An important construct in positive psychology is life satisfaction (LS). Although its importance has been recognized by some school psychologists, research findings have remained unsynthesized. In this article, theory, measurement, and correlates of LS among children and youth are reviewed. Following this review, interrelationships among LS research, positive psychology, and school psychology are discussed.

The psychometric properties of a children's life satisfaction measure (MSLSS; Huebner, 1994) were assessed with a middle school sample of 291 students. Similar to findings with elementary school students, the MSLSS demonstrated preliminary evidence of reliability and validity for research purposes. The results of confirmatory factor analyses supported the five satisfaction domains identified in previous research with younger students, along with a single higher-order general life satisfaction factor. Relationships among life satisfaction domains, demographic variables, and social desirability responses were discussed. Potential uses of the MSLSS and future research needs were also discussed.

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurobehavioral disorder affecting 5% to 10% of children. Although considered to be a highly familial disorder, ADHD heritability estimates of 60% to 80% highlight the considerable role that environmental factors may still play in disorder susceptibility. Proposed ADHD environmental risk factors include prenatal substance exposures, heavy metal and chemical exposures, nutritional factors, and lifestyle/psychosocial factors. This paper reviews the literature published in 2010 investigating the association between environmental risk factors and ADHD or related symptomatology. Sources of risk factor exposure and the proposed mechanism by which each exposure is linked to ADHD-related neurobehavioral changes are also reported. Methodologic limitations of the current literature are discussed, and guidelines for future study are proposed. An improved understanding of the role that environmental factors play in ADHD etiology is critical to future ADHD prevention efforts.
