General Strain Theory and the Relationship Between Early Victimization and Drug Use

This study uses general strain theory to examine the direct and indirect relationship between early victimization and drug use. Few previous studies measure strain as victimization. Also, past studies tend to combine drug use measures with delinquency measures. This study expands this research by operationalizing strain as early victimization and using measures of both frequency and onset of drug use. National Survey of Adolescents data is used to test the hypotheses. The results show that when youth are victimized they will use drugs more frequently and use drugs at a younger age. These relationships were only partially mediated by social bonds and negative emotions.     

Influences on the Food Choice Behaviors of Adults With Severe Mental Illness

The objective of this research was to gain a deeper understanding of factors influencing the healthiness of food choice behaviors of community-dwelling adults with severe mental illness. Semi-structured interviews were conducted in an outpatient treatment facility with 20 program participants and 10 staff. Grounded theory analysis methods were used. Five dominant themes emerged: food availability, preference for simple food preparation, perceived cost of food, complexity of choice, and relative importance of healthy food choices. The theme of medication effects only emerged from staff interviews. This research can be useful to inform the design of nutrition interventions for this population.     

Motor Schema Formation and Retention in Young Children

The variability-of-practice hypothesis, a major prediction of Schmidt’s (1975) motor schema theory, was tested in an attempt to investigate motor-schema formation. In addition, schema retention was observed after a 2-week retention interval. The task involved preschool children in tossing a bean bag for appropriate distance. Four treatment groups received 100 practice trials equally divided over five days. Variation was provided by varying the weights of the bean bags. The testing situations involved tossing a criterion weighted bean bag as well as a novel weighted bean bag which none of the groups had experienced previously. In addition, all groups were tested on a new but similar task. The results supported the variability-of-practice hypothesis in terms of schema formation and transfer to novel tasks in the same movement class. After a two-week retention interval, loss in performance was significantly less for the group with variability of practice than all other groups.     

Temperament and Gender: Correlates of Toddler Social Competence

The relation between temperament, gender, and social competence was examined in a sample of 202 children ranging from 12 to 36 months of age. Gender and specific characteristics of temperament corresponded more with toddler social competence than did a more general style of temperament. Females were rated by mothers and group caregivers as more socially competent than males on all four measures used in the study and significantly more so on three of these measures. Characteristics of temperament most closely associated with toddler social competence were approach/withdrawal, adaptability to change, and general quality of mood.
