of schizophrenic mothers, given away for adoption, has been compared blindly with matched controls, i.e., adopted-away offspring of non-schizophrenic biologic parents. The families have been investigated thoroughly with joint and individual interviews and psychological tests. In the 91 pairs where both the index and control families have been investigated and rated so far, the total number of severe diagnoses (psychosis, borderline, character disorder) is 28.6% (26/91) in the index group and 16.5% (15/91) in the matched control group. Of the 7 psychotic cases, 6 are offspring of schizophrenics and only one a control offspring. The relation of psychopathology of adoptive families to the mental health ratings of the offspring supports the hypothesis that a possible genetic vulnerability has interacted with the adoptive rearing environment.
