Development of behavioral and emotional problems in Tourette syndrome.

Tourette syndrome is a movement disorder with multiple neuropsychiatric features. Using the parent form of the Child Behavior Checklist by Achenbach and Edelbrock, we identified behavioral and emotional difficulties in 78 males, 6-16 years of age, with Tourette syndrome. Symptoms most often identified included obsessive-compulsive behavior, aggressiveness, hyperactivity, immaturity, withdrawal, and somatic complaints. Abnormal checklist scores were most prevalent in adolescents with Tourette syndrome. Tic severity was not a statistically significant predictor of behavioral disturbance, although a suggestive relationship between tic severity and behavioral disturbance was observed in the 12- to 16-year-old group. Dividing Tourette syndrome patients into those with or without hyperactivity failed to identify whether hyperactivity had a major impact on abnormal behaviors. Our results illustrate the relative frequency of psychopathology in Tourette syndrome and emphasize the need for a comprehensive approach to this syndrome.

Behavioural disorder in the mentally handicapped. The role of life events.

A retrospective study of 65 consecutive referrals for behavioural disorder of mentally handicapped patients living in the community revealed that 31 of these were associated with life events sustained in the 12 months prior to the referral. These patients were usually mildly handicapped, while those who presented with behaviour disorder without a history of recent life events were usually more severely retarded. The differences between the two groups are discussed and the need for further research emphasised.

[Use of the Küchenhoff continuity correction of the Lehmacher CFA test in search of types of sociogenic behavior disorders].

To avoid anticonservative rejections of CFA null hypotheses when using Lehmacher's test Küchenhoff suggested to apply a continuity correction. This correction reduces the differences between observed and expected cell frequencies by a constant. The present paper discusses this variant of Lehmacher's test. Application of the correction for continuity in the search for types of sociogene neuropathology are presented. The discussion covers the effectivity of CFA tests in connection with Holm's method of alpha adjustment.

The risk and protective functions of perceived family and peer microsystems among urban adolescents in poverty.

Utilized a pattern-based approach to discover the different constellations of perceived social transactions separately for family and peer systems and explored the risk and protective functions of these microsystem profiles for both depression and antisocial behavior among a sample of ethnically and racially diverse urban adolescents living in poverty. Measures of perceived social support, involvement and hassles with family and peers, as well as perceived social acceptance and peers' values were entered into two sets of iterative cluster analyses to identify distinct profiles of family and peer transactions. From each of the perceived family and peer transactional analyses, six replicated profiles emerged. Several of the profiles were consistent with expectations from prior literature such as Enmeshing families and Rejecting peer networks, while others were novel and intriguing such as Entangling peers. Family profiles were consistent in their risk and protective associations for both depression and antisocial behavior, while the peer profiles varied in their effects for each developmental outcome. For example, the Rejecting peer profile placed adolescents at increased risk for depression but protected them from antisocial behavior. Implications for future research and preventive intervention are discussed.

Physical recklessness in adolescence. Trait or byproduct of depressive/suicidal states?

The authors assessed adolescents (264 psychiatric inpatients and 742 high school students) with a new instrument (the Sommerfeldt-Clark Adolescent Recklessness Scale) to test whether adolescents show individual differences on a dimension ranging from physical caution to physical recklessness. The three dimensions that emerged reflect an interest in weapons and military dangers, which we have tentatively labeled "foolhardiness"; the combination of dangerous driving and substance abuse; and involvement with smoking, drug use, and "bad company." The personality traits of "venturesomeness" and "impulsiveness" were significantly correlated with all three recklessness factors. The first two factors showed no significant relationship with patient status, diagnosis of mood disorder, or history of suicidal behavior; the third factor was associated with inpatient status and a history of suicide attempts.

Do deviant peer associations mediate the contributions of self-esteem to problem behavior during early adolescence? A 2-year longitudinal study.

We investigated deviant peer associations as a mediator of the influences of general and peer-oriented self-esteem on problem behavior using data from a 2-year longitudinal study of 350 young adolescents. Measures of problem behavior included substance use (alcohol use, smoking) and antisocial behavior (fighting, stealing). Using latent growth curve modeling and covariance structure analysis, an extension of a model proposed by DuBois et al. (2002) was evaluated for each type of problem behavior. Findings revealed that lower general self-esteem and greater peer orientation in self-esteem each predicted deviant associations with peers and that deviant peer associations, in turn, were associated with higher levels and rates of change in problem behavior. Deviant peer associations mediated the associations of general and peer-oriented self-esteem with levels and rates of change in problem behavior such that direct paths from self-esteem to problem behavior generally were nonsignificant.

Neuroimaging and neuropathological studies of depression: implications for the cognitive-emotional features of mood disorders.

Neuroimaging technology has provided unprecedented opportunities for elucidating the anatomical correlates of major depression. The knowledge gained from imaging research and from the postmortem studies that have been guided by imaging data is catalyzing a paradigm shift in which primary mood disorders are conceptualized as illnesses that involve abnormalities of brain structure, as well as of brain function. These data suggest specific hypotheses regarding the neural mechanisms underlying pathological emotional processing in mood disorders. They particularly support a role for dysfunction within the prefrontal cortical and striatal systems that normally modulate limbic and brainstem structures involved in mediating emotional behavior in the pathogenesis of depressive symptoms.

Patient satisfaction among the residential population of a psychiatric hospital.

Patient satisfaction with the interpersonal and amenities aspects of care in a psychiatric hospital was investigated in an Australian setting. The study was carried out among the long-term residential population of a psychiatric hospital and involved 112 out of 195, or 57% of all eligible patients. Cluster analysis identified seven major groups of related items concerning the patients' views of hospital life and their perception of problems. The study largely replicated the findings of an English investigation, showing that many of the same underlying clusters of satisfaction-dissatisfaction with life in a psychiatric hospital emerge, across widely geographically separated settings. The results from the present study further indicate that improvements in autonomy for the patients and a greater say in the running of wards are more important factors contributing to satisfaction with life in a hospital than the physical surroundings themselves.
