Detailed Description

After institutional review board approval, a Pilot study including 30 patients will be conducted to validate Morisky Medication Adherence Scale 8 to validate the questionnaire for cross cultural variation. The data collected will be analyzed and result will be submitted to institutional review board for approval to conduct the parent study. Following the above approval, all adult patients , more than 18 yrs. of age, who are on a strong opioid for their chronic cancer pain, taken prescription from pain clinic at least once in past, who are able to understand and communicate Hindi will be invited to participate in the study.

The precise scoring and permission to use the Hindi translation of the scale has been obtained from the developer. For income we will be considering private and general category of the patients respectively.Data will be analyzed using International Business machines software package for statistical analysis version 20.0.Pilot study data will be analyzed applying tests as internal consistency (Cronbach's alfa), Test retest variability and factor analysis.For parent study in the uni-variate analysis all variables listed above will consecutively tested for significant associations with ''good adherence'' as the outcome variable. Chi-square tests and Student's t-tests will used for categorical and continuous variables, respectively. All variables will be unconditionally entered into a binary logistic multi variate analysis. All p values #0.05 will regarded as statistically significant.
