Detailed Description

The purpose of this pilot study is to explore the association between personality and adherence to a specific type of oral cancer medication - tyrosine kinase inhibitor (TKI) - in patients with chronic myeloid leukemia (CML). 75 individuals with chronic phase CML who are being treated with TKIs will be recruited. Consenting patients will participate in a focused interview where TKI adherence, personality type, and quality of life and symptom burden will be assessed using validated questionnaires. Information on treatment response and the treating physician's perception of TKI adherence will be obtained from the electronic health record.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of adherence to TKI medication
Time Frame: Up to 1 year
This will be measured by Morisky Medication Adherence Scale (MMAS), an 8-item tool related to adherence behavior include forgetfulness, stopping medication because of worsening of symptoms or improvement in health condition, and inconvenience of continuing medication. Each item is scored 0 or 1 depending on whether the patient answers yes or no, with a minimum score of 0 and maximum score of 8
Up to 1 year
Personality assessment
Time Frame: Up to 1 year
Patient personality will be assessed using the Mini International Personality Item Pool (mini-IPIP) questionnaire. In the mini-IPIP, each of the five factors (openness, conscientiousness, extraversion, agreeableness and neuroticism) is assessed with four items, making a total of 20 items. Each item is scored on a scale of 1 through 5, with 1 indicating "very inaccurate" and 5 corresponding to "very accurate"
Up to 1 year
Assessment of quality of Life
Time Frame: Up to 1 year
This will be measured by European Organisation of Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30). EORTC QLQ C30 includes 30 items that measure global health status, functioning, and symptoms.
Up to 1 year
Assessment of quality of Life and symptom burden
Time Frame: Up to 1 year
This will be measured by European Organisation of Research and Treatment of Cancer Quality of Life Questionnaire Chronic Myeloid Leukemia -24 scales.(EROTC QLQ-CML 24). The EORTC QLQ CML 24 is a 24-item questionnaire developed exclusively to assess QoL issues in patients with CML
Up to 1 year
