Locus of Control (LOC) refers to an individual’s personal belief that the events that occur in life are either a result of personal control and effort, or outside forces such as luck (Harvey & Thomas, 2004). Individuals with an internal LOC are known to be self-motivators, put forth more effort toward reaching goals and maintain greater control over their lives. Various researchers have found a connection between individuals with an internal LOC and academic achievement and control over their own health (Harvey & Thomas, 2004; Mackey, 2002; MacArthur & MacArthur, 1999). Those individuals labeled as having an external LOC are prone to blame others for their defeats as well as accomplishments and are less likely to work hard to achieve a goal due to a belief that luck is more powerful than they are. For this study, it was hypothesized that high school students who were identified as having an internal LOC would maintain higher grade point averages, study more frequently, use seatbelts with more regularity and consume less alcohol and tobacco. The Multidimensional Health Locus of Control (MHLC) Scale (Wallston, 1976) was administered to 121 high school students. In addition, the students completed a survey that included demographic information as well as questions related to common health-related behaviors such as tobacco, alcohol and seatbelt usage. Of the 76 completed surveys, 38 subjects were identified as “high internals” or “high externals”. To identify any relationships between a student’s LOC and his/her achievement or health choices, SPSS was utilized to run Pearson correlations between LOC and student grades; hours of study time; school involvement; and seatbelt, alcohol and tobacco use. None of the factors measured showed significant correlations to LOC. However, other relationships were found. At the .05 significance level, there was an inverse relationship between school involvement and alcohol use. Also, at the .05 level of significance there was a negative relationship between hours spent studying and alcohol use. At the .01 significance level, an unanticipated positive correlation was found between alcohol abuse and seatbelt use. According to the surveys, students who consumed alcohol more frequently also used their seatbelts with more regularity. Therefore, it appeared that students who spent more time in school activities and studying were less likely to use alcohol. Also, those students who did use alcohol appeared to more regularly use seatbelts than students who either didn’t drink or drank less frequently.Keyword(s): health promotion, student issues
