While there is a plethora of information on addiction relapse, research is lacking on whether or not there is a measurable effect on relapse rates by clients completing a residential treatment stay. Additionally, there is a dearth of research about whether a previous residential stay could impact the length of time before an addict seeks additional inpatient treatment. My objectives were to determine the correlations between various factors and relapse and program readmittance times. The experiment was done via a confidential survey taken voluntarily by a total of 46 individuals, including 24 women and 22 men in residential drug rehabilitation programs for the second or more time. Linear analysis was done using SAS. Only two variables were found to be significant to the relapse model: religious background and how long the respondent had been employed at the time of their relapse. For the readmittance model, if the respondent took depressants, they were more likely to be readmitted to a rehabilitation program. Lastly, there is some ambiguity surrounding the significance of unemployment time and time until relapse as they relate to the readmittance model, but those are possibly also significant.
