Whether preschool males with fragile X syndrome can be distinguished from those with idiopathic developmental delay in the four problem behavior areas associated with the fragile X phenotypes was examined. Males with fragile X (n = 41) and age- and IQ-matched controls (n = 16) were rated by their mothers on the Dimensions of Temperament Scale-Revised, the Child Behavior Checklist, and the Aberrant Behavior Checklist--Community. The fragile X group showed deficits in motor skills, increased initial avoidance, decreased social withdrawal, deficits in attention, increased hyperactivity, and positive mood. They were distinguished from controls on all of these variables except hyperactivity and attention. When maternal characteristics were controlled for, the fragile X group showed a significantly higher level of generalized activity level than did controls.

We contrast the current, clinically based framework for behavior disorder against a life course framework, as an alternative structure upon which to map the variations in onset and stability of clinical symptomatology known to take place in adult life. This alternative developmental framework is used as a base around which to understand known variations in rates of alcohol abuse/dependence over the life course and to review existing schemes for the evaluation of developmental variation in “caseness.” From this work, it was proposed that symptom structure be regarded as a mass of greater or lesser breadth, with properties of extensiveness in time and life course invasiveness, as a function of where in the life course the symptomatology first emerged, and the degree to which the mass sustained itself in developmental time. This framework guided the construction of a time-based measure of alcohol related symptomatology, called the Lifetime Alcohol Problems Score (LAPS). The LAPS discriminated among a variety of alcohol-specific and nonalcohol-specific measures of alcohol-related difficulty, including diagnosis of alcohol dependence, having been in treatment, level of other psychopathology, and measures of family disorganization. The measure has potential applicability for prospective studies, and in estimating clinical prognosis. The utility of the paradigm as a framework within which to conceptualize the emergence, ebb, and flow of other behavior disorders is also discussed.

Suicide is the 2nd leading cause of death for youth aged 10 to 24. Research informed prevention efforts have the opportunity to decrease risk for suicidal ideation and behavior before it is manifested. Indeed, there is a small body of research findings demonstrating both proximal and distal effects of preventive interventions delivered in childhood and adolescence on suicidal ideation and/or behavior. These efforts build off of other secondary analyses of prevention research that has demonstrated benefits for multiple types of youth outcomes. This supplement provides ‘proof of concept’ that family-based preventive interventions aimed at reducing a number of risk factors for suicide (e.g., substance use, externalizing and internalizing behavior) can prevent suicidal ideation and behaviors.

Although there is a common core of agreement in parental perceptions of their preschool-age sons' problem behavior, perceptions of 107 parents became more concordant as fathers increased the amount of time they spent with their sons. At least within the context of a sample who were at risk for developing abuse of alcohol or other substances and antisocial behavior, fathers who spent less time with their sons perceived them to be less troubled than mothers perceived them to be.
