Illness Perception, Adherence and Health-Related Quality of Life among Individuals with Myocardial Infarction

Abstract

The current study was designed to explore the relationship amongst illness perception, adherence, health-related quality of life, and instrumental activities of daily living among individuals with Myocardial Infarction. For this purpose, responses were collected from 220 individuals (144 males and 76 females). Brief Illness Perception Questionnaire (BIPQ) (Broadbent et al, 2006), General Medication Adherence Scale (GMAS) (Naqvi et al., 2018), Health-Promoting Lifestyle Profile-II (HPLP-II) (Walker et al., 1995), and Lawton Instrumental Activities of Daily Living (IADL) (Lawton & Broody, 1969) were used to assess illness perception, adherence, health-related quality of life and instrumental activities of daily living. The current study aimed to investigate the relationship between the study variables. The study hypothesized that illness perception will have a positive relationship with adherence which will increase health-related quality of life which will further enhance instrumental activities of daily living. The findings of the present study revealed that illness perception is a significant predictor of adherence and adherence significantly predicted health-related quality of life whereas the health-related quality of life did not significantly predict instrumental activities of daily living. A significant positive relationship was found between illness perception and adherence. Similarly, a significant positive relationship was observed between adherence and health-related quality of life as well as between health-related quality of life and instrumental activities of daily living. The study also suggested that adherence plays an indirect mediating role between illness perception and instrumental activities of daily living. The current study also explored the role of several demographic variables (age of the participant, gender, educational level, SES, marital status, monthly income, source of income, family system, previous heart attack, method of treatment, smoking, treatment medication and, family history of the individuals with MI among XXI the study variables.
