Answer the following seven items based upon the research scenario below.

You are a researcher studying the impact of parenting style on the overall self-esteem of late adolescent teenagers from age 15-18 years old. Parenting style is

defined as parents either having authoritarian, authoritative, or permissive parenting styles. The adolescent participants that are the basis for this study will then

be assigned to groups according to whether they describe their parents as authoritarian, authoritative, or permissive. Self-esteem is measured by the Late-Adolescent

Self-Esteem Scale (LASES), which measures overall self-esteem on a scale from 0-100 (with higher scores indicating higher self-esteem measured by number of times one

feels positively across several situations).
